01:54 < streety> "9800 newtons of force to press a pin into a dowel" & "Boeing 737 engine produces 64 kilonewtons of thrust" - At least one of these seems wrong. I think the engine would be able to push more than 7 pins into dowels simultaneously. I suspect I would be able to manage at least one, perhaps two, and I weigh far less than a tonne.
02:08 < fenn> the first figure is wrong, if you're thinking of some sort of sewing machine pin. but it's probably referring to inserting a precision steel machine part into another machine part with a tight interference fit
02:08 < fenn> the kind of thing you do at an arbor press or hydraulic press frame
02:09 < fenn> and 45 mN is plenty for a satellite thruster
02:10 < fenn> i just don't believe it, and the inventor creeps me out, and i wonder why we're talking about yet another propulsion investment scam / crank / exercise in critical thinking

06:32 < kanzure> "In the mammalian cortex, analog error correction codes known as grid codes have been observed to protect states against neural spiking noise, but their role in information processing is unclear. Here, we use these biological codes to show that a universal fault-tolerant neural network can be achieved if the faultiness of each neuron lies below a sharp threshold, which we find coincides in ...

17:45 < lsneff> What's a cool project I could do with an FPGA? I have one in mind that involves building a levitating magnetic stage, but I don't have the time to do that right noww.
