Yesterday was the 110th anniversary of air conditioning. The building pictured above—1040 Metropolitan Ave. in the Williamsburg neighborhood of Brooklyn, New York—was the first building in the world to enjoy the luxury of cold air blowing on a blisteringly hot day.
A junior engineer from a furnace company figured out a solution so simple that it had eluded everyone from Leonardo da Vinci to the naval engineers ordered to cool the White House when President James A. Garfield was dying: controlling humidity.
The junior engineer who tackled the problem was Willis Carrier, who went on to start Carrier Corporation. The solution he devised involved fans, ducts, heaters and perforated pipes ... Carrier’s plan was to force air across pipes filled with cool water from a well between the two buildings, but in 1903, he added a refrigerating machine to cool the pipes faster.
It's a neat technological story, and as the New York Times piece points out, Carrier's invention wasn't just about making people comfortable. In the beginning, it was about allowing a specific job to get done even when the weather was hot. In fact, air conditioning is still the tool that makes things like computers possible, by creating dust-free, low-humidity clean rooms where the parts can be manufactured.

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.
