What is BOINC?? In so many words BOINC lets you help cutting-edge science research using your computer (Windows, Mac, Linux) or Android device. BOINC downloads scientific computing jobs to your computer and runs them invisibly in the background. It’s easy and safe.
The BOINC project is located at the University of California, Berkeley. It has existed since 2002, with funding primarily from the National Science Foundation.
About 30 science projects use BOINC; examples include Einstein@Home, IBM World Community Grid, and SETI@home.These projects investigate diseases, study global warming, discover pulsars, and do many other types of scientific research.
I personally run BOINC on my Android tablet, which you can download here; and here is a list of projects you can contribute to.
