August 15 - Panama Canal!

 Posted on August 15, 2021


This is an update of my post published on August 15, 2010:


After ten years of work, the 48-mile (77-km) Panama Canal was finally completed. 

And, on this date in 1914, the Panama Canal was officially opened.

It linked the Atlantic and Pacific Oceans and cut in half the trip from the East Coast of the U.S. to the West Coast.



That's huge!

You know what else was huge? Digging the canal! It was a huge and difficult engineering project. The French tried to build a canal in the same location in the late 1800s, and 21,900 workers died (mostly from tropical diseases) before they finally gave up the effort. The U.S. canal construction wasn't as deadly, but 5,600 workers lost their lives before the canal was finished.




Did you know...?

It takes from eight to ten hours to travel the canal.



At each elevation, a ship has to wait in each lock until the
water level has been raised or lowered to the level of the next lock.


The maximum size of ship that can use the canal is called Panamax.



Although the Pacific Ocean is west of the Atlantic, crossing from the Pacific to the Atlantic involves going the opposite you would think: from (south)east to (north)west. This is because the narrow chunk of land where the canal is built is a sort of “S” curve.



Word Play

Do you know what a palindrome is? It is a word or phrase that reads the same backwards or forwards. The words “mom” and “level” are both palindromes.

The Panama Canal is the subject of one of the longest and most famous palindromes:

A MAN, A PLAN, A CANAL – PANAMA



August 16 - Palindrome Week

Posted on August 16, 2018


Because the year of a written date is often written with the first two digits missing - making 2018 into just 18 - and because this is the eighth month of the year, this week has been Palindrome Week in the U.S. (In much of the world, the day is written before the month in a date, and for entire swaths of Asia dates are written year-month-day...so this is not Palindrome Week for any other nation.)

Actually, the palindromes of Palindrome Week will be going on a bit longer than a week.

You may already know that palindromes are words or numbers that are the same backwards or forwards. Examples include MOM, MADAM, NURSES RUN, 101, and 45,654.

Well, this chunk of August has included: 

8-10-18

8-11-18

8-12-18

8-13-18

8-14-18

8-15-18

8-16-18 (today!)

and will include:

8-17-18

8-18-18

8-19-18

If you take out the punctuation, the numbers are the same backwards or forwards.

May 10 – Palindrome Day

Posted May 10, 2015

 In the U.S., today is 5-10-2015.

Take out the date-dividers, and it's 5102015.
Read this number backwards, and it's 5102015.

In other words, exactly the same!

Palindromes are words or numbers that read the same backwards and forwards. Every time the numeric form of a date is a palindrome, we declare it Palindrome Day!

We don't get to celebrate Palindrome Day all that often. Pretty much just once a year.

Here are a list of the next few:

  • June 10, 2016 6-10-2016
  • July 10, 2017 7-10-2017
  • August 10, 2018 8-10-2018
  • September 10, 2019 9-10-2019
  • February 2, 2020 02-02-2020
  • January 20, 2021 1-20-2021
  • December 2, 2021 12-02-2021

However, most European countries write the day first, then the month and the year. So they have different Palindrome Days:

  • 5 October 2015 5-10-2015
  • 6 October 2016 6-10-2016
  • 7 October 2017 7-10-2017
  • 8 October 2018 8-10-2018
  • 9 October 2019 9-10-2019
  • 2 February 2020 02-02-2020
  • 12 February 2021 12-02-2021

One Palindrome Day is on both lists. Can you spot it?

Palindromes are usually words such as Dad, madam, or racecar. Remember, the definition of a palindrome is that it is read the same backwards or forwards. Some people enjoy creating palindromes that are phrases or entire sentences. The longer they are, the sillier they tend to be. For example:
Eva, can I stab bats in a cave? Was it a car or a cat I saw?

Some are just really good advice:
Step on no pets.

Some people even have palindromic names. A Japanese novelist and manga writer, Nisio Isin, often writes his name in a way to emphasize that it is an palindrome:
NisiOisiN

Here are a lot more palindromes, and here are some links for more palindrome activities – including palindrome word squares!
