André-Louis Danjon

Born 6 Apr 1890; died 21 Apr 1967 at age 77.French astronomer who devised a now standard five-point scale for rating the darkness and colour of a total lunar eclipse, which is known as the Danjon Luminosity Scale. He studied Earth's rotation, and developed astronomical instruments, including a photometer to measure Earthshine - the brightness of a dark moon due to light reflected from Earth. It consisted of a telescope in which a prism split the Moon's image into two identical side-by-side images. By adjusting a diaphragm to dim one of the images until the sunlit portion had the same apparent brightness as the earthlit portion on the unadjusted image, he could quantify the diaphragm adjustment, and thus had a real measurement for the brightness of Earthshine.«

Try this...
On your way home from work, stop at a pharmacy and purchase a rectal thermometer made by Johnson & Johnson. Be very sure to get this brand.
When you get home, lock your doors, close the blinds and take the phone off the hook so you will not be disturbed. Change into very comfortable clothing and sit in your favorite chair.
Open the package and remove the thermometer. Now, carefully place it on a table or a surface so that it will not become chipped or broken. Take out the literature and read it carefully. You will notice that in small print there is a statement....
"Every Rectal Thermometer made by Johnson & Johnson is personally tested."
