Episode 20: Tesla's Current--The Mind of a Visionary

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.

Episode 19: The Pull of the Invisible

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 magnetic fields and the Earth’s magnetic shield

  • Thoughts on spiritual alignment, energetic pull, and emotional repulsion

  • A journal prompt to help you reflect on what’s quietly guiding you right now

Episode 18: The Nature of Light – Particle, Wave, and Metaphor

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 mirror for your own nature — something radiant, reflective, and full of paradox?

✨ Featuring:

  • A simple explanation of light’s duality in quantum physics

  • Spiritual insights on the symbolism of light across traditions

  • A journal prompt to guide self-reflection and inner clarity

📝 Reflection Prompt:
Where are you being asked to shine more brightly in your life?

Episode 17: Summer Soulstice

The Sun is at its peak. The longest day of the year is here—and with it, a powerful invitation to pause. 🌻
⠀
In this new episode of The Interested Reader, we explore the science and symbolism of the Summer Solstice:
☀️ Why the Sun appears to “stand still”
☀️ What ancient traditions saw in this seasonal threshold
☀️ How to use this moment to reflect, realign, and recharge
Let the Sun inspire you. Let the stillness guide you.✨ PLUS: Get a FREE Solstice Reflection Journal when you subscribe to The Interested Reader newsletter! It's a gentle guide to help you connect with the light—inside and out.
⠀
✨ ☀️ ✨ ☀️I posed a few questions for meditation or journaling:

1. What in your life is coming to full bloom?

2. What needs to be illuminated right now?

3. Where are you being invited to pause and realign?

4. What do you need to honor before the light begins to wane again?

✨ When you're finished changing, you're finished.

Episode 14: Numerology

What's your number?


Turns out there's a few, and we'll find out what they are. In this episode we'll take a closer look at numerology (known once upon a time as arithmancy) -- its history, the methods, and a few examples.


I've always loved numerology, but studying it now has given me a few new insights into myself. I hope you discover something new and exciting as we take this journey.


We'll also learn what's going on in the skies this month, from a Beaver Moon to meteor showers.

Episode 9: Sound Effects Part 2

In this second of a two-part series on sound effects, we'll take a look at the healing power of music, from ancient Greece to modern times. Have you ever wondered a lyre sounds like? Or an ancient Greek aulos? Tune in to this episode and we'll find out!


Can sound heal physical ailments? Can it levitate multi-ton slabs of stone? Was it used to build the Great Pyramids?


Get ready to take some musical notes as we journey to the center of the soul (which the ancient Greeks said could be healed with music.)


Consider this quotation from Albert Einstein:

Concerning matter, we have been all wrong. What we have called matter is energy, whose vibration has been so lowered as to be perceptible to the senses. There is no matter.

Episode 7: DNA Phantom Effect

Are genes particles or waves? Does our DNA leave an imprint in a source field? Today we'll discuss the answers to these questions as we take a look at wave genetics, the DNA phantom effect and how sound waves have been used to heal.

Come with me, and let's take an orderly walk in 1 dimension at constant acceleration, into the phantom world of energy fields.


Notes from the show:

  • Equations of motion in the x-direction
  • One of my favorite books, where I first read about the DNA phantom effect:

The Source Field Investigations, by David Wilcock

  • Dr. Peter Garyaev: The Institute of Linguistics of Wave Genetics
  • Paper, Crisis in Life Sciences. The Wave Genetics Response, Garyaev et al.
  • Visible images of phantom effect
  • PCR Amplification of phantom DNA (requires PDF download)

A quote from Dr. Peter Garyaev:

“In particular, we have found it possible to regenerate endocrine glands in animals. By the same means, we have significantly curbed the aging process in human cells and even grown new adult human teeth in individuals who had lost them.”        ~ Peter Gariaev  https://www.fractal.org/Life-Science-Technology/Peter-Gariaev.htm

Episode 6: Scalar Energy Part 2

In this episode, we continue our discussion about scalar energy. Last time we talked about the definition of scalar waves and the principle of quantum entanglement. This time we'll talk about scalar energy as it pertains to consciousness and healing.

Are our thoughts scalar waves? Can scalar waves interact with our physical bodies? Can we show that scalar waves exist?

Let's take a random walk and find out!

Episode 5: Scalar Energy Part 1

In this week's episode we'll talk about some basics of mathematical notation and get an introduction to vectors and scalars. Then we'll take a closer look at scalar fields and the wild world of scalar energy.

In this first of a two-part series, our discussion about scalar energy will be about gaining a working knowledge of definitions and vocabulary. We'll gain an understanding of what is meant by "scalar energy" and "quantum entanglement."

This is one of my favorite topics and I can't wait to take a quantum leap with you into a world of "spooky action at a distance."

Check out these websites that I reference in this episode:
