The Amplituhedron and Twistors
Yesterday Nima Arkani-Hamed was here at Columbia, giving a theory seminar on the topic of the Amplituhedron, which is a characterization of the integration region in a calculation of scattering amplitudes by integrating over regions in the so-called positive Grassmannian. … Continue reading

Topcites 2013
The people at SLAC for a long time have been compiling “Topcites” data which includes various lists of the most heavily-cited papers in HEP. From 1997-2003 Mike Peskin each year would write something about the significance of the lists. I … Continue reading

Not Giving Up
One question I’ve been wondering about for the last 20 years or so has been what SUSY proponents would do when the LHC finally gathered data and found no SUSY. Would they finally admit this was an idea that hadn’t … Continue reading

Trust the math? An Update
Back in September, I wrote here about the news that Snowden’s revelations that confirmed suspicions that back in 2005-6 NSA mathematicians had compromised an NIST standard for elliptic-curve cryptography. The new standard was promoted as an improvement using sophisticated mathematical … Continue reading
