Why dust collects on fan blades [Apr. 4th, 2017|08:26 pm]
tobo
»The properly skeptical reader may have detected a peculiar assumption in our demonstration of viscosity: the fluid must stick to the walls of the [container] rather than simply slide along the walls.

Now fluid certainly does stick to itself. If one tiny portion of a fluid moves, it tends to carry other bits of fluid with it—the magnitude of that tendency is precisely what viscosity is about. Less obviously, fluids stick to solids quite as well as they stick to themselves. As nearly as we can tell from the very best measurements, the velocity of a fluid at the interface with the solid is always just the same as the solid. This last statement expresses something called the "no-slip condition"—fluids do not slip with respect to adjacent solids. …

[A] peculiarity of this no-slip condition is that the nature of the solid surface makes very little difference. If water is flowing over a solid without an air-water interface to complicate matters, the no-slip condition holds whether the solid is hydrophilic or hydrophobic, rough or smooth, greasy or clean. The nature of the solid surface matters only when we have a liquid-gas interface present as well—in short, where surface tension becomes a factor."

The no-slip condition has a number of important ramifications. In particular, it means that any time a fluid flows across a solid, a velocity gradient is present. … In practice, the no-slip condition explains (in part) why dust and grime accumulate on fan blades, why pipes (including blood vessels) encounter trouble from accumulation of deposits rather than from wearing thin, and why a bit of suspended rock is needed in water for the latter to become effectively errosive. … Alternatively, just consider why dishcloths and mops are so much more effective for cleaning than any mere rinse.«

coffee insomnia [Jul. 15th, 2016|02:16 am]
tobo
* post brought to you by afternoon-coffee induced insomnia

things that happened recently:

- saw simone giertz and mary roach at nerd nite east bay. they are amazing. with maria, and co-workers sophie and onath.

- i saw the glorious strandbeests at the exploratorium, and also saw adam savage (of mythbusters fame) in person, as he demoed a strandbeest-inspired creation. (with ben berry, and we ran into paula, and rosanne and justin)

- with maria, and nicholas and diane, and a guy from chaos who chose for himself the american-name "Hemingway", to the "arroyo seco", an entirely misnamed Shangri-La of swimming holes in the viscinity of Gilroy in the Ventana Wilderness, a place of much mystery and intrigue, to which we must return.

- conor came to visit, my former co-postdoc from hannover. i took him to the mission, we ate delicious mexican food at taqueria can-cun. we washed it down with beer on the ferry back to alameda, then joined my housemate's birthday party. on sunday I lead a hike up mount tam, where we stopped at the west point inn for a pancake breakfast two miles in.

- oh yeah also I went to munich, austria, and slovenia. maybe I should tell you about that? favorite thing: the eisbachwelle. and beautiful lake bled, and swimming in the adriatic at piran (slovenia).

- at my work yesterday we had an hour-long fitness class. only six people showed up, but it was super fun, and now I hurt everywhere.

upcoming:

- going to a burlesque cabaret circus thing tomorrow, here in Alameda in a circus tent on the taxiway.

- And then this weekend, with my co-workers I'm going camping out in the Sacramento river delta, on Tim Anderson's land, which is a sort of beautiful swampy junkyard, and we will swim in the river and maybe take a boat to visit Ephemerisle.

- bryce and robin's wedding, near eugene oregon, in august. and then my uncle mike and andrea, at their house out in the high desert near lake tahoe (loyalton ca).

Today in my job at Google: eight hour wilderness first aid training.

I believe this is somewhat unusual.

Hey, I won a prize! The "Breakthrough Prize" -- which I had never heard of before, but which is being touted as some kind of new Nobel Prize -- was just awarded to the three inventors of LIGO and the 1000 authors of the discovery paper. My share of the prize is approx $2000.

I want to donate it... Who would be a worthy and impactful recipient? Something about STEM education.

Today was a good day! In my present state of contentment, all days are good days.

I was rated "exceeds expectations" in the company's semiannual performance reviews, which pleases me greatly. My ambition is to try to get promoted in the next round.

I've found a nice niche as flight director during our flight test days, and have been putting in some long hours in our flight-test campaign, which has been ramping up. And there are other work-adventures, too. Last Thursday the company put me on a charter airplane, an eight-seat Pilatus PC-12, with five of my co-workers, for a daytrip to a remote field site.

This afternoon I stopped at public library down the street, signed up for a library card, and checked out the Lonely Planet for the Philippines. Maria and I are scheming up a trip over Christmas to her native land.

This upcoming weekend we might make another expedition to the Steep Ravine hot springs, near Bolinas -- they're in the rocks on the beach and normally obscured by the sea, except for during especially low tides, such as will occur in the coming days. And on a similar note-- a friend has a code for Essex!

Alameda is beautiful, the weather is sublime, and on the weekends I walk five blocks with the dog to the beach and get an ice coffee and then recline on my porch in the sun with a good book. Ryan is moving back to town. I'm helping organize an unusual underground party. I'm excited about camping in the mountains. I want to hang out with Nicolás more, and have barbecues in the park.

Wolfgang Franke

Ehemaliger Inhaber der Gaststätte Kaiser tot

Bei ihm haben viele Generationen von Studenten ihr Bier getrunken und geklönt: Nun ist Wolfgang Franke, ehemaliger Inhaber der Kult-Gaststätte Kaiser am Schneiderberg, Ecke Schaufelder Straße nach kurzer schwerer Krankheit im Alter von 72 Jahren gestorben.

Hannover. In Hannovers Nordstadt, und wohl auch darüber hinaus, ist es momentan das zentrale Gesprächsthema: Wolfgang Franke, ehemaliger Inhaber der Kult-Gaststätte Kaiser, ist verstorben. Er erlag einer schweren Bluterkrankung, ähnlich der Leukämie. Franke wurde 72 Jahre alt.

Fast 40 Jahre führte er die Gaststätte Kaiser am Schneiderberg/Ecke Schaufelder Straße. Arbeiter, Studenten, Professoren, Lebenskünstler und nicht zu vergessen Mahjongg-Spieler setzten sich an die dunklen Eichenholztische in seinem Etablissement, und Franke setzte sich oft für einen kurzen Plausch dazu. „Er interessierte sich für jeden. Der Mann hat eine Aura geschaffen“, sagt Karl Otte, Stammgast seit 34 Jahren.

Über Franke und seine Gaststätte gibt es etliche Geschichten. Viele werden jetzt wieder aus dem Gedächtnis gekramt. Eine geht so: 1995 herrschten auf den Straßen der Nordstadt bürgerkriegsähnliche Zustände. Punks aus ganz Deutschland waren zu den sogenannten Chaostagen angereist und lieferten sich wüste Straßenschlachten mit der Polizei. Franke wollte vermitteln und berief in seiner Garage einen runden Tisch ein. Polizisten, Anwohner und angeblich auch Punks saßen einander gegenüber – und redeten endlich.

Die Geschichte erzählt viel über Frankes Offenheit und seine Menschenliebe. Gern berichtete er Gästen von seinen Reisen in Länder, deren Namen die meisten nach ein paar Bieren kaum aussprechen konnten, etwa Südossetien. Später entdeckte er das chinesische Brettspiel Mahjongg und wurde ein leidenschaftlicher Fan. Eine Urkunde im Kaiser bezeugt, dass Franke an einer Weltmeisterschaft teilnahm – und von 144 Spielern den 142. Platz errang. Bis kurz vor seinem Tod soll Franke noch Mahjongg gespielt haben.

2008 gab Franke das Kaiser in die Hände von Nachfolger Zurab Mikava. „Ich bin für die meisten Gäste immer noch ,der Neue‘“, sagt Mikava schmunzelnd. Franke sei wie ein Vater für ihn gewesen.

patagonia is not a country [Feb. 21st, 2016|11:09 pm]
tobo
Hoofed it to Makani (to pick up my van) after being denied boarding on AC Transit (aka "the bus") for the cause of answering "Yes" to "Is that your pet?" instead of "No this is my service animal." No matter, my pet and I enjoyed the beautiful weather and a two mile walk / exploration of the repurposed Navy base.

Happily my little car was not broken into overnight. I took the battery out and got it recharged at an O'Reilly auto-parts store. Apparently that's a service they offer, and it was super fast, too - less than an hour. Put the juiced up battery back into the car and my new housemate Wayne drove it back to our house.

Next step is to actually replace the alternator belt, which is kind of annoying to do because you have to take off the water pump's belt first... So the water pump and the alternator have to do a little dance to get all the belts in order.

Maria is in Patagonia for ten days, on a trek with her parents. Did you know that Patagonia is not a country? I'm not sure I was entirely clear on the matter and might have confused it with Paraguay. Lest there be lingering confusion, Patagonia is a region of Chile and Argentina.

Dinner with Anisa and Wayne at some place in Oakland's Chinatown.
