After seeing Batman Begins, Rob Gardner tours the parts of Chicago that appear in the movie. "It seems Chicago is more Gotham than New York, which of course is the 'real' Gotham City," Rob writes.

All in the numbers
Debbie Harris watches as the NuMI beam at Fermilab moves from crawling to running. Physicists have increased the number of protons that can hit a graphite target and then transform into neutrinos. "The problem with neutrino experiments is that since neutrinos interact so rarely, you can basically NEVER make too many of them at a time," writes Debbie. "So this means that the experiment wants as many protons as possible."

Gordon Watts attends Fermilab's celebration in honor of its particle accelerator, the Tevatron. The Tevatron has achieved a new milestone for integrated luminosity, which is a measure of the total data it has collected as a function of time. "The more data we get, the more physics we can do," writes Gordon. "Thanks! And congratulations!"

Tommaso Dorigo has found a way to improve some of his experiment's numbers: He has applied his Hyperball algorithm to the problem of measuring the energy of jets, sprays of particles produced when protons and antiprotons collide. "I am very excited by all this," he writes.
