A 100 TeV question

2 months agoAcademics / Physics : Resonaances

It is practically decided that the next high-energy collider we build is the ILC - an electron-positron linear collider in Japan starting at the center-of-mass energy starting at 250 GeV. But it's already high time to think of the following step. Show More Summary

Uncertain Dots, Episode 6

This week’s episode of Uncertain Dots is, if anything, even more free-form than previous weeks, including a brief cameo from one of Rhett’s kids: Topic covered include the arrangement of faculty offices, the relative lack of demos for E&M (compared to mechanics, where there are endless videos to analyze, etc.) a little bit about science…

Imagine the beam

A former physicist uses accelerator data to create artistic visualizations. Sixteen years after graduating as a nuclear physicist, following a long period of working as a digital designer and educator, Andres Wanner again immersed himself in a physics environment at TRIUMF, Canada’s national laboratory for particle and nuclear physics.

DECam pinpoints asteroid

When weather prevented other telescopes from tracking a potentially hazardous asteroid, the Dark Energy Camera stepped in. For seven minutes earlier this month, two Fermilab physicists moonlighted as astronomers who, like the Men inShow More Summary

Quantum Mechanics, The Theoretical Minimum

In recent years Leonard Susskind has been giving an excellent series of lectures on basic ideas of theoretical physics, under the title The Theoretical Minimum. The general idea seems to be to provide something in between the usual sort of … Continue reading ?

Least Physics-y Physical Activity?

I’m running errands today, so here’s a quick post picking up a question from last week’s Olympic physics hangout: What sport involves the least physics? One of the kids in the classes we were video chatting with asked that, and I really like the question, though it was a struggle to answer. It’s one of…

More Quick Links

First, a couple of examples of recent progress in mathematics Terry Tao has some new ideas about the Navier-Stokes equation. See his blog here, a paper here, and a story by Erica Klarreich at Quanta here. I’ve been hoping to … Continue reading ?

Scientists complete the top quark puzzle

Fermilab's CDF and DZero experiments have discovered the last predicted way to produce the top quark, the heaviest elementary particle. Scientists on the CDF and DZero experiments at Fermi National Accelerator Laboratory have found the final predicted way of creating a top quark, completing a picture of this particle nearly 20 years in the making.

Science Journalism vs. Sports Journalism

Over at Backreaction, Bee takes up the eternal question of scientists vs. journalists in exactly the manner you would expect from a physicist: she makes a graph. Several of them, in fact. It’s generally a good analysis of the situation, namely that scientists and journalists disagree about how to maximize information transfer within the constraints…

Sochi Physics Homework

2 months agoAcademics / Physics : Dot Physics

The 2014 Winter Olympics are finished (in case you didn’t know).  The Olympics are filled with interesting physics problems.  If only I had more time, each of these could have been a nice blog post. Instead, it’s up to you...

Nailing down the Yang-Mills problem

Millennium problems represent a major challenge for physicists and mathematicians. So far, the only one that has been solved was the Poincaré conjecture (now a theorem) by Grisha Perelman. For people working in strong interactions and quantum chromodynamics, the most interesting of such problems is the Yang-Mills mass gap and existence problem. The solutions of […]

Olympic Physics Chat

I spent a while on Friday morning talking about the physics of the Olympics with a couple of science classes in Tennessee and Lawrence Norris from the National Society of Black Physicists, organized by Adam “@2footgiraffe” Taylor. This was done via a Google hangout, so the video is recorded on YouTube: The recording seems to…

What Is the Slowest Running Speed For a Loop-the-Loop?

2 months agoAcademics / Physics : Dot Physics

I’ve looked at the loop-the-loop problem before. The basic idea is to take something (like a car) and drive around a vertical loop while not leaving the track. It’s a cool stunt especially with a human. How does it work?...

Plot for Weekend: dream on

2 months agoAcademics / Physics : Resonaances

To force myself into a more regular blogging lifestyle, I thought it would be good to have a weekly column. So I'm kicking off with the Plot for Weekend series (any resemblance to Tommaso's Plot of the Week is purely coincidental). You understand the idea: it's weekend, people relax, drink, enjoy...

‘Black widow’ pulsars consume their mates

With a deadly embrace, 'spidery' pulsars devour their partners. One such pulsar is the first rapidly spinning black widow to be discovered using only gamma rays. Black widow spiders and their Australian cousins, known as redbacks, are notorious for killing and devouring their partners. Show More Summary

Introduce a Girl to Engineering Day

2 months agoAcademics / Physics : Asymptotia

Apparently it was Introduce a Girl to Engineering Day yesterday, so some might say I missed it. But as you know, I think that every day should be Introduce a Girl to Engineering Day, so it is not too late! Have a look a website for it I found (here). Show More Summary

What Is the Resistance of a PASCO 750 Interface Box?

For the latest in our ongoing series of post where I overthink simple questions, I’d like to present the longest single continuous experiment in Uncertain Principles history, which took six and a half hours yesterday. All to answer the question in the post title. This may seem like a waste, given that I could download…

Godzilla Gets Bigger Each Year

2 months agoAcademics / Physics : Dot Physics

I bet you thought Godzilla was godzilla-sized. Well, you are wrong. Godzilla is BIGGER THAN GODZILLA. Check out the new poster from the next version of Godzilla movie. That’s a big Godzilla. BIG. io9 has an interesting post that includes...

Statistically significant

Michelangelo D’Agostino taps his physics ingenuity daily as a data scientist. Michelangelo D’Agostino took a few forays into the world outside particle physics before confidently switching to a career in data science, where he exercises...Show More Summary

US HEP Theory Funding News

Laurence Yaffe has gathered some information about DOE funding of US HEP theory groups, showing sharp drops (average 23%) in such funding for groups reviewed in FY2013 and FY2014. These drops imply serious reductions in the numbers of theory graduate … Continue reading ?
