There were attempts to make decimal computers using voltage from 1~10v for example.

The problem happens on fluctuations, electricity being lost through wires, problems with energy escaping... And this can cause big problems of a 10 of the CPU becoming an 8 until reaches the GPU. If your part receives a 9.3v, it's a 9 that gained voltage along the current, or it's a 10 that lost it? Or an 8 that gained much more?

Binary is easy because "if there are ANY energy here, it's an 1. Otherwise, 0."

Far more reliable, electromagnetic interferes very little, error detection and correction are far more easy.

I'm just trying to wrap my mind around this... It's 2am, so please give some slack:

Can we consider that Earth is "accelerating"/spinning referent to the sun, because it's rotating around the sun? And the sun around the galaxy? And the galaxy around some center of mass of local group?

Because as far as I understand, the same "rotation" movement is done from the surface of the Earth to its center of mass, as a simple orbit from Earth to the sun.

So calculate the real time/speed of something really far, like another galaxy, can become very tricky because we are accelerating in many different referentials

Or I'm making mistakes with different concepts here?

Nice one. I thought that she was picking poisonous flowers and putting them in some place that would contaminate the water or something like that, killing people unintentionally
