Other Writings

This page collects some of my non-research writings from here and there; for a more complete listing see my CV. See also my videos.

From Eternity to Here

I’ve written a popular-level book about cosmology and the arrow of time — From Eternity to Here: The Quest for the Ultimate Theory of Time, published in January 2010. It’s listed on amazon.com. So what are you waiting for?


Like all contemporary deep thinkers, I’ve taken up blogging as a way to share my free-ranging wisdom with the breathlessly waiting world. Since July 2005 I’ve been a member of the group blog Cosmic Variance; before that, starting in February 2004, I had been blogging solo at Preposterous Universe.

General Relativity Notes

The most useful thing here would be the Lecture Notes on General Relativity. These are the record of a graduate course I taught in 1996, Physics 8.962 at MIT. If you are impatient and want the condensed version, here is a tiny introduction to general relativity (24 pages available as PDF). If on the other hand you are more ambitious and want a revised and expanded version, you can buy the textbook, Spacetime and Geometry: An Introduction to General Relativity, published by Addison-Wesley.

Cosmology Primer

I wrote a cosmology primer for the Kavli Institute for Cosmological Physics. It covers the basic features of contemporary cosmology at an accessible level.


I’ve inflicted my opinions about the cosmology, dark energy, and the preposterous universe on an unsuspecting public in a variety of venues.

On the off chance that there is an interesting topic that I haven’t written a review about, I keep a page of interesting reviews by other people.

Other writings

But I can’t be confined to just reviewing stuff. Here are some other scribblings:
