1/ When you say "Drive a block, take a right," you're giving curvature k as a function of arc length s. In 1990, curves for which k is a polynomial in s were termed "polynomial spirals." They've since been applied to self-driving cars. Great topic for #calculus 3! #MTBoSpic.twitter.com/XEaoZejNd0

4/ History and applications:
@raphlinus Has written a history of the Euler spiral: https://www2.eecs.berkeley.edu/Pubs/TechRpts/2008/EECS-2008-111.pdf … A quick overview of applications of the Euler spiral is on Wikipedia: https://en.wikipedia.org/wiki/Euler_spiral …Prikaži ovu nit -
5/ Mathematics: The more general polynomial spirals are investigated in this 1990 paper by Dillen: https://gdz.sub.uni-goettingen.de/id/PPN266833020_0203?tify= …{%22pages%22:[648],%22view%22:%22info%22}
