This post is mostly brought to you by my very nerdy girlfriend. She loves Brown Sharpie and I do urge you to check it out, at least if you know something about math. I found these a lot of fun, even if I didn't get all the mathematical implications:
Sigma Freud: functional analysis
Sigma Freud: motivational speaking
Sigma Freud: couples therapy
One of my new favorites, Abstruse Goose, shows us what exactly happens in our brains during the average phone conversation. Awe-inspiring or kind of disturbing? I'm not sure. Probably both.
Meanwhile, xkcd continues to make graphs about topics that are too often ignored by science.
Frequency with which various adjectives are intensified with obscenities. It's also good to include some unusual words, like peristeronic. On the other hand, if you have to define them, maybe the answer is obvious. At least I learned another new word through xkcd.
Last but definitely not least, if you're a fan of Charles Babbage and Ada Lovelace's work, do check out 2-D Goggles. The ongoing saga of Lovelace and Babbage vs. the Organist has reached episode 7. In reality, Babbage was an avid hater of street musicians. He even had a chapter in his autobiography called "Street Nuisances". You can read more on that here. The comic's depiction of him as a crazy-eyed organist hater who's trying to end all music as if it's a battle of good and evil - is really pretty close to the truth, if you read his book. What I love about this comic is that it makes superheroes out of math geniuses. It's also damn funny.
