TED talk Q&A live online

On Friday, Thursday, December 1, at 1:00 p.m. Eastern (US) time (18:00 UTC) I’ll be doing a live online chat about asteroid impacts and astronomy at the TED website. This text-based chat is open to anyone; all you have to do is register which is free and only takes a moment.

The chat will revolve around my TED talk called "An Asteroid Impact Can Ruin Your Whole Day", which I gave here in Boulder in September. You can watch that talk online, which I suggest you do if you want to come to the chat. It’s only 14 minutes long, but it does feature me gesticulating a lot.

If you’re curious what it will be like, my Discover Magazine co-blogger Sean Carroll did a TED chat in May 2011. This is a fun way to interact with people, and I’m looking forward to it, so drop on by and ask a question!


Slash the Bad Astronomer!

OK, don’t slash me. But I have been Slashdotted!

Slashdot is one of the biggest news aggregators/social networks on the web, where users link to interesting stuff they find, and others can leave comments. They also do interviews, kinda: they line up an interviewee, people leave questions, and then the interviewee answers them en masse. They asked me to do this a few weeks ago, and now my responses are up at Slashdot!

This was a lot of fun. The questions were pretty varied, from JWST (of course!) to where we should be sending probes to look for extraterrestrial life. I tried to keep my answers relatively short but still give folks something to think about. It’s an interesting exercise, trying to do this all in one shot. I found myself thinking pretty hard about how to respond, and then, later, how to best ice down my aching wrists from typing so much. I wish I could’ve answered all the questions, but I’d probably have fatal carpal tunnel syndrome if I had.

My thanks to everyone at /, and to Tim Lord for setting this all up.


Mea culpa: About studying science to get a job

This morning, I posted an article where, looking at a database from the 2010 Census, I concluded that your chances of getting a job are a lot better if you major in a science field. Four of the ten college majors with the lowest unemployment rates were science-related.

It turns out I made some errors in the post. One is a logical fallacy, the other in my structure and wording, implying something I didn’t mean to. These were pointed out to me by a reader who makes several valid points, but then falls into errors of his own. This is worth sorting out, so I want to take a moment to show what’s what.

I was taken to task about my post on Twitter by Noahpinion, who pointed out (in tweets here and here) that many fields of science had higher unemployment rates. I replied that the numbers he quoted (6-7%) were still below the national average.

That was a mistake on my part. Noah pointed out that I was using 9% for the national unemployment average, but that’s overall unemployment. A better figure to use would have been 5%, which is the unemployment rate just for college graduates! That is correct; I should’ve used the lower number.

I’ll note that this doesn’t change the point I was trying to make: that a large fraction of the college majors with the lowest unemployment numbers are science-based. But that’s where I think I made a bigger mistake.

In my zeal to write something short and pithy for Twitter (and the post headline), I made it sound like getting a science degree will guarantee you a job. "Want a job? Study science" is the headline, and it’s misleading. In the post itself I tried to make it clear that in reality, studying science (or at least the fields of science I listed — astronomy, pharmacology, and others) would increase your chance of getting a job. I even mentioned that you may not get a job in the field you studied, but I do think that getting a science degree prepares you better for the job market. If done correctly, you learn things like programming skills, writing, communicating, and so on. I said a lot of my friends got astronomy degrees and went into different fields that were related to their skills developed (though they had PhDs — which in some ways makes it harder to get a job… but that’s another story).

Anyway, Noah wrote an interesting article about this on his blog, pointing out where I went wrong. Fair enough. He says that what I am saying is that the problem with finding a job is on the supply side: we’re not training enough people with employable skills. He then says:

BUT, the story Phil is telling is just not right. Not right at all. It implies the same thing that many conservatives are saying openly – that the root of unemployment is on the supply side. That our high unemployment rate is simply due to the fact that we’re not teaching kids the right stuff, or maybe that kids are choosing wimpy majors.

This is certainly not at all what I meant, though after re-reading my post, I can see where someone might easily read that into what I wrote. I should’ve been more clear, and that’s my fault. Of course I understand that it’s not that there are jobs sitting out there unfilled, waiting for science majors to take them. I just didn’t say that specifically in the post, and I should have. I blew it.

However, I do disagree with what he says next:

Earth to Bad Astronomy: your short-list of fully-employed science majors is totally cherry-picked.

That is unfair. Cherry-picking is when you arbitrarily pick things that make your position look stronger, showing them out of context. I looked at the ten majors with the lowest unemployment rates; the only arbitrary thing is the cutoff I chose. As I looked down the list, past those ten, I saw plenty of other science-based majors. Ten seemed like a decent cutoff, and I did not pick it to make my position look better. So arbitrary, yes; but cherry-picked, no.

Then Noah says:

Overall, science and engineering majors are suffering right along with everyone else in the country, because that is what happens when we are in an economic depression. And all those astronomers who have plenty of jobs? Guess what: they’re employed because they work for the government. Yep, that’s right, the same government whose ability to provide employment Phil laughs at.

This is both incorrect and a gross misrepresentation of what I wrote.

Of course science majors are suffering along with everyone else. I never said otherwise. I did say, or at least tried to say, that some fields of science are clearly better choices if you want to maximize your chances in the job market.

I also take exception to Noah’s comments about the government. First of all, I didn’t "laugh at" the government, I was pointing out that certain ideologues in government want to suppress science and science education. That’s a huge difference! I also never mention the government’s ability to hire people, let alone laugh at it. If anything, I link to a post I wrote where I show that governments suppressing science (as Louisiana governor Bobby Jindal did) leads to losing jobs, or at least losing revenue.

In that sense, Noah is doing the same thing he accuses me of: over-generalization.

Second, he says that astronomers are employed by the government, but doesn’t give evidence for that. According to this site, the majority of astronomers work in academic fields; Universities and so on. Of course, many of them have NASA and/or NSF grants, but in many cases the funding comes from non-government sources. But these astronomers don’t work for the government, they work for academia.

And how does this matter, anyway? Whether the government is hiring, or private industry, those people who majored in those fields got employed, and that was my point in the first place.

So, to sum up:

I made some errors in that article. The biggest, I think, is that I implied strongly that getting a science degree guarantees a job. That is incorrect, and I’ll add an update to that post as soon as I’m done here. However, my case that getting a science degree, at least in certain fields, is beneficial to getting a job is still on the table. It would be interesting to pick some other field (the legal system, maybe, or engineering?) and see if the unemployment rates are comparable to that of science majors. Maybe all fields have some distribution of unemployment. However, and this is important, the fact still remains that of the ten majors that have lowest unemployment, a large fraction are science related.

There’s not much we as individuals can do to turn the economy around or create new jobs, but we can at least maximize our own chances of getting what jobs are out here. These numbers are an indication of how to do that.


Wrap up: Donors Choose

I want to thank everyone who contributed to the Donors Choose science blogger challenge. Because of you all — 90 people who donated in total coming from this blog and my other outlets like Twitter and Google+ — we raised $5,887, and 2,480 students will see new science materials in their clasrooms!

Wow.

Think about that. Nearly 2500 students, positively affected by strangers who simply want more science taught in school. Some of the donations were for a little bit, and some for a lot, but they all added up to a huge effect on those kids’ lives.

So thank you to every who participated, and know that you have been a great help. And for those of you who donated in the last couple of days, I’ve been told the matching donation email has been sent. Check your inbox, and in just a minute of your time you can double your impact.

Y’all are great. Thanks again.


Ask me something on Slashdot!

Slashdot is a news aggregator site where contributors submit interesting stories about science, tech, and assorted geekery. It’s one of the oldest and biggest social network sites on teh tubez*, and still one of the best. I go there every day to see what’s buzzing. My own humble (ha!) site is linked from there every now and again as well, and I’m always happy when it is.

Every week or so, Slashdot does an interview with someone online. They open up questions, collect a few, and send them to the interviewee to answer via email. So guess who they just asked to participate?

That’s right! Rory Calhoun! No wait, it was me! They’ve opened up a page where you can leave a question. You don’t have to register to ask a question, but if you like fresh techy news, you should sign up anyway. Feel free to ask anything, though bear in mind I’ll be writing out the answer, so something like "Why is the Universe expanding?" might be more text than I’m willing to write and you’re willing to read.

But, to save you time, here are some answers so you don’t have to ask basic questions:

1) Yes, I’m married.

2) I worked on Hubble for ten years, but now I write about it.

3) No.

4) When I write about not wearing pants most of the time, I’m not kidding.

5) 13.73 +/- .12 billion years.

6) It’s a tough choice, but I’d have to say either Wil Wheaton or George Hrab.

So there you go. I hope that helps. Head on over to Slashdot, see what others have asked, and then leave your own question! And my sincere thanks to Slashdot for asking me to be a part of this. It’s an honor.

I’ll add that questions left in the comments on this very post won’t be part of the Q&A; you have to go to Slashdot and write it there. Thanks!


* In fact, in the olden days of the web, when a site got linked by Slashdot it frequently overloaded the server, jamming it and making site loading very slow. This became known as "getting slashdotted" and it happened to me a few times way back when, before the Hive Overmind Discover Magazine started hosting my blog on a beefy server that can handle the load better.


Last call: Donors Choose

For the past couple of weeks I’ve been participating in a science blogger challenge with Donors Choose, to raise as much money as we can to go to classrooms that need science equipment.

The challenge ends Saturday at midnight Eastern US time. I just got a note from the folks at Donors Choose saying that from now until then, every dollar donated will be matched by their Board of Directors! This is a great chance to double the amount of money given to children who need to learn science in school. Once all the donations are in, the folks at Donors Choose will take the total amount and divide it by the number of people who donated. You will then receive a gift code via email that will allow you to give that amount to the classroom of your choice. So if the total is $15,000, and 150 people donated, then everyone gets a $100 gift code to donate, no matter how much you personally gave.

If you want more info you can read my original post about the challenge, or just go to the Donors Choose page I’ve set up.

The sidebar of my blog (over on the right) has a widget that says how much we’ve raised here at Bad Astronomy so far (nearly $4000 as I write this, much more than last year [UPDATE (18:30 Mountain time) Holy mackerel! Since I posted this, we're over $5k! Thanks everyone!]). To everyone who has donated and to everyone who will: my very large thanks. And I’m an astronomer, so "very large" to me is vast indeed. And for the kids who get to benefit from it, it’s even bigger.


Scientists are from Mars, the public is from Earth

The American Geophysical Union blog has a link up to a very interesting table, and I feel strongly enough about this topic that I want to share it with you. It’s a list of words scientists use when writing or otherwise communicating science, what the scientists mean when they use that word, and most importantly what the public hears.

[Click to enverbumnate.]

I’ll admit, when I read it I laughed. But then my chuckle dried up when I realized just how dead accurate this is. And the smile pretty much left my face when I read that this table is from an article called "Communicating the Science of Climate Change," by Richard C. J. Somerville and Susan Joy Hassol, from the October 2011 issue of Physics Today.

Yup. I think they have a pretty good point.

My career at the moment could pretty much be called "Science Communicator". I do it here on this blog, I do it on Blastr and in Discover magazine, and when I give talks. Before that (and I guess it’s an occupation that never really leaves you) I was a professional scientist for many years. My training ran deep: 4 years undergrad, 6-7 in grad school, then a decade or so of research after that. I could toss around the phrase "Don’t over-iterate the Lucy-Richardson deconvolution algorithm or else you’ll amplify the noise and get spurious data spikes" with the best of ‘em.

As a science writer, though, I can’t use that! I have to say, "Cleaning up a digital image means using sophisticated mathematical techniques that can sometimes mess the image up and fool you into thinking something’s there that really isn’t."

I hope you can appreciate the difference.

So when I write, I try pretty hard to make the science topic accessible without "dumbing it down". I assume my reader is intelligent, but unfamiliar with the concepts I might be discussing. I try to define words if a reader might not know them, or link to someplace they can get more info if they need it.

But as that table shows, there are plenty of words I use all the time that someone else might know, and think means something else. And this is incredibly important, especially if a science writer — as happens more and more often these days — needs to defuse some sort of political spin thrust upon a topic. A classic example in the wholly-manufactured Climategate "controversy". A lot of hot air was generated over the use of the word "trick" in the stolen emails — which most people interpreted as meaning the scientists did something underhanded and sneaky to hide something important. In reality, we use that word to just mean a method of doing something that’s clever. It’s like saying, "The trick in never losing your car keys is to always hang them on a hook by the door that leads outside." See the difference?

But over that, political battles are won or lost.

There are times I fret over a word in a post. It took me a while to start using the word "denier" instead of "skeptic", for example, but the difference is important. I’ve fought for years to teach people that skepticism is not cynicism or denial; it’s asking for and looking at evidence logically and rationally (in a nutshell). What’s funny is that now the media uses phrases like "climate skeptic" when talking about some people who are not skeptics, in that they are not looking at the evidence logically and rationally. They look at evidence so they can figure out how to spin it, cast doubt in the mind of the public over something that is actually a fact.

That’s why I call it "denial". The word fits, and I intend to continue using it when it does.

I could go on and on.

But here’s the point: communication isn’t simply casting out information from atop a tower. There are two parts to it: presenting an idea to someone, and them understanding it. Sometimes we have to change the way we word things to make that second half happen. Otherwise we’re shouting all the facts in the Universe to an empty room.

Tip o’ the thesaurus to Joanne Manaster.


I am interviewed by the Weinersmiths

Zach Weiner, of Saturday Morning Breakfast Cereal, and Kelly Smith, of Weinersmith, interviewed me for their new podcast, The Weekly Weinersmith. I am actually only their second guest, so we’ll see if the podcast survives.

We talked about the James Webb Space Telescope, mostly, though as usual when I talk to Zach we both revert to 15 year old boys. But only briefly, and only if 15 year old boys paid attention in world history class.

I’ll note I made a mistake in the interview: I said JWST will have 6 mirrors, but it actually has 18. D’oh! I remember very clearly picturing the telescope in my head (it’s hard to do a web search during an interview) and for some dumb reason I was thinking of the old MMT, which I’ll admit is a little bizarre. Heat of the moment, I guess. I wasn’t even within an astronomer’s usual factor of two, so I guess I have to give myself three geek demerits.

I think I made up for it by calling JWST — since its future is uncertain — "Schrödinger’s telescope".

In fact, the stuff I said about JWST deals mostly with its politics and budgetary woes. I’ve written about this before:

- Where will JWST’s money come from?
- The Senate has “saved” JWST? Hang on a sec, folks…
- The watershed moment for JWST
- Hubble’s successor: doomed or saved?
- Congress puts NASA and JWST on the chopping block

So there you go. I’ll note that it’s mostly wondering about JWST’s and NASA’s future until about 45 minutes in, and then we get all optimistic and fun.

Zach and Kelly were great hosts, letting me blather on until I ran out of air. Knowing them both — Kelly’s a scientist, and Zach a hugely devoted science enthusiast and supporter (he’s teaching himself advanced calculus and blogging about it) — this will be a podcast to keep your ear on. Subscribe to it!


Reminder: Donors Choose

Just a quick reminder: I’m participating in a blogger’s challenge with Donors Choose to raise money to get science supplies for classrooms in need. I have added a link in the sidebar of the blog (just below the picture of me) so that you can see how much has been raised, and which also provides a link to the donation page.

If you can’t donate, that’s fine, but if you could, please help spread the word through the social networks; Twitter, Facebook, Google+, whatever you can. This is a great way to get people to contribute directly to kids who need to learn about the joy and wonder of exploring the Universe. Thanks!


Please help kids in need learn about math and science

Exposing people to science, to the wonders of the natural world, is a major theme here on the BA blog. There are so many amazing and interesting things going on in the Universe that sometimes all you really need to do is show them to people, and they’re hooked.

Sometimes, though, they need a little help.

A lot of kids in the US are in desperate need of school supplies to help them learn about math and science. That’s why, once again, I am starting up my Donors Choose page. This is a fantastic group that allows teachers to let people know what things they need and how much it will cost, and then people can donate as much or as little as they want, to the classrooms they want to.

Last year, Bad Astronomy Bloggees — that’s you guys! — donated over $2600 to worthy classrooms. I’d love to be able to raise that much or more this year, too. This is part of a challenge to see which science blogs raise the most money. So if you can, get a smaller cup of coffee, forgo one t-shirt with a snarky message on it, cook one fewer cupcakes, and take that money you saved and send it to some kids who want to learn about the Universe.

I set donation page up to list Math and Science classes with no region specified; they can be from east to west, north to south. But what they all need is a little support.

Here’s my Bad Astronomy Science-a-thon 2011 page.

If you can help, take a look and see which one of the projects clicks with you. This year, the challenge runs from right now through October 22.

I bet a lot of folks reading this right now have a fond memory of a special project, something they did in school that stuck with them into adulthood. I can name ten, personally. So let’s help others have those great memories, too.

Thanks.
