115B . Zhang Yitang 5 Years Ago

Technology dumb, had him for online class, and his lectures were horrendous because he simply did not know how to work the online classes. Additionally, he will intentionally ignore your emails, if he does not understand questions you ask him. Grades harshly, and very not helpful with anything.

After nearly a year, I came to check in again, hoping that Siegel can complete the zero point as soon as possible. .

MATH115A . Zhang Yitang 2 Years Ago

Professor is very intelligent so sometimes he goes faster than he realizes so that can make him hard to follow. exams and hw are very rigorous but he offers help in lecture so go to lecture!! overall fair course but study your class notes because homework and exams are a much trickier version of the notes. overall amazing professor! kind & caring

108A . Zhang Yitang 2 Years Ago

I visited this website a few years ago, and I also read Teacher Zhang's documentary and sister's article, and I read it again today. After a years-long hiatus, Zhang published his Landau-Siegel Zeros paper today. Hope he succeeds again and becomes a legendary mathematician! Blessings from Shaoxing, China. Quoting Du Fu's poem again...
