History Makers Series – serie

More than two centuries before Einstein, using a crude telescope and a mechanical timepiece, Danish astronomer Ole Romer measured the speed of light with astounding accuracy. How was he able to do this when most scientists didn’t even believe that light traveled? Like many paradigm-shattering discoveries, Romer’s was accidental. Night after night he was timing the disappearance and reappearance of Jupiter’s moon Io behind the huge, distant planet. Eventually he realized that the discrepancies in his measurements could have only one explanation: Light had a speed, and it took longer to reach Earth when Earth was farther from Jupiter. All he needed then to calculate light’s speed was some fancy geometry.

This is the story of how a farmboy became America’s foremost sculptor. After failing at academics, Dan was working the family farm when he idly carved a turnip into a frog and discovered what he was meant to do. Sweeney’s swift prose and Fields’s evocative illustrations capture the single-minded determination with which Dan taught himself to sculpt and launched his career with the famous Minuteman Statue in his hometown of Concord, Massachusetts.  This is also the story of the Lincoln Memorial, French’s culminating masterpiece. Thanks to this lovingly created tribute to the towering leader of Dan’s youth, Abraham Lincoln lives on as the man of marble, his craggy face and careworn gaze reminding millions of seekers what America can be. Dan’s statue is no lifeless figure, but a powerful, vital touchstone of a nation’s ideals. Now Dan French has his tribute too, in this exquisite biography that brings history to life for young readers.
