What if one look could change everything?
There’s a quantum physics experiment that blows my mind every time I tell it: the double slit experiment.
Here’s how it works: When a beam of atoms passes through two tiny slits, it doesn’t behave like a stream of particles. Instead, it acts like a wave, spreading out, overlapping and interfering with itself. The result? A beautiful pattern of light and dark stripes on a screen—like the light is dancing with itself.
But here’s the twist: If you try to observe which slit the light goes through, the pattern disappears. The wave becomes a particle. The light chooses a path: the mere act of watching changes the outcome. I say it again: the mere act of watching changes the outcome, yes!
It’s as if the atoms knew they were being watched—and changed their behaviour accordingly.
What does this have to do with your presentations?
Everything. We often design presentations by focusing on content: what we want to say, how we want to say it and in what order. We aim for clarity, impact and structure.
But here’s what we forget: A message only takes shape when someone receives it.
Your audience isn’t passive. Like the observer in the experiment, their presence, attention, and emotional response shape the way your message lands.
A great presentation isn’t just a fixed sequence of slides and ideas. It’s a field of possibilities. And it only collapses into meaning when someone’s eyes and mind are on it.
A great presentation isn’t just a fixed sequence of slides and ideas. It’s a field of possibilities. And it only collapses into meaning when someone’s eyes and mind are on it.
Just like in the double slit experiment, where a photon behaves differently depending on whether it's observed, your content behaves differently depending on who’s receiving it and how.
That’s because storytelling isn’t static. It’s not something you deliver. It’s something you co-create, moment by moment, with your audience.
Every nod, every glance, every shift in body language gives you feedback. It’s not just about transmitting a message: it’s about sensing the invisible field between you and the people in the room. That’s where the real story takes shape.
And this field is fragile. If it’s overloaded with information, it collapses into confusion. If it’s too scripted, it resists interaction. If it ignores the observer, it misses the chance to resonate.
This is why the best presenters don’t just “know their slides.” They read the room. They adjust the rhythm, the tone, the pause not to control the outcome, but to tune into the energy that’s already there.
In a way, your audience isn’t just watching your presentation. They’re shaping it.
So the question is: Are you leaving space for that to happen? Or are you closing the slits before the light has a chance to play?
Quantum-Inspired tips for designing impactful presentations
1. Design for connection, not just transmission.
You’re not delivering data: you’re opening a space for meaning to emerge. Each slide should anticipate not just what you're saying, but how it will land emotionally. Think of every slide as a relational moment, a doorway to empathy, surprise, or clarity. Ask yourself: What do I want them to feel here? What do I want to light up in their mind? Because communication is not a monologue. It’s an entanglement.
2. Leave space for the wave.
In quantum physics, waves can only form and travel when there’s space to do so. In your presentation, space is not empty; it’s potential. Use silence strategically. Let a powerful image breathe. Give key ideas room to echo before you move on. Don’t fill every pixel and second. Because meaning often hides in the in-between, in the pause after the metaphor, in the breath before the reveal.
3. Remember: every gaze is different.
Just like particles react differently when observed, your presentation shifts depending on who is in front of you. What works in one room may fall flat in another—not because your content is wrong, but because the observer matters. Bring flexibility into your delivery. Feel the energy. Adjust the pace. Sometimes resonance is not in the words you planned, but in the presence you bring. You’re not just presenting—you’re co-creating an experience that only exists here and now, with this specific audience.
A presentation is never static. It’s never entirely yours. It’s light shaped by the eye that sees it.
And yes, sometimes, one look really can change everything.
