Experiment, GA

An experiment is a procedure carried out to verify, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies.

A child may carry out basic experiments to understand gravity, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the natural and human sciences.

Experiments typically include controls, which are designed to minimize the effects of variables other than the single independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements. Scientific controls are a part of the scientific method. Ideally, all variables in an experiment are controlled (accounted for by the control measurements) and none are uncontrolled. In such an experiment, if all controls work as expected, it is possible to conclude that the experiment works as intended, and that results are due to the effect of the tested variable.

Experiment (game)

Experiment is a dedicated deck card game for 3-6 players designed by Tim De Rycke and Sander Vernyns.

The players are working in a lab where you are trying to get hold of the right colored fluids to mix them and fulfill the tasks that your professor assigned you. After 11 rounds the points of the accomplished tasks are counted. The one with the most points wins the game.

The game received the award for best prototype at the Games & Toys Awards in 2006. The price includes printing by Cartamundi and distribution by 999 Games. A second edition is distributed by SandTimer

Experiment (locomotive)

Experiment was a steam locomotive designed and built by Richard Roberts in 1833 for the Liverpool and Manchester Railway (L&MR). The locomotive had vertical cylinders driving via bell cranks.

Experiment (probability theory)

In probability theory, an experiment or trial (see below) is any procedure that can be infinitely repeated and has a well-defined set of possible outcomes, known as the sample space. An experiment is said to be random if it has more than one possible outcome, and deterministic if it has only one. A random experiment that has exactly two ( mutually exclusive) possible outcomes is known as a Bernoulli trial.

When an experiment is conducted, one (and only one) outcome results— although this outcome may be included in any number of events, all of which would be said to have occurred on that trial. After conducting many trials of the same experiment and pooling the results, an experimenter can begin to assess the empirical probabilities of the various outcomes and events that can occur in the experiment and apply the methods of statistical analysis.

Experiment (website)

Experiment, formerly called Microryza, is a US website for crowdfunding science-based research projects. Researchers can post their research projects to solicit pledges. Experiment works on the all-or-nothing funding model. The backers are only charged if the research projects reach their funding target during a set time frame. In February 2014, the site changed its name from Microryza to

It was founded in 2012 by Denny Luan and Cindy Wu, former University of Washington researchers. The former name Microryza is inspired by Mycorrhizae and symbiotic fungi that lives in the roots of plants.

Unlike the popular crowdfunding site Kickstarter, backers of Experiment projects do not get tangible rewards for backing. Researchers share the scientific process directly with the backers and become a part of the project.

Microryza charges an 8% fee (5% for Microryza and 3% for payment processing) only if the campaign is successful. If the campaign does not reach the funding goal, no one is charged.

As of Aug 26, 2014, they passed $1M raised on their platform.

Experiment (ship)

Many vessels have born the name Experiment:

Naval vessels
  • HMS Experiment, thirteen ships of the Royal Navy
  • USS Experiment (1799), a United States Navy schooner
  • USS Experiment (1832), a United States Navy schooner
Merchant vessels
  • Experiment, a horse powered boat
  • Experiment, launched in 1798, transported convicts to New South Wales in 1803
  • Experiment, launched in 1802, transported convicts to New South Wales in 1809-10

I began to think about the implications of this experiment I realized that, straightforward enough though the effect may be, it clearly does not conform to any simple associationist theory derived by an extension of pavlovian or skinnerian conditioning theory, whose essence is the immediate linking in time of stimulus and response.

Indeed, in Chapter 111 shall go on to show how our own experiments can prove that this is the case - with implications far different from those the associationists wish to draw from them.
