Professor Geraint Lewis, astrophysicist at University of Sydney, takes up the challenge to explain a proposed theory of everything in the time it takes to ride an elevator from ground floor to penthouse.
Bitcoin and Blockchain. You've heard of them. But what do the words actually mean? Can you define blockchain? We've challenged a computer science expert to do just that, in the time it takes to ride an elevator.
What happened before the big bang? How can something come from nothing? We've challenged a physicist to explain the origins of our universe in one elevator ride. Good luck Dr Julian Berengut, from University of NSW.
What is infinity? What's the opposite of infinity? Mathematician Dr Sophie Calabretto tries to explain it in three minutes.
Memory is crucial to survival. But do we even know, what memory is? Rad challenges neuroscientist, Dr Yee Lian Chew, to explain in an elevator ride.
How does our brain shape our entire perspective of the world? Neuroscientist, Dr Sarah McKay, does her best to explain in an elevator ride.
Like most of us, Rad Yeo finds quantum physics pretty difficult to wrap her head around. So she's invited quantum engineer Dr Andrea Morello to demystify the topic and explain how it affects us, in this elevator pitch.
Our universe has been expanding ever since it was created. But what's causing this, and will it continue forever? Rad Yeo challenges astrophysicist Professor Tara Murphy to tackle this cosmic question in this elevator ride.
Why do astronauts on the International Space Station age more slowly than us here on the ground? Rad Yeo gives astrophysicist Dr Devika Kamath two Earth minutes to untangle the science.
