Chapter 1 About Science<br>
02
Aristotle-3rd Century BC Philosopher (scientist); believed the Earth was the center of the universe
Aristotelian-a believer in Aristotle’s theory of the universe
Copernicus-16th Century Astronomer; believed the Sun was the center of the universe
Copernican-A believer in Copernicus’ theory of the Universe
Heretic-A person who does not believe in the “established theory”
Inquisition-Trial of a person or group because of their beliefs or lack of Galileo Movie Definitions<br>
03
The Most Basic Science
About the nature of basic things
Motion, forces, energy, matter, heat, sound, light
Ideas reach up to more complicated sciences
Uses Mathematics to describe and analyze The Basic Science-Physics<br>
04
The Scientific Method Galileo Galilei (1564-1642) and Francis Bacon (1561-1626) usually credited as creating the scientific method
a method that is effective in gaining, organizing, and applying new knowledge<br>
05
I only wish his name were Pork Roll<br>
06
Recognize a problem
Make an educated guess (hypothesis) about the answer.
Predict the consequences of the hypothesis.
Perform Experiments to test prediction.
Formulate the simplest general rule that organizes the 3 main ingredients: hypothesis, prediction, experimental outcome. Scientific Method<br>
07
Fact-a close agreement by competent observers of a series of observations of the same phenomena
Law-the result of testing a hypothesis over and over and finding no contradictions
Theory-a synthesis of a large body of information that attempts to explain a scientific idea. The Scientific Attitude<br>
08
In order to be classified as scientific, a hypothesis must be testable.
Must be a test for proving it wrong
Example-Which is a scientific hypothesis?
Atoms are the smallest particles of matter that exist.
The universe is surrounded by a second universe, the existence of which cannot be detected by scientists.
Albert Einstein is the greatest physicist of all time.
#1 is considered scientific because there is a test for proving it wrong. Scientific Hypotheses must be testable<br>
09
Science answers theoretical questions
Technology solves practical problems
Art creates objects that stimulate the senses
Religion deals with nature’s purpose
ALL AREAS ARE COMPLEMENTARY, NOT ANTAGONISTIC (against each other) Science, Technology, Art and Religion<br>
10
For EVERY physics problem solved this year, your answer should be rounded at the third number.
If the fourth number (that is not 0) is between 0 and 4, change the 4th number and all remaining numbers to 0. (if they are after the decimal, you can eliminate them)
If the fourth number is between 5 and 9, add 1 to the third number and change the fourth number on to zeros (or delete if after the decimal). Rounding Numbers<br>
11
Suppose you get the following answers to a physics problem.
23.4167823
Look at the fourth number (1)
1 is between 0 and 4 so delete the 1 and the remaining numbers
Your answer should be 23.4 Rounding Practice<br>
12
Suppose you get the following answers to a physics problem.
12,167,823
Look at the fourth number (6)
6 is between 5 and 9 so add 1 to the 1 and change the remaining numbers to zeros
Your answer should be 12,200,000 Rounding Practice<br>
13
Suppose you get the following answers to a physics problem.
.00012376543
Look at the fourth number not 0 (7)
7 is between 5 and 9 so add 1 to the 3 and delete the remaining numbers
Your answer should be .000124 Rounding Practice<br>
