scientific mind

The other day, while my husband was writing a program of a game, he needed the readings of points on the circle and asked me if I still remember how to calculate it.
I had no idea at that moment. It made me recalling the time when I was learning such kind of thing in high school. That was a horrible period of time, while we had a new teacher as a replacement, when my favorite teacher went to the hospital for curing his liver disease. It was also from them, I learned that the two parts of a married couple could be sooooooooooooooo different.
Anyway, the horrible memory about the past cannot help us solving problems. So, I checked the theory online and found the solution with some brooding.
Nothing is impossible, if one is with a calm enough mind. My husband felt the same happiness as I felt.
