Chronologically presented, this book begins with Pythagoras (c. 580 BC-c. 500 BC) and ends with Stephen Hawking (b. 1942 -). As with all of the scientists featured in 100 Scientists Who Shaped World History, both men sought answers to the physical world around them. Pythagoras, a Greek philosopher and mathematician, coined the word philosophy, believed that mathematics and nature were harmonious and is best known for the Pythagorean theorem. Hawking, an English physicist, combined the theory of relativity with quantum mechanics to describe the properties of black holes.

As with the other titles in Bluewood's popular 100 Series, each entry in 100 Scientists Who Shaped World History includes an illustration or photograph and a locator map, accompanied by concise, clearly written text -- teeming with facts and nuggets of information. The book also has a complete index and trivia quiz. Perfect for both the browser who wants to read material in quick bites and for those who want to read the content comprehensively.

This survey addresses the use of technology in upper secondary mathematics education from four points of view: theoretical analysis of epistemological and cognitive aspects of activity in new technology mediated learning environments, the changes brought by technology in the interactions between environment, students and teachers, the interrelations between mathematical activities and technology, skills and competencies that must be developed in teacher education. Research shows that the use of some technologies may deeply change the solving processes and contribute to impact the learning processes. The questions are which technologies to choose for which purposes, and how to integrate them, so as to maximize all students' agency. In particular the role of the teacher in classrooms and the content of teacher education programs are critical for taking full advantage of technology in teaching practice.

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.
