### Mid Semester Final Exam

One night Jack Evans, along with his 3 university friends went out drinkinig till late night, as many college students are prone to do, and didn't study for their test, which, of course, was scheduled for the next day.

In the morning they thought of a plan. They made themselves look as dirty and weird as they could with grease and dirt.

They went up to the dean and explained that they had gone out to a wedding last night and on their return the tire of their car burst. They continued to explain how they had to push the car all the way back and that they were in no condition to appear for the test.

The dean, being a compassionate human being said that they could take the test after 3 days. The students graciously replied that they'd be ready by that time.

On the third day, they appeared before the dean. The dean explained that since this was a special test all four were required to sit in separate classrooms for the duration of the exam.

They all agreed as they had prepared well in the last three days. The test consisted of 5 questions with total of 100 points:

### Richard Kuhn

Born 3 Dec 1900; died 1 Aug 1967 at age 66.Austrian biochemist who was awarded the 1938 Nobel Prize for Chemistry for work on carotenoids and vitamins. In 1933, Kuhn had discovered a third carotene isomer. It was called gamma-carotene because two other components were previously known in carotene, C40H56, a compound found in carrots. Those were the optically inactive alpha-carotene and the optically active beta-carotene (which rotates the plane of polarized light to the right). Initially, Kuhn was required by Hitler to refuse the award because Hitler was offended by the Nobel Peace Prize for Carl von Ossietzky in a Nazi concentration camp. Kuhn finally received his diploma and gold medal after World War II in 1949.«[EB and a NYT obituary give date of death 1 Aug 1967. DSB gives 31 Jul 1967.]
