    I shot the skaters with a Phantom MIRO LC320S made by Vision Research:

    Most speeds were around 1750 fps, but I shot the Hocket skid at closer to 3500 fps.

    Glenn Replogle, the Figure Skating and Hockey Player coach was great to work with. Also, a big thanks to Glenn for helping me borrow two skates from the Huntsville IcePlex. www.iceskate.org/
    Nick Laurila was very helpful and accommodating. We also became friends pretty fast. It would bring me great joy if people reading this video randomly years into the future would randomly tweet hot dog photos with the words "Here's a Hot Dog on @SmarterEveryDay" to him / nick_l12 . He has reminders setup in his phone when local fast food chains have "Dollar Hot Dog day". It's quite funny, but deep down I'm jealous of how clever it is.
    Robert Farrell answered my Facebook appeal for Photographers/Videographers in the Milwaukee Wisconsin area and filmed the skaters at the Pettit National ice Center for me.

    With thanks to:
    JR Ginex-Orinion - he helped me by putting the equation in LaTex and giving me a file. This saved me a lot of time and I'm grateful.
    Kevin Butler at the Pettit National Ice Center in Wisconsin was helpful in coordinating the filming of the speed skaters.

    When Destin mentioned the physics going on in the players’ brains, he wasn’t saying that they were consciously doing math equations in their head, rather that their brain can subconsciously calculate the exact angle, velocity, speed, etc of all the maneuvers fast enough to keep up with the game.
    I think his point was that, while they may not consciously understand the math, their brain can calculate everything just fine, showing how powerful the human brain is.

    You bring up an interesting point regarding the “background” processing of a hockey player’s brain.
    Wayne Gretzky was not the biggest, strongest, or fastest player in hockey. Far from it. But he had an uncanny ability to predict where a play was going. He was almost prescient in that regard. It’s also why he was such a prolific playmaker, even long into the twilight of his career. He could make passes through loads of traffic because of whatever background geometry/physics processing going on in his brain.
    Hockey is pretty unique among the major sports because of Gretzky. Typically the best players possess some ungodly physicality. Look no further than someone like Lebron James. But Gretzky was a reedy, average sized kid who absolutely dominated the game because he quite literally out-thought his opponents.

    • @CBotts81

    • @NWProductionsHD
      @NWProductionsHD 8 років тому +143

      +flij yes but you also internalize all the angles and speed you need. Think back to when you first started skated, you could barely push off, let alone stop - definitely not stop of a specific point. Hockey players like to simplify stopping to leaning into it and that's it. But there's really multiple stages where the blade acts differently in each. You need to remember how to adjust on each of these stages to stop precisely where you want.

The melting of ice under the skate isn't due to friction, but regelation, the decrease of the melting point temperature in greater pressure (because of the special thermodynamical properties of water). It's why glaciers move, and why a rope can go through slowly a block of ice, without cutting it in half.

    I love that sharpness diagram! I use it all of the time and I never knew you guys made it! Also, goalies tend to sharpen their skates to have more bite because we have to be technical in our movements in order to position ourselves to stop the puck. The skaters tend to have less bite because, well, they skate more. It helps them skate faster and they don't need to grip the ice as much as goalies do.

I have lived in Florida for 51 years after spending the first twenty years of my life mostly in the frozen north, Canada - ice skating on the Rideau Canal in Ottawa to work at one end and attending classes at the university at the other end. I was SO thrilled when somebody invented rollerblades and was able to carry on my dream to the closest thing to ice skating I would be able to find in a tropical climate.

    My chemistry teacher always told us that ice skates work not by friction, but because of the pressure of the thin blade on the ice. According to her, water is the only element that actually expands as it becomes a solid, therefore when pressure is put on the solid it forms the layer of liquid water you mentioned. Is this actually true or is it just the friction, or maybe partially both?

      It's a common misconception; in fact, ice has a layer along the surface where the crystal structure can't form properly, so it's still sort of liquid. This layer is only a few molecules thick, but it's enough to create a low-friction surface on the ice.

    As far as friction melting goes, I’ve always believed that the melting was from pressure. We know that water expands as it freezes. That makes ice less dense than water. Conversely, compressing ice increases its density, which causes the phase transition back to water.
    Water is unique in that in its solid state it becomes less dense, that is why ice goats in water.
