Predicate Logic and Popular Culture (Part 53): Ylvis

Let G(x,y) be the proposition “x goes y.” Translate the logical statement

G(\hbox{dog},\hbox{woof}) \land G(\hbox{cat},\hbox{meow}) \land G(\hbox{bird}, \hbox{tweet}) \land G(\hbox{mouse}, \hbox{squeak})

\land G(\hbox{cow},\hbox{moo}) \land G(\hbox{frog}, \hbox{croak}) \land G(\hbox{elephant}, \hbox{toot})

\land G(\hbox{duck},\hbox{quack}) \land G(\hbox{fish},\hbox{blub}) \land G(\hbox{seal}, \hbox{ow ow ow})

With the slight exception of one line (“Ducks say quack”), this is the opening verse of perhaps the most head-scratching hit song in modern memory.

Context: This semester, I taught discrete mathematics for the first time. Part of the discrete mathematics course includes an introduction to predicate and propositional logic for our math majors. As you can probably guess from their names, students tend to think these concepts are dry and uninteresting even though they’re very important for their development as math majors.

In an effort to making these topics more appealing, I spent a few days mining the depths of popular culture in a (likely futile) attempt to make these ideas more interesting to my students. In this series, I’d like to share what I found. Naturally, the sources that I found have varying levels of complexity, which is appropriate for students who are first learning prepositional and predicate logic.

When I actually presented these in class, I either presented the logical statement and had my class guess the statement in actual English, or I gave my students the famous quote and them translate it into predicate logic. However, for the purposes of this series, I’ll just present the statement in predicate logic first.

Predicate Logic and Popular Culture (Part 52): Peabo Bryson

Let A(t) be the proposition “You are in my arms at time t,” and let H(x) be the proposition “I hold you at time t.” Translate the logical statement

(\exists t_1<0(A(t_1)) \land ( (\exists t_2>0 A(t_2)) \Rightarrow (\forall t \ge t_2(H(t))),

where the domain is all times and time 0 is now.

The straightforward way of translating this into English is, “There was a time in the past that you were in my arms, and if there exists a time that you are in my arms in the future, then I will hold you for all times after that.” More poetically, this is one of the lines of one of the great R&B love songs of the 1980s.

Predicate Logic and Popular Culture (Part 51): Tears for Fears

Let L(x,t) be the proposition “x lasts until time t,” and let W(x) be the proposition “x wants to rule to world.” Translate the logical statement

\lnot (\exists x \forall t (L(x,t))) \land \forall x(W(x)),

where the domain is all people.

The straightforward way of translating this into English is, “It is false that there exists something that lasts for all time, and everybody wants to rule the world.” This matches the close of the second chorus of the 1980s hit song by Tears for Fears.

More recently, this song was covered by Lorde for the soundtrack of one of the Hunger Games movies.

Predicate Logic and Popular Culture (Part 50): Brad Paisley

Let S(x,y) be the proposition “x sees y, and let T(x,y) be the proposition “x thinks y.” Translate the logical statement

(S(\hbox{you}, \hbox{deer}) \Rightarrow S(\hbox{you}, \hbox{Bambi}))

\land (S( \hbox{I}, \hbox{deer} ) \Rightarrow S( \hbox{I}, \hbox{antlers up on the wall}))

(S(\hbox{you}, \hbox{lake}) \Rightarrow T(\hbox{you}, \hbox{picnic}))

\land (S( \hbox{I}, \hbox{lake} ) \Rightarrow S( \hbox{I}, \hbox{a large mouth up under that log}))

This almost perfectly matches the opening two lines of Brad Paisley’s “I’m Still A Guy.”

And I can’t resist also showing a clip of Tim Tebow singing along to the chorus when Brad Paisley had a concert in Denver and Tebowmania was at an all-time high.

Predicate Logic and Popular Culture (Part 49): Chris Janson

 

Let M(x) be the proposition “Money can buy me x.” Translate the logical statement

\lnot(\forall x (M(x))) \land M(\hbox{a boat}).

The straightforward way of translating this into English is, “It is false that money can buy me everything, and money can buy me a boat.” These are the closing lines of the chorus of the title song of Chris Janson’s debut country album.

Predicate Logic and Popular Culture (Part 48): Jana Kramer

Let K(x,t) be the proposition “He kisses x at time t.” Translate the logical statement

\exists t_1 <0 (K(\hbox{I}, t_1) \land \forall t < t_1 \forall x( \lnot K(x,t)))

\land \exists t_2 <0 (K(\hbox{she}, t_2) \land \forall t > t_2 \forall x( \lnot K(x,t))) ,

where time 0 is now.

The straightforward way of translating this into English is, “There was a time in the past that he kissed me, and no one kissed him before then; and there will be a time in the future that he’ll kiss her, and no one will kiss him after that.” More succinctly, this is the first line of the chorus of one of country music’s biggest hits from 2015.

Predicate Logic and Popular Culture (Part 47): Zac Brown Band

Let F(x) be the proposition “x is a good friend,” let S(x) be the proposition “x lives down the street,” let G(w) be the proposition “w is a good-looking woman,” let A(w) be the proposition “w has her arms around me,” let p be the proposition “I am in a small town where it feels like home,” let N(x) be the proposition “I have x,” and let H(x) be the proposition “I need x.” Translate the logical statement

\exists x_1 \exists x_2(F(x_1) \land F(x_2) \land S(x_1) \land S(x_2) \land x_1 \ne x_2)

\land \exists w(G(w) \land A(w)) \land p \land \forall x (N(x) \Leftrightarrow H(x)).

I think this is a reasonable translation of the chorus of one of country music’s big hits from 2015.

The straightforward way of translating this into English is, “There exists a time in the future that I will live in a big old city for all times after that time, and you will be always be mean.” More lyrically, this is part of the chorus of one of Taylor Swift’s biggest hits.

C(\hbox{Rick}) \land S(\hbox{Rick}, \hbox{I}) \land \forall x (C(x) \land x \ne \hbox{Rick} \Rightarrow \lnot S(x,\hbox{I}),

The straightforward way of translating this into English is, “Rick is in Casablanca and has less scruples than I, and everyone else in Casablanca who isn’t Rick doesn’t have less scruples than I.” Naturally, this is one of the great lines of the movie Casablanca:

Ricky, I’m going to miss you. Apparently you’re the only one in Casablanca with less scruples than I.
