Title: Welcome to Physics 4A!


1
Welcome to Physics 4A!
  • Introductions
  • Fill out the survey
  • Meet neighbors
  • Meet me
  • About this subject, and about science
  • About this class (syllabus, policies, etc.)
  • Pre-class Assessment Group Activities

2
Who Studies Physics? Why?
  • Obvious Examples
  • Engineers, Chemists, Geologists, etc
  • Not-so-obvious examples
  • Even less obvious examples!
  • And even LESS obvious?
  • Why study physics?

3
Examples of Physics in our World
  • Scotland Falkirk Wheel
  • France Millau Viaduct
  • China Three Gorges Dam
  • Germany Prosthetics
  • Britain Water-lens Glasses
  • South Africa SALT
  • Geneva Large Hadron Collider

What do these have in common?? What does that
mean for you?
5
My goals for you
  • Help you be competitive when you transfer to a
    4-year university in your discipline
  • which means.
  • Equivalent Rigor
  • Equivalent Expectations for Hours of Study
  • State of the Art teaching with online tools

6
Challenges you face
  • Less time available to study
  • Outside work, family, commuting
  • Lack of support network
  • No Fraternities, TAs, Dorms, Open Labs
  • Library closed early Fridays/weekends
  • Less Advanced Lab facilities

7
but what you DO have!
  • One professor for Lecture/Lab/Discussion
  • Small classes
  • No grade curves you control how well you want
    to do
  • My promise - Ill work as hard as you do
  • I love this subject!

8
Welcome to Physics 4A!
  • About this class Syllabus Calendar
  • Key Policies Attendance Exams
  • Our Textbook
  • Great graphics
  • Wide variety of problems
  • Strong problem solving strategies

9
Mastering Physics!
  • Online Learning Mastering Physics
  • Immediate check you are right/wrong
  • Answer feedback to help you
  • 24x7 availability anywhere
  • Tutorials have multiple levels of hints
  • I can see what you got wrong why
  • Great visual narrated tutorials and resources

10
Additional resources!
  • Blackboard
  • Homework Discussion Help
  • Group Lab report storage/work areas
  • Additional web resources for you
  • TIPERS for discussions
  • PhET and ActivePhysics tutorials

11
Welcome to Physics 4A!
  • Group Work!
  • Introduce yourself again names, majors,
    transfer intentions
  • Set up Mastering Physics access Course ID
    PHYSICS4AFALL2011HILDRETH
  • Try Introductory Assignment
  • Sig Figs exercise and challenge

12
The Scientific Method
  • Richard Feynman How not to be fooled.
  • Observing
  • Trends, Patterns, Singular Events
  • Asking Questions
  • What? When? Where? How? and WHY?
  • Researching prior explanations models

13
The Scientific Method
  • Observing
  • Asking Questions
  • Developing Testable Hypothesis
  • Karl Popper falsifiable!
  • Creating Experiments to TEST Hypothesis
  • Always uncertainty in every measurement result
  • Building a model can be an experiment.

14
The Scientific Method
  • Observing
  • Asking Questions
  • Developing Testable Hypothesis
  • Creating Experiments
  • Analyzing results
  • Anticipate sources of error
  • Refine or Discard Hypothesis
  • Develop further tests Repeat!
  • Compare results w/ existing theories

15
The Scientific Method
  • Observing
  • Asking Questions
  • Developing Testable Hypothesis
  • Creating Experiments
  • Analyzing results
  • Sharing Publishing results
  • Submit a paper to peer-reviewed journal
  • Ask colleagues for input
  • Present at conferences
  • Discuss, Debate, Defend results

16
The Scientific Method
  • Independent confirmation of results
  • Other scientists, other experiments
  • Revising Theories based on results
  • Designing new equipment to test further
  • An example of the process of science?

17
The Scientific Method
  • Observing
  • Asking Questions
  • Developing Testable Hypothesis
