1. ### Calculate the mass defect of a molecule without empirical mass

Hello, I'm currently writing a chemistry program. The user can create any kind of atom he can imagine, and then combine them into molecules. To properly calculate all the energies involved I need a formula to calculate the mass defect of a nucleus. I mustn't use empirical data to allow for...
2. ### Simplified theories for gravity?

I didn't think of the measurement issue, it's a good proof against. I don't quite get the context in which objects would scale differently, but I guess I can google that. Anyways, thank you for taking the time to help me!
3. ### Simplified theories for gravity?

weird, we covered general relativity (tangentially only though) and our prof made sure to tell use that there were a couple of working theories regarding gravity. And I've read similar things in other threads here. But most of them seem overly complex so I was hoping that perhaps there were a...
4. ### Simplified theories for gravity?

Hey, I was wondering, are there any major theories about gravity that actually try to simplify it all? Like, I recently heard that potentially the universe is expanding exponentially. It got me thinking. Couldn't this be translated to what gravity is? I mean, we know that gravity depends on the...
5. ### Calculate throw angle to have the curve cross a certain point

wow, I wouldn't have thought I'd find other game makers here :D I think I now see that time is an essential part and I think I've managed to create some very close approximations based on delta y and delta x compared to the x speed and max x speed. I can't finish it until I have the jump tangent...
6. ### Calculate throw angle to have the curve cross a certain point

Hello, I'm not sure if this is the right section because this is somewhat of a hybrid of math and physics. Say I have a ball in 3D space, its initial position and its' initial acceleration. Furthermore I have another point in 3D space which I want the ball to pass through, if possible. The...
