Explore the earliest electronic computers, including Charles Babbage's Analytical Engine. Although Babbage was not able to completely build it out before his death, his "engine" was based on the same four components that define computers today-input device, some type of memory to store data and temporary calculations, a calculating processor, and an output device.

In the 1880s, Heinrich Hertz proved that the high-frequency phenomena of light and heat are also electromagnetic waves and Nikola Tesla invented the "Tesla coil" which served as the basis for the radio oscillator. A few years later, radio signals were sent and received across the Atlantic Ocean. Examine the developments that led to the television monitor and then the emergence of digital TV.

Description
Stressing that he is not a medical doctor, Professor Cotter delves into the healthful and harmful effects of geologically sourced substances. Some have proven benefits, such as the antibacterial properties of salt and copper. Others can be deadly. For example, radon, a gaseous product of radioactive decay, causes lung cancer. Asbestos, a fibrous silicate mineral, is similarly dangerous to breathe.

Starting with the concept of strata-parallel layers of sedimentary rock lying one atop the other-learn how to look at a cliff face and read the strata like an epic adventure. The story can encompass hundreds of millions of years, involving advancing and retreating glaciers, falling and rising seas, the ebb and flow of life, and much else. Work up to the paragon of stratigraphy, the Grand Canyon.

Reading rock samples like the pages of a book, Professor Cotter recounts the stories they tell of change across vast stretches of time. He presents three key concepts that will open your mind to the fun and fascination of practical geology. Then he focuses on the idea of deep time, noting that humans have been around for only an infinitesimal fraction of Earth's 4.6-billion-year geologic drama.

Trace the history of oil exploration and recovery, focusing on the geology of petroleum and natural gas formations. To strike oil, you need to find a source rock, a reservoir rock, a caprock, and a structural feature called a trap where oil can pool. Survey some of the world's most productive oil fields, and investigate the plusses and minuses of hydraulic fracturing, also known as "fracking."
