The Astronomer Specialized Cleaning System.

Our bathroom has a specialized showering system, where the astronomer stands inside a tiny 60x60 cm2 white tub. Half of it is enclosed by 2 cold fixed walls, the other half is delimited by cold flexible colored cloth. Cloth flexibility allows the transit of the astronomer to the interior of the showering chamber. Water temperature is adjusted via a two-knob interface, and is highly susceptible the the astronomer's dexterity in temperature-combination of water. The left know controls the amount of really HOT water, and the left one adjusts the flow of freezing cold water.
The Zen balance between the rotation of both knobs thus yields a pleasant water temperature. Water too hot, burns; water too warm, creates convection air currents that affect the position on the cold wet flexible cloth surrounding the chamber and reducing its usable volume.
On the other hand, water too cold is not preferable to getting stuck on the wet cloth!

The astronomer's bath is thus a daily challenge for which patience and balance should be mastered.
