The Cosmic Classroom
Welcome to The Cosmic Classroom, where space science meets simplicity. Each episode breaks down big cosmic ideas into small, meaningful lessons you can share at home — no telescope required. You’ll learn fun, easy-to-understand ways to explore space together while building your child’s curiosity and your own confidence along the way. I want to ignite your passion for exploring and questioning. Not only that, but I want to show you how much fun it can be to learn science! Because here, it’s a simple equation: Space Science + Simple Lessons = Endless Enjoyment.

Episode 20: Tesla's Current--The Mind of a Visionary 20.08.2025 1:19:49
Nikola Tesla was more than an inventor — he was a visionary who believed the Universe spoke in energy, frequency, and vibration. In this episode, we explore Tesla’s groundbreaking work with magnetism and alternating current, his astonishing ability to “see” inventions fully formed before building them, and the spiritual insights that guided his creativity. 📥 Download your free companion journal h...
Episode 19: The Pull of the Invisible 30.07.2025 45:00
Magnetism is more than a force—it’s a language of attraction, alignment, and invisible influence. In this episode, we explore what magnetism really is, how it shapes the physical world, and how it can serve as a metaphor for the inner pull we all experience. Tune in for a journey through physics, self-reflection, and the unseen currents that shape our lives. Includes: A quick explanation of magnet...
Episode 18: The Nature of Light – Particle, Wave, and Metaphor 15.07.2025 49:40
Light is one of the most mysterious and powerful forces in the Universe — and in our lives. In this episode, we explore the dual nature of light in physics: how it acts as both a particle and a wave, defying simple definition. Then we shift into the metaphorical and spiritual realm — asking what light represents in our inner world, how we shine, and what it means to reflect. 💡 Could light be a mi...
Episode 17: Summer Soulstice 18.06.2025 36:20
