Bad Pop Rocks

Cassie was taking two of her grandsons on their very first train ride from Dayton, Ohio to Washington, DC.

A vendor came down the corridor selling Pop Rocks, something neither had ever seen before.

Cassie bought each one a bag.

The first one eagerly tore open the bag and popped one into his mouth just as the train went into a tunnel.

When the train emerged from the tunnel, he looked across to his brother and said: "I wouldn't eat that if I were you."

"Why not?" replied the curious brother

"I took one bite and went blind for half a minute."

Born 16 Sep 1736; died 17 Aug 1807 at age 70.German natural philosopher whose empirical approach strongly influenced the work of Immanuel Kant, and later in his life, Tetens became interested in mathematics, especially in actuarial applications. From 1760, as a teacher of natural philosophy he wrote on diverse topics but later began the development of the field of developmental psychology in Germany. He wrote Philosophische Versuche über die menschliche Natur und ihre Entwickelung (1777) on the origin and structure of knowledge. He changed career after 1789 to the civil service during which time he pursued mathematics. As a statistician he produced an Introduction to the Calculation of Life Annuities (1785) and On the Tetens Mortality Curve (1785).«
