### Career Advice: d00d, get a webpage!

 The internet is a series of tubes where you should have a presence in order to promote yourself and your work.
Would you like to increase your profile in the astronomy academic community? Get a webpage. Seriously, if you are anywhere beyond your freshman year studying physics or astronomy with plans of staying in academia, there's no excuse for not having a web presence. Applying to grad school? Get a webpage. About to publish your first paper? Get a webpage and link the paper's arXiv listing.

Looking to live a life of anonymity and unemployment? Stay off the interwebs:

 mahalo.ne.trash does not necessarily support the views of motivateyourself.wordpress.com. But the pictures make us giggle from time to time.
European astronomers, I'm looking right at you. Let's talk one-on-one for a sec. Why do European scientists eschew web presence? I loved your paper and I'd like to know what you look like so I can find you at the upcoming conference. Or I'd like to suggest you for our open postdoc position but I don't know your career stage. Or invite you for a talk and I need your bio. But I can't find you! This is not good for you. I'm sure you have a noble explanation for this phenomenon related to modesty or some such, but the end result is no one can see you or your outstanding work.

Okay, sorry about that. I had to talk to my European friends for a moment. Now that I'm back, here are the basic ingredients of a webpage:

• A short, professional biography. Where'd you start your career and where'd you go after that? What are your research interests and how do you pursue them? Here's a really good example of a concise yet complete web bio by Selma de Mink, who I recently looked up after seeing her light up the Rumor Mill last year.
• A photo. This is optional, I suppose, but handy if you like to meet people at conferences or around campus. Here's Phil Murihead's photo, which shows you what he looks like and provides some nice context of what he works on (instrumentation, Project Minerva). Also, note how he uses very simple HTML to good effect, providing everything you'd need to know about him: NIR and optical instrumentation, Kepler-42 and spectroscopy of M dwarfs. In a similar vein, here's Peter Plavchan's photo and straight-forward yet very effective web page. It's all right there up-front.
• A statement of research interests. Here's Heather Knutson's very professional research page and research summaries. I like this style of general heading followed by a one-paragraph summary. The exercise of coming up with these summaries is handy for helping you remember what exactly you're doing, and just as importantly, how to communicate it concisely to others. Here's Julie Comerford's similarly professional web site, which inspired me to get my web act together 4 years ago.
• If your personal web page contains one thing, make it your CV (but seriously, have more than one thing). Here's Andrew Youdin's CV which is on the long side, but in no way too long. Here's a shorter CV by Phil Hopkins (I'm sure he has a long version given that he publishes ~10 papers/year). And here's the CV of Sara Seager, a highly accomplished astronomer. We should all strive to have our CVs as long as impressive as Sara's! Note what these and other CVs have in common (contact info, educational history, research interests, list of publications and other academic activities). After you publish your first paper (even Nth author) you should create and post your first CV.
• A list of publications. NASA ADS can hook you up with a personal library. Link to that library from your web page. Here's my personal library containing my first-author publications.
• Optional: Nifty simulations! Check out Ben Brown's award-winning simulations of stellar magnetic fields. Full of awes.
• Optional: You in the news. Did you discover Y dwarfs, like Mike Cushing? Of course you didn't (that is, unless you are Davy Kirkpatrick, who needs a better webpage :) ). But maybe you made the news in a similar fashion. Promote it!
Did I forget anything? Sound off in the comments and on the FaceTwitBlags.

Don't forget to update your webpage occasionally, at the very least if you change positions/locations/discover Y dwarfs.

### On the Height of J.J. Barea

Dallas Mavericks point guard J.J. Barea standing between two very tall people (from: Picassa user photoasisphoto).

Congrats to the Dallas Mavericks, who beat the Miami Heat tonight in game six to win the NBA championship.

Okay, with that out of the way, just how tall is the busy-footed Maverick point guard J.J. Barea? He's listed as 6-foot on NBA.com, but no one, not even the sports casters, believes that he can possibly be that tall. He looks like a super-fast Hobbit out there. But could that just be relative scaling, with him standing next to a bunch of extremely tall people? People on Yahoo! Answers think so---I know because I've been Google searching "J.J. Barea Height" for the past 15 minutes.

So I decided to find a photo and settle the issue once and for all.

I started by downloading a stock photo of J.J. from NBA.com, which I then loaded into OpenOffice Draw:

I then used the basketball as my metric. Wikipedia states that an NBA basketball is 29.5 inches in circumfe…

### The Force is strong with this one...

Last night we were reviewing multiplication tables with Owen. The family fired off doublets of numbers and Owen confidently multiplied away. In the middle of the review Owen stopped and said, "I noticed something. 2 times 2 is 4. If you subtract 1 it's 3. That's equal to taking 2 and adding 1, and then taking 2 and subtracting 1, and multiplying. So 1 times 3 is 2 times 2 minus 1."

I have to admit, that I didn't quite get it at first. I asked him to repeat with another number and he did with six: "6 times 6 is 36. 36 minus 1 is 35. That's the same as 6-1 times 6+1, which is 35."

Ummmmm....wait. Huh? Lemme see...oh. OH! WOW! Owen figured out

x^2 - 1 = (x - 1) (x +1)

So $6 \times 8 = 7 \times 7 - 1 = (7-1) (7+1) = 48$. That's actually pretty handy!

You can see it in the image above. Look at the elements perpendicular to the diagonal. There's 48 bracketing 49, 35 bracketing 36, etc... After a bit more thought we…

### The Long Con

Hiding in Plain Sight

ESPN has a series of sports documentaries called 30 For 30. One of my favorites is called Broke which is about how professional athletes often make tens of millions of dollars in their careers yet retire with nothing. One of the major "leaks" turns out to be con artists, who lure athletes into elaborate real estate schemes or business ventures. This naturally raises the question: In a tightly-knit social structure that is a sports team, how can con artists operate so effectively and extensively? The answer is quite simple: very few people taken in by con artists ever tell anyone what happened. Thus, con artists can operate out in the open with little fear of consequences because they are shielded by the collective silence of their victims.
I can empathize with this. I've lost money in two different con schemes. One was when I was in college, and I received a phone call that I had won an all-expenses-paid trip to the Bahamas. All I needed to do was p…
