Reminiscing about Fermilab, CAPTCHA tests your physics, science of guitar strings

By Hamish Johnston

What do huge snowstorms, pioneering childcare and bison have in common? The answer is that they all feature in video recollections of Fermilab, the particle physics facility that is celebrating its 50th anniversary this year. A playlist of the videos is available and you can watch Cindy Joe’s musings over Snowpocalypse 2011 above.

According to physics blogger ZapperZ, the online retailer Amazon is developing a new CAPTCHA technology that relies on human’s innate understanding of the laws of physics. The idea, apparently, is that a user would be presented with before and after scenarios and asked which seem plausible. This could be a ball rolling down a ramp, or a projectile flying through the air. It seems that web robots can’t solve simple mechanics problems – at least for now.

Ending on a bright note, music technologist and erstwhile physicist Jonathan Kemp of the University of St Andrew’s in Scotland claims to have invented a revolutionary type of guitar string. He riffs on his new creation in the video above.
