A farmer has three sons. One day, his oldest boy comes to him and pleads with him that he is graduating from school and would really like to get a car. His father says, "Son, come with me." He takes him to the barn and points to the farm tractor and says, "That tractor is needed here on the farm and I promise that as soon as it's paid for, we'll get you a car." The boy was not too happy but he did understand that situation and said, "Okay, Dad."A week later, his second son (10 years old) approaches him wanting a new two-wheel bicycle. Well, he gets the same excuse ... "as soon as that tractor is paid for..."
Shortly, a few days later, son no. 3, his youngest, comes bugging him for a tricycle. Again, 'ol Dad gives him the lecture about the tractor being paid for first.
While leaving the barn, the young boy, more than a little disgusted with the whole thing, sees a rooster mating with one of the hens and promptly goes over and kicks the rooster off the hens back,mumbling to himself the whole time.
His dad says, "Son, why on earth would you do something like that? He didn't do anything to you to deserve that!"
The little boy looks Dad right square in the eye and says,"Hey, nobody rides anything around here until that damn tractor is paid for.

Alexandre-Emile Beguyer de Chancourtois

Died 14 Nov 1886 at age 66 (born 20 Jan 1820).French geologist who was the first to arrange the chemical elements in order of atomic weights (1862). De Chancourtois plotted the atomic weights on the surface of a cylinder with a circumference of 16 units, the approximate atomic weight of oxygen. The resulting helical curve which he called the telluric helix brought closely related elements onto corresponding points above or below one another on the cylinder. Thus, he suggested that "the properties of the elements are the properties of numbers." Although his publication was significant, it was ignored by chemists as it was written in the language of geology, and the editors omitted a crucial explanatory table. It was Dmitry Mendeleyev's table published in 1869 that became most recognized.
