Fire and Ice: Starting Up the Snowball

I attended a talk last week by Francis Macdonald, discussing his work on Snowball Earth geology. He touched on the "Fire and Ice" hypothesis for the initiation of the Snowball, and I thought I would interpret it in ballad form. Needs a little work and maybe another verse, so feel free to critique. 

In late Proterozoic times 

the Earth was calm and warm

A billion peaceful years since the

Self-defense

Well, that was a somewhat protracted hiatus. I think my muse was in hibernation. In any case, she rose to the occasion when I defended my Ph.D. a couple of weeks ago, and here's how I summed up my talk: 

“Measured and modeled albedos of sea-ice surfaces on the oceans of Snowball Earth”

A planet orbits round a yellow sun

Light years away or megayears ago

Its seas are dark, its continent is dun

But brilliant sea ice sets its pole aglow

Its CO2…

Photons plus Atmosphere equals Awesomeness

Sorry I haven't posted for a while. My muse sort of went into hibernation for a bit after my general exam. Actually, I suppose this particular blog would be a collaboration between muses, if we're going with the classical categorizations: Euterpe (lyric poetry), Urania (astronomy), and sometimes Thalia (comedy.)

Anyway, here's a sonnet inspired by the Radiative Transfer (that is, the interaction of sunlight and infrared radiation with the atmosphere) course I'm taking this…

Notes from a Defense

I wrote this while my friend and colleague Marcela Ewert presented her work at her Ph.D. defense. She's been doing a lot of really cool work about how Arctic microbes make their living despite the temperature and salinity extremes found in the sea ice and in the snow that rests on it. Here's a link to some of the work included in her dissertation.

Jargon note: exopolysaccharides, also known as…

Drake Made A Little List

Here's a little something about the Drake Equation, based on the song "I've Got a Little List" from Gilbert and Sullivan's "The Mikado" (here's a rather good modern take on it by Opera Australia.)

To answer those who ask why there's no aliens around

I've got a little list

I've got a little list

Of factors that when multiplied say whether they're not…

Sing a Song of Spaceflight

I've been working on lyrics to a Gilbert and Sullivan pastiche about the Drake Equation, but it's going a bit slowly. In the meantime, here is my version of "Wild Rover", which I sang at our local Chantey Sing a while back (the Chantey Sing is a get-together where people take turns leading the group in singing old sailors' work songs and other nautical music.) As I explained to the folks there, these days the exploration of unknown…

Tiny Submarine

As you may know, the oceans of Europa are sequestered underneath a layer of ice which is probably ten or twenty kilometers thick. This makes them a little tricky to access, especially given the limited resources available to a logistically-feasible lander. So I was intrigued by this article about a highly miniaturized submersible vehicle that wouldn't require much energy to transport…

Scatter, Adapt and Remember

Last month I went to see a talk by Annalee Newitz of io9.com about her new book, Scatter, Adapt and Remember. In the talk, she went over some of Earth's previous mass extinctions and their notable survivors, and discussed how humanity might manage to make it through the next one, whatever its cause might be.



It was an excellent talk and it inspired me to write the…

Writing a research paper is a challenging task full of challenges. The process is involving, time-consuming and requires knowledge of several skills. The following tips are, however, essential to help students deliver maximally on their project.

 Consider working in a group: forming a dissertation group may be an important approach to work on a thesis. A research project is an involving and sometimes working on it alone may be discouraging and boring. This may lead to procrastination…
