Summary

Is the kitchen home to some of the most extraordinary technology humans have ever invented? Professor Hannah Fry and Michael Stevens explore the science of everyday appliances, from the strange physics of coldness to the wartime origins of the microwave. They explore how humanity learned to trap 'coolth', beam heat into leftovers, and turn the most ordinary room in the house into a high performance laboratory! From ice merchants and exploding eggs to magnetrons and magnetic fridges, this is the surprising story of the science hiding in plain sight. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Hello and welcome to The Rest is Science. I'm Michael Stevens.

0:04.3

And I'm Anna Frye. Michael, what is your favorite room in the house and why is the answer to the kitchen?

0:09.1

Oh my gosh, we're jumping right in. My answer has to be The Kitchen. Is this a setup for your episode?

0:13.3

It's the correct answer.

0:15.2

Okay, I want to tell the audience, this is an episode where Hannah has come to talk to me about something that is, dare I almost say, annoyingly close to her heart. Before we record episodes, she's always talking about refrigerators. And I'm like, Hannah, one of these days. One of these days, my time will come. Get it out of your system. My time will come. No, I'm really excited to hear this. And of course, my favorite room in the house is the kitchen. If that's going to help move things forward. I'm not, see, this is the thing. I've managed to, I've managed to expand from not just my love of fridges, but I'm going to do other other household items in the kitchen too, Michael. This is, this is going to be a little justification as to why the kitchen is the room that

contains all of the most interesting, high-performance scientific equipment in your house.

This episode is brought to you by Cancer Research UK. If you wanted to type out the entire human genome, you would have to type at 60 words a minute

1:17.4

for eight hours a day for about 50 years. Okay, that's the scale of the DNA rulebook inside

1:24.7

each one of your cells, telling it when to grow, when to divide, and when to

1:29.5

stop.

1:30.0

And different tissues read that same rulebook in different ways.

1:33.0

So a skin cell doesn't behave like a lung cell.

1:36.1

And cancer can begin when those instructions change.

1:39.5

Not one dramatic moment, but through small, gradual edits over time.

1:44.6

Now, cancer isn't one disease. It is more than 200 types shaped by where those changes to the

1:51.3

rulebook happen and how cells respond.

1:54.5

Cancer Research UK is the world's largest charitable funder of cancer research, backing studies

2:00.1

across all types of cancer.

2:02.2

Work that takes years of very careful, steady progress to deliver each breakthrough.
