good friend I'm an engineer in telecommunications, I graduated from tsu in electronics and I have a post degree in fiber optic and digital transmission, I saw my whole life mathematics as 5 mathematics, and at that time I thought my work and be pure numbers but look never in 25 years of my work have I used the numbers to work, so for that study, sometimes I said that education should change a bit but not bad for worse, the students the teacher gave everything and should not be So, they must investigate expose, that way is that you learn, but life is changing and the human human being too, instead of wanting to get over it, it becomes looser and selfish, it's sad but to education what happens same, instead of demanding more now they demand less
