Rule 1 of Writing: Try Not to Sound Like a Doofus

Via somebody on Twitter, Copyblogger has a post titled “7 Bad Writing Habits You Learned in School,” which is, as you might guess, dedicated to provocatively contrarian advice about how to write, boldly challenging the received wisdom of English faculty: What is good writing? Ask an English teacher, and they’ll tell you good writing is… Continue reading Rule 1 of Writing: Try Not to Sound Like a Doofus

Lectures Are a Small Part of Learning

FriendFeed and Twitter are a terrific source of articles about how New Media technologies are Changing Everything. The latest example is Sebastian Paquet’s The Fate of the Incompetent Teacher in the YouTube Era, in which he declares that the recorded lectures of Salman Khan are the beginning of the end for bad teachers: Even assuming,… Continue reading Lectures Are a Small Part of Learning

Communicating Science in the 21st Century

My panel on “Communicating Science in the 21st Century” was last night at the Quantum to Cosmos Festival at the Perimeter Institute. I haven’t watched the video yet– Canadian telecommunications technology hates me, and I’m lucky to get a wireless connection to stay up for more than ten minutes– but if the video feeds I’ve… Continue reading Communicating Science in the 21st Century

The experience has me thinking a bit about what we’re doing here, and talking to people in other departments, and it seems like a good question for my wise and worldly readers. At the… Continue reading Academic Poll: How Much Should Students Write?

A Brief History of Timekeeping

I gave a guest lecture this morning in a colleague’s sophomore seminar class about time. She’s having them look at time from a variety of perspectives, and they just finished reading Longitude, so she asked me to talk about the physics of clocks and the measurement of time. I’ve long considered using “A Brief History… Continue reading A Brief History of Timekeeping

Adventures in OA

The abbreviation here has a double meaning– both “Open Access” and “Operator Algebra.” In my Quantum Optics class yesterday, I was talking about how to describe “coherent states” in the photon number state formalism. Coherent states are the best quantum description of a classical light field– something like a laser, which behaves very much as… Continue reading Adventures in OA
