Theoretically, of course. If you slammed the graphite REALLY hard onto the diamond, could you break the diamond as well as the graphite?

our modern space probes take about 9 months or so to get to mars from earth. that's long. I know it's far but why don't they use more propultion up there. there's no cops, no speed limit (except light speed), no friction. so as long as the gas peddle is pushed, the ship accelerates. why not give it some gas, slingshot around the moon like in armageddon, and do capt kirk a solid and hit warp 1.1 already. at the current rate, it takes too much of an astronaught's lifetime to make it worth going anywhere significant like the moons of jupiter, saturn, uranus, and neptune. these moons are not just dead rocks like our moon. they have volcanism, no not like Spock, but volcanoes, geisers, glaciers etc. but it takes a decade to get there. we need to move faster in space in order to do anything outside of our solar system. there are billions of other suns in our galaxy alone. some of them probably have big chunks orbiting them as well like our planets. we might find suitable planets

If only "sensible" results of measurements can be observed, how do atomic scientists verify wavefunction states of a phenomenon like a half-live and half-dead Schroedinger's cat? I remember reading that the analogy applies to semiconductor circuits, where a gas exists on both sides of a barrier until it is observed. How can this be known with certainty?

Could anyone help me on these two questions?

1. Convert into cartesian form

r(1 + sinANGLE) = a




Also

2. What is the largest possible domain and corresponding range for the function :

y = 1 + x + x^3

Any help on either would be appreciated

haven't taken any course in quantum field theory or read any advanced books about it, but I would like to make what I think is a deduction.

An electric field can be explained by changing magnetic field. Provided that some property of this changing magnetic field was met, the electric field may correspond to the electric field produced by a subatomic particle. So far, I don't know of any other type of field that would generate an electric field other than a changing magnetic field. Do the quantum physicists explain the electric field of subatomic particles this way? Do they know the changing magnetic field that would be necesary to generate the electric potential of the proton for instance?

I am confused. Is the Lansdowne Resort in Lansdowne VA or Leesburg VA? The hotels website has contact info that says Lansdowne, but other places say Leesburg. It seems like these two places fall in the same zip code too.

Here is the question...
Two fire look out stations are 20 miles apart with station B directly east of station A. Both stations spot a fire. The bearing of the fire from station A is N60 degrees east and the bearing of the fire from station B is N40 degrees west. How far is it from Station A to the Fire?


In miles..
This is a multiple choice
a) 7.5 miles
b) 1.5 miles
c) 16 miles
d) 10.2 miles
Thanks for any help you can give..

properties with much stronger anti gravity generators. Now take these two and align them both on giant rings in about, say the outer ring is 5 miles in diamtr. and the inner ring is 3 miles in diamtr. You array your singularity and anti gravity gens. staggered from each other on the inner ring facing out and the outer ring facing in. You would then counter rotate them to produce a black hole ring, with the anti gravity gens. propelling the singularity ring away from the inner ring at an angle to permit passage though the center. The field is stable and you have pulled space and time from two separate points in the universe to one location at the ring of the singularity. Theoretically you just simply fly your craft through the opening in the middle and be billions of light years on the other side of the universe right. But you flew a safe distance out and away from the singularity ring and went around to the back side of where you know the rwas placed. Would there be a ring there???
