Speaking of things festive, here’s the world’s smallest snowman. At just 0.01 mm across, he’s slimmer than a human hair. Strictly speaking, he’s also made of tin.

The eyes and smile were milled using a focused ion beam, and the nose, which is under 1 µm wide (or 0.001 mm), is ion beam deposited platinum.

The object was built by Dr David Cox of the National Physical Laboratory’s Quantum Detection Group. The video below should give you some idea of just how small the snowman is.

Faithful in sentiment, if not materials or size.

With the season of good cheer fast approaching, I feel it’s time for some of these.

I began my work at a time when invisibility was not fashionable at all.

Physicist Ulf Leonhardt, quoted here, in a piece noting how research into cloaking technologies has become popular and very nearly respectable. Needless to say, there are still one or two problems.

It’s difficult to find anybody in the know who expects there will ever be a device that hides itself and its contents at all wavelengths – if you can’t see it in visible light, then perhaps radar, infrared, ultraviolet or X-rays would reveal it. But optimism for practical uses is growing.

And there’s an issue I don’t recall being acknowledged in Star Trek. 

If a cloak were to make an object fully invisible to the outside world, then the outside world would be invisible to the object within the cloak. A thing (or person) inside a perfect cloak is not only invisible. It is blind.

The video below is by Robert Hodgin, whose digital animations I’ve mentioned briefly here and over at Eye. Hodgin is one of the artists featured in the V&A Museum showcase Decode: Digital Design Sensations. The soundtrack is from WNYC’s Radiolab broadcast Touch at a Distance. A real-time audio responsive version will appear at Decode, which opens on December 8th.
