we have four different drink receptacles.

which is part of a project on supercritical fluids,

Then you probably know I collect plastic water bottles

and Sam Tang just brought me this one from Hong Kong

Brady, who doesn't really like my water bottles, brought

me this one from San Francisco, where he films Numberphile

and if you turn it round, you can see it says

which I really quite like because it's got my surname,

Poliakov, on it, though it's not spelled quite the same way

Some of you may have seen our video on Vodka

Mendeleyev vodka and of course, Poliakov vodka

and a piece of tartaric acid from a Swiss wine barrel

[Dr. Holly Krieger]  ...this is known as the Mersenne Sequence.

Well people have heard of the Mersenne Sequence because this famous question that we don't know

how to answer is, "Are there infinitely many prime numbers in this sequence?"

Since this question is so hard, one  easier question we could ask would be,

"What do the prime divisors of each  element of this sequence look like?"

[Brady Haran] That seems like a harder question!

[Dr. Krieger, laughing] Well it might be a harder  question depending on how specific you want to get.
