PeroK replied to the thread AI vs. Humans as Processors in an Environment.History tells a different story. Look at the life expectancy of a slave on a sugar plantation. Or, the wholesale slaughter in WWI. The... -
PeroK reacted to jack action's post in the thread AI vs. Humans as Processors in an Environment with
Skeptical.
The only way the rich get richer is by exploiting people working for them for nothing. People dying or getting sick means the rich lose... -
Quantum physics raises measurement as central. And possibly fundamental. Not "matter"(whatever it is). Or energy. They come later.
-
Energy is not the ability to do work in quantum physics but the property to change how states change over time. Measurement gives...
-
It is VERY far off, and one need only very basic understanding of physics to see that. Energy has a very specific definition (do you...

PeroK replied to the thread Undergrad What is matter?.Colour is a property of paint. But colour is a property of other things as well. Energy is not exclusively a property of matter. It can...
-
PeroK replied to the thread Undergrad What is matter?.Mass and energy are properties of matter (and of antimatter). Matter also has charge, spin and other properties, like colour charge etc.
-
I would have said: matter is simply condensed energy. You might run into minor problems with this defintion because of energy-mass...

PeroK reacted to FactChecker's post in the thread Undergrad The natural numbers and logical consequences of them with
Like.
That is where "infinity" begins. It is the size of the smallest infinite set. It's size is denoted by ##\aleph_0##. There are larger... -
PeroK reacted to tech99's post in the thread Undergrad Our Mathematical Universe book -- Since when does light contain voltage? with Like.
If I place an electric circuit, containing a suitable indicator, in the path of an EM wave I can notice a current being created.

PeroK reacted to Ibix's post in the thread High School A question on the geometry of black holes with Like.
No. If you fell into a black hole the mass of the Sun (and if GR were correct which it probably isn't!) you would reach the singularity...

PeroK replied to the thread AI vs. Humans as Processors in an Environment.It seems valid to me to see AI as potentially in direct competition to humans, in all respects. It's ironic that it requires continued...

PeroK replied to the thread High School A question on the geometry of black holes.It's not like that. A singularity is when a mathematical model breaks down. It's not a physical thing. Once you cross the event horizon...

PeroK reacted to Ibix's post in the thread High School A question on the geometry of black holes with Like.
You can't extend that kind of picture to a black hole interior, unfortunately. Assumptions made during the drawing fail at the event...

PeroK replied to the thread Undergrad The natural numbers and logical consequences of them.The natural numbers form a countably infinite set. You can partition the natural numbers into a finite collection of infinite sets. E.g...
