the amount of money that goes into such efforts to go to other planets is outrageous! for the amount that is spent on space travel could be used wisely to pay off the U.S. national debt, help the poor, build better schools, better hospitals, etc. Does any one else think the money could be better spent??
we, the people on earth do a good job destroying this planet, why ruin another???

A rock is dropped from rest into a well. (a) If the sound of the splash is heard 2.40s later, how far below the top of the well is the surface of the water? The speed of sound in air (at the ambient temperature) is 336 m/s. (b) IF the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated?

From what I've read, quantum computers will be very fast but basically use the von Neuman architecture. I wonder if there could be a quantum neural net instead, and if so, what it would physically look like: size, parts, special needs, such as will it require supercooling or unusual power supply; will it incorporate an NMRI device, etc. The neural net question relates to whether it would need to be programmed or could it "learn" and eventually act as, say, an expert system. Would it occupy a large room or a small suitcase? (I'm not trying to build one, just to describe it for a fictional piece.)

Does anyone else think that the television show Mythbusters practices the worst type of science out there? Every episode I see them not practicing even the most rudimentry aspects of the scientific method. They rarely use controls and their experiments always have variables that they either overlook entirely or put into the project without thinking of it. They even give out flat out WRONG info on the program. I've seen an episode where they were shocking eachother with electricity and said that " There is not enough current to be deadly". Don't they know that a current of even .5 miliamps can be deadly to a person? I mean comeon it seems like these guys havn't even taken physics 101!

Any help on this problem would be greatly appriciated!

Objects with masses of 290 kg and a 590 kg are separated by 0.420 m.
(a) Find the net gravitational force exerted by these objects on a 36.0 kg object placed midway between them.
Your answer differs from the correct answer by orders of magnitude. (N)

(b) At what position (other than infinitely remote ones) can the 36.0 kg object be placed so as to experience a net force of zero?
(meters from the 590 kg mass)
