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:

Theodore MaimanDied 5 May 2007 at age 79 (born 11 Jul 1927).Theodore Harold Maiman was an American physicist who built the first working laser. He began working with electronic devices in his teens, while earning college money by repairing electrical appliances and radios. In the 1960s, he developed, demonstrated, and patented a laser using a pink ruby medium. The laser is a device that produces monochromatic coherent light (light in which the rays are all of the same wavelength and phase). The laser has since been applied in a very wide range of uses, including eye surgery, dentistry, range-finding, manufacturing, even measuring the distance between the Earth and the Moon. |
