You can help by adding to it. January Although practical jokes have likely existed for thousands of years, one of the earliest recorded hoaxes in history was the drummer of Tedworth in As the technology of communication has advanced, the speed at which hoaxes spread has also advanced: However, hoaxes could also be spread via chain letters , which became easier as the cost of mailing a letter dropped. The invention of the printing press in the 15th century brought down the cost of a mass-produced books and pamphlets, and the rotary printing press of the 19th century reduced the price even further see yellow journalism. During the 20th century, the hoax found a mass market in the form of supermarket tabloids , and by the 21st century there were fake news websites which spread hoaxes via social networking websites in addition to the use of email for a modern type of chain letter. Etymology[ edit ] The English philologist Robert Nares — says that the word hoax was coined in the late 18th century as a contraction of the verb hocus , which means “to cheat,” “to impose upon”  or according to Merrian-Webster “to befuddle often with drugged liquor. Barnum ‘s Fiji mermaid Robert Nares defined the word hoax as meaning “to cheat,” dating from Thomas Ady ‘s book A candle in the dark, or a treatise on the nature of witches and witchcraft.

Last week, I spent three half days with students of the Archaeology department of the University of Oslo. These are the students that will help me in my endeavours to conduct the first part of the arrow shaft experiments that we will undertake on the weekend of 20th st of April. I was excited to meet them, as I had gathered there was quite some interest building up towards the experiments.
Just to my liking! Although the Department actually has a room dedicated to experimental activities, this is mainly used for an introduction to flintknapping, and not all students choose to work with that module. However, the huge pile of waste flint on the floor did provide us with some excellent tools!
No one flinched at the idea.

Mary Ellen Ellis How did life originate on Earth? We may never have a complete and definite answer to that question, but in , chemist Stanley Miller conducted a famous experiment that would show how the early Earth could have produced the chemicals of life. Who Was Stanley Miller? Stanley Miller was an American chemist who conducted one of the most exciting experiments in modern science.

The researchers found that they could induce a large number of photons to have matching states, and they say it could help to make for superfast, reliable quantum computers. Scroll down for video A ‘quantum cat’ can be both alive and dead at the same time, existing simultaneously in two different places. This means if you measure, ‘up’ for the spin of one photon from an entangled pair, the spin of the other, measured an instant later, will be ‘down’ – even if the two are on opposite sides of the world.
Entanglement takes place when a part of particles interact physically. For instance, a laser beam fired through a certain type of crystal can cause individual light particles to be split into pairs of entangled photons. The theory that so riled Einstein is also referred to as ‘spooky action at a distance’. Einstein wasn’t happy with theory, because it suggested that information could travel faster than light. In the hypothetical experiment a cat is placed in a sealed box next to a radioactive sample, a Geiger counter and a bottle of poison.
The observer cannot know whether or not an atom of the substance has decayed, and consequently, cannot know whether the vial has been broken until the box is opened. This means the cat is both dead and alive inside the box, a mixture of both states, until the box is opened to reveal the cat as either dead or alive. In the new experiments, the researchers take this idea to the next level, adding an additional box to the scenario.
This makes it an ideal location to directly measure the curvature of the Earth, as Rowbotham wrote in Zetetic Astronomy: IF the earth is a globe, and is 25, English statute miles in circumference, the surface of all standing water must have a certain degree of convexity—every part must be an arc of a circle. From the summit of any such arc there will exist a curvature or declination of 8 inches in the first statute mile. In the second mile the fall will be 32 inches; in the third mile, 72 inches, or 6 feet, as shown in the following diagram: Earth’s rate of curvature as shown in Zetetic Astronomy.

Gwen Sharp, PhD on September 15, Jean Piaget, a psychologist who published his most influential works from the late s through the s, is most known for his theory of stages of cognitive development. He suggested a four-stage model that children go through as they develop more complex reasoning skills. In the preoperational stage Piaget said it lasted from around age 2 until about 7 , kids start being able to grasp symbols. For instance, they can draw a series of squares with a triangle on top to represent a house.
They also start to learn the alphabet, which is, of course, the set of symbols we use to read and write. By the concrete operational stage roughly years old kids comprehend ideas like weight, amount, and speed, and can understand that the amount of liquid in the two glasses is the same: They can also understand causal relationships, though not necessarily explain the reasoning behind them.
Here, the younger kid says what would happen if you hit a glass with a feather based on what he knows about feathers, whereas the older child reasons from the previous statement and answers according to the logic proposed despite it being obviously inaccurate: Finally, Piaget said that in the formal operational stage after about age 12 kids can understand abstract concepts and reason logically.
The girl in the last video, who reasoned from the previous statement which had been presented as true , illustrates formal operational thinking. Do we really only go through each stage once?

Det var studier af strata, lagdelingen af klipper og jordarter, som gav naturhistorikere det indtryk, at Jorden må have gennemgået mange ændringer i løbet af sin eksistens. Disse lag indeholdt ofte forstenede rester af ukendte skabninger, hvilket fik nogle til .
Participants were recruited and told they would participate in a two-week prison simulation. The team selected the 24 males whom they deemed to be the most psychologically stable and healthy. The prison had two fabricated walls, one at the entrance, and one at the cell wall to block observation. They were given rest and relaxation areas, and other comforts. Twelve of the 24 participants were assigned the role of prisoner 9 plus 3 alternates , while the other 12 were assigned the role of guard also 9 plus 3 alternates.
Zimbardo took on the role of the superintendent, and an undergraduate research assistant the role of the warden. Zimbardo designed the experiment in order to induce disorientation , depersonalization , and deindividuation in the participants. The researchers held an orientation session for guards the day before the experiment, during which guards were instructed not to physically harm the prisoners or withhold food or drink. In the footage of the study, Zimbardo can be seen talking to the guards: We’re going to take away their individuality in various ways.
In general what all this leads to is a sense of powerlessness. That is, in this situation we’ll have all the power and they’ll have none.

The Stanford Prison Experiment was a social psychology experiment that attempted to investigate the psychological effects of perceived power, focusing on the struggle between prisoners and prison was conducted at Stanford University between August 14–20, , by a research group led by psychology professor Philip Zimbardo using college students.
Zimbardo’s goals[ edit ] The archived official website of the Stanford Prison Experiment describes the experiment goal as follows: We wanted to see what the psychological effects were of becoming a prisoner or prison guard. To do this, we decided to set up a simulated prison and then carefully note the effects of this institution on the behavior of all those within its walls. Zimbardo’s primary reason for conducting the experiment was to focus on the power of roles, rules, symbols, group identity and situational validation of behavior that generally would repulse ordinary individuals.
The team selected the 24 applicants whose test results predicted they would be the most psychologically stable and healthy. The prison had two fabricated walls, one at the entrance, and one at the cell wall to block observation. They were given rest and relaxation areas, and other comforts.
For many the term science refers to the organized body of knowledge concerning the physical world, both animate and inanimate, but a proper definition would also have to include the attitudes and methods through which this body of Click the link for more information. Matter is sometimes called koinomatter Gr. Forms of energy include heat, light, sound, electricity, and chemical energy.
Energy and work are measured in the same units—foot-pounds, joules, ergs, or some other, depending on the system of Physics is in some senses the oldest and most basic pure science; its discoveries find applications throughout the natural sciences, since matter and energy are the basic constituents of the natural world.
