  1. Re:Why? on Messenger's Mercury Trip Ends With a Bang, and Silence · · Score: 0

    due to that damned effect I forgot the name of and can't find an Google.

    Kozai mechanism?

  2. Re:what about my car... on Heat Engines Shrunk By Seven Orders of Magnitude · · Score: 0

    The vast majority of motors that power our planes, trains, and automobiles are heat engines...Today, the smallest heat engines have a volume of some 10^7 cubic micrometers.

    If engine of your car is much bigger than that, you should consider replacing your car.

    Though if they let fly anyone but jews, they're probably in trouble.

  5. Re:ridiculous references on Ants Vs. Worms — Computer Security Mimics Nature · · Score: 0

    "When a digital ant detects a threat, it doesn't take long for an army of ants to converge at that location, drawing the attention of human operators who step in to investigate". You see, they are like real ants - a single "digital ant" is unable to do anything about the threat. Also, humans are incapable of noticing the "scent" that single "digital ant" leaves. No, one has to wait for a lots of other ants to come. This takes time. ..I'm not so sure nothing is traveling inside _their_ cables. There must be a reason they need an army of ants.

  6. Re:Reducing emissions does nothing on UK Royal Society Claims Geo-Engineering Feasible · · Score: 0

    No, let's better chop the forrests and plant corn for ecological fuel. Just don't mention trees remove more CO2 from atmosphere than corn and (mostly) everyone will be happy.

  7. Re:n/a on Fatty Foods Affect Memory and Exercise Performance · · Score: 1

    From the fta: "the researchers have also performed similar studies of high-fat diets in healthy young men"

  8. n/a on Fatty Foods Affect Memory and Exercise Performance · · Score: 1, Interesting

    Were all participants americans? If yes, this study says nothing about the rest of world population. Seriously, metabolism of humans differs across the world, like for example asians can't metabolize alcohol well.

  9. Re:nothing special... on People Emit Visible Light · · Score: 1

    Well, people do emit some visibe light because of their temperature, but this does now explain why face is way brighter or why the brightness varies with time. Of course, the temperature is not constant, but I believe the differences are too small to account this.

  10. Re:What I want to know is... on MIT Electric Car May Outperform Rival Gas Models · · Score: 1

    Two batteries can be charged in the same amount of time as one, yet they have twice as much capacity. They have almost 8K cells.

  11. Re:Math ftl on Visualizing False Positives In Broad Screening · · Score: 1

    ROC is useful not only to choose optimal threshold, but to see how good the test is, too. They have a reason not to show it. "90% accuracy" probably seems pretty good for average person, but when everyone one that for more reasonable false acceptance rate like 1E-5 false acceptance rate is 1E-4 (wild guess), it is clearly useless.

    I asked the mathematician what is the probabilty of bomb being on the plane. He told me one in a thousand. I asked what is the probability of two bombs. He told one in a million. So I always carry a bomb with myself when I travel by plane.
