Found an Old Schooldesk The Viewmaster My grandparents kept the Viewmaster in the top drawer of the side table in the den. Every Friday when my sister Jody and I would visit them, we would promptly take the plastic machine out, spread out all of the reels, and start clicking away. The Viewmaster was developed in Oregon by a company named Sawyer's. Like the stereoscope, it afforded 3D viewing, but because The Viewmaster used full color Kodachrome film rather than printed postcards, the images were crisper. Originally the Viewmaster focused on geographic and scenic imagery. Our grandparents were world travelers and they made sure to bring the world to our fingertips. My sister remembers flicking through Rome; I was rather impressed with Hawaii. Jody says, "I guess at the time without cable or Video or DVDs I was hungry for images that included broader scopes of the world." Later on, stills from popular TV shows and children's stories were included. Hands down, my sister and I loved the Barbie reels the most. But we also liked Laugh In and Dark Shadows. Thinking back, my sister liked the privacy of the whole viewing experience a la Viewmaster. I, however, remember that we'd argue about whose turn it was to look through and pull the trigger. For the most part though, we shared nicely, passing the Viewmaster between us, and commenting on the decor of Barbie's home.

Technology du jour: The DeJur The world headquarters of Vocabulary SpellingCity is located in an office building in Ft. Lauderdale, Florida. The building, like most, is serviced by a cleaning crew. One evening one of the workers dropped off this DeJur vintage film projector.

When the Mayor of Spelling City saw it, he didn't recognize it as one of his own dusty doohickeys. He promptly asked his team about it. Someone said, "The cleaning lady brought it a few nights ago." The curious mayor stayed late one evening to ask her about it.

The cleaning woman said the projector was "junk from her attic," but after seeing all machines in the office, thought she would add to the collection. The mayor smiled, thanked her, and handed her an appreciative cash token. The projector was last seen in good company high up on a shelf.

Return of the Slide Rule

When I posted the first blog about the slide rule, my very creative friend Terri from California was quick to comment and send a photo (above). Her father, O.J. Gilmore, a University of Nebraska Engineering grad, was a slide rule-carrying aeronautics specialist. A professor of O.J.'s bequeathed a Vector Type Log Rule to him upon graduation and from then on it was safely stowed in his briefcase. Apparently this particular rule is a very valued model.

After Terri wrote to me, I remembered that another dear friend, Charlotte, was the daughter of an engineer. I emailed Charlotte and asked if she might have any fond slide rule memories. I caught my friend and fellow writer on the verge of a deadline, but she responded regardless. "My dad had various size slide rules all over the house, in their little cases, and I was fascinated with them but never saw him use one!"

And since we're on the subject, just one more photo.
This circular slide rule is also part of Vocabulary SpellingCity's permanent collection of educational technology. And with that I conclude my portion of this blog devoted to the logarithm-loving device that I will surely never know how to use.

One more thing, the Apollo Program including the trip to the Moon was based on calculations mostly made on....SLIDERULES!

Speaking of classic technology, check out the old chemistry set. And remember the best way to get a well educated science population is to start with a solid elementary science program.
Posted by Jane Dagmi at 7:46 PM No comments: The Polaroid Polaroid cameras offered immediate gratification. While photography in general was amazing, the ability to see the picture within minutes of taking the picture was an astounding novelty and innovation.

Before digital photography revolutionized picture taking, Polaroid film produced results quickly and allowed us to see our marvels as well as our mistakes. Used in work and for fun, the Polaroid enjoyed a reputation as the ultimate party camera. Invented by Edwin Land, and first sold in 1948, images started developing inside the camera and then continued for another minute once outside. The familiar mechanism sounded and spit out a murky image which, after some arm waving back and forth, went from fuzzy to fine before our eyes. Little did we know back then, that waving it dry was completely unnecessary. This diagram was printed in The Golden Handbook "Photography: The Amateur Guide to Better Pictures (copyright 1956 by Simon & Schuster). The handbook is co-authored by two University of Illinois professors, one of education and the other of science education. In the forward they write:

"Photography, in just a century, has become a great medium of communication. It is a universal language, equally effective whether its task is factual or fanciful, scientific, artistic, or recreational."

Regarding photography and photographic equipment in the 60's and 70's, Vocabulary SpellingCity's mayor and techno-collector remembers, "We took pictures with cameras that had flash bulbs. The Polaroid was incredibly cool back then. I remember when the Instamatic arrived and you could 'point and shoot.' Today, that all sounds unbelievably quaint!" Labels: Edwin Land, Old Cameras, Photography, Polaroid

The Slide Rule Here are two slide rules. I don't know how they work. John, the Mayor of VocabularySpellingCity used a slide rule in high school physics and chemistry. He says, "I used to use it pretty well."

I visited The International Slide Rule Museum to find out what "using it well" would mean, but the answer was beyond my comprehension. I went to my personal library and perused The Young People's Science Encyclopedia from 1966. I thought, for sure, I'd get it since I am already an adult.

There, a slide rule is defined as:
"a mechanical instrument for doing mathematical problems more easily -- mostly multiplication and division. It consists of movable pieces of wood containing logarithmic scales and matching antilogarithms."

I was still lost. I can't remember what a logarithm is and the amount of energy I would need to spend in order to relearn it, could perhaps power a small village. The right side of my brain is limited compared to the left.

I'd be much obliged if someone could enlighten me just a smidge by completing the sentences below: A slide rule is handy if an engineer needs to ________________.
An architect might use a slide rule to calculate ________________.
The easiest task you can do with a slide rule is ________________.
It was cool when we used the slide rule to figure _______________.

I asked John if he wore the slide rule in his front shirt pocket as a symbol of mathematical wizardry. I had fond visions of the stylish engineering geeks at my alma mater sporting pens and other pocket-size tools. He did not, but kept his in his book bag.

As a substitute teacher and homework-supervising mom, I have witnessed much pencil sharpening -- both successful and frustrating, both annoying to the ear and disruptive to the class, and always messy. In between the cheap dollar sharpener that lurks in each student's desk or crayon box and the loud electric sharpener that breaks much too often, lies this classic vintage hand-operated Boston Champion.

According to the curators at The Early Office Museum, Boston brand mechanical sharpeners emerged on the scene 100 years ago. There were many models; the Champion was just one. Plenty of vintage ones abound on eBay. Pricing starts below $10.

Ever wonder about the history of the pencil? Here's an even better article from Pencils.com.  To quote and paraphrase a little:
... pencils descend from an ancient Roman writing instrument called a stylus. Scribes used this thin metal rod to leave a light, but readable mark on papyrus (an early form of paper). Other early styluses were made of lead, which is what we still call pencil cores, even though they actually are made of non-toxic graphite.

Could some linguist help me with why the word pencil has a c instead of an s in it?

To tout the simple, no-nonsense merit of the Boston Champion and other similar manual metal sharpeners, here's a little story a la Goldilocks and the Three Bears made up by one of the creatives in our office (ie Jane Dagmi...)

Goldilocks often went to the Three Bears' house to do her homework. She and Baby Bear would do their math independently, and then later compare answers. One day, Goldilocks arrived early at their cottage in the woods. The bears were still out foraging, but the headstrong girl with shiny blond hair, made herself at home anyway.

Goldilocks sat down in the kitchen and took out her work. She reached inside her knapsack for a pencil. The first one she found had a broken tip. She reached back in and pulled out a second. Its point was dull. She stuck her head in the bag and found no others. "Oh, I do hope the Bears have a pencil sharpener!" Goldilocks exclaimed.

She walked over to the kitchen counter with pencils in hand. She first found a big black electric sharpener. "This must be Mr. Bear's," Goldilocks thought. She stuck the first pencil in and the hungry machine chewed the pencil to bits, nearly taking her finger with it.

She opened a drawer, and found a small sharpener inside that was shaped like a nose. "This must be Baby Bear's," she laughed and stuck the second pencil up one nostril for that is where the blade was cleverly concealed. She spun the pencil round and round and heard the familiar abrading sound. When she took the Ticonderoga out of the nostril, the pencil was annoyingly pointy only along one side. She put it back in and after several more revolutions heard the crunch of broken graphite. "This just won't do," she said, with a droplet of discouragement in her voice.

She walked toward the window, hoping the Bears might be in sight. She did not see them, but she did spy a Boston Champion sharpener on Mama Bear's desk. She approached the device, and inserted the remainder of the second pencil into the hole. Goldilocks turned the hand crank 7 times for good luck. The Boston Champion honed the tip perfectly. It was just right and Goldilocks blurted out, "Woo hoo!!!"

The History of Educational Technology

Here is a relevant presentation on Educational Technology that I found:

Posted by BBat50 at 4:37 PM 1 comment: That Sound of Music In 2010, John Edelson's big holiday gift was a phonograph. The Newcomb Audio Products record player was a present from his wife. “Since John got interested in old educational stuff,” she says, “it’s gotten really easy to get him gifts.”

John took his new old phonograph to work, and instantly incorporated into his office décor. He also played it for the Time4Learning staff at the next meeting. Jennifer Eaton has been working on shaping this homeschool curriculum with John for five years, and has witnessed his collection grow. She confirms, “He gets very excited when he gets a new addition. So excited that he shows us how it works, and how it was made, etc.”

I wasn’t present at the phonograph’s debut show-n-tell, but was eager to listen to its sound. I wanted to hear the familiar crackling static that has the power to transport me back to 1973 in the pink shag carpeted bedroom that I shared with my sister. Or even to the oak entertainment console where my mother stored her many Burt Bacharach albums.

I turned the knob on John's record player, and very carefully placed the needle onto the record. After a revolution or two at 45 RPM’s, I heard that nostalgic crackle followed by the super sweet voice of the female singer. What was a delight for me was a fright for my fourth grader. Sammi covered her ears and hastily pleaded, “Ooh mom, turn that off. That’s scary.” She said the singer's voice reminded her of a clip from a horror movie that she once saw.

Now it’s your chance to listen……….

STAY TUNED: John’s record collection Walk in Peace Martin Luther King, Jr. was born on January 15, 1929. Today we are celebrating him. I interrupted my daughter and her friend in the middle of a game and asked, "Why do we celebrate Martin Luther King?" Here are snippets from their response:

"He made it so everyone can be together... He changed our lives so blacks and whites can go to the same schools, same bathrooms and same shoe store...so black people don't have to sit in the back of the bus...he had a dream for blacks and whites to be together."

They spoke passionately and elaborated about the time he and his father went into a shoe store and refused to sit in the designated section, and then were sent out without being able to buy shoes. I love how girls remember this story and feel the injustice when it comes to not being allowed to buy the shoes of your choice.

We are grateful for Martin Luther King's courage and conviction. Because of him and other noteworthy predecessors and followers, most of us can peacefully walk in the shoes of our choice and anywhere we desire.
Posted by Jane Dagmi at 10:48 PM 1 comment: My Manual Typewriter - Just My Type John’s early portable Smith Corona has already starred in a former blog, but I felt the desire to revisit the topic, and to praise this machine from my own point of view.

Growing up, we had one typewriter in our house. It sufficed. My mother, who had been a secretary, was an excellent typist. The only other device with a keypad was a new push-button Princess phone.

I learned to type in high school on a portable typewriter in Ms. Lentz’s typing class. She would put on a Beatles record, and the class would tap along to the beat. I specifically recall flourishing to “Maxwell’s Silver Hammer.” In those days (I am referring to the very early 1980s) we didn’t pick up the skill out of necessity to communicate efficiently with our friends via text or IM. Typing back then was an acquired and valued skill that could land a good typist a nice administrative job.

A few more thoughts about this universal icon with timeless appeal...

I think old typewriters are romantic. Movie set designers know this well, and use these bygone machines in period dramas or when depicting passionate, sentimental writer types. My vote for the most romantic use of an old-fashioned typewriter is in Baz Luhrmann’s "Moulin Rouge." The story takes place in early 1900s Paris, where a penniless Bohemian writer falls in love with a captivating yet terminally ill courtesan. Armed with an Underwood, the writer/poet taps out a love story, with plenty of internal struggle, in a light-filled dilapidated garret.

I think old typewriters can be a bit scary too. Screenwriters know this well, and have equipped some of the nastiest screen villains with them. Criminals have a notion that they are less likely to get caught if sending machine-made ransom notes or threats. In “The Jagged Edge” for example, lawyer Teddy Barnes is smitten with the man she is defending of murder until she discovers a Smith Corona hidden (not very well) in his closet. She quickly feeds the paper around the platen and types, “He is innocent.” The “t” is raised in exactly the same manner as the “t” in the anonymous typed notes she has been receiving throughout the trial. Teddy takes the machine, makes a speedy exit, and later despairingly tells her deceitful and murderous lover, “I found the typewriter.” I think there’s always a way to recycle cool old things like typewriter parts. Jewelry designers know this well, and repurpose the graphic keys to make stylish bracelets, earrings, cufflinks, and pendants. I have a bracelet that reads “edit.” A close friend of mine who is an Adjunct Professor, clinical psychotherapist, and appreciator of the past has a set of typewriter key earrings. When she bought the pair, it brought her back 50 years. In Professor Deborah Grayson’s own words:

“I used to love the sound of the clicking and tapping of the ‘stadium seating’ keys on the vintage, black Remington of the 1960's as my Mom would masterfully type out our term papers in high school- zing! zing! zing! All of the sounds of the keys tap dancing were sheer music, especially the zip, zip, zip of the paper carriage moving the words up and out of the typewriter. I can only imagine how she would've tweeted, blogged or texted! She was fast. I remember that in those days, she typed 180 words per minute. I love keeping those memories close...” (this last photo was taken by me while watching "Moulin Rouge" for the 87th time.)
