What is the ideal experiment for twins, and the current educational significance of the same type of

The Twin Ideal Experiment, also known as the Twin Paradox, is a thought experiment on the special theory of relativity. Here's how it goes: There are twin brothers, one of whom takes a long-range space trip near the speed of light on a spaceship, while the other stays on Earth.

As a result, when the traveler returns to Earth, we find that he is younger than his brother who stayed on Earth. This result is inferred by the special theory of relativity (the phenomenon of time dilation of a moving clock) and can be verified experimentally: we can detect mesons produced in the upper layers of the atmosphere.

Without time dilation, those mesons would have decayed before they reach the ground.

In October 1905, the German journal "Annals of Physics" published an article "On the Electrodynamics of Moving Bodies", which announced the advent of the special relativity hypothesis. It is this seemingly ordinary ** that establishes a completely new concept of time and space and challenges the obviously simple concept of simultaneity. We know that Einstein's special theory of relativity can be concluded that there is a time dilation effect on moving objects.

At the Bologne Philosophical Congress in April 1911, the French physicist P. Langevin used the twin experiment to question the time dilation effect of special relativity, envisioning a pair of twins, one staying on Earth and the other traveling to space on a rocket. Flying at nearly the speed of light, one of the twins who traveled in space was only two years old when he returned to Earth, and his brother was long dead because 200 years had passed on Earth.

The Twin Paradox: A Thought Experiment on Special Relativity.

Do you mean an experiment on Einstein's theory of relativity, or do you?

There is an "optimal education period" for any training file search or educational content aimed at a specific trainee. At about 52 weeks, children learn to climb stairs with the best effect, and can achieve the best training effect in the shortest time.

Education should respect the actual level of the child, wait patiently before the child is mature, do not go against the natural laws of the child's development, do not go against the internal "schedule" of the child's development and artificially accelerate the child's development through training.

Gesell, an American psychologist, once did a famous experiment: the subjects were a pair of identical twins A and B who were born 46 weeks ago. Geselle first asked A to climb the ladder every day, and after 6 weeks, that is, in the 52nd week, A climbed 5 ladders in 26 seconds.

In week 53, it took 45 seconds to climb the ladder for B without any training, and Geselle trained B to climb the ladder for two weeks, and by the 55th week, it only took 10 seconds for B to climb the 5 ladders. Although A trained seven weeks earlier than B and trained three times as long as B, at 56 weeks and at 3 years old, Gesell found that A and B had strikingly similar ladder climbing results.
