What are we looking for
Data ≠ Knowledge
Our knowledge is based on experience, on data we collect
But raw data is meaningless
We use data and thinking to build models
Then we test if the models make correct predictions
Models allow us to
- Reason
- Explain
- Design
- Communicate
- Act
- Predict
- Explore

Basic
Circles, boxes, arrows
- Circles represent things
- Boxes represent processes that change things
- Arrows show the inputs and outputs of process
Basic
T consumes one A and one B to produce one C
Dogma
Something wrong here
This diagram has a problem:
- Transcription process does not destroy DNA
- Translation destroys RNA to make a protein
- Not true, but a good approximation
Correct dogma
Simple model, with correct balance of mass
How would you complete it?
- Draw it with pen and paper
Cell growth
names do not matter
A
B
Cell growth
position of circles and boxes does not matter
Two systems, one model
(A)
(B)
PCR
If the models have the same arrows, they will have the same behavior
