Quantum Physics and Riemann's Hypothesis

Prime Numbers Get Hitched is an interesting little article about connections between Riemann's Hypothesis and Quantum Physics. It's a short on details though.

Be worried, be very worried

CNN has finally noticed:

Be worried, be very worried:
The climate is crashing, and global warming is to blame

No one can say exactly what it looks like when a planet takes ill, but it probably looks a lot like Earth.

Never mind what you've heard about global warming as a slow-motion emergency that would take decades to play out. Suddenly and unexpectedly, the crisis is upon us.

From heat waves to storms to floods to fires to massive glacial melts, the global climate seems to be crashing around us

...


I wonder when Fox News will do the same.

V For Vendetta

I watched V For Vendetta tonight at Cinerama. I liked it. (Enough to palliate the Wachowski brother's faux pas with the sequels to the Matrix).

It's kind of hard to describe though. In the near future, Britain is ruled by a totalitarian dictatorship. V is a masked figure, working to overthrow the government. The story is told from the perspective of Evey (Natalie Portman), who becomes entangled in V's plot.

Patenting Thoughts

For example, the human genome exists in every one of us, and is therefore our shared heritage and an undoubted fact of nature. Nevertheless 20 percent of the genome is now privately owned. The gene for diabetes is owned, and its owner has something to say about any research you do, and what it will cost you. The entire genome of the hepatitis C virus is owned by a biotech company. Royalty costs now influence the direction of research in basic diseases, and often even the testing for diseases. Such barriers to medical testing and research are not in the public interest. Do you want to be told by your doctor, "Oh, nobody studies your disease any more because the owner of the gene/enzyme/correlation has made it too expensive to do research?"

Michael Crichton has an editorial, This Essay Breaks the Law in the New York Times (via Slashdot). It addresses a patent case before the US Supreme Court that will decide whether thoughts and relationships are patentable.

Who Can Name The Bigger Number?

Who Can Name The Bigger Number? (via Metafilter).

...

Ackermann numbers are pretty big, but they’re not yet big enough. The quest for still bigger numbers takes us back to the formalists. After Ackermann demonstrated that ‘primitive recursive’ isn’t what we mean by ‘computable,’ the question still stood: what do we mean by ‘computable’? In 1936, Alonzo Church and Alan Turing independently answered this question. While Church answered using a logical formalism called the lambda calculus, Turing answered using an idealized computing machine—the Turing machine—that, in essence, is equivalent to every Compaq, Dell, Macintosh, and Cray in the modern world. Turing’s paper describing his machine, "On Computable Numbers," is rightly celebrated as the founding document of computer science.

...

"Very nice," you say (or perhaps you say, "not nice at all"). "But what does all this have to do with big numbers?" Aha! The connection wasn’t published until May of 1962. Then, in the Bell System Technical Journal, nestled between pragmatically-minded papers on "Multiport Structures" and "Waveguide Pressure Seals," appeared the modestly titled "On Non-Computable Functions" by Tibor Rado. In this paper, Rado introduced the biggest numbers anyone had ever imagined.

I miss 365.

Big Dipper

The Astronomy Picture of the Day has a nice photograph of the Big Dipper today.

White To Play And Win

From my game today:



52. Rd8! Re8+
53. Rxc8 Rxc8
54. d7 Rxc7
55. d8=Q+ Kg7
59. Qxc7 +-

[In fact, 53. Rxe8+ is also winning since after both 53...Kxe8 54. Bc6+ Kf8 55. d7 and 53...Rxe8 54. d7 White wins the rook and promotes a pawn too].

Canada

Website aims to educate Americans about Canada [Globe & Mail]:

Oh sure, you hear about how everyone plays hockey in Canada, gets to the rink by dogsled and then goes home to an igloo.

But many myths about Canadians that circulate in the United States aren't nearly so silly or harmless.

...


For the record, I don't own a dogsled or igloo (and, in fact, have never used either). Similarly, I don't know Jimmy, Sally, or Suzy.

Hockey is practically a religion though.

New Movies

Aside from Munich, I haven't been to a movie theatre in a while. There are few interesting-sounding movies coming out soon though: V for Vendetta, Thank You for Smoking, Tsotsi, Night Watch.

Funny Links



  • Real-Life Recreation of The Simpsons Intro (via Funkaoshi).


  • Calvin & Hobbes: Writer's Block


  • $39-Dollar Experiment (via Metafilter): I was sitting around one day, skimming through a pile of bills that I needed to pay. I looked over at a new, unopened roll of stamps that I had sitting in front of me, and I thought to myself, "$39... for a roll of stamps? Geez... You can't get much for $39 nowadays. Or can you...?" ... I decided I was going to try something — I was going to take my roll of stamps and send 100 letters to 100 different companies, asking for free stuff.

    For example,

    Dear Sir or Madam:
    I have to tell you – I love your chicken. It's the best fried chicken around. The breading... I could eat a bucket full of just the breading. Breading and skin. That's the ticket! Anyway, your chicken is outstanding. If I weren't afraid of being arrested, I'd go to KFC to lick other people's fingers – that's how much I like your chicken. Please send me a coupon for a free chicken, so that I do not have to resort to licking strangers' fingers. Thank you in advance,
    Tom Locke, fried chicken enthusiast
