The embryonic development of femtoscience stems from advances made in the generation of ultrashort laser pulses. Beginning with mode-locking of glass lasers in the 1960s, the development of dye lasers brought the pulse width down from picoseconds to femtoseconds. The breakthrough in solid state laser pulse generation provided the current reliable table-top laser systems capable of average power of about 1 watt, and peak power density of easily watts per square centimeter, with pulse widths in the range of four to eight femtoseconds. Pulses with peak power density reaching watts per square centimeter have been achieved in laboratory settings and, more recently, pulses of sub-femtosecond duration have been successfully generated. As concepts and methodologies have evolved over the past two decades, the realm of ultrafast science has become vast and exciting and has impacted many areas of chemistry, biology and physics, and other fields such as materials science, electrical engineering, and optical communication. In molecular science the explosive growth of this research is for fundamental reasons. In femtochemistry and femtobiology chemical bonds form and break on the femtosecond time scale, and on this scale of time we can freeze the transition states at configurations never before seen. Even for n- reactive physical changes one is observing the most elementary of molecular processes. On a time scale shorter than the vibrational and rotational periods the ensemble behaves coherently as a single-molecule trajectory.

With recent major breakthroughs in ultrafast laser technology and femtosecond nonlinear spectroscopic techiques, Femtosecond Laser Spectroscopy is currently a burgeoning field in many branches of science, including physics, chemistry, biology, and materials science. There is an urgent need for researchers and postgraduate students to have a volume which includes the major research efforts currently in practice around the world and all under one cover.

A fascinating history of U.S. presidential vacation spots—collected for the first time in one guide that covers everything from Mount Vernon to Kennebunkport to Camp David.Where do you go to relax when you’re the leader of the free world? Even the president needs to get away from it all sometimes. From George Washington to Barack Obama, each of our presidents has sought solace from the tightly structured daily routines of the White House. As Ronald Reagan once said of his California ranch, “I do some of my best thinking there.” Peter Hannaford takes readers on a fascinating armchair vacation with each of our leaders, offering unique historical context for the why and the where of their chosen retreats. Which president asked visiting foreign dignitaries to send him seeds to plant at his family home? Who called his vacation property “Sherwood Forest” because it was “a good place for an outlaw”? Which adventure-loving Commander-in- Chief set up a Summer White House in New York every year? Who liked to cruise aboard the presidential yacht when faced with momentous wartime decisions? Who polled the American people to help him decide where to vacation? Presidential Retreats explores a side of the American presidency that we don’t often see—the downtime—as it offers an intriguing glimpse at the evolution of leisure time in this country.

Australia is dying of thirst. The northern half of the continent has become an independent Islamic state. The remaining territories have amalgamated into the United States of Southern Australia, with the exception of Tasmania, which has joined the emerging economic powerhouse of New Zealand.Cattle and sheep can only be raised in the Muslim state of Capricornia. Meat production in USSA is dependent upon the farming of kangaroos, and water has become more valuable than oil.Despite a respectable history of peace and stable international relations, three school-leavers in the central Capricornian town of Whitlam form a terrorist cell. In Canberra, a disillusioned security chief plots to enhance his agencys funding. And in what was once South Australia, the half-Aboriginal descendant of an eccentric itinerant works on a kangaroo farm. He dreams.Will the future of central Australia be determined by arrogance, malice, and incompetence?

For most of three decades, Drew Pearson was the most well-known journalist in the United States. In his daily newspaper column-the most widely syndicated in the nation-and on radio and television broadcasts, he chronicled the political and public policy news of the nation. At the same time, he worked his way into the inner circles of policy makers in the White House and Congress, lobbying for issues he believed would promote better government and world peace. Pearson, however, still found time to record his thoughts and observations in his personal diary. Published here for the first time, Washington Merry-Go-Round presents Pearson’s private impressions of life inside the Beltway from 1960 to 1969, revealing how he held the confidence of presidents-especially Lyndon B. Johnson-congressional leaders, media moguls, political insiders, and dozens of otherwise unknown sources of information. His direct interactions with the DC glitterati, including Bobby Kennedy and Douglas MacArthur, are featured throughout his diary, drawing the reader into the compelling political intrigues of 1960s Washington and providing the mysterious backstory on the famous and the notorious of the era.
