Feser to Krauss: Shut up because of the Uncaused Cause

I didn’t know anything about the Witherspoon institute, where Catholic religious philosopher Edward Feser has published a strident piece called “Scientists should tell Lawrence Krauss to shut up already“, but it appears to be a right-wing think tank. According to Wikipedia: The Witherspoon Institute opposes abortion and same-sex marriage and deals with embryonic stem cell research, […]

Schrödinger’s bacterium: physicists plan to put a microbe in two places at the same time

Okay, this is WAY above my pay grade, but I’ve been sent articles on this by several authors, including an explanation at the Guardian. It’s a description by two theoretical physicists of an experiment that uses quantum superposition to put a bacterium in two places at the same time. They plan to collaborate with experimentalists to actually carry it […]

Stephen Hawking to give the 2015 Reith Lectures

Professor Ceiling Cat is going home to rest, but before I do I want to call your attention, courtesy of reader Dermot C., to the fact that Stephen Hawking will be giving this year’s series of Reith Lectures for the BBC. This prestigious series has featured leading thinkers since 1948, when Bertrand Russell first spoke on “Authority and […]

Steven Weinberg’s new book on the history of science (with excerpts)

It’s a great pity that Steven Weinberg’s new book on the history of science, To Explain the World: The Discovery of Modern Science, is coming out too late to be included in my own book, in which I discuss the apologists’ contention that science was an outgrowth of medieval Christianity. Weinberg’s book, whose existence I discovered through a […]

Lawrence Krauss rebuts “Science increasingly makes the case for God”

On Christmas Day of last year, the Wall Street Journal published a short piece by Eric Metaxas called “Science increasingly makes the case for God” (The subtitle is “The odds of life existing on another planet grow ever longer. Intelligent design, anyone?”). If the WSJ link takes you to the subscription page, just Google the […]

Why the Sun doesn’t go around the Earth

Earlier I asked readers to think about (and comment on) why, if motion is relative, it still makes more sense to say that the Earth orbits the Sun than vice versa.  I had my own take, but the answer is not super-obvious. So I asked Official Website Physicist™ Sean Carroll for the answer, and here’s […]

Grape plasma

Who would have thought that you could microwave a cut grape for just a few seconds, and produce a glowing plasma in your microwave. Have a look at this instructional video (NOTE: I am not telling you to try this at home, but if you do, report back.) The explanation, from Now I Know: The […]

Nobel Prize for Physics goes to three who invented a light-emitting diode

This happened about 45 minutes ago, and here’s my CNN bulletin This year’s Nobel Prize for physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources,” the awarding committee said. The committee said the trio’s work […]

Zero-G kittehs

I always thought Russians were the world’s greatest cat lovers—until I saw this video. Reader Stephen Q. Muth, better known as Butter’s Staff, sends this intriguing video of a cat (and two mice, barely visible) subjected to zero gravity on one of those airplane rides where, as a plane goes over the top of a parabolic arc, […]

Another Schrödinger’s cat meme

It’s the end of a very long week. I’ll be leaving tomorrow afternoon, so there will be a Caturday felid, a Hili dialogue, and perhaps a few sundry treats before I take off for the Chicago-Warsaw leg. In the meantime, have a cat: From Super-Fun-Pak Comix by Ruben Bolling: Or, in Hili’s case, napping and lapping […]
