UCSD Physics 10Digression: Why are you here?!

3

“Because I was born.”“My parents made me come.”“It’s just what you do after high school…”“My parents hate me…”“I want to get a job, man”“I’m here to learn—to think—to build my brain.”

College is an opportunity: do your best to seize it!

What I wish for each of you to come out with:Ability to think critically (not afraid to think indep.)Skepticism about information given to you (agenda?)Willingness to see complexity/multiple sides of issue

Expectations

Attend lectures and discussion sectionParticipate!

If it doesn’t make sense, ask! Everyone learns that way.

Don’t be bashful about answering questions posed.

In-class voting system should make this funDo the work:

It’s the only way this stuff will really sink inexams become easier

Explore, think, ask, speculate, admire, enjoy!Physics can be fun, enriching, beautiful

UCSD Physics 10Does it Pay to Come to Lecture?

• No one who came more than 80% of time did very poorly• Few who came infrequently got more than a low B

Homework!!

18

You are expected to answer all the problems/questions.

Only one or two questions will be selected.

Questions and Observations -It will be part of HW.

UCSD Physics 10Class Participation and Attendance

19

All students are expected to prepare for and actively participate in class. I do not expect ‘perfect’ questions or answers.

Excellence means being prepared, involved, and taking responsibility for your own learning.

Mondays’ Questions /Observations

UCSD Physics 10What are these questions/observations? (Monday)

20

Science is as much about questions as answers.Every Monday, you’ll submit a question or

observation about the physical world around you .Something you’ve always wondered aboutSomething you recently noticedSomething that class prompted you to think about

I will choose one submission & you will need to research the topic which will be part of the HW and discussed the following Monday.

Goal is to increase your awareness, observational skillsWe’re immersed in physics: easy to ignore, but also easy to

see!You’ll begin to think more deeply before shoving problem

asideAllow your natural curiosity to come alive

UCSD Physics 10Questions/Observations, continued

21

How do you present your question?

In one side of an index card (4 X 6 in) you will write

Date Name Course and session And below you will write your question or

observation

From the questions that have been submitted we will choose one question to be investigated.

UCSD Physics 10Questions/Observations, continued

22

What kind of question/observation? Questions

What makes velcro stick?Why do my cheerios attract each other into little flotillas?Where do trees get their mass? Out of dirt? Why aren’t

there holes in the ground around trees if this is the case?Why is the sky blue? Why not purple?

ObservationsI’ve noticed small rainbow patches in the sky way off to

the sides of the sun on hazy winter days. What are those?

I’ve heard that toilets flush the other way around in the southern hemisphere, but on my trip to New Zealand, they flushed the same way as they do here! What’s up with that?!

UCSD Physics 10

Let’s try it!!

23

In the piece of paper that the teacher gave you, write on the top left write the following information:

Date Name Course and session Question/observation: I have heard that I could open a jar that is

tightly closed by applying hot water. Why is that possible?

UCSD Physics 10

Let’s discuss it!!

24

You will have 3 minutes to discuss this subject with one or two of your classmates near you.

I will place music and when the music stop, you will return to your seats.

Then, you will have two minutes to sit down and write down your ideas

Now, STAND UP and find a partner.

UCSD Physics 10

What can you tell me?

QUESTIONS?

25

UCSD Physics 10

Clickers

26

We will use infrared transmitters in every lectureAs a check on understandingTo give practice on quiz-like questionsInstant feedback (for me and for you)Surveys/opinion gatheringClass Participation!!!

You will need to go to the Physics and Geology Department (PSB 1.118) to pick up your clicker.

You’ll register your clickers through blackboard siteThrough blackboard you will sign in and go to this class. In

the left side there is a tab that reads: clicker registration . There you just need to enter the clicker’s number.

UCSD Physics 10

How Much !?

27

This course will largely focus on qualitative, conceptual content

That does not mean the ideas are trivial!We will be using

Simple graphsOccasional basic algebraAverages

Don’t let it psych you out when you see it…

UCSD Physics 10

Can I text or use my cel. phone during class?

QUIZ # 1 Date: Name: Major: Course and Session:

31

In the paper provided by the instructor you will answer three questions from the following:

1) Where is Instructor Casquete’s office located?2) Where do you need to pick up the clickers? 3) When will be the final?4) What will happen to you if you are found

texting? 5) When do you need to submit the

question/observation?6) What percentage of your grade is the lab?7) What percentage of your grade is

participation?

UCSD Physics 10Mapping the Intellectual Frontier

Spring 200832

One (but by no means the only) way to organize our ignorance is in terms of length scales

Our intuition and everyday experience spans only a very small range of this scale

Really small “ordinary” Really big

UCSD Physics 10

HW You will need to solve for a variable

Let’s see some examples

Spring 200833

UCSD Physics 10

1) Solve r + 16 = -7

To solve, you must get the variable by itself.

What number is on the same side as r?

16To get r by itself, we must undo the “add 16”. What is the opposite of addition?

Subtract 16

UCSD Physics 10

- 16 -16

r = -23

-23 + 16 = -7

1) Solve r + 16 = -71. Draw “the river” to

separate the equation into 2 sides

2. Subtract 16 from both sides

3. Simplify vertically4. Check your answer

by substituting your answer back into the problem

UCSD Physics 10

2) Solve x + 2 = -3Get the variable by itself. What is your first step?

1. Add 2 to both sides2. Subtract 2 from both sides3. Add 3 to both sides4. Subtract 3 from both sides

Answer Now

UCSD Physics 10

2) Solve x + 2 = -3

- 2 - 2

x = -5

-5 + 2 = -3

1. Draw “the river” to separate the equation into 2 sides

2. Subtract 2 from both sides

3. Simplify vertically4. Check your

answer by substituting your answer back into the problemOn homework, be sure to check your work!!

There is no reason why you should miss a problem!

UCSD Physics 10

3) Solve 8 = m - 31. m = 52. m = 113. m = 244. m = 8/3

Answer Now

YOUR TURN

UCSD Physics 10

3) Solve 8 = m - 3 + 3 + 3

11= m

8 = 11 - 3

1. Draw “the river” to separate the equation into 2 sides

2. Add 3 to both sides

3. Simplify vertically

4. Check your answer by substituting your answer back into the problem

UCSD Physics 10

4) Solve. 3x + 2 = 4x - 1

You need to get the variables on one side of the equation. It does not matter which variable you move. Try to move the one that will keep your variable positive.

UCSD Physics 10 4) Solve 3x + 2 = 4x - 1

- 3x - 3x

2 = x - 1

+ 1 + 1

3 = x

3(3) + 2 = 4(3) - 1

9 + 2 = 12 - 1

1. Draw “the river”2. Subtract 3x

from both sides3. Simplify4. Add 1 to both

sides5. Simplify6. Check your

answer
