Comment The folding@home guys need to watch more House MD (Score 1) 88

In House MD when they suggest a diagnosis that means sure death for the patient that diagnosis is ignored because if it has no practical use anyway, no matter if it is true or not. The same logic should be applied to the folding@home project. If these guys are correct and we need to brute force this problem the way they're doing it, we're basically screwed because even with moores law running for decades more we'll still not be able to computationally solve novel proteins in any meaningful time. In essence, if they are correct we should shut down folding@home directly and focus all our efforts on high throughput electron/xray/nmr/syncrotron crystallographic methods because they have at least a theoretical chance of being practically useful. One wonders why people like this manage to secure funding for such a large scale death march.

Comment Read the book! (Score 1) 436

Orwell explains why you become invisible in the intervening time when time travelling in the book "The Time Machine", which the movie is based upon.

Basically it goes like this: the amount of interaction between a time traveller T and an object O is directly proportional to the speed difference. If T moves at 200 times the normal speed of time (taking him forward 200 seconds for each second O experiences as moving forward) the electromagnetic forces will have 1/200:th of the chance to interact, and thus will interact 1/200:th as much. This also explains why T can see the outside world, because although each second gets 1/200:th of a photon per photon, he also gets 200 times the photons, which ends up as 1/1, so light will be as bright to him as if he was travelling at normal speed.
