I try not to make these “ads” for Scientopia too frequent, but I also want to keep you aware. We at Scientopia founded this site to do what we love, and we all, ALL, do it for free. In fact, we do it for less than free, since many of us have put in a lot of time, and real money, into making sure that Scientopia is real and legit and runs on a day to day basis. So if you’re feeling generous today (or any day!), please do take a look at the right hand side of some of our blogs, where you’ll see a little “donate” button, which links to PayPal, where you can donate a bit and help us keep the lights on. Thanks.
