Podcast: In the Hunt for Air That We Can Breathe

Consider this - the WHO says that "no threshold [of small particulate concentration] has been identified below which no damage to health is observed" and so, they've instead stated a guideline that aims to achieve the lowest possible PM concentration - this is 10 micrograms per cubic metre for PM 2.5. Delhi's is 15 times that much!

Podcast: Letting Nature Be - How A Woman Saved A Hill In Mussoorie

This episode of The Intersection brings the story of Sejal Worah, World Wildlife Foundation India's programme director, a woman who single-handedly revived the ecosystem of Mussoorie's Flag Hill.

Podcast: The Timekeepers Of India

Whether or not time was present before the Big Bang, it exists in our universe - we have simply invented a way to measure it, which is through seconds, hours and years. So, the question that then arises is who sets the time? This episode of The Intersection takes you to the National Physics Laboratory in New Delhi, to find out just that.

Podcast: The Science And Philosophy Of Pi

"Only two things are infinite, the universe and the human stupidity..." - that's how a popular quote by Albert Einstein starts. He forgot about one other infinite thing: pi, which is as important as the universe and as irrational as human stupidity. This episode of The Intersection takes a look into the many different aspects of pi and explains why this number is so important.

Podcast: Are We Heading To A Future In Which We Can Survive On Less Sleep?

For anyone who leads a hectic, urban life, the sheer lack of time is a common complaint. Meeting deadlines at work, everyday commuting and domestic chores often take a toll on our social lives and interests. "If only I had a few more hours in a day," is a sentiment that most of us can identify with. And some of us, who really ponder about how we can add more hours to our day, may start to wonder whether it's really worth spending a huge chunk of our day on sleep. This episode of The Intersection investigates that very idea - is it possible for us to sleep less and well?

Notes On The Intersection: Neutrinos

Physics works in a strange manner. In order to understand the mysteries and complexities of our vast universe, you often have to enter tiny underground holes to study matter. This is exactly what a group of scientists aim to do with the Indian-based Neutrino Observatory (INO). The observatory, first proposed in 2001, aims to study neutrinos, which are fundamental particles that we have a lot to find out about.
