Paperback. Condición: Very Good. The Journal of Irreproducible Results is the funniest thing to happen to science since Archimedes ran naked through the streets of Syracuse. --Discover Science humor magazine The Journal of Irreproducible Results has targeted hypocrisy, arrogance, and ostentatious sesquipedalian circumlocution since 1955. JIR editor Norman Sperling presents humorous and quirky tidbits relating to science, math, academia, bureaucracy, and witty word play. More than 250 entries ponder and pun the practical and peculiar. Consider OSHA's definition of the word exit as compared to Merriam Webster's: OSHA states, Exit is the portion of a means of egress which is separated from all other spaces of the building or structure by construction or equipment as required in this subpart to provide a protected way to travel to exit discharge. Webster's defines exit as, A way out of an enclosed place or space.

Paperback. Condición: Fair. NATIONAL BESTSELLER * From one of the world's leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes "an astonishing ride" through the universe (The New York Times) that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton's unchanging realm in which space and time are absolute, to Einstein's fluid conception of spacetime, to quantum mechanics' entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.…

Hardback. Condición: Good. When it comes to Mars, the focus is often on how to get there: the rockets, the engines, the fuel. But upon arrival, what will it actually be like? In 2013, Kate Greene moved to Mars. That is, along with five fellow crew members, she embarked on NASA's first HI-SEAS mission, a simulated Martian environment located on the slopes of Mauna Loa in Hawai'i. For four months she lived, worked, and slept in an isolated geodesic dome, conducting a sleep study on her crew mates and gaining incredible insight into human behavior in tight quarters, as well as the nature of boredom, dreams, and isolation that arise amidst the promise of scientific progress and glory. In Once Upon a Time I Lived on Mars, Greene draws on her experience to contemplate humanity's broader impulse to explore. The result is a twined story of space and life, of the standard, able-bodied astronaut and Greene's brother's disability, of the lag time of interplanetary correspondences and the challenges of a long-distance marriage, of freeze-dried egg powder and fresh pineapple, of departure and return. By asking what kind of wisdom humanity might take to Mars and elsewhere in the Universe, Greene has written a remarkable, wide-ranging examination of our time in space right now, as a pre-Mars species, poised on the edge, readying for launch.…
