Some of us have an interest and build the ability to crack math problems and puzzles. A few of us follow intuition and the rest use logic. Let us look at a few important thinking skills needed to solve complex cases through this series. Scroll through…
Building a fast train? Take inspiration from a bird that dives at great speeds and innovate…
This week we look at something that moves really fast – the bullet train! The Shinkansen bullet train in Japan can travel at over 320 kmph. Countries like Japan also have a restriction on noise levels apart from all the headache that you can get from going at high speeds.
When the train comes out of a tunnel, the air pressure is built up in waves and the nose emerging can produce a thunderclap heard from far away. In the 1990s, a bird-watcher and engineer Eiji Nakatsu, took inspiration from how the kingfisher smoothly darts into water to catch fish. He redesigned the nose of the train to resemble a 50 feet long steel kingfisher beak. It solved the noise problem, and also reduced the power consumption at greater speeds!

What makes a lizard carry its own weight along high walls and defy gravity? Understand the phenomenon behind super glue…
Let’s look at to our third inspiration – from geckos to super glue! To view the image, move the slider from the right hand side towards the left on the image.
Did you know that the idea for super glue comes from the gecko(lizard)? The feet of the gecko are covered with millions of microscopic hairs and in between these hairs is a field of attractive forces that makes it so strong that one single toe can carry eight times the weight of the gecko.
This phenomenon has been copied by scientists and they ended up creating super glue. Super glue can be used to glue objects over 1 kg onto smooth surfaces. It can be used to glue things in places where you can’t use wet glue such as in space! Spiderman might have wanted to discover this earlier!

It is a day we reflect on ourselves and our life. But what about this precious planet that sustains us all? Though we do not know Earth’s exact birthday, we do set aside a day in the year to slow down and appreciate this beautiful planet.
Remember, it is important to think of every day as Earth Day and not just celebrate one day in the year.
