Answer the following question given this paragraph: 

Chemists are involved in the design and production of new materials. Some of the materials that chemists have helped discover or develop in recent years include polymers, ceramics, adhesives, coatings, and liquid crystals. Liquid crystals are used in electronic displays, as in watches and calculators. The silicon-based computer chip has revolutionized modern society and chemists have played a key role in their design and continued improvement. The calculator shown below uses both a liquid crystal display and chips inside the device.
