History of Sports Memorabilia
The other day I was cataloguing three boxes of baseball cards
for a friend of mine and I began to think about how this entire
card collecting and sports memorabilia phenomenon began. If you
are a closet fan (as I am) of shows on television that...
Indoor Environment and Sports Performance
I saw a horse race once where the winner was not declared until the race people had a chance to look at the “photo finish.” Boy was it close. There was a bout 3 inches difference between first and second place. What could that second place...

The Difference Between Karate and Tae Kwon Do
The two most common martial arts practiced in North America are

The NFL Needs a New Tie-Breaker
After enduring that disgusting final weekend of the NFL season, I have come to the conclusion that a new tie-breaker is needed. How a team performs during the final weekend should be the first tie-breaker, with all the current tie-breakers falling...

Paintball guns go high-tech
SITE Manufacturing (Redding, Calif.) has taken information attained during more than 23 years of fabricating hi-tech carbon composite components, such as telescope housings and applied it to the sport of paintball. "One year around Christmas, we decided we wanted to do something else," said SITE plant manager Dave Weir. " We spent the next three months scheming and developing an all-carbon-fiber composite paintball gun barrel." The product was the ST!FFI, a tournament-quality barrel with a stepped bore (0.002 larger at 5 inches) available in one of a selection of bore sizes in 10-, 12-, 14- or 16-inch (254 mm, 305 mm, 356 mm or 406 mm) lengths or as part of a ST!FFI SW!TCH kit (with nylon carrying case) containing a 0.695-inch bore barrel with four exchangeable sizing breeches (0.685 to 0.691 inch, in 0.002-inch intervals) used to adjust the barrel to minor variations in available paintball ammo.
Barrels were designed with the help of SolidWorks 3-D
design software from SolidWorks Corp. (Concord, Mass.), utilizing woven carbon prepreg permeated with a resistant hi-tech polymer epoxy resin, supplied by Bryte Technologies (Morgan Hill, Calif.) with fiber-to-resin ratio controlled to within ±3 percent resin content. Plies of prepreg are meticulously cut to within ±.005 inch (±0.127 mm) on a programmable computer-controlled cutting table from Eastman Machine (Buffalo, N.Y.), then table-rolled onto a tubular polished metal mandrel (precision ground to within ±.0005 inch) and vacuum bagged. SITE declares that barrels are moulded to a tight ±.0005-inch tolerance on the bore size.
