Talk:Ice skating

From Wikipedia, the free encyclopedia

--67.163.43.32 01:06, 12 April 2006 (UTC)Your ice skating article needs to be spell checked and also fact checked. I will revert the changes until you can validate your claims with links to other wiki articles or external links. Friction indeed does increase with increased mass, so do not make such claims. --Benefros 05:19, 11 Nov 2004 (UTC)

If you expect the article to be perfect the first time then you will be disappointed. First step is get the facts right. Second step is to fix up the grammar and the spelling. Third step is to clean up the presentation. That's the wiki way.

[edit] Boob?

The article page says, "Ice skating is a boob...", obviously vandalism. However, when going to edit the page, this excerpt is missing. I don't know enough about wikis to fix this, so can someone else address this? It's been this way for a couple of days.

Wow, that was fast. Thank you!

[edit] What is a Furby?

Is the word Furby in the article a misspelled word? Or does it have some meaning?

Can't see it now, probably vandalism. njh

[edit] Ice Skating

Since when can you not go skating when it's colder than -20 C? Whoever wrote this is completely mistaken because I've personally been skating when it's -25 C. I'm from Edmonton, Alberta, Canada, where it gets cold like that all the time. It might not be all that fun because of the cold but you can certainly skate just like normal. In fact, this winter I'll make a point of skating if it gets down to -30 C or -35 C, and I'll post that it works at that temperature too. I'll have to wait a while for my hands to thaw before I make any changes though.

Perhaps the -20C refers to the temperature of the ice, not the air temp? njh 09:22, 9 February 2006 (UTC)

There's a good review article on the physics by Robert Rosenberg ("Why Is Ice Slippery?", Physics Today, Dec 2005) [1]. He says that Scott's last expedition to the South Pole had no trouble with skiing at -30C, but the snow surface was like sand at -46C. And our article on Scott says:

"The low temperatures they encountered on the Ross Ice Barrier meant that their sledge would not slide easily over the snow in the familiar way. Their task can be better compared to pulling a full bathtub across the Sahara."

Perfect example: The Heritage Classic. NHL hockey at -20 C. (-30 C with the windchill but that doesn't affect the ice) Just what you wanted, another Edmonton reference. Skating is easy at these temperatures.

[edit] Overcomplicated science?

As far as I know, the science goes as follows: Your whole body weight is focused onto a small surface area by the blades. The pressure of the blades on the ice melts the ice into water, reducing friction.

Clausius-Clapeyron relation seems to imply that the pressure theory of ice skating is wrong entirely. Not sure what the true answer is. njh 09:22, 9 February 2006 (UTC)

In his article (see above), Rosenberg explains that the pressure theory fails to explain skating at temperatures below -3.5C. There seem to be two current theories, neither of which explains all the facts. One says that friction melts the ice under the blades, the other that there is always a liquid surface layer at normal ice skating temperatures. Incidentally, other substances such as lead also have a liquid surface layer when slightly below their melting temperature. (Diamonds too.) -- Avenue 11:09, 21 February 2006 (UTC)

Please also see this link: "Dr. Salmeron said that this finding indicates that while the top layer of ice may be liquid, it is too thin to contribute much to slipperiness except near the melting temperature.". Don't know the truth, either. Fuss 18:36, 21 February 2006 (UTC)

Maybe ice skating is impossible... I know that bumblebees can't fly, you can't burn boats with mirrors and nobody could have built the pyramids :) njh 22:52, 21 February 2006 (UTC)

im an ice skater peronaly and i skate indoors in a rink yay

[edit] Rousette Skating ??

What on earth is Rousette Skating? I really think we need to add more detail, or remove it. Maybe it is related to schoonrijden? Gary van der Merwe 18:46, 18 September 2006 (UTC)

I created a stub article, but when I added the wiki link, I did't find the word from dictionary, therefore the term might be wrong. Or another possiblity is that there is no English term, but that event is a pure Finnish origin. --Thv 14:53, 19 September 2006 (UTC)

Cool. Very interesting. Gary van der Merwe 15:16, 19 September 2006 (UTC)

[edit] Ringette

Shouldn't this article have a link to ringette? Meters 00:31, 22 February 2007 (UTC)
