What is Physics? I, II, III

don't click. . .I dare you!
Gary Zukav's, The Dancing WuLi Masters


Physics is the art of discovering the patterns in nature.
We have a wonderful opportunity to understand her mostly subtle,
often deep mysteries, if we focus our gaze, listen intently and
analyze her incredible signals.

Physics does not belong to Physicists!

Does reading the text help us understand what Physics is all about?

A Scientific Theory

A Scientific Theory is a proclamation supported by an abundance of observational evidence from nature and the remarkable ability to make accurate predictions of future natural phenomena. Examples of scientific theories include the Special and General Theory of Relativity, Atomic Theory of Matter, Quantum Theory,
The Theory (Law) of Evolution, Plate Tectonic Theory and The Big Bang Theory.

A proclamation that does not support all the observational evidence and cannot be used to provide accurate predictions is an idea or speculation. Examples of ideas that are not theories are String Model of Matter, Ptolemaic Model of the Solar System, Lamarkian Evolution and The Hole in the Earth.”

Time (seconds)

Mass (kilograms)


We are on the hunt for the Higgs Boson. . .maybe then, we will know mass!
Time is everyone's guess. . .

Distance to the nearest 7-11 is in the bag. . .but to the nearest Galaxy?

We will get back to these fundamental units. . .again.
Right now, let's pretend we got a handle on them.

Significant Figures. . .are important!!

The use of significant figures in our measurements are very important.

For example; I say I am 6 feet tall.
Is this correct?
Sure, to one sig fig! But, I am really not being honest.
I am really 5'7''.
This too, is not exactly correct, if I measure my height with a tape measure, I can get as close as 5'6.75''! You see, I am exaggerating my height because I feel small!
Sig. figs. are important. They tell us what the best measurement is at any certain time.You can't arbitrarily use as many sig. figs as you want!

Adding two or more Vectors

Realize that we can move the two vectors
any where we like, as long as we maintain
the vector's magnitudes and directions.

Place the two vectors at the origin
of a coordinate axis system.

Decompose the two vectors into their
respective x and y components.

Add the x-components of the two vectors,
this will be the x-component of the resultant vector.

Add the y- components of the two vectors,
this will be the y-component of the resultant vector.

Find the magnitude of the resultant vector
by using the pythagorean theorem.

Find the direction of the resultant vector
by using the inverse tangent of the
angle between the two vectors.
