Dr. Aris Thorne believed in three things: the ideal gas law, the tensile strength of stainless steel 316, and the absolute, unyielding authority of the copy of Sinnott & Towler’s Chemical Engineering Design, 5th Edition that lived on his desk.
"The book says 1.6." Aris tapped the page. "The book is based on fifty years of industry data. The vendor is trying to sell you a new $200,000 distributor. Who do you trust?"

Each suggestion had been met with a quote from Chapter 14 (Heat Transfer Equipment) or Chapter 22 (Safety and Loss Prevention). "Show me the design calculation," Aris would say, tapping the book. "Show me the margin." "The book is never wrong," he whispered
Tonight, that compass was pointing toward ruin.
