John Coltrane Draws a Picture Illustrating the Mathematics of Music

Physicist and saxophonist Stephon Alexander has argued in his many public lectures and his book The Jazz of Physics that Albert Einstein and John Coltrane had quite a lot in common. Alexander in particular draws our attention to the so-called “Coltrane circle,” which resembles what any musician will recognize as the “Circle of Fifths,” but incorporates Coltrane’s own innovations. Coltrane gave the drawing to saxophonist and professor Yusef Lateef in 1967, who included it in his seminal text, Repository of Scales and Melodic Patterns. Where Lateef, as he writes in his autobiography, sees Coltrane's music as a "spiritual journey" that "embraced the concerns of a rich tradition of autophysiopsychic music," Alexander sees “the same geometric principle that motivated Einstein’s" quantum theory. Neither description seems out of place. Coltrane was also very much aware of Einstein’s work and liked to talk about it frequently.

What is "Normal"? This Physician's Brilliant Answer Will Make You Stop and Think. In the video below, renowned physician and best-selling author Gabor Maté answers this question by sharing his knowledge and wisdom on this important yet immensely complex issue. In particular, Dr. Maté is pointing out that the concept of “normal” is actually just a myth or an artificial mental construct, while revealing how mental distress and pathology are mainly a consequence of our modern materialistic, consumption-driven, soul-sucking culture. If you appreciate what you read here, consider supporting my work. space_3276808 2. Act normal If you are a high-risk source, avoid saying anything or doing anything after submitting which might promote suspicion. In particular, you should try to stick to your normal routine and behaviour. 3. If you are a high-risk source and the computer you prepared your submission on, or uploaded it from, could subsequently be audited in an investigation, we recommend that you format and dispose of the computer hard drive and any other storage media you used. In particular, hard drives retain data after formatting which may be visible to a digital forensics team and flash media (USB sticks, memory cards and SSD drives) retain data even after a secure erasure. If you do this and are a high-risk source you should make sure there are no traces of the clean-up, since such traces themselves may draw suspicion. 4. If a legal action is brought against you as a result of your submission, there are organisations that may help you.

This Architect Fuses Art and Science by Hand Illustrating the Golden Ratio This Architect Fuses Art and Science by Hand Illustrating the Golden Ratio Rafael Araujo is a Venezuelan architect and illustrator who at the age of fifteen began to observe intelligent patterns in nature, giving rise to his interest in the golden ratio located in our natural environment. More than 40 years later, the results of this hobby is a collection of beautiful illustrations of nature made entirely by hand, equipped with a pencil, a compass, a ruler and a protractor. The artist's illustrations give his ability to represent the mathematical brilliance of the natural world, inciting the reunion of humans with nature. Illustrations that seem to come from a technological team, are made entirely by hand, mixing mathematical perfection with the artistic performance of Araujo. Through the application of growth patterns governed by golden ratio's geometric formulas, the secrets of carefully detailed designs of natural spirals, sequences and proportions unfolds.
