Trusting other scientists (Sames-Sezen follow-up).

At the request of femalechemist, I’m going to revisit the Sames/Sezen controversy. You’ll recall that Dalibor Sames, a professor at Columbia University, retracted seven papers on which he was senior author. Bengu Sezen, also an author on each of the retracted papers and a graduate of the Sames lab, performed the experiments in question.

Sames says he retracted the papers because the current members of his lab could not reproduce the original findings. Sezen says that the experiments reported worked for her and for other experimenters in the Sames lab. Moreover, she says that Sames did not contact her about any problems reproducing the results, and that he asked the journals to retract the papers without letting her know he was doing so.

I am not now, nor was I ever, an organic chemist, so I’m not going to try to do the experiments myself (repeatedly, with appropriate consultation of the people who developed the original protocols) to see who’s right. That’s not the kind of light I can shed on this case. However, I can break down the key issues at play here:

Online chemistry resources from the Journal of Chemical Education.

Another dispatch from the BCCE:
The Journal of Chemical Education (or J Chem Ed, as we call it in the biz), is, in fact, targeted to an audience of chemical educators. Its website has the online version of the journal, plus some resources for teachers of chemistry at the <a href="http://jchemed.chem.wisc.edu/HS/index.htmlhigh school and college levels.
But, it also has a passel of goodies that anyone with even a passing interest in chemistry can love.

More from the BCCE: Atkins and Harpp on talking chemistry with the people.

It was another full day at the BCCE, starting with an excellent plenary address by Peter Atkins (who wrote my p-chem text, plus dozens of other books) and David Harpp (of the Office of Science and Society). Each of them spoke about the best ways to talk about science with people who are not scientists, science teachers, or science students. Some highlights after the jump.

Day 2 of the BCCE: some notes.

I’m blogging again from the lovely Vienna Cafe in West Lafayette, Indiana, at the end of Day 2 of the BCCE. I gave my own talk this afternoon as part of symposium session on incorporating ethics in the chemistry curriculum (along with 5 other very interesting talks). I think it went well, but I always enjoy conferences more when I’ve finished my presenting and can be an undistracted audience for the other presentations.
Below the fold, some of the things I learned in todays various talks and events:

Famous chemist trivia.

Greetings from the BCCE! Well, actually from a cafe down the street from the BCCE, since the wireless accounts that were supposed to be set up for conference goers are not currently functional. (The lengths to which I’m willing to go to satisfy my readers!) The immediate result of this situation is it will take comments a bit longer to go up.
But, I have gathered (from the talks on how to convey the “nature of science” to students) some fun facts about famous chemists.

Which comes first?

This morning, I finished making the slides for a talk I’m giving at the BCCE at Purdue next week. (Any of you chemists or chemical educators in the audience planning on being there?) I feel very proud of myself for having the slides written and ready to use days before I even board the plane. I’m even sufficiently enthusiastic that I may just start writing a paper-version of the content I’ll be giving in my talk.
That brings me to my question for academics and others who work in the media of “paper” and “presentation”:
Which do you typically write first?
Do you write a paper first and then adapt it to a suitable format for presentation*? Or do you write your talk first and then use it as the basis for a paper (which might be more lengthy, formal, detailed, etc.)?
Is this a pattern you’re happy with, or do you ever think you’d rather do it the other way around? (If the latter, what exactly is stopping you or has stopped you from doing it the other way around?)
_________
*Opinions vary on what counts as a suitable format for presentation. There’s this practice in philosophy where, rather than giving a talk, a philosopher will read the audience a paper. This sometimes happens even in instances where the paper has circulated to audience members in advance — which means you can watch the presenter reading his or her paper while audience members read along on their own photocopies of the same paper.
Maybe it’s my early training as a chemist (since, in chemistry, no one gives this sort of presentation), but I have always found the reading-to-the-audience format offputting. But, it’s one where clearly the writing of the paper comes before the “writing of the talk”.

Friday Sprog Blogging: what does the “2” stand for?

Dr. Free-Ride: So, I found a little café table for the back yard.
Dr. Free-Ride’s better half: A good one, or one that’s going to fall apart?
Dr. Free-Ride: Well, I made a point of getting a cast-iron one rather than one made of elemental sodium; those aren’t so weather-proof.
Elder offspring: You know, you still have to figure out a sprog blog for tomorrow.
Dr. Free-Ride: Yeah, don’t worry, we’ll start asking you questions in a moment.

Reproducibility and retracted papers.

From The New York Times:

A chemistry professor at Columbia University who in March retracted two papers and part of a third published in a leading journal is now retracting four additional scientific papers.

The retractions came after the experimental findings of the papers could not be reproduced by other researchers in the same laboratory.

It’s a problem if published experiments are not reproducible — but what kind of problem it is might not be clear yet.

You can take the girl out of the lab …

It’s time for another spin of the “Ask a ScienceBlogger” wheel! The question this time is:

Assuming that time and money were not obstacles, what area of scientific research, outside of your own discipline, would you most like to explore? Why?

You may recall that I chose to leave chemistry for a career as a philosopher of science. Near the end of my time in chemistry, I was pretty anxious to leave the lab behind — preparing solutions, calibrating (and repairing) pumps, washing glassware, etc. So I’m actually a little surprised at my own answers to the questions, since I find myself drawn back to experimentation.

Rational (cocktail) synthesis, in need of empirical data.

Ah, the power of the internets! Without them, how would I ever have discovered The Mixilator?
The Mixilator is hosted by The Internet Cocktail Database. It presents you with a form asking you to specify your cocktail variety, hour, strength, level of complexity, and special characteristics. It then returns with a recipe for a cocktail.
But, the recipe that is returned to you is not a pre-existing coctail from the CocktailDB. Oh no, it is much more wonderful than that! The Mixilator randomly generates your cocktail recipe using an algorithm based on the theories set out by David Embury in his 1948 book The Fine Art of Mixing Drinks.
We are indeed living in a new age of wonders!
But we who care about science are not satisfied with the algorithmic implementation of a theory. We are the reality-based community. We seek empirical data!
