“Bipedalism freed up the arms and especially the hands for other tasks such as tool-making, creating art and music, all of which was enabled and fostered by increasingly larger brains,” writes Dr. William Brown.

“Human society is like chimpanzee society — tribalistic and prone to violence. A list of conflicts from world wars to endless regional conflicts and violence within our own country makes the point,” writes Dr. William Brown.

“No wonder some dogs hang out with other dogs and humans who might offer companionship, safety, warmth, food and water. Wouldn’t we in similar circumstances?” writes Dr. William Brown.

“The whole experience was much better than commercial flying. We could see migrating birds in season, the unfolding country we were crossing, and overall travel times rivaled commercial flying,” writes Dr. William Brown.

“If controlled fire was a huge plus for neanderthals 400,000 years ago, how far back does controlled fire go?” writes Dr. William Brown.

“These days, the nature of consciousness is hotly debated by several competing groups, with no consensus or clarity emerging in the debates between them,” writes Dr. William Brown.

“Driving everything in my quest for understanding nature have been recuring themes for me,” writes Dr. William Brown, citing the universe, human evolution, the rise of AI and more.

“Colonizing Europeans often encountered what they considered primitive peoples,” writes Dr. William Brown. “Yet, within a few generations, those so-called ‘primitives’ mastered European languages, cultures and technologies.”

“My guess is that had AI been trained on similar challenging math problems, it wouldn’t have taken long before AI mastered other questions posed by top notch mathematicians,” writes Dr. William Brown.

“The picture of human evolution, and indeed the evolution of most species, may look very different by the mid-century mark and beyond. That’s what makes the story so intriguing for me,” writes Dr. William Brown.

“The evidence that neanderthals created art has important implications and suggests that symbolic thinking antedates the emergence of modern humans by several hundred thousand years,” writes Dr. William Brown.

“There are limits to what we can know, given that estimates suggest that 95 per cent of the universe is beyond what we can see,” writes Dr. William Brown.

“It’s common enough when we’re worried or upset for our feelings to be accompanied by an increase in heart rate, perhaps even a skipped or extra beat … But what if, as some scientists suggest, the opposite happens?” writes Dr. William Brown.

“It’s not hard to understand why our ancient ancestors might have created stories to explain and cope with the natural world that surrounded them,” writes Dr. William Brown.

“Here was an example of the evolution of a novel technology in the hands of the three laureates in chemistry who reimagined how atoms and molecules might be arranged to the eventual advantage of humankind,” writes Dr. William Brown

“AlphaFold2 was like a loyal grad student who learned under the tutelage of humans at Google — not human of course, but a student nontheless and perhaps deserving of a share in the prize,” writes Dr. William Brown.

“Sure, there are lots of shortcomings and even mistakes with AI, but given improving databases and computational methods, AI continues to rapidly evolve. The potential for AI to do so is enormous,” writes Dr. William Brown.

“Our fate is not dictated by the sum of all the diseases we develop in our lives, especially in the later decades of life,” writes Dr. William Brown.

“Over the last six years, I’ve witnessed their hard work, dedication and faithfulness to care for their charges much as they would their own. That’s been a privilege to witness first-hand, and never more so than in Jan’s last few days,” writes Dr. William Brown.

“Is AI intelligent? Sure. It is, and becoming as intelligent or more than most humans. Is AI sentient? Not yet, but on the way. And it won’t be long,” writes Dr. William Brown.

“Diminishment, the loss of abilities which we take for granted … comes to all of us in different ways and times. It’s how we manage that diminishment that counts,” writes Dr. William Brown.

“All models are provisional and, even if based on the best data available, might have to change in the light of new evidence,” writes Dr. William Brown.
