\"The<\/p>\n

Since mathematicians became a thing in Babylonia somewhere around 2000 BC, number crunchers have been mystified by ocean waves. About 300 years ago, the Leonhard Euler fluid-dynamics equations attempted to describe how fluids move \u2014 and did a decent job of it, too \u2014 but when it comes to the ocean, there are so many variables that prediction becomes nearly impossible. But new research into something almost impossibly complicated could be a very large step in the wave prediction world.<\/p>\n

Before we get into it, it will help to know a few things. Mathematicians are able to solve what are called Euler\u2019s equations and predict how fluid will move over a given time period if they know the location and velocity of each individual drop of water. The equations are similar to how Jeopardy works: the waves, eddies, tsunamis, currents, and tides are all answers to them. Using the equations, researchers are able to take the location from the space the water occupies and the velocity from its speed then extrapolate forward in time to find the answer to what those water droplets will eventually do. In theory, anyway. In reality, of course, there is just too much data to accurately say what will happen to the water droplets down the road because the smallest of changes anywhere along that road can drastically change the outcome.<\/p>\n

Even when researchers dumb down Euler\u2019s equations to their simplest form \u2014 a steady train of rolling waves with no friction \u2014 they found that getting to an answer with any degree of scientific certainty was impossible. Tiny deviations, like a gust of wind or errant drop of water, will disrupt the flow. But researchers looking closer at the moments of instability found something odd.<\/p>\n

\u201cThere are zones where waves are stable, then unstable, then stable again, like a chain of islands,\u201d wrote Joseph Howlett for Wired<\/a>. \u201cThe new research finally proved that these alternating islands\u2019 of stability and instability really exist \u2014 and they go on infinitely.\u201d<\/p>\n

Wave prediction is still a confounding problem, despite these new advances \u2014 even for researchers actively working on it. Like a group of Italian mathematicians led by Alberto Maspero out of Roma Tre University in Rome. They think they\u2019ve finally figured out away to use mathematics to predict exactly when instabilities in waves occur, and when they are stable.\u00a0<\/a><\/p>\n

The process involves a whole lot of complicated solutions difficult for the layperson to understand \u2013 and even researchers for that matter.<\/p>\n

\u201cBefore starting math, I thought water waves were something very understood \u2014 not a problem at all,\u201d said Paolo Ventura<\/a>, a postdoctoral fellow at the Swiss Federal Institute of Technology Lausanne and Maspero\u2019s former graduate student. \u201cBut in reality, they are just strange.\u201d<\/p>\n

So what does that mean? Well, unless you\u2019re an Italian mathematician working on the problem, probably not much\u2026 yet. But it gives researchers invaluable information into a whole gamut of fluid-motion problems and in the future, we might be able to better predict how destructive a tsunami will be or when a rogue wave<\/a> might appear.<\/p>\n","protected":false},"excerpt":{"rendered":"Questions?
