It would be very nice if we could launch rockets horizontally because they would be accelerating in the needed direction to attain orbit velocity. Unfortunately air drag is so high at supersonic speeds so rockets are launched vertically up until they get out of the densest part of the atmosphere and then a gravity turn (uncontrolled) is made to point the rocket to the east. You are right it would take the same amount of energy if gravity was the only acting force, since it is a conservative force. But drag force isn't.
XML is text, so your data gets to be 100 times bigger than storing it in binary. Only 10 times bigger if you compress the xml file. Two orders of magnitude ain't negligible, even with today's fast computers.
Also, I have yet to see an XML parser that actually parses correctly even simple xml files. For example, the MS XmlReader class (in.NET) does not always parse correctly the output of the MS XmlWriter class. Which is giving me enormous headaches at work currently.
Those are just the things I got off the top of my head.
At MIT they make mini gas turbines (basically airplane engines) the size of a credit card but a bit thicker. Imagine the jet-powered laptop if you hook up a dynamo to that.
Apollo did not leave Earth orbit. They just went into a high earth orbit, to rendezvous with the moon (which incidentally is also in Earth orbit, duh). However, the energy (delta v) it takes to go into such an orbit is fairly close to the energy it takes to leave Earth orbit (delta v ~ 11000 m/s)
Just to make it clear, antimatter does have positive mass. Negative mass would mean negative energy. One of the interpretations of quantum mechanics is that the universe is chokfull of negative energy matter and when a particle is raised to positive energy, the hole it leaves in the negative continuum is its antiparticle.
I'm all for taking the task of driving completely away from the driver, and eventually controlling cars by onboard computer, once technology has developed to make this reasonably safe.
We actually have the technology now, but car companies have done studies which suggest that people actually *like* driving on their own. Driving is fun and letting a computer do it is just lame.
If they had depth information in addition to the cameras they could digitally interpolate between frames. Would have looked much better. You're right though.
Those were sweet 17" rims on that GTI. Myself I have the Wolfsburg edition Jetta (the one on the commercial where they are running away from the bear).
Because cancer and aids are not a threat to humanity i.e. they are killing individual people, but are not killing *us*. If we cure all diseases and live really long, we will eventually have to colonize other planets because Earth will not be enough. Better start early than scramble later on.
No, I had Dugan and I think it's Teukolsky in Spring. We use some of LePage's software though for the compuer labs. (BTW I'm not a physics major, just a minor, otherwise I'm CS, just graduated actually)
I thought that all of the new hot superconductors are Type II, partially explaining the high critical temperature. I guess my physics prof didn't explain it well enough or (most probably) I didn't study enough. (I see you are at Cornell, FYI I wrote all that from memory from PHYS 317 which I took last semester).

The image loading/rendering library for Mozilla is internally known as libpr0n. An appropriate name IMHO.

It doesn't promote it. It enforces freedom with the power of the law. Forced to be free... hmm... doesn't sound that good.
ISS costs $60 billion at least.
This is what we use in my company too. (It's a pretty big software corp.)

probably has two cylinders or something.

Head-on at 55 is the same as hitting a brick wall at 110. Tell me which is better?

Wow, you have the spirit of a true experimentalist. Have you considered going into applied physics? I know I have.

They changed the title. At first it was "Pluto no longer a planet" and this is what the poster was replying to.
One person's "anarchy" is another man's "freedom".
The speed of light *in vacuum* is the well known c. The speed of light in a medium other than vacuum is slower by a factor of the index of refraction.
I got 6856 hours and counting...
Not if you use a directional antenna.

It just happened that this is my usual sig, and it's a joke. In this case somewhat relevant.
Nope. Some things don't superconduct. Like gold or silver for example, even though they are the best ohmic conductors.
