The questions are still open!
Most physical theories were imagined abstractly before being (or not) validated, sometimes a long time after, by observations. Even today, explorations continue and propose new visions of our world, which will one day be confirmed or disproved. It is often daring mathematicians who have ventured into what is apparently not their territory, although the two disciplines were very close until the last century. Yet, who better than these adventurers of abstract concepts can uncover a hidden law? Among them, a woman, Emmy Noether, knew how to base a part of physics on the research and study of invariants, thus becoming a pioneer of modern mathematical physics. Some of David Hilbert's celebrated problems are also in connection with physics.

Quantum computers: a threat to encryption | Tangente
Internet communications are currently secured by symmetric encryption systems such as AES, whose keys are transmitted using an asymmetric encryption system such as RSA.
Cosmology and polyhedra: Plato to Kepler | Tangente
Regular polyhedra appear in many theories. These five solids fascinate us with their remarkable symmetries.
The unforgettable Emmy Noether
A strong-willed woman and visionary mathematician, Emmy Noether defied many restrictions throughout her life and opened up new fields in mathematics and physics.
Hilbert, the twenty-three problems and physics
In his plenary address at the second International Congress of Mathematicians in 1900, David Hilbert presented the world with his famous "twenty-three problems." Some relate directly to physics; others have driven advances in both physics and mathematics.
What if our universe were a hologram? | Tangente
Our universe could be a sphere whose exterior would resemble a black hole. Our world would merely be the reflection of a reality inscribed on the surface of this sphere—a kind of hologram. All information would be encoded on our cosmic horizon. A scenario that may not be so far-fetched after all…
Loop quantum gravity
What if our universe were actually discrete? If confirmed, a bold theory known as loop quantum gravity could reconcile the physics of macroscopic gravitational fields with quantum physics. Spin plays a fundamental role in this theory.
