Quote of the week

"Homeworks are to research like sitcoms are to life. In sitcoms, you basically know everything's going to work out and by the end of the episode you get resolution."

The power of spectral techniques

It is quite amazing to think that we can solve \(Lx=b\) even faster than sorting the edges...

Puzzle

A puzzle given by an office-mate:
There is a polynomial \(p(x) = a_0 + a_1x + a_2x^2 + \dots+a_nx^n\) where \(a_0, a_1, \dots, a_n \in \mathbb{Z}^+\). Knowing only \(n\), you may query the value of \(p(x)\) for any \(x\). The goal is to recover the coefficients with minimal queries.

Cosmos: A Spacetime Odyssey

傳說中在 imdb 得到很高排名, 最特別的它是紀錄片! (紀錄片在 imdb 也可以 9+ 分一定不簡單)

很大程度上歸功於取代了一般紀錄片的 "某專家坐在 office 俾 speech 的場面" 而是用 CGI/片作為背景

P.S. host 坐的那 spaceship 非常似 Tardis, 而且經常出現 "travel through time and space", 很難不聯想起 Doctor Who 啊
