    Gases compress and will return almost all the energy used to compress them. Liquids compress but very very slightly.
    You fill footballs, basket balls, and soccer balls with air. You fill your...

    I lent one of my paddles, with H3 NEO on it, to a friend so he could play because he forgot his paddle. I could see from the side that the cheap H3 Neo could generate a lot of spin. I could see...

    I found Vega Pro to be close to Rakza 7. Maybe a little slower. ( opinion ). If Rakza 7 didn't exist I could be happy with Vega Pro. I haven't played with G-1 yet.

    I like my FH rubbers to have a high spin to speed ratio.
    I believe opinions don't count so here is a video to show you, You can decide for yourself.
    I am playing with Rakza 7 soft max on the FH on...

  5. [quote="UpSideDownCarl;352625"]Peter, why do you...

    I agree.


    Many are high school or college age. Few are educated in physics or engineering. They listen to the same garbage that gets repeated over and over again. That is why.
  6. Your argument doesn't hold. It is one sided. ...

    Your argument doesn't hold. It is one sided. 10 cm may be better than 5 cm but is 100 cm? 100cm is definitely a longer "stroke" than 10cm and I am pretty sure that most dart players don't have a...

    So a short stroke is not a stroke? That doesn't make sense.
    You still have explained why a short stroke will not do.
    You haven't refuted my point that what comes before and after contact doesn't...

    I would not distract this topic with talking about dwell time. Dwell time should be its own thread because it will be hotly debated.
    It always has been and always will be until someone, besides me,...

    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...

    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.

    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...
  12. 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?

    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.

    Power/energy comes from the player. How much weight is transferred is not as important as how fast it is moved.
