  1. This changes the meaning. Not illogical to exist, does not mean something logically exists.
  2. I think it is as much to do with "when and how many", which is interesting.
  3. Looks like it could work... for one cycle, since you start off with helium at 200 atm, possibly a second cycle at lesser output, using the room temperature air as a heat source and the cooled helium as a sink, maybe a third or fourth at less and less power and less and less efficiency. After that, from room temperature air as the energy source, and no sink ...not so much, it will come to halt. Something like this could work from solar energy, but not at the efficiencies or outputs implied
  4. I won't comment on the "brainwaves" part, but otherwise it is obviously not illogical or impossible, unless it is impossible to biologically duplicate the basics of a cell phone. Somewhere in the Universe, some species likely uses telepathy IMO. So for my part, I will agree it is not illogical.
  5. How would you ascertain that they scared the cows then scavenged vs simply scavenged?
  6. You have a reduction in kinetic energy available as well, for the second set and for the first set of blades as well. The first set is in reduced flow due to the second set. The second set is in reduced flow and turbulence due to the first set. So you probably have greater inefficiencies than one set of blades alone.(less available power)
  7. Tomorrow I will buy a sandwich.
  8. Thanks.
  9. I will say yes, definitely. Is Pharmacology a science? Psychology? How about the study of the Origins of the Universe? All of the above have limits to how rigorously they can examined, making it hard to separate the wheat from the chafe, good science from bad, but are they not all science?
  10. Why another Universe? If the loss and gain for our Universe is equal...
  11. Any Aether theory?
  12. This guy was the first to make the measurements back in the 17th century: http://en.wikipedia.org/wiki/Ole_R%C3%B8mer
  13. 5) is interesting. Large areas of half time land / half time sea (and all other ratios between low and high tide) might certainly help transition from sea to land as well as force bio-diversification.
  14. Keep in mind that the spring is in all inertial (and other) frames at all times, although it is always at rest in just one. It is not doing a dance to keep them all happy. It simply is measured differently in each frame.
  15. I find it a lot easier flying West a few time zones. Adjusting is like staying up late but getting to sleep in. Coming back East is a much tougher adjustment.
  16. There is friction, and other mechanical efficiency limits, but also the pistons are "running away from" the forces that are powering them. It's much harder to push with force against something that won't resist, and it's the force on the pistons that produce the torque.
  17. Multi blade props have more "sail area". That sail area can develop more torque than less sail area. When the prop speeds up the blades are interfering with each other, there is not enough energy to go around. 2 and 3 blade props are all that is required to get the maximum energy from the swept area of the prop.
  18. As measured from the Earth, the twin expands in the direction of deceleration until he is at rest in that frame.
  19. Couldn't afford a ticket?
  20. It is common in the inverse. velocity in meters per second acceleration in meters per second squared or per second per second jerk (change in acceleration) in meters per second cubed or per second per second per second
  21. IMO, if there is an aether, or whatever you want to call it, whatever it is has to allow for length contraction. The old aether didn't do that.
  22. At any given rpm those are the maximums for torque or power. At higher rpm the engine cannot continue to maintain greater torque. Only reducing the load will allow the engine to achieve higher rpm, so the torque must fall off. The power output continues to rise due to the greater rpm, until that reaches a maximum as well. At highest possible rpm (not shown, it's off the graph) there is no torque or power output at all. (though you could get some instantaneously from the momentum of the engine)
  23. This is true at any given time, or point on either curve. The power is the torque times the angular velocity. The graph shows the horsepower the engine is capable of at a given rpm, and separately the torque the engine is under at the given rpm and horsepower, but with no numbers to indicate the actual torque (the scale on the right indicates horsepower only).
  24. It is not necessary (or even a guarantee of stability) for the center of buoyancy of an object to be above that of the center of gravity for it to be in a stable floating position.
  25. Unless you add ballast, which could be water or a weight, the shape is not stable. The righting arm from the changing center of buoyancy does not change fast enough, even at small angles of "heel", to counteract the "tipping moment" that is created. http://en.wikipedia.org/wiki/Metacentric_height
