Hello fellow Astronomers,
My name is Carl, and I wonder about every single one of the stars. All of them are big, wonderful, bodies of gas who spend every second of their day giving off heat and light. The stars are everything wonderful in the Cosmos. Honestly, have any of you ever stood outside and stare into the sky? I mean, it's just such an overwhelming sight, but the galaxies take it to a whole new level. It's an even more amazing sight than the stars themselves.
Don't be afraid. The Cosmos are our future. We just have to stop this fighting before we destroy ourselves. The Cosmos is full of "star-stuff", and we're all made up of it. What part of the Cosmos do you like, other than the galaxies, stars, and "glorious dawns"? The Cosmos is our future home, and living there is going to be a very real heaven. (I was just gazing up at the Cosmos; sky was SO cash). You should all go outside and stare up at the billions and billions of stars. Thanks for listening.

I need to build fairly small (~5cm radius and 15cm length) nose cones, similar to those on commercial airliners for a physics experiment. These cones will be based on volumes of revolution of certain graphs (x, x^1/5, x^1/4, etc.)
My problem is constructing these. I considered building a frame out of a lightweight malleable material, and then filling this with paper and wrapping the structure in aluminium foil. Any other ideas, however, would be greatly appreciated.
It'd also be really helpful if anyone could propose a material with which I could build the frame (I was thinking of using the metal part of a spiral bound notepad).
Thanks in advance.

Hey, I've been trying to teach myself math for the last couple of weeks, dashed through single and multivariate calculus and now I'm doing some eigenvalue problems. I'm okay with problems that are like, "show that this is an eigenfunction of (operator)" but I just opened a new book, and it wants me to find the eigenfunctions. I can understand intuitively that the answer is e^ax, because the integral and derivative of the function are equal to the function times a constant, but I want to know how less intuitive problems would be derived.
