*I agree, and that's why physics is the language of mathematics, it's
very good at describing things. An equation can describe how system X,
that is made of mass/energy, can in an interval of time change into
something different, system Y. But a language by itself can't do
anything because neither mathematics nor the English language can
change with time unless there is a brain made of atoms to think about
them. *
Language is representation. Its "energy" can't do work either. Its
"distance" isn't far away whatever you think about it. And mathematics
doesn't change just because you think about it.
*Neither intelligence nor consciousness can exist without something
changing with time. *
I think you're just making a philosophical position out of a tautology
change=>time. You might as well add motion=>distance and
heating=>temperature.*
*
*The symbols that make up mathematical equations can't change with time, *
They can't change with distance either, or the ink used, or motion,...
But their meaning changes in different applications.*
*
*but carbon atoms can, so you can erase a symbol in an equation that
you penciled in and lay down a different pattern of carbon atoms that
represents a different symbol.*
/> Occam suggests that we don't actually need reality to exist,
only the equations./
*Modern philosophers define "reality" as a substance that actually
exists in an external world, and they define "existence" as the state
of having "reality". And round and round we go.That's why I say in the
modern age it's mathematicians and physicists who are in the vanguard
of the investigation into the fundamental nature of reality, while
those who write "philosopher" on their tax forms when it asks about
occupation are really in the synonym business not the philosophy
business. *

*And I would also maintain that the semiconductor industry is an
existence proof that equations alone are not sufficient because they
can't DO anything. *
The existence of something that's not equations alone and does
something, is not a proof that nothing is done by equations alone. It's
a proof that at least one thing requires more than equations to be done. **
*If you want to actually DO something, that is to say if you want to
make a change over a period of time, then you're going to need
mass/energy.*
Actually those are conserved. What you need is low entropy energy.
