Carl Sagan Carl Edward Sagan (/ˈseɪɡən/; November 9, 1934 – December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. His contributions were central to the discovery of the high surface temperatures of Venus. However, he is best known for his contributions to the scientific research of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan always advocated scientific skeptical inquiry and the scientific method, pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). §Early life[edit] Carl Sagan was born in Brooklyn, New York.[4] His father, Samuel Sagan, was an immigrant garment worker from Kamianets-Podilskyi, then Russian Empire,[5][6] in today's Ukraine. My parents were not scientists. §1939 World's Fair[edit] §World War II[edit] §Scientific achievements[edit]
33 Mistakes Men Make While Having Sex (INFOGRAPHIC) Maybe you don’t know but women can handle your soft side. When it comes to personality you can be as soft as bloody filet mignon. But when we talk about bed time, your penis needs to be hard. Now, ladies, let’s be honest. Remember that the receiving process begins with the giving process. Click Here To Discover What Men Secretly Want, But They Could Never Tell You. Is Time an Illusion? (Video) “Time has no independent existence apart from the order of events by which we measure it.” —Albert Einstein Surprising as it may be to most non-scientists and even to some scientists, Albert Einstein concluded in his later years that the past, present, and future all exist simultaneously. In 1952, in his book Relativity, in discussing Minkowski’s Space World interpretation of his theory of relativity, Einstein writes: Since there exists in this four dimensional structure [space-time] no longer any sections which represent “now” objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more natural to think of physical reality as a four dimensional existence, instead of, as hitherto, the evolution of a three dimensional existence. Einstein’s belief in an undivided solid reality was clear to him, so much so that he completely rejected the separation we experience as the moment of now.
Making Sense of the Chemistry That Led to Life on Earth It was the actions of Jupiter and Saturn that quite inadvertently created life on — not the gods of the Roman pantheon, but the giant planets, which once orbited much closer to the sun. Driven outward, they let loose a cascade of asteroids, known as the Late Heavy Bombardment, that blasted the surface of the young Earth and created the deep pockmarks still visible on the face of the moon.
Blog Archive » Mr. X by Carl Sagan This account was written in 1969 for publication in Marihuana Reconsidered (1971). Sagan was in his mid-thirties at that time. He continued to use cannabis for the rest of his life. It all began about ten years ago. I can remember another early visual experience with cannabis, in which I viewed a candle flame and discovered in the heart of the flame, standing with magnificent indifference, the black-hatted and -cloaked Spanish gentleman who appears on the label of the Sandeman sherry bottle. I want to explain that at no time did I think these things ‘really’ were out there. While my early perceptions were all visual, and curiously lacking in images of human beings, both of these items have changed over the intervening years. The cannabis experience has greatly improved my appreciation for art, a subject which I had never much appreciated before. A very similar improvement in my appreciation of music has occurred with cannabis. There is a very nice self-titering aspect to cannabis.
Review of Galantamine: the Lucid Dreaming Pill So you’re considering the red pill… Galantamine has emerged as THE lucid dreaming pill. This natural supplement has been used for centuries in China as a memory enhancer, and was even noted by the ancient Greeks for its powerful mind-inducing effects. Now we know that galantamine indirectly promotes dreaming sleep as well as lucid dreaming, which is the art of becoming self-aware in your dreams. There’s a lot of hype about galantamine, so I want to cover the basics about how it works on the brain, the studies that have proven its effectiveness, and my personal recommendations for experimentation with this safe and natural supplement. I also want to be brutally honest about some of the mild psychological and physical side effects as well. Want to cut to the chase? Galantamine & Memory red spider lily (Lycoris radiata) Galantamine is found in the natural world in many plant sources, including the common daffodil (Narcissus pseudonarcissus).

A New Thermodynamics Theory of the Origin of Life Why does life exist? Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.” From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Kristian Peters Cells from the moss Plagiomnium affine with visible chloroplasts, organelles that conduct photosynthesis by capturing sunlight. “You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant,” England said. England’s theoretical results are generally considered valid.
Early humans domesticated themselves, new genetic evidence suggests When humans started to tame dogs, cats, sheep, and cattle, they may have continued a tradition that started with a completely different animal: us. A new study—citing genetic evidence from a disorder that in some ways mirrors elements of domestication—suggests modern humans domesticated themselves after they split from their extinct relatives, Neanderthals and Denisovans, approximately 600,000 years ago. “The study is incredibly impressive,” says Richard Wrangham, a biological anthropologist at Harvard University who was not involved in the new work. Domestication encompasses a whole suite of genetic changes that arise as a species is bred to be friendlier and less aggressive. Modern humans are also less aggressive and more cooperative than many of our ancestors. Giuseppe Testa, a molecular biologist at University of Milan in Italy, and colleagues knew that one gene, BAZ1B, plays an important role in orchestrating the movements of neural crest cells.
