If you have ever tried to get something floating in the distance from a lake or ocean, you will know the difficulty. After some toss, you may have gotten it, maybe it was just a waste of effort. According to research conducted by the Australian National University (ANU), they found that as long as you can generate the correct type of water waves, you can control the direction of movement of the floating objects.
The research team used a floating table tennis ball to perform wave experiments in a sink. By precisely manipulating the water wave generator, three-dimensional waves of a fixed size and frequency are generated, and various water waves can achieve various movements of the ball, such as moving forward, backward, or remain stationary. Although scientists have established waves, the surface layer of water can carry a variety of movements with animals, but the mathematical model is not yet clear. “This is one of the great issues. Although it has not yet been solved, anyone can implement it in a bathtub,†said Dr. Horst, who is responsible for the project. "We were surprised that no one had previously conducted relevant research."
The researchers hope that this study can be scaled up, and their findings can also be used in various display applications, such as for oil spill problems, recycling drift boats, better understanding of tidal phenomena, or people can Go forward easily in the countercurrent. The study was published in the journal Nature Physics.
Dream tech focuses on the smart home appliance industry. The company has four major categories: wireless vacuum cleaners, robots vacuum, high-speed hair dryers, and floor scrubbers, and continues to expand in personal care, life and other fields. Its first product, the wireless vacuum cleaner V9, was launched on Xiaomi Youpin crowdfunding in 2018. In March of the following year, it logged on to overseas e-commerce platforms such as AliExpress, eBay, and Amazon, officially opening the global channel layout, covering China , the United States, France, Poland and more than 100 countries.
