Physics and Physicists: On the Role of the Michelson-Morley Experiment: Einstein in Chicago
"The conventional thought, based on many accounts given by Einstein in his later years, is that he can't quite remember if he was aware of it, and thus, it didn't play any influential role in his formulation of the principles of relativity. This new paper, in press, reveals a slightly different version of what plausible could have happened, based on two accounts : a translation of Einstein's speech he gave in Kyoto in 1922, and a series of speeches he gave in Chicago a year earlier, and especially at…
drorzel | August 12, 2009ZapperZ links to an interview with David Saltzberg about careers for students with an undergraduate degree in physics. As is often the case, ZapperZ proclaims himself "disappointed" with things that I think are about right. In particular, he writes:
[W]hen asked on why one should major in physics, is the best that can be answered is that "... you really like it.. "? What happened to the fact that the skills one acquire majoring in it can be quite useful in one's career, be it in science or outside of science?
Actually, I think that really is the best reason for majoring in physics. Or any…
emjohnson | August 5, 2009Japanese artists' depiction of the horrors at Hiroshima.Hiroshima Peace Memorial Museum
On August 6, 1945 the United States dropped "Little Boy," the first of only two nuclear bombs ever used in warfare, on the Japanese civilians at Hiroshima. In an instant flash of light an estimated 140,000 people were either incinerated or suffered an agonizing death that lasted several days. The standard mythology is that President Truman dropped the bombs at Hiroshima and Nagasaki (three days later on August 9) in order to avoid having to send half a million American soliders to their deaths in a…
oracknows | August 5, 2009Did you know that acupuncture is very much related to astrology?
No, it's not just because both of woo. Rather, it's likely true that the whole concept of "meridians," those invisible "channels" through which our life energy (a.k.a. qi) allegedly flow were indirectly based on astrological signs, which had been used to guide points used by ancient healers for bloodletting. Indeed, far from being "ancient wisdom," by the middle of the second century, needling had been mostly abandoned and even banned by the Imperial Medical Academy in China and prohibited in Japan, only to be resurrected by…

CHART ATTACK!: 8/1/92 | Popdose
"I just read the following in their Wikipedia entry: "In 2009, Boyz II Men announced plans for a new cover album, that covers 'artists I don't think people would expect us to cover!' according to Shawn Stockman." Can Popdose get in on this? Can we make a list of songs for Boyz II Men to cover? Because I want to start with "Detachable Penis" and just go downhill from there."

Guided By Voices | Music | A.V. Club
"Dozens of people can say they were members of indie-rock institution Guided By Voices during its 21-year run, but the Dayton, Ohio-based band was chiefly a creative outlet for a music-obsessed former schoolteacher named Robert Pollard. And Pollard was very creative, capable of writing an album's worth of songs in a single day, and recording and releasing them almost as quickly. "

rallain | July 30, 2009The fall semester is coming up soon. Some students will be taking physics in college. So, here are some pre-class tips - mainly aimed at college students taking algebra-based physics.
Are you afraid?
If you are reading this, maybe you found it because you were looking for stuff on physics. Maybe you are a little scared. You have heard physics is a tough course. Well, that is only kind of true. First, the fear thing. Use it to your advantage. Let fear be a motivator to help you keep up with the class. I think that is the biggest mistake students make. They think of intro physics as…
drorzel | July 29, 2009The Corporate Masters have launched a "featured blogger" program, asking individual ScienceBloggers to comment on news articles from the main site, and publishing the responses with the magazine piece. I just did one on new quantum experiments, which was posted today.
The news article is Supersizing Quantum Behavior by Veronique Greenwood. My piece is Reconciling an Ordinary World, which starts out:
One of the most vexing things about studying quantum mechanics is how maddeningly classical the world is. Quantum physics features all sorts of marvelous things--particles behaving like waves,…
drorzel | July 29, 2009So, yesterday featured a silly poll about underappreciated old-timey physicists. Who are these people, and why should you know about them?
Taking them in reverse order of the voting:
Rudolf Clausius is the originator of the infamous Second Law of Thermodynamics, which states that the entropy of any closed system will tend to increase. He was one of the most important figures in terms of systematizing the study of thermodynamics, pulling a lot of other people's work together, and showing how it all fit.
James Joule was a brewer as well as a physicist, making him a really good guy to know. He's…
oracknows | July 27, 2009Last week, I expressed my surprise and dismay that the Atheist Alliance International chose Bill Maher for the Richard Dawkins Award. I was dismayed because Maher has championed pseudoscience, including dangerous antivaccine nonsense, germ theory denialism complete with repeating myths about Louis Pasteur supposedly recanting on his deathbed, a href="http://oracknows.blogspot.com/2005/12/bill-maher-anti-vax-wingnut.html">hostility towards "Western medicine" and an affinity for "alternative medicine," a history of sympathy to HIV/AIDS denialists, and the activities of PETA through his…
drorzel | July 22, 2009(On July 16, 2009, I asked for volunteers with science degrees and non-academic jobs who would be willing to be interviewed about their careers paths, with the goal of providing young scientists with more information about career options beyond the pursuit of a tenure-track faculty job that is too often assumed as a default. This post is one of those interviews, giving the responses of David Warman, a computer game system designer.)
1) What is your non-academic job?
Title: Game System Designer. Function: Computer Systems Generalist. I did not know such a job existed until it found me last…
palmd | July 19, 2009Yes, this post is a repeat from long ago, but I was reminded dig it up after reading a piece at a friend's blog. Thanks for indulging me. --PalMD
If Bob Dylan provides the soundtrack for much of my life, then coffee provides the "smelltrack". I did not start to drink coffee until I was about 20. My best friend of 18 years told me I should learn to, as I might need it. He also told me to drink it black, because I might not always have cream and sugar, but I still might need the coffee. So, I started to drink it. Now, this was terrible coffee...institutional, stale, sour, just generally…
hrynyshyn | July 17, 2009If predicting climate trends was as easy as predicting the reaction of global warming pseudoskeptics there wouldn't be any deniers left. When I came across a new study in Nature Geoscience on the cause of the massive shift in the climate 55 million years ago, my first reaction was, "How long will it take before someone completely misrepresents this paper as evidence that undermines anthropogenic global warming?"
Not long. See here, here and here, if you have the time.
In the paper, Richard E. Zeebe of the School of Ocean and Earth Science and Technology at the University of Hawaii and his…
oracknows | July 15, 2009I tell ya, I'm gone for a few days, and the woo-meisters take over the store!
Seriously, I was really, really tempted to blog this over the weekend, even though I was at The Amazing Meeting and even though I had promised myself that I would not blog during the meeting. It was that tempting. Now it's a few days after I first learned about it, and I wondered it it was still worth blogging.
It is.
The story begins with, seemingly innocently enough, a press release by the Lymphoma Association:
We are delighted to announce the appointment of our new Chief Executive, Sally Penrose.
Sally joined us…
esiegel | July 14, 2009In the wake of the release of Unscientific America, a lot of discussion has ensued as to how scientifically literate we are, how scientifically literate we need to be, and what to do about science education in America. There are a lot of interesting perspectives out there, and I'd like to synthesize a few of the most important ones for you.
1. Journalists: There are some excellent science writers and journalists out there. (Miles O'Brien was one of my favorites.) There are also some horrendous ones, as Jessica Palmer helped reveal, who I would go as far as to call sensationalistic, lying…
gregladen | July 12, 2009Physioprof recently posted some comments on science and religion that I basically agree with.1 But I want to add an observation that I've been thinking about since this Pew Research report came out.
The current issue is that the average American thinks that an electron is larger than an atom, and some other stupid stuff. Back in the 1980s, the poster-concept for the stupidity of Americans was an exam given to school children in which the plurality of individuals placed Boston firmly in the middle of Tibet. This exam was given in Massachusetts. In those days, Geography was the bugaboo of…
drorzel | July 9, 2009I got a weirdly hostile comment to my popularization post last night:
You have some chutzpah. You are being paid, probably quite well, to do research! Journalists are paid, not nearly so well, to popularize research. It takes some nerve to take an extra year's salary, and to take time away from your real job---and then to complain about not being well-enough rewarded. If you want something to complain about, become a science journalist and see how well you are rewarded then. I'm sure you think that is beneath you, and that you do so much better a job---but the general audience you aim to…
eklemetti | July 8, 2009Two papers submitted, one to go. Keeps you quite busy, let me tell you.
Lava flow from a 2006 eruption on Mayon in the Philippines.
A few bits of news today:
A few more details about the ongoing watch of Mayon in the Philippines . There have been apparently no changes in the shape of the floor of the crater as you might expect if magma was rising underneath. However, there has been an overall inflation of Mayon since the unrest began a few weeks ago. PHIVOLCS will be checking the sulfur dioxide and carbon dioxide output of the volcano soon as well.
Lots of articles this week about the "…
drorzel | July 6, 2009Having repeatedly called for more popular-audience discussion of condensed matter physics (which is not my own field, but is the largest single division within the American Physical Society), I would be remiss if I failed to note a couple of really good efforts in this direction.
The first is last week's NOVA ScienceNOW segment on artificial diamonds and their technological potential. It's really cool to see time-lapse video of honkin' big diamonds being grown through chemical vapor deposition techniques.
The second is this New York Times piece on glass and the science of its use as a…

Setshot: Basketball for the Aging and Infirm: Rosters: Managing the list
"Overall, I like administering the list because I can virtually guarantee that any time I want to play, there will be others to play with. I also like the fact that I have some control over who gets on the list, and more importantly, who is excluded from it. Now don't get me wrongâthis isn't some velvet rope thing, and it certainly isn't as exclusive as this basketball list. I invited almost all the regular players at the gym. However, I was also able to subtly exclude a few bad apples by intentionally failing to…
