Comment Re:Applications? Cooking utensils? (Score 1) 74

In that case wouldn't quasicrystals be useful for a number of friction reducing applications?... On a smaller scale, if paper had a very subtle quasicrystal "grain" embossed or watermarked on it, you would have jam free printer paper!

Or toilet tissue:

Oh, and the main problem I found with Vietnamese notes was the exchange rate, like trying to pay for a 20,000 taxi fare with a 200,000 - quite different!

Comment Re:Physical fractals? (Score 1) 74

You're missing the fractional dimensionality clause and the part about being self-similar at different scales... your description applies to pretty much any lattice not just fractals.

You're right about self-similarity, but I wonder whether quasicrystals don't have some statistical properties that are constant across scales... Actually, I've just googled it:

Self-similarity of Quasi-periodic lattice (Sun Jirong, 1996) : http://cpl.iphy.ac.cn/qikan/manage/wenzhang/0090419.pdf

Quite a mathematical paper. Oh, and this also looks interesting (nice pictures, also):

Comment Re:haskell for the masses? sure, but only... (Score 1, Insightful) 338

I've been programming Prolog quite a lot (a bit CLP too), but still don't get monads, so I just shrug off your snobbish nonsense.

Me either; I don't even think that the higher order concept like monads or arrows are even relevant to most programming. Also, I find actual maths easier to read than Haskell or lisp - it's not just a question of not 'getting' the language; it's not very gettable.

(I hope no-one from lambda-the-ultimate comes across this comment thread or they'll be irritated.)

Right, because every scientific paper, written up in Microsoft Word, w/ inconsistent formatting and font usage, never edited or corrected by anyone but the author, and low-res RGB graphics is instantly and automatically ready to print on a printing press, or to convert to a nice ePub which will re-flow and be readable.

Also, no publisher has ever even considered something like ``The Article of the Future'' --- http://www.articleofthefuture.com/

While there are exceptions (arxiv.org comes to mind), for the most part, raw author manuscripts are _not_ pleasant to read or work w/.

Fair point, but I'm guessing that authors who provide well formatted papers to a journal don't get discounts...

the government is operating almost literally on a month-to-month basis, just barely avoiding financial default and shutdown. Its house majority a collection of pot-bellied reactionary bureaucrats who dismiss everything from climate science to alternative energy and evolution.

But on the plus side, their Slashdot stories aren't accompanied by a Mary Poppins apples and pears fucking cup o' tea shine yer shoes guvnor patronising horseshit fucking telephone booth icon.

Heh, that made me chuckle. What should the icon be, though? A double decker bus, a pint of real ale, a cup of tea and a cigarette? I'm struggling here to think of a symbol that represents all of us Brittanites.

Comment Re:You know how UV light makes your skin turn dark (Score 2) 350

That may be true for non-ionizing radiation, such as visible and IR. However, because UV light is ionizing, the damage it does is CUMULATIVE. I.e., there is no threshold.

Sayeth wikipedia:

Most ultraviolet is classified as non-ionizing radiation. The higher energies of the ultraviolet spectrum from about 150 nm ('vacuum' ultraviolet) are ionizing, but this type of ultraviolet is not very penetrating and is blocked by air.

So, probably okay unless Ultraman wants to look at a strong source in a vaccum.

Haven't you heard? HTML5 and JavaScript are the solutions to all problems these days. Do you need to write an operating system? Just use JavaScript! Did your dog just shit on the carpet? Use HTML5 to clean it up! Did you just drive over a nail, rupturing your car's tire? You can patch that hole with WebSockets! Did you accidentally pour acid on your genitals? Use jQuery to make yourself feel better.

Except don't use jQuery if your page is XHTML, as there is a bug in the latest version (bug id : #9479).

I didn't make any statements that required sources. Also, I wasn't rude to you, but you chose to be rude to me. Perhaps you are trolling, perhaps you are drunk, perhaps you are simply an idiot. Whatever, I'm not interested in anything else you have to say. Continue to piss into the wind if you like, you'll just get wet.

Where in the law-book of nature does it specify things are always required to happen at the same rate? Things often build up over time and then have major, relatively immediate shifts... volcanoes, plate tectonics, plagues and diseases, to name a few.

Nowhere at all. You're absolutely right that there are rapid changes (or 'phase changes' in the jargon of some fields). However, if those happened to ice sheets, we might reasonably expect to have seen them before, right?

Comment Re:"These observations should dispel..." (Score 1) 458

Ice melts naturally as per nature

Sorry to say this, but this statement is nonsense. Yes, ice melts - that much is obvious - but the observation is that it is melting faster than records show. We can't conclusively prove it is humans except by removing everyone from the planet and watching what happens. Since (thankfully) we're not going to do that, the next best proof is to check what happened before we arrived. If there is no other cause - like massive new volcanoes in the pacific or penguins inventing explosives - I think it makes sense to at least look in humanities direction, if not point the finger at us.
