Today is Ada Lovelace Day, a celebration of women in tech. Ada was a mathematician and the world’s first programmer; in the mid-19th Century she wrote technical documentation and programs for Charles Babbage’s Analytical Engine.
This year, Suw Charman-Anderson made a pledge: “I will publish a blog post on Tuesday 24th March about a woman in technology whom I admire but only if 1,000 other people will do the same.” Over 1,800 people agreed, and so here you are. Continue reading
The Solar System’s planetary roll call just got longer. From today’s Astronomy Picture of the Day:
One of the strangest objects in the outer Solar System was classified as a dwarf planet last week and given the name Haumea. This designation makes Haumea the fifth designated dwarf planet after Pluto, Ceres, Eris, and Makemake. Haumea’s smooth but oblong shape make it extremely unusual. Along one direction, Haumea is significantly longer than Pluto, while in another direction Haumea has an extent very similar to Pluto, while in the third direction is much smaller. Haumea’s orbit sometimes brings it closer to the Sun than Pluto, but usually Haumea is further away.
It may be just a dwarf planet, but I think it’s interesting enough to visit on the Grand Tour. Who knows what we might find on that (probably) icy planet and its two little moons?

Robert Woodhead, self-described Mad Overlord and all-around geek, has posted an amazing amount of detail from his recent experiment in seeing how the Diet Coke & Mentos reaction works in microgravity. It’s a modification of the now-standard geyser-producing demonstration, but with a twist: performing the trick on a Zero G flight and recording it on a high-speed camera. The Youtube video is great, but the expanded description is even better.
