I gave a short introduction to how to give a presentation today to the students who will be presenting their research in our twice-weekly Summer Student Seminar Series. This included examples of a data slide that is bad in the ways that students’ first attempts at data slides tend to be bad, and the same… Continue reading Bad and Good Presentation Graphs

Big News in Tiny Physics
A couple of significant news items from the world of particle physics: There was a conference on neutrino physics recently, and the big news from there is that two experiments measure something funny with neutrino oscillations, namely that the oscillations seem to proceed at different rates for neutrinos and antineutrinos. This is a really surprising… Continue reading Big News in Tiny Physics
Photons: Still Bosons
Last week, Dmitry Budker’s group at Berkeley published a paper in Physical Review Letters (also free on the arxiv) with the somewhat drab title “Spectroscopic Test of Bose-Einsten Statistics for Photons.” Honestly, I probably wouldn’t’ve noticed it, even though this is the sort of precision AMO test of physics that I love, had it not… Continue reading Photons: Still Bosons
Crowd-Sourcing Physics Questions
There is a proposal for a Physics Q&A site along the lines of Stack Overflow for computer stuff. Like many such projects, this largely conflates “physics” and “theoretical particle physics,” so I’m not sure how much of a contribution I can really make. I’ve got plenty of theorist readers, though, so if this seems like… Continue reading Crowd-Sourcing Physics Questions
Insults Are Easy, Community Is Hard
Josh Rosenau makes an excellent and important point regarding prayer meetings and the Gulf oil spill: that the point is not so much that God will stop the oil gushing into the Gulf, but that religious groups are a key community organization point for getting people together to work on the problem. He puts this… Continue reading Insults Are Easy, Community Is Hard
Scientific Salary Stratigraphy: Past Performance Does Not Guarantee Future Results
Inside Higher Ed has a news squib about gender disparities in academic science, which points to a Nature story about a survey on job satisfaction (bad IHE, giving a false impression on the story!). The gender portion of the story is limited to a short section at the end of the article, and one graph:… Continue reading Scientific Salary Stratigraphy: Past Performance Does Not Guarantee Future Results
Uncomfortable Question: My Bad?
Next in line of questions from readers, we have tbell with: Since science is a self-correcting process (maybe only at a statistical level, not necessarily an individual level), it would be cool if you would relate the last time you were seriously wrong about some aspect of science or research, and how you altered your… Continue reading Uncomfortable Question: My Bad?
Relatively Comfortable Question: Physics First?
Starting at the beginning of the uncomfortable questions left by readers, we have Tex asking: If physics is the basic science that underlies almost every other science, why do American high schools usually teach it in the 3rd or 4th year, after biology and chemistry? Shouldn’t it be the other way around? Physics first, then… Continue reading Relatively Comfortable Question: Physics First?
The Physics of the Imbecile: Chopra Interviews Kaku
I don’t remember who pointed me at this transcript of Deepak Chopra interviewing Michio Kaku, but if I remember who it was, I fully intend to hate them. DC: Is our conversation affecting something in another galaxy right now? MK: In principle. What we’re talking about right is affecting another galaxy far, far beyond the… Continue reading The Physics of the Imbecile: Chopra Interviews Kaku
Dropping Bose Condensates for Fun and Science
An experiment in Germany has generated a good deal of publicity by dropping their Bose-Einstein Cendensate (BEC) apparatus from a 146 meter tower. This wasn’t an act of frustration by an enraged graduate student (anybody who has worked with BEC has probably fantasized about throwing at least part of their apparatus down a deep hole),… Continue reading Dropping Bose Condensates for Fun and Science
