Freezing my nose off at the bottom of the world. February 23, 2017. After looking carefully at the telescope movements and the detector temperatures, we concluded that the telescope was accelerating much faster than it should have. Unfortunately, the maximum acceleration is a hard parameter to control. It’s set in hardware, deep in the heart of the telescope. So, we had no choice but to open up the telescope’s heart, and change the hardware. The telescope drive cabinet. The circuit board in question.

Technical Consulting; Antique Scientific Instruments; Sundials. The technical world is abuzz with the plethora of large scale telescopes coming over the horizon in the wake of the Hubble Space Telescope’s success (once the right unit system was in use). The Giant Magellan Telescope ( GMT. Is scheduled to be fully up and working in Chile’s Atacama Desert by 2024 and will be the world’s largest optical telescope. The even larger proposed $1.4bn optical Thirty Metre Telescope ( TMT. Australia used in the se...

Biden, is 450 km across, about half the size of Sedna. If it is made mostly of ice, then its gravity probably pulls it into a spherical shape, making it a dwarf planet. How can I be happy?

Visualizing information geometry with multidimensional scaling. This weekend's project was a fun one! Update: Since the original post I made some more progress. I'm developing the code into my GitHub play/manifoldLearning. Repository. Below is from the README. I'm working on a paper about Informtion Geometry. The first step was an iPython notebook . Bicep2 and Software Carpentry. This week NYU hosted a Software Carpentry Bootcamp. Announcement from the BICEP2. Collaboration about the . 2014 Kyle Cranmer ...

Testing interactive blog post. Recently I've been learning more about docker and all the things it can do for us. My student Lukas Heinrich has been working on the Recast. Project and using docker heavily. In parallel, Tim Head. And I have been talking a lot about projects like binder. Decomposing Classification For Mixture Models. So I recently learned. I'm pretty excited about the idea of using IPython notebooks as a . Hotelling's Experiment ¶. This weekend's project was a fun one! Along with Berkeley ...

For the background. However, there are some things I glossed over that are important for understanding the results from BICEP2. The big one is CMB polarization. We’ve known since 2002. To explain some of the mysteries presented by the CMB, cosmologists in the 90s proposed a theory called inflation. SPT has been heavi...
