Seahawks, Broncos Gear up for Super ‘Green’ Bowl

Publication: NBC News   Date: January 30, 2014   View Article

Given the legalization of recreational marijuana in Washington and Colorado, this year’s Super Bowl featuring the Seattle Seahawks and Denver Broncos has already earned a few chuckles as the “green” bowl. Pot jokes aside, the annual pigskin revelry has become progressively more environmentally friendly over the past 20 years, according to the National Football League.

“Every year we are trying to push harder to make this a greener event,” Jack Groh, who has directed the league’s environmental program since Super Bowl XXVIII in Atlanta, told NBC News. Whether Super Bowl XLVIII will be the most environmentally friendly yet is hard to say, he noted, but boasted that it will be “the greenest sports event that New York and New Jersey have ever hosted.”

Tiny sensors that measure amplitude are big step

Anyone who watched the recent X-Games coverage heard commentators obsess about “amplitude” — how high snowboarders such as Shaun White soar above the lip of the superpipe to perform aerial tricks.

Scientists more concerned with using vibrating sensors to detect harmful chemicals in the air we breathe and food we eat than White’s frontside double cork 1260 share the love for amplitude.

New Year’s Resolution: Get fit, make electricity

A new generation of workout machines that generate electricity as you work up a sweat are poised to invade fitness centers and help you keep your New Year’s resolution to trim down your waistline.

The electricity generated by the machines is fed back into the grid, helping the gym save on its utility bills.

The why of water bouncing balls

Publication: msnbc.com   Date: October 27, 2011   View Article

Some balls bounce on water, and some do it better than others. The best in class is the trademarked Waboba, which stands for water bouncing ball. And now a team of mechanical engineers has figured out why the Waboba works so well.

The team led by Michael Wright at Brigham Young University’s Splash Lab in Provo, Utah, did this by attempting to skip three types of balls across the water, videotaping the activity, and analyzing the footage. Their results are posted on arXiv.org, including a video that explains it all.

Golfers: How to sink more putts

Publication: msnbc.com   Date: June 13, 2011   View Article

Leave it to a golfing physicist armed with geometry to give all us duffers some simple advice that should make more of our putts fall.

The advice is this: instead of just lining up the putt at hand, take a little extra time and determine the target line for several equidistant putts a few steps to the left and right of the ball.

“What you’ll notice is that those target lines all sort of converge at the same place,” Robert Grober, a physicist at Yale University in New Haven, Conn., told me today. “It is as simple as that.”

To sink the putt, aim for this area.

Why a red shirt helped Tiger Woods

Back in the noughties, Tiger Woods, dressed in a red shirt, hoisted a trophy on the 18th green on almost every Sunday that he started out with at least a share of the lead. Science is helping explain how the red shirt helped him — and why it won’t do much for the golfer now.

“It made him feel more confident and powerful and made others shrink in fear of this alpha male among us,” Andrew Elliot, a professor of psychology at the University of Rochester, told me Tuesday.
