Do the Math! channel — my public channel for sharing mathematics with a broader audience.
When I think about why we should talk about math more to the general public than in an academic setting, I’m reminded of the case of André Rieu.
Rieu is a world-famous violinist and conductor, but what made him remarkable was not simply his technical mastery of classical music. It was the way he broke down the barriers around it. He took what many thought was elite, inaccessible, reserved for concert halls and conservatories—and he played it for everyone. He made it sparkle. He turned music into joy, into dance, into something that welcomed rather than excluded. And in doing so, he brought classical music to millions who might otherwise never have touched it.
That is what inspires me here. Because if Rieu could popularize classical music—not by cheapening it, but by letting its beauty shine for everyone—then mathematics, too, deserves to be opened in this way.
So let’s ask: why do a “for-everyone” channel about math?
This is a two-fold question. The better way to put it is this:
Question one, why does math need to be communicated to those who do not study math?
And question two, why is it important for people who do study math to try to communicate it—for their own good?
The answer to the first question is this: math is BUILT for everyone. In some sense, it is just like the arts, or even the sacred books of religions. The arts—whether it’s movies, paintings, or music—are intriguing because they appeal to everyone emotionally, no matter how distinct our personal experiences are. And the sacred books, like the Bible or the Buddhist scriptures, are fascinating because no matter what language you speak, and whether you believe in the religion or not, those books can still bring inspiration and provoke thought.
So if we say the arts are the universal stimulant of emotions for the senses, and if we say the sacred books are the universal carriers of enlightenment for the soul, then mathematics is the universal language of reason for the mind. Every one of us is born with logical intuitions, an innate rationality that does not need to be taught—what Kant referred to as knowledge a priori.
That is why the vast population needs math. Just like music charms your senses even if you never play an instrument or learn music theory, just like sacred books culture your soul even if you never enter a church or recite a prayer, math can please the mind even if you never dream of becoming a professional in the field.
It is deeply satisfying to make reasonable sense of the world. The world is not perfect, but people are built to ask why. We are built to look into the future and to analyze the past with our gifted rationality. Math, and logic, are the language for doing so. They are the path by which we can touch the world and say: it makes sense to me, in a beautiful way. Just like how your favorite song pleases your ears.
That is the answer to the first question.
Now the second: why should mathematicians themselves communicate math?
Math needs to be landed in reality to realize its full value. Humans live in flesh, and we learn through sensory experience. If we build perfect models and equations but never look at them from the perspective of someone in the physical world, then we are separating our intellect from our body. Math is a language for expressing reason, a platform to train and explore rationality, but it should also be a way of interpreting the world and interpreting ourselves—a way of turning experience into structured knowledge.
When we put math into context, we solidify our reason with experiential feedback, and that feedback only makes it stronger. And communicating math to the general public is the way of doing this. When we try to be the bridge that connects theory and reality, we also build that bridge inside ourselves—the bridge that unites our mind and body into one.
This is not just charity or service. It is also nourishment for the mathematician. When you explain math, you must see it in new lights—metaphor, application, even misunderstanding. Each encounter stretches your imagination and deepens your grasp. Communication is self-training. It is the test of whether your bridge can actually hold weight.
As famously proved by Gödel, math itself is unable to reach the full form of truth. If we only see it as an attempt to reach veritas, we’ve already lost our way. God does not teach us by throwing truth at us like lightning bolts. As limited as we are as humans, we could not learn that way anyway. Instead, He taught us by granting us senses to feel, an intellect to ponder, and a soul to love. He taught us by creating a world where He can meet us in flesh.
Math, then, should not be our attempt to elevate ourselves away from this world. It should be our way of using our gift to see that the world itself is a revelation.
That is why math belongs to everyone. And that is why mathematicians, too, need to share it. Because in that sharing, math ceases to be a tower of ivory and becomes what it was always meant to be: a public square, alive with reason, alive with beauty, alive with us.
And here, I think again of André Rieu. He didn’t strip classical music of its dignity—he revealed its joy to the world. In the same way, math does not lose its rigor when it is shared widely. On the contrary, it gains life, it gains resonance, it gains people. Just as he turned concert halls into dance floors, we can turn symbols and theorems into bridges of wonder for everyone.
That is the motive. That is the vision.
Math, like music, is too beautiful to be hidden away.
