Key Takeaways

  • Ice molecular structure: Water molecules form hydrogen bonds creating open crystalline structures where molecules stay farther apart than in liquid water, making ice less dense and causing it to float—a property critical for ocean ecosystems and climate regulation.
  • Multiple ice phases: Scientists have discovered twenty distinct ice forms (ice I through ice XX) that exist under different pressure and temperature conditions, including superionic black ice at hundreds of gigapascals that may exist inside Uranus and Neptune at thousands of degrees.
  • Arctic accessibility crisis: The North Pole became unreachable by surface travel after 2014 due to excessive open water from rapid ice loss, with the Arctic warming three times faster than anywhere else and likely becoming a commercial shipping route within thirty years.
  • Ice core climate data: The Beyond EPICA drilling project reached 2,800 meters depth in Antarctica, extracting air bubbles from ice over one million years old that reveal historical carbon dioxide levels and temperature patterns across multiple ice ages for climate analysis.

What It Covers

Scientists explore ice's unique molecular properties, from hydrogen bonding that makes it float to twenty different crystalline forms under pressure, plus how Arctic ice loss affects polar exploration and climate systems globally.

Notable Moment

A researcher discovered three new ice forms (ice XIII, XIV, XV) by accident when someone contaminated the lab water supply with acid, then spent months unable to replicate the discovery until realizing acid was the key catalyst.

But if you're in The UK, the full series is available right now, first on BBC Sounds. Hello. I'm Brian Cox. And I'm Robin Ince. And this is the Infinite Monkey Cage. Now Brian, as you can probably tell, is very much a natural ice skater, whereas I'm so naturally clumsy. I have so much entropy that just seems to be around me all the time. Why is it that I slip over on ice a lot more than you do from, like, kind of the perspective of physics? I reckon it's because your center of mass is in the wrong place. You've got to be fat. Red shifted. Red shifted. Alright then. Well, ice has, of course, is this is what we're gonna talk about today, and ice has played a major part in not merely science, but also science variety. Does anyone here know about the Iceman? Val Kilmer. It's not Val Kilmer. No. No Top Gun. Right? None of you heard about the Iceman. It's one of the greatest acts that ever used to be. A man would turn up to a comedy club with a block of ice, and his twenty minute routine was him trying to melt it before the time ran out, and then he would merely write down another failure and walk off with what remained of the ice. Has anybody actually heard of that? No. It's just They're making a movie about him and everything. But Iceman in Top Gun? Yeah. Yeah. Okay. So this is my first time here. Is this the show? Very unusually. Robin's rambling introduction is germane to today's show because today, we're talking about ice. At first sight, perhaps the simplest of substances, yet arguably the most complex crystalline solid known to exist in nature. To explore …
