Myth or real - Stroke smoothness as a requisite for certain shots

The OP wanted confirmation on the following: "My understanding is that for the CB's reaction after hitting it with the cue, all that matters is what the cue is doing at the moment of contact, within a few milliseconds(?) of the impact.... Does anyone here know any science behind this, does the timing/smoothness/delivery etc. whatever you want to call it really affect the range of possible shots that can be executed?"

The answer is no.

No matter how the tip lands on the cue ball, if it generates the same vector as from any other type of smoothness/stroke/timing/delivery, the result of the cue ball will be the same.

Your personal stroke mechanics may end up delivering the tip in a different location with different power and angle. In that case , the vector will be different. But it is the vector difference that makes the cue ball do something different, not an additional parameter affecting the cue ball at the time of contact.

Yeah I know. But the genre is still people insisting ya gotta do this and that etc... they are not entirely wrong.

Player has to set this vector in motion. Many have crooked albeit compensated strokes. The nano histrionics may be the only way they can produce the required hit. Ultimately somebody has to _make_ the shot.

It is a false belief.

According to Newtonian physics, the only thing that causes a cue ball to not be at rest anymore is the impulse vector applied to the face of the cue ball, which has been measured and observed many times with high speed cameras to last less than 1ms. Math agrees. The human body can not generate forces within this short period of time, period.

This means that the impulse vector is the ONLY variable you have to work with. A three dimensional vector is an arrow in space and has the following components:
Position of the Head of the arrow (location)
Length of the tail (magnitude)
Angle of the tail (pitch/yaw)

Therefore the motion of the cue ball is completely determined by:
Tip contact point location on face of the ball the instant the cue tip arrives
The angle of this force
The magnitude of this force.
These can’t be changed during contact.

Fluid mechanics of the air affects things slightly, but it so small it is negligible.
General relativity affects things slightly, but it is so small it is negligible.
Quantum mechanics affects things slightly, but it is so small it is negligible.
The hemisphere that you were born in affects things slightly, but it is so small it is negligible.

You get the idea.

The delivery of the tip to a location on the face of the cueball is not part of this discussion. Its importance in application is isolated from the conversation, because observations of phenomena in isolation from application is exactly what science is.

There is a tendency of uneducated people to be desperate to know something that everybody else doesn’t. They have no credentials to reject an established theory of science based on experience, because their experience is not controlled.

Also, many in the pool player demographic / specific political circles, refuse to allow others to be smarter than themselves. It is called spiteful ignorance. Beware of this.

My credentials: masters degree in electrical engineering, physics focus, and over 10 years of focused pool ball mechanics research.

You just got my original (meaner) post before I edited it :p

HA! I think when I read it and hit the reply button, it was only asking if the match was on and if anyone had a link. Now I come back to post that Anthony won 30-20, and that HE should be on the next Mosconi Cup! hahaha.

He shoots slow though, would be tough to handle the clock.

Hello,
I heard the podcast with Mike telling the league would start in January.
I can not find any new information. Does someone know if this league really started?

I think the best way for you to find out what's happening with the league is to contact the location nearest you. I think the phone numbers for the league rooms are listed on the website. Is there a room close to you that offers the league?

Edit: I called the room nearest to me and it seems that play has started. This Sunday will be the second or third week.
