This comic is a classic example of taking an absurd premise, and applying correct science to it, to see how different the conclusion is to the real world.

Chemical bonding is a well-known subject which explains the formation of {{w|molecule}}s from {{w|atom}}s. This comic refers to three {{w|chemical element}}s: Carbon (C), Hydrogen (H), and Oxygen (O). In real chemistry, the formation of bonds between atoms depends on the number of valence electrons each atom has, and how accessible those electrons are for bonding. The comic jokingly replaces valence electron theory with a theory that the number of bonds an atom can form depends on the number of {{w|Leaf vertex|leaf vertices}} possessed by the chemical symbol's letter. A leaf vertex is a vertex having only one edge connecting to one other vertex. "H" for example, the chemical symbol of Hydrogen, has 4 leaf vertices. This is shown in the comic by the four half-circles placed at each leaf vertex of the "H". Thus, in the comic's theory, elemental hydrogen can form 4 bonds. Oxygen, however, having the chemical symbol "O", has no leaf vertices, and according to the comic's theory should not bond to anything, and is therefore inert.
  
The idea of Typographic Chemistry presented in this comic is a play on  Douglas [[Hofstadter]]’s {{w|Typographical Number Theory}} and [http://smallshire.org.uk/sufficientlysmall/2013/05/12/typogenetics-in-f-part-i/ Typographical Genetics], which are featured in {{w|Gödel, Escher, Bach}}. While Hofstadter's typographical systems are designed to model aspects of real genetics and number theory, Randall abuses this notion by inventing a typographical system which bears no resemblance to real chemistry.

Of course, the theory is completely inconsistent with observed chemistry. While the comic declares oxygen is inert and forms no bonds, this is not really the case: the two unpaired valence electrons in a lone oxygen atom makes oxygen reactive, and oxygen readily form molecules. Diatomic oxygen, O<sub>2</sub>, makes up about 20.9% of Earth's atmosphere, and is essential for aerobic life, including human life. Similarly, a water molecule consists of an oxygen atom tightly bonded to two hydrogen atoms.

By observing real chemical compounds, chemists have deduced that hydrogen atoms really have 1 valence electron, carbon 4 and oxygen 6, allowing Hydrogen to have up to 1 bond, carbon up to 4, and oxygen up to 2. Thus it is Carbon which can have up to four bonds, and really is {{w|graphite|often found}} in {{w|diamond|crystalline form}} in nature (e.g., diamonds, coal); Oxygen which can have up to 2 bonds, and can combine with Carbon to form CO2 (instead of C2H in the comic). We can see here that Randall is giving "typographic" Hydrogen real-life Carbon qualities, since "typographic" hydrogen can have 4 bonds, just like real-life carbon. The same goes for giving "typographic" Carbon real-life oxygen qualities, etc. "Typographic" oxygen simply takes on the properties of the real-life noble gases in the comic (Helium, etc.), which form no bonds and are inert, just like "typographic" Oxygen is in the comic.
  
Of course, the theory is completely inconsistent with observed chemistry. While the comic declares oxygen is inert and forms no bonds, this is not really the case: the two unpaired valence electrons in a lone oxygen atom make oxygen reactive, and oxygen atoms readily form molecules. Diatomic oxygen, O<sub>2</sub>, makes up about 20.9% of Earth's atmosphere, and is essential for aerobic life, including human life. Similarly, a water molecule consists of an oxygen atom tightly bonded to two hydrogen atoms.

While the compound "ethynyl radical" with structure C-C-H has the formula C2H, there is no molecule with the C-H-C structure in nature. The word "mydrane" is a whimsical neologism for this fictional substance: the "hydr-" prefix for hydrogen is changed to "mydr-" (the "my" component is not found in organic chemistry) combined to the "-ane" suffix for alkanes (simple H-C structures).

Thus carbon can have up to four bonds, and really is {{w|graphite|often found}} in {{w|diamond|crystalline form}} in nature (diamonds and coal are {{w|allotropy|allotropes}} of carbon); oxygen can have up to 2 bonds, and can combine with carbon to form CO<sub>2</sub> (instead of C<sub>2</sub>H in the comic). [[Randall]] thus gives to "typographic" hydrogen qualities that belong in real-life to carbon, since "typographic" hydrogen can have 4 bonds. Similarly, "typographic" carbon is ascribed properties belonging to real-life oxygen. "Typographic" oxygen takes on the properties of the real-life noble gases (like helium, neon, and argon), which form no bonds and are inert.

The title text points out that the theory as presented only applies to sans-serif text. A {{w|serif}} is a small line across the end of each stroke. "H", for instance, would have four serifs, each with two leaf vertices. Thus hydrogen in a serif font would be able to form 8 bonds making it, according to the comic's theory, "more reactive". This would be the case with real atoms that have less than four valence electrons, as they would have more space for bonds to other atoms.
  
While the {{w|ethynyl radical}}, which has the structure ∙C≡C–H, does have the formula C<sub>2</sub>H, there is no molecule with the C–H–C structure in nature. The word "mydrane" is a whimsical neologism for this fictional substance: the "hydr-" prefix for hydrogen is changed to "mydr-" (a prefix which does not exist) and combined to the "-ane" suffix for {{w|alkane}}s (simple hydrocarbon molecules). Perhaps Randall named this compound "mydrane" to declare ownership of it ("my-" as in "mine"). Another reasonable assumption is that the word is a portmanteau of methyl (Me- is the prefix for 1 carbon chains attached to a functional group) and hydrogen with the -ane suffix for alkanes; the nomenclature stems from (di-)m(ethyl) (h)ydr(ogen) -ane, which would form mydrane. Technically, the nomenclature would be "dimethyl" since there are two "methyl" groups attached to the functional group (i.e. hydrogen in this case). It would, however, not be uncommon to drop a di- from a compound name if it's redundant (only one possible compound, e.g. dimethyl ether which sometimes is referred to as methyl ether) or makes a clumsy name ("dimydrane" could make it sound as if there are two mydrane groups).
