Langton's Ant

Langton's Ant
A 4-state two-dimensional Turing machine invented in the 1980s. The ant starts out on a grid containing black and white cells, and then follows the following set of rules. 1. If the ant is on a black square, it turns right and moves forward one unit. 2. 3. When the ant is started on an empty grid, it eventually builds a "highway" that is a series of 104 steps that repeat indefinitely, each time displacing the ant two pixels vertically and horizontally. (right figure) steps.

The Infinity Room With this immersive installation, French artist Serge Salat invites visitors to take a journey through endless layers of space, decked out with cubic shapes, panels of mirrors, shifting lights and music. “Beyond Infinity” is a multi-sensory, multimedia experience that blends Eastern Chinese with Western Renaissance. Inspired by the Suzhou Gardens, a masterpiece of Chinese landscape, the three-lined trigram of I Ching is the main pattern that organizes the space of the work. Salat uses mirrors as optical illusions, exploding a single room into spatial infinity. via [Architizer] Views: 422998 Tags: Serge Salat, The Infinity Room, architecture, design

turing.pdf The Sacred Geometry Of Music The Sacred Geometry Of Music by Andrew Lorimer Music uses the laws of vibration to manifest aurally what exists at the center of everything. Into our reality springs a non-visual harmonic law that is universal. The notes and intervals of music speak directly to the chakra centers and causes them to vibrate in harmony to the vibration of a string or vocal chords, speakers moving through the air, or the sound of someone’s lips making a farting noise through a metal tube. Music uses the laws of physics and mathematics to bring out an emotional response in the listener. Clock Harmonisphere The mathematics of the harmonisphere are amazing. When we measure the same chords on the harmonisphere, the seven chords have the same mirrored combinations as the piano:

Huge Model of Isengard From Over 22000 LEGOs Master LEGO building team OneLUG have completed their incredible model of the Battle of Isengard, a key battle in The Lord of the Rings: The Two Towers. The model includes a whopping seven-foot tall Orthanc tower, dozens of ents, over a hundred orcs, and two small hobbits. Built to minifig scale, the entire tableau weighs 145 pounds, and uses 22,000 LEGO bricks across its eight-foot diameter. We’ve seen some pretty incredible LEGO creations inspired by J.R.R. Tolkein, but this one takes the cake. Incredibly, key scenes from the Lord of the Rings film are depicted in exacting detail across the diorama. (OneLUG via io9, The Brothers Brick)

La complexité du vivant expliquée simplement La société humaine est le premier organisme vivant qui se soit affranchi de la matière pour se complexifier. Elle utilise un liant virtuel, (la culture) dont les mutations sont instantanées, permanentes, innombrables et les variations infinies. Cette forme d’évolution totalement nouvelle est ultra rapide : Elle est aussi cumulative et exponentielle, mais l’explosion qui en résulte s’observe non plus sur des milliards d’années mais sur quelques millénaires dont il est fort probable que nous vivons le dernier ! Il est vrai que nous ne percevons encore que depuis quelques décennies les premiers soubresauts de cette terrible force explosive. Pour avoir une idée des échelles de temps, je vous propose de ramener l’age de la terre à une durée de 24 heures : Une folle journée dont j’ai scanné la belle illustration sur « science et vie junior » que je remercie: C’est avec cette perspective qu’il faut comprendre l’évolution de la société humaine. Essayons de l’évaluer : Protégés par qui ?

Thinking Unconventionally A Letter from a College Professor Some time ago I received a call from a colleague, who asked if I would be the referee on the grading of an examination question. He was about to give a student a zero for his answer to a physics question, while the student claimed he should receive a perfect score and would if the system were not set up against the student. The instructor and the student agreed to an impartial arbiter, and I was selected. The student had answered: "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. I pointed out that the student really had a strong case for full credit since he had really answered the question completely and correctly. I gave the student six minutes to answer the question with the warning that the answer should show some knowledge of physics. "Take the barometer to the top of the building and lean over the edge of the roof. "Well," said the student.

Collected Quotes from Albert Einstein [Note: This list of Einstein quotes was being forwarded around the Internet in e-mail, so I decided to put it on my web page. I'm afraid I can't vouch for its authenticity, tell you where it came from, who compiled the list, who Kevin Harris is, or anything like that. Still, the quotes are interesting and enlightening.] "Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius -- and a lot of courage -- to move in the opposite direction." Copyright: Kevin Harris 1995 (may be freely distributed with this acknowledgement)
