As we start celebrating the International Year of Chemistry, let's think about chemistry and beauty. What makes an experiment beautiful? Does it have to be clever, or prove something unbelievable? And which is the most beautiful of them all?
Today, when you have an illness, you have to take medicine in several doses, as pills or syrups. Imagine a day when you have to take the drug only once, and it works a whole lot better. Nanotechnology can help do that.
Imagine you're an electron on a motorcycle, zooming along on a smooth, empty road. No speed breakers or potholes to stop you. In an instant, you've reached your destination. Well, for an electron, such a road is called a superconductor.
Did you know that just one-thousandth of the sun's light that reaches the earth could satisfy all of humanity's energy nine times over? What if we capture this energy cheaply? Perhaps, artificial leaves are the answer?
Today, we rely on carbon-based fuels for almost all our energy needs. Coal is used for electricity and petroleum products for moving vehicles. But these cause pollution and global warming. Many scientists and economists have suggested moving to a hydrogen-based economy.
We've heard scientists telling us that global warming is causing the ice in Antarctica and the Arctic Ocean to melt. Did you know that these ice sheets hold some secret stories in them? It's the story of how our earth's atmosphere changed over many millions of years!
The 19th century was a turning point in India's history, with many new technologies introduced by the British. Inspired, some Indians wished that our country too should be at the forefront of discovery. That's how India's oldest scientific research institute started.
