How much is one plus one? Imagination lets us know that it can be equated with happiness, because a kind heart and hard-working hands will create happiness on earth; It can be equal to a nightmare, because all happiness will become a nightmare because of the difference of thoughts; It can also be equal to the future, because remembering the past and cherishing the present can grasp the future.

However, one plus one always equals two.

If a math problem is "1+ 1=", how would you answer it? I think most people will write "2" without hesitation. Of course, the teacher will not hesitate to tick. Why? This is the power of truth.

In math books, we can see the existence of truth everywhere; We also need truth when doing problems. It can be said that truth is everywhere in our life.

The reason is simple, like "1+ 1". However, it is very difficult to prove and popularize the truth, just like a person without armor has to go through dense thorns. Such as the establishment of Heliocentrism.

Heliocentrism was put forward in ancient Greece, but due to the backwardness of astronomy at that time, people's trust in geocentric theory continued unabated. But it was not until16th century that Copernicus, a Polish astronomer, put forward this truth again. But at that time, the opposition of religious forces forced Copernicus to die in the sea of fire.

But there is always a rainbow after the storm. One scientist fell, but thousands of scientists in Qian Qian stood up again. Later, through the efforts of these scientists, Heliocentrism overthrew the geocentric theory. So the facts can be proved.

And, of course, the Curie couple we know well. After unremitting efforts, they faced a black cauldron in a shabby shed, which proved the existence of radioactive elements radium and polonium.

We can't forget Franklin, the scientist who flew a kite with a kite string tied with a copper key in Philadelphia, where it was thunderous. It was his dangerous "Philadelphia Experiment" that proved the essence of current flow.

There are many such examples, so I won't say more.

Now let's see how much one plus one equals, and you may not say some answers except mathematical logic. Of course, I'm not teaching you to write an eight-part essay. I just want you to know that truth is great.
