Re-Film
We chose our background as plain so we could capture the ball bounce better and added horizontal lines within the backing to measure the distance between each bounce.
Captured a strange collision between the hockey ball and the ping pong ball.
The double bounce in mid air is definitely something I would like to work on.
May rotoscope the footage as ping pong because of the foreshortening.
Gravitantional Acceleration
In physics, gravitational acceleration is the acceleration on an object caused by gravity. Neglecting friction such as air resistance, all small bodies accelerate in a gravitational field at the same rate relative to the center of mass.[1] This equality is true regardless of the masses or compositions of the bodies. At different points on Earth, objects fall with an acceleration between 9.78 and 9.82 m/s2 depending on latitude, with a conventional standard value of exactly 9.80665 m/s2 (approx. 32.174 ft/s2). Objects with low densities do not accelerate as rapidly due to buoyancy and air resistance.

Heavy Ball
The camera is still shaky and didn't capture the drop point.
Filming needs to be re-done.

Bouncy Ball Project
Footage was shaky and camera was at a slant. Ball was hard to capture.

Algoriths + Computer Programs
Siso C++
Start with general abstract.
What is algorithms? Algorithms is step by step operations.
How many problems are in one operation?
The remainder of an integer division (A mod B ) Algorithm
1) Read two numbers A & B
2) If A is smaller then B go to step 5)
3) Replace A by A-B
4) If A is greater or equal to B go to step 3)
5) End, the result is A
100BC = Algorithm
You can have an Algorithm in another Algorithm.
Toy Story 3
MAYA IS AN ALGORITHM
Describing objects in space, textures etc. All are algorithms.
Same algorithms can get similar results.
Algoritms make decisions for you.
Lord of the Rings - use a massive program - integrate character with live footage.
Could have an algorithm better than James Cameron? Naaa
Complicated algoritms when your speaking to a computer. One that plays chess?
When does the algorithm stop? Limitation?
Worked on enigma - Allan Turnis - Committed suicide? for being gay!!
Damn Gordon Brown -Kill

A Turin Machine
You don't need to know the algorithm, just need to know the device.
Black box that can move left and right.
[||||||||||||||||||]
---------------------------------^------------------------------- <<TAPE

Black box can move left and right
The Turing Machine Code
Left
Symbol
on the type
internal state
gears etc
Right
When the black box does
3 symbols
Black box moves left to right one box at a time
00 = > 00R
01 = > 11R
10 = > 01L.Stop
11 = > 11R
Algorithm - can be expressed through machine ecident by ractical idea, operation of turing machines
Turing Machine modify tape 0 - 1
Input 000001110000 < if you don't turn internal state turn right
Output 0000011110000
00 => 00R -Move to right
001=> 11R (Bold are marks on tape) Change the state to 1 and skip right. skip all the ones until you find the next 0
Have one internal state modify tape :s
10 => 01L Stop. Stop to the left. Move left.
All the ones on the right are your results.
You only need to know the devices. Mechanical. It takes a well defined device, operations and stick with those can express any algorithm at all!
Algorithm & Computers
You need a language to express computers.
Don't want programming using turing language.
Programming language are turing type operation.
Cane be decimal formats - low level language
Turing machine is a language
Binary Decimal - describe variables
Higher level language - still basic numbers
A Programming language
C++ Python - higher level language
Computer Hardware and Von Neumann
Processor lets you read memory - Intelligent
Sketch of the Von Neumann Architecture - Similar to turin machine
The register can gold tempo-mental information in the tape
Read data and write data
Can create a turing machine that executes any...?
Taxanomy - If you were to write the native processor writing programmes as 0701s
Assembly range - internal processor, same as machine, simple selection of commands.
Higher Level programmes that organise data
Machine Language looks like binary numbers
Load Value - One >> Particular address to storage
Add Value - Two >> " "
Store Sum
Higher Level Language
Sum - Value_one + Value_two -stores particular memory.
