I often joke that I have the support of carpark fairies. I ALWAYS get a park were I need it. Indeed, I couldn’t tell you the number of times I have gone somewhere new, and decided to just park somewhere, and work it from there… only to find I am parked right outside the place I needed to be.
But something just happened, that has left me seriously sitting here thinking “What.. I mean .. what?”

Complete solar eclipse today (21 August, 2017) in Oregon, just a little south of here. Seattle/Bellevue got 92% eclipse apparently. So, when the sun darkened a bit, I popped out to see. Fantastic day for it, not a cloud anywhere. And we are surrounded by trees, sun just high enough to be peeking through the top branches.
There on driveway, a bunch of people trying to look up at the sun, half blinded. A couple had “eclipse glasses” and one had rigged a pinhole box. But the pinhole was too close to the eyeball, so when she tried to see, she blocked the hole :). All this, while standing half in shadow of a broad leaf tree. I could hear the comments about “not really much to see”, etc.
I wandered down and pointed to the ground, asphalt, and the garage door (white) behind them. There in all its glory was the eclipse for everyone to see. The sun/moon shining through the leaves created myriad pinholes, every one creating a (reversed) image of the eclipse. Against perfect grey or white background. You can clearly see the remaining disk of sun against the moon.
Looking directly was “OK” through the smoked glass, but not really all that interesting. On the other hand, the crescents were all over the ground. It was like being IN the eclipse. WAY better than “eclipse glasses”, pretty cool.
I include shots direct of sun around 10:33 (peak coverage was 10:26), tiny slice out of the side, but could still see the crescents on the road/wall.
I just love how optics is so counter-intuitive sometimes 🙂 🙂
Yes, just in time for Christmas, the new edition is available right now!
Its better, stronger, faster, able to leap taller buildings with less of a run-up and not be left panting so hard afterwards!
And its an even BETTER read! (I know, hard to believe, right). Basically because, like everything, practise is the only way to get better.

Momentum 2nd edition is just days away!!
Momentum is the first novel I wrote, and I was pretty staggered at just how much blinking work is involved! Not that I wouldn’t have done it had I known, but there is really a LOT of details to sort out.
The writing is still very much the lion’s share, of course. But somehow I thought: right done that, now a miracle occurs and everything would be sorted: the cover, the publishing, and of course: the readers.
Not as such. Sadly. Continue reading Momentum: Edition 2
Ok, for a change in pace from momentum for a moment, Consider the good old light speed limit. Now I am not going to get into whether on not some tiny subatomic particle can do something weird and interesting only to physicists with nothing better to worry about, and a HUGE research budget.
Lets think about a macro example, something that at least in principle “anyone” could actually do, and see. Continue reading Scissors faster than light
Ok, we have null momentum. But… see there’s this wee issue called, umm, conservation of energy. And as wee issues go, it’s not so wee.
Its basically all of physics in a nutshell.
If energy even LOOKS like it’s not going to be conserved, the universe says “NOPE. Not gonna happen.”
Ah, yes, I can see the issue. But look, universe, I click this and (with no fanfare at all) momentum stops being the rotten little anal-retentive, every column has to add up, universe auditor (in a Terry Pratchett sense). And things just happen. Continue reading Conservation of energy
