Forgive the recent apparent obsession (I’d call it a fascination) with the #cycloid but I’ve just discovered something I’d not heard of before. It is also called a #TautochroneCurve or #Isochrone curve, which means that a particle starting from any location on the curve will get to the #MinimumPoint at precisely the same time as a particle starting at any other point.

Imagine a circular wheel rolling, without skidding, on a flat, horizontal surface. The #locus of any given point on its #circumference is called a #cycloid. It is a #periodic #curve with #period over the #circle's circumference and has #cusps whenever the point is in contact with the surface (the two sides of the curve are tangentially vertical at that point).

I’m Laura. I’m an #ESA-#AURA astronomer at @spacetelescope.

I’m one of two deputy heads of the #ScienceMissionOffice, where I work on #SciencePolicies for our observatories and on science infrastructure for our staff.

For research, I study the #Kinematics and #Dynamics of small stellar systems using #ProperMotions from #HST, #Gaia, and soon #JWST. I have a particular fondness for #GlobularClusters but also study #DwarfGalaxies and #SatelliteSystems of larger hosts.
