Science and bicycling meet in a new helmet design

This entry was posted in Science on by .

When we recently did an overview of the evolution of bicycling technology, helmets were barely mentioned. They’ve been made out of the same materials for decades, and the only improvement they’ve seen in that time is a more efficient venting layout. But the timing of that article turned out to be propitious because, a few months later, Trek got in touch to let me know it was introducing the first major change in helmet technology in years.

The obvious answer is that helmets are meant to protect your brain when your head experiences an impact. But the more detailed answer requires delving into a little bit of physics. On a simple level, an impact generates force that, if nothing is protecting you, is translated directly to your skull. A helmet’s job is to dissipate that force. If a helmet could be arbitrarily large or heavy, this would not be a problem. But cyclists are notoriously picky about their equipment’s weight and aerodynamics, which means that a helmet has to do all its redirection of forces in as little space as possible, using light materials.

Free Bike Helmets Offered At Carnegie Science Center

PITTSBURGH (KDKA) ‘ You and your child can get a free bike helmet at the Carnegie Science Center on Sunday.

The program, in partnership with the Brain Injury Association of Pennsylvania, will be held at the Carnegie Science Center on March 31 from 12-3 p.m.

Guests will learn about brain injuries, enjoy hands-on activities and have the opportunity to get fitted for a free bike helmet.

Uber’s IPO Dreams Of Jet-Pack Travel Yet Warns That Bicycling Without Helmets Is Dangerous

‘We ‘ hope to add autonomous vehicles, delivery drones, and vertical takeoff and landing vehicles to our network,’ dreams the company that admits in its IPO that it has yet to shake-off sexual harassment claims.

Also admitting to an accumulated deficit of $7.9 billion, the company adds that ‘we expect our operating expenses to increase significantly in the foreseeable future, and we may not achieve profitability.’
