History of solar wind and space plasma physics revisited. (arXiv:1301.1971v1 [physics.hist-ph])

History of solar wind and space plasma physics revisited. (arXiv:1301.1971v1 [physics.hist-ph]):
A paper published by Scottish geophysicist J.A. Broun in 1858 contained
several pioneering and remarkable ideas in solar-terrestrial physics. He could
anticipate more or less correctly the nature and origin of solar wind, solar
magnetic fields, sunspot activity and geomagnetic storms in the middle of the
19th century. Broun applied the experimental results of the behavior of ionized
gases in discharge tubes for the first time to Space Physics which may be
considered as the beginning of the astrophysical plasma physics. In this
context he attempted to explain the plasma interactions of solar wind with the
comet tails and earth's magnetosphere. Most of the postulates or hypotheses put
forward by Broun in 1858 and later in 1874 was rediscovered during the 20th
century, after the advent of Space age.

FLASHBACK: WHAT THE FOUNDING FATHERS SAID ABOUT GUNS

FLASHBACK: WHAT THE FOUNDING FATHERS SAID ABOUT GUNS:
Militias. Distrust of government. Abuse of power. The right to bear arms. Not a day passed without a passionate article or an editorial on the role of guns in American life. The year was 1775. More than 200 years later, the seminal debate undertaken as John Adams, Thomas Jefferson and James Madison formulated the laws of the land still echoes. Is the Michigan Militia an aberration or the Constitution in action? Is Gordon Liddy a dangerous demagogue or a devoted patriot? What exactly did the founding fathers mean when they penned the Second Amendment? No sampler can do justice to the debate, but we hope the following scrapbook helps shed light on the relation between arms and liberty. Our sources were Alexander Hamilton, Madison and John Jay's Federalist, "That Every Man Be Armed: The Evolution of a Constitutional Right," by Stephen Halbrook, "The Road to the Bill of Rights," by Craig Smith, and a collection of quotes compiled by Charles Curley.
