You say "Observational evidence", I say "Our models are wrong".
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
For my next exam, if I get x==3 as a result and I know it should be x==100, I'll just define dark_x = 97.
Yeah, GP doesn't really get the second law of thermodynamics.
You cannot masturbate while driving a diesel car in France?
Or you know, people could accept reality and the fact that it might not be a good idea to have very thirsty trees at all in California.
What's your next argument? "We invested a lot in this golf course and giant pools in Las Vegas, so let's forget we're in the friggin desert".
Also, you have to make significant efforts to lower your water usage to 200l per person per day? Gee, I wonder why you got an 8 year drought.
Doing what is best for you doesn't always imply to screw your allies.
Talking about it, there's a very interesting movie about Shin Beth/Israel/Israeli government :
The Gatekeepers http://www.imdb.com/title/tt23...
You realize it's not just a USB port, but the laptop charger and video cable ports as well?
So your car can carry at most one luggage, but only if you're not at the gas station and if your passengers aren't using the backseat dvd player.
Right now, a lot of us sit in front of a desk, while oil does most of the job for us(see http://en.wikipedia.org/wiki/E...).
It might change in one or 2 decades.
I'm in that camp too. But :
I tried to put an incandescent light bulb close to my screen, took 3 steps back and squinted a little.
The dress still doesn't look clearly blue/black to me, but the blueish tone is now much more saturated and dark, and the gold is dark enough that it could be black with some orange highlights.
The effect is gone when I walk back to the screen, but at least I can understand that it can look blue/black to some people (=morons).
Thank you. GP is just a guy with a camera who thinks he understands it all just because he was lucky to process the dress as black and blue.
I've also seen enough pixels in my youth to think that I got it right : unfortunately, there's just not enough context, and I cannot see any other color than white and gold.
I'm not sure about the 2 first questions.
http://www.sr.bham.ac.uk/~tjp/... seems to suggest that apparent magnitude is based on flux (=total amount of light), and not on intensity (=light density).
It means that the light density of Betelgeuse supernova would be much higher than the light density of the quarter moon. The total amount would be approximately the same. If I'm not mistaken, since the sun (32.7 arcminutes) is much bigger than Betelgeuse (0.056 arcseconds), Betelgeuse supernova would also have a much higer intensity than the Sun.
A bit more than "a little brighter".
It would go from 0.5 (now) to -10 apparent magnitude. That's about 15000 times brighter.
It would be much brighter than Venus/Jupiter/Sirius, and be visible during daytime.
It would be about as bright as a quarter moon.
When was alcohol considered really good for your health?
When was marijuana considered really bad for your health?
The worst side effects for marijuana have always been those linked to prohibition :
* landing in jail
* supporting mafia
As far as marijuana being possibly linked to mental illness, I think it's more of a correlation than causation.
The same goes for those studies about heavy marijuana use at a young age. If you can smoke pot all day long at 14, I think you're life isn't screwed solely because of weed.
