nothing in the universe can travel faster than light. The theory states that as matter approaches the speed of light, the matter's mass becomes infinite. That means the speed of light functions as a speed limit for the wholeuniverse.
DALIAN, Dec. 7 (Xinhua) -- China's first medium-speed high-power ammonia-fuelled engine ignited successfully in Dalian, northeast China's Liaoning Province, marking China's breakthrough in the related key technologies. The ammonia-fuelled engine, featuring low carbon, high safety, and good inte...
In SPIM, instantaneous optical sectioning is achieved by illuminating the sample with a sheet of light and generating fluorescence in a thin slice, which is then imaged with a fast camera. Millimetre-sized specimens can be reconstructed by rotating and imaging them from different sides (multi-...
Metadynamics is a powerful method to accelerate molecular dynamics simulations, but its efficiency critically depends on the identification of collective variables that capture the slow modes of the process. Unfortunately, collective variables are usuall
The first “modern” measurement of the speed of light was in the 1840s by Hippolyte Fizeau. He shone light through the teeth of a quickly rotating cog, off a distant mirror, and back through the cog. If the cog rotated slowly, the light would pass through the same gap. If it was ...
CHANGSHA, May 6 (Xinhua) -- China's first medium-and-low speed magnetic levitation (maglev) line, which is fully supported by its homegrown technology, marks the fourth anniversary of commercial operation on Wednesday. As of Tuesday, the maglev line in the city of Changsha, capital of centra...

Modern lens designs are capable of resolving greater than 10 gigapixels, while advances in camera frame-rate and hyperspectral imaging have made data acquisition rates of Terapixel/second a real possibility. The main bottlenecks preventing such high data
