Outlines
đż The Shower System and Balancing Feedback Loops
Paragraph 1 introduces the concept of systems through the mundane activity of taking a shower. Cynthia, part of a family system, prepares for dinner by showering using the heated water system in her house. The paragraph explains a system as a set of interconnected parts working towards a common goal, here, to deliver heated water. The shower's operation is detailed as a balancing feedback loop where Cynthia adjusts the water temperature based on her perception of the gap between the current and desired temperature. This loop includes a delay, representing the time it takes for the heated water to reach her. The concept of a 'stock' is introduced with the water tank and heater, which are part of the larger household water system. The paragraph also touches on how systems can extend beyond physical structures, like the traffic system affecting their friend Alex's arrival.
đ Traffic Jams and Reinforcing Feedback Loops
Paragraph 2 delves into the dynamics of traffic systems and social interactions, using Alex's experience in a traffic jam to illustrate reinforcing feedback loops. These loops, unlike balancing ones, push the system further from equilibrium, as seen with the escalating anger among drivers. The paragraph highlights how individual reactions can influence the collective behavior within a system. It also discusses the potential for information to alter system behavior, as Alex's stress eases upon learning the cause of the delay. The narrative then broadens to include the fishery system, where Marcel's choice of fish for dinner is just one small part of a larger ecological and economic system. The paragraph explores the impact of fishing practices on fish stocks and the challenges of managing such systems for sustainability. It concludes by connecting these various systemsâshower, traffic, fishery, and friendshipâto the simple act of enjoying a meal together, emphasizing the interconnectedness of all systems in our lives.

meet Marcel Cynthia and Kiki or rather
meet Marcel's circulatory system
Cynthia's nervous system and Kiki's
digestive system not only are these
three made of systems but they're also
part of systems like the family system
that connects them
together tonight Marcel and Cynthia are
PR preparing to host their good friend
Alex for dinner Cynthia worked all
afternoon in the garden and her basket
is full of freshly picked
vegetables now they need to get ready
Cynthia goes upstairs to take a shower
and Marcel heads to the kitchen to
cook Cynthia is still thinking about
those tasty peas she just harvested
she's certainly not thinking about
systems little does she know that she's
about to enter one right
[Music]
now a shower is a convenient way to
clean up but it's also a system we can
think of a system as a set of parts that
are connected to one another and
organized to achieve a certain goal in
this case the goal is to bring heated
water upstairs for Cynthia and Marcel to
use but watch what happens when Cynthia
goes to start her shower Cynthia herself
is a part of the shower system and her
feedback will help her get the
temperature just
right eventually every time Cynthia
adjusts the shower handle she brings the
temperature closer to where she wants
it while Cynthia is finally happy in the
shower here's a way of looking at the
system water is Flowing from the shower
head at a certain
temperature Cynthia knows what
temperature is ideal for her and the
nerve endings in her hand perceive a gap
between the current temperature and her
desired temperature which makes her turn
the handle to adjust the temperature of
the water closer to the level she wants
altogether these actions feed back into
each other in a loop that can be
repeated until the desired temperature
is
reached here's the same feedback loop
presented in a different
[Music]
way a feedback loop that is
self-correcting is called a balancing
feedback loop but why does it take so
long to get the temperature right well
that delay is part of the system too
the shower system continues from the
bathroom upstairs all the way down to
the water tank and the heater in the
basement and it takes time for the
heated water to travel through the
pipes because delays are important
forces in systems we better add one to
our feedback loop voila we place it here
to indicate that it takes time for the
temperature adjustment to result in a
change in the water temperature in this
shower system we also mentioned the
water tank and the heater the water in
the tank is a good example of a stock a
quantity that can grow over time as a
result of an inflow and can decrease
over time as a result of an
outflow so the stock of water in the
tank receives an inflow of cold water
and releases an outflow of heated water
for Cynthia to
use Marcel in the kitchen is also
drawing from the stock of hot water as
he washes some
fishes the shower system is just one
part of The house's larger water system
but systems extend far beyond water or
the house at that very moment Marcel
gets a call from Alex he's on his way
but stuck in traffic something is
causing a major backup on the roads Alex
has driven this route a 100 times
without DeLay So what's going on well
there's been an accident on the highway
that's slowing everything down normally
cars would be flowing through the
highway smoothly but today they're at a
standstill cars keep entering the
traffic jam from the back but no one can
move until the accident is cleared up
the outflow in this system is all
blocked and it looks like Alex might
just have to wait it out unfortunately
it seems that no one is very patient at
this time of day trying to get home for
dinner someone in a car nearby honks his
horn now that no one is moving
a social system has been added to the
traffic system and Alex is on
edge the woman behind him keeps trying
to nudge her car up even though there
isn't any extra
room Alex is getting more and more tense
and so are the drivers around him the
whole thing is quickly escalating into
quite a mess why is everybody getting
angrier well just like Cynthia
responding to the temperature of her
shower the people in this traffic system
are responding to one another in a
feedback loop but rather than bringing
the system into balance they're driving
it further and further to the
extreme as Alex's anger increases his
expressions of anger make other drivers
around him
angrier and when angrier their
expressions of anger escalate into a
frenzy of gestures and offensive words
that make Alex angrier here's the same
feedback loop present it in a different
way this type of feedback loop is called
reinforcing because it gains strength at
each
cycle but back in the traffic jam
something is
happening luckily just as things are
threatening to get out of hand a traffic
sign lights up with details about the
delay
now that he knows what's going on and
has some information to plan with Alex
starts to relax he imagines new
additions to the transportation system
to speed things up and avoid
traffic a well-trained raptor to the
rescue or a more feasible Light Rail
could do the trick how pleasant it would
be to step on a train and be able to
bypass the highway entirely
and finally the traffic starts moving
again phew surely that transportation
system was complicated enough for one
night right well not exactly back at the
house Marcel proudly shows Cynthia the
fish he picked out at the fish market
earlier today but purchasing a fish is
only one very small part of the fishery
system that Marcel is now a part of this
seemingly simple entree where did it
come from Marcel's fish started out in
the ocean as part of a school of
fish the school is itself a system and
like the shower and the traffic system
it has flows new fish flow into the
school as fish reproduce and fish flow
out because of fishing predators and
because of natural deaths if the
outflows Matched the inflow of new fish
the fish population would stay fairly
stable that would be a healthy fishery
but as it turns out Marcel isn't the
only one who enjoys a nice fish filet
now and then demand for fish is high
fishing is increasing and the stock of
fish is
shrinking There are rules in place to
try to protect the fish schools
fishermen can only fish for a certain
part of the year the fish they take must
be a certain minimum
size and any individual can Harvest only
so many fish but the people who made
those rules had only imperfect
information on how many fish are left
and they may have been thinking more of
today's economic returns than the
long-term health of the fish stocks the
system has been set up to deplete
itself in a system designed to maintain
a healthy stock of fish in the long
term would Marcel have been able to
afford that fish he bought would there
be that species of fish for sale at all
of course none of these complexities are
on Marcel's mind he sets the table he's
just happy that the fish is ready and
looking
tasty Cynthia feels refreshed from her
shower and Alex finally pulls into the
driveway to join them they all sit down
to enjoy a nice meal together while
they're lost in the evening's delicious
food and pleasant company it's easier to
see the systems that made it all
possible the house is water system the
neighborhood's transportation
system the nation's fishery system and
many many more including the system of
friendship that binds these three
together
