Submission + - New Technique to Develop Single Molecule Diode

William Robinson writes: Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a single-molecule diode, that has rectification ratio as high as 250, and 'ON' current as high as 0.1 microamps. The idea of creating a single-molecule diode was suggested by Arieh Aviram and Mark Ratner who theorized in 1974, which has been the 'holy grail' of molecular electronics ever since its inception to achieve further miniaturization, because single molecule represent the limit of miniaturization.

Dude If that thing spawns an "Earth eating black hole" living next door to it would be like about Mars. What everybody forgets is a blackhole has conservation of mass, charge and angular momentum, so a blackhole whizzing around the LHC ring would act pretty much like every other thingy whizzing around with the same mass, charge and angular momentum. Even if the blackhole escaped the ring, it would only be a blackhole as long as it's energy was high enough to maintain it's event horizon; that energy is dependant on it's velocity, which is a vector involving speed and direction! Yeah that's right a quantum blackhole can un-blacken if it collides with another particle and loses energy, it can un-blacken through Hawking radiation and it's only black if your close enough to it's direction of travel.

If you layer a guitar with enough delay, chorus, compression, tube distortion, tape saturation, EQ, and maybe some octave effects, even a rudimentary player is going to sound pretty killer.

Rubbish. I can strum about three chords from memory and six if I study them before playing.

The only way you could make me sound like Clapton, Page or Blackmore would be to erase all my shit and record them over the top.

Comment Re:Which string theory? (Score 0) 148

Imagine a "theory" with a bunch of adjustments. So many adjustmentrs that no matter what happens, there is some adjustment that canm be made such that it "retroactively) predicts it. That is string theory.

The big problem with string "theory" is that it predicts everything and so, nothing.

String toolkit might be a better name. It is just that, a bag of parts and tools that might one day be used to construct a theory that predicts something in particular.

So your saying that Climatology is a sub-discipline of String Theory?

Close but the Schwartzschild radius solution only applies to non-rotating bodies and any particle I can think of that is subject to relativistic mass increases also have spin, a closer fit would be a Kerr–Newman metric, however I'd assume that these solutions ignore external gravitational fields, which might be valid approximation over interstellar distances, it might not be valid in Earth's atmosphere for cosmic rays or inside the LHC. Perhaps a real physicist could chime in with a more learned point of view.

Submission + - You destroy basic usability by hijacking the scrollbar

Presto Vivace writes: Facebook vs the news media

Here’s an absolute fact that all of these reporters, columnists, and media pundits need to get into their heads:
The web doesn’t suck. Your websites suck.
All of your websites suck.
You destroy basic usability by hijacking the scrollbar. You take native functionality (scrolling, selection, links, loading) that is fast and efficient and you rewrite it with ‘cutting edge’ javascript toolkits and frameworks so that it is slow and buggy and broken. You balloon your websites with megabytes of cruft. You ignore best practices. You take something that works and is complementary to your business and turn it into a liability.
The lousy performance of your websites becomes a defensive moat around Facebook.
Of course, Facebook might still win even if you all had awesome websites, but you can’t even begin to compete with it until you fix the foundation of your business.

Comment More than two sides (Re:more govenrnment waste!!) (Score -1) 389

Those people who view one side as better than the other, because they are "less evil" are simply delusional.

There are more than two sides. Rand Paul — currently from the "Libertarian wing" of the Republican Party — may as well become a bona-fide Libertarian. At least, that would assure a Presidential nomination for him.

Whatever he does, his attempts to block the extensions of this "most unpatriotic law" gained him support from both sides of the traditional isle (as his other actions did before).

Libertarianism has been rising over the last few decades — one can see it from Slashdot's own poll as well as feel it in the increasingly shrill reaction Libertarian ideas get from Slashdot's resident Statists. Maybe, we'll have three major parties once again soon.
