− | + | In this comic, [[Megan]] mentions to [[Cueball]] that their company spends a lot on chemicals for which you can find formulas online. She suggests assembling chemicals from atoms "bought in bulk," holding a sheet of paper with the {{w|empirical formula}} C<sub>6</sub>H<sub>5</sub>NO<sub>2</sub>, which designates [https://pubchem.ncbi.nlm.nih.gov/#query=C6H5NO2 hundreds of compounds] including {{w|nitrobenzene}}, {{w|niacin}}, {{w|isonicotinic acid}}, and {{w|picolinic acid}}, followed by their component elements listed with prices. The ambiguity of chemical formulae is one of the jokes in the comic. | |
− | " | + | While many expensive chemicals are composed of inexpensive and easily available elements, "assembling" those elements into specific molecules is rarely as simple as Megan implies, although it's conceivable that this could change as nanotechnology and artificial intelligence develop. That work is the primary purpose of the global chemical industry. In-house {{w|chemical synthesis}} is usually not cost effective, because end users have limited time and are generally unable to leverage the {{w|economies of scale}} inherent in bulk manufacturing by specialist industrial firms.[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880393/] However, we don't know whether Megan and Cueball work in a laboratory, factory, or some other industrial setting. If they need chemicals in bulk, or only very small quantities, synthesizing them might be cost effective. In any case, producing chemicals from their constituent elements or {{w|Precursor (chemistry)|precursor compound}}s is difficult and time-consuming, usually requires expensive equipment, and is often fraught with peril.[https://www.youtube.com/watch?v=5QwW2owNWgc] {{w|Nitrobenzene}}, one of the C<sub>6</sub>H<sub>5</sub>NO<sub>2</sub> compounds, is an excellent example because it is explosive and extremely toxic, and its synthesis is highly exothermic, making it one of the most dangerous syntheses in the chemical industry.[https://www.icheme.org/media/10339/xiii-paper-36.pdf] Such issues answer Cueball's question as to why more places don't manufacture their own compounds from atoms. Usually chemicals are derived from precursor chemicals instead of constituent elements. Megan seems to be imagining synthesis as a much simpler process without reactivity, energy release, or hazardous intermediate substances. The characters' naivety also gives rise to the humor of the comic. |

− | The title text refers to the fact that older people often complain that "kids these days" don't know how to do things that seemed fundamental to past generations. Randall may have expressed that he dislikes other statements like these in [[2165: Millennials|previous comics]]. It may also refer to the decline of home {{w|chemistry set}}s popular from the late 1700s through the early 1980s that encouraged kids to experiment with basic chemical reactions like generating esters or polymers, or the even older decline in home manufacture of gunpowder as was common in the 1800s. Chemical engineering was more widely practiced during the development of plastics, but far fewer people understand how they are made today. Similarly with automobiles, domesticated crops, and many other technologies that progressed through a period of popular attention but became siloed into industries, corporations, governments, or branches of academia.

Big Oil and Big Pharma are real industrial nicknames; with "Big Pharma", huge corporations invest in research and then charge immensely high prices for medicines. This became more notable when the coronavirus vaccine was released, with media and commerce being focused on large pharmaceutical manufacturers rather than community labs, where community labs could possibly have distributed vaccines directly to their surrounding communities, and recruited from these communities to aid manufacturing, if supported by their governments and economies. Comparatively, "Big Molecule" is fictitious. |

+ | Megan is holding a note that shows how many of the four type of atoms she needs to build one of those she wish to assemble. It seems like the paper lists prices for buying 6 carbon, 5 hydrogen, 1 nitrogen and 2 oxygen atoms. Although the (very small?) prices cannot be read. But the numbers are for certain from the formulae, so the $ sign must refer to the unreadable bit coming after. Also she sums the number of atoms up, to find that she only needs 14, but still with an unreadable price sum to the right of the number of atoms. She thus suggest buying atoms in bulk, which should be even cheaper than buying them individually. However, this is another layer of humor, as you can neither buy individual atoms or get a price for them. Just showing her complete lack of understanding of chemistry. | ||
