McCain sticking it to the anti-science man

Posted by tigerhawkvok on March 04, 2009 22:47 in politics , news , anti-science

On February 27th, McCain began posting "porkiest projects" on Twitter. He did so again on 3/02, 3/03, and 3/04 (only six on the 4th when I last looked). So these have got to be kinda nutty, right? Or, you know, 13/36 could be science related. How's this for a list?

  1. Apparently museums aren't public goods. Nor the building of produce jobs.
  2. Who needs them there sea turtles anyway. Not like species extirpation has ever caused environmental problems ...
  3. Lobster populations aren't shrinking. Really.
  4. Now, I think nuclear is the way to go, but apparently McCain really has something against solar power
  5. Along the lobster line — no need to keep up those pesky fish populations either.
  6. By the way, we never found out anything useful by studying other species' genetic profiles. Obviously funding that is dumb.
  7. Apparently he is just outright misinformed and doesn't know how problematic — and expensive — theft of copper wires actually is.
  8. By the way. Las Vegas is totally sustainable and uses only its own resources. Not like its a drain on three surrounding states at all.
  9. He really has a bone to pick with population genetics, huh?
  10. To channel Peter Griffin, though, it really grinds my gears when he dismisses astronomy right out.
  11. I suppose McCain never heard how beavers have massive ecosystem impacts, huh?
  12. Startling honey bee decline, anyone? Apparently he just has it out for flowering plants. Who needs angiosperms.
  13. While we're at it, lets just not have as nutrious or plentiful crop for our grazers. Really, genetics is the work of the devil.

Suddenly, I'm gladder I didn't vote for him. I really thought he was more pro-science than that.

The LHC is on, and we're still here

So I was going to make a post about how the world hasn't ended, but you know, this time around, doomsayers can't even doomsay correctly.

That is to say, the Large Hadron Collider, or LHC, turned on today at 10:33 CET, and we're all still here. The test beam went in one direction (not the two necessary you know, for a collision) at less than full power, so doomsayers can't possibly have been correct. However, I think it might be worth listing off a few reasons why the LHC couldn't destroy the Earth:

  • You've got protons. Accelerated really fast. So if you make a black hole, its going to have a really tiny Schwarzschild radius, or the radius of the event horizon (Rs). Like, GMc-2 (to first order). Which is to say, at the speed these guys are traveling, a completely tangential approach would only decay into the black hole at < 1.5Rs. How big is Rs? Ballparking, we have
    (10-11)(10-26)/(1016)=10-43 m. That's really really tiny. And since black holes evaporate roughly as ħm-2, really small things evaporate really really really really fast — in this case, 1020 kg/s. This little mini black hole will need to get within 10-43 m of particles faster than it evaporates, which even at a hairs breadth below the speed of light it doesn't cut it. Really roughly, it'll last:
    10-17m3 s = 10-98 s, Which translates to a distance of under 10-90 m — virtually no distance at all, and an infinitesimal fraction of a nucleus. In fact, being a very small fraction of a Planck length, its virtually meaningless to say it traveled at all.
  • This is a bit more complicated by the fact that black holes have no hair but retain charge, so this will be a charged nearly light-speed traveling black hole. Very small correction, but there.
  • The strangelet hypothesis also won't happen. Sure, colliding strangelets with normal matter can convert normal matter into strange matter. But, cross-sections are again really tiny, and statistics ensures that the reaction would die out by decaying of the strangelet.
