Is Magenta a Real Color?

Most of us are familiar with magenta — it’s a kind of purplish-red that exists between blue and red on color wheels (color wheels don’t accurately represent the physics of photons, but they represent the philosophical reality: color is a human construct that helps us interpret wavelengths to better understand our world).

The odd thing about color vision is that magenta (or pink) color is not in the spectrum of colors, meaning it cannot be generated by a single wavelength of light. Our brains interpret the color sensation of magenta/pink as ‘absence’ of green.

The Importance of Dots

It is often the little things that are the basis of progress… So let me tell you a little story about the tiniest thing on earth: the dot.

Thousands of years ago, a man in his solitude scanned the night sky and saw all those dots shining like so many still fireflies and, perhaps for fun, he decided to join them together to form shapes. This is how zodiac signs and astronomy were born.
Far away, in ancient India, the dot symbolized beauty and the eye of knowledge. But even more, the dot they called “shunya-bindu” represented what we nowadays know as zero. It was first a placeholder and then a fully fledged number, for when it is added to the right of the representation of any given digit, the value of the digit is multiplied by ten. This is how our current numbers and decimal numeration system were born. Continue Reading

Is seeing believing? This book will prove the contrary

I really enjoy communicate the mysteries behind the science of perception in a simple and clear manner with the use of instructive images.

We live in a “reallusive” world… Illusions are not totally unreal, because we feel them as they were real. Reality is also a kind of ‘illusion’. The outside world is mediated through our sense organs: vision, hearing, taste, touch and smell. All what we perceive and feel are just REPRESENTATIONS of reality, not the reality itself.

Children have a different way of looking at the world. So, writing and illustrating optical illusion books for kids is not an easy task, because they are less fooled by visual illusions than adults. This is due to the fact that brain’s capacity to consider the CONTEXT of visual scenes, and not just focus on SINGLE PARTS of scenes, develops very slowly.

My new work “Optical Illusions” will make you question: “is seeing believing?”… The brain is an amazing thing, but it doesn’t always get things right when it comes to sight. My book is here to explain why, with astounding images, baffling puzzles, and simple reveals. Continue Reading
