has just about everything from the CUNY
textbook. A subset was chosen that could reasonably be covered in a semester
and this subset was placed first. It's arranged in linear order so that a
student could teach with it. All one has to do is scroll the browser. It can
be further customized to tune the difficulty level. In the last section there is
material for ambitious students. I took the trouble to track down every useful
figure and animation on Wikimedia commons. The students found resources
such as wikipedia and khanacademy to be either awkward or overburdened with
calculus.

The students were unsatistifed with the
problems in the hardcopy textbook (and from online sources) and so I made a
stockpile of problems, indexed by subject and difficulty. The students liked the
fact that they were on relatable subjects and they did a deluge of problems,
well beyond what was assigned.

Stockpile of gameshowstyle questions, indexed
by subject. This makes it possible to test stuff that wouldn't be suitable for a
conventional exam. Some questions are priceisright style where each student
writes a number on a piece of paper and the point goes to whoever is closest to the
actual number.

Followed the subjects from the hardcopy lab
manual, plus optional background material for each lab. There are more than a
semester's worth of labs here and so students can work at a faster pace if they
wish. The concrete labs covering the mechanics of measurement are first.
Early on there is a discussion of how to measure velocity with a phone video
and this technique is used for many subsequent measurements. Measuring visual
resolution optometriststyle was also a useful starting point for other
measurements.

Astronomy textbook. Same strategy as the physics textbook.

Most of the calculations in the textbook use a "Fermi style" recipe, designed to be simple and univesal enough to apply to a large variety of calculations. The recipe consists of 4 columns shown below with a monospace font to align the columns. The equations are almost always the fundamental units equations. One can deliver a lot of information with a small number of symbols.
Example:
Column 1 Column 2 Column 3 Column 4 Description of Symbols Equations Numerical the variables for the for the example and variables variables units Gravity constant g = 10 meters/second^2 Mass M = 80 kg Height of staircase X = 10 meters Time to climb staircase T = 5 seconds Average speed V = X / T = 2 meters/second Energy gained E = M g X = 8000 Joules Power P = E / T = 1600 Watts
In order to have something for everyone, the physics material is divided into levels. Many students wanted advanced material.
Level 1:
Units
Magnitudes
Measurement
Be able to estimate magnitutes by eyeball without help from a measurement device
Calculate formulae in scientific notation
Units formulae
Fermistyle units calculations
History of science
Quantitative mechanics, minimalist style
Wave equation
Level 2:
Temperature
Pressure
Intermediate mechanics
Qualitative understanding of angular momentum
Quantitative understanding of waves phenomena
Qualitative overtones and resonance
Qualitative electromagnetism and nuclear
Level 3:
Advanced mechanics
Quantitative angular momentum
Applications of mechanics, as voted by the students
Optional material:
Earth science www.jaymaron.com/energy/energy.html This was a popular topic for its connection to current events. Rich source of Fermistyle calculations.
Astrobiology www.jaymaron.com/astrobiology/astrobiology.html
The Bennett textbook is great for just about everything except for astrobiology,
where it is weak. Astrobiology proved to be the most popular astronomy topic.

The Wikipedia physics and astronomy textbooks aren't wellenough developed to be useful but someday they will be. A student could make a tangible contribution to humanity by helping to develop them. I'm going to be moving my material to these textbooks. It will be interesting to see what the Wikipedia textbooks end up looking like after everyone has had a chance to express their input.
A set of readings is assigned prior to each lecture and a game show style contest is held during lecture on the material, with bonus points up for grabs. Students would rather play a game show than take a written quiz.
