## HTW-1 Mechanics

### 08-26M (week1)

Physics Classroom 1-D-Kinematics. HTW-1-Mechanics 1-8

### 08-27T (week1)

Review intro to calculus at PP08

### 09-03T (week2)

Demonstrates Galileo's law of odd numbers

Quiz Scheduled for tomorrow:

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

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 ${\displaystyle x={\tfrac {1}{2}}t^{2}}$ if x=0 at t=0.

### 09-05R (week2)

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.

## Global warming

### 09-10T (week3)

1. 2008 article is largely consistent with current opinions. See pages 3?, 7, 10??, 12? of http://www.wright.edu/~guy.vandegrift/climateblog/smallfiles01/Rahmstorf_Zedillo_2008.pdf
2. I examined Akasofu, Paltridge? and Lindzen on http://www.wright.edu/~guy.vandegrift/climateblog/smallfiles01/100216wikiskeptics.pdf
3. Don't trust the internet: http://www.wright.edu/~guy.vandegrift/climateblog/#donttrusttheinternet
4. The tree-ring problem was hidden in plain sight:

### 09-12R (week3)

I will be here friday for consulation. If you show up, the attendance oucnts. If you don't, a progress report emailed to guy.vandegrift@wright.edu before midnight Friday will suffice for the credit. Tell me if you are ready to talk on Monday.

• 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?

The movie Day after tomorrow. Will Earth do that? [5]

• Citizen Sixtytwo o

Ojects to Patrik j M comment about lies and propaganda. Is Cheny bought by the oil industry? Motion to give sixtyone exactly five minutes (he talked a bit before, ut most went over a couple of

howstuffworks.com: Fusion reactors. We are close to perfection fusion reactors. Best shot is DT. Fifty: Global warming nuanced by politics. Not sure global warming exists. Sees hope in China’s effort as suggestin that a solution exits.

## Nuclear Energy

### 09-17T (week4)

#### Student projects on nuclear vission

All present. Student projects on Nuclear Fission (with one doing a fact-check on nuclear fusion).

#### 09-24T When will fusion happen?

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.

40: Nuclear consequences. Defined. Clean and efficient. Consequences? Cehernobyl. Reactor used graph

## Bell's theorem

### 10-07M (week7)

Dice, Python, WikiJournal of Science/Radiocarbon dating

Homework!

### 10-15T (week8)

Class worked on WJS radioactive dating rewrite at Draft:Radiocarbon dating/Introduction. Unanimous consent to hand this over to other students.

## Conceptual modern physics (second try)

The class elected not to purseu Physics for beginners. We we will try to get modern physics through the internet:

### 10-16W (week8)

Before we do Bell's theorem we need to understand:

Classical theory of light and polarization polarization: Kahn:introduction-to-light-waves/a/light-and-the-electromagnetic-spectrum

### 10-17R (week8)

Lets finish the Khan academy course of the previous day. Some interesting images:

picket fence
File:Quizbankqb d Bell.polarization.pdf

#### 12-part Khan lecture series

1. Uncertainty and the copenhagen interpretation Google search

### 10-29T (week10)

#### Copenhagen convention and uncertainty principle

confined waves do not have a unique wavelength because they are a mixture of waves
1. Easier to follow from hyperphysics
2. b:Waves/Superposition is perhaps the best

Making waves online software boulder colorado

Beethoven's fifth: Hearing the uncertainty

Bell's card game (one day and go on)

### 11-06W (week11) Bell's theorem and binomial statistics

This is the last thing we can do: The question is how long does the game need to be played to establish that Bob and Alice are acheiving the impossible?

### 11-12T (week12) Optics labs

• 1/p+1/q=1/f
• Ray optics in 2 D
• Human eye lab

#### Fermi calculations

• The FCP>I rule (fraction of cost time probability of success must exceed investment in research)
• Do we want to do T-Rex pissing?

#### Great Gate of Kyiv

##### First two chords
1. G2 B2- E3- G3 | E4- G4 B4- E5-
2. F2 B2- D3 F3 | F4 B4- D5 F5
##### Beats of an actual bell sound
1. http://www.hibberts.co.uk/strike.htm
2. w:Strike tone
3. From w:Strike_tone: In chimes, modes 4, 5, and 6 have frequencies in the ratios 92:112:132, or 81:121:169, "which are close enough to the ratios 2:3:4 for the ear to consider them nearly harmonic and to use them as a basis for establishing a virtual pitch."
4. Discussion of piano imitating bells with pedal overtones: https://notesfromapianist.wordpress.com/2016/12/10/exit-via-the-great-gate-of-kiev/

### 12-06F (week15)

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~~~~
