Comment Re:Bigger star = faster orbit (Score 2) 40

I should probably check that before I post to slashdot, because they'll be cruel if I remember incorrectly. But, eh. I'll take my chances.

You lose! For exoplanets of mass insignificant compared to its parent star, the relation is
M(star) x Period^2 = Distance^3

So if the mass of the star were doubled, the period would decrease by a factor of 0.7071. And if the orbital radius doubled, the period would increase by a factor of 2.828.

On the plus side, that would alleviate the global warming situation, although to a degree of compensation much to our detriment.

tell him the paint is wet and he'll touch it to find out....

He should believe you on faith alone?

No, but if the guy telling you that the paint is wet is
standing there with a brush and bucket of the same color, and fresh splatters on his overalls;
and you heard some fat drug addict on the radio said that "Hitler was a painter! They want your light bulbs!";
and fuck, you never painted anything yourself but what does this brush-toting shit know about it;
and sure, you saw him touching the brush to the bench as you were walking up, but you just *feel* that no one has enough data to know about the bench since *you* don't;
plus, on Sunday your preacher said that only SkyDaddy Longbeard can paint a bench;
and THEN you touch the paint to see if it's wet, then YOU ARE A FUCKING IDIOT. And an asshole to boot.

Signed, a Painter (but not of benches), who has received enough crackpot letters from armchair fuckfaces and religious shitheads to know the goddam score.

Oh my FSM don't send him straight to the Black Death. MTW is good once you know the ground, but opening it prematurely is the leading cause of spontaneous human combustion.

Take calculus. Once you're good at it take vector calculus. Once you're good at THAT chase down a book by Ivan Sokolnikoff called Tensor Analysis: Theory and Applications to Geometry and Mechanics of Continua. It's out of print, last I checked, but it's in most university libraries; iirc the call number it's QA 433 .S64 (that book spent a LOT of time on my desk in grad school).

After that, read up on some differential geometry and wade into MTW. Good luck.

I had an eye-opening experience back when i bought my one apple product, an ipod nano (7 years or so ago), the 8GB model. I had it loaded up with music, and after reinstalling, wanted to get my music back by syncing it with the newly installed itunes. The result was a wiped ipod, as apple does not want me to own my data. Lession leaned.

PEBCAK.
1) Wipe iPod and enable for disk use.
2) Back up music library before reinstalling OS.
3) Drag music files back into iTunes.
4) Go on with life.

Unless you meant that the lesson learned was to back your shit up before reinstalling, you learned the wrong lesson.

I would suggest to you that if you believe in AGW, and cannot identify those concise statements, you are operating in terms of a religion, not science.

Firstly, the physics behind the greenhouse gas hypothesis in general and CO2 in particular has been known for over a hundred years (thank you, Arrhenius). The global impact of an atmosphere with significant opacity to the spectrum of a planet's expected blackbody temperature given its distance from the Sun is easily observed for the Earth-similar planet Venus, which at 735 K exceeds the expected value of 465 K. Similar calculations for the Earth show the atmosphere raises its temperature by about 20 K; Mars can be done as a sanity check. CO2's power as a greenhouse gas on Earth is further compounded by its persistence in its gas state at terrestrial temperature and pressure, as distinct from water vapor. Because of its spectral properties methane is also an effective greenhouse gas, but its lifetime in the atmosphere is considerably shorter. Ergo, the one to watch in the case of the Earth is CO2. So let's hold as established the mechanism of global warming. How do we know it is anthropogenic? One argument is that fossil fuels should have a different isotopic ratios in their carbon content, which should be reflected in the CO2 if the contribution of its burning is significant. This has been shown. Additionally, as the CO2 fraction in the air increases under this AGW hypothesis, it should also increase in the oceans, resulting in noticeable acidification in the short term. This too has been shown (most obviously to laymen in the observed bleaching of coral reefs). One would hope that the consequences of taking carbon sequestered from the atmosphere at a much earlier (and, needless to say, warmer) time in the Earth's history and releasing it at a rate that far exceeds the rate at which it can be re-removed (and, in fact, lowering that rate in the oceans through the resulting temperature increase) would be obvious. That hope can only survive in those who do not interact with actual people and their daily displays of willful blindness and rampant stupidity. Regardless the Universe doesn't give a shit, so I have given you a few of the AGW arguments, expressed in the broad-brush manner the format allows. Notice that I did all of this without relying rhetorically on my Ph.D. in astrophysics, since that might be construed as an appeal to authority. So as you can see, I am quite familiar with them, so you can take your attempt at condescension through your suggestion, fold it five ways, and shove it up your arse. Watch your head, though.

-- Relying on the Pope for information on the tenets of the Catholic Church = proper appeal to authority.
-- Relying on the Pope for sex tips to drive the ladies wild = fallacious appeal to authority.

Also, just because you don't know the concise statements of a falsifiable hypothesis for AGW doesn't mean they don't exist. Might I suggest you make a proper appeal to authority/ (Hint: they don't have AM talk radio shows)

Ending all wars ? Yeah right. Are you really moronic enough to think the middle east will stop fighting without oil ?

My feeling is, that if you are going to call a poster moronic, you should be a careful enough reader to notice that he wrote "oil wars", not "all wars". Unless you are an organism that feasts upon one's own irony.
