We did a lab yesterday that asked students to measure the speed of a ball leaving a spring-loaded launcher in a few different ways. this is a great way to talk about the difference between systematic and random errors and how those are dealt with. As a way of starting that discussion, I asked the […]

The victim is us. We lose something else: the experiential side, the joy of photography as an activity. And trying to fight this […]
Photons and Atoms Approaching Equilibrium
The latest snowstorm is wreaking some havoc on my plans for the day, which means I’m going to lift another question and answer from the Physics Stack Exchange, with some modification. This one is a question about thermal radiation: What are the quantum mechanisms behind the emission and absorption of thermal radiation at and below […]

What Counts As Successful Outreach?

Physics Announcements: New Forum, Undergraduate Research Session
I was at a meeting of the Committee on Informing the Public of the American Physical Society at the tail end of last week, so it seems appropriate to post a couple of APS-related announcements here on my return: 1) The APS has just created a Forum on Outreach and Engaging the Public. You may […]
The Internet Makes Everything Better
For one obvious example, I’m typing this on a plane– Southwest has started doing wi-fi on some flights, and it is totally worth $5 to be able to web-surf in flight.It would be even better if the flight wren’t packed, so I could type more comfortably, but I’m ok with just reading (once I post […]

Massive by Ian Sample
The physics book generating the most bloggy buzz in the latter part of 2010 would have to be Ian Sample’s Massive: The Missing Particle that Sparked the Greatest Hunt in Science, about the as yet undetected particle known as the Higgs boson. Detecting the Hiigs is the most immediate goal of the Large Hadron Collider, […]
