Systems/Box Theory Flashcards
what two aspects make up scale
- temporal scale
- physical scale
two types of system feedbacks
- direct relationship
- inverse relationshihp
inverse relationship system feedback
the value of one parameter tends to decrease as the value of the other parameter in the relationship increases.
direct relationship system feedback
both variables increase together or both decrease together
is this a direct or inverse relationship
inverse
is this a direct or inverse relationship
direct
quantification
linkage of physical and conceptual models together
what can quantification ascertain
how things change
true or false
systems theory is a rational subdivision of a complex world
TRUE
true or false
systems theory stresses relationships
true
true or false
systems theory decreases the likelihood that all relevant variables are included
false
true or false
systems theory discourages quantification
false
systems theory assists with making
decision and predictions
the overall goal of natural models is to
assist in prediction
how does black box become grey box
through research
levels of the box theory
- black
- grey
- white
black box
understand inputs and outputs but NOT the interactions between or the variables
what don’t we understand with black box
the interactions between or the variables
example of a black box
we know a cow becomes a hot dog, but HOW?
grey box
understand inputs and outputs and SOME of the interactions happening
example of grey box
rainfall has lots of different interactions before it becomes run off. We understand some of those
white box
understand inputs, outputs and ALL interactions
what is important in box theory
scale
what depicts whether a system is a black, grey or white box
our understanding
when is box system often used
in modelling to simplify a system
what is important for understanding how things change
perspective
does nature need people
NO
what was the highest authority of land before today
CHURCH
plato’s theory of knowing
within truth and belief lies knowledge
true or false
belief is SEPARATE from truth and knowledge
TRUE
examples of what was deemed impossible but ISN’T
- analyzing stars
- heavier-than-air flight
- harnessing nuclear energy
- continental drift
why was the theory of continental drift rejected at the time
there was no mechanism proposed for WHY it happens
what makes matter
stars
true or false
all the molecules that make up humans come from stars
TRUE
is progress and time a LINEAR relationship
NO
examples of what could DRIVE progress to increase
- making money
- curiosity
- survival and war
- competition
what can cause progress to decrease
information and misinformation
knowledge should be seen as a
circle
why is knowledge seen as a circle
as you progress in life, you gain more and more knowledge until we find a speciality
what makes a circle of knowledge a bit bigger
PH.D
true or false
is explaining knowledge difficult
YES
