Scott Adams, man of the perfect comparison

A friend recently shared with me the link to Scott Adams’ (of Dilbert fame) blog post discussing regaining his voice after 18 months being unable to converse in a normal tone.  Recently, Scott posted another article which included a comment about all the traffic and feedback he’s gotten on that article.  Going from 25,000 hits a day to around 180,000 hits a day had a profound effect on him.  So profound, in fact, that he made one of the best quotes ever on how this reaction has affected him.

I am more touched than a congressional page.

That’s quality writing you just won’t get from the big networks.

Tetrahedron rotation symmetry group

No, I don’t actually know what it means. Yes, I have the words to accompany it. No, they don’t help me understand it. Yes, I understand the words individually. No, I don’t comprehend the words in the sentences given. Yes, I posted this because it’s shiny.

250px-Tetrahedral_group_2.svg.png Symmetry is a foundational concept in several sub-disciplines of mathematics, particularly geometry and abstract algebra. The rotation symmetry group of the tetrahedron (shown here) associates the 12 different orientations of a tetrahedron with two kinds of spatial rotation that rearrange those orientations: a 120° rotation around each of the 4 vertices (reddish arrows), and 180° rotation through opposite edges (blue arrows). Diagrams illustrating the symmetries of a mathematical object in this format are called cycle graphs.

Oh, and yes – it is something I picked up from Wikipedia – possibly the greatest resource in the known universe.
