    Art Atlantis' Existence and Place On Earth

    Well he passed away a few years ago, and his day job was physics professor. It seemed strictly a hobby and not a money making scheme. The checklist was based on Plato's description. But don't you find it interesting that such a large area of habitable land was flooded around the time Plato claimed?

    Graduate Has C ever been derived from knowing E & M?

    Well, thanks for that great answer. But I am curious to know how many decimal places that the derived speed of light differs from deriving it from the measured mass and energy. If e=mc^2 is correct, then deriving each variable from knowing the other two should give you a measure to how well...

    Graduate Has C ever been derived from knowing E & M?

    I think that deriving C from a measured value of E & M would help prove that no unknown forces acts upon the speed of light when we conduct terristrial laser light speed measurements.

    Graduate Has C ever been derived from knowing E & M?

    Looks like MIT did something similar here solving for M. But they plug in the same old derived value of C and never solve for E. http://web.mit.edu/newsoffice/2005/emc2.html

    Graduate Has C ever been derived from knowing E & M?

    Obviously no one has ever converted 10kg of mass into pure energy and measured it. Have we ever been able to convert a known mass into energy and accurately measure that energy output enough? I want to know if C has ever been independently verified based solely from M & E measurements.

    Graduate Has C ever been derived from knowing E & M?

    Ok, I know e=mc^2, so c = √(E/m) I know we usually use fancy laser setups to measure how fast it travels in a vacuum, but has c ever been accurately derived from knowing e & m?

    High School Does a bullet fired with a clockwise spin travel faster or slower

    No, stopping power is determined by how much energy is transferred from the projectile to the target. It is affected by both the mass and velocity of the bullet, as well as to how it behaves when it strikes the target.

    Undergrad Shouldn’t ice on comets burn up quickly?

    Comets have enough gravity to trap some of the surrounding water vapor. Once it cools (comet moves away from the Sun) it could re-accumulate on the comet.

    Graduate Lone wolf planets able to support subglacial ocean life?

    If the planet has a sufficient internal heat source then perhaps though extremely unlikely. Even if the Earth lost the Sun, I'd think there would be sufficient internal heat that volcanic vents or something similar could support life until the Earth cooled enough.

    High School What are the shapes of orbits that exist in our solar system

    Extremely complicated :biggrin: Every object in the solar system (and some things even outside the solar system) influences the orbit of every other object. Normally these object have to be big, but when you consider the nine or so planets, and the moons orbiting each planet this has to be...

    Where Do Black Holes Go After They Form?

    A Blackhole is only theorized to be a singularity, it's not a decided fact.

    High School Does a bullet fired with a clockwise spin travel faster or slower

    The spinning stabilizes the bullet, because it is stabilized (not shaking, vibrating, tumbling, zig-zagging, etc.) it cuts a path through the air that offers it less air resistance.

    High School The Fascinating Possibility of Reversed Earth Rotation

    Stand at the North Pole, then stand at the South Pole. Does the Earth seem to be rotating in the opposite direction? :bugeye:

    What do you think of the Cartoon Guide to Physics?

    What do you think of the Cartoon Guide to Physics? I read it in the early 90's and was quite impressed with how well it explained how things work. Should be required reading for all non-science majors. Hell, I'm not convinced that all art majors buy into this whole round Earth "theory" :wink...

    Graduate Transfering Electricity w/o Medium? (Electron Beams?)

    Congratulations, you just invented the cathode ray tube :cool: http://en.wikipedia.org/wiki/Cathode_ray" Here's a general article on wireless power transmission as I bet that's what you are really curious about :wink: http://en.wikipedia.org/wiki/Wireless_power_transmission"
