So this afternoon I was trying to go to the National Association of Science Writers website (that’s an org I’m a member of) and for some reason I went to sciencewriters.org instead (not their website, but wait until you see whose website it IS), and I was rewarded with THE BEST 90’s space/science GIF I’ve ever seen. What does it even mean though? UPDATE (thanks to spaceplasma): Here’s the background on that symbol. It relates to the late biologist Lynn […]

The Engineering Design Show is currently in full swing here, with the competitions for the various design projects. The white-line followers kicked off proceedings. They were pretty impressive, with all but one team successfully being able to follow the (very squiggly) line without mistakes. There were traps to confuse the robots - the line got thinner and thicker, crossed over itself, had abrupt corners and so on, but the robots were well programmed and coped with this easily. The winning […]
