Celeste Solum will blow your mind on what all they are doing. Tracing devices on the Testing swabs, HIVEmind technology in lighting of streets & such connected to all the Satellites sent up & so much more.
I recommend everyone search her interviews. She still has access to websites from her days at FEMA.
My heart sinks at the possibilites, but then I realize the White Hats are in control.
Here is one of her interviews, but more on other maniacal devices & BS they have spent our money to develop to kill us all off, if not fit for slaves.

Great reply. 👍🏻

There is no strong distinction, however, between optical physics, applied optics, and optical engineering, since the devices of optical engineering and the applications of applied optics are necessary for basic research in optical physics, and that research leads to the development of new devices and applications. Often the same people are involved in both the basic research and the applied technology development, for example the experimental demonstration of electromagnetically induced transparency by S. E. Harris and of slow light by Harris and Lene Vestergaard Hau.

Researchers in optical physics use and develop light sources that span the electromagnetic spectrum from microwaves to X-rays. The field includes the generation and detection of light, linear and nonlinear optical processes, and spectroscopy. Lasers and laser spectroscopy have transformed optical science.
