Augusta 2018

Rajat Mittal, an aerodynamics expert and professor of mechanical engineering at Johns Hopkins University, used Newton’s second law of motion and computational modeling to predict the trajectory of a golf shot in a variety of wind conditions. The results of the study, published in the June 2017 edition of Sports Engineering, the journal of the International Sports Engineering Association, found that the tree canopies (up to 30 meters, about 98 feet, high) around the 12th hole at Augusta National affect the average wind speed along the flight path of the ball.
A series of simulations with eight wind patterns and various wind speeds showed that a headwind at No. 12 created the largest uncertainty in the landing spot of the ball, and that winds from the northwest and southwest could cause a perfectly struck ball to be pushed up to 12 feet off line. The study also revealed that tossing grass to gauge the wind at the tee produced little correlation to the wind at the green, and it debunked another long-held belief.
“At least from a mathematical point of view and from our analysis, there is nothing one can learn from the 11th green that can be applied to the 12th hole,” Mittal said in a telephone interview.
Too much information and overthinking, he concluded, are counterproductive.

Masters Update

What the heck was Justin Rose doing 
on the 1st replay hole looking at his putt?
holding one finger up at the putt?
hindu chant?

i am so happy for SER-GI-O!

mr science explains . . . 

I didn't see it, but the new green-reading technique is called
aimpoint.  The idea is that no matter
where you are around the hole, there is a single point on the green at
which you need to aim the putt (where it would go if it were straight).
So, if that point is a foot north of 12 o├žlock, then from 3:00 or 9:00
you play 1 foot of break, from 3 feet above the hole you hit it 2 feet,
and from 3 feet below the hole you hit it 4 feet.  Finding that point is
complex, but in aimpoint express you guess the slope of the green in
degrees, and if it's 1 degree you hold up 1 finger so that the hole is
on one side of your finger, and you hit the ball at a point on the other
side.  If you think it's 2 degrees, you hold up 2 fingers, etc. On fast
greens you can't have more than about 2 degrees of slope at the pin, or
the ball won't stop.


People illegally shooting near Verrado golf course (Phoenix, AZ)

A group of golfers in Buckeye recently had to take cover — not from flying golf balls, but stray bullets — and police said it’s becoming a common problem.

The Buckeye Police Department has received several calls regarding shooting toward the new Victory at Verrado Golf Course, north of Indian School Road between Verrado Way and Tuthill Road, according to a post on the department’s Facebook page.

During a recent incident, several golfers had to take shelter behind a bathroom to avoid being shot.

Four people found shooting toward the golf course face endangerment and weapon-related charges, and their guns were seized.

Police have received several reports of people shooting in the desert area along Tuthill between Missouri and Maryland avenues into a 20-foot berm facing the golf course, the post states.

Tuthill Road and the fifth hole at the golf course are less than 400 feet apart, and signs are posted in the area stating no trespassing, no shooting and no hunting is allowed.

I read the news today, oh, boy . . . ..
