Scientists have been attempting to come up with an equation to unify the micro and macro laws of the Universe; quantum mechanics and gravity. We are one step closer with a paper that demonstrates that this unification is ...
Symmetry has been one of the guiding principles in physicists' search for fundamental laws of nature. What does it mean that laws of nature have symmetry? It means that laws look the same before and after an operation, similar ...
Construction is literally a hands-on business where profit-loss margins are squeaky-tight. The training of new workers requires time and labor, and materials like wood, cement, and rebar are too expensive for the "play" essential ...
By combining a compressive sensing algorithm with a digital holographic microscope, Prof. Shih-Chi Chen of the Department of Mechanical and Automation Engineering, Faculty of Engineering, The Chinese University of Hong Kong ...
Walking, talking holograms have been a staple of sci-fi films since Princess Leia was magically brought to life in "Star Wars".
Researchers have developed a new printer that produces digital 3-D holograms with an unprecedented level of detail and realistic color. The new printer could be used to make high-resolution color recreations of objects or ...
Metasurfaces are optically thin metamaterials that can control the wavefront of light completely, although they are primarily used to control the phase of light. In a new report, Adam C. Overvig and colleagues in the departments ...
Today's state-of-the-art analysis of biological samples by light microscopy includes a vast variety of techniques ranging from conventional bright field microscopy and phase contrast microscopy to high resolution confocal ...
Physicists and materials scientists have developed a compact optical device containing vertically stacked metasurfaces that can generate microscopic text and full-color holograms for encrypted data storage and color displays. ...
Researchers have developed advanced optical security features that use a two-piece metamaterial system to create a difficult-to-replicate optical phenomenon. Metamaterials are engineered to have a property that is not found ...
