Awesome you commented on my vid! Photonic propulsion is on my list of things to try. My last boss from the lab I worked in offered to let me use his 125W laser to try this. But if I were to shoot a piece of foil with this ruby laser, I could impart about 5x10^-7 kg*m/s of momentum with a single reflection. This is small, but significant on a very lightweight piece of foil. I don't have a vacuum setup for this though. But, my other idea is cooler... If I took the output coupler (partially reflective mirror) off the laser, and used a freely moving piece of foil instead as a mirror, then the light would bounce back and forth many times imparting lots of momentum to the foil, giving many thousands of reflections. This has two issues though, one if the mirror got slightly misaligned, the energy would dissipate nearly immediately and would stop propelling the foil. This could be partially prevented with foil that has a precise concave curvature on it. The other issue is that now there would be no way for the light to escape, so the electric field between the mirrors would get HUGE, and might vaporize the foil and/or the other mirror. But if somehow I could get this to work perfectly for a millisecond, it would accelerate a 5mg piece of foil to 150 km *per second*. At that point though I'd need a flat mirror though, and there's no way I'd keep it aligned, (plus other issues like pulse risetime and cavity and doppler losses) but man that would be so cool to do in space. But even a microsecond of this in a vacuum chamber would send the foil smashing into the wall of the chamber...so the theory is definitely testable.

Id like to request that you use a large vacuum chamber while shooting the gold foil. Thank you.

Cody'sLab hi Cody's La

Humm do you think you could set one of the mirrors on a precision balance?

Interesting, I believe one of the methods of genetically modifying living things is accelerating gold particles coated with the new genetic material and is fired scatter shot at plants. However if I recall the success rate of the new genetic material being integrated into the living thing is low. Another method uses a carrier organism which is more effective. I believe I read this info in an article on glowing trees.

Electronoob: Geeking Out It didn't even hurt like I expected it would everything went black in my right eye and when I started getting sight back everything was dark purple for over an hour. It was one of the craziest things I've ever seen with my eyes. In the short flash I watched green turn dark blue then fade to black.

I'm so sorry to hear this. :( Have you been to a doctor? There are things they can do to minimize damage soon after a laser eye injury. And although you'll likely never have a full recovery, most people with laser eye injuries do see some healing over time.

styropyro Yes I did and I have to go to a retinal specialist but they said it's bad luck and pretty bad and that I'm lucky it wasn't worse. I still have peripheral vision which seems more important to me since I still have a good eye.

Oof

Holy Fuck this is why I don't fuck around with high powered lasers. Even with proper protection I am kinda scared. I am sorry to hear about the incident :(

Yo they nerfed cav dude

Moamen Farid the nerf did nothing but buff her range, if u were to shoot ppl before and they turned and killed u, they would be put low and just bc u had no skill but a good gun, now the gun has better range, and noobs no longer get rewarded by getting good players low without any skill being involved

Thank you for existing...see what we can all do if we set ourselves to understanding and learning...nerds like us can do anything...

How can a greater number of photons in the same space create pressure. Aren't photons single spin particles which means that no matter how many there are in a single space more can fit... at least till there are so many photons that a blackhole is created and swallows up anything within its radius

@@paxtonpiasecki7439 photons don't have degeneracy pressure because they are bosons, but that doesn't mean they can't generate any pressure. Whenever they hit an electron, they exchange momentum with it, which over a macroscopic area and timeframe is seen as a pressure. The effect is called radiation pressure if you want to look it up Edit: In fact, gas pressure works on a very similar mechanism, with the degeneracy component being negligible

It's also perfectly legal under federal law to build conventional guns as long as you don't sell them.

America is really good at not regulating things. Usually it leads to awesome stuff like this. Unfortunately, our general compulsion to reject government oversight mean it isn't there when it's needed. We're perfectly allowed to build improvised weaponry in our basements, but medical companies are allowed to (and this isn't an exaggeration) put the next two generations of our families into debt if we happen to get injured.

Josh Lewis NICE one! thumbs up.

Or telling an SJW that there’s only 2 genders

holy shit

Ruby lasers are quite inefficient: only 1-2% of the energy winds up in the beam. So this laser is probably only putting around 100-200J on the target.

But you also have to take into account the time it takes to transfer the kinetic energy of a bullet when compared to A FREAKING BEAM OF LIGHT. I'm guessing most materials can't handle accumulating/transferring/dissipating even that amount of energy at near light speeds.

well you can see that in the video: where a 100-200J bullet would ram the plastic in its path out of the way and ultimately embed itself in the block, the laser vaporizes the surface of the block, and the resulting cloud of super heated gas literally explodes! Far faster and more violent than a bullet. The thing is that vaporizing a material takes a lot more power than simply shoving it out of the way, so the laser pulse cannot drill as far into the block as a bullet of the same energy would (even without the ablative shielding effect discussed in the video). On the other hand, if you scale the laser up enough the explosion itself would remove more material than the laser pulse by cracking/shattering the material around the initial laser hit.

Alaric _ this laser works in the visible spectrum, so the air shouldn't absorb it much over the distances involved.
