Frontiers in Optics: Monday
The main “act” on Monday at the conference was the Plenary Session/Awards Ceremony. Lots of scientists I’m familiar with (and whom I’ve met at one point or another) were given awards, including Joseph Goodman (known to students for his books … Continue reading

“Liveblogging” What’s Hot in Optics at Frontiers in Optics 2009
Each year, Frontiers in Optics has a session entitled “What’s hot in optics”. I thought I’d “liveblog” it (type it up on my computer and post it later) like I did last year; hopefully the comments make sense, considering I … Continue reading

The first paper on invisibility? (1902)
When discussing the history of invisibility physics, I typically cite Ehrenfest’s 1910 paper on radiationless motions as the first publication dedicated to the subject. Ehrenfest’s paper, which attempts to explain how electrons could oscillate in a classical atom without radiating, … 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

Some musings on negative refraction
For a part of this past week I was at a workshop in California, and a lot of excellent theoretical and experimental researchers of metamaterials were present. One of the points stressed by many of them is the difference between … 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

The National Naval Aviation Museum and a cute optical illusion
Bleah! I’m back from my trip to the Flora-bama area, but didn’t make any jumps — we were essentially weathered out Friday and Saturday, and by Sunday I’d had enough. Most of my jump friends had already bailed, and though … Continue reading

What does negative refraction LOOK like?
My friend Personal Demon recently forwarded me an article that deals with a rather cute idea: Photorealistic ray tracing aids understanding of metamaterials. “Metamaterials” may be described roughly as materials with a man-made structure on the scale of nanometers which … Continue reading
