I was asking some Big Bang related question on Reddit and someone replied "The big bang is an explosion of space itself. A shock wave requires an explosion propagating into pre-existing material. Not only was there no pre-existing material, there was no pre-existing space to hold it. This all...

F=ma, in the two cases the mass is different, the force is the same, so you would get a different acceleration.

I think you'll have to post the original question to get a clear reply. All that comes to mind is that gravity had already, in some way, been accounted for.

Yes its right! You'll have to look up mulling paint I guess to get good info. But anyhow basically all you need to know is that powders have to be really finely ground into the carrying medium to disperse it evenly eg by hand with paint this equates to a flat stone, oil, pigment and another flat...

I think there was some experiment that managed to detect some perturbation at either slit as the electron passed and showed it does indeed only go through one slit.

It depends on what kind of silicon polymer you have. Usually they are gels or thick fluids which will hold onto suspensions. If it is a fluid it is a complicated but not too difficult subject. It depends on such things as the polarities of what you are adding and whether they are attracted to...

I would approach it as 3 concentric circles, calculate the energy of each disc and add them together. https://www.physicsforums.com/threads/rotational-kinetic-energy-of-a-solid-disk.181191/

Liquids are mixed with liquids, powders are often ground in, a process called mulling.

The gun isn't like a rifle it's more like a shot gun spraying the electrons out. As long as they get through the screen they will register. Particles this small are associated with having some wave form like properties. If you think of a small toy boat heading towards a slit with its own bow...

Sorry I know the variables a, b, c, and d but I don't know x, y. It looks as though I might be able to do something with modular arithmetic given that both x(ax+b) and y(cy+d) now seem to both be integer multiples in other words either x or ax+b must necessarily contain some factors in common...

6 - it's been a long time since I read his excellent autobiography.

Homework Statement I am a hobbyist looking for solutions to ax^2 + bx - cy^2 - dy = 0 where all variables are integers and are non-zero. Is there a method of doing this effectively? Homework EquationsThe Attempt at a Solution I can look at the numbers produced by ax^2 + bx vs cy^2 + dy and see...

Yes I am painting the frames of wooden windows with exterior paint. The binders in the modern formulations are not lasting that long, and it's very time consuming to paint them every 3 years or so, hence the reason for my looking to improve the longevity of the paint. I know Borek, you didn't...

Hi I am looking to repaint my windows. I've noticed that black paint lasts very well generally. I don't really want my windows black. Is there anyway I can reduce uv damage to the binder in the paint by adding some UV blocking colour? I've googled UV blocking pigments but it doesn't seem to come...

A good point above. Even appoint a neutral intermediary?
