[Sca-cooks] Fwd: A.Word.A.Day--albedo

[Johnna Holloway]

I looked this up and albedo is not that common a word, nor is it very old.
OED does mention this meaning for albedo* *
A white structure, tissue, or material (Webster 1934); spec. the white 
pith of the inner peel of citrus fruits.*
*The first quote is 1949 J. B. S. Braverman /Citrus Products/ iii. 77 
Penetrating further into the peel of citrus fruit, one comes to the 
white, spongy, parenchymatous layer (mesocarp), generally known as the 
albedo.
As for it meaning whiteness as in astronomy, that only dates to 1859.

By the way, Pith meaning core goes back to the 800's.
