You are confusing the 3rd Law with the 2nd Law. Two forces acting on the same piece of string are not a 3rd Law pair. 3rd Law pair... -
weirdoguy reacted to SergejMaterov's post in the thread I Would gravitons theoretically act like photons? with
Skeptical.
You can of course be skeptical about my previous post, but: If it does exist, then formally the "graviton" should be very similar to the... -
I don't know many many times and how many different ways it needs to be explained.

weirdoguy reacted to SergejMaterov's post in the thread I Would gravitons theoretically act like photons? with Skeptical.
I think it is too early to talk about "graviton" at all for obvious reasons: 1. quantum gravity has not been built 2. "graviton" has not...

weirdoguy reacted to Catastrophe's post in the thread B Flatlander analogy of spherical surface as observable universe with Skeptical.
Not to worry. I am happy with my position on this. Thanks for your comments. Cat :) :) :)

weirdoguy replied to the thread I Problem in understanding instantaneous velocity.No, the limit of those lines is the tangent line. You are confusing limit with the sequence and whether or not it's part of the...

weirdoguy reacted to Gavran's post in the thread I Problem in understanding instantaneous velocity with Skeptical.
No, it does not. The limit means that the secant line approaches the tangent line, but it never becomes the tangent line.

Like.
No. Limit doesn't mean the process of approaching to the tangent line itself. Limit is just a number (coefficient of tangent line slope). -
weirdoguy replied to the thread B A question about warp bubbles and navigation.And it is perfectly clear from the context and how the thread went on.

weirdoguy reacted to DaveC426913's post in the thread B A question about warp bubbles and navigation with
Sad.
My concern stems from the opening line, which is: "I've been thinking about the concept of warp drive. From what I understand, when a... -
weirdoguy reacted to Dale's post in the thread B A question about warp bubbles and navigation with Like.
Sometimes people don't understand how impactful that can be. I think it is clear from the context that you want to talk about the...

I was not teaching a course in geometry, but engineering physics. Including a diagram that tries to misrepresent the discription seems...

weirdoguy reacted to Luis's post in the thread B A question about warp bubbles and navigation with Like.
I never said otherwise. I simply said that, in my native language, both the Alcubierre engine and the science-fictional warp drive from...

weirdoguy replied to the thread Geometry: Similar Shapes.@DaveC426913 are you a teacher doing that in your practice? You know, some techniques look perfect on paper, but practically they suck...

So, in this diagram, if AD and BC are not parallel, you would consider this "tricking" people, yes?
