There's this "Sun" bombarding the planet with energy, constantly.
Then take the two-body system given by the Earth and the Sun as the closed system.
If it was a closed system the Earth would have cooked by now coming to equilibrium with the Sun - fortunately we have the cold bath of the rest of the universe to which most of the Sun's energy flows, as well as some heat from the night side of the Earth - so it is not a closed system.
Do you really think that an IRL Sheldon without script immunity would be able to do the same? The TV Sheldon also seems to be a pretty crap physicist, given to conspiracy theories, junk science, and an inability to distinguish between fiction and reality.
I was an undergrad Physics major at Caltech. Other than the crap physicist qualifier, I knew professors in the department who were given to conspiracy theories, junk science, and an inability to distinguish between fiction and reality, though not all in a single individual.
One could argue that in most cases, a pedestrian paying attention could have avoided getting ran over if they'd pulled their heads out of their phones long enough to look around them.
SFPD claims to be keeping better stats these days but I could not find them online.
However here is what I did find: http://www.ktvu.com/news/news/...
All three victims this year entered the crosswalk only after pushing a button to activate several flashing beacons to alert drivers to stop. There are six lanes of traffic across Sunset with an island in the middle. Thursday's crash occurred when several drivers stopped, but a Honda CRV kept going. The driver noticed the woman too late and skidded into her, clipping her with the front bumper and spinning her to the pavement. "She said she didn't see her, " San Franicsco Police Officer Gian Tozzini told KTVU. "I don't know how she didn't see the flashers. Maybe they're just looking forward and not paying attention."
That is three victims, one fatally injured, at a single crosswalk with flashing lights in the Sunset. The description matches what I see in my little New England town where I'll slow because I see a deer stepping into the road and the car behind me thinks they need to pass me on a two lane road so as not to slow down at all - not sure how bad I'd feel other than for the deer. A pedestrian was hit in our crosswalk same way - one car stopped, person started walking, car behind did not even slow down and passed in the next lane hitting the person in the crosswalk - actually tossing them into the front window of another car that had also stopped on the other side for the pedestrian - that car was full of kids coming home from little league.
So running a conductor through a changing magnetic field will no longer produce a charge?
No it won't. It will produce an electric field which can be used to push charges around, but will not produce a charge.
Putting two lead oxide plates in an acid batch will no longer cause a chemical reaction?
Nope - no electrochemical reaction. You need metals of differing electronegativity, like Pb and PbO2.
My goodness, I was unaware that a catastrophe large enough to cause an apocalyptic event would change the fundamental laws of physics.
You're right it won't, but you might want to brush up on what they are before the apocalypse.
You sound young.
There is no way to build a game on Android that can run at the speed the benchmarks are getting run at on each of the devices "cheating".
What happens if you name your game to match the benchmark that the phone is looking for?
I loved using this in the mid 90s. I was 5x to 10x productive. But there was no diff available, no way to do SCM, it was hard to come back to code I'd written 6 months before and refresh my memory of what it did. And it was next to impossible to collaborate will a team. I was forced to use http://en.wikipedia.org/wiki/Executable_UML using some horrible tools (Kennedy Carter iUML) in the 2005s - same exact problems.
Now iBuilder or what ever the I tool is in XCode is pretty nice. But building software that works, is maintainable, is extendible, and so on is a hard task - I don't think it is the lack of drag and drop tools.
