# Birthday lunch – picnic style!

The family celebrated Sharmila’s birthday with a picnic lunch at Fainting Goat Winery. Usually we celebrate her birthdays in a different country but this once Covid pushed us to North Georgia mountains. We picked up the lunch from Old Mulehouse in Jasper. The wait for food was a little tedious but the taste was totally worth the wait. First time in a long time the whole family went out for a picnic and card games!! JayJay had the best time of his life!

# Book Review: Here’s looking at Euclid

This is an absorbing book if you have any cursory interest in numbers and how they came about. Alex Bellos, a British journalist has a good story telling style and presents fairly well some of the mysteries behind numbers.

For example, did you know…
… if we did not go thru math classes, we would naturally think of numbers in logarithmic scale? We would think 1,2,3, a few, many… We understand ratios better than differences. (Remember that example from a previous post on why we would not walk 50 yards to buy a car for one buck less but will do so for a 2-buck coffee?).

… that base 10 is very inconvenient? 12 is the most convenient base (explaining 60 minutes to an hour, 12 inches to a foot…). But 10 became standard because it was easier to count with our fingers that way. Ever wondered why a finger is also called a ‘digit’?

… there are some fascinating stories about Pi. You can read about them in a prior post here

… why do we call a variable “x”? Originally we used upper case vowels for variable and consonants for constants. Descartes switched to lower case. He denoted variables from the end… “z”, “y”… and constants from the front “a”, “b”… But while publishing his book, the printer started running out of “z”s and asked if he could use “x”. (there was not much use of “x” in words). Descartes replied that he did not care. The rest became history. If not for the printer running out of letters, we could have had Z-Rays to check your chest infection today or Malcolm Z !!

… what an ambigram is? See this post on how I now have started writing my name in ambigram.

… that the largest number smaller than 1 simply does NOT exist?

… that leaves tend to sprout out at 137.5 degrees relative to the previous leaf? (if you see from the top of the shoot) This is rooted in the Golden Ratio and Fibonacci sequence. (It maximizes the sunlight the plant can get regardless of the number of leaves)

… (speaking of Fibonacci numbers)… that most flowers have petals that is a number in the Fibonacci sequence? So do the spirals in a pineapple, spruce cones, sunflowers…

This and many other fascinating facts that our teachers never used to make math really interesting to us can be found in this book. You do not need to know math to enjoy this easy reading book

Highly recommend it.

# From the bartender’s corner – Poinsettia

This is a holiday favorite. Made it for Thanksgiving dinner. One was a mocktail.
Stir 3 ounce of cranberry juice and an ounce of cointreau in ice. After they have cooled down and mixed well, pour it in a flute glass. Top it off with chilled champagne. (there should be at least 3 ounces of champagne).

# 4 miles on Thanksgiving Day

Doubled the distance to 4 miles. Also went back to the new pair of shoes. Best part of the run? The calf pain did not resurface. Hopefully two months of rest has finally gotten rid of it…

# Some quiet contemplation on this day of giving thanks

My usual coffee places were closed (today is Thanksgiving Day in the USA). But found a Starbucks that is open and is allowing customers to sit outside in the open (also can use the restrooms).

Nobody else was around (other than some drive in customers in their cars). Very quiet and cloudy morning.

# Random picture

Can you guess what this picture is about?

It is the back of a chair that got drenched by the overnight rain…
