SciFi author and recovering theoretical physicist.

As the number of Amazon reviews of my sci fi novels surpasses 1,000 (at 4 ½ stars), I just wanted to give my thanks (because it’s that time of year) to all who supported my unusual career turn.

I'm very complimented by Guy P. Harrison's endorsement of my time travel trilogy -- One Second Per Second.

The Bezos wedding inspired me to pluck up my courage and take a look at how my books are doing on Amazon. Pretty happy with the results although I see the rule of trilogies at work.

It feels good to finally launch a book, especially the last in a trilogy. I think I know what Asimov felt like.

Einstein, Curie, Gauss and other deceased luminaries brought back to solve the world’s problems was my premise... goes miserably wrong of course. (Really an homage to my heroes from this mathematical physicist turned scifi author.)

It often helps to read out the draft of a conceptually challenging chapter to my pet Shih Tzu. But I seldom take her editorial advice... she's a dog.

My first Bluesky post. Hello!
I'm an ex-theoretical physicist who has now turned to writing sci-fi -- less math.

Nearly interesting fact: It's Rayleigh scattering of light that makes the sky blue.
