    False! What can you do with a long stroke that can't be done with a short stroke that affects the ball?
    The ball doesn't care what happened before or after contact.

    I would bet that speed glued...
  2. Yes I do. If you want me to take you seriously...

    Yes I do. If you want me to take you seriously you will provide examples.
    I know how to optimize trajectory of balls and understand the physics perfectly.
    I shake my head when I see equipment...

    So it is OK to show off as long as it is about TT. OK.
    The most significant thing is that I can tell the difference between BS and fact.
    BTW, if you get to retirement and haven't done anything...
  4. I am pnachtwey or Peter Nachtwey, the engineer/entrepaneur

    I started play TT just before freshman year in high school. I broke my right wrist so I couldn't play high school football for a few weeks. I played left handed through my sophomore year in college....

    I am not confused. :)
    The pros are excellent athletes but they are not engineers. Engineers think in terms of isolating problems and optimizing them. The OP has question about spin and serves. ...

    Think of a 2mm sponge as having 4 layers of 0.5mm sponge glued together and a 1.5mm sponge having 3 0.5mm layers. if a 10 N force is applied to the sponge each layer will be compressed by the same...

    Does anybody else hazard a guess, opinion or better yet, a scientific argument.


    Another opinion, why?


    This fine but the thread is about harder rubbers having less spin. You might like...

    But you can use common sense.
    There is a point where the rubber is too hard. At some point making the rubber harder will reduce spin. At some point making the rubber softer will reduce spin. In...

    That assumes the ball impacts with enough force so the rubber and ball grip.
    Like you said, it gets complicated. There isn't much surface area in contact between the ball and rubber at first. ...

    Think about it. If there was only friction then the ball's rotation would be proportional to the tangential speed of the paddle. However, spinny rubbers will deform or stretch across the surface...

    What do you mean you don't have much strength? Wimp.
    15 year old girls can pitch soft balls at pretty good speeds. Their arm speed is more than enough to loop all but the most severe back spins. ...

    Chopping is difficult with most inverted rubbers. Most are too bouncy.
    What are you trying to chop with? You don't want rubbers or pips that are too bouncy or have too much grip.

    There are frauds in golf too!?.


    Just because you push off on a pressure pad doesn't mean you weigh more. Your mass didn't increase.

    I am thinking about it. I am older and don't move like I did when I majored in TT in college. Not really but I played more TT than studying or spent time in classes.

    Nonsense!, unless is was a coal miner or oil driller.
    Power/energy comes from the player. How much weight is transferred is not as important as how fast it is moved.

    You mean Hexer has a higher tangential COR and less normal COR.

    I use both. Top spin is necessary for making an aggressive shot when the ball is low. Spin is not so necessary when the ball is higher. After making a loop, hopefully the opponent will return the...

    So what it different? A ball has velocity and spin around an axis. The ball doesn't care how it is achieved.
