Kunal Shah on productivity, life hacks and how India can become a successful nation 🔥🔥

By
 Kunal Shah on productivity, life hacks and how India can become a successful nation Kunal Shah is the founder of CRED. He is a fierce learner and has added layers of knowledge through his observation of the world and people. Here are few takeaways where he appeared on a podcast, on productivity and how India will become the superpower of the world. Try to meet more smart people to become smarter. Good people who want to learn all the time will naturally surround themselves with other people who want to learn all the time and that group compounds much faster. Our country will move forward where more people will take risks with their careers. More people taking risks with their careers will result in them creating careers for other people who don't want to take risks.  People who keep complaining about work-life balance either have a shitty life or a shitty job. Watching content, again and again, will not improve your life, taking actions will. Understand the value of time ...

How does a MRI machine work ? | The Science behind MRI

By
How does a MRI machine work ? | The Science behind MRI                       Hey guys in this article, we'll try understanding how a MRI machine works, how does a MRI machine detects and display images of parts of our body like brain etc.,    What is a MRI ?                      MRI stands for Magnetic Resonance Imaging , it is medical imaging technique used in radiology to create detailed images of organs and tissues inside our body.                MRI machine consists of mainly 3 components - the Magnet, Radiowaves and a Gradient . A computer is needed to display images.                  The tunnel that we see in the first image in which the patient is placed, is the magnet, that creates a strong magnetic field around the patient. The gradient (red color in the above fig) adjusts the...

Learning the way to learn | How to learn anything ?

By
Learning the way to learn | How to learn anything?   Many of us say that we know or have knowledge, whenever we are asked about the topic we are familiar with. But does that actually mean you have understood it well enough ? Hmm…           If a friend of yours, comes and asks you to explain about something, you might have told him what you know about the topic but couldn't have explained it clearly or you probably might have confused him even more…  Why does that happen ?  what is it indicating ? Is it indicating the lack of understanding about the topic in us ?   If you want to master something, teach it.                                                                          -Richard Feynman      The Feynman tec...

Why do stars twinkle ? 🌟 | Why don't planets twinkle ? 🤔

By
Why do stars twinkle ? | Why don't planets twinkle ?                "Twinkle ! Twinkle ! little star, how I wonder what you are?". This was something we all enjoyed singing as kids.             But today we will see whether stars actually twinkle or not.          Twinkling of stars is because of the atmosphere - a layer consisting of gases, ions, dust particles surrounding the earth. This atmosphere is responsible for 2 things - one is the twinkling of stars and if you were to look up at sky, point out to a star and say that's the position of the star... you are probably wrong. Let's understand this.           The presence of various gases, ions and dust particles in the atmosphere, makes the atmosphere more denser than vacuum and this density varies from place to place. If there is more oxygen or nitrogen at one place, it is more dense and if it is less at another...

Why are water droplets spherical in shape ? | Science In Nature 😇

By
Why are water droplets spherical in shape?         You probably might have enjoyed dancing during the rain & even after the rain stopped, you would enjoy the cool breeze & amidst that you observe that there are tiny water droplets present on leaves in your garden and if you were to go nearer to a leaf, you would be amazed to see the shape of droplet, its refracting nature. So today we are going to address one of our childhood questions - "Why water droplets are spherical in shape?". Note: To continue reading this article, you will need a little bit of patience, as we are going to deep dive into it  - from basics to addressing our question. So please take some time to read this article and you will surely enjoy the science behind it.                 There are number of water molecules inside water. Consider a water molecule inside the water beaker. It is surrounded by many other water molecules around it. This mol...

This is why trees will help fight climate change | Analysis

By
This is why  trees will help fight climate change | Analysis           "TREES"-the benefits of it is a long list right from providing clean air,food and medicines to stabilizing the soil to avoid erosion, it's an important resource to human life.            In this article, we'll know how trees are going to play a huge difference in combating climate change. Why importantly trees?            Trees live in contact with many microorganisms in soil. These include fungi that trees need to survive.When trees capture carbon from the atmosphere, much of that carbon enters the soil to feed these microorganisms which in turn help in building healthy soil that supports life and stores carbon for a long time. One of the major compounds responsible for climate change is carbon-di-oxide. By increasing the green cover, more carbon-di-oxide will be captured and thereby reducing it's amount in nature and ...

Why all airplane windows are round in shape ? 🤔

By
Why all airplane windows are round in shape?          The round windows in an airplane aren't a simple design choice. It's a life saving engineering innovation. If the airplane windows were square like the ones in your home, the whole plane would have disintegrated mid flight and no one wants to deal with any of that kind on their way.        To make planes suitable to fly at higher altitudes, it has to make some design changes. First, the cabin has to be pressurized so that passengers could breathe. Secondly, the cabin has to be given cylindrical shape so as to sustain the internal pressure.         After considering all this, we might think that it sounds to be a perfect plane. But wait. In mid 20th century, there happened to be three airplane crashes and the reason why it happened was because the engineers overlooked a flaw: The square window.         Now let us try to understand of why thi...

Thinking from First Principles - The Physics framework of thinking !! 🔥

By
First Principles - The Physics framework of thinking!!          "The Earth is flat". This is what people thought, because they could see people,vehicles, all moving in the horizontal direction, until science came and proved it wrong. Like this, in our day to day life, we start assuming things  to be true, that we observe or what people tell us, without thinking whether it is actually true or appearing to be. So how do we know the actual fact? Can we change the way we think? YES... we need to adopt the "First Principles Thinking" method. What is First Principles Thinking?   Why should we use it?         The first time I heard this was from SpaceX CEO, Elon Musk. First principles thinking  is a kind of physics way of looking at the world. It is basically boiling things down to the fundamental truths, that you know are true and reasoning from up there. In mathematics, it is known as an axiom. Normally, what people do i...

Why does a football trace a curved path into the net, when kicked?

By
  Why does a football trace a curved path into the net, when kicked?             You might have seen football players, like the most famous Christiano Ronaldo and Lionel Messi scoring some crazy and unbelievable goals. Usually, when they go for a free kick, you see that the path traced by the football is curved rather than straight or a linear path. Footballers use this technique to score incredible goals. Now let’s try to know the science behind it. The reason why football traces a curved path is due to an observable phenomenon called the  " MAGNUS EFFECT" , described first by German physicist Heinrich Gustav Magnus. This is a phenomenon observed not just in football but also in many other sports as well.               Let us try to understand it.         When the football is kicked, it starts moving forward and spins around its axis and the air flow provides opposition to th...
