1. KinematicsBe clear with Vectors and Basic Math, and you are done. Practice tons at this stage because you’d have an early practice of solving equations fast.
2. Newton’s Laws of MotionIt might be seeming very tough to you, but don’t worry, by the end of your course you would be really comfortable with it. Practice a lot of questions. I can’t emphasize it more. Be thorough with concepts like friction, strings, and pulleys, Normal force, Circular Motion, etc. Practice till you are perfect.
3. Work Power Energy and GravitationPractice conservation of Energy a lot. It is very important in Physics. Gravitation is linked to this. Again, look out for Energy conservation and Kepler’s law when solving Gravitation questions. Work-Energy Theorem is another important concept. Make yourself comfortable with the topic.
4. Centre of Mass and MomentumOne of the toughest chapters after Rotation. Tough nut to crack. Step one could be trying to remember all concepts and equations. It helps a lot. Be thorough with vectors. Momentum conservation relies a lot on it. Collisions has some interesting problems. Be thorough with the main formulae. Conservation of Momentum and Energy are central here. Remember positions of COM of various objects. It will be very helpful in future. Remember some basic cases in collisions(small object, heavy object, same masses, etc.) Spring questions are common. Be aware of springs in parallel/series, and basic equations.
5. RotationRotation may be a real tough nut, and JEE asks some really awesome questions from this section. This is tough and has got a good weightage. You must give a good amount of time to it. It begins with Moment of Inertia. Learn the MI of varied standards objects, and be thorough with the derivations. It will assist you just in case some questions supported calculating MI comes in JEE. Then there is a discussion of angular velocity, rotational Kinematics, etc. Pretty easy if thorough with basic trigonometry and Kinematics. Then comes torque, angular momentum, etc. This seems tough, but it will come naturally to you with time if you are clear with NLM. Remember there are only few equation, T=I(alpha), and L=Iw. Try to remember these employing a correlation with NLM. Conservation of Angular momentum is very important. Lots of questions are asked from this topic. Be clear with the axis of rotation and the point about which you are trying to conserve it. Massive problem solving will help.
6. Simple Harmonic MotionAnother basic and important topic. Remember the derivation and equations of SHM. Remember the Time Period formulae. It will save a lot of time on the final day. Questions involving finding the period of time of any system are common. Be thorough with them.
7. Fluid Dynamics and ElasticityNot vital but few easy questions come needless to say . You don’t want to miss them. Continuity equation, variation of pressure with depth, and Bernoulli equation are important. Try to do some questions of Surface Tension too(JEE has asked some really tough questions from this topics). Elasticity has a graph of Stress vs Strain. Remember it well. These chapters have a bunch of long equations. Try to remember them. There might be a few questions at least in JEE(Main) where you would need to evaluate the expression.
So, this was it. Coming to the preparation strategy, first of all hear your coaching lecture/online lecture and do homework, and discuss in school if you’re during a coaching. This will help you clear Mechanics.
Coming to books(and hence the self-study guys too) HCV is that the god-book for Mechanics. Read every line(irrespective of whether you’re during a coaching or not), understand everything and solve each question. Solutions are available somewhere on the Internet I guess(don’t know if they are copyrighted or something, so beware). Discuss with teachers. If you sincerely solve all questions of Mechanics then nobody can stop you from being a Master of Mechanics. I also recommend reading NCERT. It gives a wonderful insight into the subject and will prepare you for JEE(Main) and Boards too. If you would like more objective practice, choose DC Pandey Problems book. Deb Mukherjee’s book is really good for conceptual questions. And then comes the GOD- I.E. Irodov. This will prepare you for Olympiads, and for facing any question in JEE(Advanced). Solve this only if you have time and are done with the above stuff. Better do it during Holidays. But trust me, Irodov will offer you an upper edge if you’re aiming for a top 100 rank approximately .

TYPHOID FEVER AND IT’S SYMPTOMS
Typhoid Fever or Typhoid is a systemic enteric infection caused by bacteria usually through ingestion of contaminated food or water. The disease is also referred by several other names such as Gastric Fever, Enteric Fever, Abdominal Typhus, Infantile Remittent Fever, Slow Fever, Nervous Fever, and Pythogenic Fever. The disease causes several symptoms causing mild to severe problems for the patients. The symptoms are generally seen from six to thirty days after exposure. Generally there is the gradual onset of high fever for several days, weakness, abdominal pain, constipation, headaches, and vomiting. Some people also develop a skin rash with red colored spots.
The cause of the disease is the bacterium Salmonella typhi which is also known as Salmonella enterica serotype typhi , mainly growing in the intestines and blood. Risk factors include poor sanitation and poor hygiene. Diagnosis of the disease is done by either culturing the bacteria or detecting the bacterium’s DNA in the blood, stool, or bone marrow. Culturing the bacterium is little bit difficult so Bone marrow testing is the mostly used method. It has been observed that a typhoid vaccine can prevent about 40-90% of the infection during the first 2-7 years. But this vaccine is always recommended for the people at high risk or travelling to the places where this disease is so common. Other efforts which can be done to prevent the disease are clean drinking water, good sanitation, and hand washing. The disease is usually treated with several antibiotics such as Azithromycin, Fluoroquinolones or third generation cephalosporins.
SIGNS AND SYMPTOMS
Usually, the complete course of untreated typhoid fever is divided into 4 different stages, where the each stage lasts for a week which makes the patient completely exhausted.
• In the first week, the body temperature of the patient rises slowly, and the fever fluctuations are generally seen with relative bradycardia, malaise, headache, and cough.
A bloody nose is also seen in this quarter of the disease and abdominal pain is also possible. There is also a decrease in the number of WBCs. Widal test is negative in the first week of the disease.
• In the second week, the person is often too tired to get up, with a very high fever and bradycardia is continued in this stage also with dicrotic pulse wave. In this stage, Delirium is frequent which gives the typhoid another name i.e. NERVOUS FEVER.
Rose spots also appear on the lower chest and abdomen. Rhonchi are heard in lung bases.
Diarrhea can occur in this stage : six to eight stools in a day, green, comparable to pea soup, with a characteristic foul smell. However, constipation is also frequent. The spleen and liver is enlarged and liver transaminases are elevated. Patients can still test positive.
The major symptoms of this fever is that the fever usually rises in the afternoon up to the first and second week.
• In the third week of the fever, a number of complications can occur like :
Intestinal hemorrhage due to bleeding in congested Peyer’s patches: it can be very serious but is not usually fatal.
Intestinal perforation in the distal ileum: this is a very serious complication and is usually fatal.
Encephalitis.
Respiratory diseases such as pneumonia and acute bronchitis.
Neuropsychiatric symptoms with picking at bedclothes or imaginary objects.
Metastatic abscesses, cholestasis, endocarditis, and osteitis.
The fever is usually very high and oscillates very little over 24 hours. Dehydration is also caused.
Platelet count goes down and risk of bleeding rises.
It’s not stress that kills us, it is our reaction to it.
Stress name is enough to load stress on the human mind, however, every person in this world had passed through stress, but the beautiful thing is that how people can handle it and overcome from it, stress is a part of the human mind and Stress is a feeling of emotional or physical tension. It can come from any event or thought that makes you feel frustrated, angry, or nervous. Stress is your body’s reaction to a challenge or demand. In short bursts, stress can be positive, such as when it helps you avoid danger or meet a deadline, it totally depends on the human action on how we can handle positively or negatively by committing a crime or by suicide.
However, our whole life is full of stress, from birth to till death, like after having a birth people start taking decision regarding the future life, when we enter the school at the time teachers and faculty give homework and assignment to finish from home if we don’t complete it, have to face parents, so, we have this stress, further, 10th and 12th exam pass out stress, yet when we pass 12th anyhow, graduation and post-graduation stress, and latest job and marriage stress, at the end of the life stress of pain and diseases. But the major thing is that many people do not wait for old age they lost their life by suicide, their mind and heart are not enough strong to handle the load or not mentally prepare for further future.
In addition, our education system also have fault like they give dept education of History, science, maths, languages and many more, but they do not give lessons on how to handle depression, anxiety and stress, by organizing I.T. fair or science fair student only enjoy, it affects only a few hours. But organizing a stress relief program where students can understand how to handle any life turning modes. After completing the study, people try to find jobs or developing their business, but after a long struggle some get success or many get a failure, and that is the major turn of life if any person handles well, they get the real success in life.
Many famous celebrities are renown by their comeback from stress like famous cricketers Yuvraj Singh, and famous actor Akshay Kumar and Nawazuddin Siddiqui both belong to small and poor families but now every nook and corner people know them. However, in the year between 2009 to till date, around more than 100 celebrities commit suicide in that list include Stephanie Adams, Chester Bennington, David Berman, Joseph Brooks, David Buckel, Malik Bendjelloul and many more they all are from Hollywood, but recently a well-known actor Sushant Singh Rajput committed suicide it just bingeing of the journey and he did a great job by acting as lead actor in MS Dhoni the untold story, Kedarnath, Detective Byomkesh Bakshy!, and Chhichhore.
In Chhichhore, done a great job and he delivered a beautiful line “Hum haar jeet, success failure mein itna ulajh gaye hai … ki zindagi jeena bhool gaye hai … zindagi mein agar kuch sabse zyada important hai … toh woh hai khud zindagi” and by considering this line many failures get motivation and done grate thing in the life, but the lead actor committed suicide, which is not relevant, he has to share his problems with family or friends, he definitely gets a solution and he still present with us.
there are some exercise to overcome from it like, Yoga, Qigong, Walking, Gardening, Dancing, Circuit Training, play Tennis or do some boxing whit pillow on the wall, this all help to relieve stress. nowadays the best way to come out stress is by doing a party or hanging out with friends.
So, considering this all thing, give value to your life, and enjoy your life.

You can share messages, why not blood?
The blood donation happens when a person voluntarily ready to transform their blood into communities without any charges, however, Donation may be of whole blood, or of specific components directly. Blood banks often participate in the collection process as well as the procedures that follow it.
The blood donation process discovered by English physician William Harvey in 1628 but after 36 years thy successfully done blood donation camp in England, the first blood transform done on a dog and Physician Richard Lower keeps dogs alive by transfusion of blood from other dogs people think it is funny incident but it is very seriously a successful transformation.
Today in the developed world, most blood donors are unpaid volunteers who donate blood for a community supply. In some countries, established supplies are limited and donors usually give blood, when family or friends need a transfusion. Many donors donate as an act of charity, but in countries that allow paid donation some people are paid, and in some cases there are incentives other than money such as paid time off from work. Donating is relatively safe, but some donors have to bruise where the needle is inserted or may feel faint. Potential donors are evaluated for anything that might make their blood unsafe to use. The screening includes testing for diseases that can be transmitted by a blood transfusion, including HIV and viral hepatitis. The donor must also answer questions about medical history and take a short physical examination to make sure the donation is not hazardous to his or her health. How often a donor can donate varies from days to months based on what component they donate and the laws of the country where the donation takes place. Ex. in many countries the doner have to wait for two to three weeks to rebuild their blood counts and proper growth of their blood portion. A typical donation is 450 milliliters of whole blood, though 500-milliliter donations are also common. Historically, blood donors in India would donate only 250 or 350 milliliters.
There are two main methods of obtaining blood from a donor. The most frequent is to simply take the blood from a vein as whole blood. This blood is typically separated into parts, usually red blood cells and plasma since most recipients need only a specific component for transfusions. The other method is to draw blood from the donor, separate it using a centrifuge or a filter, store the desired part, and return the rest to the donor. This process is called apheresis, and it is often done with a machine specifically designed for this purpose.
What precautions have to take donor after blood donation, they have to lay down for 10 to 15 minutes at the bead, then take light refreshments, such as orange juice and cookies, or a lunch allowance to recover speedy, The needle site wound is covered with a bandage and the donor is directed to keep the bandage on for several hours. And in last avoid strenuous exercise and games, alcohol and other kinds of physical exercise.
People from non-science backgrounds have questions that how doctors store blood for a long time?, here is the answer, Red blood cells, the most frequently used component, have a shelf life of 35–42 days at refrigerated temperatures. For long-term storage applications, this can be extended by freezing the blood with a mixture of glycerol, but this process is expensive and requires an extremely cold freezer for storage. Plasma can be stored frozen for an extended period of time and is typically given an expiration date of one year and maintaining supply is less of a problem.
Here is the table display that, which blood group person can donate to whom.
| If your blood type is: | You can give to: | You can receive from: |
|---|---|---|
| O Positive | O+, A+, B+, AB+ | O+, O- |
| A Positive | A+, AB+ | A+, A-, O+, O- |
| B Positive | B+, AB+ | B+, B-, O+, O- |
| AB Positive | AB+ Only | All blood types |
| O Negative | All blood types | O- only |
| A Negative | A-, A+, AB-, AB+ | A-, O- |
| B Negative | B-, B+, AB-, AB+ | B-, O- |
| AB Negative | AB-, AB+ | AB-, A-, B-, O- |
Limbo of the Lost
Growing up you solve so many puzzles – picture puzzles, riddles, and word quizzes – so that your mind gets accustomed to questioning everything around you. This develops in you an inquisitive nature and you start to see mysteries in everyday things around you. You try to question the existence of some things and the non-existence of others. In this world full of mysteries, one such mystery is that of the Bermuda Triangle.
Also known as the Devil’s Triangle, the Bermuda Triangle is a section of the Atlantic Ocean, roughly bounded by Miami, Bermuda, and Puerto Rico. Mythical literature revels in the stories of ghost ships, of airplanes disappearing forever, and of instruments going haywire around the Bermuda Triangle. But these are just fanciful theories; there is no solid proof that these types of mysterious disappearances occur less in the other well-traveled sections of the ocean than they do in the Bermuda Triangle. As a matter of fact, there are many people who navigate the Bermuda Triangle on a daily basis without any incident. So why do we still think of Bermuda Triangle as an unsolved mystery?
Covering about 500,000 square miles of the ocean, the area was sailed through by Christopher Columbus on his first voyage. He reported that a great flame of fire crashed into the sea which was probably a meteor. Also, his observations about the erratic compass readings could be explained by the fact that at that time a sliver of the Bermuda Triangle was one of the few places on earth where the true north and the magnetic north aligned together.
Reports of unexplained disappearances started capturing people’s interest around the early twentieth century when the USS Cyclops, a 542-meter long navy ship with 300 men and thousands of ton of manganese onboard, sank somewhere between Barbados and the Chesapeake Bay in 1918. Although they were equipped to do so, the Cyclops never sent an SOS distress call and the extensive search yielded no wreckage.
After that, an alleged pattern started to form when five navy bombers carrying 14 got severely lost in the area in 1945. The nave bombers were forced to ditch at sea when they ran low on fuel. A rescue plane with 13 men also disappeared while searching for them. Even a weeks-long investigation failed to turn up any evidence.
In a 1946 magazine article, author Vincent Gaddis coined the phrase “Bermuda Triangle” for the first time after which it became a sensational legend with reports of planes going down despite having just sent “all’s well” messages. Paranormal writers blamed the triangle’s lethality on everything from aliens and Atlantis to time warps and reverse gravity fields while scientific theories, on the other hand, pointed to magnetic anomalies, waterspouts, and methane gas eruptions from the ocean floor.
In all probability, however, many don’t recognize the Bermuda Triangle as a hazardous place. There is no single theory that solves the mystery but there has been nothing discovered indicating the casualties were a result of anything other than physical harm. No extraordinary factors have ever been identified.

Dear- Indian education system…
Dear Indian Education System… I have decided to take a huge step, But, before that, you guys need to know a lot of things about me. I used to score amazing till std 10th when I scored well, leave alone my parents, all my friends, neighbors, shopkeepers… Even the watchman of my building started to say ” You are going to take Science. You will be an engineer” no. Don’t get me wrong. I don’t dislike Science. Science is beautiful science is the ultimate truth but when I came in Std 10th the half-interested teachers in my school and coaching institute didn’t teach Science at all! All they taught was how to solve maximum number of MCQs in a given time, like a robot that killed the beauty of Science sir. And that Physic’s topper of my class He didn’t believe that evolution actually happened He just wanted to solve maximum number of MCQs So much obsession with Science.
India hasn’t won a single Nobel Prize in Science Since Independence Nobel Prizes are just “awards” , you’ll say India produces the maximum number of engineers per year Yet, India ranks 60th in the Global Innovation Index that means no major innovation has happened since Independence, all we keep saying is “Aryabhatta invented Zero” to be honest, after 10th, I wanted to study Physics, Graphic Designing, Coding, History, Music and English Literature Why couldn’t the evaluation of my intelligence and calibers be on the basis of these subjects? Why should’ve I wasted my time studying subjects I didn’t want to study? So, I left the damn coaching institute, used to get out of my home during coaching hours and used to read novels in the park, see new places to be honest, I felt free It felt good not to be a zombie I learnt graphic designing on my own I listened to some beautiful music by Mozart and Rahman I read Poetry, I taught myself Python, and I read some amazing write-ups on various topics of Physics I am taking a huge step. I am dropping out no not because Steve Jobs, Bill Gates and Mark Zuckerberg are drop-outs, not because being a “dropout” is cool, and neither it is because of the frustration of failing.
Dear Indian Education System I am dropping out simply because you do not make any sense and now, you’ll ask me, who will give me a job? Who will feed me? I believe somewhere somebody is there who’ll see my skills. Will value my creativity. Who will value my intelligence, not my CGPA Yes, I failed. but I know there is a lot to do, observe, and learn only my marksheet says that I can’t do anything but I know I will do something good.

Horoscope Hysteria
Most of us have a habit of checking our monthly or weekly horoscope, we blindly submit to the predictions it states and it can become a cause of fear and tension or happiness and excitement. To be frank many of us strongly feel our fate lies in the words of the weekly horoscopes but that is not true at all. We have even gone our way ahead and done our own bit of research when it comes to horoscopes, zodiac signs and predictions. We might have even checked our sun signs and its personality traits so that we can counter check if it relates with ourselves. Many social media sites are filled with horoscope content and sun sign predictions e.g. – Instagram has many pages offering you an insight into this interesting world. We have even gone our way ahead and downloaded many horoscope applications like “Timepassages” or “Horoscoper Club” to keep ourselves updated.
Most of us have bought jewellery and other products with our respective sun signs, we also tend to go about and ask our partners about their birth dates to see how compatible we could be according to our horoscopes, we even judge peoples’ personalities based on their sun signs. Even though technology is grabbing us by its hands our belief in spirituality is getting stronger day by day.
Even though we say that this generation of millennials is quite open minded and believes in a free and liberated world but we still have a spiritual side to us which loosens us up and it allows us to un-clench ourselves.
For many astrologers horoscope reading has now even become an online business via video or phone calls, or blogs or sites and they are minting a good amount.
In this world filled with hurdles and unforeseen events we are quite keen to know the unpredictable events or all the wonderful surprises which are lined up for us in the coming future and this is one of the main points which attracts us towards Horoscopes. We tend to abide to the horoscope and believe in the prophecies frantically.
Many people believe astrology will give you a glimpse of how one’s day/week would be ahead, many people even adjust themselves according to their respective horoscope data, be it love life, financial woes or family problems or public and personal relations we feel the horoscope actually tells us about our future. But the question is “is it true after all”.
But many a times negative horoscope readings fill us with anxiety and fury, many scientists say there is no scientific validity behind horoscope predictions, many denigrate the belief in horoscopes as there is no strong underlying proof about the validity of data it has to offer us.
Most of us impetuously believe in the personality traits which the apps and other sites state under the respective zodiac signs and they can form many stereotypes in our working minds. One of the reason we follow horoscopes so diligently is because from old times it’s been the path to know many signs and according to many experts the data it predicts based on the position of the sun, moon and earth is quite accurate.
Horoscope and their predictions according to many are true and according to many are just invalid, but most of us definitely will continue looking forward to their predictions.

Businesses that are majorly affected!!!
In the pandemic situation where the world seeks a miracle of vaccines, there are many business that came to halt or even they are going to be shut soon. Currently the major task of ours is to stop the spreading of corona virus. It is wisely said “If there is Health there is Wealth”. First we need to cope up with the pandemic situation and then business can be again built, if we stay alive.
CNBC Global CFO survey says that 40% of the business are facing the problem in transportation of the goods and it is expected that it would take more 5-6 months to start and run normally (25% of them said 6 months and other would take a long than that).
“Nobody knows. The economic issues are totally driven by public health issues. You tell me how long we will be at home and I will tell you how long it will take for the economy and supply chains to recover.”
-words of Yossi Sheffi, Professor at Massachusetts Institute of Technology and the director of the MIT Center for Transportation and Logistics. Yossi Sheffi further says, if we want to build our business again as soon as possible than there is only one way out to do this and that is to join the war again corona virus and defeat it as early as possible, this epic war is started by many of the companies with their different types of help they can provide, like wise:
- Auto manufacturers like Tesla and GM motors are providing ventilators to the hospital.
(Image source: LosAngelesTimes)
- Apple and Facebook are the largest in supplying protective mask in the U.S.
- HanesBrands in contract with US federal government has decided to make cotton mask when the use of N-95 mask will be minimum. They decided to make 1.5 million mask weekly, and further if needed can go upto 5-6 million mask per week.
The supply chain is completely disturb there is over manufacturing as there is no one to load and unload the trucks. Border shipping is still allowed but shipping through overseas it still a major concern. There will be also huge disturb in supply chain of for pre-planned Indian weddings, as now weddings are postponed or might be done in simple way, the business related to it like party plots, wedding photographers, ca tress, decorators, wedding materials, transportation, apparels and even small-small business related to it. A single event covers many business so all the business are affected largely.
The business of theater and restaurant are also at halt, which may cause a major set back as there are many of the workers working in restaurant it self. In film industry too many of the workers are engaged.
The Science Of Developing Self-Control In Life
What is Self-Control and Why Does It Matter in Life?
Self-control consists of two components, namely, our ability to resist temptations and exercise control over our emotions and behavior.
To me, self-control is one of the most important things in life. Without it, I wouldn’t even write this article. Let’s face it, when you share anything on the internet that gets enough views, you always get a bunch of hate. Every time that happens, I feel like quitting. But I also realize that there are people who find these articles useful.
Self-control is what keeps me level-headed. It makes me resist my temptation to get pissed off and walk away. There’s also scientific proof that self-control matters in life.
“We rely constantly on self-control in every aspect of our lives. Although it is not an ability unique to humans, our elevated levels of self-control may have played a key role in our evolution. Self-control is likely to have been key to many of the traits such as prosociality, that define modern humans.”-Dr. Penny Spikins.
Self-Control in Daily Life
Most of us want to have a fulfilling career, vibrant social life, good relationships with our loved ones, and be in good physical shape. Here’s the thing: We need self-control to make those good things happen. Let me give you a few examples of what that looks like in daily life.
Eating Healthy
I stumbled upon this question on internet and books : “Why is it hard to eat healthy?” The top answer bluntly says, “You lack self control.” That made me laugh because it’s the truth. But we all know that it’s not that simple.
Eating healthy is a problem for many reasons. For example, most of us see food as pleasure—not fuel. In developed countries, we don’t have to worry about getting access to food for our survival.
But your body still has the natural urge to take advantage of food when it’s available. On top of that, there are many biological processes going on that we’re not aware of.
In my experience, eating healthy has nothing to do with your ability to resist buying junk food or ordering a pizza—it has everything to do with how much you educate yourself about your body. That’s an important reason why eating healthy is difficult: We lack the self-control to learn about nutrition, longevity, and how our bodies function.
Self Improvement
Why is it so difficult to improve yourself? Every day, we have the choice to do something that pays off later instead of now. Going to the beach, binge-watching tv shows, reading gossip, drinking alcohol, smoking, or every other pleasurable activity in life always gives you an instant payoff.
That’s why people often say, “Adapt or die.” If you don’t move forward, everything that’s related to you as a human will deteriorate. That’s a scary outlook. But here’s the problem: The degree of deterioration is so small that we don’t notice anything on a day-to-day basis.
You probably feel the same as yesterday, correct? Entropy in humans works over a longer period. That’s why we feel no urgency to improve ourselves today. We need self-control to invest in ourselves despite seeing a lack of daily improvement.
How to Develop More Self-Control
How can we get some? Based on everything you’ve read until now, let me share three things you can do.
1. Direct Your Energy Towards a Useful Pursuit
Our pursuit must be useful to make it stick. Shallow pursuits that only fulfill your materialistic desires will not motivate you to control your urges. You need something that’s so important you’re willing to do whatever it takes.
When I started my blog, I was dedicated to sharing honest advice without hidden intentions. To me, that was a worthy pursuit. That drove me to write every single day. As of this writing, I’ve published 331 articles on my site.
2. Set Long-Term Goals
On a day to day basis, I rely on a system that keeps me productive. A system is a combination of productivity strategies that help you to stay consistent.
But when it comes to long-term drive, I love to set goals because they will give you a clear sense of direction. In what direction do you want to take your life over the next three, five, ten, and twenty years? This is a very hard thought-experiment if you take it seriously.
Most people say, “I don’t know.” But you shouldn’t let yourself off the hook like that. Practice self-control by forcing yourself to pick a direction in life. You can always adjust. The long-term goals I set for myself five years ago have changed today. But at least they got me moving.
3. Minimize Stress
There’s some evidence that stress sabotages self-control.7 When you’ve had a stressful moment at work, it’s tempting to grab a candy bar (or two) to release the stress, right?
The same analogy is true for every other stress-related behavior. If you examine your life, you’ll find that you do a lot of things to simply manage stress. In fact, I believe that for most of us, that’s all that we do.
When I lived a stressful life years ago, I was only thinking about ways to get rid of that stress. But you’re only treating the symptoms that way. You can take as many vacations or buy as much crap you want from the internet, none of it will relieve your stress. If you truly want to minimize stress, you must design your life in a way that gives you a stress-level you can handle.
For me, that meant doing different work and leaving city life (I was living in London at the time). Some situations simply give us too much stress. A bad relationship is another common cause of stress. Unfortunately, there are no simple “step-by-step” tips for managing stress.
Sure, you can meditate, take long walks, read, or journal—all these things will lower stress—but there’s nothing better than designing a life that causes less excessive stress. But that doesn’t mean we should avoid all stress.
An optimal level of stress is actually great for us and it will slow down entropy. We need to find out what that level is for ourselves. Every person has a different stress tolerance. The key is to improve our self awareness and understand what stresses us out. Then, we want to lower that to a level that we can handle without getting frustrated.
Conclusion
Let me repeat the definition of self-control again: Our ability to resist temptations and exercise control over our emotions and behavior.
These two aspects will increase the quality of our decisions and therefore, our lives. I hope that all of this inspires you to strengthen your self-control. Directing your energy towards a useful pursuit, setting long-term goals, and minimizing stress are all good ways to set yourself up for more self-control.
Strengthening self-control is one of those things that has no end goal. It’s a never-ending process that will only benefit us the more we master it. When’s the last time you heard, “That person has too much self-control?” Exactly. More is better.
Will India have SUPERPOWERS like USA?
The world is almost ruled by powerful countries like USA, China, Japan, Russia etc. and its none of the wonder that developed countries are helping as well as exploiting the developing countries. Developing countries like India, Pakistan, Srilanka and many more… are mostly dependent on the developed countries, but the biggest question arises will India be list of the superpower countries by 2050. The answer would be yes, but unfortunately due to pandemic situation that number will rise to 2055-2060 because India faced a major setback due to this and also India build a strong relation with other countries with help of our respected Prime Minister sir. Let us look out which factors are going to help to build a nation with superpowers:
1- Economic growth
Chinese economy is based on foreign investment, while India is growing based on a more local economic sector. So if we look in future i.e. after 30-40 India will overtake as it is very slow process. We know very well that many MNCs have begun to invest tremendously in India and has started to rely on Indian engineers for their next generation products. Companies like GM, Boeing, Motorola and many others have begun to build their Research and Development facilities and Asian headquarters in India. They see more potential on Indian market. If India is able to maintain this steady growth, it can definitely become 2nd largest economy by 2050.
3) Military power
India stands on 4th rank in terms of defense with the budget of 54 billion $ and 13L+ army man. India has a total of 2,102 aircrafts and a naval strength of 295 and is ready to tackle any military emergency. India is gaining new technology and ideas from world and also our DRDO is working very efficient like wise India adopted 5th generation fighter plane from Russia and Defense Drone technology from USA and other technology too from Israel. Therefore if India increases the defense budget in next 3-4 decades, specially in Air force and cyber and New technology than India definitely can handle any worse situation.

4) Population
India has highest number of fresh minds, they are handled correctly with innovative and interesting education system than none of the country can stop India to be listed in top 5 countries. Youth is the biggest asset of India and no other country has this much amount of youth in their population. In the coming years, some of the strong nations of the world will face problem of decrease in populations and this will lead to, a decline in workforce, India will face no such problem.
India’s education system need to be modified a bit and student instead of memorizing theories, they should be taught to learn and understand the concept. The subject related to entrepreneurship should be added at early age so that they get knowledge of business at early age which would help them and ultimately help the nation.

Our scientist proved that India can even complete the mission on a budget of bollywood movie. India is also 4th country to land on the moon. India is emerging slowly in the field of software and will create a great impact in the near future.
BASICS OF A MICROBIOLOGY LAB
Microbiology is the study of microbes i.e. the organisms which we can’t see with the naked eyes. Although many microorganisms are beneficial for the human use, some are pathogenic also which causes diseases. Clinical Microbiological Laboratory is concerned with finding of those infectious, pathogenic microbes.
MATERIALS USED IN MICROBIOLOGY LAB
Laminar flow hood, Incubator, Autoclave, Refrigerator, Bunsen Burner, Wire loop, Petri plates, Glass slides, Weighing balance, Media plates, Sensitivity disks, Staining rack, Microscope, Bio safety Cabinet, Centrifuge etc.
INTRODUCTION TO DIFFERENT MEDIA
Some of the media used in the microbiology lab are :
- MacCONKEY AGAR : It is the selective and differential media used for the isolation of Gram-negative Bacteria. This media can be used for differentiating Lactose fermenting and Non-lactose fermenting bacteria.
- BLOOD AGAR : It is the enriched media for the growth of bacteria such as streptococci.
- CHOCOLATE AGAR : It is the lysed Blood Agar. The only difference in blood agar and chocolate agar is that in blood agar RBCs are lysed. This enriched media is suitable for the growth of bacteria that are unable to grow on Blood Agar.
- THIOSULFATE CITRATE BILE SALT AGAR (TCBS) : It is the selective as well as differential media for the growth of vibrio cholerae , a causative organism for cholera.
GRAM STAINING
Gram staining is the process for differentiating Gram positive and Gram negative bacteria. When the whole procedure of gram stain is followed and the slide is observed under the microscope, Gram positive bacteria appear Violet in color and Gram negative bacteria appear Pink in color.
For the gram staining we need Glass slide, Normal Saline, Inoculating loop, Bunsen burner, Crystal Violet, Gram’s Iodine, Acetone, Safranine.
PROCESS :
- The isolated colony of the microorganism is taken and in the drop of normal saline on the glass slide the colony is mixed with the help of inoculating loop to make a smear. The prepared smear is heat fixed.
- A staining rack is taken and on the smear, Crystal Violet is added. After 1 minute, the stain was removed by washing the slide in running water.
- After that, Gram’s Iodine is added on the smear as a decolorizing agent which is again washed after 1 minute under the running tap water.
- The next step is to add Acetone on the smear which is added in the hand to hand process.
- After the decolorisation is done, Safranine is added on the smear which is also washed after 1 minute.
- The glass slide is then air dried and observed under the microscope.
RESULTS :
It was observed under the microscope that the Gram positive bacteria appear Violet in color due to Crystal Violet stain whereas Gram negative bacteria appear Pink in color due to safranine.
TESTS ANALYZED
The tests analyzed in the microbiology section of the laboratory are basically the culture and sensitivities tests of urine, stool, sputum, pus swab etc.
The basic procedure of performing all the tests are :
- First of all, all the tests are performed inside the laminar flow hood.
- The samples collected from the patients and the media plates are kept inside the laminar flow.
- The inoculating wire loop is heat sterilized and with the help of it, the samples are cultured or streaked on the media plates.
- After inoculation, the cultured media plates are incubated for 24 hours (48 hours if necessary) for allowing the growth of bacteria.
- After the growth, staining is done or sensitivities are checked according to the requirement by the doctor.
- The report is prepared for the patient.
Master plan of China- DISCLOSED!!!
The life after the pandemic situation will not be normal again as this pandemic situation is also not normal.
Knowingly or unknowingly the virus developed in China (according to news) created the biggest impact in the health and economic sector of the world. Nobody knows how much time will it take to come out completely from this pandemic situation. China with the most power in terms of technology and population might have a master plan to be executed in the name of Novel Corona virus by supplying the goods of medical department and further other essential commodities which might be needed by the people in the near future to the world and soon they will earn billions of dollar by supplying it to the world. So, again now world will depend more on China than before.
We as a responsible citizen of India, need to stop the master plan of China as in the near future it will harm us very very badly. Let us understand by an example, India is surrounded by countries like Pakistan, Bangladesh, Sri lanka, Nepal this all countries have taken huge amount of money from China like wise Pakistan took huge money from China to develop a road passing from the mountain, so now Pakistan is in debt to pay the money and in return China can do anything to gain the money back. Pakistan took more money from China than from IMF, and has to pay around 19 billion US$, which will be extremely hard for Pakistan. In the same way Sri lanka owes 1.4 billion US$ which is left over from from 99 years and now China will ask for payback or will capture the Sri lanka. Bangladesh debt for 64.9 billion US$. India is also in debt of paying to China, but China will not capture India first it will first capture our surrounding countries and than head towards India. So, we need to become very attentive towards each step of China and understand their activity, we also need to stop buying Chinese goods to save our country and instead go for Made In India goods.

HEMATOLOGY
Hematology is a branch of medicine concerned with the cause, prognosis, treatment, and prevention of diseases related to blood. Some of the tests carried out in this section are PCV, CBC, ESR, ABO blood grouping, Antigen typing, Cross Matching etc..
MATERIALS USED IN HEMATOLOGY
Pipette, Haematocrit centrifuge machine for PCV, Haematocrit reader for PCV, Hematology analyzer for CBC, Microscope, Glass Slides, Electrophoresis Machine, Cover slips, Bunsen Burner, Capillary Tubes, Test Tubes, EDTA, Scissors, Normal Saline, Immersion Oil etc…
COMPLETE BLOOD COUNT (CBC) TEST
Complete Blood Count, CBC is a very common and easy test to determine the total number of different cells present in the patient’s blood. A doctor may order CBC as a normal routine test or if you have an unexplained symptoms of bleeding.
For the test, Blood Sample is collected in the EDTA bottle and is mixed properly with the anticoagulant.
The main equipment used for the CBC test is HEMATOLOGY ANALYZER. The EDTA bottles are put under the hematology analyzer sensitive probe so that the machine can analyze the samples and give the appropriate results.
PACKED VOLUME (PCV) TEST
It is also known as Hematocrit Test. PCV test is a measurement of percentage of blood that is made up of cells. The test value is expressed in percentage. For eg, if the PCV value comes out to be 30% then it means that there are 30ml of cells present in 100ml of blood. The doctor may order for the test if he finds the symptoms related to Anaemia, Polycythaemia or dehydration. The value of PCV rises when the number of RBCs increases or when the total blood volume is reduced.
Reference values:
Newborn infants – 50 – 70%,
Newborn at one week of age – 37 – 49%,
Infant at three month of age – 30 – 36%,
Infant at one year of age – 28 – 45%,
Child at ten years of age – 36 – 40%,
Adult female – 36 – 46%,
Adult male – 38 – 50%
ERYTHROCYTE SEDIMENTATION RATE (ESR)
It is a test that directly or indirectly tests the inflammation in the body. It also measures the rate at which erythrocytes present in the blood sediments. In the test, blood sample is collected by the patient in the EDTA tube and the rate at which RBCs settle down at bottom is measured.
The followings are considered normal ESR test results:
• Women under age 50 : >20mm/hr
• Men under age 50 : >15mm/hr
• Women over age 50 : >30mm/hr
• Men over age 50 : >20mm/hr
• Newborns : >2mm/hr
BLOOD GROUPING TEST
Blood Grouping, generally known as ABO Blood grouping is a test which can determine the patient’s blood group. The blood group of a patient may be A, B, O or AB type. Three different types of serum are used in this test i.e. Anti-A, Anti-B, Anti-D.
In the test, Blood samples are collected from the patient in the EDTA bottle. A sterile glass slide is taken and was labeled as A,B and D. Blood drops were put on the slide in the three different regions. Anti-A , Anti-B and Anti-D serums were added to the blood on the slide at the respective regions and mixed with a toothpick. Agglutination was observed after some time and results were recorded.
Is the ocean is safe nowadays?
As we all know that the whole earth is divided into two parts land and ocean, on earth around 70.9% of the water, and only 29.1% of the land. however, the ocean gives many things and it means a lot to us, it gives water, food, medicine, and the least goes on. the human also takes advantage of it.
However, nowadays the ocean is in danger because of the pollution and human traffic in the water, big industry and factories also omit their chemicals and wast, due to these the marine life are in danger and some spices are in endanger and many times the oil ship crash in the middle of the ocean and because of the oil spill, the fishes and other creatures do not breath properly and lost there life. many oil industry also plant their plants in the middle of the ocean and because of carelessness these happened,
However, the prestige oil spill happened near the coastline of Galicia, Spain. this was caused by the sinking of the 26-year-old ship in November 2002, which was carried around 70,000 tons of heavy fuel and this accident happened because of heavy Strome. Due to this accident,
The area was totally covered with dead oil-coated coral reefs and many species of sharks and birds, and the fishing industry. but the government also took action to save the ocean and many organization also support and pay the fund to the government, within a two week the ocean was clean and look great as it was.
furthermore, we celebrate world oceans day every year on 8 June, what do you know about this day?
this concept of the day firstly proposed by Canada’s international center for oven development and the ocean institute of Canada in 1992 at the earth summit, and this conformance regarding environment and development held in Rio De Janeiro in Brazil. the day marked in a variety of ways, including launching new campaigns and initiatives, special events at aquariums, and 2005. On that day, people celebrate by cleaning water, beaches, and feeding food to the ocean animals, hence famous influencers and celebrities give a speech on social media and share short movies regarding ocean life on the silver screen, because of this people nowadays, are more aware compared to the past.
in years between 2002 to 2008 dozens of things happened like the first-ever website launched “www.worldoceanday.org”, to promote and give guidance to the people, who wont to do something to make ocean pollution-free and they also share the timeline and events happened around the world, and in 2004 the ocean project launched by the united nation to officially recognization 8 June as world ocean day, in 2008 united nation also made lows to reduce the pollution in the ocean.
we should take steps against those people who pollute the mother nature and we stop them or complain in government departments regarding their work and actions, and the government also take down those industries which spread chemicals in the water.
“There’s nothing more beautiful than the way the ocean refuses to stop kissing the shoreline, no matter how many times it’s sent away.”
Worlds first “Internet controlled robot” By 23 year old Indian boy : Covid-19
A 23 year old Thane engineer has developed worlds first-of-its-kind internet controlled robot which can be used to treat covid patients in hospitals.
The robot delivers food, water, beverages, medicines and even some good advices to the patients without the help of any hospital nurses or staffs.
“This aCoro-bot’ eliminates the need of physical presence or contact of nurses or ward boys with the patient. It can deliver food, water, medicines and interact with the patients through a camera. Through a speaker, it can also advise patients on various precautions like sanitizing their hands before picking up anything from the robotic tray,” Says Pratik tirodkar the creator and designer of this robot.
This smart boy is also the founder of a start up ‘PNT solutions’. Whatsmore this young lad had developed other unique creations when he had barely stepped to college. This include world’s first ‘Humanoid’ with 47 body (axis) movements, a robotic bird ornithopter for various outdoor applicationsapplications, a mini packaging robot and several others.
This genius has even given over a 100 guest lectures to the brain students of IITs and NITs in the country.
This robot can be operated from any part of the world through internet. The robot comes with 3 trays with a carrying capacity of 10-15 kg each, plus a 30-kg storage at the bottom, enabling it to serve the supplies to over a dozen patients at a time in the COVID-19 ward.
“There are separate dispensers for water, tea, coffee, besides sensors for sanitizers which flow out quickly when the patient holds his hand below it and cuts off the supply when the hand is removed. Thus there is minimum wastage,” Tirodkar explained.
“Not only the COVID-19 patients, Coro-bot can also take care of itself. It has three nozzles at the back to give itself a disinfectant bath regularly, it goes on spraying sanitisers on both sides of the path, plus disinfects the ground it moves on by using UV lights” Says the genius.
The Coro-bot also has LED lights illumination to make it convenient for night usage as well, timers for indicating lunch-dinner, emergency button, besides a small PC like screen on the top for basic computer work or entertainment, he said.
This is now successfully deployed at Holy Cross Hospital in kalyan. Impressed by this robot over a dozen of other hospitals have ordered coro-bot in Mumbai.
“The Coro-bot costs between Rs 1.60-Rs.3.80 lakhs, depending on various specifications like the load-carrying capacity, etc, and the Ornithopter is around Rs 30,000. I have a small manufacturing unit at Dombivali, but if I can get a good investor, I can get into mass production,” he said.
Pratik tirodkar is currently doing his Btech in instrumentation engineering from Bharati Vidyapeeth College of Engineering, Navi Mumbai.
