Prove Pythagorean Theorem with Einstein's Theory of Relativity? This actually appeared in the textbook of People's Education Edition!

In the eighth grade mathematics self-study textbook published by People's Education Publishing House, it is written that Einstein proved Pythagorean theorem with the mass-energy equation in the theory of relativity, and the proof was published, which shocked the international mathematics community. Therefore, the famous German mathematical magazine Math Ann hired Einstein as the editor-in-chief for many years.

The absurdity of this error is approximately equivalent to:

Switzerland in the southern hemisphere is written in geography textbooks;

The biology textbook says cactus is a mammal;

The history textbook says that Xiang Yu is Napoleon's second uncle;

This is only in terms of absurdity and harmfulness, which is much bigger than the above three fallacies. Because the above three are simple factual fallacies, it is easier to correct them. The absurdity of this "proof" in the original question is reflected in the method level, which is difficult to correct.

If this fallacy really appears in the publications of People's Education Edition, it is artificially adding an authoritative false "proof" to the inherent difficulties of this original teaching task, which will cause endless harm.

This is why we should resolutely oppose those acts of spreading pseudoscience under the banner of popular science.

Be vigilant and don't shake the textbooks of compulsory education. Do you know how destructive this will be to minors' understanding of science? Exaggerated, this is as irritating as putting pornographic pictures directly in primary and secondary school textbooks.

For teenagers who are in the stage of learning basic knowledge, this is a public opinion war, a struggle between scientific rigorous thinking, scientific exploration spirit and anti-intellectualism. If we fail, fallacy may become authority. At that time, scientists may need to defend their actions, and anti-intellectual remarks are popular in the mainstream media.

This can no longer be described as a low-level mistake, which reflects the lack of scientific spirit of textbook writers. Therefore, it can only be: the editor has no level of making up or translating, and there is no scientific common sense to check.

This serious textbook should have at least a three-level review process, so that things like this joke can escape the net. What about the rest of the textbook? Do we dare to believe it? Do we dare to teach children?

If the responsible editor has not modified it, then the editing team has no ability to distinguish the authenticity of the material; The editor in charge did not modify it, so the editor did not have the ability to distinguish the authenticity of the material. What the former said shows that the ability of the whole editorial board is questionable. The latter shows that the author is incompetent and the editor is irresponsible.

The publishing house should immediately recall all the textbooks that have been sold, revise and issue them again, publish the errata, apologize to the students, and deal with the relevant editors seriously. The joke has already started, and you can't run away if you are ridiculed by the group. In the spirit of being responsible for children, try your best to remedy it.
