It is truely sad the US is losing world class scientific research to other countries. Granted other countries actually fund pure science at a much higher rate of GDP because the majority of republicans view science as witchcraft.

Cool, one step closer to the Star Trek replicator, just have to figure out what to do with the anti-matter copies.

Star Trek gave them goatees.

They immediately die, well explode but the end result is the same

I was told there would be no mass.

I know who the square is here, and it ain't matter.

I just don't have the energy for this.

Not really

Ugh.  Campfires DO NOT make energy from mass.  They release energy stored in the chemical bonds between atoms.  No atoms were harmed in the making of your smores.

This writer sucks hard.

The change in bond energy does result in a very slight mass difference between the reactants and the combustion products.

I thought total mass could not be changed in non-nuclear reactions.

I had a nightmare last night in which a female character said "I'm like the square root of two, unending" and dream me replied "no, you're just irrational!"

Maybe if everyone else viewed science as witchcraft it would be more popular and recieve more attention and funding!

It depends on if you think light has mass.

It depends how many decimal places you use when measuring it. If an atom of Uranium-235 splits into Cesium-137 and Rubidium-96 plus 2 extra neutrons, there's no change in mass if you're counting protons and neutrons as each having a mass of 1 unit. If you do look in more detail then you'll find that the mass decreased slightly, corresponding to the amount of energy released in that reaction. The same thing applies to chemical reactions but the amount of energy in chemical bonds is so small compared to that in nuclear bonds that it's only a theoretical change, not something you could easily measure.

As long as those Rimmers do their jobs.....

I learned something tonight. This just got well beyond my introductory Physics class from back in the day.

Thanks.

In the Czech Republic.  Check out their expenditure on science

I was going to bring a Yahoo Serious Young Einstein "Split the Beer Atom" joke to the thread.

But a quick image search shows that would probably be taken badly

Define the speed of light as 1 and they are equivalent.

Thought we had this laser light generation of stuff figured out by now. :)

Not if you're working in Planck units.
