Diamond the strongest stuff? I'm quite certain fullerenes have been made to be stronger.
Diamond has lots of hardness (scratch resistance) but not much toughness (impact resistance).
Which they say in the article >.>

Actually that's what I meant. I can't remember where, but I read somewhere that a fullerene has been made that can (relatively easily) scratch a diamond.

It's actually funny: diamonds, fullerenes and graphene are all hard... But graphite is close to the bottom of that, as I recall.

That is because graphite is basically just a stack of graphene sheets with very weak forces holding them together.

And a molecularly thin sheet doesn't have much fluxural strength when compared to other materials which don't have that problem.

A weird thing about graphene sheets is I can't remember, but isn't there something about their electrical resistance that's just an absolute wonder?

Probably you could have googled it and clicked the first link which is wikipedia's entry which is here.

In summary: Graphene sheets have the lowest resistivity of any substance known at room temperature.

True, but it's at least cited. (https://newsdesk.umd.edu/scitech/release.cfm?ArticleID=1621)

I don't really mind all that much, just saying. :)

Carbon nano-tubes are soooooo last season :P

It's all about compound allotrope's and semi/super conductors now xD

Unlike an article on a christian "bash anything I dislike" site which decided to bash Skyrim claiming it "turned people gay."1  The author (in a reply to a comment) sited his claim that Americans don't speak English by referencing his own blog.

Wikipedia you can be fairly sure of it's accuracy by checking to see if a claim has a source and then checking that source.

1 The entry was so poorly researched, claiming that Blizzard produced the game.  Among other things, of course.
