Born during a short-lived marriage between the Romantic poet Lord Byron and an educated mathematician, Lovelace felt the pull of both the creative and scientific worlds. As a lonely and sickly young girl, Lovelace spent her hours building a flying machine and other inventions. While her mother pushed the study of mathematics on her, Lovelace often applied poetic and intuitive thinking to scientific concepts. It was during her work with mathematician Charles Babbage that she pushed the boundaries of technology. Lovelace s detailed notes on Babbage s Analytical Machine include a calculation method that has earned her recognition as the first computer programmer.

Explains the concept of general relativity. Scientists throughout history have made amazing discoveries, but few findings have rocked our world and our view of our place in the universe like the theory of relativity. Albert Einstein's observations and studies leading up to this game-changing discovery are recounted here, as are modern-day applications and current findings. This book also includes the contributions of other instrumental scientists and their studies, such as Galileo Galilei, Sir Isaac Newton, and James Clerk Maxwell. This engrossing story of the scientists and studies that lead to the theory of relativity will fascinate and educate history and science fans alike.

Looks at the history and evolution of freedom of the press in the United States, and examines threats to the principle in such areas as freedom of information, leaks of classified information, and police harrassment.
