  1. Re:iirc on Wolfram Alpha Rekindles Campus Math Tool Debate · · Score: 1

    Oh and we were not allowed to use calculators (this is the top university in the state).

    You mean this isn't common? I know nothing else. I seldom had exams where (non-graphing, non-programmable) calculators were allowed, but they were of no use then, anyway. I carry around a calculator like this, but only for crunching numbers.

    Well, and I don't know where the details in TFA here posted came from. Actually, the german article states some facts differently (I'll try a translation, umlauts were replaced by me, because /. sucks at Unicode):

    "Erst habe ich nur einen grossen, weissen Lichtkegel gesehen. Meine Hand hat weh getan, dann hat es geknallt."

    "First I saw only a big, white cone of light. My hand hurt, then there was a bang."

    "Nachdem ich das weisse Licht gesehen habe, habe ich an meiner Hand etwas gespuert. Ich denke, dass mich der Meteorit gestreift hat. Vielleicht war es aber auch nur die Hitze", berichtet er und zeigt den Ruecken seiner linken Hand. Die rund zehn Zentimeter lange Brandwunde ueberdeckt bereits eine Kruste. "Das Geraeusch, das folgte, klang wie das Reissen einer Steinplatte und war ziemlich laut", erinnert sich Gerrit und deutet auf den kleinen Kreis aufgeplatzten Asphalts zu seinen Fuessen.

    "After I saw the white light, I felt something at my hand. I think, the meteorite streaked me. But maybe it was only the heat." he reported and shows the back of his left hand. A brand around 10 centimeters long is already covered by an eschar. "The sound that followed, sounded like a paver being ripped apart and it was pretty loud", he comemorates and points to a small circle of burst open bitumen by his feet.

    There's also a picture where one can see the "crater" in front: http://www.derwesten.de/nachrichten/staedte/essen/2009/6/10/news-122286237/imageshow.html?resourceId=picture23923142 (the caption reads: "Gerrit Blank shows his brand and the meteorite that streaked him, while it was falling, near the "crater".

    The Drake equation is exact, but we have no idea how large a few of the factors are, so the true probability is anyone's guess, really.

    How can it be exact, then? Do you really think that mathematical models of physical reality can be exact?

    Calculus. Leibniz and Newton are not co-inventors - not really anyway. Basically they both built on work done by others including al-Haythem and other decidedly non-German mathematicians. The difference is that Newton did something truly amazing (and innovative) with it.

    Lebnitz's notation is in widespread use today. And what about the binary system?

    Quantum physics. As you say 'developed part of the foundation.' Quantum theory developed gradually, with contributions of a lot of people from a lot of places.

    Planck started it.

    Einstein was from Austria by the way.

    Wrong.

    I have a few more:

    • David Hilbert
    • Werner Heisenberg (uncertainty principle)
    • Fritz Haber (Haber-Bosch process)
    • Walter Hermann Nernst (third law of thermodynamics)
    • Otto Hahn and Fritz Strassmann (discovery of nuclear fission)
    • Robert Koch
    • Wolfgang Paul (paul trap)
  6. Re:The great Lem on The Futurological Congress · · Score: 1

    I read the book first (which is IMHO the best novel from Lem i read so far) and only watched the film with Clooney. And this film just sucks. The whole main theme of the book - a philosophical take on human cognition - was left out completely. But maybe I'm a bit special. I think Abrams version of Star Trek sucks, too, because everything Star Trek stood for was thrown away by Abrams and replaced by action sequences composed of shiny CGIs.

    AFAIK "to offend" means "to annoy" and "to insult". So this is just a bad translation. Criticism isn't forbidden, but insults and hate speech are.

    There's an incongruity between what i said and what i meant, so it's irony. For xenophobia: i thought that this girl was abducted, but wikipedia states that this isn't clear. So your remark about "unfamiliar environment" (as another post mentions) may be valid. My bad.

    During 1 femtosecond. Power = Energy/Time. I don't know how much power the entire grid of north america puts out, but to give an example: 1 joule of energy delivered in 1 femtosecond would be equal to about 1 peta watts of power. Actually a LASER-pulse wouldn't be of the form of a box function but more a gaussian or sth. similar. So the peak power would be higher than this averaged output.

    BTW, femtosecond LASERs have been around for quite some time. Attosecond LASERs have already been made.

    I coded both with Vim and IDEs like Eclipse or KDevelop, but I never found the GNU equivalents for graphical UML modelling and class/objects trees. Or easy ways to integrate gdb with vim like so many IDEs integrate their debugger. When working with gdb I always have to search the right line in the backtrace and then jump to the line in the source code manually. That's a typical repetetive task that gets strenous after a while. Or when editing LaTeX: IDEs like Kile have a list for inserting special symbols for math mode; with vim I always start to search my little LaTeX book or the web because I can't (and won't) remember all special symbols that there are.
