Music About Science

I have an opinion that might be unpopular around here: I don’t like music about science. My love of science and scientific knowledge cannot be impugned — my Ph.D. is all the evidence I need to make my case. I never would have made it through my 14 years of biology education if I didn’t love science. I even love boring science lecture — both hearing them and giving them. Music is also very important to me. I have been a casual musician for most of my life, and listening to music and making music are deeply fulfilling for me. There is a bunch of music out there that is about science, and it would be reasonable to guess that I would love this music. But I don’t. There is a time for music, and there is a time for a boring science lecture, but when I’m listening to music, what I want is not a boring science lecture.

Exhibit A:

Symphony of science is pretty popular. But let’s face it — this is literally just a boring science lecture that has been auto-tuned. The words of Carl Sagan, for example, are inspiring in their own right. I don’t think making them musical adds anything to them. If anything, I think his words are cheapened slightly by the gimmick.

Exhibit B:

I have a lot of love for Baba Brinkman, so I feel a little bit bad for listing him here. He is brilliant, great with words, and a good performer. I respect him a lot for using his medium to explain science. I particularly like the way he used this anti-evolution rally song as a base for this song about the science of political values and religion.

I got to see him perform once at an evolutionary psychology conference, and I really have nothing but love for him. For the times that I actually do want to listen to a boring science lecture set to music, I go straight to Baba Brinkman. But this doesn’t change the fact that his work is still essentially a boring science lecture, albeit spoken very rhythmically.

Exhibit C:

Hank Green’s “I Fucking Love Science” is cute. There are some clever lines, but it’s not what I want out of music. It is literal and a little bit lecture-ey at times. What I mean should be clear in a minute.

Please don’t misunderstand me — there is no judgement here. Musicians should write about whatever they want to write about, and people should listen to whatever they want to listen to. My feelings about the music I mention are just my own feelings. I also don’t mean to disparage any of these artists. I’ve tried writing music myself, and I can’t go around calling the kettle black.

This is not about what music I think people should or shouldn’t be writing and listening to, it’s just about what I want out of music. What do I want out of music? Some poetry. Some metaphor. The language of emotion. And would a drum solo kill you?

When I listen to music, I want to be able to identify with the emotions that are conveyed through the medium.

Take this song:

This song is reportedly about Kurt Cobain’s relationship with Tobi Vail, the drummer for Bikini Kill. You may not like this song as much as I do, but you will agree that at no point does this song, which is about a human relationship, sound like an anthropologist talking about the mating behavior of gorillas. The song is about the emotions, not the details. No boring lectures anywhere.

Kurt Cobain talks about his experience in this song without making the context perfectly clear. But it is deeply expressive and poetic, and it is exactly what I want out of a song.

Take another song about a relationship that ended:

Kris Kristofferson’s take on this topic has much more of a narrative style than Kurt Cobain’s. There is no question about what Me and Bobby McGee is about. But there is still poetry. He could have said, “Now she’s gone and I really miss her.” That would have communicated his point effectively, but there is no poetry to it. Instead, he chose to say, “and I’d trade all my tomorrows for one single yesterday.” Give me a minute to catch my breath.

I think the mistake that people make when writing music about science is talking like scientists instead of lyricists. There is a reason why we have scientists write our science, and musicians write our music. It has famously been said that, “Writing about music is like dancing about architecture.” Each of these media have their style, and limits to their application.

Here is what I would like to see: music about the experience of science, rather than the outcome of science. We have beautiful, poetic music about the experience of love, death, happiness, sex, jealousy, war, fatherhood, dissatisfaction, and basically every other human experience one could have. But very little beautiful, poetic music about science.

Consider, for a moment, Leonardo DaVinci. He was both a great scientist and a great artist. Remember that this was the guy who painted the Last Supper, the Mona Lisa, and the Vitruvian Man. If he was going to write a song about science, what would it have sounded like? “If the air passing over the top of a wing is moving faster than the air moving under the wing, it will reduce the pressure above the wing and create lift. La dee dee, la dee dah.” No, probably not.

Through my pursuit of science, I have experienced a wide range of emotions. Scientific discovery can be wonderful, beautiful, painful, emotional, and, at times, even exciting. Where is the music inspired by science that conveys these feelings?

You may disagree, or maybe I just haven’t heard the right music. What’s your favorite song about science?

Hot or Not

With Valentine’s Day coming up, I thought I’d do a post about the science of attraction. The purpose of this post is not to summarize everything that we know about what makes people attractive to one another, but to explain how we think about it.

First, it is important to realize that attractiveness is not a single trait. Attractiveness is what we call an “emergent property” of many different traits — that is, people may possess many different traits that all add up to making them however attractive they are.

Attractiveness may be broken down broadly into two divisions: physical attractiveness and non-physical attractiveness. Physical attractiveness is the aspects of a person’s body that you find attractive (hands, feet, face, whatever else you’re into), and non-physical attractiveness are the personality, values and social traits of a person.

Another way of breaking down attractiveness is into how broad the preference is for certain traits. Traits may be typical of humans as a species, typical of individual cultures, or individual preferences.

Species-Typic Attractiveness

These are the traits that humans, as a species, tend to find attractive in one another. We can talk about this the same way we talk about any other trait in any other species. For example, the American lobster (Homarus americanus) is usually a reddish-brown color, but about one in two million is instead a brilliant blue color. The presence of the blue lobsters does not change the fact that the typical color of the species is reddish-brown. It just means that there are exceptions to the norm. In humans, the most basic rule of attraction is that men are attracted to women, and women are attracted to men. This is the species-typic trait. But a few percent of humans are either attracted to people of the same sex, to people of any sex, or to no one at all. The existence of these traits — which are far more common than blue lobsters — does not change what is typical of the species, nor are people with these traits any less human. We can tell when an aspect of attractiveness is species-typic when it is common across cultures and throughout time.

The following are examples of other traits that humans tend to find attractive as a species:

Symmetry is a trait that is attractive not only to humans but to many other species. People of both sexes are more attractive when they have more symmetrical faces and bodies. Denzel Washington, people magazine’s sexiest man of 1996, was once found to have an almost perfectly symmetrical face.

Men are most attracted to women who have a low “waist to hip ratio” or a waist that is narrower than the hips. This is true of people across cultures and time. Waist to hip ratio (or WHR) is calculated by dividing the circumference of the waist by the circumference of the hips. Models and actresses commonly have a WHR of 0.65-0.75.  

Marilyn Monroe’s WHR was 0.63. Image from http://www.dailyhiit.com 

Conversely, women typically find men more attractive who have broad shoulders and relatively narrow hips.

Men and women differ in the size of the lower face, and this difference is important in attractiveness. Women with a smaller lower face (relative to the size of the upper face) and men with a larger lower face (relative to the upper face) are more attractive. This is fairly hard to imagine from my description, but the following pictures of Mila Kunis and Nikolaj Coster-Waldau should make it more clear. Pay close attention to the shape of the jaw, the width of the jaw, and the distance from the chin to the nose:

The most universally attractive non-physical trait is niceness. People of both sexes all over the world prefer romantic partners who are nice to them. This probably isn’t a surprise to anyone, but it has been confirmed by science.

Culture-specific Traits

Fashions for clothing, hair styles, facial hair, makeup, and jewelry are vastly different throughout time and space. High heels were originally a mens’ fashion that was later adopted by women. Nowadays a man wearing them is generally considered odd at best. Men used to show their wealth by wearing lots of necklaces and bracelets and rings. Men with wealth are still generally considered to be attractive, but modern, western conventions say “no” to all of the jewelry. Beards were in fashion when my father was young, then they were out for a few decades, now they’re coming back again. The perms of the 80s are mercifully gone, hopefully never to return.

Modern fashion often borrows things from fashion of the past, but completely adopting the style of past decades might be a little bit weird. Being weird typically makes one less attractive to others, unless you are in a culture that values being weird.

Some cultures find people more attractive when they are slim and some cultures like full figures.

The human population is the largest it has ever been, and the internet allows people to come together and form new cultures at a rate that has never been seen before. Adopting the conventions of a culture tends to make one more attractive to other members of the culture.

There is limitless variation to what individual cultures may find attractive, but there are no cultures that go against species-typic attractiveness by more than a little bit.

Individual Differences

Individual differences can cover both things that have been studied as well as the wide spectrum of unique things that people find attractive about one another.

People tend to like other people who are like them. This is called “assortative mating.” Political, moral and religious values can be a very important part of this. Liberals tend to date and marry liberals, Muslims tend to date and marry Muslims, vegans tend to date and marry vegans. The same goes for personality traits and even physical traits. There are obviously exceptions, but there is a clear trend.

How we feel about a person’s personality and behavior can influence how physically attractive we find them, and vise versa. If you have a negative experience with a person who is otherwise physically attractive, you will find them less physically attractive or even physically repulsive. The opposite is true as well.

Opposites don’t usually attract, but there are notable cases when they do. The most interesting case is probably the region of the immune system called the “major histocompatibility complex” or MHC. Humans and other vertebrates prefer mates who have different genes than their own in this region.

And sometimes there are just oddities that are unique to the individual. A friend of mine in college really liked guys wearing brown pants. There may not be anything substantial to explain about that.

This is just a primer on how scientists think about attraction. The few traits that I list are just examples and are by no means an exhaustive list of what we know (and there is still an enormous amount that we do not know). Of the things that I discuss, there are many nuances that I could not discuss for length. Indeed, whole books have been written on the topic. For more on this topic, see this book and this book and others. I plan to write more on this in the future, as well.

The point of this is not to tell anyone what they should or shouldn’t be attracted to. Everyone is different and the many aspects of attractiveness can interact in endless ways. People are attracted to whoever they are attracted to, even if it’s nobody.

What I hoped to accomplish here is to share a framework for how to think about the topic. The news is full of reports on new findings about human attraction. I hope it will be easier to put these studies into context after reading this post.

And try out this line tonight:

“Hey baby, I’m heterozygous at my MHC loci.”
