Einstein and BMX bikes to rebrand physics

Einstein year is being launched today at the Science Museum in London with the first performance of a BMX stunt dubbed the "Einstein flip".

The stunt was created by Cambridge physicist Helen Czerski in collaboration with professional BMX rider Ben Wallace. Ms Czerski claims the stunt is "pushing the boundaries of what it is humanly possible to do on a bike".

Mr Wallace, 18, a competitor in extreme sports events around the world, will launch off a 1.8m (6ft) high ramp and spin backwards through 360 degrees while simultaneously folding his bike underneath him in a move known to BMX devotees as a 'tabletop'.

At one point, onlookers should see him upside down, travelling at 15mph, with his head almost 4m off the floor.

Ms Czerski looked at the physics behind different stunts and used computer simulations to determine the limits of what would be physically possible in the manoeuvre. She drew on several theories for inspiration, including the conservation of angular momentum and Newton's laws of motion.

It is rumoured that Einstein was a keen cyclist who claimed his theory of relativity came to him while he was out riding his bike.

No - a backflip table top. Only done by about 50 other riders already. Flip whips are way crazier - along with flip 360s.

Articles written for the bmx stupid are always so difficult to actually read. The writers always make everything sounds so homosexual. A backflip is not a 360 - a backflip is a backflip... does someone describing gymnastics or diving have to explain a backflip? It's a BACKWARDS FLIP - dehr.

That was pretty confusing.

so howcome, if people are alredy doing those tricks, do we need a scientist computing and simulating? the guy had to just try it in the end anyway. it just seems like an expensive solution to a problem that wasn't there...

spin backwards through 360 degrees


BmxTrix, When I read that I think they mean a backflip 360 table top. If it is a 360 table, thats pretty ridiculous to rename it. I wonder if anyone would ever use the name haha
