Slide Rules!

What is this exhibit?

From the late 19th century to the 1970s, analog slide rules were among the most common computing devices. Cheap to buy, quick to use. However, by the mid 1970s, digital pocket-sized calculators had replaced slide rules as the tool of choice for most scientists, engineers, and mathematicians.

Unique Design You may think that the slide rules only have traditional "ruler" shape. That's wrong! Just like computers, they have more than one geometric shape- They could also be circular or cylindrical.
