  1. Re:Lots of pilots and flight attendants... on TSA Pats Down 3-Year-Old · · Score: 1

    The installed scanners are xray back scatter scanners. The give very high resolution images compared to mm wave and unlike medical xray equipment (with trained personnel), you get some TSA goon being responsible for your xray calibration and dosage.

    Not a single photon even after 100s of times the age of the universe is not a "tiny fraction" by any stretch of the imagination. Its none.

    The *size* of a photon in the visible region is much larger than an atom. Blue light is in the 400nm range while an atoms radius is in the 0.1nm range. So a photon intersects many atoms.. often all at once.

    For many materials nothing ever effectively sneaks through at least in the visible region.

    Physicists don't actually use terms like "opaque" very often.

    Yes we do.

    Tunneling is exponential in nature. If you get say 1 in 10 photons through a 1um think piece of material. Then you only get a 1 in 100 with 2um thick.

    Now lets assume that the thickness is now 1mm. Now just one photon in 1x10^1000 gets through.

    Now lets assume we have a red laser (700nm) that has a power output of the sun (3.846×10^26 W). Thats 1.3x10^45 photons per second. After waiting 1000 billion years, thats still only 4.5x10^55 photons. So none get through. You could use all the energy in the visible universe and still not a single photon gets through.

    So in other words, there really is such a thing as truly opaque objects.

    By the way. Much less than one in ten photons of 700nm light would get through most pure metals.

  10. Re:Visible? Opaque? on Visible Light 'X-Ray' Sees Through Solid Objects · · Score: 1

    Not really. 1mm of just about any pure metal will not transmit any visible wavelengths till the light source is powerful enough to vaporize it.

    I was referring to musicians in particular, since thats the topic. What i am taking about is that if a bar/pub organized *independent* artist to be played on the stereo with permission of these artists. They still are forced to pay the organization that collects money for public performances etc even though they *don't* represent or pay these artists

    This is depressingly insightful. It has never been about the artists. Or they would be permitted to be independent.

    I always thought the GPL reading of derived work sounding more like something that the MPAA come up with. If i reference another text book, and the information in the other textbook is needed to understand my book. Its still not a derivative work as far as any reasonable person would claim. Yet that's what the GPL claims is (as far as I understand).

    I have always liked Linus much more pragmatic approach to the whole thing.

  16. Re:Perspective on Kepler Spacecraft Finds System With Multiple Planets Transiting the Star · · Score: 1

    It has always been assumed that they had planets, or that its at least common on stars with the right composition and no close binary partner. But since we had only one set of observations, ie here. A lot of protoplantary disk dynamics was blind guess work. Now its just guess work.

    We have already learnt some interesting things. The number of large Jupiter size planets that are in close orbits is much higher than expected. So migration after formation seems to be more important that first suspected (Uranus IIRC migrated quite a bit)

    Well perfect fusion engines can get you say 1-10%c. That's doable for space probes. Antimatter is also theoretically possible. The efficiency bound for antiproton production is at least 1%, then 50%c and higher becomes something we can talk about. Then there are beamed energy proposals.
