math blogosphereFrom time to time, I’ve done something that could be construed as blogging for years now (at my web site,, but I am still a blogosphere novice.

As far as I understand, it is good blogging etiquette, not to mention a service to your readers, to have a blogroll–links to blogs that one likes, or that one follows anyway, or that one recommends that others read even if he has no intention of doing so, sort of like Netflix’s “if you liked A, you’ll also like B.”

So while our blogging platform doesn’t have a “blogroll” feature yet (we just started!), I’ll just mention some of my favorite blogs in this brief post. Some of these are blogs I find invaluable and read as often as I can; others are just fun to check out once in a while.

Anyone has great math or physics blogs to recommend? Please feel free to do so by leaving a comment below.
