Not sure what this means in a math context. The north pole of the Riemann sphere is, in a sense, "the" point at infinity in the complex plane. So in t...

You answered the second question, not the first. If the potential of existence of rational beings is extinguished, would the potential of mathematics ...

If humanity were to vanish and the potential of rational beings extinguished, so would go the potentials of mathematics - or not? The potential of rat...

What if the purely "mechanical" act of measurement produces a numerical result that goes automatically into a computer file and is never "observed" as...

The entire quantum subject would be better served if "observer" were eliminated everywhere and replaced by "measurement". Then the casual physics dile...

Yes, the gun problem is intractable. On the other hand, for those of us in the middle class life is pretty good, despite stubborn inflation. When we g...

Real-life Q-physicists have been chased away, I fear. Kenosha Kid tried to get some sympathy for the Transactional approach, but had unsatisfactory ex...

A reflection . . . When I was in high school in the early 1950s I belonged to the NRA. I recall the American Rifleman being about target shooting and ...

I'm not sure my little exposition should be a reference point. That's how I perceive change over time. I can also go backwards in time, showing there ...

I'm with Victor Toth on this one. Gravity is a force. The force is counteracted by the upward force of the plane before the parachutist leaps away. Th...

Language of calculus. dV means "change in V", etc.

dV/dh=A is not abstract. If you measure a change in depth, then dV=Adh gives the corresponding change in volume. Suppose it were possible for that cha...

A good point. However, much of Q-theory presupposes spacetime in one or another metric framework. When you see d^4 in a formula that probably indicate...

It's nit-picking, but starting your lengthy presentation with an inaccurate statement can distract from your argument. The falling parachutist does no...

Possibly, but there are those in the immigrant community who are industrious and eager to succeed and choose the Republican Party because it tends to ...

I fear trying to correct a climate trajectory is a bit of a joke unless all on Earth work together diligently, taking away the comforts of civilized s...

An understatement of significant proportions. :roll:

, , Oh well, and here I was trying to follow an important dictum of philosophical dialogue I have learned of on TPF: Wrong, but interesting. :smile:

Reinforcements from several different sources helps. But look at the Ukraine/Russia War. How many Russian soldiers have died. One source may say 100,0...

I drive to Walmart to pick up my wife. She will either be standing at the door we agreed upon, or she will not (still shopping). When I get there, the...

I was thinking more along the lines of infinite causation chains and original causes. Sorry to interrupt.

From a certain mathematical perspective this is arguable.

:up: If being is interpreted as existence I agree. If being is the nature of a person, I might argue that that essence must involve consciousness.

Indeed it did. I'm 86 and things I haven't thought of in years come back to irritate. :meh: But so do good things. :smile:

And this could be a topic of discussion all by itself. It's interesting that a small incident that occurred years ago can pop up in our minds when we ...

I'm not sure what "problems in application" you refer to since in most applications - if not all - one works with rational or computable numbers. I ca...

Whoops. Sorry. My fault. :yikes:

Y= The town is entirely flooded by the river. X=River Drive is flooded. Go figure.

An impressive vocabulary. :smile: (Oh, forgot. What Aristotle thought about something.)

:up: :lol:

And that's why you're not a climber. You should try it. Might lead to an existential breakthrough. Can't hurt (since death is admirable). Look how doi...

Rather, getting to the edge of nowhere. Big difference. :cool:

(Zapffe) And yet he lived to the ripe old age of 90. Also, he was a noted climber, so his existential search was not unfruitful.

You are way above me, my friend. I never got over an infatuation with BASIC, merely dabbling in Fortran, C++, etc. Look at my icon. This little guy ma...

Me neither. Perhaps it's simply that we are born without meaning of existence somehow programmed into our brains, and yet a need for it, and must cons...

Perhaps space and time are not "actually quantized in real discrete units".

To find meaning in what one does or is, regardless of the degree of volition giving rise to the doing or being. As an example, you might be in the Arm...

Shadenfreude is one aspect.

Truth table

I love it when philosophers dabble in statistics. It's fun to visualize a group of academics sitting around a coffee table in the philosophy faculty l...

:rofl: .

Lots of mathematicians don't use the infinity symbol except in a limit sense. The idea of some entity called infinity existing doesn't normally crop u...

His last participation was about a year ago. He had made some comment about pursuing a "Pot of Gold" with his guitar. :cool:

Those who apply mathematics normally are not deeply conversant with its axiomatic structure. Most mathematicians - in the pure realm - are not either....

:up: However, this doesn't seem quite correct. One could argue that someone with MPD experiences just that. But, you might say, they shift from one to...

The truth table for that statement has him taking no chances.

Yes. You did mention him. I found some of his papers on researchgate.net, to which I also belong. This guy is older than me!! How can that be? I'm not...

This Article is intriguing. At first I thought they had found a way to reverse time in the quantum world, but rather they rejuvenated a photon, taking...

I must admit that in my old age one philosophical issue does interest me: where does the set of potentials created by a "new" concept or discovery res...

Looks like it could be 1/2. I used to teach stuff like this many years ago, but haven't indulged since. Could be 1/3 I guess. If you draw a diagram of...
