A Truth Table Day

I find out that Einstein created a series of riddles.  What is interesting is that in Einstein's time he considered only 2% would solve the riddle below.  In our time the creation of a logic grid (like a truth table) to manage boolean logic is common. Basic boolean logic dominated computer and information management disciplines by the 1970's.  Computer spreadsheets in the 1980's made possible the analysis and display of row and column data. It made complicated oral descriptions simple.  In fact, it seems to me that we completed the move from the oral tradition to the visual tradition with computer spreadsheets.  

The Einstein riddle comes from brainden.com

"It is said that this quiz was made up by the famous physicist and according to him 98% will not solve it.

There is a row of five different color houses. Each house is occupied by a man of different nationality. Each man has a different pet, prefers a different drink, and smokes different brand of cigarettes.
  1. The Brit lives in the Red house.
  2. The Swede keeps dogs as pets.
  3. The Dane drinks tea.
  4. The Green house is next to the White house, on the left.
  5. The owner of the Green house drinks coffee.
  6. The person who smokes Pall Mall rears birds.
  7. The owner of the Yellow house smokes Dunhill.
  8. The man living in the centre house drinks milk.
  9. The Norwegian lives in the first house.
  10. The man who smokes Blends lives next to the one who keeps cats.
  11. The man who keeps horses lives next to the man who smokes Dunhill.
  12. The man who smokes Blue Master drinks beer.
  13. The German smokes Prince.
  14. The Norwegian lives next to the Blue house.
  15. The man who smokes Blends has a neighbour who drinks water.
Who has fish at home? Are you one of the 2%?


Further Discussion"

Let's complete our 'truth table' with its metadata row along the top:  Occupant nationality, House colour, Cigarette brand, Drink type, Pet type.

Our garden pictures today come from the Denver Botanical Garden, so I guess our first picture would be titled Botanical Bunny.

A Note from Einstein

It was JazzFM that brought this story to my attention - a note written on a Tokyo hotel official paper in 1922 by Albert Einstein sold at an auction in Jerusalem, October 24, 2017 for $1.5 million. The headline of this interesting story: 

Einstein's Note on Happiness Sells for...
"While in Japan, Einstein stayed at Tokyo’s Imperial Hotel. During his stay, a hotel worker came to Einstein’s room to make a delivery. Einstein found himself without any money to give the man as a tip for his services.
So, instead of money, the famous scientist handed the hotel worker a signed note with a sentence he wrote in German. It read: “A calm and humble life will bring more happiness than the pursuit of success and the constant restlessness that comes with it.”
He gave him another note that read: “Where there’s a will, there’s a way.”
He advised the bellboy to keep these notes as they would become more valuable than a tip. 

We look at two elements in the garden today - a birch tree creatively displays bird houses in a Grimsby garden and bamboo leaves seen through the conservatory plexiglass window at the Royal Botanical Gardens.
