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.
Music made by Gordon McGladdery, "A Shell In the Pit".
Gordon's work is awesome, you should check it out.

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.
He's a photographer www.robertfarrellphotography.com/
-------------------------------
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.

@NWProductionsHD
@NWProductionsHD 8 лет назад
+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.

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.

+SmarterEveryDay Hi there! Small correction to an otherwise super video. 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.

Adam Wojtczak Insects do complicated physics calculations as well however they use very specialized processors to do so and due to this fact they get more done with smaller processor. Hockey players DO complicated physics calculations but they do them using part of the brain we call subconciousness and precalculated values (Center of mass, weight of their limbs, stregth differentia of different muscles that have been figured out over years and stored at readily available memory registers for subconciousness) and thus manage to do it efficiently on the fly.

My favorite thing to do in life was ice skate. It felt like it was the best sport with the less friction/contact between me and the ground or water. But your video is answering all the why's. 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. Thank you for the video.

First time I went ice skating, I sucked, because I tried figure skates first. it was awful. Tried hockey skates, and I easily picked it up...Just like roller blades. I roller blade very well, but can't use quad-skates for my life =P Also, most hockey players are very smart. A lot of them go to high end colleges, the goalie of our local ECHL team, had a degree is accounting I think. And that's not uncommon. They're also the athletes you hear the least about..you almost never hear about 'scandals' and/or crime when it comes to hockey players.

i understand that there is math and complex calculations involved in everything, but i'm pretty sure large majority of people are thinking little to none of that when it comes to doing things like ice skating. It's cool to know the math and science of whats really going on, but not necessary to do it, pretty sure most of them do it by practice and feel, not "hey if i turn my legs at this specific angle and apply 30% power to my left leg, then i should be able to turn quicker and come out of that turn at such and such a speed".

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.

@zacharyweiner2152 10 лет назад
Skates generate a large pressure on the edge. Ice is less dense than water (why it floats). When you increase the pressure enough, you force H2O to go into its most dense state, which is water. That is why there is a layer of water you glide on while ice skating. You may have also had a science class that "boiled" water at room temperature by putting it in a vacuum - same concept.
@rsajay6256

"Audible Hopes You've Enjoyed This Program" Also, as a hockey player... Ermm, I mean a club level superbike racer, we don't think about the physics involved with backing it into a corner either, one simply (yeah I know, one does not simply, one will half-kill ones self spectacularly) learns by repitition where the traction of a given part of a given turn's entry is, and by gearing down faster than one should and dragging the clutch more or less right, the rear tyre's resistance via the slipping clutch and engine braking, fractionally exceeds the friction between the road surface and the contact patch. This allows the bike to back in or "feint" in to use the car drifting term, and be steered from the rear with a balance of ever decreasing front brake pressure, and clutch slip. The braking trail off is a discretionary, sometimes you may need to still be trailing a little front brake sometimes not. Likewise feathering the throttle all the while, and then going positive throttle to actually increase rear tyre spin on exit as you're standing the bike back up, gradually so that when the rear tyre hooks up once you're upright, (larger contact patch toward the sole than in the tyre shoulder increases grip suddenly) and you are shot off down the straight, is also a learned skill. Much I imagine like hockey players don't think about the physics, they feel the skate blade shaving the ice and know how it normally behaves. Need to stop later - less shave, need to stop sooner, more shave. And... just like a bike, too much and you slide out. Too little and your slide hooks up and you sort of shoot off in an unplanned direction, and either get some airtime before gravity brings your clamping angus back down on the seat, or you highside and do the ragdoll, maybe get chewed by your bike
@deadpanfish

Do you think it adds an advantage to know the physics, in either racing or hockey? I mean if you can understand the science I think it would work to a greater advantage having the physical muscle memory, but also an understanding of your motion at a greater extent. Although, being an athlete, the last thing you want is to be doing calculations while trying to compete live. That's why we practice. A lot. Sad to see all these nerds in the comments thinking hockey players are just a bunch of meat heads. To be fair, a great bunch of them are. But you'd also be surprised. Peace
