Thread: Horizon Club v.Γ

1. Horizon Club v.Γ

Remember Utisz's BBC Horizon Club? I miss it.

I propose we start a Horizon Club v.Γ so we can hang out and discuss more pop science documentaries. Sound good?

2. I rather enjoyed this pair on energy, information and entropy.

3. I feel foppish and dandy already!

4. I watched the second video, very nice. These videos generally stick to the fundamentals. The encoding of the loom pattern is easy to comprehend even without knowing how the loom works, though that would help. Morse code is elegant and easy to understand though it must take a lot of practice to master picking out the letters as they come in. When he get's to Turing and Shannon and Landauer the concepts are more abstract and less explained.

Am I critiquing this? Sorry. Just the usual meta-ing observation that the complexity of modern concepts gets harder to really understand as you go along as the analogies and comparisons to everyday life start to fail me.

I took information theory in grad school - it was a very exciting concept that information was tied to probability. That was the first chapter of the book. The next seven just eluded me even though I got a B in the class as I recall.

I've studied Turing's paper based on some excellent book which I forgot the title of that was recommended here by Ferrus I believe. About half way through I started taking some statements on faith - which isn't really understanding is it? I'm still wondering whether the brain is super-Turing or not, no idea really.

The Landauer limit is new to me, nice! Landauer Principle

In a 2012 article published in Nature, a team of physicists from the Ecole Normale Supérieure de Lyon, University of Augsburg and the University of Kaiserslautern described that for the first time they have measured the tiny amount of heat released when an individual bit of data is erased
And that points to another thing I've never heard of before reversible computing.

I'm supposed to be educated in this stuff and I'm getting over run! Bring on the 22nd century education methods please.

Eh - how does one discuss these things in a way that doesn't sound autistic?

5. Eh, they are both closed now.

Solar neutrino problem.

6. ^^ will add to the queue!

It's okay, I kind of forgot about this thread after I created it. When I get back from Toronto I'll see if I can dig up some other links.

That was a nice pick-me-up. Thanks!

9. I dunno what to say.

This was good. I'm always more impressed by the engineering of things: scooping up three helium atoms out of a massive tank like that?

Found this one quite entertaining:
