How many feelings does a person have?

At least nine.

Five - those that we all know, that is, sight, hearing, taste, smell and touch - were first listed by Aristotle, who, being an outstanding scientist, nevertheless often got into a mess. (For example, according to Aristotle, we think with the help of the heart, bees come from decaying bull carcasses, and flies have only four legs.)

The conventional wisdom is that humans have four other senses.

1. Thermoception - the feeling of warmth (or lack thereof) on our skin.

2. Equibrioception - a sense of balance, which is determined by the fluid-containing cavities in our inner ear.

3. Nociception - the perception of pain by the skin, joints and organs of the body. Strangely, this does not include the brain, which has no pain-sensing receptors at all. Headaches - no matter what we think - do not come from within the brain.

4. Proprioception - or "body awareness". It is an understanding of where the parts of our body are, even we do not feel or see them. Try closing your eyes and swinging your leg in the air. You will still know where your foot is in relation to the rest of your body.

Every self-respecting neurologist has his own opinion about whether there are any other feelings besides these nine. And some are even convinced that there are at least twenty-one of them. Say, what about feeling hungry? Or thirst? Feelings of depth? Feelings of meaning? language? Or an endlessly intriguing synesthesia, where feelings collide and intertwine so that the music begins to be perceived in color?

What about the feeling of electricity? Or feelings of danger - when the hair stands on end?

In addition, there are senses that some animals have but humans do not. Sharks, for example, have strong electroception that allows them to sense electric fields; magnetoception determines magnetic fields and is used in bird and insect navigation systems; echolocation and "lateral line" are practiced by fish for orientation, and infrared vision is necessary for deer and owls for night hunting or foraging.

Random interesting fact from the Great Encyclopedia:

Who discovered the atom?

The ancient Greeks believed that everything in existence is made up of atoms. In fact, the word "atom" comes from the Greek word meaning "indivisible", because the Greeks thought that if you divide something until it becomes impossible to do so, the result will be the last atom. Now, even though the Greeks knew about it, we cannot say for sure that it was they who discovered the atom. First of all, their belief in the atom was unscientific: it did not come from any scientific information and was not supported by it. It was just a "philosophical" idea about being and the world.

The atom, as we know, was discovered on the basis of scientific research and theories. Until about the beginning of the 1803th century, the idea of what matter or substance consists of was considered only by philosophers! Then came the English chemist and mathematician John Dalton, and in XNUMX he was the first to develop a scientific theory of the atom.

Dalton was a diligent experimenter. He weighed samples of many gases and found differences in their masses. He discovered that gases, as well as solid and liquid substances, are composed of incredibly small particles, which he also called atoms. He calculated the relative masses for the atoms of the elements known to him. When Dalton established that atoms of different elements have different properties and different masses, he really laid the foundation for the scientific knowledge of the atom.

Of course, there has not yet been a precise explanation of what an atom is and what role it plays. Another Englishman, Ernest Rutherford, almost 100 years later, substantiated a theory of the atom, reminiscent of the description of the solar system: a heavy positively charged nucleus in the center, surrounded by negatively charged electrons.

Today, scientists think that an atom is made up of electrons, protons, neutrons, positrons, neutrinos, mesons, and hyperons. In general, they discovered more than 20 different particles in the composition of the atom. But, what is most strange, there is still no complete description of the atom that can explain everything about it.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

What does a crack in plastic smell like? 12.12.2010

Engineer Christoph Koplin from the Institute of Mechanics of Materials (Freiburg, Germany), having introduced microcapsules with aromatic oil into polypropylene, obtained a plastic that warns by smell about the beginning of its destruction.

When microcracks appear in a plastic product, capsules with a diameter of 1-50 micrometers burst, releasing a characteristic odor into the air. Such plastic can be used, for example, to make a helmet for a cyclist, warning about the loss of strength after a fall or impact.
