## Tokyo and Fukushima win Olympic prize

Tokyo won out as the “safe option” against Madrid and Istanbul in the competition to host the Olympic games. Also good news Prime Minister Abe gave a promise to clean up the Fukushima plant by 2020.

In Japanese he provided following soundbite:
“We understand that there have been people voicing concerns over the contaminated water issue in Fukushima. What I can say is the government is taking the lead here to completely solve the issue. And to do that we are implementing drastic measures with firm resolve. I will be explaining (to the International Olympic Committee) that in seven years time, in 2020, it will not be a problem at all.”

## How fast Usain Bolt could have run?

Some Physicists (H. K. Eriksen, J. R. Kristiansen, O. Langangen, I. K. Wehus) have calculated how fast Usain Bolt would run, if he did not start to celebrate before the finishing line. The paper is available at http://arxiv.org/abs/0809.0209

By digitising video footage and then fitting a smoothed spline they are able to give estimates of Bolts time assuming, either that his speed at the end would match Thompson, or that he kept his acceleration 0.5 m/s2 after 8 seconds. In these two cases, we find that the new world record would have been 9.61 +/- 0.04 and 9.55 +/- 0.04 seconds, respectively, where the uncertainties denote 95% statistical errors.

Usain Bolt breaking 100m record in Beijing

His coaches prediction of 9.52 is within the error bars, but could be called optimistic based on size of the 95% confidence limits. World record times would be valid with more favorable conditions so it is likely that Bolt can run 100 m faster than 9.5 seconds in the future.
