Happy Ada Lovelace Day!

Today is Ada Lovelace Day, a day to celebrate and encourage women in the fields of science and technology. The day is named after Augusta Ada King-Noel, Countess of Lovelace, born Byron. (You can see why we just call her Ada Lovelace.) She was a brilliant mathematician, and the writer of what’s probably the first real computer program — it computed the Bernoulli series. At least according Charles Babbage, in correspondence to Michael Faraday, she was an “enchanted math fairy”. Not only a proto-coder, she wrote almost all of the existing documentation about Babbage’s computation engine. She’s a stellar example …read more

Using A Thermal Camera To Spot A Broken Wrist

Chemist and Biochemist [Thunderf00t] has shown us a really interesting video in which you can spot the wrist he broke 10 years ago using a thermal camera.

He was on an exercise bike while filming himself on a high-resolution thermal camera, As his body started to heat up he noticed that one hand was not dumping as much heat as the other. In fact one was dumping very little heat. Being a man of science he knew there must be some explanation for this. He eventually came to the conclusion that during a nasty wrist breaking incident about 10 years …read more

Gain Access to Science Two Ways

Not a hack, but something we’ve been wanting to see forever is open access to all scientific publications. If we can soapbox for a few seconds, it’s a crying shame that most academic science research is funded by public money, and then we’re required to pay for it again in the form of journal subscriptions or online payments if we want to read it. We don’t like science being hidden behind a paywall, and neither do the scientists whose work is hidden from wider view.

Here are two heartening developments: Unpaywall is a browser extension that automates the search for …read more

PUFFER: A Smartphone-Sized Planetary Explorer

Is there room on Mars and Europa for cute robots? [NASA] — collaborating with [UC Berkley] and [Distant Focus Corporation] — have the answer: PUFFER, a robot inspired by origami.

PUFFER — which stands for Pop-Up Flat-Folding Explorer Robot — is able to sense objects and adjust its profile accordingly by ‘folding’ itself into a smaller size to fit itself into nooks and crannies. It was designed so multiple PUFFERs could reside inside a larger craft and then be deployed to scout otherwise inaccessible terrain. Caves, lava tubes and shaded rock overhangs that could shelter organic material are prime candidates …read more

Hacked Diamond Makes Two-Atom Radio

It used to be pretty keen to stuff a radio receiver into an Altoid’s tin, or to whip up a tiny crystal receiver from a razor blade and a pencil stub. But Harvard researchers have far surpassed those achievements in miniaturization with a nano-scale FM receiver built from a hacked diamond.

As with all such research, the experiments in [Marko Lončar]’s lab are nowhere near as simple as the press release makes things sound. While it’s true that a two-atom cell is the minimal BOM for a detector, the device heard belting out a seasonal favorite from [Andy Williams] in …read more
