Blue-green, orange-pink, yellow-orange, violet-pink - these are some of the colors it's hard to agree on. Why is that? Because our perceptions are subjective.
They depend on our position, the angle of perception, interference, the quality of the light source and, above all, the sensitivity of our receptors.
Not only does the proportion of cones and rods in the back of our eyes vary from one individual to another, but so do their length, sensitivity, number and the distribution of cones between the colors blue, green and red. In other words, nobody sees exactly the same color as another person. Nor do color-blind people perceive the same colors as other color-blind people.
In short, to find out, the Color Controversy website suggests testing your color judgment to arrive at a collective color congruence. For some, this is a long way off!

Flying without a motor, inspired by birds
Would it be possible to fly without a motor? The first human tests that tried to imitate birds were unsuccessful. However, nowadays, researchers are analyzing the gliding flight of large species, such as the albatross and its gradient flight. Small gliders are already able to reach incredible speeds with this technique. What if, one day, the dream of perpetual flight came true?
The rise of robotics, constantly enhanced by artificial intelligence, raises questions about the future of humanity. In view of the socio-professional stakes involved, we need to ask ourselves some essential questions to prevent society from drifting off course, inundated by these technological innovations.
We've developed a safe, even sanitized world. Wouldn't it be a good idea to restore a certain amount of risk, including in living environments such as schools? But parents and principals alike must be prepared to accept the return of risky play to the playground.
