My mother bought a hula hoop. I believe the last time I twirled it was… em at least 5 years ago or so. But at the moment I can’t stop anymore. It’s fun! And twirling for about 90 seconds isn’t too easy at all if you aren’t in very good physical shape. And I’m not since autumn semester just ended and we have exams and most of time has been conquered by studying. At first I thought in ones and zeros, last few days in logic circuits and some coming days are going to be filled with integrals and such. In the end my paradigm will be ideal gas law.
