Your awesome Tagline
I don’t give a shit what the world thinks. I was born a bitch, I was born a painter, I was born fucked. But I was happy in my way. You did not understand what I am. I am love. I am pleasure, I am essence, I am an idiot, I am an alcoholic, I am tenacious. I am; simply I am…You are a shit.

Why is group theory important?
SYMMETRY, motherfuckers!
The mathematics of public-key cryptography uses a lot of group theory. Different cryptosystems use different groups, such as the group of units in modular arithmetic and the group of rational points on elliptic curves over a finite field. This use of group theory derives not from the “symmetry” perspective, but from the efficiency or difficulty of carrying out certain computations in the groups. Other public-key cryptosystems use other algebraic structures, such as lattices.
Identification numbers are all around us, such as the ISBN number for a book, the VIN (Vehicle Identification Number) for your car, or the bar code on a UPS package. What makes them useful is their check digit, which helps catch errors when communicating the identification number over the phone or the internet or with a scanner. The different recipes for constructing a check digit from another string of numbers are based on group theory. Usually the group theory is trivial, just addition or multiplication in modular arithmetic. However, a more clever useof other groups leads to a check-digit construction which catches more of the most common types of communication errors. The key idea is to use a noncommutative group.
On the lighter side, there are applications of group theory to puzzles, such as the 15-puzzle and Rubik’s Cube. Group theory provides the conceptual framework for solving such puzzles. To be fair, you can learn an algorithm for solving Rubik’s cube without knowing group theory (consider this 7-year old cubist), just as you can learn how to drive a car without knowing automotive mechanics. Of course, if you want to understand how a car works then you need to know what is really going on under the hood. Group theory (symmetric groups, conjugations, commutators, and semi-direct products) is what you find under the hood of Rubik’s cube.

Algarve, Portugal (by Fragga)
In 1915, in Geneva, I avidly read Crime and Punishment in the very readable version by Constance Garnett. That novel, whose heroes are a murderer and a prostitute, seemed to me no less atrocious than the war that surrounded us. I imagined at the time that Dostoyevsky was a kind of great unfathomable God, capable of understanding and justifying all beings. I was astonished that he had occasionally descended to mere politics, that he discriminated and condemned.
To read a book by Dostoyevsky is to penetrate a great city unknown to us, or the shadow of a battle. Crime and Punishment revealed to me, among other things, a world different from my own. When I read Demons, something very strange occurred. I felt that I had returned home. The steppes were a magnification of the pampas. Varvara Petrovna and Stepan Trofimovich Verkhovensky were, despite their unwieldy names, old irresponsible Argentines. The book began with joy, as if the narrator did not know its tragic end.
In the preface to an anthology of Russian literature, Vladimir Nabokov stated that he had not found a single page of Dostoyevsky worthy of inclusion. This ought to mean that Dostoyevsky should not be judged by each page but rather by the total of all the pages that comprise the book.

Perhaps you’ve heard the news that Yahoo! has bought Tumblr. Rumors about the deal started swirling last week, on the night of Thursday, 5/16, and the deal was officially announced on Monday, 5/20.
Just 300 posts were shared on Tumblr about the rumor on Thursday. On Friday it was up to 1,216 posts, and by Sunday there were more 14,300 posts generating 757k reblogs and 420k likes! Over the past few days, more than 29,600 posts about Tumblr + Yahoo! were reblogged 2.5 million times by more than 1 million people.
The top post about the news is from ruinedchildhood and has generated 88,500 total notes, including more than 55,600 reblogs! Check out that reblog tree; more than 29,400 reblogs are more than 9 degrees removed from the original post.
And Yahoo! CEO Marissa Mayer’s announcement about the deal has received 5,578 reblogs and 4,387 notes so far (and that’s still climbing).
It’s been a big few days for Yahoo! and Tumblr. We’re tracking the whole Tumblr conversation about the news, so we’ll keep you posted on any interesting stats as things progress.

St James’s Park, London, in April (mine) The gardens here make you want to fall about and squeal with glee. Actually all English gardens, which are the best gardens in the world, make me feel that way.
