The ancients often got it wrong about science — but they weren’t that far off.
There’s a new arsonist in town — one with wings instead of hands.
Know how it acts and stay safe.
These trees shellfishly used the First Nations’ trash to grow.
Take a candle, light it, turn it on its side — we all know what will happen. The convection cell that forms around the flame keeps licking up towards the sky (or ceiling) regardless of the orientation of the fuel. But can the movement of air be overcome, can we make a fire burn horizontally? Well, the short answer is yes, yes we can — we just have to use science.
What do fires and deep sounds have in common? Not much right now, but they might have a lot in the future.Two George Mason University students have designed a device that uses sound waves to put out fires, thus potentially eliminating the need for carrying around huge quantities of water and costly cleaning operations. Here’s how it works:
In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process. Inside a spacecraft or in the International Space Station, however, things are a bit different. Inside you have the same air mixture as on Earth, but because gravity is millions of times smaller an open flame behaves significantly different.
I have nothing but the deepest admiration and respect for fighters – always faithful in the face of peril and always ready to put their necks on the line in order to save people from the hellish depths. As one can imagine, firefighting tech has evolved a great deal from simple fireproof clothing and a bare axe, still there is
Space offers incredibly fascinating experimental conditions for various scientific studies, otherwise very hard or practically impossible to replicate on Earth. Microgravity is something of great interest to scientists, and even simple experiments with fire are extremely insightful. Combustion in space occurs at much lower temperatures and with a lower amount of required oxygen, and to better understand the process, scientists
