Hey, Operator

 

Won't you help me make this call?

On Father's Day, we were having lunch with our youngest granddaughter and her parents.  I told her that Mother's Day was the biggest day of the year for restaurants, while Father's Day was the biggest day for collect calls.  I was hoping that joke would elicit at least a chuckle. Rather, a puzzled look and .. "What's a collect call?".  Yet another confirmation of my passage into geriatric-hood. What was I thinking? A Gen-Z'er, born with a cell phone in the cradle, how would she possibly understand collect calls?

I went on to explain it used to be that that every 'long distance' call was individually charged to your phone bill, priced by the minute - long distance meaning any call that crossed out of the local telephone company's territory. A caller had the option to ask the operator to "reverse the charges" so the cost would show up on the callee's bill rather than your own. This feature was often used by children calling home. You just told the operator you wanted the call to be collect and she - always she - would connect the call and ask "Will you accept the charges?".  Another puzzled look .. "What's an operator?".  Deeper and deeper into the twilight zone.

So I had to explain 1950's phone technology. I could as well been speaking Urdu. Before age of the dial phone, an operator fielded every request and connected you to someone via a telephone switchboard.  You picked up the phone and heard "Number please?" and waited for the call to be put through. Our home phone number was 74.  The hardware's was 2.  Grandma was 35. Lowry telephone operators were also the watchdogs of Main Street.  I could pick up the phone and ask Inez or Leona if they knew where my dad might be. "Oh, I just saw him go into the cafe".  

Not knowing when to cut my losses, I then told her the story of coming down with the mumps during my senior year in high school and being forced into quarantine for 3 weeks or so. One boring Sunday afternoon, when my folks were out visiting - people actually did that back then, just drop in on someone for a visit - I decided to give Carol a call.  She lived on a farm about 5 miles away, but in another phone company's territory, so the call was "long distance".  (I didn't ask to reverse the charges!).  We talked for 45 minutes. When the phone bill arrived and my mother saw the mammoth $4.50 charge sticking out like a neon sign amongst the mostly 50¢ calls, she let me have it. "What could you possibly have to talk about on the phone for 45 minutes?"  Hmm, note to self: next time remember to reverse the charges. 

Finally coming to my senses and rejecting boldly going on to person-to-person calls & party lines, I decided to cease and desist.

So .. I've come to the realization that most of my great treasure of knowledge and a substantial block of my skillset is obsolete and of little interest to anyone - with a possible rare exception of another old geezer. 

Some of my now less than useful capabilities are things like .. 

  • Deftly digging out information from American Peoples Encyclopedia
  • Coupling cast iron soil pipe joints with oakum and hot lead  
  • BASIC Programming on a Commodore 64  
  • Operating a key punch machine
  • Clipping baseball cards to my bicycle spokes to turn it into a motorcycle 
  • Circling good stuff in the Sears Catalog
  • Drag bunting
  • Diagramming sentences
  • Operating a ditch-witch 
  • Bowling scorekeeping 
  • Operating the Burroughs posting machine
  • PowerPoint
  • Listing World Series winners from 1903 to present from memory - fyi, no series winner in 1904 or 1994 
  • Constructing a haystack - actually an embarrassing fiasco 
  • Assembling a hog feeder
  • Using a slide rule
  • Navigating with paper maps
  • Spelling
  • Weighing out 25¢ worth of 8p nails
  • Conjugating Latin verbs
  • Driving a stick shift pickup truck
  • Speaking broken German
  • FORTRAN IV
  • Twinkie baking
  • Writing cursive
  • Integrating to find the area under a curve 
  • Changing a fuse
  • Blogging
  • Proving a doughnut and a coffee cup are topologically equivalent - but not digestively
  • Knowing the way to San Jose
  • ...
It’s the beginning of a very long list. Not all is despair. I do have a list - shorter - of some still useful abilities.

In Defense of Mathematics


I taught mathematics for a living for 7 years and then went on to a career in computer programming, software development and management.  So I never asked the question "Why should I study this stuff? I'll never use it".  But I heard that whine over and over in my teaching days. Math seems to be the principal whipping boy for this critique. Do students ask "Why should I read Shakespeare? Why should I study Newton's 3 laws? Who cares about the Civil War?" What's the valence of sodium? Really?"  

Well, ok, sure they do.  But nevertheless, you don't necessarily know what's good for you.   

I would make the argument that math is beautiful, but that just brought eye-rolls.  I'd argue that math is the underpinning of all the science and if you want a career in science or science related, you better learn math. But the ultimate argument is that math teaches you how to think logically, and that is a skill that applies to most everything you do.  It's not about memorizing your times tables all the way up to 9x7 = 56 or all those word problems you struggled with [if a canoe is traveling 6 mph in Stillwater , how fast is it going in Hastings. - it's a nerd joke] or memorizing the quadratic equation.  These tasks build a foundation for logical, creative problem solving.

Math trains your brain. Much like physical activity helps keep your body fit, math keeps your mind nimble so you can avoid being intimidated by new tasks you might face.  And these brain calisthenics improve your memory - think Alzheimer's vaccine.  Not to mention, in this day and age of creeping AI, reasoning skills will help you identify scams rather than succumb to them. It's also not about being right all the time.  Math teaches you to try different approaches and to be persistent. 

There are loads of things in your life that are "mathematical", even if you don't realize it.

  • Board games, crosswords, sudoko, puzzles
  • Reflecting on the news. Understanding arguments, interpreting graphs and diagrams, box scores
  • Understanding financial information. Creating a budget.
  • Following recipe instructions
  • Math and music skills have a strong correlation. I hired a few music majors as programmers
  • Managing your prescription drugs. It's 10 mg AM & PM, not 20 mg every other day. 
  • Cheating on your golf score.
  • Calculating how much you've lost in your crypto account
  • Creating your itinerary for your next road trip
  • Navigating your way around a website
  • Making that difficult pool shot
  • Calculating your batting average
  • ...
You really should be asking yourself "when do I not use math?".

I have become increasingly concerned over American illiteracy in general - and math illiteracy in particular. Math needs defending.  It is massively under appreciated.  Someone's gotta do it.

Public Service Announcement

Is this post/website/document/photo/video legit?  With the advent of AI generated materials, that is the question you must always ask yourself - whatever you are reading, viewing or listening to. If it feels fishy, it probably smells that way as well. And don't click on those Facebook posts with the punch line cutoff or the "I will miss him.." clickbait. Be skeptical.  Truth is a precious commodity.  Make sure you are a truthy not a dupey. 



I have to keep harping on this because you are vulnerable and you need to pay attention. And in an election year,  you should be doubly diligent and expect a deluge of deepfakes.

For example:
  • An AI generated photo of an explosion near the Pentagon causes a stock market crash. 
  • A robo-call urging voters not to vote used an AI generated voice of President Biden.
  • Deepfakes  e.g. a new service claiming to use artificial intelligence (AI) “neural networks” and “generators” to create fake driver licenses and passports has reportedly succeeded in passing Know Your Customer (KYC) checks on multiple crypto exchanges.
  • Ransomware  Digital extortion
  • Vishing - voice phishing. Calls or messages to trick you to reveal personal or financial info
  • Zoombombing.  Hijacking video conferences
  • Biometric attack - using fake facial/voice recognition
  • Phishing - duping you to reveal identity information

Don't share any article or post unless you are absolutely positive that its source is legitimate. Don't be an artificial disseminator.  If 2 people share a false statement and those 4 people share and the next 8 people share, pretty soon you are at 2256 and that is a very large number.

From the Washington Post. Dec 18, 2023

“Some of these sites are generating hundreds if not thousands of articles a day,” said Jack Brewster, a researcher at NewsGuard who conducted the investigation. “This is why we call it the next great misinformation superspreader.”


Sensationalist newspapers and magazines used to be referred to as "Yellow Journalism". We now have Pink-slime journalism and it is an order of magnitude worse. It deliberately misrepresents.  The use of AI makes it easy to mimic legitimate news sites, images and even voices. Use reputable fact checking sites like PolitiFact, Snopes to verify the legitimacy of information.

Finally, here is a wealth of good information on how to recognize and avoid scams:  https://consumer.ftc.gov/articles/how-recognize-and-avoid-phishing-scams

Be careful out there.
