Panasonic has announced the launch of two new laser projectors

Nikon Vision, a subsidiary of Nikon Corporation, is pleased to announce the launch of the COOLSHOT 20i GIII laser rangefinder for golfers, which is Nikon's small and lightweight model in the COOLSHOT series.While maintaining the lightweight and compact size of the COOLSHOT 20i GII, the new model notifies users through brief vibrations that the distance to the flagpole has been measured.When measur...

The gravitational wave background was first detected in 2016. This was announced after the release of the first dataset by the European pulsar timing array. The second set of data has just been released, combined with the timed array of Indian pulsars, and both studies have confirmed the existence of the background. The latest theory seems to suggest that we are seeing a comprehensive signal of th...

Rydberg atoms and molecules are characterized by having one or more electrons in highly excited bound states. Such atoms and molecules are said to be in “Rydberg states” and are also called “hollow” atoms and molecules. Rydberg states are useful for studying various phenomena arising in intense light–matter interaction that involve electronic excitation with an intens...

Researchers from the New Materials Technology Research Institute of Beijing University of Science and Technology and the Beijing Modern Transportation Metal Materials and Processing Laboratory reported a review of high-throughput preparation of alloy composition design in additive manufacturing. The relevant research is titled "High throughput preparation for alloy composition design in additive m...

A team led by Professor Ye Dexin and Professor Chen Hongsheng from Zhejiang University, as well as Professor Yu Luo from Nanyang University of Technology, conducted practical research on full parameter transformation optical devices. The research team has designed and implemented an all parameter omnidirectional invisibility cloak based on the theory of linear transformation optics and omnidirecti...
