If so, that would help explain some mysterious things about math.

luiy's insight:


....... but there is one area of human endeavor that comes close to exemplifying the maxim “manuscripts don’t burn.” That area is mathematics. If Pythagoras had not lived, or if his work had been destroyed, someone else eventually would have discovered the same Pythagorean theorem. Moreover, this theorem means the same thing to everyone today as it meant 2,500 years ago, and will mean the same thing to everyone a thousand years from now — no matter what advances occur in technology or what new evidence emerges. Mathematical knowledge is unlike any other knowledge. Its truths are objective, necessary and timeless.

 

What kinds of things are mathematical entities and theorems, that they are knowable in this way? Do they exist somewhere, a set of immaterial objects in the enchanted gardens of the Platonic world, waiting to be discovered? Or are they mere creations of the human mind?

 

----------------------------------------

 

Indeed, there may be. In a recent paper, “Constraints on the Universe as a Numerical Simulation,” the physicists Silas R. Beane, Zohreh Davoudi and Martin J. Savage outline a possible method for detecting that our world is actually a computer simulation. Physicists have been creating their own computer simulations of the forces of nature for years — on a tiny scale, the size of an atomic nucleus. They use a three-dimensional grid to model a little chunk of the universe; then they run the program to see what happens. This way, they have been able to simulate the motion and collisions of elementary particles.

Bizarre, isn't it?

 

And, at the crux of it, is a mixture of how our brains interpret this reality and receive it, in addition to what's actually out there.

 

Perhaps we are a simulation of a universe, that is trying to understand and make sense of itself?

 

A vast computer program trying to uncover information about itself and other possibilities?

 

Think about it.

luiy's insight:

Algorithmes, éminences grises de nos vies connectées 


Trouver le signal dans le bruit est au cœur d’un nouveau changement de paradigme dans l’univers de plus en plus complexe de la consommation de médias.


Depuis une dizaine d’années, les réseaux sociaux, nos communautés, ont ajouté une couche de personnalisation, de partage et de recommandations à la consommation classique. Mais aujourd’hui vivre, c’est aussi générer des données ! De nouveaux services automatisés, les algorithmes, prennent le relais des intermédiaires dans la prescription des choix.


L’époque est aux « Big Data », qu’aucun humain n’est capable aujourd’hui de classer manuellement. L’intelligence artificielle transforme ce contexte en information. Les algorithmes traitent à très grande vitesse, voire en temps réel, les quantités gigantesques de données que nous produisons tous chaque jour, lorsque nous naviguons, recherchons, cliquons, échangeons. Ils exploitent de vastes bases de données dans le « cloud », pour mieux comprendre qui nous sommes et ce que nous voulons.
