learning curve
David (http://www.italki.com/user/1620170) made a comment on a guy's stay in Irkutsk, Russia (http://www.italki.com/discussion/83107). In his comment he wrote "A tough learning curve for a guy from the tropics!". The first thing that comes to mind is that he had a tough LESSON, having to come back on foot after missing his stop on the bus. But just then my memory rises the idea of memory curve, which is in a shape of some hyperbola, if I am not mistaken, and represents the dependence of memorised material on the amount of time passed after memorising. Could this be the learning curve? Is it a set expression in English?

You are absolutely correct in your thoughts. A memory curve would look like a hyperbola sloping upwards.
