[9/30: ADDENDUM: I am becoming more serious about trucking ahead with my muon blanket experiment!]
I wish you could just Apple-C Apple-V what you're looking at into a notebook.
There is a unique feeling associated with writing in a physical journal. Writing by hand can help you process thoughts more clearly and think more spontaneously. But I crave an easy way to paste in a photograph of whatever I am looking at.
Unfortunately, this is an incredibly tedious process! You must leave an empty space in your journal, take the photo with your smartphone, and then later on in the day you must remember to bring your smartphone (and cord) to a printing shop, print the photo, bring the photo home and paste it in. What a pain!
