Good morning students and parents!

 

This is the 9th week of school and the 1st week of 2nd 9-weeks grading period.

 

A reminder that if any student is absent, they are expected to watch the video of that day’s lecture, found in the shared google folder, so that they are up to speed when they return. 

 

ALSO… I am in my room each school day by 7AM to assist any student needing extra help or for any student who is simply looking for a quite place to study.

This week on the Math Playground . . . 

MATH BIO:

Ferdinand Magellan (1480 – April 27, 1521) was a Portuguese sea explorer who sailed for Spain.

 

Ferdinand Magellan's voyage is the greatest sea journey in recorded history, the first voyage around the entire world.


In 1519, a group of 251 men set sail from Spain in five small wooden ships under the command of a Portuguese navigator, Ferdinand Magellan. Their voyage is the greatest sea journey in recorded history: the first voyage around the entire world. Against all odds, Magellan's skill and determination helped his crew reach their destination and eventually earned him the title of the greatest maritime explorer of all times. When Magellan embarked with his crew of men, he could not have known that his journey would take almost three years to complete, only one ship, the Victoria, with eighteen men aboard would return, and that he would not be among the survivors. (On April 27, 1521, while staying in the Philippines—which he discovered and named in honor of the Spanish King Phillip, he was killed when he took part in a battle between rival Filipino groups on the island of Mactan—shot in the leg with a poisoned dart.) Ferdinand Magellan's voyage changed the world. People will never think about their environment in the same way again.

 

MATH FACT:

Why do we have an International Date Line?  It comes down to math, of course.  Here’s the question we can pose.  Can a continuous one-to-one function from the circle to the real number line be found?  That is, can we define a way to “map” every single point on a circle to every point on the number lone?

 

Put it another way: is it possible, for every longitude on the earth, to assign a time so that each longitude has a different time, but the times at nearby longitudes are close?

 

In fact, NO. Any attempt to construct such a function will inevitably fail. Known formally in mathematics as the Borsuk-Ulam Theorem, this explains why the world has an "international date line": assigning time to geographical location is a function from a circle (longitude) to an interval (time).

 

By convention, we normally assign times in discrete chunks (time zones), but the idea is the same. Our current method says that if it is 10 AM on Wednesday in Claremont, then it is 11 AM in Denver, and 12 noon in Minneapolis. Continuing around the globe in this manner, one finds that to keep nearby points having nearby times, one would have to assign Claremont a different time as well--- 10AM on THURSDAY! The only other alternative is to give up the continuity in favor of one-to-oneness, and put the discontinuity along a longitude of the earth that would affect the fewest people, i.e., somewhere in the Pacific, and call the discontinuity a "date line".

 

Final note:

The 18 survivors of Magellan's expedition around the world were the first to present this dilemma for the bewilderment of all Europe. After three years westward sailing, they first made contact with European civilization again on Wednesday 9 July, 1522 by ship's log. But in Europe it was already Thursday!

 

MATH QUOTE: 

"In order to see whether we had kept an exact account of the days, we charged those who went ashore to ask what day of the week it was, and they were told by the Portuguese inhabitants of the island that it was Thursday, which was a great cause of wondering to us, since with us it was only Wednesday. We could not persuade ourselves that we were mistaken; and I was more surprised than the others, since having always been in good health, I had every day, without intermission, written down the day that was current."—Antonio Pigafetta, Magellen’s personal assistant and surviving member of the circumnavigation, upon completing the voyage.

 

LIMERICK:

Round the globe did the ships find their way,

At the end, though, the ship’s crew said, “Hey!”

For when they returned,

They were shocked to have learned

That they lost three whole years plus one day.

 

 

Have a great week,

Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost. Rigour should be a signal to the historian that the maps have been made, and the real explorers have gone elsewhere.--W.S. Anglin
