Since that very memorable day at the Beijing 2008 Olympics, a big question on every sports commentator’s mind has been “What would the 100 meter dash world record have been, had Usain Bolt not celebrated at the end of his race?” Glen Mills, Bolt’s coach suggested at a recent press conference that the time could have been 9.52 seconds or better. We revisit this question by measuring Bolt’s position as a function of time using footage of the run, and then extrapolate into the last two seconds…

The physical sciences are usually taken to be very earnest pursuits by those who work in them. However, most professional physicists and astronomers would also happily agree with the t-shirt mantra
Rules of nature’s Formula Run: Muscle mechanics during late stance is the key to explaining maximum running speed
TLDR
A generic biomechanical model is proposed to investigate the allometry of the maximum speed of legged running and suggests considering the overall speed maximum to indicate muscle inertia being functionally significant in animal locomotion.
Kinematic and Kinetic Comparisons of Elite and Well-Trained Sprinters During Sprint Start
TLDR
The main results showed that at each time XCM and VCM were significantly greater in elite sprinters than well-trained sprinters and the muscular strength and arm coordination appear to characterize the efficiency of the sprint start.
Pranks and Astronomical Antics
Some scientists take themselves and their work very seriously. However, there are plenty of cases of humour being combined with science. Here I review some examples from the broad fields of physics
