For those without a voice
I caught a cold over the weekend, and by Saturday night I had lost my voice. I reasoned, however, that I would still be able to communicate with people; I could just send them a text message.
Of course, people without voices were able to communicate well before text messaging was invented. If you have recently visited the tymshft page on Facebook, you will see that I recently shared a picture from the Peoria Historical Society. The picture included the caption
Ancient iPad in the PHS collections.
Needless to say, it was not an iPad, but a slate. PHS links to PBS, which describes the history of these communication devices:
In early schools, each child owned a book-sized writing slate encased in a wood frame. This was used for practicing script and it traveled to and from school with the student each day. The student scratched the slate with a slate pencil, which was a cylinder of rock. Eventually, the slate pencil was replaced by soft chalk, making it easier to write.
Today, of course, classrooms use whiteboards.
And text messaging.
