Description

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.



One of history's greatest scientific achievements, 200 years ahead of its time, presented in graphic novel format.

STARRED REVIEW!

How the observation of a small anomaly in a distant moon's orbit led to a discovery of, literally, astronomical significance. Weston spins thin historical records into an account of the career of 17th-century Danish astronomer Ole Romer from schoolboy days through nights spent watching the skies through a self-built telescope at the court of Louis XIV to final years as a renowned scientist (and police chief). Noticing that Jupiter's moon Io seemed to speed up and slow down on a regular schedule as it passed behind its planet, Romer not only concluded that light did not propagate instantaneously (a radical notion then), but, using the relatively crude clocks and other instruments of the time, came up with a wrong but close estimate of its speed. Along with retracing Romer's line of reasoning, the author explains how other researchers of the time and later roughed out the distances between major members of the solar system and refined those measurements over time, then closes with nods to Einstein, astronomical distances, and light's truly mind-bending pace. Evans tucks diagrams and mathematical calculations as well as banter and fanciful details into her lighthearted cartoon illustrations, wedging single and sequential panels of Romer and others at work into views of starscapes and planetary surfaces. Human figures in the art are white and predominantly male. A significant, unjustly obscure highlight from modern science's early days. (timeline) (Informational picture book. 8-12)

"I really liked reading Finding the Speed of Light because it was educational. I loved that it was kind of like a comic book, with speech balloons. This made it fun to read. I also loved the illustrations. I would recommend Finding the Speed of Light: The 1676 Discovery that Dazzled the World to kids who wonder about science and astronomy and who want to learn about the speed of light." -- Jewel Age 11 - Kids' Book Buzz
" The unique combination of Weston's writing style and Evans' colorful, cartoon-like illustrations make this book a delight. This would be a great discussion starter for young scientists as they explore this text and note the process and missteps that go along with scientific investigation and inquiry. Recommended " -- Terry Roper, Library Consultant, Region 10 ESC, Richardson, Texas - School Library Connection Reviews

The shipping was just superior

The shipping was just superior; not even one of the books was in contact with the shipping box -anywhere-, not even a corner or the bottom, so all the books arrived in perfect condition. The international shipping took around 2 weeks, so pretty great too.
