I'm Gary O'Reilly and I'm Chuck Knace. And this is playing with science.

Yesterday is a cosmic queries tennis show where we open the floor to our star talk playing

with science family and let them pose the question. So if you ever wondered why your ball

spin and why you must always keep them fuzzy.

I know you like that. Come on now you know I can't I'm just gonna go with it. I'm not gonna

do it. I'm just gonna continue and if you have any interest in a new spin on a never-ending

string theory you are in the right place because our good friend professor Eric God from

Linsburg College, Virginia and author of Gold Medal Physics is the man to unlock the answers

to your questions. Now let's get back to some fuzzy balls that spin. So Eric good to

have you back. Have you been sir? I'm doing great. It's good to be back. How are you Gary

and Chuck? We are fabulous. Yes. So what have you been up to? Well our classes begin

in a week so I've got about three more days before I need to start preparing for them.

It's good to see that those kids are getting a quality education as you last minute their

curriculum professor. Well got all the research done before the class has started.

Oh yeah. Hey by the way now that the Tour de France is over for those who know that you

are the person who does the modeling how did you end up ultimately? Oh we did a really

fabulous job this year. Our last stage we missed by just 11 seconds so we had a fantastic

prediction set. 15 of our stages we did better than 4% 11 of them we did better than 2%.

Wow. So we had good predictions this year. And you now at Chris Froome from the start anyway.

We had yeah I mean I kind of figured Chris Froome was going to be the guy to beat and no one

could beat him so he got it fourth. Can't touch this. All right.

Wait before we go any further so how many does that make for Chris Froome? Three in four.
