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

editLooked 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.

edit- 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?

Nuclear Energy
edit09-17T (week4)
edit- The Wikipedia article w:Fusion_power#History_of_research bothers me. How can a technology that is estimated to be ready in 50 years (if we spend enough money) be called in its "early stages of development"? At good starting point for the fusion energy program is 1963, which makes the current effort 56 years old. That suggests we are either halfway to success or halfway to going nowhere. Personally, I believe we should always making some effort to develop fusion energy, but am not optimistic about its prospects. Are we currently spending too much or too little? I am not qualified to have an opinion.-Guy vandegrift (discuss • contribs) 16:06, 18 September 2019 (UTC)

edit61: 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.

- ↑ Not certain, but I think the answer is NO ~~~~~
- ↑ 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)
- ↑ I suspect the real pollution started circa 1800~~~~
- ↑ According to Wikipedia, there is scientific criticism of this movie. For example, I don't think Ice Ages have sudden onsets~~~~
