Even the most simple creatures study the environment, but only the most advanced – man, it was he who got the farthest point in this direction. But looking for answers to questions is not only associated with successes and “facts”, but also with many errors.
But this is simply part of the scientific work, and sometimes a misunderstanding can allow the right person to be created. Most importantly is imagination, new ideas, opinions, and trends. While most of them may be on the verge of nonsense, one strange, unimaginable idea may be the right one.
The six-thousand-year-old Earth is the center of the universe
Earth is the center of the universe and all surrounding things revolve around it. That was the idea Geocentrism, Which later evolved from it HeliocentrismWhen the center of the universe was to change the sun. But as it turns out, the sun is not only in the middle, but rather a star, of which there are billions of them in the entire universe.
And so our ego was hit hard. The question now remains when will we officially affirm that we are not alone in the universe. Unfortunately, the evidence is the closest to a few light-years away.
As early as the seventeenth century, according to the Bible, the approximate age of the Earth was calculated. It was to be “created” in the year 4004 BC. Scientists’ estimates have ranged over millions of years in the past. According to the latest information from Radioactive Dating he is The age of the earth Almost 4.54 billion years. The results were also confirmed by examining meteorite and moon samples.
An atom is the smallest particle
The atom has always been the cornerstone of all the substances that make up ourselves and the things around us. However, in the end, it is not the only and last block. According to the latest theories, it does not form a significant part of the universe, only 4% of the total mass.
However, the atom is made up of smaller particles, whether they are protons, neutrons, or electronsStandard form It consists of elementary particles in the form of quarks and leptons.
Water, Earth, Air, Fire and Phlogiston
Phlogiston theory It’s named after JJ Becher another ingredient is supposed to be beside him Four classic (Fire, water, earth and air). It was supposed to cause the materials to burn. Refute the theory Antoine Lavoisier, Who laid the foundations of chemistry, the law of conservation of mass and the formulation of the function of oxygen in combustion.
You can recognize a human by his skull
The first appointment Pseudoscience Experienced the so-called Physiognomy, Which described, under the auspices of professional conclusions, the relationship between the shape of the skull and the personality traits of people. According to this theory, the future convicts could only be detected by the shape of their skull. Fortunately, this was disproved, and this pseudo-science was eventually rejected.
Physiognomy is also a great example of how an illogical assumption can be expanded and developed to great proportions. How important is the emergence of a critical and unbiased analysis of other scholars who are not “steeped” in theory.
Heavier objects fall to the ground faster
a favour Galileo Galilei Humanity deserves great and important progress. Many greats, including Newton and Einstein, considered him the first founder of true scientific methods. In his experience, he confirmed this Acceleration of gravity It affects all things equally.
For a long time lonely Leonardo Da Vinci Because he assumed that heavy objects fall to the ground faster than lighter objects. Isaac Newton He later developed Galileo’s theory into general laws of gravity, and then Einstein transformed knowledge into cosmic dimensions.
The soul is in the heart
The heart is the most important part of the circulatory system for transporting nutrients into the blood. He is responsible for this discovery William HarveyWho examined and revealed the functionality of this system. He was mocked for his views, but this is a trap for the pioneers.
One of the experiments in which William Harvey examined the behavior and movement of blood in the body
Until then, it was believed that human spirit and intelligence were hidden in the heart, and the liver instead ensured the circulation of blood. Today, we can replace the heart, this organic pump, if needed.
Humans use only 10% of the brain
An erroneous statement that first appeared in a philosophical material.The energies of men From 1907. The brain is used throughout its structure during the day and at night, when memory is repaired and restructured. Long-term MRI tests also examined this.
Energy consumption of the human brain as measured by a pet
When it comes to energy density comparison, the human brain consumes about 20% of energy, and the remaining 80% is dedicated to other processes and organs in the body. Although the human brain makes up only 2% of the body weight, it requires 25% of the total amount of oxygen or even 25% of the total available glucose.
A phrase that can be described as a very stable hoax. The idea of the five senses goes back to the time of Aristotle, who, however, did not believe it to be a finite number.
The problem lies in the precise definition of the word “meaning,” because, for example, a human being or a human body can perceive dozens of different physical and chemical properties and processes of both external and internal origin.
Aside from the classic concept of light (eye), taste (tongue), sound (ear), touch (skin), and smell (nose), we must not forget things like the ability to perceive heat (skin), acceleration of gravity and field (inner ear), basic perception of time. (Circadian rhythm) as well as perception of hunger (stomach), lack of water, lack of oxygen, pain, need for excretion and many other things, all of which are processed in the brain
In animals and plants, other “senses” can be found that the human body does not possess – for example, the perception of an electric field and light (in plants, the eye is not needed) and the like.
Neutrino is faster than light
Already in 1679 the scientist tested Ully RomerThe speed of light is finite and by gradually improving the measurement we arrive at the current value light’s speed In a vacuum 2,99792458 meters per second. In 2011, a rift occurred due to the discovery of the scientists investigating NeutrinosIt is a little faster than light.
A large scientific community responded to such an unexpected report, and repeated measurements of the neutrino velocity were immediately made. In the end, it was found that the fault was in one of the electrical cable, causing the measurement inaccuracy due to the damage. So the speed of light is still top.
What does a unique neutrino detector look like? An impressive structure built deep in the earth and containing thousands of large, gold-coated sensors, resembles a science fiction movie:
There is no gravity in space
From today’s point of view, when we know the principles of spacetime and its curvature due to any object, this sounds nonsense, but it has long been believed that there is simply no gravity in the universe, or that it is not working.
The truth is that everywhere in the universe there is some action of gravity, even in miniature form, when, for example, there is nothing for thousands of light-years. For example, in our orbit, where the International Space Station and satellites are located, there is roughly the same gravitational pull as there is on Earth. “Hover” occurs due to the free fall effect.
Although NASA, for example, talks about “zero-g” or “microg” and the like, it is a standard term that says nothing about the force of gravity. While on Earth the acceleration of gravity is 9.81 m / s2, in an orbit 9 m / s2. Up to one light-year from Earth, the effect of Earth’s gravity can be measured at 400 am / s2. Added to this, of course, are the effects of gravity of other objects according to their dimension and attractiveness.
Mistakes lead to success
The basis of progress is the lessons learned from one’s mistakes and the mistakes of others, the constant verification of correct information, new opinions and opinions. In the past and present, no scientist has escaped mistakes. Nikola Tesla, for example, was convinced that mankind would never acquire the ability to deal with nuclear energy; Many scholars disagreed with the theory of relativity.
The earth is flat, nothing heavier than air can fly, crossing the ocean is impossible, and so are the high speeds of man. There are many such phrases and their authors are very smart people.
Dissatisfaction with an existing theory or opinion often leads to further development.
