An I.Q. Test
Part of Einstein IQ Test
1) 12 members were present at a board meeting. Each member shook hands with all of the other members before & after the meeting. How many hand shakes were there?
2) At Probability University, there are 375 freshmen, 293 sophomores, 187 juniors, & 126 seniors. One student will randomly be chosen to receive an award. What percent chance is there that it will be a junior? Round to the nearest whole percent.
3) If you take a marker & start from a corner on a cube, what is the maximum number of edges you can trace across if you never trace across the same edge twice, never remove the marker from the cube, & never trace anywhere on the cube, except for the corners & edges?
4) A cube is made of a white material, but the exterior is painted black. If the cube is cut into 125 smaller cubes of exactly the same size, how many of the cubes will have 2 of their sides painted black?
5) In another galaxy, a certain nation of creatures speak a language known as Algramara. In this language, "harvec tood zevac" means "my tooth hurts," "lavec lina zevac" means "my delicious food," & "zevac corma lina" means "eating my food." What does "corma harvec zevac tood" mean?
6) If you started a business in which you earned $1 on the first day, $3 on the second day, $5 on the third day, $7 on the fourth day, & so on, how much would you have earned with this business after 50 years (assuming there are exactly 365 days in every year) - hint:fold in half?
7) A worker earns a 5% raise. A year later, the worker receives a 2.5% cut in pay, & now her salary is $22702.68. What was her salary to begin with?
8) How many weeks have 156 hours in them?
10) What letter completes this set?2k 2q 16p 4r 4b 4 - hint:pay raise/pay cut

FASCINATING PEOPLE, Part 18.
John Desmond Bernal (1901-1971) was a prominent international scientist from Ireland. He did pioneering work in X-ray crystallography. Was a Professor of Physics and a Fellow of the Royal Society. He ranged widely in his intellectual interests and activities, also doing pioneering work in social studies of science or "science of science". He was by all accounts a dazzling thinker and talker. His contemporaries called him SAGE, as he was considered to be uncommonly wise. He was a Marxist in philosophy and a Communist in politics (say, what?). Led a complicated life, sitting on hundreds of committees and playing a leading role in many scientific and political organisations. He also led a somewhat unconventional domestic life of a notoriously non-monogamous nature;~)
During the WWII Bernal was scientific adviser to Lord Mountbatten (the great grandson of Queen Victoria, who was a captain of the destroyer Kelly) . Worked with Solly Zuckerman on the impact of bombing on people and buildings. In 1943 he helped to select the landing beachers for the D-Day invasion of France...
He believed that scientific cooperation between nations would help to mitigate the difficulties caused by the cold war and lead to better understanding between countries. Science for international cooperation and for a world without war - well, he's good in my books!
