Why only particles of micrometer sized scale and above?
It seems very strange to me why there should be a limit at the micrometer sized scale. I put a {{fact}} tag after that sentence. Discussion for the tag goes here. —Kri (talk) 14:14, 20 August 2012 (UTC)[reply]
Okay I see there were not much of a discussion. Maybe it's better to just remove uncited, dubious statements directly, like Glrx did. —Kri (talk) 13:38, 22 August 2012 (UTC)[reply]
It's good to discuss issues on the talk page, but WP also asks editors to be bold.
If an a statement might be true, then quickly look for a source. If you don't find a source, then tag it with cn. Statements tagged with cn can stay around a long time. If a statement is doubtful, then tag it with dubious and explain. A dubious statement should be removed if a source isn't provided within a reasonable time. If you believe a statement is wrong, then remove it.
For me, the statement seems clearly wrong; one of my professors was doing discrete element simulations of galaxies long ago....
Others simulate atoms in UHV or electrons in orbitals.
