Optical illusions are fun, but they can also teach us a lot about how our brains work. In particular, how our brains accomplish the incredible feat of constructing a three-dimensional reality using nothing but 2-D images from our eyes. A...

Bright pillars of light... clouds of glowing dust... shimmering discs floating around the sun... signs of extraterrestrial activity, or is there a more rational and scientific explanation for this phenomenon?

When it comes to sex things can be complicated, but for the three species we are looking at today, sex is really hard.

Only 1% can spot these hidden numbers—are your eyes sharp enough?

Let's talk about the famous "the impossible triangle" illusion and how it works. There are many interesting examples and drawings that are based on this illusion, we can mention them as well.

DIY SCI host Steve Spangler demonstrates how you can make a simple optical illusion using two pieces of cardboard!

This motion of Cardano's Hypocycloid mechanical model was described first by Nicolaus Copernicus. Consider two circles of radii R and R/2 with the smaller one rolling inside the bigger circle without slipping. Copernicus' Theorem...

The fake puddles of water that we see on the road on a sunny day is due to an optical phenomenon called a mirage, which is caused by the refraction (or bending) of light rays due to different temperatures of the air above the road. On a...

The beard appears as dots of color when it first begins growing back because each hair is still tiny and short. When the stubble has just begun to sprout, the young facial hair emerges as small black or brown dots on fair skin. Seen from...

At high speeds, wheels may appear to be turning backwards, creating an optical illusion known as the Wagon wheel effect. This happens because our brains fill in gaps between images to create the illusion of continuous movement. As a...

Dive into the viral sensation of the color-changing dress that puzzled the world, as we explore the science behind visual perception and illusions. Discover how lighting, context, and individual differences in visual processing...
