Improbable Research - Longest Running Experiments by Marc Abrahams We are happy to report that three of the world’s longest-running scientific experiments are indeed still running. It has been a number of years since anyone checked on all three. With assistance from scientists in several nations, we have managed to do so. Background on these Experiments In 1984, the European Journal of Physics published three remarkable reports, each describing a different experiment that had been continuing for decades. The Pitch Drop Experiment In Brisbane, pitch is dropping. As described by R. In the foyer of the Department of Physics at the University of Queensland in Brisbane is an experiment to demonstrate, for teaching purposes, the fluidity and the very high viscosity of pitch, set up in 1927 by Professor Thomas Parnell, the first Professor of Physics there. Here is the record as it was presented in 1984: A seventh drop fell during July 1988 during World Expo 88. Now, in the spring of 2001, the pitch is flowing as heartily as ever. The Beverly Clock
Equation Analysis Test/quiz/iq test your brain power! This test does not measure intelligence, your fluency with words, creativity or mathematical ability. It will, however, give you some gauge of your mental flexibility. few people have been found who could solve more than half of the questions on the first try. many, however, reported getting answers long after the testing had been set aside, particularly at unexpected moments when their minds were relaxed. some reported solving most of the questions over a period of several days. Take the test as your personal challenge. Some of them I have made up myself therefore you will not find the answers anywhere else on the web! Instructions: Each equation below contains the initials of words that make the statement true. If you get more than 15 Correct you will be eligible to add your name and score to the top scores here!
The Coming Technological Singularity ==================================================================== The Coming Technological Singularity: How to Survive in the Post-Human Era Vernor Vinge Department of Mathematical Sciences San Diego State University (c) 1993 by Vernor Vinge (Verbatim copying/translation and distribution of this entire article is permitted in any medium, provided this notice is preserved.) This article was for the VISION-21 Symposium sponsored by NASA Lewis Research Center and the Ohio Aerospace Institute, March 30-31, 1993. It is also retrievable from the NASA technical reports server as part of NASA CP-10129. A slightly changed version appeared in the Winter 1993 issue of _Whole Earth Review_. Abstract Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended.
Pitch drop experiment The University of Queensland pitch drop experiment, featuring its then current custodian, Professor John Mainstone (taken in 1990, two years after the seventh drop and 10 years before the eighth drop fell). University of Queensland experiment The eighth drop fell on 28 November 2000, allowing experimenters to calculate that the pitch has a viscosity approximately 230 billion (2.3×1011) times that of water. This is recorded in Guinness World Records as the world's longest continuously running laboratory experiment, and it is expected that there is enough pitch in the funnel to allow it to continue for at least another hundred years. This experiment is predated by two other still-active scientific devices, the Oxford Electric Bell (1840) and the Beverly Clock (1864), but each of these have experienced brief interruptions since 1937. Professor Mainstone subsequently commented: Professor John Mainstone died on 23 August 2013 following a stroke. Timeline See also
Museum of the History of Science How Stars Are Named How Stars Are Named The Ancient Arabic Names The brightest stars in the sky of Earth are also the ones with the most ancient names. Names such as Betelgeuse, Achernar, Sirius, Deneb, and Algol are usually Arabic, dating from around the tenth century when Arab astronomy flourished. Less-bright stars were usually not given proper names at the time, and were thus harder to talk about. The Bayer System In 1603, a German lawyer by the name of J. This system was not adhered to rigorously, though. The Flamsteed System Eventually, though, you’ll run out of Greek letters — there are only 24 of them, after all. The astronomical community accepted his new numbering scheme, but retained Bayer’s Greek-letter names for the brighter stars that already had them. Then the telescope came along The Flamsteed system worked just fine until astronomers started using telescopes.
Master monkey's brain controls sedated 'avatar' 18 February 2014Last updated at 11:35 ET By James Gallagher Health and science reporter, BBC News The brain of one monkey has been used to control the movements of another, "avatar", monkey, US scientists report. Brain scans read the master monkey's mind and were used to electrically stimulate the avatar's spinal cord, resulting in controlled movement. The team hope the method can be refined to allow paralysed people to regain control of their own body. The findings, published in Nature Communications, have been described as "a key step forward". Damage to the spinal cord can stop the flow of information from the brain to the body, leaving people unable to walk or feed themselves. The researchers are aiming to bridge the damage with machinery. Match electrical activity The scientists at Harvard Medical School said they could not justify paralysing a monkey. The master had a brain chip implanted that could monitor the activity of up to 100 neurons. Reality or science fiction?

Milgram's Obedience Experiments | The Perils of Obedience By Kendra Cherry Updated December 16, 2015. If a person in a position of authority ordered you to deliver a 400-volt electrical shock to another person, would you follow orders? Most people would answer this question with an adamant no, but Yale University psychologist Stanley Milgram conducted a series of obedience experiments during the 1960s that led to some surprising results. These experiments offer a compelling and disturbing look at the power of authority and obedience. More recent investigations cast doubt on some of the implications of Milgram's findings and even question the results and procedures themselves. Learn more about the experiments, the results and some of the major criticisms of Milgram's infamous research. Introduction to the Milgram Experiment "The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man is as the kind of situation in which he finds himself that determines how he will act."
