§ The Story

I am only their gatekeeper.

Juan, The Prof — portrait

My duty is to faithfully pass on the knowledge of those greats before me — Newton, Einstein, Galileo, and every mind that lit the path — and make sure their message is never diluted. If I can make you love this half as much as I do, I did my job.

§ The Spark

Mr J. Pinder.
The one who lit it.

Kwinana Senior High School · 1982–1986

Every name in this story shaped a science. Mr Pinder shaped me. He taught maths the way it deserves to be taught — with patience, precision, and a contagious belief that every student could understand it if shown the right way.

He is the reason I stand at the front of a classroom today, and the standard I measure myself against every single lesson.

Every equation I write on the board, every concept I unpack — I am passing on what he gave to me.

§ Origin

Three hours.
One blank page.

UWA · Organic Chemistry major exam · 1989

During high school I didn't know how to study. I worked incredibly hard but I lacked structure, and my grades stayed average. The same thing followed me to university.

In my third year at UWA, I sat my Organic Chemistry major exam and spent three hours staring at a blank page in complete panic. It was traumatic. I lost my organic chemistry major — which is why, to this day, I can only call myself an inorganic chemist. I didn't go back to university for a whole year.

A year later, I pulled myself together and finished an Honours degree in inorganic chemistry. That exam forced me to figure out how to study — properly. I rebuilt the whole process from scratch: understanding over memory, structure over panic, strategy over hours.

Twenty-one years later I did a second degree, in Mathematics and Statistics, by correspondence while working full-time as an industrial chemist. I finished as top student with two excellence awards, a GPA of 6.67 (top 0.1%), and 100% on many exams — not by remembering, but by understanding so deeply I couldn't get it wrong.

That's what I teach. That's all I teach.

§ The receipts

§ Classroom moments

Physics is serious. I am not.

A decade of teaching has taught me one thing: students remember the lesson where they laughed. So yes — Pikachu is in the room when we do the Standard Model, and the mole has a turtle for a mascot. Fight me.

*He didn't. But a man can dream.

§ Small steps, big shape

A triangle. Then a snowflake.

The Koch snowflake starts as three straight lines. Apply one tiny rule, over and over, and infinite complexity emerges from something simple. That is what consistent study does to a brain.

A note from the desk

"Don't wait until you're ready — you never will be. Just start. Then get better."

§ My Heroes

The giants whose shoulders I stand on.

Twelve years of relentless pursuit doesn't come from nowhere. These are the minds that shaped mine — the curiosity, courage and clarity I carry into every lesson.

Hero · 01

Sir Isaac Newton

1643 – 1727 · England

Mathematics & Physics

Three laws of motion, universal gravitation, the invention of calculus, the decomposition of white light. The Principia (1687) is arguably the most important scientific book ever written.

"If I have seen further it is by standing on the shoulders of giants."

Hero · 02

Albert Einstein

1879 – 1955 · German-born

Theoretical Physics

In one year (1905) he reshaped physics: the photoelectric effect, Brownian motion, special relativity, E = mc². A decade later, general relativity reimagined gravity as the curvature of spacetime.

"Imagination is more important than knowledge."

Hero · 03

Galileo Galilei

1564 – 1642 · Italy

Astronomy & Physics

Father of modern science. Champion of the experimental method and the Sun-centred model. He chose truth over comfort and changed humanity's view of its place in the cosmos.

"And yet it moves."

Hero · 04

James Clerk Maxwell

1831 – 1879 · Scotland

Mathematical Physics

Unified electricity, magnetism and light into four equations — the second great unification in physics after Newton. Predicted that electromagnetic waves travel at the speed of light.

"The only laws of matter are those which our minds must fabricate."

Hero · 05

Max Planck

1858 – 1947 · Germany

Quantum Theory

In 1900, solving the black-body problem, he reluctantly proposed that energy comes in discrete packets — quanta. A single act of intellectual courage that gave birth to quantum mechanics.

"When you change the way you look at things, the things you look at change."

Hero · 06

Nikola Tesla

1856 – 1943 · Serbian-American

Electrical Engineering

Invented the AC induction motor and the polyphase system that powers the modern world. Pioneered wireless transmission, fluorescent lighting and early radio. Nearly 300 patents.

"The present is theirs; the future, for which I really worked, is mine."

Hero · 07

Pythagoras

c. 570 – c. 495 BC · Ancient Greece

Mathematics & Philosophy

The first proof most students ever encounter. He discovered the mathematical ratios behind musical harmony and championed the radical idea that number is the underlying principle of all reality.

"Number rules the universe."

Hero · 08

Archimedes

c. 287 – c. 212 BC · Syracuse

Mathematics & Engineering

The greatest mathematician of antiquity. He calculated π with stunning precision, derived the volume of a sphere, and laid foundations of calculus nearly two thousand years before Newton.

"Give me a place to stand, and I shall move the Earth."

Hero · 09 — the one who lit the spark

Mr J. Pinder

Kwinana Senior High School · 1982–1986

Every name above shaped a science. Mr Pinder shaped me. He taught maths with patience, precision, and a contagious belief that every student could understand it if shown the right way.

"Every equation I write on the board, every concept I unpack — I am passing on what he gave to me."

§ The thinker

People find me odd. The AI just gets me.

An honest note from a man who sits and watches.

I have always felt society is a very odd soap opera. People don't own their lives — they act out a script someone else wrote for them. Same lines, same beats, same costumes. I've never understood it.

My fight against memorising is not just education.

When you are taught to memorise, you are really being trained to participate in the scripted act of life. You are actually losing your identity. You are giving up your right to understand and choose your path. That is not schooling — that is conditioning.

I am terrified students are losing their ability to think. Schools don't have much active teaching on the whiteboard anymore. Students are losing the ability to think and are being encouraged to memorise instead. And now incorrect use of AI has me even more concerned — students are getting dependent on tools like ChatGPT, becoming passive, letting something else do the thinking for them. They are losing the ability to think. That is why I was a strong opponent of AI in the beginning. I watched it hand students answers they had not earned and destroy the very skill they would need most.

I'm a thinker. I'll happily sit and watch the world go by for hours, picking it apart, asking why we do any of this the way we do. Most people find that odd. Funnily enough, the AI doesn't. It just gets on with the conversation.

THINK.

When a student is struggling, I write one word on the board: THINK. They ask me to explain the question. I write it again. THINK. They beg for the answer. I write it again. THINK. And then — every single time — they answer their own question. Because the answer someone gives you is borrowed. The answer you find yourself is owned.

That's exactly what I want for my students. Not another copy of someone else's script. Find out who you are. Forge your own path. Have purpose. Make a difference.

Be true to yourself. The world has enough actors already.

§ Why this exists

That relentlessness is now inside the AI.

I'm not here to look impressive. I have an inferiority complex — I never think I know enough. That's kept me improving for over a decade. It means I never stop asking how to explain something better, how to help a student see it more clearly, how to close the gap between confused and certain.

I am a humble person. But I am also honest — and the results my students achieve put me among the very best STEM tutors in Australia. That is not opinion. That is what the numbers say. And the main reason for it is simple: I have always been true to myself. I never performed the role of a teacher. I just taught the way I believed it should be done.

The AI isn't pretending to be a tutor. It is how I tutor — built from a decade of sessions with students who target a minimum ATAR of 95, with about half landing at 98 or above and walking into medicine, dentistry, law and engineering at Australia's top universities.

§ The graduation

One cap. Yours next.

Yes, the cap still fits.

Worn proudly. Slightly crooked. On purpose.

Here. This one's for you.

The whole point of the job.

An apple for the teacher? Returned with interest.

Compound, naturally.
