Mathemagicians

Most people were never taught to think with mathematics. They were taught to perform it.

There is a difference between knowing a formula and understanding why it is true. Between following steps and seeing what the steps are actually doing. Between solving the problem on page 47 — because you have practised problems exactly like it — and solving a problem you have never seen before, because you understand the principle underneath.

Most mathematics education produces the first kind of student: one who can perform the familiar, and freezes when the unfamiliar arrives. That is not a failure of intelligence. It is a failure of method.

Anyone can create magic with math.

A magician understands a principle so deeply that what they do looks impossible to those who don’t. Every mathematician, physicist, chemist and economist is a magician in exactly this sense — not because they are rare, but because they were taught to see.

The philosophy

Build intuition before formulas

A student should feel a concept before naming it. The formula arrives as a relief — a short name for something the student already understands.

Practise through real problems

Abstract drill trains performance. Real problems build thinking.

Teach the reasoning, not the recipe

Reasoning solves problems nobody has written a recipe for yet.

Embrace productive struggle

Confusion before clarity is not a problem to be solved. It is the learning itself.

How we teach

Every concept, explained properly.

Mathematics, Physics, Chemistry and Economics, from the first steps to university. Each lecture takes one idea and explains why it is true, where it comes from and how to use it, with diagrams you can move and questions that check you as you go.

No account, no payment, no catch. 80 lectures are ready to read today, and new ones are added every week.

Two doors. One goes wide, one goes deep.

Every live course is taught by me, online, to a small group. A group opens when four students are ready, and each course is paid for once, with nothing further to pay.

One-to-one, occasionally. $70 an hour, a few places a year. Write to me.

I have been helping students qualify for competitive examinations in India for fifteen years. I have taught students in Thailand, Canada, the USA and Singapore, across every board from IGCSE to the IB Diploma to engineering mathematics.

If you are finding a subject tough, it does not mean the subject is tough. It means you have not yet met a teacher who loves it.

Tell me the student’s year and what they think about the subject right now. I will tell you honestly which course is worth their time, or whether none of them is.
