Big doors swing on little hinges


“Big doors swing on little hinges” is a common metaphor used to describe the goal of quantum health.

Last year, when explaining quantum health, I used this colloquial definition quite a bit.

At that time, I was especially interested in understanding redox, which can be thought of as the balance of:

  • oxidative vs antioxidant forces
  • positive vs negative charges
  • protons vs electrons
  • acid vs alkaline

(yes, these are all different ways of exploring very similar concepts)

What would Planck say about quantum biology?

I think Planck, the founder of quantum physics, would challenge many of these new ideas coming out of the interdisciplinary inquiries of quantum mechanics and biology—at least initially—because that’s what he did in life when people built upon his concepts.

But, ultimately, I think he would be glad to find his work being applied to concrete problems and mysteries in that field.

I also don’t think he would outright curse the more “woo” directions the word quantum is simultaneously going.

In his own words:

"As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent spirit [orig. geist]. This spirit is the matrix of all matter."
~Max Planck

Hi Reader, I just finished getting the replay of my recent Quantum Breastfeeding class up and out to everyone who signed up to attend live. I sent the link out to everyone who attended (email me if you can’t find it), and it’s also inside the membership at Brighter Days, Darker Nights (flash sale now). If you’re not in either of those groups, you can get it a la carte below. Quantum Breastfeeding Replay The class ended up lasting about 2 full hours, and all the goodness is included in the...

WHAT'S NEW 1-1 SUBSTACK INSTAGRAM BOOK (coming soon!) Breastfeeding is both ancient and ever-evolving in the face of new influences like artificial light, EMFs, and EDCs. I find it fascinating that breast milk is a circadian signal, and that nurturing maternal rhythms improves the milk. It can be rich with melatonin, endocannabinoids, and other rhythms shaped by light and season. Yet under-supply, oversupply, and supplementation remain confusing in today’s modern environments. This live class...

Many, many people have been asking for more guidance around breastfeeding and wondering if a quantum approach could help them resolve their challenges. So, I am putting on a class to share how to use quantum supports others may be overlooking. Quantum Breastfeeding The class is for both parents and practitioners and will take place live on October 16th, 2025 at 1:00 PM Pacific / 4 PM Eastern. It is free for all paid subscribers of my Substack, and guest tickets are available for $25 (includes...
