Keck time!

It's been a little while since I've posted here because I was busy last week preparing for my first solo night on the Keck 1 Telescope. The twin Keck telescopes are the largest visible light telescopes in the world, with a diameter of 10 meters. I've spent about a dozen nights at Keck as a graduate student observing with my advisor, Geoff Marcy, and/or various collaborators. But last night was the first time Dad gave me the keys to the Corvette--and I didn't even have a curfew!

Sunday morning, Erin and Owen dropped me off at Honolulu airport and I caught an Aloha flight over to The Big Island (that's its actual name!). The flight took 45 minutes and I drove a rental car another 45 minutes from Kona International Airport to Keck HQ in Waimea. One of the great things about observing at Keck is that you can observe from sea level instead of having to spend the night at 14,000 feet where the actual telescope is. It may sound a little silly, but yes, I traveled an hour and a half to use a telescope remotely. Astronomy!

Below are are pictures of 1) The telescopes at 14,000 feet atop the ex-volcano Mauna Kea 2) Keck HQ in sleep Waimea and 3) your's truly hanging out in the control room, wearing a T-shirt and shorts.





I was using the telescope to search for planets around nearby stars. Here's how a typical planet hunting night goes: I tell the telescope operator what star to got to. The operator (TO or OA) is on the mountain gasping for oxygen and pictured on the TV screen above and to the left of me, and we communicate using the Polycom unit next to the TV. The TO points the telescope to the star and I click a button that says "expose." I get 4 monitors plus my laptop to push a button over and over. Science!

Actually, the information on those monitors is very important, conveying information about the status of the various instrument components, telescope and target star, as well as planning tools, weather information and other useful software. Oh, and don't forget the clock. Yes, that's 4:11 AM in the picture. I had recently pushed past the 2 AM barrier and had caught my second wind. I used a relatively long 3 minute exposure to set up my camera in timer mode to snap this picture.

Thanks to clear skies, low humidity, sub-arcsecond seeing and a highly skilled TO, I was able to observe 195 stars last night, making my first solo Keck run successful beyond what I could have hoped for. In fact, I was moving through my target list so fast that I had to add some fainter stars to my list so I could do things like run to the restroom and get food!

I get to repeat this again Saturday when I go back to Keck to observe for another project, this time for my collaborator Josh Winn and our Rossiter project.

195 stars!? Thats incredible. Do you fly home before going to sleep if you've only got one night or do you stay there?

Looking at the Rossiter Project link, I wished I had taken more math in college. Amazing stuff you are into John et.al.!

An annual note to all the (NSF) haters

It's that time of year again: students have recently been notified about whether they received the prestigious NSF Graduate Student Research Fellowship. Known in the STEM community as "The NSF," the fellowship provides a student with three years of graduate school tuition and stipend, with the latter typically 5-10% above the standard institutional support for first- and second-year students. It's a sweet deal, and a real accellerant for young students to get their research career humming along smoothly because they don't need to restrict themselves to only advisors who have funding: the students fund themselves!
This is also the time of year that many a white dude executes what I call the "academic soccer flop." It looks kinda like this:


It typically sounds like this: "Congrats! Of course it's easier for you to win the NSF because you're, you know, the right demographic." Or worse: "She only won because she's Hispanic."…

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…

Culture: Made Fresh Daily

There are two inspirations for this essay worth noting. The first is an impromptu talk I gave to the board of trustees at Thatcher School while I was visiting in October as an Anacapa Fellow. Spending time on this remarkable campus interacting with the students, faculty and staff helped solidify my notions about how culture can be intentionally created. The second source is Beam Times and Lifetimes by Sharon Tarweek, an in-depth exploration of the culture of particle physics told by an anthropologist embedded at SLAC for two decades. It's a fascinating look at the strange practices and norms that scientists take for granted.
One of the stories that scientists tell themselves, whether implicitly or explicitly, is that science exists outside of and independent of society. A corollary of this notion is that if a scientific subfield has a culture, e.g. the culture of astronomy vs. the culture of chemistry, that culture is essential rather than constructed. That is to say, scientific c…
