Sine curve drawing machine

Paper

During my first years of teaching, I have created very rickety sine curve drawing machine in my father's workshop. Despite its look, it was clearly visible that I have put a lot of time in the project. When I presented my work in the class, I secured myself with telling students: »Don't laugh! If anyone knows how to create better machine, then do it. «
I was very amazed by the students from class 3.a, who had brought the perfect remote control machine the next day. Gloria discipuli, gloria magistri.
Some students shine, when they successfully solve a difficult task. Others, when they are expected to invest hours and hours of work in a complex project. In my case it was neither of this two. Some people only start working when they see a certain task as a challenge. And the challenge usually is to beat a mentor.
That is why, at this point, I would like to ask all the mentors of the world, to sometimes let themselves be beaten by their aspiring students. If you show yourselves as vulnerable from time to time, no one is going to respect you any less because of that. Quite the opposite. You will create around you an ideal space for young talents to flourish and evolve.
