Will Scientists Leave Hedge Funds and Return to Science?

An article in today’s New York Times, “A Rich Education for Summers (After Harvard), caught my eye.  It talks about how Larry Summers worked (one day a week, earning nearly $ 5.2 million in two years) at a large hedge fund “advising an elite corps of math wizards and scientists.”

The company,  D. E. Shaw & Company, was founded in 1988 by David E. Shaw, then a computer science professor at Columbia University.  According to the NYT article, “As part of Shaw’s rigorous screening process — the firm accepts perhaps one out of every 500 applicants — Mr. Summers was asked to solve math puzzles. He passed, and the job was his.”

I’m disappointed that the world of science wasn’t able to attract and retain these brilliant individuals over the past two decades.  If they had put their creative and analytical minds to work investigating mysteries of nature rather than mysteries of high finance, I think we might be better off today.

I’m encouraged that the tide may now be shifting.  In fact, according to the Shaw Group website,  “the vast majority of [David Shaw's] time is now devoted to his role as chief scientist of D. E. Shaw Research, LLC, in which capacity he leads an interdisciplinary research group in the field of computational biochemistry and personally engages in hands-on scientific research in that field. He also holds appointments as a Senior Research Fellow at the Center for Computational Biology and Bioinformatics at Columbia University and as an Adjunct Professor of Biomedical Informatics at Columbia’s medical school.”

Let’s hope that the values and traditions in the world of science (as compared to the values and traditions in the world of banking) do a better job of effectively channeling the talents, dreams, and energy of the next generation of bright students.

The Second Quantum Election?

In a blog post in mid-February, I introduced my (mostly tongue-in-cheek) theory that the Franken-Coleman election for the U.S. Senate seat from Minnesota is the very first “quantum election.”

Even while that contest’s recount goes on (and on and on), we may now be experiencing our second quantum election–the 20th Congressional District in New York.

At this point, although it’s still very early, it looks like yesterday’s vote may very well prove to be inconclusive, with ongoing disputes about absentee ballots and other voting irregularities. Once again, perhaps, the winner of this election will be determined eventually by whatever official body takes the final snapshot. As long as additional snapshots are being taken (e.g., recounts, court cases, appeals, etc.), the outcome will change on a somewhat random basis, as predicted by the probability cloud of voters.

In a comment on my previous post about quantum elections, Erik offered a critique of my theory.  Although I feel unqualified, as a philosopher and epistemologist, to argue with this critique, I must reiterate my belief that there is no “true winner” in these elections.  The “winner” is randomly determined at the moment the observer makes the observation.

If this trend toward quantum elections continues, the next round of national elections in 2010 will be a mess.

Perhaps some of the techniques that high-energy physicists use to better understand quantum mechanics can be applied to political science.  Here are two suggestions:

1)  The large hadron collider accelerates particles (e.g.  protons) around a big circular track and then bangs them together.  The results of the collisions provide valuable evidence that can be used to test various quantum theories.  What would happen if we accelerated two politicians (perhaps  a Democrat and a Republican) around the outer edge of the Capitol’s circular Rotunda and then collided the two politicians?  Perhaps this would knock some sense into them.

2)  And here’s another application of quantum theory to politics:  It’s a thought experiment called “Schrodinger’s Supreme Court Nominee,” based on the well-known thought experiment referred to as Schrodinger’s Cat. In this experiment, a Supreme Court nominee is locked in a box, along with a geiger counter and a tiny radioactive sample.  During this one-hour experiment, the nominee is both confirmed and rejected at the same time.  The nominee’s political fate is smeared out in a probability cloud.  (In the cat experiment, the cat is both alive and dead at the same time.)

At the end of the hour, the box is opened.  Only at this instant will the nominee “collapse” into a final state of either “confirmed” or “rejected.”  This procedure is just as effective as, and much faster than, today’s confirmation process for dealing with a nominee to the Supreme Court.

Any other ideas?

April Fool: Chemistry humor (?)

Several of my recent posts have hinted at the possibility that scientists have the full range of human emotions, including a sense of humor. (The humor can, admittedly, be somewhat warped.)

As further evidence, I offer this link to “The Periodic Table of Rejected Elements.”

I dare anyone who has taken a chemistry class to study this periodic table without smiling, chuckling or laughing out loud.

College Admissions: Acceptance or Rejection?

A blog article in today’s New York Times‘ parenting blog, “Motherlode,” has provoked some strong comments from readers–and raised a whole host of feelings and questions in me. In the article, “Waiting for College Decisions,” a father discusses his complex set of feelings and hopes for his only child on the day she receives her decision letters from various prestigious colleges on the East Coast.

Because two of my children (a high school senior and a college senior) are going through the very same process right now for college and medical school, I know that the decisions stir up strong emotions in both children and parents.

I admire the author of the blog article (his name is Charles Whitin) for his honesty and for his self-reflection.  I especially admire his final point that we should appreciate our children at this moment in time, while also being aware that change and growth is inevitable.  (For me, a similar moment happened when my oldest son started college.  Here’s a link to an essay, “Suddenly,  It’s Time to Say Goodbye,” I wrote about that experience.)

I’m sorry he got lambasted by several early comments.  I hope he has thick skin and keeps writing.

Here are some of the questions that come up for me on this college admission issue:

1) Is it wrong for parents to want the best for their children? (No)

2) What is the “best for their children”? (That’s a much trickier question.)

3) Which type of college provides the best education? For what kind of student?

4) Does a “big name” college make a difference in the direction of one’s life?

5) How much money and how big a financial sacrifice is a college education worth?

6)  As parents, we take pride in our children.  Isn’t that OK?  When does “taking pride” turn into “getting enmeshed”?

7)  Where are the boundary lines between caring too much, caring, and not caring enough?

I’m glad there is a place online where people are debating and discussing these issues.

Periodic Table in NY Times

The level of chemical literacy in the New York Times is definitely “on the rise.”  (He, he, he.)  (Pun intended. )  See the graphic accompanying this article.

In addition to looking at the graphic, you might want to read the article…. But don’t believe a word that is written.

I take strong exception to the author’s belief that a pun is a tawdry form of humor.  He’s obviously never spent quality time with a bunch of scientists in a bar.  (Oh, look at the author’s bio…. He’s a law student.  He probably doesn’t even like jokes about bar exams.)

I and a number of my scientist colleagues are inveterate punsters.  We have no shame.  No pun is too low.  And if it elicits a groan from the audience, that’s even better.  (Here’s a link to some really bad chemistry puns. And here’s another link to more bad chemistry puns.)

Why am I writing about puns in a blog supposedly devoted to science and/or parenting?  Is there a link between science and puns?

Perhaps.  The kind of thinking required for both activities involves looking at an object or a word from several perspectives at the same time.   The mental agility required to play with words (while punning) is not that different from the mental agility required to play with molecular structures (while visualizing chemistry in your head).

One of my favorite parts of organic chemistry was learning about the concept of chirality and stereochemistry.  Two molecules with the same formula and the same configuration of bonds can actually be quite different, because they can be “mirror images” of each other. In my memory, I can still see my St. Olaf College chemistry professor, the legendary and iconic Wes Pearson, holding up his left hand and right hand to introduce the concept of “handedness” as it applies to many organic molecules.

One of the most dramatic examples I recall from that college class is the anti-nausea drug, thalidomide.  Wes Pearson showed us that there can be two stereoisomers (also called “enantiomers”) of this chemical compound.  One version of this molecule is effective in treating morning sickness.  The other version, however, is teratogenic, which means it can cause birth defects.  The tragic story of thalidomide (used in more than 40 countries in the late 1950′s) certainly got our attention during that lecture, and I’ve been fascinated by the concept of stereochemistry ever since.

So, the moral of this blog post is that puns are linguistic enantiomers.  (No pun intended.)

(Part 2 of this article will consider the relationship between puns and parenting.)

Don’t Forget the Boys

Don’t forget the boys.  That’s the message in Kathleen Parker’s op-ed piece, “Bring the Boys Along: The White House Council Obama Forgot, in the Washington Post.

Although she makes a few snarky comments along the way (that’s one of the things that columnists need to do to keep up their readership), I agree with the main theme of her article.

As a society, we’ve done an excellent job in the past generation of increasing opportunities and expectations for girls.  Now it’s time to realize that boys need our help, too.

Parker refers to suicide rates, which are much higher for boys than girls, as one indicator of the need for attention to boys in our society.  She could also have pointed to graduation rates, incarceration rates, and lifespan statistics.

The author who has done the best job documenting this issue is Dr. Warren Farrell. His books, such as The Myth of Male Power, are thought-provoking and should be required reading in any class that addresses gender issues in American society.

The topic is fraught with political correctness, myths, and ideology, so it’s one that I rarely bring up.  As the father of four boys and as a man who’s spent quite a bit of time in a non-traditional role (i.e., primary parent), I have strong opinions on the subject.

However, it really would take an entire semester-long class to begin to explore the issue in a way that does justice to the topic.   It would take an entire lecture to just lay out the caveats, the apologies-in-advance, and the careful definitions of terms.  Only after that opening lecture would many listeners begin to put aside their ingrained beliefs and open their ears and minds.  (Just remember what happened to Larry Summers, then-Harvard-President, when he clumsily raised some questions about women-men differences in math and science.)

As a scientist who’s written frequently on the subject of women in chemistry, I’m well aware that there are many subtle societal messages that represent barriers for girls and women in science.  And some of the barriers aren’t so subtle.

Any good discussion needs some statistics, so here are a few for the chemistry profession:

  • The percentage of bachelor’s degrees in chemistry earned by women has risen from 29% in 1981 to 55% in 2007 (statistics from the National Science Foundation and  Chemical & Engineering News, 12/3/07). During the same period, the percentage of Ph.D.s earned by women increased from 16% to 38%.
  • The median starting salaries for women and men bachelors-degree chemists are essentially equivalent ($36,300 vs $37,000), as are the salaries for women and men masters-degree chemists ($49,000 vs $46,000).  (These 2007 statistics come from Chemical & Engineering News, 6/2/08.) The data for doctoral-degree chemists are more difficult to interpret, with some years showing parity and some years showing significant disparity.
  • These significant increases in the number of women studying chemistry have not yet translated into comparable numbers among the leadership of the chemistry community, especially in academe. According to 2007 statistics, just 15% of chemistry professors at the top 50 universities are women. (The breakdown by rank is 11% full professor, 22% associate professor, and 22% assistant professor).

Another good place to go when starting a discussion is to consult some of the scientific leaders who have thought deeply on this subject.  Among the scientists who have impressed me with their thoughtfulness and shaped my thinking are Geri Richmond, Dick Zare, Helen Free, and Jo Handelsman.  If you get a chance to hear or read their thoughts on women and science, I highly recommend it.

While there’s still plenty of work to be done in making the world of science more friendly for women (and for men who want to be involved parents), an even more important issue in the coming years is going to be finding ways to advance the education and opportunities of both girls and boys in American society.

Scientists are human, too.

One of the themes of this blog is that scientists enjoy (and suffer) the same emotions, illnesses, ecstasies, depressions, and everyday life experiences as every other human being.

The process of science—with its values of measurability, repeatability, objectivity, logic, and skepticism—does an admirable job of dampening the “non-scientific” influences brought by a human being. But those values can’t be ignored or eliminated. And if it were possible to eradicate those pesky human qualities, we’d also have to eliminate curiosity, the search for meaning, the appreciation of beauty, the desire to make the world a better place, and the drive for truth—the very motivations that underlie science itself. That wouldn’t be a good trade-off.

Just remember that science is a process. A scientist is a human being.

In today’s Washington Post, an op-ed piece by endocrinologist David Shaywitz, “When Science is a Siren Song,” forcefully makes the same point.

More on “Implicit Bias”

My post from earlier today, “Some of my best friends are …,” discusses my personal experience with the idea of unconscious bias. The same topic is discussed in Charles Blow’s column in today’s New York Times.

Some of my best friends are …

Some of my best friends are …

…. unconsciously biased against certain social groups (e.g., Women in Science; African-Americans). And I am, too.

At least, that’s the claim by three psychologists from Harvard University, the University of Virginia, and the University of Washington. These psychologists study a phenomenon known as “implicit association.”

Here, for example, are two of the findings from these studies:

• People are often unaware of their implicit biases. Ordinary people, including the researchers who direct this project, are found to harbor negative associations in relation to various social groups (i.e., implicit biases) even while honestly (the researchers believe) reporting that they regard themselves as lacking these biases.

• Implicit biases predict behavior. From simple acts of friendliness and inclusion to more consequential acts such as the evaluation of work quality, those who are higher in implicit bias have been shown to display greater discrimination. The published scientific evidence is rapidly accumulating.

If these findings are valid, they have profound implications for the way we make career decisions for ourselves and for others. The findings offer support to the idea that a slight skewing of many minor and major decisions (by interviewers, reviewers, colleagues, etc.) gradually add up, over time, to a measurable decrease in the number of women and under-represented minorities in the scientific workforce. (See, for example, Virginia Valian’s book, Why So Slow? The Advancement of Women.)

As a member of the “enlightened” generation that came of age in the 1970s, I find this hypothesis disturbing and these findings problematic. After all, I’m objective, fair-minded, sophisticated, sensitive, rational, and data-driven. Right?

Before I accept the notion that I’m unwittingly harboring sexist. racist, or ageist biases, I’d like to see some evidence, please. Show me the data.

“Take this test,” the researchers respond, inviting me to the Project Implicit website.

So I take the tests.

Guess what? The tests find:

• “Your data suggest a slight association of Male with Science and Female with Liberal Arts compared to Female with Science and Male with Liberal Arts.”

• “Your data suggest a strong automatic preference for European American compared to African American.”

I’m not proud of the results, and I decide not to take any more tests right now. I don’t really want to take more tests and then be told about my biases in other areas (including weight, religion, age, Arab-Muslim, etc). Besides, the tests require concentration and time (actually only about 10 minutes per test).

Do I find my results distressing?
– Yes

Do I believe the validity of the test?
– Maybe. I’m not a psychologist, and I haven’t studied the peer-reviewed literature on this topic. Is there a scientific consensus on this subject?

Does it make me think?
– Absolutely.

Does it make you think?

It Happens Sooner Than You Expect

While finishing my first cup of coffee this morning, I realized that my adolescent had not returned at all last night. I knew he was getting more restless every day, but I never expected him to stay out all night. I searched the house and the neighborhood, calling his name. I put out an online appeal on craigslist.org. Can anybody help me? Have you seen him?

It was probably his hormones, I realized. Puberty arrived earlier than I expected. “You should have taken action sooner,” I scolded myself. But…I thought I had more time, so I hadn’t made it a top priority. Did I wait too long? Would he be safe? Would others be safe around him?

At 11 am, he finally came home. I was relieved…until I saw the blood around his ear.

Leo, my nine-month-old, orange-and-white tabby cat, had been in a cat fight. After I cleaned him up and assured myself that he was not seriously injured, I called the vet and made the appointment I had been procrastinating—Leo will be neutered next week. Until then, he’s not going outside, no matter how loudly and often he howls.

A year ago, my previous pet cat, the beloved 13-year-old Midnight, had never returned home after one of his nightly outings. Although that incident was unrelated to cat puberty, it was nonetheless a very traumatic event for me and my boys. This morning, when Leo didn’t return, in spite of winter temperatures well below freezing, I’d experienced a flashback to last year’s heartbreak. With Leo, why hadn’t I taken action sooner?

Leo’s adolescent urges will be tamed pretty easily, with just a little snip. With human teenagers, however, that option is not available. At least, I don’t think it is…

When my sons went through puberty, I also procrastinated before taking action. I assumed that school and church would educate them properly about matters related to sex, morals, and relationships. Maybe I wouldn’t have to have “the talk” with them.

The schools and the church did their best, but, to be honest, those institutions provide little shelter in the hurricane of our modern culture. From TV sitcoms to movies, from MySpace to mp3 lyrics, our children are buffeted by strong societal winds as they enter puberty. As parents, we need to voice our values, knowledge, and wisdom to them—early and often.

As my sons can tell you, I did eventually have “the talk” with each of them, but it was brief and awkward. As a father-son talk, it was true to stereotype—short on details, long on unspoken assumptions, with minimal eye contact. It was not one of my finer moments as a Dad, and I regret not doing it sooner or more conscientiously. (Is this an easier job for Moms?)

As humans, we don’t have to be slaves to our animal instincts. Teenage boys don’t inevitably tomcat around, and teenage girls don’t go into heat. But if you’re a parent of a child on the cusp of adolescence, please don’t underestimate the power of puberty.
