“The single most important technical development to have a major impact in commercial and military aviation after the war was the development of turbine jet engines,” writes. Dr. William Brown.

“Like the human brain, AI acquires large databases (sets for AI), which cover a broad range of subjects sequestered in different sets. The issue is: how does AI choose from among different sets of data to better focus and solve the problem or question at hand?” writes Dr. Brown.

“Connect the dots and look back; it seems Biden obvious was suffering from some form of dementia, which affected his memory, speech, thought processes and planning — made worse by the bad news piling up on his desk and pressure at home and abroad to look ‘in command,'” writes Dr. William Brown.

“As it is, the health-care system is overloaded. Physicians and patients alike are frustrated with long waiting periods to see physicians and nurse practitioners.

In week three of this five-part series on the Middle Land, we examined how life began and evolved and the life cycle of stars, including the creation of heavier elements in the cores

In this third instalment in a five-part series on “Middle Land: worlds beyond our senses,” our attention shifts. Beyond the dazzling worlds of physics and astronomy lay the equally intriguing and far more

Last week, in the first of this five-part series “Middle Land: worlds beyond our senses,” the focus was on the events surrounding the beginning of the universe. This week, we switch to the

When I wrote my book “Perspectives” in 2015, I hoped to explore how the world we live in might be viewed from the perspective of Earth’s place in the universe, the origins of

Some form of artificial intelligence had been imagined by fiction writers in the 1800s and the first half of 1900s. But it was Alan Turing, a mathematician and computer scientist, who in the
