How to XCD on NNN/SNS?

[Raventele]

I am not confused at all.. The "force" is going to end up being muscular and skeletal..the force must vector the inertia /momentum of the skis ( and the skier's mass as well) ..may the force be with you.

Actually the force that accelerates you toward the center of your arc is the reaction of the snow on your skis. I wasn't arguing with you, for the most part, your notion that changing momentum is what is really happening.

I think what he meant by force on the boots was drag/friction/mechanical loss from the interaction with the snow.

And as for the second robot. Those look like wedge tele turns to me. It's a stem, snowplow, or wedge with the tele stance.

Interesting!
His style seems to be a synthesis of traditional snowplow and jump turn techniques.
That works well on rough consolidated snow.

I think it's fair to say that he is teaching one to carve on one ski and to step (sometimes with
a bit of a hop) the other ski into position..He turns on one ski and balances the end of the turn on both, and I think it's fine but it's certainly not ALWAYS necessary to ski even light gear like that. He also often combines double-poling with his steps and hops, which I think is just great, and perfectly useful at times, though there are many in certain areas of this wonderful country that forbid such methods.. Obviously what he teaches is not menat to be used for high-speed skiing, but XCD is generally not about that anyways.
The beauty of what he is teaching is that his method would, at least in theory, get a skier down most slopes by far under a very very wide set of conditions using a wide variety of ski gear from very light to heavy ..

I later realized instructors have already thought about it... Just like when I wrote my own time travel theory when I was 8 and realized later it was already discovered by some other funny guys and it was called "relativity"...

Wow. You figured out relativity at 8!

When I took modern physics in college I remember thinking that relativity was the simplest, most non-intuitive concept I've ever heard of. I was usually pretty good at this physics stuff but I recall thinking I'd had a good grasp on it and then having to apply it and getting myself all balled up.

Years later I heard Carl Sagan's explanation of why the speed of light must be constant (or very near to as we humans can tell) and it blew my mind. It was so simply elegant and impossible to refute.

I once got thrown out of class in high school by asking if time travel was possible if one could go faster than light. I didn't know about relativity but my teacher kept insisting that it was impossible to travel faster than it. Then he got fed up and sent me to the principle.

So I guess it isn't impossible to come up with those ideas on your own, although it does seem to be physically impossible to time travel in that way. The hard part seems to be deciding what light is, how it travels though media or lack thereof and realizing that it's speed is constant in all reference frames. Historically that was a very difficult problem... and it's still far being the absolute truth.

Afterall... Einstein never won a Nobel prize for relativity.

[Raventele]

light is a form of energy which , by various methods, can be exchanged and transformed into other forms of energy..And the fact that forms of energy are variously interchangeable is really the most amazing thing in the "physical" universe --which is also just the other side of the coin of reality.

I don't know what you mean by "drag" force on the boots..

That's right. Thanks for your interpretation, MikeK.

The second robot is demonstrating plow turns, not tele

The robot seems to manage tele...a sort of.

That's probably true.
I don't know what the wedge tele turns look like exactly because I've never tried wedge turns on telemark gear in a conscious way.

Right, his techniques seem to be sound and versatile.
But I'm looking for more efficient and easier ways.

I remember when I started, I was trying to put one leg behind, to drop the knee. I tried it, didn't work for me. I tried everything for several weeks. When I finally figured it out by myself, I remember wanting to write a book, with a title that would sum it all: "Telemark, by Johnny: Put one foot in front of the other". (My original french quote is much cooler: "Le Telemark: CRISSER son pied en avant..."

We may be able to learn a lot of things from automobile layout.
Whether we go by FWD or RWD is one of my themes in this thread, and I prefer RWD because of the same reasons described in the case of automobile.

Less experienced skiers would benefit from the wedge tele. The robot is very exaggerated but I'll admit the only way I can turn skinnies is like that. Even if I 'parallel' turn them, I'm still slightly wedged because I am pressure edging and not rolling the skis like the first robot. It takes a lot of technique to carve a double camber ski with minimal sidecut like that. I don't have that.

The dude with the curly hair whom I couldn't understand a word of was showing the same thing. Obviously he was showing how to make a wedge turn with xc gear, which is fairly easy. Then you can kind of try to cheat that by doing a wedge with an inside step which gets you more parallel. Eventually he gets to moving to a telemark stance during his traverse. He still has a bit of a wedge stance during this, which is fine IMO. It may not be as beautiful as a tight, parallel stance but it gets you down the hill. I have no shame in putting some wedge to the skinnies.
