This image visualizes the discovery of asteroids from 1801 to 2020. The Solar System is shown in a logarithmic scale to allow both the main asteroid belt and Kuiper objects to be shown. Asteroids are shown in the position of their perihelion. This makes it easier to separate the various families.
I also plotted the histogram of how many minor planets were discovered each year, the semi-major axis, and excentricity on the right panels. The left panels show the excentricity and inclination as a function of semi-major axis, this is again to show how the various asteroid families were defined based on their orbits.

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.
The only science/lab equipment in this photo that's actually mine are the lab glasses and the two beakers in the front part of the counter.
Katie, Kyle, and I went to a few abandoned places yesterday, and this was taken at Horace Mann High School in Gary (where the photo I uploaded yesterday was, as well). My science equipment came from my high school. I helped my friend ta for one of the science teachers, so we were always in the back room preparing stuff for classes. So obviously, I was around the extra/old lab equipment that they never used, so I took a few things, haha. I was amazed at how much stuff was left in the school, let alone the lab. They literally just left everything there when the school closed down. There's a room with all of the textbooks alone which I find haunting in a way. But anyways, I always wanted to do a "mad scientist" type photo. I definitely want to visit this concept again in a more mad and frightening type of way.
By the way, I thought on the fly how to make interesting "chemicals": Water and food coloring :3
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
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.
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.

19.2.21... another day, another homeschool science experiment! so far we've made salt crystals, used up half a jar of oil on a lava lamp, grown a hyacinth bulb, investigated viscosity, and today we made pretty colours with skittles! lol.

This table, which I found on the AGU blog (link below) lists words commonly used by scientists, their definition as scientists mean them, and then what the public hears.
