wait, so you saym, that given a strong enough laser, steve could levitate the closest thing to a laser minecraft has is a beacon, which we can assume is a kind of crystal based laser, using the nether star as the medium so, we need to know how powerful a beacon is well, since it is rather harmless, i can assume it's a really weak laser, maybe 5 mW we will need the total power 50 beacons to levitate a grain of diamond powder a full set of diamond armor weight 526.5 kg (source: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8KuH0-994Hk.html) i don't have time to do the excat math, but i'll assume you'll need the death star (cleverly hidden in styropyro's basement, so the empire won't find out) to levitate just the diamond armor, not including steve
Thanks! If you find the equations for the beam intensity across the beam, and also for how that changes with distance from the focus, you can convert the intensities to energy density (also has units of pressure, Pascal or Joules/meter^3) by dividing the Intensity at a point by the speed of light (Watts/meter^2)/(Meters/second) = (Joules/meter^3). These stationary (nearly time invariant) pressure gradients are easier to work with than momentum equations. Also, you might want to look at conical lenses that produce Bessel function pressure (energy density) cavities that can be much larger and farther away from the source. The electric and magnetic fields can be found from the energy density from B^2/(2 mu0) = pressure Pascals = e0*E^2/2, where B is in Tesla, E is in Volts per meter, mu0 if the Codata or NIST "vacuum magnetic permeability and e0 is the vacuum electric permittivity. Stupid names. But that is what they call them today. I keep asking groups to look for the gravitational effects. The earths gravitational energy density is calculated from g^2/(8 pi G) where g is in meters/second^2 and G is the Codata gravitational constant ("Big G"). The result is also in Joules/meter^3 or Pascal. And you will find the B field equivalent of the gravitational field is about 380 Tesla. The E field is just B times the speed of light or about 115 GigaVolts/meter. The average energy density of fluctuations at the earths surface is about 1260 Electron Volts. so you might be able to use your YAG laser and "High Harmonic Generation" to run a beam continuously at the energy densities close to the gravitational range. It is a spectrum, not a single constant value. I think it matches the solar neutrino spectrum fairly closely, with a roughly blackbody spectrum from below 1 eV per photon to a few tens of MeV with a peak about 1.26 KeV. In spite of your love for high total POWER, you might tweak your personal wants to include "INTENSITY!" If you want to make "Mr Fusion" (are you old enough to have seen Back to the Future II and III? You do not need massive size, only precise focus and high INTENSITY!! (1 ExaWatt/meter^2 = 1 Watt/nanoMeter^2) If you run for several days, the changes in the intensity should show SOME correlation with the magnetic variations , with seismic accelerations, and with the vector tidal Newtonian acceleration at the instrument from the sun on the device, minus the sun on center of the earth. Plus the moon acceleration on the instrument minus the moon on the center of the earth, plus centrifugal accelerations at the station. If you ever get that far, contact me on ResearchGate.

Ikr? I heard someone built a electron gun out of old tv tubes and shit. It like vaporizes shit instantly. I just hope that fool doesn't attach it to a drone. That fool could take over country's. Disable power plants, governments. Shit is scary af yo.
I'm so happy he keeps posting, I missed his videos and was afraid he was gone for good. RU-vid has been lacking quality content and this channel gives me hope.
Yes! Although he was slightly wrong. No pair production occurs in a vacuum, as it would need a nucleus to satisfy conservation of energy. I would love to see him make matter-antimatter pairs tho. Give it 20 years he'll have his own big ass research facility.
Hey Mate !!! Great video. I actually work with optically levitated nanoparticles (PhD in the group of R. Quidant... he is in the Vamivakas paper you show). If you are curious to know more stuff 'from the inside' of the field, let me know! Don't stop doing nice videos like this one
Man seriously you are my biggest inspiration right now, I'm studying optometry I'm having my optic physics and optic geometry classes this semester and this videos are amazing, you have no idea
10mintwo Actually where I come from physics (plus math of course) IS part of chemistry engineering courses at universities. But yeah, this is university-grade physics for sure.
Even had to go through this studying biology. I guess its required in every natural science. Wouldn't be able to comprehend these formulas anymore without a lot of reiteration and chocolate for the frustration, though. :D
"Do not pipet liquids by mouth" Damn, I always alloquated my ammonium sulfate precipitates by mouth back when I was an intern. Guess that's why they let me go.
It's one of those channels which actually demonstrates quite interesting phenomena with great precision, detail and burning stuff.... I like it very much.
I'm really impressed with your intelligence you're definitely going to go places! You teach a 45 year old man new stuff in every video! thank you, I appreciate you! EDIT: Damn kid, you make me feel stupid
only difference between a clever person and a stupid one is the stupid one never lets themselves be told they're stupid. (you'd catch the bright one telling themselves off for being stupid usually) (that and dont worry vector calculus gives everyone a headache)
Amazing. I was impressed by your mathematical skill. You are not just someone who messes around with lasers without knowing exactly what you are doing. Incredible work. “Some of my more observant viewers are going to...” I imagine if anyone watching this channel really has the knowledge to pin point that
I have recently found your videos and I have to say even though some things are above more skill set and knowledge you do a good job explaining things and making this comedic and educational. Thank you
I like how the tone of his voice is like “I know all this cool science stuff and I’m going to make you feel stupid by showing it to you anyways. You’re welcome.”
@@theshankman8682 if thats true than he dodged a bu--llet working for that shlock of a channel. edited the B word for youtube algos not to raise eyebrow.
The counteracting force acts on the photons, bending them away. Since there is a downward attractive force on Earth, the majority of the photons will be bent upwards, meaning that the diamond speck will appear shinier from above than from below.
1:07 first person I've ever seen who snuffs matches by banging their hand on a table instead of, you know, blowing it out or dipping it in water anyway, your still a genius with electronics and lasers. Change the world!
Would it be possible to use this physical "tool" to change how metal 3D printing is done? Instead of adding layers of metal and fuse them with laser, would it be possible to continuously channel metal particles through a "laser straw" straight to the wanted position and melt it in place with another laser beam? Like a 3D sewing machine?
Fun Idea: Using this method, make a quantum dot sorting machine. Pick them up off the table and move them left or right proportional to the average fluorescence difference frequency to a reference sample. Even if you pick up multiple randomly chosen dots at a time, the method will order them eventually.
I dont understand english very fluently plus this physics concepts makes me to not understand almost anything but this guy has some area that keeps me to watch the video until the end. Bravo.
Your channel name should be laser lover. I like your videos. Before watching your videos, I thought that people dont like these kind of activities but your count of subscribers proved me wrong. Thank you for making such videos.
stuff like the shwinger limit just make me think people will do anything in pursuit of academic payout. absolute conjecture and hocus pocus. other than that awesome video my man haha, well done and great job showing all the work/formulas.
@6:25 Although I don't know most of the math you're using, I feel like you're still missing an important fact: The car doesn't have the same index of refraction as the diamond.
I'm not very educated in this field of science. But I do find it very interesting. If you wouldn't mind breaking down some of this into laymen terms. For example the levitating laser. A reference of how much power it would take to run a laser of that magnitude. The fact that you said it would vaporize the car really helped me understand its magnitude
@@styropyro *That's not the biggest concern. The Main concern (if you're gonna propel a Spaceship to another Star) would be, Tesla Spaceman ZOOMING by while Texting and Friggin' everything up.....like he does.*
@@jnevercast No if anything a diamond should be easier to 'fry',there are many total internal reflections in a diamond,but since it has a really high melting point it doesn't.
I just started watching your videos on LASERs and really get a kick and a laugh out of them. Thanks. I've been involved with LASERs for decades and it's good to see someone who has a great joy in them. I can't wait to see what you do in the future, and I don't mean on RU-vid... P.S. It's way more fun watching you explain LASER tweezers than the 96 year old Physicist Arthur Ashkin grumble his way through his presentation. (He is still pretty awesome but too much like me.)
Don't let anyone tell you your nothing but a genius. I've been following you for some time and you are one of the smartest minds on the planet. If there is anything I can do to help your resarch and playfulness with science just let me know.
Aside from the cool concepts in this video, I love the whiteboard maths, but it raises the question. "Is this the first time you used a laser pointer as it was intended?" That it is such a puny one, was hilarious given the channel content. Thanks for another thought provoking video.
Hey styropyro, great video! I have a question though... Considering that the particles aggregate toward the areas of greatest focal intensity within the laser's beam, wouldn't it be possible to move a suspended particle along the path of the beam by adjusting where the focal point is? If so, you could make a miniature tractor beam... You could make a particle or even those diamonds move back and forth by adjusting the light going through the lenses. While I'm no physicist, I think it would be an awesome concept to see implemented...
I imagine that changing the focus would likely make the particle fall out of the beam. If you could use two or three lasers together though and shift them one after the other that sounds like something that could work. Would be interesting to see if you can get two beams focused on the same point and transfer the diamond from one to the other.
This principle actually works and is used in real labs. You can mount a lens on a translation stage and move the lens and the trapped atoms fairly quickly. This is used to move the atoms from something called a 2D MOT to a 3D MOT, basically two different stages of an experiment.
The biggest problem, really, is that energy densities which would levitate a car would appear to be high enough to melt it into a uniform spherical blob and probably turn much of it into a plasma in the process.
Well, bigger problem would be that if you were to try it in the presence of air (or atmosphere of any gas), the air would electrically broke down under the electric part of the electromagnetic wave into a ball of plasma, but the plasma is absorbing the light afterwards... And you're pumping zettawatts of power into it... BOOM :D
So the laser based tractor beam would also function as a pretty good energy weapon. Nice. (Or possibly blow itself up when it hits the air, not certain)
I really wanna know a few things here. One, what is the small paper in the frame above the laser wavelength chart, second what is the poster with the phoenix on it, and finally what is the small paper/poster with the circular chart in black and white or grey??
the small paper with the red border has thin lens equations for quick optical design. the poster with the phoenix is from the company Esco Optics...they made the incredibly tough mirrors on my ruby laser. the circular chart is the smith chart.
styropyro Sweet dude! I was actually talking about the one above the quick optical thin lens equations. It has a black border or frame and a beige paper inside.
Pragetamiiear To be honest dude, a lot of the heavy math is beyond me. The best way to learn about the principals, equations, and effects is to just look them up! I always (usually) find an elementary explanation somewhere. The simple solution is, Genius+Lasers= Styropyro 😎😎
redstone craft guy solar sail is simpler - just using photonic momentum to propel a reflective surface, rather than manipulate the position of an object in multiple axes. A solar sail is "push only" whereas optical tweezers can move something to any position in 3D space
I'm impressed that it was so easy to lock-in the mass. A++ Styro! Please breakdown the circiut components of your RUBY monster laser. I almost bought a 2"x1/4" laser ready rod long ago for 180, felt it was a gamble.
now that you have a levitated particle.. can you run your light wave center through of a higher energy secondary carrier wave and project the particle across the room?
I doubted the levitation using the sharpie would work, but after using a stronger, violet laser, the particles actually stayed there! I didn’t know, that sharpie-particles are that refractive, though I know that they can cause cancer, so I might go for the diamonds in the future. Thanks, Styro!
Space time is a meaningless concept because time is just a concept, it interacts with matter in no way shape or form. Time is not a traversable or manipulatable medium, it's thoughts in our heads.
This guy is an example of how I hope my children turn out, extremely smart with a bright future ahead of him, someone who will contribute to society. At least in the US, too many parents focus on sports. Its unbelievable the extremes some will go hoping a for a scholarship or for dreams of a pro.
