Creating Models from Scratch

- Dartmouth College, Hanover, New Hampshire, Spring of 1977. In this lecture, Donella Meadows has a lively discussion with her students at Dartmouth College as they create a model to express the relationship between epidemic diseases and mosquitoes. Donella engages with her students and reminds them that they can make models however they want. Models never express the full complexity of real systems; they will always have some simplification.

Her timeliness is simply impressive. This channel deserves a Nobel Prize!
She was so lovely and caring human being...
I'm so glad I have a privilege to learn from her thought process and facilitation.
Thank you so much for making this available to us.
***Really interesting but need to start watching at***
Nice first principles discussion of understanding and creating a model of how an infection spreads in a population (epidemic model).
1. 06:55 Discusses how to make and educated guess at drawing out a graph of infections and deaths for an infectious disease.
2. 10:46 Class discussion that develops on blackboard a simple causal diagram and model of yellow fever, mosquitos, vulnerable uninfected people, infected people, people who die from infection and wider environmental factors e.g. weather.
3. 30:00 More detailed formal model that includes delay times i.e. incubation periods. Developed by the teacher/lecturer, Donella, outside of the class.
4. 33:37 DYNAMO more realistic graphs of infected population and. Deaths over time.
5. 34:20 Explanation of the equations used in the DYNAMO model that the teacher/lecturer has developed outside of class.
TBH, this's really fun, I hope I have chance to sit in and interact with the professor. Thank you for sharing this course for free. 🙏🙏
Excellent professor!
The students really get engaged, I wish I had that, in my classes people are on their phones or watching the professor looking bored af
Yeah... this era really, really... change us..
Total hero of mine. A gateway to many different subjects. Electronic Oracle is an underrated classic. That said; is it just me or is there a hint of Princess Leia in that 1977 look she's sporting?
nah i have the same feeling of her looks
Start around 6:38 if you want to skip the initial discussion of the Dynamo CLIP function (though that has some interesting discussion of policy formulation).
Thank you
very clear
This should be taught / explained to school kids at an early stage!
The future generations are the product of overshoot and torchbearers of Collapse.
She did a great favor to humanity ...
Am a mechanical engineer in construction and I have recently discovered SD and am studying it for the sole reason of teaching it to my son as he grows up and integrating it into his learning
Genius.
Is there another lecture available with Donella talking more in-depth about using random variables in SD models?
Her voice really reminds me of Amy Adams
General behavior I dont need accurate numbers
Population is the keyword :
YES WE CAN 2016 - 2116 is an encouragement for mankind to save a sustainable biosphere on earth by a free decision for OneChildPolicy. To reduce worldpopulation from 7.4 Billion in 2016 to the tolerable size of TWO Billion (2x10^9) according to ecological research e. g. Donella and Dennis Meadows ('Beyond the Limits'), Stanford- University of California (Biologist Paul R. Ehrlich, 'The Population Bomb') and the BertTheAce Research-Institute for Ecology (Foundation, 'World Biosphere') we need FOUR Generations (100 years) of OneChildPolicy worldwide on a free decision. If we succeed with worldwide OCP for the coming 100 years, mankind has a good chance to reach a balance between consumption of natural resources, pollution and recovery of a sustainable biosphere for thousands of generations.......and isn't the care for our biosphere on earth a better option for mankind, than to try to escape to Mars, who did already loose his biosphere ?
HISTORY will CONFIRM BertTheAce and his MASTERPLAN
'YES WE CAN 2016 - 2116'

I came here to learn how to scratchbuild models and learned how to kill deer.
