A perfect balance of science, history, and sociology, Time's Pendulum traces the important developments in humankind's epic quest to measure the hours, days, and years with accuracy, and how our concept of time has changed with each new technological breakthrough. Written in an easy-to-follow chronological format and illustrated with entertaining anecdotes, author Jo Ellen Barnett's history of timekeeping covers everything from the earliest sundials and water clocks, to the pendulum and the more recent advances of battery-powered, quartz-regulated wrist watches and the powerful radioactive clock, which loses only a few billionths of a second per day, making it nearly ten billion times more accurate than the pendulum clock. A tour of the discoveries and the inventors who endeavored to chart and understand time, Time's Pendulum also explains how each new advance gradually transformed our perception of the world.

this is my go to when needing new underwear.
Size: 3X-Large, Color: Black/Navy/Dark Purple/Red
Love these boyshorts for women. They're so comfortable, no crawling and breathable. I recommend for plus size women who has legs rubbing together causing irritation. Nice price as well. This is my go to when needing new underwear.

Great!
Size: Small, Color: Black/Heather Gray/White/Nude
Comfy, good fit, good quality cotton and flat seams around the crotch. Normal size small. I wouldn’t wear these with yoga pants, but nice under looser fitting garments. I would buy more colors.
