Whence the arrow of time?

[“Quantum foundations” series] A physicist walks into a bar, and asks the bartender, “What time is it?” The bartender is about to reply but then recognizes the customer. “You’re a physicist, correct? So, it’s a trick question.” So, what’s with time? A venerable philosophical question. A foundational question in physics. We have electronic devices, extremely… Continue reading Whence the arrow of time?

Quantum reality, quantum worlds – new book explores quantum foundations

[“Quantum foundations” series] [Updated December 2019] Introduction to this topic If Murray Gell-Mann was right that Niels Bohr brainwashed a generation of physicists to accept the Copenhagen Interpretation, either his influence has waned or he didn’t do a very good job in the first place. For in an informal poll conducted at an international meeting… Continue reading Quantum reality, quantum worlds – new book explores quantum foundations

Celebrity and cultural phenomenon — Stephen Hawking

Stephen Hawking died last week. Lots of tributes in the media about his scientific legacy and life. Sean Carroll posted an article on his blog on March 16: “Stephen Hawking’s Scientific Legacy.” It’s particularly interesting. As a career physicist and cosmologist, Carroll met and interacted with Hawking over the decades. Early in his career Carroll turned… Continue reading Celebrity and cultural phenomenon — Stephen Hawking

While examining my Kindle library yesterday, I started reading a sample of Art Hobson’s 2017 book Tales of the Quantum: Understanding Physics’ Most Fundamental Theory and then became interested in his background. A Google search found biographical information, references to his books,… Continue reading Point particles RIP

“Star man” as rock star

My meditation on our common sense, everyday experience of physics and the 10^n and 10^-n reality was facilitated by MSNBC this morning — there was a segment with Neil deGrasse Tyson promoting his latest book, Astrophysics for People in a Hurry. A brief Q&A offered some additional context and memorable quotes. For example, Galileo’s famous quote that “The… Continue reading “Star man” as rock star
