Electromagnetismo

P.C.C --> La carga eléctrica no se crea ni se destruye, solo se transfiere (redistribución)
Ley de Cargas --> Si las cargas son iguales tienen repulsión. Si las cargas son diferentes tienen atracción.

Ley de Coulomb

Fuerza Gravitacional

Permitividad reletiva o coeficiente dielélectricaà Er=F÷F`

Cuando;

Er= permitividad relative del medio (admisional)

F= valor de fuerza elétrica entre las cargas en el vacío en Newtons (N)

F`= valor de fuerza elétrica entre las misimas cargas colocadas en el medio en Newtons (N)

-->La relación que existe la fuerza elétrica de estas mismas cargas sumergidas en algún medio o sustancia aislante.

PAN - JOSEFINA

Educación- She said she has a commitment to accomplish total coverage in high school by 2018 so that all youth may access that educational level. In the case of university, to accomplish coverage of 50 percent. She has already improved the system of hiring professional by being able to reach an agreement with the teachers’ union so that that the positions for new teachers would go through a contest of merit. Before that, some teachers, when they were retiring, used to sell their posts, and not necessarily to other teachers.
Energía- One of Josefina's huge proposals is to improve the environment of Mexico. Within this proposal she intends to promote renewable energy sources at the right costs for the Mexican economy.
Ciencia y tecnología- Josefina believes that the productivity is essential for the correct growth of the Mexican culture and economy. Therefore she has proposed to support new productive sciences and technologies.

Ted Talk Derek Sivers --> How to start a Movement

http://www.ted.com/talks/derek_sivers_how_to_start_a_movement.html
Derek Sivers uses interesting footage to help explain his goal of "trying to start a movement. In 2008, Sivers sold CD Baby to focus on his new ventures to benefit musicians, including his new company, MuckWork, where teams of efficient assistants help musicians do their "uncreative dirty work." With this back round he has been able to create a formula (in other words) to form a movement. It starts with the laeder and then take the support of a couple followers then you are one your way. I enjoyed this video becuase our current society needs more of these movements and more people to make it happen by making a change in their lives.

Ted Talk - How to use a paper towel by Joe Smith

http://www.ted.com/talks/joe_smith_how_to_use_a_paper_towel.html
For me it's astonishing to think of how wasteful people can be without even really realizing it. For example Joe Smith exemplifies how 13 billion pounds of just paper towels are used yearly by Americans! If you observe people usually take 3-5 pieces of paper just to dry their hands. At the moment it doesn't seem that significant although if everyone did that every time they washed their hands the number of 13 billion pounds of paper would increase dramatically. In this case we have Joe Smith to show us how to ecologically dry our hands by the "shake and fold" method. This way we get some of the water off by shaking and utilize the most of a single piece of paper towel by folding. The whole concept of this idea seems silly at first but helping reduce things like the waste of paper will help conserve earths resources and true beauty.

Experimento de Ondas (con el pendulo)
--> Today in physics we experimented and observed the waves formed by a pendulum.

Line of equilibrium

Our pendulum consisted of a container with a hole at the mouth and a string attached to the base to form a swinging motion when moved.
With sand placed in the pendulum and paper underneath the pendulum, we first let it swing to see the line if equilibrium that the sand made on the paper.
Second, we tested to see the waves of the pendulum by steadily moving the paper underneath the swinging pendulum.

Waves of pendulum

From this we can approximately see that how the pendulum moves in a wave like motion.

Ted Talk - How to buy happiness.

http://www.ted.com/talks/michael_norton_how_to_buy_happiness.html
Micheal Norton talks all about how people can in fact buy happiness. Although, man people think of this as buying items and different things for themselves to improve their lives, but this is not the case. The phrase of money CAN buy happiness is true if put in the contents of --> if spent properly. Ultimately, money (a majority of the time) makes people selfish there for making them socially incompetent and unpleasant to be with. If money was spent of different things, or in other words, different people, it is proven to make one happier no matter how much you spend. This theory has been tested world wide and has proven itself very true. From the words of Mr. norton, "The specific way that you spend on other people isn't nearly as important as the fact that you spend on other people.” Meaning no matter what you give someone else, it will make you happier than anything you buy for yourself. So the question is, what can you do to benefit others with your money before acting for yourself?
