How simple ideas lead to scientific discoveries

Adam Savage tell us how simple ideas could help us to made greats discovers with creativity. He gaves many examples such us Richard Feynman, who won a Nobel Prize in physics for his diagrams of the movemento of subatomic particles and he said that he could do that after a conversation that he had with his dad whenhe was a kid. When he was a kid he noticed that when he pulled his wagon the ball that is over the wagon always went to the back and when he ask to his father why happend that his father said that it was inertia; or Eratosthenes, who made one of his biggest discoveries because of a letter that he recived when he worked on the library of Alejandria, discovered the size of the earth only observing and thinking a little. He understood that if someone could see their reflection was blocking the sun when they look down a deep well it's beacuse the sun is directly above the city of Swenet , also he know that a stick stuck in the ground in Alejandria at the same time gives a shado that has 7.2 degrees off-axis. After that he only needed know the distanbe between Alejandria and Swenet and then multiplied by 50. He got 25000 kilometers but that is only the one percent of the real dimension of the eart, Armand Fizeau was a experimental physics, he was confirming people's discovers also he was familiar with Galileo's experiments who was trying to detemined the light's speed but when Galileo culdn't determine that because the thougt that the light was so fast that it was difficult to determine Fizeau solve it only with a toothed well, a mirror and a  beam. To understood science it could be a good idea if you look at the story and how they came to understand it. 

OPINION

Science is a very interesting field of study but it's nescesary have a lot of  concentration, imagination to understand this field. Studying old discoveries or ideas will help us  make discoveries as important.

                Simon Sinek: How great leaders inspire action

He explain us why sometimes people don't achieve their objective when it seemed that they're going to do it or when people achieve them when it seems impossible. He mention Apple like an example of a good company that has nothing special but their are leaders. Also he mention Martin Luther King and the Wright brothers, they were not the only one that try to do something different but what made them different? why others companies or people who tried or try to have that success does not has the same results?He noted that all the great and inspiring people has the same way of communication that is the opposite to the rest. With his idea the made a pattern that he call "The golden circle".
People usually communicate their ideas saying what they do, how they do and finally why they do. But , for example, Apple say why they do , how they do and finally what they do. The opposite of the rest, and people feel that what Apple is saying is inspiring. People don't buy what you do it, people buy why you do it.
 
OPINION

If we started to communicate first explaining why and in the end the goal we would achieve more people to believe in us, if we want a change we would be more easy in the same way if we want to sell a product. It's all in the way you communicate.
