The story of a Superman!

In physic class we have a project called superheros. In there we have to write a story and also create a poster of any superheros about the superheros, powers and compare it to real physics life. On Monday in class we will do a gallery walk of all of the superheros we been researching on.

          Let’s take a look at the sky! It’s a bird, it’s a helicopter, it’s a plane, it’s a SUPERMAN! He can fly, he’s indestructible, he’s is strong and he saves our life! Moreover Superman is a superhero and his superpowers are Invulnerability, Vision, Hearing, strengths, leaping or flying and super Breath. But, how is Clark Kent able to accomplish all of these amazing things that required superpower skills? On the other hand, human can’t have these special abilities like superman so what is the science behind his special abilities and him?

The story started, He was born in this planet called Krypton that orbits around a red star. Krypton was much heavier than the earth which make it clear that the bigger the mass is the higher its gravitational force is. If we look closely, this means that superman on earth is able to fly or jump high because of the small gravitational pull from the earth to him. Krypton planet was destroyed result due to the internal pressures that Krypton’s get. Kal EI (birth name) was send by his father called Jor-El in a small rockets to the earth.

As Kal El grow older, He was raised by his adoptive parents in earth. He was known for Clark Kent who has been shown as superman second personality. Superman was strong and could jump from a building to another and doesn’t required pushing from the ground. He use this power called telekinetic power the ability to move a objects at a distance by mental power. Newton’s Second Law stated “there must be some upward force to balance the downward force of the weight.” So this means that he must use some type of upward force that is higher than his weight in order for him to fly. The yellow sun (our sun) that allow him to fly. He gets energy from electromagnetic radiation which contain in the light of our sun. He also could survive in space, due to his lungs clearly aren’t needed for respiration. Superman metabolize energy from the earth sun light (like human metabolize energy from food) that will allow him to use when he need to fly or jump off from one building to another. Moreover he can stored more than the amount that needed to use for his ability can and also convert this energy into very high kinetic energy. Which in the future will allow him to defeat the gravitational force of our of the earth.

Hedy Lamarr – Women in STEM

On the 18th of January, we had a project to write an article about any Women in the STEM field. My article includes information about Hedy Lamarr and also her inventions that she had created.

 

Hedy Lamarr was born on the 9th november 1913 in Vienna, Austria, the daughter of a wealthy jewish banker. She drop out of school just because she want to pursue her dream, which is to become an actress. In her film career, she had become a Hollywood star in 1940s and she was essentially the equivalent of Angelina Jolie. Hedy Lamarr was once known as the most beautiful woman in the world.

There is no record of Hedy Lamarr talking about her invention to the reporters. Her invention is call “Frequency hopping” and she work on this inventintion with George Antheil. In her off hours, from work she work on this creation.There’s a lot of rumors about her invention. Some says “She is too beautiful, to come up with this brilliant idea.” What I learn from her is that you don’t have to have a high school degree to invent something. What you need is your brain and dot connection. The more you connect ideas from various people the more you can improve your invention. Hedy Lamarr created her device in world war II to assist secret communication, and it also served as an essential building block for wifi, bluetooth and GPS. That we now use these type of thing everyday and we don’t even realize who was the inspiration for these people to create Wifi, bluetooth and GPS. Hedy Lamarr has no science training but have a exceptional scientific mind. She always took things into her own hands and never let anyone control her. She talked to the navy about her invention with George Antheil and provided 7 millions dollars to the USA for the selling war bond. The Navy didn’t us her invention at that time but they it after world war II.

When she grew old, she finally received recognition but she can’t get out of her house. However, she was still able to send voice message to everyone by the news saying thanks you. Hedy Lamarr and George Antheil applied for the patent for her invention on 11th August 1941 under her marriage name “Hedy Kiesler Markey” with a co-founder George Antheil. Then she was honored by Electronic Frontier Foundation in 1997 for her invention. During her life she was quoted as saying “Any girl can be glamorous. All you have to do is stand still and look stupid.” While she was certainly glamorous, as proven by her invention, she was most certainly not stupid.

Math (Probability)

1/15/2018

In the past few week, we were working on probability of simple events and this week we are working on probability of combined events. We have been focusing probability for a while now. Probability is a chance that something going to happens. It seems complicated for the probability of simple events because their lots of symbols that we have to learn and concepts. But for the probability of combined events, we are doing the math to figure out the probability that it will land on something for two or more events.

These are the set notation!

For the probability of combined events, we learn this two concept: Possibility Diagram and Tree Diagram. Which will show all possible events. Possibility Diagram is like a table but we can only use it for two combined events. Tree Diagram is like a branch that would connect from branches to branches and can use for more events than possibility diagram.

This is an example of possibility diagram!

 

This is an example of Tree Diagram!

Physics (Circular motion)

In Physic class now we are working on “Circular motion.” There is three concepts in circular motion: Angular displacement, Angular velocity and Angular acceleration.

Angular displacement – Is the angle of the object that move in a circle

= angular position

 

Angular velocity – the measure of change of angular position

Angular acceleration – is the change of the angular velocity


This is one of homework for practicing Circular motion.
