The propaganda is strong with the three functionaries that this movie did a great job in misleading the public that they were mathematicians. They were number crunchers, mainly. I suppose they were very good at it, but they weren't particularly creative nor did they do any of the heavy lifting involved in the design of the rockets or any of the mathematical theory governing their stability (Johnson was the second author on her most cited paper; the lead author is basically forgotten and ignored, probably because he did the hard theoretical work). The degree to which their contributions have been exaggerated is remarkable. Check out this page, for example, that purports to list the top 10 most "legendary" American mathematicians: https://pantheon.world/profile/occupation/mathematician/country/united-states
Whoever created that page hasn't the slightest clue how to distinguish between self-identified physicists and mathematicians, much less the work Johnson, Jackson, and Vaughn actually did in their careers as NASA number crunchers. And the little blurbs describing them appears to have been written by a borderline illiterate ("She started as a computer at the segregated West Area Computing division in 1951."). Regardless, it's laughable that Katherine Johnson and Mary Jackson appear on any list including John Nash, Claude Shannon, and Norbert Wiener, among others (and why Jackson over Vaughn?). Anyone who knows even a little about physics and mathematics would have to admit this, even the terminally psychotic virtue signalers among them. Just goes to show how effective the propaganda has been.
