Mathemagicians

Anyone can create
magic with math.

A free library that explains every concept properly, and small live courses for students who want to go further.

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. 40 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.
