I am no guru, but when .guru domains became available, my colleagues suggested that only I could own that domain. We bought supermemo.guru in February 2014, and I accepted the position of the guru on the understanding that the world of SuperMemo is so specialist that it may indeed be hard to find a better SuperMemo Guru.
This wiki represents my personal point of view, my hypotheses, my models, my philosophy. It often does not reflect the official positions of SuperMemo World. At times, it may even go against "scientific consensus". If you learn something of value, check my references, and if you do not find any, consult other sources, or write to me.
Starting on Feb 7, 2017, with my late mom's 96th birthday, I will incrementally work on my new project and my new hobby: Problem of Schooling.
