Finito ora. Non è una recensione, che forse scriverò in futuro (dove possa finalmente scrivere più di 500 caratteri 😞)

Devo dire molto simpatico tuttavia: la "sorpresa" romanzata che si sono inventati gli autori, secondo è talmente sopra le righe e tirata per le orecchie, che non regge tanto.
Il setup funziona benissimo, ma poi va via via perdendo. Peccato. Cmq simpatico da leggere, sono contento e lo consiglio.

Évariste Galois was a french mathematician who, as a teenager, solved a 350-year-old problem regarding the condition necessary for a polynomial to be solvable by radicals. His work laid a foundation for a major branch of abstract algebra called Galois theory.

in 1832 Galois wrote to a friend accurately predicting that he would die in a duel taking place the next morning. The duel was likely over a woman. In his final letter, Galois describes his work in mathematics and closed with, "Eventually there will be, I hope, some people who will find it profitable to decipher this mess." He was only 20 years old at his death.

The fascinating Heegner numbers [1] are so named for the amateur mathematician who proved Gauss' conjecture that the numbers {-1, -2, -3, -7, -11, -19, -43, -67,-163} are the only values of -d for which imaginary quadratic fields Q[√-d] are uniquely factorable into factors of the form a + b√-d (for a, b ∈ ℤ) (i.e., the field "splits" [2]). Today it is known that there are only nine Heegner numbers: -1, -2, -3, -7, -11, -19, -43, -67, and -163 [3].

Interestingly, the number 163 turns up in all kinds of surprising places, including the irrational constant e^{π√163} ≈ 262537412640768743.9999999999992500... (≈ 2.6253741264×10^{17}), which is known as the Ramanujan Constant [3].

a fictionalised novel about by , picked up at a . Galois is a remarkably unpleasant protagonist in this - conceited, sexist, and paranoid, among other faults - but the book is still very readable, carried through by vivid depictions of the revolutionary chaos of 1830s Paris.

Obviously it shouldn't be possible to expose (even very wealthy) investors to such potential losses. Parties on the political right always want light touch/self-regulation of financial markets. It only works for hedge funds and investment banks, not for investors.

Aussi, chaque semaine ya qqs offres d'emploi ici : haskellweekly.news/issues/165. mais c'est surtout en ce moment.
