I'm confused by your post. You make the correct point that the math is just a model of reality, not reality itself. Then you say that the thing DOES h...
Can you explain this to @"Metaphysician Undercover" and @Ryan whose handle doesn't show up when you use the @ button? But actually it's a good questio...
Ok. I can live with that. Whether it's a moving arrow or a current driving the speedometer, it's a change occurring over a short interval of time. But...
I'll accept this point. It still has nothing to do with what I originally said, which is that you don't need calculus to determine the instantaneous v...
The posterior probability that the world exists is 1. Whether that's a satisfactory response to the conundrum you raise, I can't say. Consider. Flip a...
Not for the first time I'm sure. Yeah yeah. One of Zeno's complaints. If you look at the arrow at a particular instant it's not moving. How does it kn...
What do you think speedometers measure? I take your point about instantaneous motion, it's related to one of Zeno's paradoxes. If the arrow is not mov...
A cursory search shows that I can't find it used anywhere. "Today I learned!" Oh -- L and R. Nice. I thought iterated functions were getting a lot of ...
Right, that's the answer to "does the square root of -1 exist?" Just as the number 5 can be interpreted as stretching a line segment by five units; an...
On the contrary, I have too much time on my hands. I've been over active on this forum lately and I'm feeling the need for a break. I think my reactin...
A quarter counterclockwise turn in the plane. That's the simple meaning. I was probably too harsh with my criticism of her video though, it's an excel...
Jeez man it's an analog computer. It gives a direct measurement of a physical quantity. You're saying there's no such thing as velocity. Your scientif...
I'll take a run at your graphs when I get a chance. You went to some trouble to draw them, you deserve a response. I agree that I don't understand you...
Funny you should mention that, since it's so easily disproven. Consider the speedometer in your car. How do you suppose it works? Is there a tiny litt...
Just my opinion, I didn't want to give you a hard time for posting it, she's always worth watching. That particular video annoyed me but as you know I...
I love her videos and articles but felt that she entirely missed the meaning of complex numbers in that video. When physicists talk about math it's al...
@Ryan claims that we should poll everyone in the world; I claim we should poll the professional mathematicians; and you claim we should poll the philo...
It was wrong of me to poke fun at you without responding to your last two lengthy posts to me. Fact is I wouldn't know where to start so it's better f...
I haven't been able to understand Ryan's approach. As in Apocalypse Now, when Kurtz asks, "Are my methods unsound?" And Willard responds: "I don't see...
Pi only encodes a finite amount of information. \displaystyle \pi = 4 \sum_{k = 0}^\infty \frac{(-1)^k}{2k + 1}. That's 16 characters if I counted rig...
If you're a cisgender straight guy and you prefer not to date a male-to-female transgender, you're a transphobe. That's the word from the SJW playbook...
I don't understand your idea at all. Suppose the position of a particle at time t is given by f(t) = t^3 - 5 t^2 + 9t - 6. Find the acceleration of th...
Second clause does not follow from the first. A mathematical line is composed of points. But there is no "next" point after any given point. You are c...
Not sure what you mean. Mathematical points on a line are represented as real numbers; mathematical points in n-space are represented as ordered n-tup...
This isn't the time or place to discuss Wildberger's crankitude and I'll leave you to your research. FWIW he's one of two PhD-level math cranks I know...
You're right, he's a professor of math and he puts his ideas out there under his own name, and the likes of me throws rocks from behind my anonymous h...
I'm not the only one, Google around. And FWIW, I'm a crankologist. I enjoy reading math cranks and am familiar with the work of most of the prominent ...
In your professional research, did you have the feeling that you were investigating aspects of truths outside yourself that you were trying to find ou...
I do not believe any scientist has proposed the physical existence of such a thing. For one thing, in physics we know that our theories break down at ...
I addressed this in my post. The position and velocity functions are not differentiable at time zero. So there's no well-defined acceleration. Nor as ...
Where do they live? And what else lives there? The baby Jesus? The Flying Spaghetti Monster? Pegasus the flying horse? Platonism is untenable. There i...
If I point out to @"Metaphysician Undercover" that he can get in his car and drive to the store without being crushed before he drives the first inch;...
Ahhhhh, so we shouldn't poll the general public as @Ryan suggests; nor the mathematicians, which I suggest; but rather the metaphysicians! Well that c...
No it's not. When you get in your car and start driving to the store, do you experience infinite acceleration? What's that feel like, exactly? Accordi...
You ask a good question, and one I can't answer. This is the only thing you've ever said to me that has made me stop and think, and for which I have n...
This I would disagree with. One can take the viewpoint that symbolic math is a human endeavor; and that a thing has mathematical existence whenever a ...
