Another 100 metres
High-speed running will sap the energy of even the top athletes, but it seems scientists never tire of it. Dutch statisticians have declared the 100-metre sprint could potentially be run in just 9.51 seconds. The current record, set by Usain Bolt in 2008, stands at 9.69 seconds.
If this sounds familiar, its because I wrote not one but two blog posts last year on the very same subject. This time, the researchers used a branch of statistics called extreme-value theory to analyse previous records.
As the name suggests, extreme-value theory is used to answer questions about extreme events. It’s normally used by insurers to calculate the risks of natural disasters, but it seems that a record-breaking sprint can also be classed as “extreme”.
Machines are better than you
Japanese engineers have built a robot that can move faster than the human eye can see. Watch, with the aid of slow mo, how the robotic hand deftly controls balls and sticks as no human can:
LHC will run on half power
Ah, the Large Hadron Collider. It’s been good to Just A Theory, providing a wealth of blogging material from raps to rants, but has faired less well in actually working. Even the classic technological fix, “have you switched it off and on again?” hasn’t worked, because when the LHC boots up again this November, it will only operate at 3.5 TeV, half normal operating power.
The massive ring had to be shut down in September last year after damage caused by an incident that caused the temperature to rise rapidly. The LHD will run through Christmas to let researchers gain experience in running it, and then the power will be boosted to 5 TeV. If all goes to plan, the machine will be shut down again at the end of 2010 to prepare for full power operations of 7 TeV.
