Grandmother....Is that you?

A woman goes to the local psychic in hopes of contacting her dearly departed grandmother. The psychic's eyelids begin fluttering, her voice begins warbling, her hands float up above the table, and she begins moaning. Eventually, a coherent voice emanates, saying, "Granddaughter? Are you there?"

The customer, wide-eyed and on the edge of her seat, responds, "Grandmother? Is that you?"

"Yes granddaughter, it's me."

"It's really, really you, grandmother?", the woman repeats.

"Yes, it's really me, granddaughter."

The woman looks puzzled, "You're sure it's you, grandmother?"

"Yes, granddaughter, I'm sure it's me."

The woman pauses a moment, "Grandmother, I have just one question for you."

"Anything, my child."

"Grandmother, when did you learn to speak English?"

Johannes Diederik van der Waals

Born 23 Nov 1837; died 9 Mar 1923 at age 85.Dutch physicist who was awarded the 1910 Nobel Prize for Physics for his research on the gaseous and liquid states of matter. He was largely self-taught in science and he originally worked as a school teacher. His main work was to develop an equation (the van der Waals equation) that—unlike the laws of Charles Boyle and Jacques Charles—applied to real gases. Since the molecules do have attractive forces and volume (however small), van der Waals introduced into the theory two further constants to take these properties into account. The weak electrostatic attractive forces between molecules and between atoms are called van der Waals forces in his honour. His valuable results enabled James Dewar and Heike Kamerlingh-Onnes to work out methods of liquefying the permanent gases.[Note: Alphabetizing under rules for Dutch names, usage is "Waals, Johannes van der". Notice use of lower case for "van der". Contrast German names like "Von Braun, Werner".]
