    There is nothing wrong with suggesting that there is differences between genders.

  82. One reason why this is a big deal by MillionthMonkey · · Score: 2

    A neutrino changing its flavor means that the neutrino experiences time. Of course I don't mean "experiences" subjectively, with a consciousness- I mean in the sense that a neutrino can in theory be used as a sort of clock. This effectively rules out the possibility that neutrinos are massless particles.

    In relativity, "proper time" in a moving or stationary frame of reference refers to the time as measured by a clock that is stationary relative to that frame. Your watch always gives you the proper time for your frame of reference- and one of the implicit rules is that proper time always proceeds normally. You will never look down at your watch and see the hands spinning around or standing completely still because that would be silly.
    Massless particles like the photon travel at the speed of light- and in fact a massless particle can ONLY travel at the speed of light. (With exceptions for travel through water, glass, etc.) It makes no sense to talk about the proper time experienced by a photon, because when v=c the denominator in the time dilation equation vanishes. A photon can spend a billion years traveling from a remote galaxy to a telescope here, but from the photon's own "point of view" the travel time was zero. A photon does not experience proper time.

    Now that we've caught neutrinos changing their flavor during their travel, we know that they do experience the passage of proper time, which means they have mass, albeit a very small one. This has some implications for the Standard Model (although I don't know what they are).

    Neutrinos have also been shown to be impervious to humor of all kinds, as has been proven here time and again.

    We need women involved in physics because we want to be able to let women into physics.

    (Huh?)

    There is a huge barrier to women who are interested in physics; there aren't any other women. This may sound stupid to some of you, but think about it: how many women do you know that feel perfectly at home sitting completely outnumbered in a group of geeky males. Sure, a few do, but they are in the minority. Having a stronger female presence (at every level: prof, TA, postdoc, grad student, undergrad, high school teacher, etc) will help to alliveiate this.

    Physics is a rather embarassing case. Other hard sciences have recently allowed their influxes of women: chemistry now has reasonable percentages (if not ideal) and maths are gaining too. Physics remains a holdout.. only a certain type of personality is attracted to physics, and only a fraction of those have the intuition and skills neccessary to make it easy. Take off a fraction for social reasons, and you can get it down to zero.
