DHRicoF··on OK, I can partly explain the LLM chess weirdness now
I don't think there is enough (non syntetic) data available to get near what we are used to.

The big breakthrough of GPT was exactly that. You can train a model with (for what that time was) stupidly high amount of data and make it okis to a lot of task you haven't trained explicitly.

DHRicoF··on My NumPy year: Creating a DType for the next generation of scientific computing
One way in with address data sparcity is using arenas, a big pull of memory allocated where the strings lives, instead of them "floating" around all the heap.

the other improvements are related to the representation and layout of utf.

I've only read this briefly, so I don't know if there are other optimizations there in the memory allocation or anywhere.

DHRicoF··on Time is a dimension, but not like space
> Not just 99%, but 99.99999999% or however many you want.

Badly enough, even that's not true.

We have a frame of reference given by the cosmic microwave background. When you move faster and faster at some limiting speed will create pions that will slow down the particle creating an effective slower max speed.

Just like my code!

I think your comment lack a little deep.

Quantum mechanics describe the evolution of the state of system given the initial conditions and the hamiltonian describing it. That's exactly what the Schrodinger equation says and why it has a partial derivate of time. Usually in introductory treatments only the "time independent Schrödinger equation" is addressed, but that's a sub product on a common technique used to solve some family of differential equations.

In classical mechanics you can interpret time as another coordinate, but with so many privileges that it's a little far reached call it in the same way as space dimensions. Without the metric introduced in special relativity there is no way to justify put them in the same footing. For example, in classical mechanics you cannot rotate in a way that makes the time coordinate fall in a space coordinate, while you can do that in relativity, and it's called a boost.
