love the video, love the music. Dan never disappoints! Can't wait for next year's top 10!

Thank you for this. I wasn't taking into ALL frictional forces. After izra's comment about soft contact, and that JSH's pips rubber may work more along the ways i have been describing, I realized i wan't factoring in rolling friction. I was only assuming kinetic friction (which would be...

I hate to hijack this post but I am enjoying this discussion. My comment is about the spin, not the direction of where the ball heads after contact. There are two separate velocities at play, linear velocity and angular velocity, I am merely focusing on the latter. Without getting into too much...

That isn't how it works. Just because the contact velocity appears relatively lower than if the ball was spinning the other way doesn't make a difference. The ball was already spinning in the same direction, and you amplified it. The math behind it - the angular acceleration vector resulting...

Force is proportional to acceleration, and according to the impulse/momentum principle the first isnt a myth. Having written a 3d rigid body simulator, i know enough about angular collision and response to assure you the second is also not incorrect. What other facts have you been told that you...

I dont use protective sheets on my tacky rubbers. I do use water and sponge to clean them and put them back in the case. In my experience, letting the rubbers air dry in a somewhat airtight case in a dark, damp area (such as leaving your case in a gym bag inside a gym locker) revives the rubber...

Water and sponge definitely will restore nearly 100% of the tack. However, you have to be somewhat liberal with the water and use the sponge as a squeegee (using the blue side of the rubber care sponge that comes with the butterfly rubber soap). Once the rubber air dries, you will find it will...

At first, I thought LL Bear was Algerian and named Al Albeari :P This is the most fundamental principal behind every sport, be they martial arts, cricket, baseball, basketball, golf, swimming, even rock climbing... the key to maximizing speed, power and control is to leverage weight transfer...

This most definitely has my vote for top. The collective "whoa" before the applause breaks clearly shows how impressive this shot was!

street pong! no blood no foul!

Omg im laughing so hard at these. I lost it at the shibaev one

I know ZJK was fined for his display of unsportsmanlike behavior, but have you seen his legs? i suspect he didn't kick those add board nearly that hard, rather they crumbled to pieces under the sheer pressure of his overwhelming leg strength.

I find this angle a lot more enjoyable and discernible than what you typically find (behind the table, far away but zoomed in so the perspective on the table is completely absent). This way you can adequately gage the spin, speed and the positioning of the players vs. the traditional view. Thank...

Hi Mr. R, I am extremely curious about the national TG3 blue sponge tuned. How does it compare to a domestic tg3 neo 39° (factory tuned)? Is it harder or softer, springier or deader? How strong is the difference and what/where do u notice it? I should add that (ive been told that) im around a...

As far as rubbers go, here is my process: Megaspin does a good job of catagorizing rubbers (allround, high spin, high speed, etc). If you google "yinhe rubbers", "729 rubbers", "joola rubbers" or the like, the first link in the result will take you to megaspin's page. Select and look at user...

I came across these some time ago on youtube! You were testing your students on reading spins, I believe?

We aren't as tall as you think..xu xin is 6 feet too

I know the focus 3 snipe has a whitish sponge (made it harder for me to glue because I couldnt tell when the glue dried :-P ) I'm sure other ritc rubbers have similar color sponges. As sebas pointed out, it could be one of the tacked ones
