In my head, I'm using (delta)(gravitational potential energy) as an analogy to the (delta)(electrical potential energy). So, with a DC circuit with loads connected in series, we can observe a voltage drop across each load. Now, because the current remains the same throughout, it must mean that...

I'm sorry, but I feeling attempting to include money and marketability in something that is about advancing human knowledge severely impurifies such a beautiful piece of academia. That stuff should be for the person himself/herself to understand.

I am by no means familiar with anything in quantum physics, so bear with me. This recent experiment that proved that future events can affect the past for an atom got me thinking, does that mean that, the timeline of atoms is the opposite of ours, and that the end of time for them is what we...

Ow wow! I think I got it! The optimal design for the projectile will be something like a bullet! Maximum use of force from the air expansion by the flat surface on one side, minimum friction by making an incredibly thin edge, and minimum air resistance by the other surface by making it pointed...

Ow, and also, there are a lot of ideal set ups assumed here in this situation, so if you can also highlight what those are, that'd be great too.

Ow God. I forgot to take into account friction... The sphere will have less friction that the cylinder (unless the cylinder was just one point thick), so really, the net force in the direction of the muzzle would be something like (varying force of air pressure) - (friction + air resistance). So...

I'm building a pneumatic spud gun, and am thinking about the volume of the muzzle/barrel. It will be cylindrical (a pvc pipe). The projectile will either be a spherical or cylindrical object (same mass). The muzzle will be connected to the air chamber via a sprinkler valve. So, the aim in this...

I'm a reader of knowledge and a builder and that's all you might want to know about me :).
