Zooniverse is one of my absolute favorite websites- a citizen scientist's paradise. I don't think I'm so good at analyzing cancer cells, determining the diameter of a cyclone's eye, determining the shape of galaxies imaged by the Hubble Telescope, or spotting solar flares. I also get frustrated categorizing bat and whale vocalizations. I've tried, and I can't even tell what I'm seeing or hearing. More power to those who can.
I'll write soon about four projects that I love involving WWI British Navy weather logs, sea life, pictures of the Serengeti, and ancient Greek papyrus fragments. At the office instead of playing spider solitaire and 3d mah jongg exclusively, I work on these when I need a break from my spreadsheets. I use my brainpower for good while seeing interesting artifacts and amazing animals.
