MIT 1700 Lecture Notes 01/23/2012
MTC
input channel
output channel
Noise
There is a limit to how much information we can absorb
MTC developed in the 1940’s
Device
A
Alphabet”
B
Alphabet”: Any sense of communication shared by a sender and a receiver
Binary code between server and website
Morse code
Sign language
When information decays: entropy
it’s everywhere
Organizing your house and over time having it get messy again
A unary device will only give a single response no matter what happens
Information must produce some surprise
Magic 8-Ball
Binary device
20 possible responses
(10 affirmative, 5 negative, 5 neutral)
~ 72 tries to get all 20
Noise
Requires reduction, achieved through redundancy
information is copy and repeated in the event that it is intercepted by noise
noise is the enemy of information
Noise is coming from us, inside our head
We don’t hear 50% off the noise coming from our environment because we’re always thinking
Noise may equal freedom, but not fidelity
The universe wants entropy
1000 megabytes of information sent every year
The current amount of information we have worldwide would take 60,000 years of high quality dvd to
watch
90% of all that information was produced in the last 30 years
Cybernetics
Norbert Wiener
Founder of cybernetics
“Information wants to be free!”
Negative feedback stalls entropy
Bodies and machines operate similarly
