Short Summary
Main recommendation: The video's central takeaway is that, by citation count, the most influential scientific papers are overwhelmingly lab methods rather than famous discoveries, so citation-based rankings reveal how science is built step by step. Simon Clark read about the top 100 most-cited papers from a 2014 Nature list (he discusses them, not that he read all 100 in full depth), finding biology dominates and that the top six all describe biology lab techniques with 50,000 to 300,000 citations each. He argues citation counts measure usefulness of techniques, not the importance of ideas, so the list is a biased but revealing window into how science is done.
Key Points
- Citation count is the measure used: a paper needed over 12,000 citations (as of 2014) to enter the top 100, while most published papers have 0 to 9.
- Biology dominates the list: about 39 papers described lab techniques, and over 50% related to the study of living beings.
- The top six papers, all biology techniques, include Lowry's protein assay (the top paper), SDS-PAGE improvement, the Bradford protein assay, Sanger DNA sequencing, RNA isolation, and the Western blot.
- Big discoveries are largely absent: DNA's structure, chaos theory, special relativity, and the Schrödinger equation do not appear, because widely used methods get cited far more than landmark ideas.
- Single-author papers appear more often than expected, and their frequency declined over time, as he predicted/expected, and later entries shift from lab techniques toward computer-based methods and software.
Details Worth Noting
- Concrete instructions: No step-by-step instructions were given; the video is a reflection on the list rather than a how-to, so no actionable procedures are offered.
- Fred Sanger is one of only four people to win two Nobel Prizes, one for DNA sequencing and one for protein sequencing (fun fact mentioned in passing).
- "Fuzzy sets" was the highest-ranked maths paper and the best-titled entry; the shortest paper (Feinberg and Vogelstein) is a one-page addendum improving a method for tracking DNA-interacting enzymes.
- The graphene paper and carbon nanotube paper were the top-ranked physics entries, likely because materials science draws heavily on them.
- Two oddities: a paper on determining whether a patient is left- or right-handed (61st) and Jorgensen et al.'s water simulation paper (79th), which the speaker could not explain.
Bottom Line
Citation rankings favor reusable tools over breakthrough ideas, so the top 100 mostly shows how incremental lab methods, especially in biology, quietly hold science together.
