When Volume One of The Way Things

Work was published it was praised on

every hand. In the words of Time Maga-

zine: "In this technological age, the

world has long been divided into two

camps. There are those who want to

know how the complex machines that

are so much a part of their lives really

work; and there are those who couldn t

care less, as long as the machines some-

how keep functioning. For those who

nourish any technical curiosity at all,

this lucid book provides a thorough col-

lection of answers."

Now this second and new volume of

the now-classic illustrated encyclope-

dia of technology provides 171 more

concise, lucid explanations (each one

clearly illustrated with a facing diagram)

of the principles, processes and ma-

chines of the industrial age, from the

simple to the complex-

-from aerosol sprays to SCUBA ap-

paratus,

--from VTOL aircraft to color televi-

sion (explained in full color),

--from silos and silage to time-divi-

sion multiplexing,

--from safety binding for skis to mine

ventilation,
