Some of you may be confused why I listed one of the keywords being foreignaffairs, well, years ago I was a weekend-warrior and I was tentatively assigned to PCS to Alaska should hostilities have broken out betwixt the U.S. & the former U.S.S.R. So it shouldn't really be all that mysterious: ice, cold-war, Alaska, get it?

Then I was going to post it in culture/philosophy because I have the "Yer Album"

Being a veteran Freep-poster, I understand it is extremely bad form not to perform the perfunctory search to see if its already been posted. Much to my glee I discover that nobody has posted this cool little tid-bit. Moreover, I discovered Blam's post about the same way cool topic as mine.

Enjoy!

I'll tell y'all one thing: ice is one facinating substance. It is simultaneously the blackest and whitest body known.

It is the whitest substance known in that its albedo is uniformly high across the whole spectrum (reflecting all electromagnetic radiation with equal vigor), however, it absorbs IR like nothing else known (and so is a perfect blackbody. Its plausible that I could be wrong on all that (considering that I'm self taught on all that). But that notwithstanding, water is some pretty wonderfully facinating stuff.

E.g. if but for that little density hook thing, no life on this planet could exist (all the lakes would freeze solid ffom bottom up). I'm certain this would cause no shortage of consternation to would-be ice fisherman.

I don't skate but both of my kids play ice hockey. They talk about 'soft' ice & 'hard' ice...soft ice is slow, hard ice is fast and they get their skate blades ground accordingly.

Yea, but you do realize it contains the deadly, corrosive substance monohydrogen dioxide, don't you?

A typical blade edge, which is not razor sharp, is about one-eighth of an inch wide and about 12 inches long, yielding a surface area of 1.5 square inches each or 3 square inches for two blades.

Figure skates and hockey skates have a curved blade. The pressure exerted by them would be much higher, due to the much smaller surface area in contact with the ice. I'm surprised these scientists either don't know this or failed to mention/consider it.

Yes, ice is slippery even in contact with shoes. But compare the two. You will travel much further gliding on ice skates than you will in your wingtips. There seems to be something to the pressure and/or friction angle after all.

The original title for the article is: Explaining Ice: The Answers Are Slippery. Why did you change it?

Anyone know where one can find the dozen 'forms' of ice's details? Sounds kinda fascinating

What I want to know is why A&W rootbeer doesn't taste like it used to when I was a kid.

The ice in the Olympic rinks is pretty thick. You won't be in danger of falling through it.

So you're probably wondering why I have this limp...

See, I meet Old Scratch and say "I'd sell my sole for the ability to be unbeatable on ice - figure skating, hockey, whatever I choose"...and he says "Sure, sign here," and so I do...and he starts laughing and laughing, so I challenge him to a face off on my frozen-over sidewalk, and he kicks my butt, and I say "You dirty welcher!" and he says "Hah...you didn't say what KIND of ice - you're only invincible on Ice VII, the kind we have in Hell!!" and I say "Well, I'm not a bad speller, you vomitous mass, I really did only offer you the bottom of my foot, like I said before..."

so now I limp.

Did you ever think how fortunate we are that water's not flammable?
