<Iskierka> does it only work assuming you fold on a dip

<raptop> well, if you have a bunch of compute, you can fold across a very large dataset. Compare with using RVs in the lomb-scargle method (where you search ~all periods in a range)
<raptop> But how did they get spacially resolved images of a star?

* Iskierka does not understand the methods of exoplanet hunting enough to understand the issue then
<raptop> fair enough
<raptop> Complete list of stars that have disks (so this method can be used) when observed with a normal telescope: Sol
<raptop> Interferometry can do cool stuff, but I'm not sure if this would work (and then most interferometers have rather strict magnitude limits)

<egg|anbo|egg> !choose sleep|cube root
<galois> egg|anbo|egg: Your options: sleep, cube root. My choice: cube root
<egg|anbo|egg> hm
<Iskierka> is a fast inverse cube root possible the same way as for a square root
<egg|anbo|egg> the classical fast inverse square root is not a thing you should do anymore fwiw
<egg|anbo|egg> but integer arithmetic tricks are reasonably classic to get a first guess on the cube root though

<Iskierka> only in that your software implementation will never beat the fact everything currently has a hardware implementation of it now
