Meet Elsie MacGill, a legend in aircraft design and production and the first female aircraft designer in the world. In 1938 she became Chief Aeronautical Engineer at Canadian Car and Foundry where she led the production and redesign of several planes including the Hawker Hurricane – the plane responsible for the most British victories in WWII. Most of the employees in the factory were women and by the wars end they had produced 1,400 aircraft, a massive feat. Elsie had forged new […]

11:34 AM | Not Good Enough.
Ed Yong is one of the English language’s better science writers. He often weighs in on issues facing academia, in addition to reporting science. One of the biggest issues facing academia right now is the pipeline problem: too many PhDs are graduating compared with the number of professorships that will ever be available for them. […]

3:45 AM | Big data, prediction, and scientism in the social sciences
Much of my undergrad was spent studying physics, and although I still think that a physics background is great for a theorists in any field, there are some downsides. For example, I used to make jokes like: “soft isn’t the opposite of hard sciences, easy is.” Thankfully, over the years I have started to slowly […]

In the past two weeks, I have been introduced as Mike’s spouse twice in professional settings. I usually view this as something akin to the Kiss of Death: the person receiving this news is likely to consider me an appendage to my spouse and therefore rather useless.  It’s not that I mind people know I […]

1:58 AM | This title isn’t nearly innovative enough
I’ve been pondering a question…and asking a few people, as well. What do you consider innovative? In particular, I’m wondering if people say it is only innovative to have a new idea that no one has thought of before.  What about a different scenario: would you consider it innovative if you came up with a viable […]

6:45 AM | Oh No! Is Math All Wrong?
We all use math in our daily lives. Whether we’re counting objects, adding up money to pay for goods or dividing up food among friends, math is all around us. But what if someone suddenly revealed some proof that 1=2 or that 1=-1 or something like that. Math would be completely ruined! Unless… It’s been […]

Building robots to land on Saturn’s moons Landing an unmanned robot on another planet can be quite a feat and can end up being quite a complex process.  Scientists want to make this process easier but also allow us to explore worlds that are currently too difficult to land on. UC Berkeley professor Alice Agogino is working with doctoral students to build what are known as tensegrity robots.  Essentially, these are robots built with a series of rods and tension wires that protect […]
