For 2000 years, Euclid’s Elements has been the standard of perfection for human reasoning. The field of mathematics has developed emulating this standard. No other art or science has offered the human mind this quality of reasoning.
Thus, mathematics is the backbone of the sciences, technology and engineering. Like a strong frame, proper mathematical training, such as based on Euclid, offers the human mind an ability to think clearly, consistently and with certainty. These are valuable qualities for any walk of life.
