Joe Interviews Brian Greene!

Wouldn’t it be cool if you could take courses in spacetime and relativity from a world-famous physicist? And instead of boring lectures, they used flashy animations and you could take the class at home and never put pants on?

This week, physicist Brian Greene launches World Science U, an ambitious new online education portal that he hopes will revolutionize the digital classroom. I sat down with him (on the internet) to talk about special relativity and spacetime (his first two course offerings), why visuals work so well for physics, and whether there’s a parallel universe where people already know all this stuff (spoiler: maybe).

We had a pretty awesome chat, and Dr. Greene answered some tough questions. I don’t want to spoil any more surprises. Just watch it already!

What is the most astounding fact you can share with us about the Universe?

Neil deGrasse Tyson, PhD: The most astounding fact… is the knowledge that the atoms that comprise life on Earth, the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars, the high mass ones among them went unstable in their later years they collapsed and then exploded scattering their enriched guts across the galaxy. Guts made of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself. These ingredients become part of gas cloud that condense, collapse, form the next generation of solar systems… stars with orbiting planets, and those planets now have the ingredients for life itself.

So that when I look up at the night sky and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us.

When I reflect on that fact, I look up – many people feel small because they’re small and the universe is big – but I feel big, because my atoms came from those stars. There’s a level of connectivity. That’s really what you want in life, you want to feel connected, you want to feel relevant, you want to feel like a participant in the goings-on of activities and events around you. That’s precisely what we are, just by being alive…
