Mural in the Life Sciences Building
I like the rat with the big brain, upper right. Enlarge, for greater definition.
I have passed this building on my morning walk many times without ever trying to enter. (Many of the campus buildings are closed except to those with a key.) Today I realized that this one is open, and I went in for a short walk around. This mural is in the entry lobby.

Visualizing the chemical composition of Earth's crust was done through scaling the volume of each sphere according to the mass each element relative to the total mass.
The mass of each element in Earth's crust is printed in the bottom right corner in parts per billion by mass.

Many of our summer activities are connected to playgrounds as the children are at that age where playgrounds still provide activities. One thing Aura loves to do is, of course, swinging, and in today's picture she is swinging with her friend Linnea (at the front). If you have children of your own and they like to swing, you certainly know how unbelievable hard it is to photograph a swinging child. First of all, the swing itself is often challenging to approach with camera because of its physical shape. No matter what angle you take, it often produces certain kind of leading lines which are distracting one way or another. Which looks, at first, a simple shape, turns out to be something very different as it seems to ruin any compositional approach what photographer can come up with. And if you solve this compositional mystery somehow with luck, there's of course the swinging movement which makes any further approaches downright impossible as the subject keeps on moving back and forth, and effectively changes the composition all the time. On top of this the back and forth swinging also introduces technical problems as it is not given at all that the camera's autofocus can track it and deliver sharp pictures even if you manage to solve those earlier problems. Like I said, it's surprisingly difficult subject to photograph which has surely bemused me.
But here's one way to solve this which includes the use of Batis 2/25 electronic depth of field scale (though this method can be reproduced with any lens that has some sort of depth of field scale). To get rid of compositional problems I wanted to get real close to Aura and Linnea with this picture, and effectively cut out the distracting structures of the swing it itself. I also wanted to use zone focusing for this picture, because that way I could forget focus locks, points, trackings and all that AF-stuff, and concentrate on a situation itself. So I switched to manual focus mode, chose aperture of f/8 and put the sensitivity to 800 to be able to freeze the moment with high shutter speed (1/1600 sec in this case). Then I used the Batis oled-display to set my focus point to 1,0 meter, which gave me 46cm deep depth of field. Using the electronic depth of field display and its digits it is very to dial in relatively precise depth of field. Then knowing that my focus point was at 1.0 meter and depth of field approximately 23 cm front and back of that point, I just pointed the girls when they came up within that distance and shot with rapid fire to capture as much as I could. Going up close with this method is ridiculously easy as I could, at the same time, play with the girls and still get nicely focused shots. In the matter of fact, I made them laugh by playing that I couldn't look their swinging as they were swinging so wildly (not really). Within this play I covered my eyes with the other hand as I shot short rapid burst with the other – something I couldn't have done if I had worked with autofocus. Zone focusing is, in the case of swinging, much more effective method than any autofocus could ever be, and it reminds, at least me, that not everything is something that needs to be solved by 'better technology'. Very happy with this picture as it seems to catch the spirit of the moment so nicely.

So this is my favourite moment of Frocktober so far. A couple of weeks ago I took my flouncing around in frocks to a couple of local art events. And at one I met Dr Susan Hayes! All right, she's not incredibly famous, but she lives locally, and is a facial anthropologist responsible, amongst other things, for the reconstruction of the features of Flores Man (Homo Floresiensis), also known as 'The Hobbit'. So I went full nerdy fangirl on her, and we did a selfie. She's a lovely lady, and it was a real pleasure to meet and chat to her. That's some of her art on the wall behind us and she is, of course, holding a reconstruction of The Hobbit's skull.
I think a lot of what I admire about her is that she sits on the boundary of art and science, and that's not something enough people do.
And that story is surely worth a donation to our Frocktober fundraiser. You can do it here: www.mycause.com.au/page/185933/it-has-pockets

Photos from the March for Science in San Francisco, California, on April 22, 2017. Definitely the smartest signs of any protest I've ever seen.
As a science teacher back to school = back to work. I wanted to do a picture of a single tear in the corner of my eye reflecting my sorrow at the demise of summer. Unfortunatly I could not manage a single tear and anyway I could not hold the camera steady through the sobs.
Oh well back to seeing the world through test tubes and kids.
bye sunshine (hi Duna). 5.8km descending at 5m/s we have 2h 37m of battery life so no worries on lack of solar power

Computing Sciences hosted 14 local high school students as part of an outreach program to introduce students to various career options in scientific computing and networking. The sessions include presentations, hands-on activities, and tours of facilities. The program was developed with input from computer science teachers at Berkeley High, Albany High, Richmond's Kennedy High, and Oakland Tech. Computing Staff present a wide range of topics including assembling a desktop computer, cyber security war stories, algorithms for combustion and astrophysics and the role of applied math.

Next time I will pay more attention to the lights. LOL
