A physicist decries “quantum woo”

You may recall the bizarre “Biocentrism” theory of Dr. Robert Lanza, which I’ve discussed before (here, and here, for instance). I’ve also consulted Official Website Physicist™ Sean Carroll, who pronounced biocentrism pretty much a crock. If you want Lanza’s scholarly explanation of biocentrism (and take a Pepto-Bismol first), read this piece he wrote for The American Scholar (shame […]

Update: Sean Carroll on biocentrism

At my request, Official Website Physicist™ Sean Carroll gave me his take on Robert Lanza’s theory of biocentrism that I discussed this morning. Here’s what Sean emailed me (quoted with permission): Like Chopra, Lanza mixes (1) completely legitimate (but strange sounding) statements about quantum mechanics, (2) tendentious interpretations of what quantum mechanics says that are […]

A physics joke

From reader Ginger K: A Higgs boson walks into a Catholic church.  The priest says, “Hey, you can’t be in here!” To which the Higgs replies, “Why not?  You can’t have mass without me.” Tip your waitress, folks! And don’t forget to try the roast beef.

Steven Weinberg discusses the mysteries of physics

A common misconception is that the major problems of physics have mostly been solved, and all that’s left is some minor sweeping-up.  I doubt that the readers here would agree, for huge surprises and mysteries continue to surface in physics. In a new piece in the New York Review of Books, “Physics: What we do […]

Physics Nobel goes to Englert and Higgs; Sean Carroll kvetches a bit

Well, contrary to Sean Carroll’s guess, the Nobel Prize in Physics was awarded this morning to Peter Higgs and Francois Englert. The news came out only about 20 minutes ago, and is the subject of a terse New York Times piece: STOCKHOLM — Physicists Francois Englert of Belgium and Peter Higgs of Britain have won […]

Debate/discussion: Krauss vs. Craig

UPDATE:  It appears now that the first and third parts of the debate are posted at this link, but I don’t know where part 2 is. They’ve also separated the interviews with Krauss and Craig from the onstage exchange. The Bible Society also has written interviews with Krauss and Craig about the debate.  An excerpt […]

Cat-and-science themed Google doodle

Take a look at today’s Google doodle and guess what it’s about: Of course you guessed correctly when you saw the dead and living cats in the box. Today would have been the 126th birthday of physicist Erwin Schrödinger (1887-1961). As the Guardian notes: However, it was not until his late 30s that he was […]

The physics of a rising chain

Posting will be light this morning as Professor Ceiling Cat has cat stuff to do. In the meantime, entertain yourself with two videos of a remarkable phenomenon of physics: the slinking chain. The first shows the phenomenon, and the second goes into greater detail. A longer video: If you want a more detailed explanation for […]

It’s alive!

But it’s dead in another world! Thanks to several readers for sending this.

Sean Carroll: There is no classical world

I’m not a physicist but wanted to direct you to Preposterous Universe, where, in a new post called “There is no classical world,” Sean Carroll mentions an experiment showing definitively that even a macroscopic object—a mirror cooled to near absolute zero—behaves according to quantum rather than classical mechanics.  That is, instead of remaining absolutely still, […]
