Invisibility physics: “Reflectionless” objects make an appearance
(This is a continuation of my “history of invisibility physics” series of posts. The earlier posts are: Part I, Part II, Part III.) Up through the late 1940s, it seems that the only type of invisibility that authors were considering … Continue reading

Scientific cranks: Going strong since at least 1891
It is easy to assume that scientific crankery is a relatively new phenomenon, perhaps fueled by the completely non-intuitive, sometimes intimidating nature of many modern scientific theories. In physics, for instance, most cranks spend their time attacking Einstein’s theories of … Continue reading

Thomas Levenson’s Newton and the Counterfeiter
About a month ago, I noted that Thomas Levenson’s book Newton and the Counterfeiter (2009) is now available: The book is the story of how the great scientist Isaac Newton, after making the discoveries which electrified the scientific world, took … Continue reading

Maxwell on Faraday
I’m working on a few longer posts at the moment, but in the meantime I thought I’d share a nice little passage I came across while looking through James Clerk Maxwell‘s A Treatise on Electricity and Magnetism (1873). Maxwell, of … Continue reading

Lord Rayleigh vs. the Aether! (1902)
(Note: This is an attempt to get myself rolling on my long-ignored series of posts explaining Einstein’s theories of relativity. It’s also a really cool experiment in the history of science.) One of the most fascinating aspects of 19th century … Continue reading

Invisibility physics: Hiding and seeking, all at once!
When the first papers on the idea of a “cloaking” device came out in 2006, lots of people were immediately worried that the CIA would soon be peering right over their shoulder from the shelter of invisibility cloaks. Many scientists, … Continue reading

Barkla shows that x-rays have polarization (1905)
It is one of the quirks of scientific progress that many great experiments are forgotten as the things they demonstrate become common knowledge in the scientific community. A good example of this is the 1890 experiment of Otto Wiener, which … Continue reading

Invisibility physics: can charged particles self-oscillate?
Time to return to my long-delayed series of posts on the history of invisibility physics! The first two posts were: Acceleration without radiation (1910), describing Ehrenfest’s arguments suggesting acceleration without radiation could be possible, Schott’s radiationless orbits (1933), describing G.A. … Continue reading

Destroying the planet… with science!
When the Large Hadron Collider was fired up for the first time back in September, it caused much wailing and rending of clothes by people who were convinced that the device would create miniature black holes which would destroy the … Continue reading

Who first suggested the nuclear atom?
Here’s a little obscure physics trivia for you: who first suggested that an atom might have a structure consisting of a positively-charged “nucleus” surrounded by orbiting electrons? The easy, and mostly correct, answer is Ernest Rutherford. In 1909, he supervised … Continue reading
