Nuclear Tweet

As I wrote to Susan on election night:

“The world has forgotten how terrible nuclear weapons are; I fear that our odds of repeating that lesson may have greatly increased.”

In this tweet, I see confirmation of that fear.…/status/811977223326625792

The president-elect appears to aspire to power in many forms. Nuclear weapons are, indeed, powerful, but they have consequences that are both grave and long-lasting. A full nuclear exchange is something that no country in the world can bear. Continue reading



We skied this Thanksgiving, as we did last year, in Canada. It snows there, you see, and it does so earlier there than it does here in the states.

Holy moly, did it ever snow this year. It snowed enough to open Whistler early, and then it snowed a lot more.

We got up there Friday morning, and found ourselves waiting in impressive lift lines. More than an hour after entering our first line, we got to ski. It was clear that the snow was drier and deeper than we’d thought; two lifts later, it was much deeper than we thought, and the hunt was on.

Whatsoever Things

One of my favorite pieces our high-school director selected for our symphonic band was ‘Whatsoever Things‘, composed by Mark Camphouse. It has everything a young trumpet player could love: drama, risk, depth, wide dynamic range, beautiful brass chorales, and, critically, soaring solos.

While the score shaped my musical life, what’s mattered more in adult life has been the title. Whatsoever Things are the first two words of a biblical passage, Phillipians 4:8. Though I’m not religious, it has stuck with me since.

Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.

In both science and personal life, I generally shorten it in my mind to, “Whatsoever things are true, … think on these things.”, but the full passage has more to say. It is a dogged pursuit of things that are true that seems to guide my work, even when it comes at a cost.

Tonight, too many times this year, ‘whatsoever things’ resonates.

Debbie Jin

At the celebration for David Thouless’ Nobel Prize today, a few of us got sad news, which we hadn’t yet heard.

A few weeks ago, the world lost Debbie Jin, one of the most accomplished experimentalists of our time. Shining among those accomplishments was the first Fermi condensate, for which she might have won her own Nobel.

I’ll remember her more, though, for the kind and thoughtful evening she spent with a gaggle of interested graduate students over dinner at Cedars.

It was far too soon; she will be deeply missed for decades to come.


A week ago, I touched the casing of a B-61 nuclear weapon, an object created by humans with a yield as much as 20 times that of the bomb dropped at Hiroshima. It’s as large in diameter as a big dinner plate, and twice as long as a water heater.

The Mountain Hardware Chuter 15, with added zippers and stitching

The Mountain Hardware Chuter 15, with added zippers and stitching

I am impressed by Andrew McLean’s designs. They’re practical; some break new ground. He’s not afraid to depart from convention to reach practical solutions.

I’d been considering the Chuter 15 ski pack as a functional step up in a small pack. Andrew’s post tipped the scale; I nabbed the last (?) retail Chuter available online. How better to explore a designer’s vision of the ultimate ski pack than to try it? After modifying the pack to correct a major flaw (hence ‘SuperChuter’), it’s the pack I hoped it would be.
