Bose - Einstein condensate
A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of weakly interacting bosons confined in an external potential and cooled to temperatures very near absolute zero (0 K or −273.16 °C). Under such conditions, a large fraction of the bosons occupy the lowest quantum state of the external potential, at which point quantum effects become apparent on a macroscopic scale.
This state of matter was first predicted by Satyendra Nath Bose and Albert Einstein in 1924–25. Bose first sent a paper to Einstein on the quantum statistics of light quanta (now called photons). Einstein was impressed, translated the paper himself from English to German and submitted it for Bose to the Zeitschrift für Physik which published it. Einstein then extended Bose's ideas to material particles (or matter) in two other papers.
Seventy years later, the first gaseous condensate was produced by Eric Cornell and Carl Wieman in 1995 at the University of Colorado at Boulder NIST-JILA lab, using a gas of rubidium atoms cooled to 170 nanokelvin (nK) (1.7×10−7 K). For their achievements Cornell, Wieman, and Wolfgang Ketterle at MIT received the 2001 Nobel Prize in Physics. In November 2010 the first photon BEC was observed. (read more) (see more)

You think that light is fast? Well, think again. Sometimes it is slower than a crawl. All schoolchildren know that light is the fastest thing there is. It zips along through empty space at 297,000 km per second (186,000 miles a second).
But now a Danish physicist and her team of collaborators have found a way to slow light down to less than 1.6 km per hour (one mile an hour) - slower than a slow walk.
The way Dr Hau and her team have slowed down light by a factor of 600 million or so is to use a group of atoms called a Bose-Einstein condensate (BEC). These atoms are cooled to a temperature of only a few billionths of a degree above absolute zero, the coldest possible temperature, at which all motion stops.
In a Bose-Einstein condensate, atoms are hardly moving at all. This means that according to the uncertainty principle that rules atoms, they are spread out and overlap. This results in a group identity for the collection of supercold atoms. And when light passes through such an environment, it will slow down.
By firing co-ordinated beams of laser light through the BEC, Hau and colleagues have slowed light down to a crawl. Inside the BEC, the so-called refractive index (which measures the slowing of light) becomes enormous: as high as 100 trillion times greater than that of glass. (news.bbc.co.uk)

Telepathy (from the Greek τηλε, tele meaning "distant" and πάθη, pathe meaning "affliction, experience"), is the transfer of information on thoughts or feelings between individuals by means other than the "five classic senses" (See Psi). The term was coined in 1882 by the classical scholar Fredric W. H. Myers, a founder of the Society for Psychical Research, specifically to replace the earlier expression thought-transference. A telepath is a person with the paranormal ability to read others' thoughts and mental contents. Telepathy is one kind of extrasensory perception which, along with psychokinesis, forms the main topics of parapsychological research. Many studies seeking to detect, understand, and utilize telepathy have been done within this field. This research has neither produced a replicable demonstration of telepathy, nor an accepted mechanism by which it might work. Hence the scientific community does not regard telepathy as a real phenomenon. It is hard to unambiguously distinguish telepathy from a number of other parapsychological hypotheses such as clairvoyance.
Although not a recognized scientific discipline, people who study certain types of paranormal phenomena such as telepathy refer to the field as parapsychology. Parapsychologists claim that some instances of telepathy are real. Skeptics say that instances of apparent telepathy are explained as the result of fraud, self-delusion and/or self-deception and that telepathy does not exist as a paranormal power.
Parapsychologists such as Dean Radin, president of the Parapsychological Association, argue that the statistical significance and consistency of results shown by a meta-analysis of numerous studies provides evidence for telepathy that is almost impossible to account for using any other means.

The Army has given a team of University of California researchers a $4 million grant to study the foundations of "synthetic telepathy." But unlike old-school mind-melds, this seemingly psychic communication would be computer-mediated. The University of California, Irvine explains:
The brain-computer interface would use a noninvasive brain imaging technology like electroencephalography to let people communicate thoughts to each other. For example, a soldier would "think" a message to be transmitted and a computer-based speech recognition system would decode the EEG signals. The decoded thoughts, in essence translated brain waves, are transmitted using a system that points in the direction of the intended target. (read more)
Ingo Swann (born Ingo Douglas Swan on 09/14/1933 in Telluride, CO) is an artist and author, best known for his work as a co-creator (according to his frequent collaborators Russell Targ and Harold Puthoff) of the discipline of remote viewing, specifically the Stargate Project. He has written several books on remote viewing or related topics.
Swann does not identify himself as a "psychic," preferring to describe himself as a "consciousness researcher" who had sometimes experienced "altered states of consciousness." Swann has stated, "I don't get tested, I only work with researchers on well-designed experiments." Swann is dissatisfied in a role as a passive subject. He feels he must contribute to the preliminary design of the research. According to Russell Targ and Harold Puthoff, there have been "Swann-inspired innovations" that have led to impressive results in parapsychology. Experiments not controlled by Swann have not been very successful. These are rarely mentioned, and if so, only in passing.
Swann helped develop the process of remote viewing at the Stanford Research Institute in experiments that cauught the attention of the Central Intelligence Agency. He is commonly credited with proposing the idea of Coordinate Remote Viewing, a process in which viewers would view a location given nothing but its geographical coordinates, which was developed and tested by Puthoff and Targ with CIA funding. Due to the popularity of Uri Geller in the seventies a critical examination of Ingo Swann's paranormal claims was basically overlooked by skeptics and historians. Uri Geller comments very favorably on Ingo Swann. Geller says, "If you were blind and a man appeared who could teach you to see with mind power, you would revere him as a guru. So why is Ingo Swann ignored by publishers and forced to publish his astounding life story on the Internet?" Both Geller and Swann were tested by two experimenters, Russell Targ and Harold Puthoff, who concluded that Geller and Swann did indeed have unique skills. However, others have strongly disputed the scientific validity of Targ and Puthoff's experiments. In a 1983 interview magician Milbourne Christopher remarked Swann is "one of the cleverest in the field." Details and transcripts of the SRI remote viewing experiments themselves were found to be edited and even unobtainable. (read more)

Wilhelm Reich (March 24, 1897 – November 3, 1957) was an Austrian-American psychiatrist and psychoanalyst, known as one of the most radical figures in the history of psychiatry. He was the author of several notable textbooks, including The Mass Psychology of Fascism and Character Analysis, both published in 1933.
Reich worked with Sigmund Freud in the 1920s and was a respected analyst for much of his life, focusing on character structure rather than on individual neurotic symptoms. He tried to reconcile Marxism and psychoanalysis, arguing that neurosis is rooted in the physical, sexual, economic, and social conditions of the patient, and promoted adolescent sexuality, the availability of contraceptives, abortion, and divorce, and the importance for women of economic independence. His work influenced a generation of intellectuals, including Saul Bellow, William S. Burroughs, Paul Edwards, Norman Mailer, and A. S. Neill, and shaped innovations such as Fritz Perls's Gestalt therapy, Alexander Lowen's bioenergetic analysis, and Arthur Janov's primal therapy.
Later in life, he became a controversial figure who was both adored and condemned. He began to violate some of the key taboos of psychoanalysis, using touch during sessions, and treating patients in their underwear to improve their "orgastic potency." He said he had discovered a primordial cosmic energy, which he said others called God, and that he called "orgone." He built "orgone energy accumulators" that his patients sat inside to harness the reputed health benefits, leading to newspaper stories about "sex boxes" that cured cancer. (read more)

There are only two ways to live your life.
One is as though nothing is a miracle.
The other is as though everything is a miracle.

The Mad Scientist
After his demonstration of wireless communication (radio) in 1894 and after being the victor in the "War of Currents", he was widely respected as one of the greatest electrical engineers who worked in America. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. During this period, in the United States, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture, but due to his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist. Never having put much focus on his finances, Tesla died impoverished at the age of 86.
The SI unit measuring magnetic flux density or magnetic induction (commonly known as the magnetic field "B"), the tesla, was named in his honor (at the Conférence Générale des Poids et Mesures, Paris, 1960), as well as the Tesla effect of wireless energy transfer to wirelessly power electronic devices which Tesla demonstrated on a low scale (lightbulbs) as early as 1893 and aspired to use for the intercontinental transmission of industrial energy levels in his unfinished Wardenclyffe Tower project.
Aside from his work on electromagnetism and electromechanical engineering, Tesla has contributed in varying degrees to the establishment of robotics, remote control, radar and computer science, and to the expansion of ballistics, nuclear physics, and theoretical physics. In 1943, the Supreme Court of the United States credited him as being the inventor of the radio.
