= LEARNER PROFILE AND PHYSICS =

In physics I improve all features of IB learner, as the classes are conducted in accordance with the IB mission. First of all, I get to know a lot not only about Physics, since the classes connect topics from different areas. I particularly high appreciate the use of technology and reflections on nature of science. In my personal opinion, the greatest focus lies on having an open mind and I find it great, that I am not limited to science facts only. From that follow further skills and abilities, such as critical thinking and communication. toc

__ Newton's laws, __ 20th November 2012
What do you think? Have a look....

"Scholars still //barely // understand what Newton’s method was. Did Newton really think his scientific theories were as certain as mathematical proofs? Why did he think his theory of gravity was true, when he couldn’t even say for certain what gravity is?
 * Article 1 ** from Newton's method in three minutes

Newton was able to invent, discover and conceive things no one else could, because seemingly he had invented an entirely new scientific method. He had come up with a whole new way of mathematising physics, and claimed to have achieved mathematical certainty! Philosophers and scientists tried to emulate his method. But no one was as successful as Newton. Whatever Newton was doing, he was doing it right. But what was he doing?

**Article 2 from @http://scienceworld.wolfram.com/biography/Newton.html**

To test his hypothesis of universal gravitation, Newton wrote [|Flamsteed] to ask if Saturn had been observed to slow down upon passing Jupiter . The surprised Flamsteed replied that an effect had indeed been observed, and it was closely predicted by the calculations Newton had provided. Newton's equations were further confirmed by observing the shape of the Earth to be oblate spheroidal , as Newton claimed it should be, rather than <span style="background-color: #ffffff; color: #006699; font-family: Arial,Verdana,Helvetica,sans-serif; font-size: 12px;">prolate spheroidal <span style="background-color: #ffffff; font-family: Arial,Verdana,Helvetica,sans-serif; font-size: 12px;">, as claimed by the Cartesians.

<span style="font-family: Arial,Verdana,Helvetica,sans-serif; font-size: 12px;">Although theories are established by individuals, they must base on the discoveries of others and the common knowledge that is already proved to be truth. Thus the individual has a starting point of their theory, what may be considered as type of collaboration, as there were other's theories, which have led to stating a new one that may be either evaluation or negation of the theories that it follows.
 * <span style="background-color: #ffffff; font-family: Arial,Verdana,Helvetica,sans-serif; font-size: 12px;">How far is collaboration necessary for developing theories? **

Observations of others are helpful and in my opinion it is worth to take advantage of them as they may give new ideas, help to verify whether the new theory is truth or not or lead to crucial conclusions in research made. They cannot, however, be fully trusted and it is good to verify them first by critical analysis, so that they are understood and accepted before being used.
 * <span style="background-color: #ffffff; font-family: Arial,Verdana,Helvetica,sans-serif; font-size: 12px;">To what extent are observations made by other people trusted by scientists for developing their own theories..? **
