Originally by: Deathbarrage there's reasoning for each damage type, there's also enough reasoning that kinetic and thermic is the same since thermal energy is just moving particles... won't happen
A discussion on this with my friend who studies Physics. (I know it's only pseudo science in Eve, but still...)
Friend: you can't equate the macroscopic kinetic energy of an object with the kinetic energy of the particles that make it up Friend: the internal energy of a thermodynamic system is comprised of kinetic energy due to the rotation, vibration and translation of its particles; and potential energy due to the atomic forces in those particles themselves Friend: those are not equivalent to the kinetic energy of the complete system due to its motion through space Friend: put it this way, you can't cause a macroscopic object to move by hitting it with a laser beam Friend: therefore it has no kinetic effect Friend: you can *just about* manipulate microscopic glass beads using carefully controlled multiple femtosecond laser pulses, which is what a lot of people spend a lot of time doing in St Andrews Me: Can I quote you? Friend: he's quite right in saying that it imparts kinetic energy to the ship, but only by causing the molecules to vibrate Friend: and guess what that is Friend: heat! Friend: go ahead
then to your friend
Laser = concentrated light
solar sail = Spaceship using a thin foil sail to catch light particles from the sun (AKA photons) and use this as propulsion to achieve sub-light speeds.
Equals the solar sail is being pushed by a laser
yet your friend just said otherwise
even though this technique is being used by NASA
weird
As a point of order:
http://en.wikipedia.org/wiki/Solar_sail
The kinetic energy imparted by a single photon is, well, negligible. You don't feel photons striking your skin as an impact, you feel it as heat (if it's substantial enough to feel it at all).
I'm not trying to make trouble, but even a solar sail, designed to "catch" the solar wind, is impelled along slowly.
Light lacks the kinetic energy, even in a cohesive form, to "strike" an object like a rock might strike a windshield, or an apple might strike your head.
Just adding a few thoughts, I would fully support some sort of change to Lasers damage type. ECM Specialist
