A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
This is a science community. We use the Dawkins definition of meme.
You can actually use this, or more generally the shadow of a tree on any sunny day to calculate the distance to the sun !
(Can't seem to find the video demonstrating it, but I have a feeling it's from Physics Girl or Up And Atom on youtube)
The ratio of the size of the image to the distance from the pinhole is the same as the ratio of the size of the sun to the distance to the sun.
