| Over the past year I've been programming some tools used to find the path of fireballs across the sky and get it all automated. The key is to find stars in images, since the stars have known positions, and model the lens to create a mapping between sky coordinates and pixels in the image. I can always check how well the tools do by annotating an image with star positions where they are supposed to be according to the model. And the modelling has recently become quite accurate, approaching arcminute accuracy. Such as in the image below (zoom in). The annotation and grid were created automatically - without any manual guidance.

| I created a lego contraption for testing the viscosity of various fluids.
The main apparatus all set up. I was testing it on molasses to begin with. I love this sort of homebrew science.
Detail of the gear box, those motors spin really fast, which is good because I can turn all that speed into torque using that worm gear.
Along with fezes and bowties, brown dwarves are cool.

| I've made quite a few ships in the ship editor, but since I haven't done any imported models (yet) they've remained scattered throughout several threads. For now, I've decided to create a page for them, here. All my ships (the better ones) are now in one place!

| Very nice! My favorite is the yellow flower. The fungi and (dog's?) eyes are really neat, too.
And, once again, I'm following an Antza post with a mountain climbing post. 
This time I went up a peak that is slightly taller, tougher faster stronger. Lots of stream and waterfall crossings along the way. A lot of loose scree. A lot of steep snow. A lot of breathlessly gazing upwards and wondering "why the heck would anyone climb a mountain?"

This is by far my favorite. (Spruce flower.) 
Those are some nice views. 
I'm planning a trip to Boston area in August. I don't think there is anything so spectacular near there. :/

Unfortunately not, but there are still a lot of really cool things to see, including many of historical significance. It's by no means the prettiest place in the country, but it's far from the ugliest

| Watsisname and Antza2, you are really really good.
Yesterday I made a quick video for an experiment I wanted to do for my Optics Course at Madrid's University. It's about photoelasticity observed with a polarizer.
The video is in Spanish, and it's filmed with a potato, but maybe you can enjoy it

| Photoelasticity is a beautiful part of optic physics. The demonstration with the stretching/snapping tape is great. Very nice vid!

That video was so cool that i wanted to try it out myself.
Not nearly as nice as yours, but this is all i could do with the stuff i had available.

 wow! that was awesome. Yours is way cooler. I recorded the video with a mobile phone and a very bad camera with a polarizer that was quite unclean (I did everything possible to clean it, I promise)
Your camera captures the vivid colors very very good. I liked a lot the ripping apart of that plastic.
Do you mind if I put your video in the description of mine explaining that to demonstrate that the laws of physics are valid everywhere in the universe a finnish friend has repeated the experiment?
Thanks for the interest

| Go ahead
I will probably do a better video when i'm more prepared, but thanks for liking it
