Systems and Mathematics
The Great Mental Models Volume 3 by Rhiannon Beaubien and Rosie Leizrowice introduces more powerful ideas to enhance critical thinking. It teaches how to create models that accurately represent complex concepts and train the brain to think more effectively.
Imagine you have a toolbox – but it only has a hammer in it. That’s going to come in handy when you need to pound a nail. But what about when you need to tighten a bolt? A hammer won’t be much use; in that situation, what you need is a wrench.
Your knowledge toolbox works in the same way. Everyone uses a set of mental tools – also known as mental models – to understand the world. But each model is useful for different problems and situations. The best way to improve the quality of your thinking is to broaden your repertoire of mental models.
The key message here is: The more mental models you can grasp, the better your problem-solving skills will be.
The world is incredibly complex. It constantly presents the human mind with overwhelming amounts of information. Mental models are tools for simplifying all of that data into organized portions that you can mentally digest.
Most people stick to a specific set of mental models – usually from their given discipline. If you’re a psychologist, you’ll probably think in terms of incentives. If you’re a biologist, you’ll think in terms of evolution. If you’re an engineer, you’ll think in terms of systems. All of these models are useful because they’re durable representations of how the world works; they won’t ever change.
But, as we’ve seen, not all tools are useful for all problems. It’s only by combining models that you can broaden your perspective and look at one problem from multiple angles. This way, you’ll be more adept at making decisions that can generate positive changes.
In the following blinks, we’ll draw on wisdom from models of systems thinking and mathematics in particular. Systems exist everywhere in the world, and they play an important role in your day-to-day life. Mathematics, too, serves to explain much of how the world works, using patterns of logic. The two disciplines are largely interconnected – just as the models themselves.
These disciplines might sound abstract at first. But by breaking each one down, you’ll see that the models have practical – as well as metaphorical – applications across daily behaviors and interactions. Meanwhile, the more you reflect on your use of individual mental models, the better you’ll be able to identify which ones are best for a given situation.
Let’s dive in.
The Great Mental Models Volume 3 (2021) is the third book in a series that shows how mental models from various disciplines can be applied to make positive changes to your life. This volume focuses on mental models from systems and mathematics. It demonstrates how you can use cognitive tools to improve everything from decision-making and relationships to healthy eating and personal productivity.
Ich bin begeistert. Ich liebe Bücher aber durch zwei kleine Kinder komme ich einfach nicht zum Lesen. Und ja, viele Bücher haben viel bla bla und die Quintessenz ist eigentlich ein Bruchteil.
Genau dafür ist Blinkist total genial! Es wird auf das Wesentliche reduziert, die Blinks sind gut verständlich, gut zusammengefasst und auch hörbar! Das ist super. 80 Euro für ein ganzes Jahr klingt viel, aber dafür unbegrenzt Zugriff auf 3000 Bücher. Und dieses Wissen und die Zeitersparnis ist unbezahlbar.
Extrem empfehlenswert. Statt sinnlos im Facebook zu scrollen höre ich jetzt täglich zwischen 3-4 "Bücher". Bei manchen wird schnelle klar, dass der Kauf unnötig ist, da schon das wichtigste zusammen gefasst wurde..bei anderen macht es Lust doch das Buch selbständig zu lesen. Wirklich toll
Einer der besten, bequemsten und sinnvollsten Apps die auf ein Handy gehören. Jeden morgen 15-20 Minuten für die eigene Weiterbildung/Entwicklung oder Wissen.
Viele tolle Bücher, auf deren Kernaussagen reduziert- präzise und ansprechend zusammengefasst. Endlich habe ich das Gefühl, Zeit für Bücher zu finden, für die ich sonst keine Zeit habe.
Hol dir mit Blinkist die besten Erkenntnisse aus mehr als 7.000 Sachbüchern und Podcasts. In 15 Minuten lesen oder anhören!
