You might not know that each color-lit arch is actually a brilliant demonstration of physics in action. Let's dive into the science behind rainbows - yes, including how are rainbows formed - and uncover the lore that surrounds these colorful arcs. Gary Yeowell / Getty Images When you hear...
Some scientists speculate magnetite becomes magnetic when struck by lightning. Others theorize that pieces of magnetite became magnets when Earth was first formed. The domains aligned with Earth's magnetic field while iron oxide was molten and flexible. The most common method of making magnets today...
Here we report observations of a relatively unknown type of discharge, called fast positive breakdown, that is the cause of high-power discharges known as narrow bipolar events. The breakdown is found to have a wide range of strengths and is the initiating event of numerous lightning discharges...
forbidding slopes that offer at least 45-degree descents. The run is often a "make it up as you go" course of previously untouched powder. Skiers must make lightning-fast decisions throughout the run, lest they careen into a tree, a rock or off the side of the mountain ...
2. What is the oldest known material formed on Earth? Calcite Copper Quartz Zircon crystal Discovered in 2001 in the Jack Hills of Western Australia, zircon crystal is the oldest known material formed on Earth. Learn More: 12 Of The Oldest Objects Ever Discovered 3. Which newspaper called the...
But while faster-than-light travel isn't guaranteed impossible, we'd need to harness some pretty exotic physics to make it work. Luckily for sci-fi enthusiasts and theoretical physicists alike, there are lots of avenues to explore. All we have to do is figure out how to not move ourselves...
Astronomers can hunt for signatures of elements in planets and their atmospheres and determine the ratio of rocky matter to icy gaseous matter present when the planet was born. Thatshouldtell them how far away from the star the planet formed. ...
Explain why it is more dangerous to be on the top of a hill or mountain during a lightning storm than on level ground. What produces the wet underside of a glacier, which enables it to slip down elevated regions? Which type of plate boundary is most closely associated with the formation ...
the physics of large-scale wildfires remain so poorly understood that fire-modeling software is often effectively powerless to predict where they will next occur, much less how they will unfold once they do. if there is any good news, it is that, as saah puts it, “the science for a ...
Naturally, any breakdown in your body's electrical system is a real problem. When you get an electric shock, it interrupts the normal operation of the system, sort of like a power surge. A shock at the lightning level can cause your body to stop. The electrical process doesn't work anym...
