Of Particular Significance

Category: Uncategorized

I’m very pleased to report that “Waves in an Impossible Sea“, my book about the universe and its secret role in every aspect of daily life, has been selected by the Wall Street Journal as one of “10 Books to Read Now: Science and Technology”.

The full list and the reviews are behind a paywall, but you can see the titles of the books even before the paywall. The other nine are:

  • Supremacy, by Parmy Olson
  • Escape from Shadow Physics, by Adam Forrest Kay
  • Putting Ourselves Back in the Equation, by George Musser
  • Count Down, by Sarah Scoles
  • Magic Pill, by Johann Hari
  • Superconvergence, by Jamie Metzl
  • The Afterlife of Data, by Carl Öhman
  • Read Dead’s History, by Tore C. Olsson
  • Who Wrote This, by Naomi S. Baron

Ten books to keep our minds active and up-to-date! We all have some reading to do…

What? There’s a comet coming?

In fact, it’s already here. Oh yes, it seems that 2024 may not just be the year of a terrific solar eclipse and spectacular outbursts of northern lights (and maybe, just maybe, a nova.) In morning twilight, if you live in the right latitudes, an ever-brightening comet can apparently be spotted right now. I haven’t seen it yet, but I’m hoping to get a chance.

Nothing in cometary life is guaranteed; comets can fall apart unexpectedly, or fail to brighten as expected. So far, though, Comet C/2023 A3 Tsuchinshan-ATLAS is looking promising; its tail may soon be longer than its name.

As promised, the audiobook for Waves in an Impossible Sea, read by Christopher Grove, has finally come available. You can find it on Audible and on many other platforms. (Click here to order the audibook, hardback, or e-book.)

To help make the text easier to follow, I’ve put the 50+ figures, the 6 tables, and the glossary on-line. You might, for instance, choose to have them open on your phone for easy reference while you’re listening. (The endnotes are also there too, although my understanding is that Mr. Grove won’t be mentioning them as he reads, so you may need the text to make them useful.)

There are additional resources for readers already up on this website, supplementing the book, and more are coming soon, so please make use of them. Also feel free to ask me questions if you find yourself confused — and please don’t be embarrassed to do so, because the universe is confusing… even to physicists. No question is too simple; in fact, the simple ones (what is empty space? what’s a particle? why don’t we feel the Earth’s motion?) are often the hardest to answer.

Back in April 2022, the CDF experiment, which operated at the long-ago-closed Tevatron particle collider. presented the world’s most precise measurement of the mass of the particle known as the “W boson“. Their result generated some excited commentary, because it disagreed by 0.1% with the prediction of the Standard Model of particle physics. Even though the mismatch was tiny, it was significant, because the CDF measurement was so exceptionally precise. Any disagreement of such high significance would imply that something has to give: either the Standard Model is missing something, or the CDF measurement is incorrect.

———-

Still waiting for a possible outbreak of auroras (northern/southern lights) tonight; a tremendous blast from the Sun, launched from a sunspot two days ago, is believed likely to make a glancing impact on the Earth, and to do so within the next 12 hours or so. That means a possibility of bright northern lights tonight if you’re north of, say, New York City’s latitude.

BUT always keep in mind that forecasting auroras is part science, part art, part luck. Our chances are decent, but the forecast can always be wrong.

As far as timing, the best way to monitor what’s going on, I’ve found, is to use https://www.swpc.noaa.gov/products/ace-real-time-solar-wind and look for sudden activity in multiple data channels. If that happens, then the ACE satellite (about a million miles away) has detected a sudden change in the solar wind, and a geomagnetic storm is likely to start at Earth within an hour or so.

Whether you will see auroras or not during the storm depends on how powerful it is, which determines how far from the poles the auroras will reach and how bright they will be. While the forecast is for a strong storm, we’ll just have to see…


At 2300 UTC (about one hour before this posting) you can see jumps occurred in many channels below. That means that the solar storm may begin right around now (0000 UTC, 8 pm New York Time)
