Computations
Scientists have borrowed a technique from applied mathematics to rapidly predict the behavior of fusion plasma at a much-reduced computational cost. (1) Trying to compute things. But we will never do that. Unless we use the whole universe. And have it standing still. Just computing things. We will then know it all. And right then…

Against AI.
The new artificial intelligence system ChatGPT has become a sensation. It can write poetry, it can program whatever you ask it to, it can reply to your answers. In summary, it can do whatever a human can do. Taking into account the fact that most humans have more limited knowledge than ChatGPT, it would be…

Dark AI… Dark humans…
A study found that hiring algorithms are too opaque for us to understand if they are fair or not. (1) In other news, a scientist tried to help humans design algorithms that would never go the wrong way, doing harm rather than good, by implementing fail safes in their initial design (2) We have started…

Chaos. Numbers. Simulations.
Digital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find scientists. The study, published today in Advanced Theory and Simulations, shows that digital computers cannot reliably reproduce the behaviour of 'chaotic systems' which are widespread. This fundamental limitation…
