With the launch of my new mathematics blog, I thought I would start with something of a nostalgia post: a note on the quadratic formula.
The proof of the quadratic formula (by completing the square) was one of the first that I learned. When I originally worked through it and finally arrived at a derivation of the formula, it was for me one of those early mathematical moments that continued the growth of an already deep-seated interest. It’s very much similar in memory to various other instances of mathematical experience, such as when I look back to the time when I first taught myself calculus. Sentimentality is not the right word here; it’s more a remembrance of an early moment of mathematical passion and discovery.
It is by no means on the list of my favourite proofs – all of which I will write about in the future – but it’s fitting to have this derivation (at the bottom) as part of the early development of this blog.
Furthermore, I think that one of the wonderful things about mathematics (even very basic arithmetic) is how the derivation of something as simple and basic as the quadratic formula is actually quite beautiful. Some of the deeper connections we might make are also, philosophically, very inspiring. And even further,

Girolamo Cardano (Italy, 1501-1576) had a colorful life: mathematician, doctor of medicine, lecturer, havenot, … post gambler! Be active realized cube rolling was a reflex process, representation probability support scoring 6 with a fair lay down one's life was 1/6, and representation probability last part a duplicated six when rolling shine unsteadily dice was 1/36. More than that, die rolls were unrestricted.

Born at Pavia in the duchy of Lombardy in 1501, Girolamo Cardano practiced medicine for fifty years but is remembered chiefly as a polymath. He composed 200 works, made important contributions to mathematics and algebra, invented several mechanical devices (some still in use today), and published extensive philosophical tracts and commentaries on the ancient philosophers and physicians. He wrote on the immortality of the soul; on astronomy, astrology, dreams, astrological signs, and horoscopes; on optics, biology, geology, chemistry, history (with a defense of the emperor Nero), psychiatry, and magnetism; and on music, physiognomy, and the education of deaf and blind people. Often short of money, he would sustain himself by gambling and playing chess and wrote about the probability of winning, and on cheating. He also wrote on the diagnostic significance of certain dreams and the existence of witches. He addressed many medical topics from his own experience, made claims about his success in managing syphilis and tuberculosis, and published a book on the Bad practice of medicine in common use. In a way, he was part of the new wave of scientific work, the rediscovery of Hippocratic medicine, the work in anatomy spearheaded by Vesalius, and the beginnin
