Best "Nontechnical" Physics Books

Does anyone have any suggestions on some good nontechnical books on physics? I want to know more about the history of science, lives of the scientists, etc., but I'm not necessarily opposed to something with equations and discussion on theories either. What I really mean by nontechnical is anything that isn't a formal paper or textbook. I'll read about any topic really, but right now I'm interested in the less mainstream type of theories. Not futuristic Kaku type science fiction-science, but just lesser known ideas. I know I could search on Amazon and get some good results, but I'm looking personal suggestions. Help me out?

Anything by John Gribbin, (no I'm not his agent or related to him in any way).

In translation from the original Latin, Italian, or German, the revolutionary scientific writings of Copernicus, Kepler, Galileo, Newton, and Einstein are here gathered into one monumental book. The texts appear to be unexpurgated, with little evidence of editing; Hawking's contribution is a biographical introduction to each of these icons of physics. The actual texts are largely unmediated by Hawking, so readers seriously willing to plunge into De revolutionibus or Principia mathematica would be well advised to be self-reliant, particularly in the mathematics absolutely central to understanding when reading the texts. This collection could be regarded as an intellectual fashion accessory for readers without the requisite mathematical ability, although some of the entries are more accessible, as with the Galileo offering, which Galileo wrote as a dialogue precisely for a general audience. . . .

On January 1, 1925, thirty-five-year-old Edwin Hubble announced findings that ultimately established that our universe was a thousand trillion times larger than previously believed, filled with myriad galaxies like our own. It was a realization that reshaped how humans understood their place in the cosmos. Six years later, continuing research by Hubble and others forced Albert Einstein to renounce his own cosmic model and finally accept the astonishing fact that the universe was not immobile but instead expanding. The story of these interwoven discoveries includes battles of will, clever insights, and wrong turns made by the early investigators in this great twentieth-century pursuit, from the luminaries (Einstein, Hubble, Harlow Shapley) to the lesser known: Henrietta Leavitt, who discovered the means to measure the vast dimensions of the cosmos . . . Vesto Slipher, the first and unheralded discoverer of the universe’s expansion... Georges Lemaître, the Jesuit priest who correctly interpreted Einstein’s theories in relation to the universe... Milton Humason, who, with only an eighth-grade education, became a world-renowned expert on galaxy motions... and others.
