Who Should Make the Coffee?

A man and his wife were having an argument about who should brew the coffee each morning. The wife said, "You should do it, because you get up first, and then we don't have to wait as long to get our coffee."The husband said, "You are in charge of the cooking around here so you should do it, because that is your job, and I can just wait for my coffee."Wife replies, "No, you should do it, and besides it says in the Bible that the man should do the coffee."Husband replies, "I can't believe that! Show me."So she fetched the Bible, and opened the New Testament and showed him at the top of several pages, that it indeed says, "HEBREWS."

Gottlieb Haberlandt

Died 30 Jan 1945 at age 90 (born 28 Nov 1854).Austrian botanist, pioneer in the development of physiological plant anatomy, and the first person to study plant tissue culture (1921). In Physiologische Pflanzenanatomie (1884; "Physiological Plant Anatomy") he distinguished 12 tissue systems based on function (mechanical, absorptive, photosynthetic, etc.) Although his system was not accepted by other botanists, the analysis of the relations between structure and environment has been useful in the study of plant adaptations to different habitats. In 1902, he released the hypothesis of "totipotency" - that even the smallest unit of a cell is capable of forming a complete plant in the future. In 1913, Haberlandt discovered that a compound found in phloem had the ability to stimulate cell division.
