Olympiad preparation
Theory, timed problems and the data-analysis and observational rounds, for national olympiads and the IOAA.
Learn the universe you're made of.
Astronomy and astrophysics lessons from a working researcher — for olympiad students, exam students, university students and curious minds.
Lessons for every stage
Exam physics
Gravitation, light and spectra, stellar physics and cosmology for IB, AP, A-level and national exams.
University & Python
Intro astrophysics problem sets, plus Python for astronomy with real light curves, spectra and Astropy.
How it works
Book a 30-minute trial
Pick a time that suits you. You pay €20 when you book.
We set clear goals
Where you are, where you want to be, and a plan to get there.
Weekly lessons
Live simulations, practice problems and a notes summary after every lesson.
Free tools
Interactive, physics-based simulations — free to use in class.
Exoplanet transit
See how a planet's size and orbit shape a transit light curve.
Blackbody & HR diagram
Change a star's temperature and radius; watch its spectrum and place on the HR diagram.
Orbits & Kepler's laws
Stretch an orbit and see equal areas swept in equal times.
Questions
What does the €20 trial include?
The trial is a 30-minute lesson. We talk about where you are and where you want to get to, set clear goals, and then I teach a short segment so you can see how I explain things. There is one trial per student.
Which levels do you teach?
Four levels: Foundations (beginners, younger students and enthusiasts), Intermediate (school physics students), Advanced (strong school students and first-year university), and Olympiad & university (olympiad candidates and astrophysics courses, including Python for astronomy).
How do online lessons work?
Lessons are live video calls. We work on a shared online whiteboard, use the interactive simulations on this site to see the physics move, and solve problems together. After each lesson you get a short notes summary and a few practice problems.
