- Math is all around us, from the patterns in nature to the algorithms in our technology.
- The study of mathematics can help us better understand the world and make sense of complex systems.
- Mathematics is more than just numbers and equations; it is a language that can be used to express complex ideas.
- By breaking down complex concepts into simpler parts, we can understand even the most advanced mathematical theories.
- Math can be fun and exciting, and everyone has the potential to enjoy and learn from it.

- "Is there a word that means both interesting and fun? Math is that word."
- "Mathematicians are like Frenchmen: whatever you say to them, they translate it into their own language, and forthwith it is something entirely different."
- "When a mathematician says something is trivial, it probably isn't."
- "Mathematics is like checkers in being suitable for the young, not too difficult, amusing, and without peril to the state."
- "Calculus, the mathematical study of continuous change, underpins many of the greatest advancements of modern science, from planetary orbits to electromagnetism, and everything in between. It's also a subject that makes most students want to retch."

- "We like to think of our lives as orderly, predictable, and comprehensible. But the truth is more likely to be this: our lives are constantly shaped and reshaped by chance events."
- "We take for granted our ability to see in the dark, but it's really an incredible feat of computation and signal processing."
- "Mathematics is an art, and as such affords the pleasures which all the arts afford."
- "Like maps and music, the equations are a way of making an abstract world tangible, of giving it form and substance."
- "Mathematics is the art of explanation. If you deny students the opportunity to engage in this activity – to pose their own problems, make their own conjectures and discoveries, to be wrong, to be creatively frustrated, to have an inspiration, and to cobble together their own explanations and proofs – you deny them mathematics itself."

- The debate over the value of pure versus applied mathematics, and whether mathematics should be viewed as a tool or as a creative art form.
- The challenge of making mathematics accessible and engaging for all students, including those who may not be naturally inclined towards the subject.
- The tension between the deterministic nature of mathematical models and the inherent unpredictability of many real-world phenomena, such as weather patterns and economic markets.
- The ethical considerations of using mathematical models to make decisions that affect human lives, such as in the case of algorithmic decision-making in criminal justice or lending.
- The question of whether mathematics is a universal language that could be used to communicate with extraterrestrial life.

- The small-world phenomenon, popularized by Strogatz's research with Duncan Watts, shows how even in a large population with weak ties, individuals can be connected in a few steps through a "friend of a friend" network.
- Benoit Mandelbrot's discovery of fractals and the concept of self-similarity, which helped describe natural patterns like coastlines and mountains.
- The discovery of the irrational numbers by Pythagoras and Hippasus, which shattered the belief that all numbers could be expressed as a ratio of integers.
- The number theory work of Andrew Wiles, who proved Fermat's Last Theorem after 358 years of being unsolved.
- The use of game theory in economics by John Nash, whose life and work were portrayed in the movie A Beautiful Mind.
