101 Things I Learned in Engineering School

by John Kuprenas with Matthew Frederick

Engineering involves the application of mathematics, physics, and chemistry, but “the heart of engineering isn’t calculation; it’s problem solving,” writes John Kuprenas, a civil engineer. Here is a sampling of his insights.

“There’s always a trade-off. Lightness versus strength, response time versus noise, quality versus cost, responsive handling versus soft ride, speed of measurement versus accuracy of measurement, design time versus design quality… It is impossible to maximize the response to every design consideration. Good design is not maximization of every response nor even compromise among them; it’s optimization among alternatives.”

Water 4.0: The Past, Present, and Future of the World’s Most Vital Resource

by David Sedlak

David Sedlak is a professor of environmental engineering at the University of California, Berkeley. In this book he explains the history, science, engineering, and political aspects of water and sewer systems. First, it may be helpful to decode the title:

  • Water 1.0—a system of importing and distributing water.
  • Water 2.0—drinking water treatment including filtration and chlorination.
  • Water 3.0—sewage treatment.
  • Water 4.0—next-generation water systems.

I will focus on some of the more contemporary topics in this summary. Continue reading
