Physics, physical chemistry, and engineering (and most other scientific disciplines) require calculus!
“Baby calculus” won’t do!
If some ethnic groups can’t or won’t learn calculus (or even algebra, geometry etc.), they should just stay out of STEM and stop whining!
Yup. My P-Chem prof insisted that we develop facility in partial differentials around nearly any measurable characteristic followed by re-integration into something that was "useful". At the time, the only way we could derive protein structures was by purifying, crystallizing, then doing X-ray crystallography. We had to work backwards from the X ray data to the protein structure. We also used nuclear magnetic resonance (NMI) to get a sense of how parts of the protein were assembled. Actual sequencing was so primitive that we had to assemble topological sorts of fragments derived from the application of different proteases known to cut specific types of amino acid intersections.
Roll forward to the present time where bioinformatics has merged automated sequencing, databases and specialized search algorithms using tools like BLAST.
