Even Einstein was human

Even Einstein was human

The problem with Albert Einstein is that he and his ideas are so fantastic and the same time so massive, that we cannot question them. So when we are thinking about Einstein's theories, what was fundamental in his lifetime, or when he introduced them to the world, we must remember two things. 

Einstein didn't have supercomputers, and when he introduced the Theory of Special Relativity in 1905 and Theory of Common Relativity in 1915, those theories became two of the most awesome and well-known formulas. But we don't know why Einstein created those formulas? Who ordered that man make those theories, and what was hypothesis when that job was given to Einstein? 

So there is another thing, what we are many times forget to ask, and that thing is "what were the values, what Einstein used? Did he use the theoretical speed of light, what is 300 000 m/s or did he used the value, what was metered by Michelson, and what is approximately 299 792 458 m/s? The thing is that there are differences with those numbers. And when we are thinking about the time, what Einstein used for creating those formulas, he made excellent work. But he 'forgot that the space is never straight. 

When we are calculating things by using extremely long decimal numbers, we can say that Einstein's formulas are not matching with reality. That means that those famous formulas are working in the common and enough large scale, but when we are going to the very small areas there are mistakes. So Einstein's theories work with entirety, but unique details are problems. This is the problem with physics and every other formula in the world. 

Those formulas are made in the time, there were no supercomputers and float number algorithms, which can handle extremely long decimal numbers, which gives enough accuracy for calculations. Sometimes people have asked, what if the value for the speed of light, what was reported by Michelson was wrong? In that case, every single laser ranger in the world would show the wrong numbers. 

This would open the route for very interesting philosophical discussions about things, what might be wrong, but commonly thought to be right. And if we would someday meter the different value for the speed of light, what would we do? Would we replace the speed of light and other meterings, where were used the laser meter again?

A couple of words about theories.

A couple of words about theories.

If we want to prove theories wrong we can use some scientific facts for that. Or we can say that metering systems have been broken in that time. And one version to say that somebody is wrong is argument things by saying that we have believed that thing over 200 years. Or we can say that we have a room at University, and that's why other people must believe us. Then we can go to make publications, which is full of very complicated formulas, and then nobody else understands those things.

Wikipedia is claiming that the computer cannot have a limitless capacity to calculate data. Then we might ask, whoever said the thing, that the computers might have limitless capacity or speed to handle bits. Every tool in the universe has limits. Even theoretical quantum computers have limits. They are fast but not blinding fast. Human brains have also the capacity to handle information. That is the reason, why many people, who are making difficult things have problems to remember some other things, what might feel normal to us.

Theories are theories until they are proven true. And the process for that is that at the first there is theory, then conjecture, what means theory, what is under observation, and after that, the name of the theory is turned to the law od science. A good example of this is the Riemann's conjecture, what is the formula, where is no zero-point, and what is used to calculate the binary numbers in the field of mathematics.

In the calculations like proving the truth that Riemann's conjecture has no zero-point is needed to use very high-power and fast computers. This is a really interesting paradox because if the Riemann's conjecture continues forever without zero-point we cannot ever calculate all numbers. And there is always the possibility that the formula would reach the zero-point in the next number.

So this is one way to observe the calculations, what is needed extreme powerful computers. Those binary numbers are needed to secure data transmission. The idea of mathematics is that this science is a pure abstraction. But the proofing hose formulas must be done by using mathematical rules. This thing is many times mentioned in many books and texts. The thing is that every theory has weaknesses.

When we are talking about geometry, we must remember that the same computers, what are calculating the Riemann's conjecture in the very long time, would handle things like triangles by very high speed. And there is one biggest mystery in mathematics. Does Pi, the relation between the length of the circle and its radius has something called precise value. The computers have calculated billions of numbers for that thing, and that is 3,14 and many numbers behind the dot.

Of course, measurement tools have little bit advanced than in the time of Euclide or Pythagoras. Sometimes I have thought that those men didn't have the compass, which is equipped with the meter, where is possible to mark the beginning point of the circle, and then when the drawer makes the circle the graduation shows the exact length of the circle.

That thing didn't the value of Pi at all, but anyway those tools are really interesting advance for mankind. That is one of the most boring books in the world. This thing has been given an idea to calculate the triangles by using extremely long decimal numbers, and because the results have become more accurate, there is founded mistakes between calculations and real-world images.

So that thing has been brought the new way to think about things. The new evidence would be brought a new kind of tools. And when we are thinking things like cosmology, what is a little bit like physics, there is one difference between those things. The cosmology has lost the will to prove everything by using calculations.

The thing that the black hole pulls material and photons inside it would mean that in this really specific place in the universe could happen something, what is not possible anywhere else. But actually, we cannot know does the black hole even pull anything inside it.

How would you solve this mathematical problem?


How would you solve this mathematical problem?

Here is one mathematical formula, or the problem what solution is based on the thing, that the maker of this test must find the formula. This problem is taken from the "Newsners" home page, and it is published on Facebook.

As you see there might be two or three solutions, depending on what system the solution maker want to use. The examination is on the page, what is linked below this text, and simplest way is just plus the numbers if the last line, and the answer would be 19, but that would not follow the formula, what is in the problem.

1+4=5
2+5=12
3+6=21
8+11=x

There might be an answer that the last number of the problem would be multiplicate the last number with the line order number, and that thing can demonstrate by using the plus mark. That means that the solution for this mathematical problem would get by using the next formula.

1+4=5
2+5+5=12
3+6+6+6=21
8+11+11+11=41

The source homepage answer you might read from the next link, and that is also the source of this problem. As you might see, there could be many ways to solve mathematical problems. The answer is taken that the last number of each line would plus to the next line. And you might see that would also give the correct answer for that formula.
