I’m delighted to be back doing numerical relativity research at Caltech after taking a year leave to deploy to the South Pole with the South Pole Telescope collaboration. I will continue to be involved with the South Pole Telescope data analysis in parallel with my work at Caltech to simulate formation pathways for supermassive black […]Read more "Supermassive Excitement"
Since IBM released access to its 5-qubit quantum computer, with accompanying tutorial and ability to simulate and program it easily (via a graphical language that spits out a simple code for archival along with results), I’ve been kind of obsessed. As I worked my way through the tutorials in IBM’s simulator, for my own benefit […]Read more "5-qubit quantum computing simulator"
As you might have heard on my website, my newsletter, my Twitter, or, if we’re colleagues at Caltech, at work, I am currently working on the South Pole Telescope (SPT) onsite at the South Pole in Antarctica for January-November 2016 (I am employed by the University of Chicago). I have taken a sabbatical from my NSF Astronomy […]Read more "When Antarctica Just Isn’t Cold Enough: South Pole Telescope (SPT) Fridge Cycle"
I’m going attempt to give an accessible introduction to general relativity for non-mathematicians without glossing over the mathematical objects one must to get a feel for to be able to follow research in the area. Let me know how successful I am!Read more "Paper, astrolabe, ruler, compass: a short introduction to the math behind general relativity"
featured image credit: M. Kornmesser/European Southern Observatory Sobral et al. in recent work slated for publication in The Astrophysical Journal, claim observation of a galaxy, CR7, likely hosting a large contingent of Population III stars. The New York Times also has good summary; you know it’s important when actual stars get the movie star treatment. While I’m not in a position to […]Read more "Population III stars were fusing hydrogen before it was the hot thing to do"
There is both room for and a need for many different types of physicists and scientists to kick progress up a notch. Some of the most mind-stretching and inspiring are those who are philosophical about their work, as well as those who are interdisciplinary in their understanding. Scott Aaronson fits in both camps and shares […]Read more "book review: Quantum Computing Since Democritus"
June 1, 2015 I was thrilled to start my 3 year tenure as an NSF Astronomy and Astrophysics Postdoctoral Fellow (NSF AAPF) at Caltech. I am therefore declaring June 1 as my official academic New Year. I’m treating this fellowship period as my shot to make a scientific difference, and here’s to the next 3 years. I have an structured routine scheduled, […]Read more "Happy Academic New Year, 2015"
I spent my Fall as an intern in propulsion analysis at SpaceX. I had unparalleled mentors in rocketry, computational physics and software engineering. The intern program is top-notch, and to me represented the most effective “in” to the notoriously selective and demanding company. Moreover, the internship duration was a perfect interlude in my academic career. […]Read more "#OCCUPYMARS: my experience as a SpaceX intern"
Gravitational lensing results from the fact that General Relativity describes our universe: mass bends light and can function in effect like a lens, bending light in ways that can be used to infer the mass distribution itself. Gravitational microlensing is due to this same effect, but refers to the detection of objects which are of […]Read more "Finding earth like planets from the comfort of our own planet"
Here’s a video introduction to the Game of Life Historically, one of the pioneers of computer science John von Neumann was interested in finding machines which could reproduce themselves. He developed an abstraction allowing him to mathematically model his work on a computational grid. A mathematician John Conway took up and simplified his work publishing […]Read more "The Game of Life-simple rules, complex behavior"
