Still looking for something fun this summer?

One of the most mind-boggeling, thought-provoking, get students to completely change their conception of thinking, math and more, is

Godel, Escher, Bach.

And best of all MIT has created a free class based on this book, complete with lectures, notes and more.

If you undertake this journey, the rewards will be immense, and you'll certainly have your mind blown more than once.

March 1st

The big idea for today that as the radius of a planet increases, its centripetal acceleration decreases. Also, the acceleration of the earth divided by its radius squared is almost the same as the acceleration of the moon. I think.

Friday, February 26

Today in class we had a double period that consisted of meetings with Mr. Burk for about 25 minutes about the projects, and working on them while other groups met. The big idea for projects is looking ahead and finding something new to master.
Hw:6d and webassign, work on project

Scribe is Mary Elizabeth

last wed class

First we took a blast from the past energy re assessment , and then we talked more about the moons lab, and finally we worked with the vandegraf generator.

Important ideas were that objects will repel each other when on the vandegraf and that to linierize the orbital period vs radius, you need to raise the radius to the 1.5 power.
next scribe is Burge.

Today in class we went over 6c and did a problem in class.

The problem was with a square where one side has a length of 0.5 meters and all the charges are equal and are +or- depending on the charge of the point and is equal to 50*10^-6:

1)Find Fe on 1

2)Find E at location of i

3) Find any place(s) where the electrical field vector is 0

4)Find E at A

5)What force would a -20muC charge feel at A?

Class on 2-17

Today we worked on our projects. Homework was 6c. The next scribe is Paxton.

Class 2/16/10

Today in class we talked mostly about Coulombs law. Coulomb's law is basically an equation that states that Fe=(k*q1*q2)/r^2. We also learned that constant K always equals 9*10^9. Using this information, we can find Fe as long as we know the charge of 2 objects and their seperation distance!

1.) If we find out the net charge of an object and divide it by the charge of an electron (always 1.6*10^-19) we can find out how many excess electrons there are.

2.) Also, one atom has an area of 4*10^20 so if we divide the area of the object by that number we get how many atoms there are overall.

If we divide (1) by (2) we can find how many electrons were transferred when the object was charged! yaaay..

(I tried to keep it short and sweet :]) next scribe is Joe!
