Cat-turning: the 19th-century scientific cat-dropping craze!
One thing I’ve learn from studying the history of science is that scientists are human beings. Often incredibly weird, weird human beings. For example: in the mid-to-late-1800s, an exciting era in which the foundations of electromagnetic theory were set and … Continue reading

Hiding from time? New design of a “temporal cloak” makes waves
Is it possible to make something invisible in time as well as in space? It is a fascinating question, a provocative question, a mind-boggling question… wait… what exactly does it mean to “make something invisible in time?” We’ll get to … Continue reading

The Kaye effect after dark!
I’ve talked in some detail before about the Kaye effect, in which a shear-thinning fluid such as shampoo or liquid soap can be made to “bounce.” Well, I did one final experiment with the Kaye effect, in order to show … Continue reading

Physics demonstrations: Chladni patterns
A good demonstration of a physical phenomenon should be both insightful and exciting. Sometimes, a demonstration succeeds at both so well that it is practically awe-inspiring. Such is the case, for me, with the demonstration of Chladni patterns, exotic and … Continue reading

Physics demonstrations: cloaking device?
I’ve spent a lot of time on this blog talking about the optics of invisibility, both hypothetical and actual. Though a number of forms of invisibility have been considered in both science and fiction for over a hundred years, the … Continue reading

How to become invisible by “hiding under the carpet”
Since the first theoretical cloaking papers in 2006, the topic of optical invisibility has just gotten stranger and stranger. There have been proposals of optical wormholes, perfect optical illusions, space-time cloaks, and more. Perhaps even more surprising, however, is the … Continue reading

Optical wormholes: punching virtual tunnels in space via metamaterials!
Though the introduction of optical invisibility cloaks in 2006 caused a huge sensation around the world in both the media and the general public, arguably even more significant to the optical science community is the technique used to design cloaks. … Continue reading
