“Please keep your style: I really love it!” (Lang Lang, after I played Liszt’s Wild Hunt for him) Diplomas (from the Ecole Normale de Musique de Paris – Alfred Cortot): - Higher Concert Diploma (Diplôme Supérieur de Concertiste) - Pedagogy certificate (Certificat de Pédagogie) - Higher teaching diploma (Diplôme Supérieur d'Enseignement) For several years I have been giving piano lessons to children and adults, beginners (who have never played the piano) and advanced students (who want to study professionally). It is about learning a piece effectively and quickly, acquiring good technique, and understanding the theory. I value your goals and expectations, and I enjoy teaching! Prices (in 2024): - 3rd Prize in the international competition Pianissima international (Category: Prestissimo; Jury President: Cyprien Katsaris) - 3rd prize in the international competition Opus Artis - 2nd Prize in the Léopold Bellan Competition, special award for Rachmaninoff I've given several concerts in France, Belgium, and Greece. I've also performed on French television (France 5). I had the opportunity to audition for Lang Lang in a masterclass at the Salle Cortot in Paris; Lang Lang praised my performance of Liszt's Wild Hunt: "Please keep your style: I really love it!" I studied at the Ecole Normale de Musique de Paris – Alfred Cortot with Michael Wladkowski and Guigla Katsarava. I studied harmony and counterpoint with the composer Stéphane Delplace. Starting in September 2025, I will be studying with Zlata Chochieva at the Bern University of the Arts. I'm happy to answer any questions! Thierry

19FrIB Chemistry, Brief Lesson Outline: The Electromagnetic Spectrum
Trusted teacher: 🧪 IB Chemistry Apprentice Lesson Plan Topic: The Electromagnetic Spectrum Level: IB Year 1 (Apprentice) Duration: 60 minutes Lesson Objectives By the end of this lesson, students should be able to: ‣ Describe the electromagnetic spectrum and identify its different regions. ‣ Understand and apply the equation c = fλ. ‣ Differentiate between a continuous spectrum and a line spectrum. ‣ Explain the concept of quantized energy in atoms. Lesson Outline Introduction (0–5 minutes) Start the lesson by asking students a few engaging questions: What are some examples of invisible light or radiation around us? Why do we wear sunscreen? Allow brief responses, then explain that all of these examples are part of the electromagnetic spectrum, which we will study today. Teaching Phase 1 – Overview of the Electromagnetic Spectrum (5–15 minutes) Introduce the electromagnetic spectrum. Explain that it is a range of all electromagnetic waves, which vary by frequency and wavelength. Emphasize that all electromagnetic waves travel at the same speed in a vacuum – the speed of light, c = 3.00 × 108 m/s. Key formula to introduce: c = fλ, where: c = speed of light f = frequency (Hz) λ = wavelength (m) Point out that high-frequency waves have short wavelengths and higher energy (like gamma rays), while low-frequency waves have long wavelengths and lower energy (like radio waves). Display a spectrum diagram showing the range from radio to gamma rays, with visible light in the center. Teaching Phase 2 – Spectrum Types: Continuous vs. Line Spectrum (15–25 minutes) Explain the difference between continuous and line spectra. A continuous spectrum** contains all wavelengths in a range, like a rainbow produced when white light passes through a prism. A line spectrum** shows only specific wavelengths or frequencies. This happens when excited electrons fall back to lower energy levels and release photons of specific energies. Explain that energy is **quantized**—electrons cannot have just any amount of energy; only specific values are allowed. Use the helium line spectrum image as an example. Real-World Examples and Class Discussion (35–45 minutes) Give students three practical examples and discuss their uses: 1. Microwaves – Used in cooking and communications. 2. Ultraviolet (UV) rays – Cause sunburn; used in sterilizing equipment. 3. Gamma rays– Used in cancer treatment and in detecting radioactive materials. Ask students: Where do you see or use electromagnetic waves in your daily life? Encourage short contributions to reinforce understanding. Student Exercises (45–55 minutes) Have students complete these three questions individually: 1. A wave has a frequency of 6.0 × 1014 Hz. Calculate its wavelength using c = 3.00 × 108 m/s. 2. Explain the difference between a continuous and line spectrum, with an example of each. 3. Why are gamma rays more dangerous to humans than radio waves? Wrap-Up and Recap (55–60 minutes) Call on a few students to briefly summarize one key thing they learned.
