I agree with the conclusion (the title of the thread). We've all seen people play TT and achieve some spin with clipboards and other random objects.Whatever physics I learned in my life I have mostly forgotten so I can not take sides here.
I know though that it is in some OPs interest to keep a thread going for as long as possible
and disputing every solid argument helps here.
I notice though that like many many threads this one also takes on a life of its own . If we would have stuck to the title of the thread ""Don't blame the rubber if you don't get enough spin. It's your fault.""" AND if we would leave out all the (for me) math and physics BS, I hate to say it
but BB is right. Regardless of what rubber we have , we are responsible to make the spin.
If we feel we can not make enough spin we can try every rubber on the market but in
the end we still have to create the spin.
Sorry ! 😂
What I don't understand how brokenball's formula actually gets us to the conclusion. He seems to be arguing that any object made of any material (let's say, that stainless steel blade covered in oil) will achieve an exact amount of spin based on contact point and racket speed alone. This seems like a bizarre hill to die on, and I just find it odd that he would rather spend his time calling people stupid for not understanding it, but won't answer simple questions that are intended to give him a chance to explain more in depth.
This is a topic that's actually pretty interesting to me, so I was hoping for a good discussion with a self-proclaimed high level physicist and engineer to learn something new. Instead, I feel like I got a lesson in antisocial psychopathy.
