Is this paper trying to say that dark matter is actually baryonic mass?

Allaboutcircuits.com has a great E-book, and very good forums on the topic, check it out.

There are many DC-AC converters designed specially to run from a 12v car battery. I find it really usefull to have 110v AC outlets in my car. It costed me around $30 for a 400W inverter.

There are a few companies developing Exo-skeleton suits. I've seen the Raytheon (named XOS) suit in a few videos.

Besides the Temperature increase, there is a very high increase in the 'n' of the equation -number of moles-. The gasoline enters as liquid and changes into gas.

Expanding cjl's post: 30000N=15000kg*2m/s^2 is wrong; while F=15000kg*(2m/s^2 + 9.8m/s^2) is the right expression.

Anyways, applying the concept of Schwarzschild radius to an electron seems pointless. EDIT: It appears it's not entirely pointless. There's even http://en.wikipedia.org/wiki/Black_hole_electron"

Maybe when considering a single photon one would have to consider solid state physics and phonons? (I'm just thinking out loud)

1. "...in contact with an equal and opposite force" to what? the object won't stop unless a there is a force that causes it to decelerate until it stops. 2. No, it will keep moving at a constant 100km/h. Remember that acceleration involves work and energy, so nothing accelerates unless...

When you say de Broglie you mean the 'simple' \lambda = \frac{h}{p}?

So to resolve this scenario one needs complex math with Hamiltonians? Isn't there some simple math for it? I was expecting a very straightforward solution.

Hello. Consider 2 spacecraft isolated in space, with a mirror on their back, facing each other. One light pulse is shot between them. The photons reflect off the first one, transferring a momentum off 2p, travels in the opposite directions, reflects off the second spacecraft , giving it 2p...

You are trying to add apples and oranges. Kcal is a unit of energy, while pound is a unit of mass. For determining how much weight in the long run a person will gain after consuming X kcal you would need precise data on his energy consumption.

Open system exchanges matter and energy with its surrounding. Closed systems exchanges just energy with its surroudings; e.g a Thermos An isolated system doesn't exchange anything with its surroundings. Its like if it were alone in the universe.
