Apples, Corn, and Deer

I have always been fascinated by the fact that the French word for potato is "apple of the earth" (pomme de terre). As is often the case, these little word puzzles that tickle your brain for years turn out to be the tip of a linguistic iceberg.  

Apples of an orange tree

Originally, all fruits were 'apples'.  For example, what we now call an 'orange' was originally the apple of the orange tree!  Eventually, we just dropped all the extra words and just called the fruit of that tree by the name of the tree (etymologically, the orange tree came first then the fruit and then the color).  I don't want to upset the applecart since you are the apple of my eye but the French are not so strange for talking about an apple of the earth. Most ironic of all is the expression "apples and oranges" (meaning you are talking about two completely different things and they should be talked about separately). How do you like them apples?  

Maize or Corn


Let me take a second bite at that apple: It turns out that corn is the apple of the grain world.  While it is true that corn is technically a fruit, what I mean here is that, originally, corn was the generic term for grain. What we call 'corn' in America was originally Indian corn. Corn can be wheat, oats, rye, etc. depending on where you live.  That's why the French call it maïs; they are using the original word for Indian corn, maize. 

While researching for this post, I discovered that a deer used to refer to any four legged wild animal.  I always thought it interesting that a specific type of item could become the name of a category ("Pass me a Kleenex"), but never knew that the name of the category could become a specific item. Language and words are such slippery beasts, aren't they? Words are all contextual!

Hart or Deer

Oh dear, I guess the apple does sometimes fall far from the tree, linguistically speaking.  (Don't worry, I realize this post is kind of corny...)

Le mis-en-bouteille familiale

Irene just showed me this amazing video in her Facebook feed from the family winery in Corsica:

In the background you can see my cousin and her father (Ton Ton!) working the bottling facility.  To see the two of them working together really brings me true joy.  Also, the bottling facility was added in the years after I worked in the winery so I've never seen it operational before.

Binary Code

I used to think it so strange that the digital world is binary.  Everything computers do eventually gets boiled down to zeroes and ones; gates that are open or closed.  How can they do such complex tasks?



Then, I realized that DNA is binary*.  Sure there are four base pairs but there is only one entry per rung: either G-C or A-T.  All these people... all these life forms on this planet! How can there be such variety?



Then, I realized that charge, spin, quarks, and many other fundamental particles and their attributes are also binary (positive or negative; up or down; matter or antimatter; boson or fermion).  Either the excitation in the field exists (and you have a particle) or it doesn't.  



The Universe is binary*!

*Maybe not binary exactly but certainly based off of limited number of discrete possibilities.

Rideouts in a Pandemic

So far, the four of us have managed to do one family thing every single day.  Most of the day, we may be online in different corners of the house, but at least once a day we get together to play a game or watch a show together.

The most recent is a new game (a father's day gift from Irene!):

Star Trek (TOS) Catan !!

An Early Teaching Story

I was reminded of one of my classic stories by the recent discovery of this picture of my first AP Physics class from Swampscott (2004?):


Note how my bald spot is super visible when I'm writing on the board.

-------------

So, I'm teaching this freshmen class (not the one pictured above!) and I turn my back to the class in order to write something at the very top of the board.  This girl in the front row whispers to her friend "Oh, he has a bald spot!".  Now, I'm sure she meant to be discrete but the class was very quiet and she was only about three feet behind me.  I figure this is an opportunity too good to pass up.

I slow my writing down and stop.  Without turning around, I slowly cap my marker.  As I turn around, this girl (pretty sure her name was Skyler) visibly slinks down in her chair and starts to stammer "Oh, Mr. Rideout I didn't mean..." 
I interrupt with a slightly annoyed gesture saying "It's okay.  But, you know, a man gets to be a certain age... and he gets sensitive about his appearance."  She slinks even lower into her chair.

"But that's okay, because it's got me thinking about ... thinking about ... religion."

At this point the entire mood of the class goes from bemusement/anxiety to intrigue and puzzlement.  Skyler stop slinking towards to the ground and looks surprised.

"You know, people choose their religions all wrong.... Oh my parents are such and such so I will be too.... or, oh I like this one philosophically... or, I like the traditions and sacraments of this one.... all these common ways are the wrong ways to go about it."

"What you gotta do is think about the fashion accessories.  That's right, choose your religion based on the fashion accessories folks:  Want to rock out a big cross on a necklace:  Christianity is for you my friend.  Looking to cover up with some sweet head gear:  Islam may be your calling.  Got a nice little bald spot that a yarmulke would be the perfect size to cover up?  Yes, indeed, I'm thinking I should be Jewish!"

At this point everyone is laughing and Skyler has come back to normal sized and is smiling.  Little did I know she was Jewish!  Later that semester, when we broke for the seasonal holiday, I became the first goy to get the gift of a yarmulke for Christmas...

The Price You Pay

So, I might sometimes rickroll my students via group emails.  Maybe I go on a little TOO long about how much I admire Dr. Derek Muller of Veritasium fame.  It's possible I talk about my kids and my blog too much.  

If you end the year by having your students do short video explainers you may pay the price for these indiscretions:

1.  Three students are explaining the physics of stringed instruments and end with this:


2.  Two students are explaining some uses of SONAR and make some surprising discoveries:



3. Three students are explaining harmonics and overtones:

4.  One student ends her presentation with a completely gratuitous but excellent Titanic reference:
