The Foucault Pendulum

And the Myth of Stillness

In 1851, a French physicist named Léon Foucault suspended a massive pendulum from the dome of the Panthéon in Paris. It swung back and forth, quietly, majestically.

But over time, something strange happened. The direction of its swing began to shift, not because the pendulum changed, but because the Earth underneath it was turning.

This was one of the first public demonstrations that the Earth rotates. Without a textbook or a telescope but through a swinging weight in a church.

The Foucault Pendulum is elegant because it reveals a deep truth without saying a word. The motion of the pendulum doesn’t lie. It keeps swinging in the same plane, while the world turns underneath.

Sometimes, you feel like that pendulum. You’re doing what you know, moving with rhythm, purpose, grace. But the ground beneath you is shifting. People around you change. Expectations evolve. Cultures transform. You wonder why things feel out of place and you blame yourself.

But that’s not on you.

I say this because I’ve felt that. Especially when I had short stints in jobs where I thought I was building a long-term career. I had to explain it to recruiters. To parents. To mentors. They asked, Why so soon? And I had to say it wasn’t me, my ambition or impatience but situations. It was about the ground shifting. A new boss. Existing toxic boss. A funding freeze. Office culture. Internal politics that derailed the business plan.

It’s hard to believe but not every job switch is about a bigger paycheck. Sometimes, you leave because the current orbit has collapsed. Because the environment changed, not you. And yet, we carry this strange stigma that short stints look bad on a CV. That stability is defined by how long you stay, not by whether you had the wisdom to leave when it no longer made sense.

That’s flawed thinking.

We think of stability as something static. But true stability is dynamic. It means knowing when to adjust, when to lean in, when to pivot. The pendulum can’t stop the Earth from turning. But it can reveal that movement is always happening, even when you feel still.

The real mistake isn’t swinging. It’s ignoring the rotation beneath your feet.

In science, the Foucault Pendulum became a quiet revolution. It told a story we had ignored: that stillness is often an illusion, that the world is never truly fixed.

And maybe that’s the point. You don’t need to fight the rotation. You just need to recognize it. Adapt your swing. Change your tempo. Stay in motion, but with awareness.

The question isn’t just: Am I doing the right thing?
The real question is: Has the world around me shifted while I wasn’t looking?

Because clarity doesn’t always come from staying longer. Sometimes, it comes from knowing when the rhythm no longer matches the motion of the world.

I used this picture because it visually represents distortion through clarity. The glass of water bends and reshapes the face behind it, just as our experiences can be refracted by shifting environments.

The person hasn’t changed, but the view of them has. This mirrors the Foucault Pendulum idea: the swing stays true, but the world moves beneath it. It’s about recognizing when perception shifts not because you’ve lost direction, but because the ground has moved.
