For a physicist, Penrose spent way too much time drawing cool stuff.

A Penrose tiling has many remarkable properties, most notably:

* It is nonperiodic, which means that it lacks any translational symmetry. More informally, a shifted copy will never match the original exactly.
* Any finite region in a tiling appears infinitely many times in that tiling and, in fact, in any other tiling. This property would be trivially true of a tiling with translational symmetry but is non-trivial when applied to the non-periodic Penrose tilings.
* It is a quasicrystal: implemented as a physical structure a Penrose tiling will produce Bragg diffraction; the diffractogram reveals both the underlying fivefold symmetry and the long range order. This order reflects the fact that the tilings are organized, not through translational symmetry, but rather through a process sometimes called “deflation” or “inflation.”

Started at 10am one day and ended at around 1 the next.
So about 27 hours.
FUN!

Gonna be lighter than this when I wash it off.
Side note, I love Wadio.

I am no prophet—and here’s no great matter;
I have seen the moment of my greatness flicker,
And I have seen the eternal Footman hold my coat, and snicker,
And in short, I was afraid.

Sorry, I cannot get enough of this poem

I want to watch this again…

When Catherine wants to do something and…
to the extent it won’t hurt anyone, and she’s not always right…
she does it for pleasure and to learn something from it.
She hopes to attain wisdom that way.

let the right one in

Let us do something while we have the chance! It is not every day that we are needed. Not indeed that we personally are needed. Others would meet the case equally well, if not better. To all mankind they were addressed, those cries for help still ringing in our ears! But at this place, at this moment of time, all mankind is us, whether we like it or not. Let us make the most of it, before it is too late! Let us represent worthily for once the foul brood to which a cruel fate consigned us!
