Participants explore the implications of changing variables (radius and height) and the appropriate differentiation techniques to apply. One participant presents the volume formula for a cone, V = (1/3) (pi) (r^2) (h), and seeks guidance on how to ...Fri, 10 Apr 2026 19:48:00 GMThttps://www.physicsforums.com/threads/this-one-moved-me.1084780/See: Thanks Bill I think, at rock bottom, math is motivated by an abstraction of physical reality. Why that abstraction was chosen, and even why to some people it has appeal, and others go 'yuck', is a matter for psychological research. You see this in things like the small minority of people that firmly support LET, and those like me who prefer an abstract presentation based on symmetries ...Sun, 12 Apr 2026 16:11:00 GMThttps://www.physicsforums.com/threads/does-a-moving-particle-count-as-a-wave.1084781/According to the definition of a wave from Wikipedia: A wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities. Now, imagine a particle as a disturbance in mass density that propagates through space and time. From this perspective, I cannot think of a...Mon, 13 Apr 2026 01:22:00 GMThttps://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/In Dirac's Principles of Quantum Mechanics published in 1930 he introduced a "convenient notation" he referred to as a "delta function" which he treated as a continuum analog to the discrete Kronecker delta.Sun, 12 Apr 2026 20:21:00 GMThttps://www.physicsforums.com/threads/how-is-literally-everything-in-physics-not-binary.1084809/The problem with "sharing what you know" is that unless it commonly accepted, you will need citations.

I heard 2 people babbling in a youtube video about "motion theory" and about how it explains physics better. I'm wondering is this just crackpot nonsense from "conspiracy theorists" or an actual topic to learn about? They kept talking about motion of loops but...Tue, 14 Apr 2026 00:31:00 GMThttps://www.physicsforums.com/threads/mcnp-data-card-errors.1078607/I'm trying to resolve two separate fatal errors in my MCNP deck. One is claiming that I'm mixing atom and weight fractions within a single material card, which I'm clearly not if you take a peek at the material definitions.
