Very true! But definitely a much more complex system to digitally replicate. There is also a big project to create a DT of Earth. That would probably be a great way to model climate and other challenges to preserve our planet destination-earth.eu

Yes, that’s the idea. Of course not all testing can be done on the DT but some can and then you need to possibly “destroy” less real airplanes in the testing process

My understanding is if we can do a really good one we can cut costs and,most importantly, waste less material in testing certain structures (like airplanes). Like in this project caelestis-project.eu
Plus a bunch of other things I guess

Unless you cut ties completely (rare).
So the move to industry?
It’s not an event.
It’s a second-order phase transition.
/end 🧵

That’s how leaving academia feels.
Your contract ends, but projects linger: papers to revise, collaborations to close, responsibilities to hand over.
The “order parameter” (number of open projects) decreases bit by bit.
It approaches zero… but never suddenly.

Phase transitions (like liquid water freezing into ice) are classified by how an order parameter changes
First-order = abrupt
Like water → ice: symmetry shifts all at once
Second-order = gradual
Like cooling a paramagnet into a ferromagnet: magnetization builds up slowly as temperature drops 🧪⚛️

I was also unsure of what I saw for a moment but the shape was clearly that of a soliton, so I did some digging to double check it good happen in open waters too. Glad you found it enlightening!

Finally someone as excited as I was!

And yes, my family looked at me weird when I excitedly told them about my sighting. Hope someone here shares my excitement 😁

No pictures (sadly), but a lot of excitement — and a story about how physics shows up when you least expect it.

Usually, solitons show up in canals or rivers where the conditions are “just right.”
That’s why I was so surprised to see a pair in the open waters of Skopelos gulf.

The first soliton was spotted in 1834 by John Scott Russell, who chased one on horseback for 2 miles!
He called it a “Wave of Translation.”

Solitons are fascinating because they behave unlike ordinary waves:
👉 they keep their shape
👉 they don’t fade away
👉 they can even split into pairs of from trains

Yesterday in Skopelos, the sea outside the harbor was so rough that no ships came in all day.
But inside the gulf, I saw two smooth, solitary waves traveling without losing their shape.

That’s the signature of a soliton.

Not fully up to me unfortunately

Anyway, stay tuned for the physics breakdown while the OA fee drama hopefully sorts itself out 😅⚛️

And honestly… why is no one talking about this?
I am sure I am not the only one transitioning to industry while projects are still pending and whose collaborators cannot cover OA fees alone!
