Are you saying the Natural numbers are
A) not countable
B) not infinite
Are you aware that this is your own position that basically no one holds? — CaZaNOx
Yes the countable numbers are countable. — tim wood
I just don't see how you can equate the process of counting with the claim that there will be an end to the counting or not. — CaZaNOx
On Youtube are a number of videos by Fermilab in which are covered a lot of interesting topics including several on relativity. The idea is that (your) distance contracts as measured by someone in motion relative to you. To you, in your system, no contraction. It's all not-so-simple and requires attention to how relativistic ideas are expressed. The casual - intuitive - idea can be suggestive and descriptive, but often is also completely wrong.In Einstein's theories, as you approach the speed of light, distance contracts. — petrichor

A laser beam through a completely empty space, with no dust, gas, or any such thing, would be invisible. — petrichor
If Bob in a ship is moving relative to me at close to the speed of light, his ship will be length-contracted. — petrichor
hmm, but wouldn't that mean that stars are invisible from a spaceship? what dust is there in outer space to de/reflect the sun's or other stars light? — TheArchitectOfTheGods
As you measure it. — tim wood
If Bob in a ship is moving relative to me at close to the speed of light, his ship will be length-contracted. — petrichor
But Bob will think he's at rest and that you're length contracted. — tim wood
If, for example, you were correct, the length of Bob's yardstick as measured by Bob (moving East to West) would vary depending on if he were measuring in the E-W direction or in the N-S direction. (And Bob would then be able to measure his velocity simply by twirling a stick.) — tim wood
They both in their own reference frames measure their own yardsticks at a true yard. But each measures the other's as contracted. — tim wood
The nature of consciousness just isn't very clear and to think of it as an epiphenomenon of the brain same as bile secreted by the liver is falling short... — Anthony
It's as though our eyes project images as well as receive them, don't ask me how (the information is both out there and in the brain at once, as it were). — Anthony
In some way, what is seen is really out there where it seems to be and not solely a representation in the brain. — Anthony
I feel confident in saying that nobody understands consciousness. That includes scientists, materialist philosophers, idealist philosophers, dualists, spiritualists, Buddhists, Hindus, Protestants, New Agers, neuroscientists, psychologists, cognitive scientists, AI researchers, Daniel Dennett, Deepak Chopra, and all the rest! Nobody has a friggin clue. — petrichor
I would modify this statement by saying that if nobody understands consciousness then they don't understand materialism, physicalism and empiricism either. — Joshs
Maybe some of these things are just what they are and can't be understood in terms of anything. Maybe we reach the end of the line. Maybe, in experiencing the flow of time, in its immediate qualities, we grasp all that there is to grasp, and trying to relate it to a river or something gets us further away from the direct experience of it and further from understanding what it is. Maybe you can't get deeper than that. — petrichor
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
