Albert Einstein's very cool leather jacket sold at auction today for £110,500 ($144,424). The coat came complete with the pungent odor of the scientist's pipe. Also on the block were Einstein's pocket watch and toy blocks from his childhood. From Christie's:
‘The jacket first appears in a number of photographs of Einstein, taken at the height of his fame in the mid-1930s,’ (said Christie's specialist Thomas Venning). A shot from 1935 shows the scientist wearing it upon his arrival for a holiday in the Bahamas — ‘improbably paired,’ adds Venning, ‘with a rather natty wing collar’...
Over several years, the jacket aged visibly. ‘Einstein wore it all the time — a fact mentioned in the memoirs of fellow scientist Leopold Infeld, who worked with him at Princeton. Infeld explained that Einstein tried to keep material restrictions to a minimum. Long hair reduced the need for a barber and, he wrote, “one leather jacket solved the coat problem for years.”’

I’ve had quite a few fun afternoons playing with dry ice from making spooky fog in the kitchen to exploding plastic bottles in the yard. But I’ve never had the opportunity to pour hot lava over dry ice. In this video, the lava is 1400 °C and the dry ice is -78C°. So cool! And […]
A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.
