First measurement of D meson anisotropic flow at the LHC

http://arxiv.org/pdf/1305.2707.pdf

Quarks and gluons flow outward relativistically in the exploding fireball produced in Pb+Pb collisions at the #LHC . Measuring the anisotropic pattern of emission of D mesons (and other particles) tells us about the hydrodynamics of the produced Quark Gluon Plasma (QGP). The QGP behaves as a strongly interacting fluid, flowing at almost the speed of light as a nearly ideal liquid (extremely low viscosity divided by entropy). Using D mesons, we can see that c quarks produced in the collision (not present beforehand) interact enough with the produced medium to be swept along with the flow.

My Adventure Teaching with Glass

As a Glass Explorer, my goal is to transform the way I teach science, making every moment a teachable moment. With the help of +CERN and +Project Glass, I've begun pursuing my goal in the most spectacular way - teaching a class of physics students from halfway around the world while touring the Large Hadron Collider. I'm so excited to share this incredible adventure with you.

Super Science Circle - April 2013 Edition

It's time for another sharing of my Super Science Circle. This is a collection of 400+ active people on Google+ who often post about science. If anyone tells you G+ is a ghost town (not that anyone does any more), get them to import this circle. 

PLEASE SHARE THIS CIRCLE... FOR SCIENCE!

I have personally reviewed each and every person on this list, to make sure that they:

1. Are active and engaged on Google+
2. Regularly post science-related stories on Google+

In this list you'll find scientists, journalists, researchers, professors, astronauts and general science enthusiasts. 

Not everyone in this list is going to be to your personal liking. So what you'll want to do is import the list into a temporary circle. Then move people over one by one into more permanentl... more »

How many ways are there to cover a room using tatami mats?

A tatami is a type of rectangular mat, used as a traditional floor covering in Japan.  There are two types of mat: full mats, whose side lengths are in the ratio 2:1, and half mats, which are square and have area equal to half the area of a full mat.  These mats are typically used to cover rooms whose side lengths are integer multiples of the side length of a half mat. What complicates matters is that historically, it was considered bad luck to have an arrangement of mats in which four mat corners meet at a point.  This means that one would like to cover a room in an "auspicious" way, so that corner of each mat is either at the corner of the room, or touches other mats in a T-shaped junction.

A moment's thought shows that it is impossible to cover a large room in an auspicious way if one uses tooma... more »

Smoke Particles & Shadows

As a demonstration of a fast, real-time physics calculation, here is one of my first exercises using the NVIDIA CUDA Toolkit, with the SmokeParticles sample code compiled and rendered on my laptop. The photo-realistic simulation relies on the 384 processor cores of my laptop's GeFORCE GT 650M GPU to perform the calculations in parallel. Notice the deep shadows resulting from the self-shadowing of tens of thousands of smoke particles tracked for specified point of view and light source (full-screen, 720p).

The Return of the Super Science Circle

Okay, I'll admit, I made a mistake in retiring the Super Science Circle. I wasn't wrong; Communities are still the future and the best way to make friends here on Google+. But I realized that the Super Science Circle is simple and efficient way to get new people to see that Google+ isn't a ghost town.

PLEASE SHARE THIS POST... FOR SCIENCE!

When I was attending +ScienceOnline 2013, I must have helped dozens of people join Google+, and the first thing I had them do was import this circle. It's an invaluable tool for getting new people up to speed.

So, I just did a complete refresh on the circle. I examined every single member and judged them according to my two-part criteria:

1. Active in the last 30 days or so.
2. Regularly post on scientific topics.

SUL now includes Education, Science & Nature, and How-To & DIY

We have discussed more categories being included and this could mean that they are listening. It does have a sense of matching categories more towards the new communities feature moving forward. 

Science & Nature only has 1 entry which is +Periodic Table of Videos. We suspect +NASA +Ron Garan +Fraser Cain +Ray Sanders might be included in addition since this change is brand new. 

Education features mostly universities while How-To & DIY feature many that had previously been in the category Lifestyle (which is still existing).

Any thoughts on these changes and suggestions for the new SUL categories?

Taking a photo of the Sun with a standard camera will provide a familiar image: a yellowish, featureless disk, perhaps colored a bit more red when near the horizon since the light must travel through more of Earth's atmosphere and consequently loses blue wavelengths before getting to the camera's lens. The Sun, in fact, emits light in all colors, but since yellow is the brightest wavelength from the Sun, that is the color we see with our naked eye -- which the camera represents, since one should never look directly at the sun. When all the visible colors are summed together, scientists call this “white light.”

Specialized instruments, either in ground-based or space-based telescopes, however, can observe light far beyond the ranges visible to the naked eye. Different wavelengths convey information about different components of the Sun's surface and atmosphere, so scientists usethe... more »
