In time, many scientific concepts entered our lives, many concepts became facts that even children now know. The emergence of some of these concepts is quite new when you consider it.
The main difference between practicing and doing science is that when you do science, something why is that is trying to find. To give an example, if you are building a ship without knowing the concept of density, you are making use of practice. When you solve the concept of mass, I throw it beyond saying “Maple will be heavy, not ship”, you can build huge machines from metal.
Another important feature is verifiability science does not always give the most correct answers. Sometimes one explanation can be refuted by another experiment. An anti-thesis is developed for each thesis, and new, more accurate information emerges at the end. The Pisa Tower Experiment is one of the examples of this situation.
Galileo, let the raft come daddy
Although it is debated whether Galilei Galileo did or not which made him a great reputation He had an experiment. It was said that in this experiment, which is said to be carried out between 1589 and 1592, the famous scientist threw two cannonballs down the top of the Pisa Tower, known for its curved stance. These cannonballs were a mixture of gold and lead. The rates in the volleys were different.
Galileo usually “The world spinsAlthough he is known for being burned and executed for saying very important was a name. He also found the telescope. In particular, it was tampering with the stereotypes of the past and leading to the refutation of some of them.
One of these theories was the theory of gravity. About 2000 years before him He wanted to test the theory of gravity proposed by Aristotle. At this point, he first developed an intellectual experiment. Accordingly, he had to have two objects with different weights.

It never happened when I collected them all
Aristotle’s theory of gravity It’s pretty simple: Heavier objects fall faster. So if you throw away a gold nugget and a feather, the gold nugget will drop first. Lead and gold mixtures will hit the ground at different times depending on their structure. Galileo’s question, on the other hand, was about getting one step further.
Technically when you combine two balls you get a heavier object. In this case, the compound body has to make the fastest fall, but it does not happen. The fall time is somewhere in between the falling times of individual objects.
The first explanation that comes to mind density though, eigen mass was actually only one of the variables. The main factor was air friction. To prove this with an experiment, after Galileo’s death exactly 329 years would have to wait.

Galileo was right with the experiment on the moon
Calendars 2 August 1971Apollo 15 was on the Moon when he showed. Dave Scott, commander of Apollo 15, repeated Galileo’s experiment with a hammer and a feather in the airless environment of the Moon. The objects that Scott left at the same time, as there is no outdoor resistance simultaneously hit the ground. You can watch the video of the experiment above.
You can actually easily test this phenomenon yourself. All it takes is a umbrella actually. Leave the umbrella from a high place, first closed, then open. Although it is the same umbrella and the same setting, there will be a dramatic difference.
Well if there were no open air friction what would it be We could not do such a scientific study because every time it rainslife forms on the planet would be full of holes. A little bloody ending, but nothing to do. (I don’t know where I got the rain that would rain without atmosphere, though.)
