    B Is the Longer Path Quicker in Physics?

    I think I already see my logical mistake. I think only the velocity has to be equal at the end. And I found this: https://en.m.wikipedia.org/wiki/Brachistochrone_curve

    B Is the Longer Path Quicker in Physics?

    It's just a link, Unreal? [Mentor note: The thread title has been edited to be a bit more specific]

    You are correct.

    Algorithm problem involving 3 points and 3 lines in the x,y plane

    By definition in 2 dimensional euclidean geometry, a line that passes between two points will intersect with the line defined by them. You've only given one point for the intersecting line, so ...

    Java How do I prevent threads from interfering with each other in Java?

    Look up apartment threading. I might be out of date, but java has a single UI thread. So updates need to be queued to it.

    Algorithm problem involving 3 points and 3 lines in the x,y plane

    Are you asking to show whether or not (x3,y3) lies on a line between (x1,y1) and (x2,y2)? This is algebra.

    Comp Sci Assigning a variable using a unary operator

    Late to the game, but per the standard post (in/de)crement operators return the altered value. Pre (in/de)crement operators may return the original value, but I don't think they have to return anything (thus undefined behavior in the standard). The optimizer can elect to use the pre increment...

    I just solved a fundamental problem in with SI. Will be submitting paper for peer review. My first hypothesis was pretty solid: But a colleague came up with a better theory I fully support.

    I Given three random numbers between 0 and 1, how to evenly populate a sphere?

    Would not a sphere encompassing a cube with the same center simply have a radius equal to the length of a line from the cube's center to it's corner?

    If ## n>1 ##, show that ## n ## is never a perfect square

    This has been asked here before: Spoiler on link. https://www.physicsforums.com/threads/relationship-between-factorials-and-squares-of-natural-numbers.1011489/#post-6590665 Formally proving it might be non-intuitive, but the starting point is that every factorial will have a factor that is a...

    I have a question about learning Computer Science if someone could help (OSSU)

    I apologize for missing the context. Knuth was mentioned, but I skimmed passed it. He is exceptionally good at fundamentals, but there have been a lot of incremental changes since. We put men on the moon in that era with that technology, and it is still highly relevant today.

    So was: https://en.m.wikipedia.org/wiki/The_Art_of_Computer_Programming A lot has changed, but the fundamentals, not a lot. I wish I could grok quantum computing though. That's the leap right now.

    What has a shape but no volume?

    I was thinking about the same (atmosphere). It is I'll defined. My favorite part is how it drives flat-earthers nuts though.
