Career holding pattern

Carl Zimmer in the NY Times:

In 1973, more than half of biologists had a tenure-track job within six years of getting a Ph.D. By 2006 the figure was down to 15 percent.

I’ve always had a hunch that this was true…

Retracted Science and the Retraction Index:

A plot of the journal retraction index versus the impact factor revealed a surprisingly robust correlation between the journal retraction index and its impact factor (P < 0.0001 by Spearman rank correlation) (Fig. 1). Although correlation does not imply causality, this preliminary investigation suggests that the probability that an article published in a higher-impact journal will be retracted is higher than that for an article published in a lower-impact journal.

The charitable interpretation is that high-impact journals are willing to take higher risks in exchange for a bigger splash. And of course there is a not-so-charitable interpretation… a focus on big splash and getting a big scoop trumps scientific rigor.

Most scientists are in fact geeks

Science says:

In this Review, we hope to introduce scientists familiar with computational methods (geeks) to a selected set of interesting developmental problems…

A major educational goal in science should be to ensure that all biologists become geeks.

Inside the 50’s science fiction bubble

“American SF by the mid-1950’s was a kind of jazz, stories built by riffing on stories. The conversation they formed might be forbiddingly hermetic, if it hadn’t been quickly incorporated by Rod Sterling and Marvel Comics and Steven Spielberg (among many others) to become one of the prime vocabularies of our age.”

So writes Jonathen Lethem in his introduction to The Selected Stories of Philip K Dick. If you’re looking for that sci-fi conversation at its most hermetic, go read the 1956 celebratory anthology, The Best From Fantasy and Science Fiction, Fifth Series. The collection reads like a series of bad inside jokes, although three stories make it worth the $2.50 I paid for it at my favorite source of vintage sci-fi. (Check out the full listing of this anthology at isfdb.org.)

So where did this collection go wrong? Continue reading “Inside the 50’s science fiction bubble”

Sunday Poem

From the greatest science poem ever written, Lucretius’ The Nature of Things. The first stanza sets up the second, Lucretius’ rationale for doing, if you’ll forgive me the anachronism, science.

Sooner of later, you will seek to break away from me,
Won over by doomsayer-prophets. They can, certainly
Conjure up for you enough of nightmares to capsize
Life’s order, and churn all your fortunes with anxieties.
No wonder. For if men saw that there was an end in sight
To trials and tribulations, they would find the power to fight
Against the superstitions and the threats of priests. But now
They have no power to resist, no way to reason how,
For after death there looms the dread of punishment for the whole
Of eternity, since we don’t know the nature of the soul:
Is the soul born? Or does it enter us at our first breath?
And does it die with us, and is it broken down at death? Continue reading “Sunday Poem”
