12-year-old solves 2,000-year-old mystery of ancient Greek weapon 'Death

A 12-year-old boy appears to have solved the mystery of the beam weapons depicted in images from several centuries ago, creating the so-called "death ray" once described by Archimedes.

The second-century author Lucian writes that the Greek philosopher created the death ray design to keep Roman warships at bay during the siege of Syracuse in 213-212 BCE.

Archimedes is believed to have used a series of mirrors to focus sunlight on approaching enemy ships, setting them on fire.

But for this there is no clear evidence and researchers have been arguing for years since then.

Many researchers, including the French philosopher René Descartes, considered it fiction.

But Canadian student Brenden Sener has created a simulated death ray using arched mirrors and LED bulbs, proving it can work.

Brenden created a miniature version of the beam and found that by focusing the 50-watt heat source onto a cardboard, the temperature increased as the mirrors were added.

His discovery is similar to that of researchers at the Massachusetts Institute of Technology in the US, who created a replica of Archimedes' gun and found that the death ray could set a wooden ship on fire in 11 minutes.

According to them, a heat source with several mirrors focused on the target at a precise angle can ignite it," says the Canadian Science Fair Journal article.

Brenden has received several physics and engineering awards from Matthews Hall School, from the Thames Valley Science Fair in London.
