How were complex analysis methods, like the Joukowsky transform, used in early aircraft design?
The Joukowsky transform is a conformal mapping of a disk to an airfoil shape.
The wiki page says that "it was historically used to understand some principles of airfoil design".
That's kind ...

Before metric length units were based on the speed of light, how were sub-units accurately derived from the reference bars?
Its my understanding that before metric units of length were based on the speed of light, there were reference bars that were used to calibrate other (mostly calibration) equipment.
How were these ...

Math-education comparsion between Japan and United States from perspectives of engineering contributions
I may think that this post is unsuitable in HSM.
NASA launches rockets far more than JAXA(Japan Aerospace Exploration Agency).
BostonDynamics-robots are way general-purpose than Japan's FANUC-robots.

Origin of the notation $s = \sigma + j\omega$ in electrical engineering/control theory
In analytic number theory it is traditional to write a complex variable as $s = \sigma + it$, with the letter $t$ going back to Riemann's paper on the zeta-function (1859) and the letter $\sigma$ ...

What is the origin in the discrepancy between engineers' and physicists' notation of waves?
my question is very simple. Physicists use this notation in order to write a (for example) plane wave:
$$
\xi(z) = \xi^+ \mathrm{e}^{+\mathrm{i}kz} + \xi^- \mathrm{e}^{-\mathrm{i}kz},
$$
where $\xi^+$ ...
