Many times it is told to the students that Einstein was fail in Maths exam. But being true this is not the reality. If you read his biography then you would come to know that he was a topper in Maths. But I should say that he was better than anyone in the school, and directly entered college without completing his diploma because of his excellence in Maths. But actually, he was failed in Geography. I can't imagine Einstein fail in Maths.
It is said that Great Wall of China can be seen from Moon. But the reality is that it can't be seen from Moon. This has been clarified by NASA, so I think that it is reliable. If you have seen any photograph of it then it's edited. Belive that it is impossible to see anything from there on Earth.
It is said that in space there is zero gravity but if you have studied Physics at higher level then you would be knowing that gravity is not zero in space. Even if we are nearly 36,000 km away from Earth then gravitational force from would be there, but negligible. But at that point, other planet or other heavenly body would be applying gravitational force.
This is one of the most stupid thing taught in lower classes. It is said that monkeys were our ancestors. Being true, and according to Science, monkeys are not our ancestors but the ancestor of monkeys and humans is the same. We, humans and monkeys have the same father, but monkey is not our father.
