Five wrong facts we learned in school

Let's start with a little test of our information:

  1.    How many senses?
  2.    Which is magnetic: paper clip, tomato, or you?
  3.    What are the primary colors?
  4.    Which area of the tongue is responsible for the bitter taste?
  5.    What are states of matter?

  • If your answers are: (five, paperclip, red + blue + yellow, back of the tongue, gas + liquid + solid) you will take a full score on a school test, but you will be wrong!
  • The senses are more than six:
  • Taste, touch, vision, hearing, and smell do not represent all of the senses.
  • We feel movement through accelerometers in the vestibular system within the ear.
  • The movement of fluids over small channels deep in the ear allows us to feel movement and steelyard.
  • And it makes us feel dizzy and anxious as well.
When we hold our breath, we feel that our blood becomes acidic as carbon dioxide dissolves in it to form carbonic acid.
And also our sense of temperature, pain, and time in addition to a large number of other sensations that allow us to respond to our needs and what is happening around us in the environment.

Magnetic aversion:

Not only is the paper clip magnetic.
Tomatoes and humans interact with magnetic fields as well.
Paper clips and other materials containing iron, cobalt, and nickel are ferromagnetic, which means that they are materials that can be attracted to magnetic fields.
While the water inside our bodies and tomatoes (or more precisely: the nucleus of the hydrogen atom in the water inside our bodies and tomatoes) are repelled by the magnetic fields.
This reaction is called "diamagnetism".
But the forces here are too weak to pay attention to.
This is only if you were in an MRI scanner there, the nuclei of various atoms would be manipulated by a massive magnet, resulting in a detailed view of your body.
You do not have to go to the hospital to see the reactions of "weak magnetic permeability", but you can do a simple experiment at home using tomatoes Watch the video:

You are painting the wrong colors:

We were taught that the primary colors are the colors that cannot be made by mixing, and all the remaining colors can be made by mixing the primary colors.
But the red and blue colors fail in these specifications.
We can create red by mixing yellow and purple together, while blue can be made by mixing purple with the sky.
At the same time, we cannot reach a wide range of colors if we only use red, blue, and yellow.
Scholars agreed on this by the end of the nineteenth century, but for some reason, the curriculum was not updated.
The proof is that the colors of the printer cartridges come in yellow, cyan, and magenta, and these are the primary colors.

The bitter taste in your mouth:

The picture shows the famous tongue map in the school curriculum, as it shows that the bitter taste is concentrated at the end of the tongue, while the sweet and sour taste has its areas.
This map appeared in 1942 after Edwin Boring of Harford University misunderstood a German study from 1901.
Despite Edon's mistake, this tongue map began to appear in school books.
In 1974, the clarification was presented and addressed. Despite this, the map is still in the school curriculum.

Look at your screen status:

  • We all learned that solids hold steady because the particles in this state are arranged.
  • These solids can turn into a liquid by melting them while keeping the same volume.
  • Liquids can evaporate into a gas, which expands to occupy the available volume.
  • These are the three states of matter and this is what we learned.
  • But of course, there is more. Liquid crystals have particles arranged like the arrangement of solids but are fluid as liquids.
  • These properties are essential, for example, for body cells, shampoos, and of course, for flat screens (LCD).

But why to stop counting at four, there is also the state of plasma, which is the case for most of the things that make up the sun, or “Bose-Einstein condensates”, “superfluids” and many more.

Is it time to renew the textbooks?

There are many other than these five facts that need correction.
This article does not indicate that children should be taught about things that happen in the laboratories of Nobel Prize-winning scientists, but we must stop lying to children.
Perhaps the lesson on biology might start with “We have a lot of senses, but now we will learn only five of them.” As for the tongue map, just tear the page from the book!
