Batman Equation - Numberphile




It's fun that it's not just an approximation, it's a perfect Batman logo. If you put in on an issue of Batman, nobody would remark on it.

On Quora somebody asked who wrote it, and this answer came:

I wrote it many, many years ago. I was teaching at a few art schools throughout the greater Sacramento area, and I used it to engage my students in the topic of graphing.  One of my coolest students (Mr. Wilkinson aka i_luv_ur_mom) posted it to Reddit back in 2011 and it went viral.  These days, I'm a full time professor over at American River College, doing every thing I can to make math as enjoyable as possible.

Great Olympus offers

If you have considered the Micro Four Thirds system (and you really should, compact and top quality), then right now there are two amazing Olympus offers of next-newest models with kit lens:

The compact workhorse:
Olympus E-PL6
For only $269

And the amazing:
Olympus OM-D E-M5
for just $499

Both are dirt-cheap ways of getting a really good camera with standard zoom lens, and near-endless possibilities for expansion later with fancy lenses and such. And unlike five years ago, now speed and image quality is fully competitive with the big, heavy Canons and Nikons.
