A 13-year-old Canadian boy managed to build a working version of Archimedes’ death ray.
And the revelation has left scientists absolutely stunned.
The creation proves that a lauded mythical weapon might actually have been possible.
And this 13-year-old might just have been the one to prove it.

Archimedes’ most fabled weapon – the death ray
Brenden Sener is the Canadian boy at the heart of this incredible story.
The 13-year-old, from Ontario, has a very unique inspiration.
It isn’t Stephen Hawking or anyone from NASA.
His inspiration is the ancient Greek mathematician Archimedes.
Often referred to as the father of mathematics, Archimedes is one of the most famous figures from ancient Greek history.
Many of his ancient ideas and principles are still in use today.
But one of his most legendary devices has been speculated about for hundreds of years.
Scientists have debated whether its existence was even possible.
And that device was the fabled ancient death ray.

Archimedes reportedly developed the death ray to defend Sicily during the Siege of Syracuse.
The siege, which occurred from 2132BC to 212 BC, saw the mathematician defend the European island from the Romans.
According to ancient legend, Archimedes used mirrors to direct the sun towards the sieging ships.
This turned the mirrors into a heat-channelling death ray.
For hundreds of years, its existence has been debated and discussed.

Has a 13-year-old proven it could have existed?
But it might just be a 13-year-old Canadian boy who has proven its existence.
Brenden Sener has been fascinated by Archimedes since he learned about the inventor during a family vacation to Greece.
Speaking to CNN, Sener discussed his fascination with the ancient figure.

“Archimedes was so ahead of his time with his inventions. And it really did revolutionize technology at that time, because Archimedes was thinking about stuff that no one actually had before,” Sener said.
“(The death ray) is such a neat idea that no one at that time would have thought of.”
And Sener has already won awards for his incredible creation, including two gold medals and a Public Library award for his minuscule version of Archimedes’ weapon.

During Sener’s attempt at the ray, he set up a heating lamp facing four small concave mirrors.
Each of these mirrors was tilted to direct light at a piece of cardboard with an ‘X’ mark.
The Canadian boy hypothesized that heat would increase with the number of mirrors added to the target.
Each additional mirror increased the temperature notably, he found. Which means Archimedes was probably right.
What an incredible story of scientific innovation.
