In honor of Super Bowl LV and the Tampa Bay Buccaneers’ win over the Kansas City Chiefs (and former New England Patriots quarterback Tom Brady’s 7th Super Bowl ring as the QB for the Bucs), I thought it would make for an interesting post about how that magic 1st and 10 yellow line is created on our TV screens every February at “The Big Game!” And, during every game in the NFL among other sports broadcasts. The names of: James R. Gloudemans, Richard H. Cavallaro, Jerry N. Gepner, Stanley K. Honey, Walter Hsiao, Terance J. O’Brien, and Marvin S. White are the Men Behind the Yellow Line. That is, the yellow First Down Line you see on NFL broadcasts! What started out as project for Fox Sports to aid viewers watching NHL games over the airwaves blossomed into a new company called Sportvision, Inc. And in 1998 they debuted the First and 10 Line on ESPN. Using a combination of field cameras, 3D models of the field, powerful computers and algorithms, and the field itself as a kind of green screen, they are able to draw the line in virtual real‐time as the players move up and down the field; as well as, simultaneously remove parts of the line to make it appear that it is literally underneath the players. It’s truly digital magic! It was a such a huge success that Sportvision won an Emmy for its technology. “Winning our 10th Emmy Award is a great honor, and truly validates the impact our technology has had in the growth and popularity of a wide spectrum of sports. We are thrilled to share this Emmy with the America’s Cup Event Authority, who has been a wonderful and inspired partner throughout this effort.” Mike Jakob, President, Sportvision, Inc., 2012 They then...
In honor of NFL Super Bowl LIV this past Sunday, here’s a football physics question to tease your brain! In U.S. football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 3.048 meters above the ground, and the ball is kicked from ground level, 10.9728 meters horizontally from the bar. If the ball is kicked at 37 degrees above the horizontal, what must its initial speed be if it is to just clear the bar? Express your answer in meters per second (m/s). The answer can be found here!
