A knight's tour is a sequence of moves of a knight on a chessboard such that the knight visits every square only once. If the knight ends on a square that is one knight's move from the beginning square (so that it could tour the board again immediately, following the same path), the tour is closed, otherwise it is open. A knight's tour problem is the mathematical problem of finding a knight's tour. Creating a program to find a knight's tour is a common problem given to computer science students. Variations of the knight's tour problem involve chessboards of different sizes than the usual 8 × 8, as well as irregular (non-rectangular) board.
While Brandon was on vacation, he steadily began to master the game theory involving chess. But when he was introduced to the knights tour, he realized this new level of expertise had more involvement than anything he encountered before.

A sabrage is a technique for opening a champagne bottle with a saber, used for ceremonial occasions. The wielder slides the saber along the body of the bottle to break the top of the neck away, leaving the neck of the bottle open and ready to pour. The force of the blunt side of the blade hitting the lip breaks the glass to separate the collar from the neck of the bottle. One does not use the sharp side of the blade. The cork and collar remain together after separating from the neck.
When it comes to using the sabrage technique, it’s not sharpness or size of the blade that matters, but more importantly, it is the strength of the impact.

MNXRLT4U is an acronymous rebus puzzle. It can be solved by its annunciation which, when spoken aloud, should sound like, “Ham and eggs are healthy for you.”
“Before the research on cholesterol provoked such due concern, people believed that “MNXRLT4U.” What was it that the people formally acknowledged?

is a signal processing technique invented in 1901 by Canadian inventor-engineer Reginald Fessenden that creates new frequencies by combining or mixing two frequencies. Heterodyning is used to shift one frequency range into another, new one, and is also involved in the processes of modulation and demodulation. The two frequencies are combined in a nonlinear signal-processing device such as a vacuum tube, transistor, or diode, usually called a mixer. In the most common application, two signals at frequencies f1 and f2 are mixed, creating two new signals, one at the sum f1 + f2 of the two frequencies, and the other at the difference f1 − f2. These new frequencies are called heterodynes. Typically only one of the new frequencies is desired, and the other signal is filtered out of the output of the mixer. Heterodynes are the mathematical dual of the phenomenon of "beats" in acoustics.
A major application of the heterodyne process is in the superheterodyne radio receiver circuit, which is used in virtually all modern radio receivers.

Dear God, please grant me the Serenity to accept the things that I cannot change, the Courage to change the things I can, and the Wisdom to know the difference.
Sometimes when no one else is listening, I recite the serenity prayer to myself and remember that God is always listening.

cigarette soup is the voluntarily unknown consumption of a canned beer or soda that has previously been used as an ashtray or a spittoon for chewing tobacco. This is most likely to occur during keg parties, like minded social gatherings, and occasionally from mischievous pranksters.
While Derek was half dazed from puking in the toilet, he asked Brandon for an opened can of soda to drink. Brandon didn’t realize that he had given Derek a can of cigarette soup, until he yelled, “What the fuck?!”, before vomiting even more than ever.
