How popular is your element?

XKCD inspires many people. Now it has inspired a periodic table geek

XKCD’s latest is a calendar of meaningful dates based upon how often a date is represented in English-language books since 2000. Anders Sandberg, a neuroscientist at Oxford University, has taken inspiration from that calender and his love for yttrium to construct a new kind of periodic table. It’s based on how popular each element is on the interweb (roughly based on Google search hits).

As Anders explains:

Most popular were, perhaps unsurprisingly, gold (2.7 billion) and silver (1.9 billion). Lead got into third place (1.4 billion), perhaps due to the fairly common verb “to lead” rather than its heavy charisma. Why tin is so popular (1.1 billion) beats me.

Least popular are the transuranians, with Bohrium (40,600), Livermorium (106,000) and Flerovium (118,000) as the least popular. These might suffer a bit because they are recently named and people might still remember them with their old names. But they are still fairly obscure outside connoisseurs of heavy nuclei. Why Meitnerium is so popular compared to the others also beats me.

Robert Munafo, an independent American researcher, points out that tin’s popularity might be down to its usage in Vietnamese. Of course, as Anders accepts, his algorithm based on two hours of work isn’t perfect. There may be a way to semantically weed out non-elemental usage of these words, and I do hope that someone starts working on that.

Till then, I take solace in the fact that Osmium seems to be doing just as well as Polonium and Thorium. How is your favourite element doing?

Why not to do a PhD if you want to become a writer

I got an email from a friend who is a chemical engineer that said: “I am considering doing a PhD in marketing”. The last I spoke to him he wanted to pursue a career in science writing. So I inquired whether he had changed his mind.

To which he said no. “I want to stay in academia so that I’ll get the time to read and write as much as I really want to. Getting into grad school seems like the only way. I really don’t want to get sucked into a corporate job that I would hate doing.” On reading that alarm bells started ringing in my head and I couldn’t not stop myself from telling him that what he is thinking of doing could go horribly wrong.

Too many people end up doing a PhD because it is an easy option. Leaving the academic bubble is hard when the grad school cookie is on the plate. There are also perverse incentives for universities to let its undergrads stay on to a PhD and even a postdoc. You could read all about it here. I’ll focus on my friend’s aim to become a writer, and why getting a PhD in the sciences or social sciences is not the best route to do that.

I feel the urge to share the conversation I had with my friend because, if I had known before choosing to go grad school that science writing is what I would like to do, then I would have taken a different path. Also because my friend has this romantic notion that academia gives you the freedom to pursue things beyond what you study, and that that is the key to becoming a good writer. Both those assumptions have a grain of truth in them but they are far from the ideal solution to where my friend wants to get to.

First, I can see why a PhD in marketing might have seemed tempting. He said: “The interesting thing about marketing is that you can operate from literally any area: communications, cognitive behavior, or decision making”. Second, given his scientific background and his goals I can also relate to it when he says: “I couldn’t stand the thought of doing a PhD in chemical engineering”.

But I suspect that few science students understand what a social sciences PhD entails. Some of my closest friends have pursued a PhD in social sciences, so I know.

First, there is rarely a “research group”. Most supervisors have only a handful of students who work on very different areas of a subject. So you lack the support network that science grad students have. Only when you spend day after day in a library, most of the time alone, trying to get through tons of reading do you realise the value of having friends standing by you all day in a lab.

Second, supervision in the social sciences is usually quite light. What I mean by that is that a social sciences student has a lot of freedom about how to approach the chosen subject. This is fantastic if you love your subject, you can dive in to different areas and emerge with many ways in which you could reach the end point.

That is not how a science PhD works. In most cases, a science PhD starts with a project that your supervisor has in mind and has already charted out the possible route to start with.

Also, the number of times a grad student’s work is reviewed in the social sciences tends to be, on average, much less than the number of reviews that happen in the sciences. For instance, I’ve never heard of a “group meeting” in the social sciences. Whereas I’ve never not heard of group meetings in the sciences.

This is important because it allows a science student to direct their work on a much more regular basis than a social sciences student gets to.

Third, social sciences students end up not including months and months of work in their final thesis. While that may happen to science students too, at least in their case, a negative result is a result after all. Despite negative results not being reported in academic publications, few fear not reporting legitimate negative results in their PhD theses.

I’ve spent a chunk of this post comparing a social sciences PhD with a science PhD because I feel that it is nuts to believe that a social sciences PhD will give you the time to do other things that will help you become a writer compared to an all-consuming science PhD.

The other belief that needs to be crushed is that academia is a cushy job, that academics get the time to pursue things beyond their subject area as much as they like, and that the university atmosphere is the only way to pursue the intellectual curiosity of a writer.

There is a grain of truth in all that but it is not a realistic picture. Well-established academics indeed may be in that position, but not young academics. While many academics do end up writing hugely enjoyable books, it is rare that a young academic does that. Academia today is more competitive than it has ever been, not least because there far too many PhDs and post-docs wanting that illusive tenure-track position.

This brings me to the most important point: In my opinion no one should pursue a PhD if they don’t love the subject. To be able to successfully get a PhD from a good university, you really need to know what you are doing. It takes dedication, perseverance and patience. PhD in any subject area requires you to dive deep into what you do. This is why it takes the 3 to 7 years (or more than that) to get a PhD. This is especially true if you want to become an academic at the end of it.

So, my friend asks, how do you become a writer then? I heed the words of Ed Yong:

1) Pull your finger out and work really hard. Stay up late. Practice. Sacrifice your social time. Churn out a crazy amount of output. Practice. Enter competitions. Practice.

2) Give people a reason to read you. There are plenty of competent writers and not enough time to read them. Maybe you are the go-to person for a topic. Maybe you write like an angel. If you want to stand out, stand out.

3) Tell people about yourself. Promote your work. If you want to be recognised, then it’s not enough to be good and shout into the ether. And I don’t mean in a narcissistic, self-aggrandising way. You don’t even have to directly point to your work. Just let people know you exist.

4) If you are lucky enough to be given an opportunity, grasp it as quickly as possible because the momentum fades. If you haven’t been given opportunities, maybe you should try to create some. If you’re not part of a network (and want to be; loads don’t), are you sitting around waiting to be invited or did you cold-call and ask for feedback?

5) If it’s been several years and you’re not getting anywhere… that’s about right. Building a reputation takes time. It is demotivating and miserable in the meantime. Suck it up. Do what you do because it makes you personally fulfilled. Don’t expect a windfall; that will come after a lot of work.

6) Go to 1.

But to be able to do what Ed is suggesting requires you to have a source of income to pay your rent and bills. And so my final advice to my friend was to get a day job that will allow him to pursue writing as a night job. That day job should not be a PhD. It may pay enough to sustain you, but it isn’t easy to balance writing with a PhD (although some can!). While a PhD can give you many valuable skills to be a science writer, you might be able to gain those skills on your own through practice (many have demonstrated that).

In short, a PhD is not the answer to becoming a science writer. A PhD is a hugely satisfying (stuffed with a lot of frustration in the middle) endeavour and must be pursued only if you love the subject. While quitting a PhD and doing something else is always an option, it is not as easy as quitting a job and getting another one.

Disclaimer:

1. My opinions are based on a limited sample size. What I’ve written is based on the experience of spending four years as a graduate student at Oxford. Thus, it is quite possible that I’ve got many things wrong.

2. I wrote this in response to the email from my friend. So the advice is quite tailored to his case. Just keep that in mind before you draw any general conclusions from it.

Don’t overthink social media

Ed Yong distills the notion of self-promotion through social media in one sentence:

The way to think about this is to map any [online] behaviour onto the physical world.

And here is the explanation in full:

So, would I tweet about something I wrote. Yes. That is basically telling friends about something I did that I’m proud of. Who wouldn’t do that in real life?

Would I tweet about something I wrote multiple times? Yes. In the same way that I would tell the same anecdote to different groups of friends. Different people are online at different times. If the same person happens to hear the same anecdote, who cares?

Would I tag friends into tweets, or DM them about it? Rarely, but sure, why not? Same thing. This is just specifically going up to someone and telling them about something I did that I’m proud of. I’d wouldn’t do this for everyone, but for people I have an established relationship with, why not? I wouldn’t rankle if someone did it to me.

Would I tag strangers into tweets? Probably not unless under exceptional circumstances. Would I tag a group of influencers into a tweet, many of whom I’ve never spoken to before or follow? No. Hell no. That would make me the guy at the party who only goes up to the famous people and shouts loudly about themselves. Who wants to be, or speak to, that guy?

Would I reply to the tweet of someone I follow but have never spoken to, alerting them about a post I wrote that was related to what they tweeted about? Absolutely. What, you’ve never started a conversation with a stranger riffing off of what they said?

It is social media. Online, too, the same rules apply.
