The 'show why science is awesome' thread:

[quote]This car race involved years of training, feats of engineering, high-profile sponsorships, competitors from around the world and a racetrack made of gold.

But the high-octane competition, described as a cross between physics and motor-sports, is invisible to the naked eye. In fact, the track itself is only a fraction of the width of a human hair, and the cars themselves are each comprised of a single molecule.

The Nanocar Race, which happened over the weekend at Le centre national de la recherché scientific in Toulouse, France, was billed as the “first-ever race of molecule-cars.”[/quote]
I look forward to the inevitable sponsorship of nanocars, although I suspect Viagra and Cialis may pass on this opportunity.

Gene editing at work. CRISPR has really high upside, and also is really scary. Hopefully it continues to be used for good.

Check out top left and middle bottom. Nano-wangs!

OK, this is truly weird.

I don’t even begin to understand what goes on these sort of cutting-edge quantum experiments, but it sure seems neat. What kind of crazy stuff is this leading to?

Ansibles!

I’m reading a science fiction book based on quantum messaging that explores things a bit. Being fiction, I’m not sure just how much I would lend to it, but one of the effects of quantum communication is that time is not a factor either. The book explores messages to the past.

Related to this, though, the beauty of quantum messaging would be that it is faster than any method among methods. Faster than light, via superluminal communication.

So the fact they pair this on top of light waves makes me think this is a step … back? Either way though, quantum mechanics is extremely interesting.

Well said!

Er, I think this might be a spam bot. A few posts, mostly product recommendations and this is straight from this lecture here:

But was it quantum posted in the past, or the future?

It’s complicated, this will explain it:

Interesting. So where did this come from?

Clever bot programmed to respond to replies with simple language replies of it’s own? I am by no means an expert in the design of bots, but it seems plausible, particularly as an actual reply would notify the bot and prompt a programmed response.

Seems the posts have been removed now. I am always wary of very new users bumping very old threads (as he did in the chair thread) with a random product recommendations and little in the way of exposition in any post anywhere.

Understood. You bring much honour upon our simple forum. :)

;)

Why is only part of that in quotes?

That’s what you get for copying and pasting a meme some other dude on the internet made, I guess.

Would any of the physics trained board members care to comment on this paper about vacuum energy driving the expansion of the universe?
