Synesthesia, Savant Syndrome: Jason Padgett, A Real ‘Beautiful Mind'

Brain-damaged college dropout became maths genius after attack | Mail Online

A college dropout has been hailed a unique maths genius - after his brain was damaged in a brutal attack by muggers.

Jason Padgett, 41, was left concussed after he was ambushed outside a karaoke club and repeatedly kicked in the head.

Now, wherever he looks, he sees mathematical formulas and turns them into stunning, intricate diagrams he can draw by hand.

He is the only person in the world known to have the skill and experts say it was caused by his head injury.

“I see bits and pieces of the Pythagorean theorem everywhere,” he said. “Every single little curve, every single spiral, every tree is part of that equation.”
The diagrams he draws are called fractals and Padgett can draw a visual representation of the formula Pi, that infinite number that begins with 3.14.

A scan of Padgett’s brain showed damage that was forcing his brain to overcompensate in certain areas that most people don’t have access to, Brogaard explained. The result was Padgett was now an acquired savant, meaning brilliant in a specific area.

“Savant syndrome is the development of a particular skill, that can be mathematical, spatial, or autistic, that develop to an extreme degree that sort of makes a person super human,” Brogaard said.

This is a hand drawn fractal. Jason Padgett, a mathematician with synesthesia (a condition where the brain interprets numbers as shapes) draws a fractal of space time at the Planck Particle size frame and at a certain frequency. Then wave equations (uncertainty) make the drawing warp and stretch as space time does from the Heisenburg Uncertainty Principle.

Möbius Objects and Animations


Möbius strip - Wikipedia, the free encyclopedia



The Möbius strip or Möbius band (pronounced UK: /ˈmɜːbiəs/ or US: /ˈmoʊbiəs/ in English, [ˈmøːbi̯ʊs] in German) (alternatively written Mobius or Moebius in English) is a surface with only one side and only one boundary component. The Möbius strip has the mathematical property of being non-orientable. It can be realized as a ruled surface. It was discovered independently by the German mathematicians August Ferdinand Möbius and Johann Benedict Listing in 1858.[1][2][3]

The Möbius Gear


[...]
One can think of the black portion in the image as the ring with a fixed zero input velocity. A single blue gear is a planet, and the white strip is the sun. Output can be taken either from the sun or the planets (with no regard for practicality!). In practice, however, it’s easiest to actuate the Möbius strip (the white portion).
[...]
The end result is a functional prototype, but rotating the middle ring without having the blue gears pop out is a little tricky. If you’re so inclined you can download a description of the entire process from modeling to fabrication.

Universal Property of Music Discovered

Cognitive universal for scales : Compute Scotland


Researchers at the Institute for Logic, Language and Computation (ILLC) of the University of Amsterdam have discovered a universal property of scales: if their tones are compared in a two- or three-dimensional way by means of a coordinate system, they form convex or star-convex structures.

 


By placing scales in a coordinate system (‘Euler lattice’) they can be studied as multi-dimensional objects.

Dr Aline Honingh (left) and Prof. Rens Bod (right) from the ILLC did this for nearly 1,000 scales from all over the world, from Japan to Indonesia and from China to Greece.

1000 scales

By placing scales in a coordinate system (an ‘Euler lattice’) they can be studied as multidimensional objects. Dr. Aline Honingh and Prof. Rens Bod from the ILLC did this for nearly 1,000 scales from all over the world, from Japan to Indonesia and from China to Greece. To their surprise, they discovered that all traditional scales produced star-convex patterns. This was also the case with almost 97% of non-traditional, scales conceived by contemporary composers, even though contemporary composers often state they have designed unconventional scales. This percentage is very high, because the probability that a random series of notes will produce a star-convex pattern is very small. Honingh and Bod try to explain this phenomenon by using the notion of consonance (harmony of sounds). They connect their research results with language and visual perception where convex patterns have also been detected, possibly indicating a cognitive universal (a general cognitive property).

First Aperiodic Tiling With A Single Shape
Mathematicians discover how to tile a plane in a nonrepeating pattern using a single shape.
Today, Joshua Socolar and Joan Taylor at Duke University announce that they have solved the einstein problem and in the process they've discovered an entirely new way to approach the problem.
"The tile presented here is the only known example of an aperiodic tile," they say.

The Mandelbulb a 3D Mandelbrot Set

Fractal
A fractal is "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,"[1] a property called self-similarity.

The Mandelbrot set is a famous example of a fractal

The Real 3D Mandelbulb

It's found by following a relatively simple math formula. But in the end, it's still only 2D and flat - there's no depth, shadows, perspective, or light sourcing. What we have featured in this article is a potential 3D version of the same fractal.

Resulting renders

But it wasn't until I incorporated proper shadowing that the subtleties of this incredible object became apparent. For the renders below and exploration afterwards,

Robert J. Lang

Dr. Robert J. Lang 1961 (age 47–48) is an American physicist who is also one of the foremost origami artists and theorists in the world. He is known for his complex and elegant designs, most notably of insects and animals. He has long been a student of the mathematics of origami and of using computers to study the theories behind origami. He has made great advances in making real-world applications of origami to engineering problems.

Like a musical composer, the origami artist works with patterns and relationships within the paper and arranges those patterns into something that touches a human aesthetic. And while complex figures must be designed according to fixed, fundamental principles (design), there is always some spark of sponteneity and serendipity (creation) in the realization.

The intersections between origami, mathematics, and science occur at many levels and include many fields of the latter. We can group these intersections into roughly three categories:

  • Origami mathematics, which includes the mathematics
    that describes the underlying laws of origami;

  • Computational origami, which comprises algorithms
    and theory devoted to the solution of origami problems by mathematical
    means;

  • Origami technology, which is the application of
    origami (and folding in general) to the solution of problems arising
    in engineering, industrial design, and technology in general.
