Year: 2022

FOOTNOTE. I am at a Synthetic Biology conference in London. All the talks are (matter-of-fact) about creating totally new life forms, totally new metabolic pathways totally new hybrid modular proteins by cut-and-paste, and making novel tissues and organs. We are now conducting directed evolution. Darwin would (possibly) be delighted. We live in exciting times. Very exciting times. View in LinkedIn

MORE SCIENCE KNOWN in the last few years than in the history of mankind. The majority of scientists who shaped the world lived in the last 300 years. And the rate of change of knowledge approaches exponential growth. Remember the urban myth that the weight of science publications would soon exceed the weight of the earth? https://lnkd.in/eHareWj View in LinkedIn

INTERESTING SEQUELAE. "Just as its easy to make a lens that focuses light in space using diffraction, so it is possible to use dispersion to make a lens that focuses in time." https://lnkd.in/eVgKzAT View in LinkedIn

A TIME LENS. "Such a time-lens can be made using an electro-optic modulator, for example, and has a variety of familiar properties. This time-lens can, for example, magnify or compress in time." https://lnkd.in/eVgKzAT View in LinkedIn

TIME CLOAK TO CONCEAL MESSAGES. "A “time cloak” that conceals events rather than objects can hide secret messages through a trick of light, making information invisible to all but the intended recipient. Like an invisibility cloak that makes something disappear in plain sight, a time cloak makes an event disappear in time. It works by manipulating light traveling along an optical fibre." https://lnkd.in/eAbVHjQ View in LinkedIn

SIGNAL CODING. "Application of the temporal cloak system in optical signal encoding and decoding has been proposed. It has been demonstrated that the developed scheme can be applied in optical signal processing and fiber-optical secure communications." https://lnkd.in/eztPSPd View in LinkedIn

COMMUNICATION BETWEEN PAST AND FUTURE. "We apply the methods of transformation optics to theoretical descriptions of spacetimes that support closed null geodesic curves....Through transformation optics, this metric is analogous to a material that in theory should allow for communication between past and future." https://lnkd.in/evYqK4d View in LinkedIn

DARPA FUNDED TIME-LENS. "The researchers created what they call a time lens, which can manipulate and focus signals in time, analogous to the way a glass lens focuses light in space." Inspired by a theoretical proposal by Martin McCall at Imperial College in 2010, “But his method required an optical response from a material that does not exist," which they overcame. https://lnkd.in/e4aJQTV View in LinkedIn

INTEREST IN METAMATERIALS. "The impact of metamaterials is widespread with almost every major organisation concerned with electromagnetism showing interest in this field." https://lnkd.in/eM8vuRF View in LinkedIn

DEFENSE AND METAMATERIALS. "In the last 5 years there has been great involvement of industry and particularly of the defence establishment in the USA who run several multi mullion dollar programs on metamaterials based at DARPA, WPAFB and Sandia." https://lnkd.in/eM8vuRF View in LinkedIn
