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.

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 the motion of the ball. The air is flowing on both sides (right and left) of the ball and trying to slow it down.
On one side, the air is moving in the opposite direction of the ball’s spin causing increased pressure, while on the other side, the air is moving in the same direction of the ball’s spin, creating an area of low pressure.
This difference in pressure makes the ball curve towards lower pressure zone. This is the reason why football traces a curved path into the net, when kicked.
This technique looks really cool, you should really give a try and spectators will cheer you-‘’LOVELY BRO’’.
