Both sides of a sensitive problem are assessed by Professor Gellhorn in this penetrating analysis of national security and its effect upon scientific progress.
The costs and advantages of secrecy in certain areas of science and the conflict between national safety and individual rights in the administration of our federal loyalty program are presented; all the arguments are objectively weighed. The book answers such questions as: Can young scientists be well trained when publication and teaching are not free? Have we gone far enough-or too far-in avoiding "security risks" in important scientific establishments? How does the federal drive against "potentially disloyal" persons actually work? Do "fear of the smear" and crude methods discourage public service by American scientists?

Explore the mysterious origin of the Universe, the evidence of advanced civilizations of tremendous antiquity, and the possible lineage of their builders.
The Hubble Telescope has revealed that there are more than two trillion galaxies in the observable universe. To put this in perspective, if you hold a single grain of sand at arm's length against the night sky, the tiny patch of sky it hides contains more than 100,000 galaxies -- not 100,000 stars, 100,000 galaxies.
"The human mind is not capable of grasping the universe. We are like a little child entering a huge library. The walls are covered to the ceilings with books in many different tongues. The child knows that someone must have written these books. It does not know who or how. It does not understand the languages in which they are written. But the child notes a definite plan in the arrangement of the books, a mysterious order which it does not comprehend, but dimly perceives." -- Albert Einstein

Redwoods thrive for centuries in the coastal regions of America's Pacific Northwest. Rooted by a river, they weather storms, survive ever more frequent floods, and resist fires, both those that spread along the ground and those that leap from ridge to ridge and crown to crown. Seeming to have no natural enemies, the trees endure increasing encroachment as they pass through thousands of seasons. Entwined at root and crown, they remind us that our lives, always separate and always interconnected with others, flow through time.

Many of us have wondered whether there's extra-terrestrials, aliens or an advanced civilizations out there and whether they have visited earth, leading us to one of humanity's biggest unanswered questions.
At first glance it seems unlikely that we're the only intelligent life that exists across trillions and trillions of miles of universe, but with possible government cover-ups, skeptics, and millions of people claiming aliens don't exist, it's time to dive deep into the UFO files and explore the existence of intelligent life outside of earth.
After spending years researching UFO sightings, lights in the sky, videos, reports, abductions, well-known stories, events you probably didn't even know happened, and visiting Roswell twice, I feel it is time to share the answers I have found, the connections to the cases and my logical to approach to answer the question of all questions... ''Are we alone in the universe?''
I'm going to share all of it in this book, to offer, what I believe ...
