I met a traveller from an antique land
Who said: Two vast and trunkless legs of stone
Stand in the desert. Near them on the sand,
Half sunk, a shatter'd visage lies, whose frown
And wrinkled lip and sneer of cold command
Tell that its sculptor well those passions read
Which yet survive, stamp'd on these lifeless things,
The hand that mock'd them and the heart that fed.
And on the pedestal these words appear:
"My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!"
Nothing beside remains: round the decay
Of that colossal wreck, boundless and bare,
The lone and level sands stretch far away.
--Percy Bysshe Shelley, "Ozymandias"

Foolish consistency is the hobgoblin of little minds.
-- Ralph Waldo Emerson, "Self-Reliance"

I have just three things to teach:
simplicity, patience, compassion.
These three are your greatest treasures.
Simple in actions and in thoughts,
you return to the source of being.
Patient with both friends and enemies,
you accord with the way things are.
Compassionate toward yourself,
you reconcile all beings in the world.

-- Lao Tzu, "Tao Te Ching"

Research

I study astrophysics, space physics, and astrobiology, particularly the effects of "extraplanetary" radiation, such as cosmic rays, X-rays, and gamma-rays, on planetary habitability and manned space missions. I've also worked on the physics of the solar wind and how it interacts with planetary atmospheres and the interstellar medium.
