Zooniverse is a website that's home to citizen science projects. You can join and participate in various crowd-sourced science projects that include:
- Helping to assemble old Egyptian scrolls
- Recovering worldwide weather observations made by Royal Navy ships around the time of World War I
- Locating ice chunks beyond Pluto's orbit for a NASA probe
- Searching for extra-solar planets
- Classify galaxies in Hubble photographs
- Spot solar explosions and track their path towards Earth
- Catalog the moon's surface
There's a few more there that I haven't bothered listing. The site is an amateur science geek's paradise.
I fiddled around with the Ancient Lives Project a little. This project is meant to assist in assembling Egyptian (written in Greek) scroll fragments for translation. You get a fragment which you can rotate until you think it is right-side-up. Then you mark the center of each letter and pick the appropriate Greek letter from a palette. You then mark the margins, this is to aide in selecting which piece goes with which. Eventually you land on a screen where you can try to fit fragments together.
Like I said -- an amateur science geek's paradise. So, if you like that kind of stuff be sure to head over there and check out their projects.
