We all come to believe that a textbook or encyclopedia is 100% reliable, and we will never find misleading or misleading information in these publications. However, not even science itself can guarantee us absolute certainty about something.

With that in mind, today we have prepared for you a list of some of the illustrations we are tired of seeing published around that may not be completely correct or give us a little confusing idea about the actual product they represent. Check out the list!

1 – Atom model

This classic planetary model was proposed by Rutheford in 1911. It has been printed in millions of textbooks around the world. However, even with modern electron microscopes , being so small, it is still impossible to see what a single atom actually consists of. Thus, the fact that electrons move around the nucleus, like the planets around the sun, is just a guess. Moreover, the appearance of electrons is completely unknown to us.

2 – DNA molecule

DNA molecules do not exactly follow the patterns seen in textbooks. The purpose of the image created in the books is not to show the DNA molecule but to give you an idea of ​​the basics of your work using such a model. In fact, DNA doesn’t look so colorful.

3 – World Map

Another item to watch out for is the world maps. Transferring something three-dimensional like Earth to a flat image is quite complicated. Any map, whether of the world, a country or any other location, is just a projection. One of the most famous projections is the world map created by Gerardo Mercator.

4 – Solar system scheme

Securely transmitting certain distances is quite difficult. Therefore, we should not assume that the solar system representation scheme reflects all scales 100% faithfully. Spatial distances are very hard to imagine. The planets in our Solar System are actually very far apart.

The scheme where they are shown in a straight line shows only their conditional location. The distance between the earth and the moon, for example, is approximately 400,000 km. However, it is very common to see representations where the Blue Planet and its natural satellite are so close that we do not understand how far these stars really are from each other.

5 – Asteroid Belt

The same problem with space distances in the solar system occurs to portray the asteroid belt. In fact, if a spaceship ends up falling in the belt, its pilots don’t really have to worry about bumping into giant space rocks. The average distance between asteroids is several million kilometers.

6 – Drop

We are very familiar with the image of what would represent a drop. It turns out that this is just another image that does not reflect reality. A drop of water really has a spherical shape. But it is more like a ball than a tear. Tear is like the heart, which has nothing to do with its actual appearance in the human body.

7 – Sensory zones of the tongue

Studies on taste buds began in the early twentieth century. At that time, it was assumed that there were several taste sensory zones on the tongue. Each of them being responsible for a particular taste. There is even a map of the language where each of these regions is shown. However, science has been able to prove that all kinds of taste receptors are distributed throughout the language.

Although its distribution density is uneven, scientists have not been able to prove whether a particular area is responsible for its flavor alone. There are more taste receptors than just the 4 previously thought. In addition to sour, salty, bitter and sweet, there is umami, a taste sensation caused by monosodium glutamate.
