From the Icosahedron to E8 - Here is a little article I’m writing for the Newsletter of the London Mathematical Society. The regular icosahedron is connected to many ‘exceptional objec...

In the sight of Pharaoh and of his servants, Moses lifted up his staff and struck the water in the Nile, and all the water in the Nile turned into blood. The fish died, and the Nile stank, and... there was blood throughout the land of Egypt.Then things take an unexpected turn.
But the magicians of Egypt did the same by their secret arts.What was the point of that?, I want to ask. (The standard conundrum, where did they get the water?, doesn't seem to bother the biblical author a bit.)
So Pharaoh's heart remained hardened... Pharaoh turned and went into his house, and he did not take even this to heart.
These...acknowledged that they were strangers and exiles on the earth. People who speak thus make it clear that they are seeking a homeland...they desire a better country, that is, a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared for them a city.This sense of longing permeates much Christian spirituality (and rightly so).

I'm not sentimental"It's a rental"... Yes, it's true. The earth is the Lord's and the fulness thereof... human "dominion" just means managing, for a while, something with which I have been entrusted by another. But "it's a rental" can also connote, "I don't have to take good care of it. It doesn't really count".
This skin and bones is a rental
And no one makes it out alive

I am someone with a deep-seated desire to help the planet remain as habitable as possible in the face of the trials humanity is putting it through. I’d like to devote my career to this cause, but am young and haven’t chosen a definitive career path yet. My bachelors is in pure math and I am considering graduate study in either applied math or statistics. I’m curious what you would recommend to someone in my position.Gavin Schmidt from NASA responded on Realclimate.org, and a lively discussion followed. Read it here.
So what is Points of Inflection about, anyhow? It started out with my involvement in the GreenFaith program. I wanted to think in a num...
