‘Our death ray doesn’t seem to be working, I’m standing right in it, and I’m not dead yet.’
A true scientist.

Obviously it's not going to burn wood, I wanted to see it on a roman sail.
It will burn wood
@@thesheepstationcook8266 How?
@@julzyboy8960 Have the ship - wood in the focus of a parabola of mirrors - basic geometry.

@@julzyboy8960 have you never played with a looking glass in a sunny day as a child? It can totally burn wood
@@Suavek69 It's called a magnifying glass not a "looking glass".
I just saw these videos for the first time and the military historian in me flared up. The experiments failed as the intended target was never recreated. The ancient ships, especially Roman’, used a variety of low flash point minerals oils or tar to rustproof their ships, 200 F perhaps? Then there were the onboard flammable items such as Greek fire. Firefighting was an essential task within those ships for a reason. Either or, the target material should be recreated first. Another thing is I wonder if they did not dump flammable items in the water and the rays merely blinded the ships, and other accelerants triggered the fire. But, from a military historical perspective, remote flash ignition was a widely used method even back then.
Archimedes wasn't just smart, he was genius. I believe that he did it, but we can't find how. Perhaps, we don't try hard enough. I think that he used many mirrors that were massive and lit up the sails, not the hull. Also the beam was focused.
flat mirrors didn't help the boys either. I vote for try harder.
Or highly polished bronze, giving it almost a mirror finish
This.
I mean they theoretically proved it works with more mirrors and showed that their array was flawed so by that logic add more mirrors and it will work significantly better
Yes but practically it won't work.
@@massatube the opposite. Enough mirrors on a single area would ignite it. It is practical, if you have thousands of soldiers taking part.
@@imarchello To set an ant on fire you need a magnifiying glass 1000x bigger. To set a ship the size of to houses on fire you whould need a magnifiying glass 1000x bigger. my man archemedis got shares in big glass
Ships weren't that big back then. A viking longboat was bigger than a Greek ship @@gamebox131
you will never burn something with only mirrors alone unless they have low ignite point. To burn wood ships ,you need something else , like some convex lens. If you use the mirror to focus all that light into a convex lens or something like a convex lens ( Archimedes experimented a lot with water), you will be able to obtain your " death ray" . Off course we don't know what mirror archimedes used because i am pretty sure he did not use modern mirrors used in this experiment ( ancient mirrors were made from polished metal/ bronze and were not flat like this mirrors)
Modern solar ovens boil water to super steam levels they can burn wood but they are massive and in the dessert
There's so much wrong with this one
There’s a lot not taken in consideration
Well,the wood might not be on fire with 200 degrees, but anyone considered that they might have aimed for the crew instead? Not sure if the romans brought enough sunscreen and sunglasses for this occasion, so probably a bunch of blind soldiers in agony are not that much of a threat anymore. Besides it seems the city of London has proved this works well with cars.
Simple - 70 shields in a Parabola when the ship is in the Focus - all you need to find the vertex, the focus, the latus rectum, the directrix and the axis of symmetry - and light her up
Interesting is there a possible way to put that in a easier way to understand for me if you don't mind
@@uncuttcoffeeofficial Basic Geometry. Every Mirror has a focal point - before that point and after that point there is no power as the photon lose strength - so find the focal point for a mirror or an array of 70 mirrors - 1 at the vertex and 34 on either side as a parabola - then maximum photon rays are focused on the target ship - simple - if you do it wrong it lacks the power to ignite.
@@thesheepstationcook8266 you sound like the type of guy I want on my team
@@uncuttcoffeeofficial Once you understand that a mirror has a focal point and that is where it is strongest - that is the point where it is powerful - but remember that a circle is a series of points equidistant from the centre point. A Parabola is a series of points that are equidistant from the directrix at 90 degrees and the focus - this is where ordinary sunlight becomes a weapon. The same as a magnifying glass - if not in the focus it will not start a fire - in focus - look out.
@@thesheepstationcook8266 has this ever been completed successfully in modern times that you know of? Interesting topic
i don't think those was archimedes' design
DEFINITLY
Did I just see a grown man pour gasoline onto a fire?
It could be that the Romans just had it hit their eyes which might've blinded them enough for the boat to catch fire by other means without them seeing it. Or the heat was focused on their sails or something else that was flammable.
Well maybe they had lenses who knows. With a lens you can even melt rocks.
if you were trying to figure out how he did it rather than trying to prove whether it would work or not. maybe you could do it.
you can do it
What if you had several big these mirror constructiosn, either all aiming at one target, or them all aiming at a central one which directs all that light to a singular spot.
I'm guessing they probably used a lot of mirrors maybe parabolic design along all the walls pointed at the romans, the result might not be lighting them on fire but maybe burning sails or burning the wax or simply not allowing them to even look at the walls being an easy target for catapults or arrows. Rest must be myth.
On a sail, and many rigs on the 7mile wall along the coast of the city
Molotov cocktails are considered destructive devices. I’m curious if there was any legal issues with this one
Well who's going to arrest them.
1. Could have lit the sail.
2. That focal length looks far too close to be at the focal point for that lens.
hmm... i thought you had to align the mirrors so that they direct the light onto a magnifying glass and the magnifying glass should create the focal point and not all the mirrors directed onto the ship.
I don’t think archimedes was looking to create a death ray, rather an optical dazzle. By shining lights on the ships the helm mens were blinded and so were the crew. The ships could have ran a ground or ran into each other. You can’t operate. Some of the crew were temporary or were blinded.
Why not???
@@georgex231 Applying the scientific method and testing. He probably knew it did not work. Archimedes was Archimedes after all.
His understanding of geometry was a foundation Euclid built on. He probably understood the principle of distance squared and diffusion.
Did you ever tried to focus 400 bronze plates controlled by different humans on 1 moving ship far far away? No human being, aside from your PC generation, was thinking to target the light on the SHIP. That would have totally dissolved the light power of each source. Back in the day many families had a bronze plate at home to eat from. And there was a fun game among the folks, involving shining them into other people eyes. We knew the romans would attack us by the sea. So my suggestion was simply for everyone owning a plate to go out and target it on to the NEXT plate and so on until multiple rows will target the MAIN specially made mirror with focus changer. No need to construct bulky big reflectors, no one would even able to hold. The square came from the length of the chain and the number of chains and focusing was simple because you had to focus only 1 mirror. Yes some had to hold the plates with wooden forks, as they got quite hot. We did not target the ship in fact, we target the vessel crew. That way people will stop vesseling on one side, making the ship uncontrollable. Sadly romans kept a big distance between the ships, so they barely collide. Burning a hole at the waterline took like 1 minute. But before that the main deck will catch a fire. With 50 or so ships it was fun. Until we burned the holder of the main mirror we managed to sink 14 of the ships (1 with a catapult) at approx. 500m distance. In the mean time several ships managed to reach the shore already. While other captains were afraid to come near. Despite that many romans that we sank reached land by swimming, but without heavy metal gear on.
In fact you humans even are not familiar with own technology. Look at the space telescopes put into the array around the main listening device, reflecting the signal into it, to make distant space signals more clear. Same principle, but the other way around.
We forgot about using celestial bronze- oh wait, this is mythbusters not Percy Jackson ;-;
why didn't you try with a magnifying glass lol love you trick people
Your reflector is so small.
So badly done
