The Questions That Changed Mathematics

Negative numbers. Irrational numbers. Complex numbers. Each began with someone asking an impossible question. Today’s episode explores how curiosity has driven the greatest discoveries in mathematics—and how the same “What if?” mindset can transform our own lives.

The Most Interesting Subject

Mathematics has fascinated Dave for decades, but people have become his greatest teachers. Through mentoring, marriage, and mathematics, he reflects on how curiosity deepens relationships and helps us see stories hidden beneath the surface.

What If There’s a Better Way?

Coaching Actuaries began with a simple question: What if there was a better way to prepare students? Dave shares how curiosity led to innovation, reminding us that meaningful change often begins by questioning assumptions everyone else accepts.

Curiosity and Faith

When God invited Abraham to count the stars, He wasn’t testing arithmetic—He was expanding Abraham’s imagination. Dave reflects on how mathematics helped him understand that something can be both abstract and real, and why curiosity and faith belong together.

The Beginning of Hope

A small change in how Dave listened to people transformed his relationships—and his outlook on life. As the week concludes, he reflects on why curiosity is more than a personality trait. It’s a way of living that keeps us open to beauty, truth, and hope.

Is Uncertainty Built Into Reality?

What if uncertainty isn’t just part of life—but part of reality itself? Dave shares how an unexpected career disappointment led him from teaching mathematics to becoming an actuary, introducing the surprising role probability plays in helping us navigate an uncertain world with reasonable hope.

Living Without Guarantees

Insurance helps us manage uncertainty, but it cannot eliminate it. Dave explores how probability equips us to make wise decisions without guarantees and why faith gives us the courage to take the next step when certainty isn’t available.

The Wisdom of Stepping Back

Individual events are difficult to predict, but larger patterns often emerge when we step back. Dave explains one of the foundational ideas behind insurance and reflects on how a broader perspective can transform disappointment into perseverance.

Don’t Put All Your Eggs in One Basket

Diversification is more than an investment strategy—it’s a way of preparing for an uncertain future. Dave explores why resilience often comes not from predicting tomorrow, but from wisely preparing for many possible tomorrows.

When Randomness Creates Order

The Central Limit Theorem reveals how order can emerge from countless random events. Dave reflects on how life’s daily surprises can also reveal deeper personal patterns, inviting us to grow through honest reflection and trusted feedback.
