What are examples of turning energy into matter?

Patrick Poisson  asked the Naked Scientists:
   
The sun and nuclear bombs are examples of turning matter into energy.

What are examples of turning energy into matter.  Will differing energies yield differing matter, or will it only produce hydrogen which would have to undergo fusion in order to form other matter, or would the matter produced be simply elementary particles?

What do you think?

One of the most simple ways was described by lightarrow in another thread. Simply place a piece of dark paper in sunlight. Mass is created in the paper as it warms.

Let us be clear here Patrick.
What my esteemed friends Vern and Lightarrow discusses is mass.

Specifically 'invariant mass'.
What you, on the other (and third tentacle) refer to is matter.
And I guess, that as me, you fully expect this newly 'made' matter to 'stay' once created?

To bring more energy to a object is one thing, creating a paper more beside that first one is something entirely different.

Particles is what you are thinking of, right. those sneaky bastards hiding behind their friends, that brotherhood of vacuum.
Considering that they for 99.99999 percent doesn't exist, right.

Lightarrow, Vern, wanna step forward do defend your 'paper' now huh:)
I say, vacuum is the masters of the universe:::)))

Hi yor_on, I glean from your posts that you want to ascribe a different meaning to mass as opposed to matter. We use the same units of measure for each. I don't know how we can see one as different from the other. Dr. Robert Kemp in his paper linked here says that mass is electromagnetic change. It is the first definitive answer to the question "What is mass?" that I have seen.

So if Kemp is right, all we need do to create mass is to confine energy into a local system.

In answer to Patrick's question, so far as I know, we have been able to create massive particles by concentrating huge amounts of energy into small spots. So far we can make electrons and positrons. Maybe the Large Hadron Collider (LHC) will make more massive particles. Or maybe I should say; make particles that are more massive.

You can create particle/antiparticle pairs as long as you have enough energy, e.g. 1.02 MeV for e-/e+ pairs

Nope, 'matter' is not 'the same' as that sun on that paper.
Its 'constituents' may be the same, but its state is unique.
And that I will proclaim :) at the top top of my lungs, until my last breath.

Which should be fairly soon, if I continue shouting like this:)

Hi yor_on; I know that you want matter to appear as another piece of paper; not just the same paper that weighs more. :)
