==Explanation==

[[Cueball]] is taking a scientific approach to creating a valentine card. Based on the first chart, the recipient is his fiancée since he noted major events (first meeting and engaged, thus they are not married yet, or it should have been noted on the graph). The labels of a heart and smiley represent Cueball's feelings for her and happiness accordingly. This implies that Cueball had love and feelings for someone else before he first met the love he is breaking up with. While they were dating, the feelings and happiness levels were very unstable, as is expected for any new relationship. That later dropped to current levels, probably due to Cueball's lack of love towards her.

In the second panel, there are variables r<sub>0</sub>, r<sub>1</sub>, r<sub>2</sub>, each value at 0.20, -0.61, -0.83 accordingly. Given their names and values between -1 and 1, these are probably {{w|correlation coefficient}}s. Assuming they represent successive periods in time, they appear to show rising happiness (slight positive correlation), then falling happiness (negative correlation), then faster falling happiness (stronger negative correlation). These periods may be those marked on the graph in the preceding frame: first meeting to first date; first date to engagement; engagement to present.

The text in the space between 2nd and 3rd panels show that [[Randall Munroe]] is against {{w|scientific misconduct}}. It also shows that Cueball's rigorous approach makes him realize that the happiness he derives from the relationship is declining, which presents him with a choice. Will he be a true scientist by accepting data that he doesn't like, or will he be romantic and just make a cute card? 

The last panel is a parody of a broken(torn) heart, a common symbol used to represent people falling out of love. The line could be interpreted as a graph of the amount of love between the two or a literal tearing of the heart in two.

He decides that he is a scientist and so presents his significant other with a breakup valentine even though he originally intended it as a confirmation of their love.

The comic may be intended as a cautionary tale to new scientists; while the graph in the leftmost panel shows an apparent correlation between Cueball's love and his happiness, and it shows his happiness is lower than it might be expected to be without his partner, it fails to show that the falling love affects falling happiness-- it may be the case that falling happiness effects falling love, or that both happiness and love are affected by an unidentified factor.  For example, temporary external crises may be weighing on Cueball's relationship as well as his happiness.

The title text seems to be him trying to console himself that he did the right thing. You should not use science to prove that your theory is right, but to find out which theory is the right one!

==Transcript==
:I wanted to make you a science valentine
:with charts and graphs of my feelings for you.
:[A graph shows romance and happiness. Romance cuts off, indicating a breakup before the meeting of Cueball and his current significant other, and happiness dips accordingly.
:A line indicates where the couple first met; romance is jagged thereafter, initially upwards but later down.
:Happiness climbs slightly more steadily and then dips again.
:More lines indicate a period of dating and then one of engagement.]
:and the happiness you've brought me.

:But the more I analyzed
:[Cueball works at a computer.]
:r<sub>0</sub> = 0.20
:r<sub>1</sub> = -0.61
:r<sub>2</sub> = -0.83
:the harder it became to defend my hypothesis.

:In science, you can't publish results you know are wrong
:and you can't withhold them because they're not the ones you wanted.

:So I was left with a question: do I make graphs because they're cute and funny,
:[Cueball sits, looking at a sheet of paper.]
:or am I a ''scientist?''

:Enclosed are my results.
:I hope you can find somebody else
:[A jagged, declining graph is superimposed over a red heart.]
:to be your valentine.
