This Saturday I’m getting married! The following week I’ll be in Barbados relaxing on my honeymoon. While Barbados is a highly developed Caribbean economy with no shortage of internet access, in the interests of relaxation and matrimonial bliss I shall not be online. Posting will resume the following week.
Until then, I’ll leave you with this Wired article about a wind-powered car that travels directly downwind faster than the wind. When I first read the idea, I thought “No, that’s an obvious violation of the laws of nature and everyone involved is an idiot.” Well, the proof is in the pudding and if you don’t find the physics explanation particularly intuitive (I still don’t really intuitively grok it, though I get the idea), the fact that they actually built and drove the thing at about 3x wind speed settles the argument.
Perpetual motion guys take note – on the off chance we’re wrong about conservation of energy the way to get our attention is not with long-winded emails about some grand conspiracy, it’s to build the thing and park it outside a physics building. After it keeps running for a few weeks I bet people will pay attention. But personally I’d strongly advise you that there’s better uses of your time.
Anyway, see y’all around!
