Breakthroughs in physics 2023

So, how has physics been this past year? Let’s start by taking a look at Physics World. In an article dated 7th December 2023, online editor Hamish Johnston said this: “Physics World is delighted to announce its top 10 Breakthroughs of the Year for 2023, which ranges from research in astronomy and medical physics to quantum science, atomic physics and more”. He went on to say the winner will be revealed on 14th December. Sounds good. So, Hamish, what have you got? 1.  Growing electrodes inside living…

Do black holes have singularities?

I think Roy Kerr’s recent paper is important. It’s called Do black holes have singularities? I think it’s important because it challenges an orthodoxy that’s been taken for granted, and because Kerr has the authority to get some attention. That’s because he was in on the Golden Age of General Relativity, and because the EHT collaboration described both M87* and Sagittarius A* as matching the Kerr metric. To set the scene, black hole physics has been around for a long time, but a major development was…

The Tomorrow War

I’ve always liked science fiction. I can’t explain why. I just do. When I was a boy I’d go to the library and bring home yellow-jacket Gollancz science fiction books to read. When I was a teenager I’d buy paperbacks from the bookshops. I have about a thousand science fiction books on the shelves in our back room. We call it “the library”, but there’s also an electric piano, a sofa, and a seventy-inch TV. The “library” It’s my favourite place for watching movies. I don’t…

The Nobel prize in physics 2023

There have been some dreadful events in Israel, with terrorists going door to door killing women and children, and more. Meanwhile sections of our media and community refuse to condemn such acts, and call the perpetrators “militants”. Such is the corruption in our society. As I was saying last time, honesty and decency are in short supply, so it’s no small wonder that so many people are suffering. These are troubled times, so much so that the trouble with physics is left in the shade. For…

Nature and corruption

There was an important news story in the Telegraph last Thursday: Climate scientist admits overhyping impact of global warming on wildfires to get published. It was written by Sarah Knapton, the Telegraph science editor, and it featured a climate scientist called Dr Patrick T Brown. He’s a whistleblower, and I totally applaud the guy. He was referring to a paper he co-authored that was published in Nature. It was called Climate warming increases extreme daily wildfire growth risk in California. Nature cover, Volume 621 Issue 7977,…

The psychology of belief

Many years ago I wrote an article called belief explained. You can find a 2007 version of it on a website called scienceforums.net. A development of that was an article called the psychology of belief. You can find a 2010 version of that on a forum called ILovePhilosophy.com. I wrote it because way back in about 2006, I realised that I believed in things for which there was no scientific evidence at all. I don’t just mean things like religion and politics. I mean things in…

The race to invent new particles is pointless

Sabine Hossenfelder had an article in the Guardian last month. As you will doubtless know, she’s the author of the Backreaction blog. It used to be a physics blog with a bad reputation for comment censorship. Now it’s a YouTube blog, and there are no comments*. That’s because Hossenfelder is a “follow me on Twitter” type who talks at you, not to you. She’s never been interested in what anybody had to say. Moreover it’s crystal clear she’s never read the Einstein digital papers or the…

Physics is dead, long live physics

I was pleased to read about the launch of the James Webb space telescope on Christmas Day. I do hope everything goes smoothly. It will take about a month to get on station, about three months before it’s cold enough to function, and about six months before it’s commissioned. Unlike Hubble, which was in a low Earth orbit, Webb will be in a “halo” orbit around the L2 Lagrange point a million miles from Earth. Along the way there are 3 burns and 50 deployments with…

The leptoquark hype

There was an article in The Daily Telegraph last week. The title was Key step to unlocking mysteries of the universe. The subtitle was Hearts ‘set racing’ at site of Large hadron Collider as experiments hint at a new force of nature. You can find an online version at Key to how universe works may have been discovered. Both the print and the online versions were written by science editor Sarah Knapton, and whilst the title and illustrations are a little different, the content is the…

The trouble with physics

Many years ago I gave evidence at the Old Bailey. It was a fraud trial, and I was an expert witness for the prosecution. During the case I got to know DI Frank Cooper of Holborn nick. He told me about his "copper's nose", and what bank robbers and the like are really like. He said I shouldn’t think of them as lovable rogues like in the old movies. He said “They’re career criminals, they’re contemptuous of people like you”. Or words to that effect. Along…
