Reading Between the Lines
[1]
In , Norman Joseph Woodland, a graduate student at Drexel Institute of Technology, set out to solve a persistent problem for supermarkets: how to automate the tedious process of inventory checking and checkout. Standard methods relied on manual entry, which was slow and prone to human error. Woodland, along with his classmate Bernard Silver, began brainstorming solutions, but their initial ideas, which involved ultraviolet ink, proved impractical and expensive.

The breakthrough came in an unexpected setting. While visiting his grandfather in Miami, Woodland sat on the beach, pondering how to encode information visually. He idly ran his fingers through the sand, pulling four fingers toward him to draw parallel lines. Looking down at the patterns left behind, he had a sudden realization. He could adapt the concept of Morse code—a system he had learned in the Boy Scouts—by extending the dots and dashes vertically to create thin lines and thick lines. By reading these lines with a light source, a machine could instantly decode the information.

Woodland and Silver patented their "Classifying Apparatus and Method" in , but the technology required to read the code—including lasers and computers small enough to fit in a store—did not yet exist. It would take more than two decades, and the development of the microchip and helium-neon lasers, before the barcode would make its commercial debut. On June , , a pack of chewing gum was scanned at a supermarket in Troy, Ohio, marking the birth of a technology that would revolutionize global commerce and logistics.
Suppose the writer's goal had been to write an essay that details the collaborative efforts and equal division of technical labor between Norman Joseph Woodland and Bernard Silver in the commercialization of the barcode. Would this essay successfully fulfill that goal?
- AYes, because it describes how Woodland and Silver brainstormed initial ideas together and jointly patented their invention in .
- BYes, because it highlights how Silver's work with ultraviolet ink was key to the final laser-scanning technology implemented in .
- No, because the essay focuses primarily on Woodland’s individual breakthrough and subsequent technological developments rather than detailing a collaborative division of labor in commercializing the invention.Cevap
- DNo, because the essay indicates that Woodland and Silver abandoned their barcode project because the necessary laser technology did not exist in the s.
