About the Pitch Drop Experiment While the School of Mathematics and Physics at The University of Queensland has an international reputation for cutting-edge research and innovative teaching in the disciplines of Mathematics, Physics and Statistics, it is also home to the famous Pitch Drop Experiment. The experiment is listed in the Guinness Book of World Records as the world's longest-running laboratory experiment. The first Professor of Physics at UQ, Professor Thomas Parnell, began an experiment in 1927 to illustrate that everyday materials can exhibit quite surprising properties. The experiment demonstrates the fluidity and high viscosity of pitch, a derivative of tar once used for waterproofing boats.

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

Des plaques d’égouts japonaises Au Japon les plaques qui recouvrent les bouches d’égouts sont souvent décorées et peintes avec des motifs représentant une spécialité de la ville où elles sont installées ou rendent hommage aux personnels qui les utilisent. ( Via ) 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!

Abstract Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended.

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."

Spooky Physics Phenomenon May Link Universe's Wormholes Wormholes — shortcuts that in theory can connect distant points in the universe — might be linked with the spooky phenomenon of quantum entanglement, where the behavior of particles can be connected regardless of distance, researchers say. These findings could help scientists explain the universe from its very smallest to its biggest scales. Scientists have long sought to develop a theory that can describe how the cosmos works in its entirety. Currently, researchers have two disparate theories, quantum mechanics and general relativity, which can respectively mostly explain the universe on its tiniest scales and its largest scales. One prediction of the theory of general relativity devised by Einstein involves wormholes, formally known as Einstein-Rosen bridges. Intriguingly, quantum mechanics also has a phenomenon that can link objects such as electrons regardless of how far apart they are — quantum entanglement.
