Predicate Logic and Popular Culture: Index

I’m doing something that I should have done a long time ago: collecting a series of posts into one single post. The following links comprised my series on using examples from popular culture to illustrate principles of predicate logic. My experiences teaching these ideas to my discrete mathematics students led to my recent publication (John Quintanilla, “Name That Tune: Teaching Predicate Logic with Popular Culture,” MAA Focus, Vol. 36, No. 4, pp. 27-28, August/September 2016).

Unlike other series that I’ve made, this series didn’t have a natural chronological order. So I’ll list these by concept illustrated from popular logic.

Predicate Logic and Popular Culture (Part 92): Annie Get Your Gun

Let W(x,y) measure how well x can do y. Translate the logical statement

\forall y (W(\hbox{you},y) < W(\hbox{I},y)).

This needs no further introduction:

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 91): The Scarlet Pimpernel

Let H(x,t) be the proposition “x happens at time t,” let V(x) be the proposition “x is a valley,” let M(x) be the proposition “x is a mountain,” let S(x,y,t) be the proposition “y must scale x at time t,” let W(x) be the proposition “x are perilous waters,” and let S(x,y,t) be the proposition “y must sail x at time t.” Translate the logical statement

\forall t \exists x (V(x) \land H(x,t)) \land \forall t \exists x(M(x) \land H(x,t) \land \exists y S(x,y,t))

\land \forall t \exists x(W(x) \land H(x,t) \land \exists y S(x,y,t)).

This matches the second half of the opening verse of the showstopper “Into The Fire” from the musical The Scarlet Pimpernel.

I also recommend Steve Amerson’s rendition:

Predicate Logic and Popular Culture (Part 90): The Beatles

Let N(x) be the proposition “You need $latex x.” Translate the logical statement

N(\hbox{love}) \land \forall x (x \ne \hbox{love} \Rightarrow \lnot N(x)).

This matches the title of one of the Beatles’ greatest hits.

Predicate Logic and Popular Culture (Part 89): Into the Woods

Let S(x) be the proposition “x is on your side” and let A(x) be the proposition “x is alone.” Translate the logical statement

(\exists x S(x)) \land (\forall x \lnot A(x)).

Of course, this matches the last two lines of “No One Is Alone,” which was released as a movie in 2014.

I’m personally partial to Steve Amerson’s rendition of this song:

Predicate Logic and Popular Culture (Part 88): Bob Dylan

Let H(x) be the proposition “You have x,” let L(x) be the proposition “You have x to lose,” let $p$ be the proposition “You’re invisible now,” and let S(x) be the proposition “x is a secret to conceal.” Translate the logical statement

((\forall x \lnot H(x)) \Rightarrow (\forall x \lnot L(x))) \land p \land \forall x (S(x) \Rightarrow \lnot H(x)).

This matches the last two lines of the closing verse of this classic from Bob Dylan.

Predicate Logic and Popular Culture (Part 87): Bruce Springsteen

Let R(x) be the proposition “x needs a place to rest,” let H(x) be the proposition “x wants to have a home,” and let A(x) be the proposition “x wants to be alone.” Translate the logical statement

\forall x (R(x) \land H(x) \land \lnot A(x)).

This matches three of the lines in the closing verse of one Bruce Springsteen’s great hits from the 1980s.

Let T(t) be the proposition “t is at night” and let D(t) be the proposition “I could have danced at time t.” Translate the logical statement

\forall t (T(t) \Rightarrow D(t)).

This needs no further introduction:

I also really enjoyed this (she made the finals of Britain’s Got Talent in 2009):
