Demonstrates Galileo's law of odd numbers

Quiz Scheduled for tomorrow:

  1. How_things_work_college_course/Conceptual_physics_wikiquizzes/Velocity_and_acceleration
  2. How things work college course/Conceptual physics wikiquizzes/Uniform circular motion

Lab: Prove Galileo's odd number law. Let's do this right by including historical significance. We will use the area rule, but also justify it using the concept of a Reimann sum. The class report will go in

brief statement with good photo
Useless, but why need an open source bank (or maybe why we don't?)
This was supposed by by invitation only
Probably the best. Requires knowledge of if x=0 at t=0.

Looked at Physics for Beginners: http://www.thenatureofthings.info/physicsframe.htm

I would like to develop "cluster questions" based on this material. The student would read an edited passage from the text and answer multiple choice questions based on the content of the passage. The motive for taking this approach is that most students who have access to both the text and the questions will just read and learn the questions. They will either not read the text, or they will lightly skim the test.

Unfortunately, I don't think the author's statement releasing the material actually authorizes a quizbank to convert his prose into questions. I contacted the author two days ago by email and am awaiting a response from him.

  • 1:15 Citizen Four

Nasa's CO2 data was shown.[1] There is evidence of change. But is it because of us? Is climate change a cause of the wildfires?[2] Nationalgeographi.com.

Everything happens for a reason. We have no right to say what nature does. We can and should do our part as individuals, e.g., purchasing electric cars.[3]

  • Citizen Sixtyone

Noted that Four said if nature is allowing globalwarming, who are we to change it. Why is nature “allowing it”. Im not a 9 because I don think it is critical yet. Over the past 70-100 years pollution of all varieties has increased. [4]We as a species need take resoonsibielity and do our part to lesson pollution. Nature allows it? Is the Earth a living organism that can adapt?

I can't believe people are still studying this plasma instability![edit | edit source]


09-24T When will fusion happen?[edit | edit source]

61: When will fusion happen? Belief that it is in our future, but don't know when. Problem: How to containt he plasma. Also, it takes much energy in than comes out. All current efforts consume more energy than they produce. Finally, (third) there is cost.

Private sector is taking over. ITER in china: Size of Mall. MIT hoping to be ready by 2025. JET has had some success. 61 thinks 50 years as a generous (optimistic) estimate, but 61 believes it is inevetible.

  1. I trust this data ~~~~~
  2. Not certain, but I think the answer is NO ~~~~~
  3. My understanding is that electric cars can alleviate our CO2 emissions, but only to a limited extent (we need to generate the electricity and solar/wind power will probably always be expensive in both dollars and energy consumption)
  4. I suspect the real pollution started circa 1800~~~~
  5. According to Wikipedia, there is scientific criticism of this movie. For example, I don't think Ice Ages have sudden onsets~~~~
