I am looking for examples: show me some real computational power in seven or fewer lines of Julia that read clearly. It is ok to be using other packages, though no more than four (and it is ok to use fewer). Each example is intended to make a compelling case for Julia to skilled practitioners of w…

Thanks. As a curiosity, plotting the normal around that new strip seems to indicate that it is orientable? [Makie_band_is_orientable]

Would you mind sharing the code for that normal vector? The orientability depends on the parity of the number of twists.

That depends on how many times the band is twisted before it is glued back together.

Depends whether it is an even or an odd number of turns :slight_smile:, factor 3s corresponds to 6 turns which is even, here is s/2 one turn lower = [Point3f0(.2cos(s/2),0.0, 0.0) .+ (1 + 0.2sin(s/2))*Point3f0(0, cos(s), sin(s)) for s in t] upper = [Point3f0(-.2cos(s/2),0.0, 0.0) .+ (1 - 0.2sin(s/2…

@dpsanders , the code is the same as in the Mobius strip further above (using the partial derivatives and cross product). Just changed M(u,v) consistently with @mschauer ’s strip definition: M(u,v) = (v/2*cos(3u), (r + v/2*sin(3u))*cos(u), (r + v/2*sin(3u))*sin(u)) # other strip by @mschauer

Very nice, I hope you’ll forgive me stealing this in a math.stackexchange comment at real analysis - For what values does the geothmetic meandian converge? - Mathematics Stack Exchange :slight_smile:

For a fairer comparison: Python has mean, median, and geometric_mean functions that could be employed like the Julia library functions. There’s no arbitrary recursion depth here.

Thanks. It was a snip from the 1st comment I saw on Twitter. Language syntax comparison suffer from the same type of problem as language performance comparison: it depends on the ability of the person writing the code & on the actual language The world would be better off if there was a “languag…
