Conclusion 1:Henri Poincaré

“We must, for example, use language, and our language is necessarily steeped in preconceived ideas. Only they are unconscious preconceived ideas, which are a thousand times the most dangerous of all.”

“Birds,” said the frog mysteriously. “Birds!” And he told the fish about the birds, who had wings, and two legs, and many many colors.

“Cows,” said the frog. “Cows! They have four legs, horns, eat grass and carry pink bags of milk.”

“And people,” said the frog. “Men, women, children!” And he talked and talked until it was dark in the pond.

Ch1-2 Standards of Length Mass and Time Dimensions of Some Common Physical Quantities

Ch1-3 Dimensional Analysis Common Physical Quantities

Concept Question 1.2

Given the following definitions with their dimensions:

v = velocity (L/T)

a = acceleration (L/T2)

t = time (T)

Which of the following equations could be correct as far as dimensions are concerned?

- v = at2/2
- v = a/2t
- v = at
- v = a2t/2
- v = a/t2

Ch1-3 Dimensional Analysis Common Physical Quantities

How does v depend on a and x?

P1.5 (p. 14) Suppose v2 = 2axp

What is p?

Ch1-4 Significant Figures Common Physical Quantities

Concept Question 1.3

- Which statement is correct regarding significant figures?
- 1.355 + 1.2 = 2.555
- 1.478 – 1.3 = 0.18
- 1.513 / 1.5 = 1.009
- 1.5 x 10-3 + 0.1 = 0.1015
- 0.1513 x 1.5 = 0.23

CT1.6 Donovan Bailey – Canada – 1996 Olympics

Donavan is roughly 2 meters tall and that gives the scale. Since they covered 100 m in 10 seconds, each meter takes about 0.1 seconds. The answer is c because they are within roughly 1 meter (half Donovan’s height).

Estimate how many barbers in Chicago? Since they covered 100 m in 10 seconds, each meter takes about 0.1 seconds. The answer is c because they are within roughly 1 meter (half Donovan’s height).

I started by assuming a typical person gets a haircut every two months. Next I assumed that a barber could give about 4 haircuts/hr or 20/day or 100/week or 400/month or 800/every two months. I rounded this off to about 500/every two months since there may be times when the barber doesn't have customers. So a barber could take care of about 500 customers and then they would all come back again. There are about 3 million people in Chicago proper and 8 million in the metropolitan area so I picked an average of 5 million to represent Chicago. That means about 5x106 / 500 or 104 or 10,000 barbers. This is just an estimate and may be off by a factor of 10 either way given all the questionable assumptions!

A Google search listed 1711 barbers around Chicago. two months. Next I assumed that a barber could give about 4 haircuts/hr or 20/day or 100/week or 400/month or 800/every two months. I rounded this off to about 500/every two months since there may be times when the barber doesn't have customers. So a barber could take care of about 500 customers and then they would all come back again. There are about 3 million people in Chicago proper and 8 million in the metropolitan area so I picked an average of 5 million to represent Chicago. That means about 5x10

Ch1-7 Scalars and Vectors two months. Next I assumed that a barber could give about 4 haircuts/hr or 20/day or 100/week or 400/month or 800/every two months. I rounded this off to about 500/every two months since there may be times when the barber doesn't have customers. So a barber could take care of about 500 customers and then they would all come back again. There are about 3 million people in Chicago proper and 8 million in the metropolitan area so I picked an average of 5 million to represent Chicago. That means about 5x10

- A scalar is a pure number. What are some examples?
- A vector has magnitude (value) and direction. What are some examples?
- The magnitude of a vector could be considered a scalar.

Ch1-8 Problem Solving two months. Next I assumed that a barber could give about 4 haircuts/hr or 20/day or 100/week or 400/month or 800/every two months. I rounded this off to about 500/every two months since there may be times when the barber doesn't have customers. So a barber could take care of about 500 customers and then they would all come back again. There are about 3 million people in Chicago proper and 8 million in the metropolitan area so I picked an average of 5 million to represent Chicago. That means about 5x10

- Read the problem carefully.
- Sketch the system.
- Visualize the physical process.
- Strategize.
- Identify appropriate equations.
- Solve the equations.
- Check your answer.
- Explore limits and special cases.

B = beats/second T = time

Mechanics two months. Next I assumed that a barber could give about 4 haircuts/hr or 20/day or 100/week or 400/month or 800/every two months. I rounded this off to about 500/every two months since there may be times when the barber doesn't have customers.
