The change in foreign exchange rate res...
Recently, scientists used laser gyroscopes to measure that the change in Earth's rotational speed is less than one millionth. This technology can help scientists understand the complex flow of water and air, which can cause the smallest adjustments to the Earth's rotation.The Earth's rotation is not completely stable. Planets accelerate or slow down as they rotate, slightly shortening or prolongin...
It is reported that the National Institutes of Sciences (INRS) of Canada has developed a camera platform that can achieve cheaper ultra fast imaging through the use of ready-made components, which can be used in various applications.This new device aims to address some of the limitations of current high-speed imaging, including parallax errors and potential damage from pulse illumination. Th...
The use of lasers in space is a reality. Although radio waves have been the backbone of space communication for many years, the demand for faster transmission of more data has made these lighter, more flexible, and safer infrared rays the future of space communication.Recently, WipThermal is a European project dedicated to developing groundbreaking solutions for wireless energy transmission in the...
When observing biological samples under a microscope, if the medium in which the objective lens is located is different from the sample, the light beam will be interfered with. For example, when observing a water sample with a lens surrounded by air, the light bends more strongly in the air around the lens than in water.This interference can cause the measured sample depth to be smaller than the a...
