		I hope the Sunlight Foundation’s is able to reach that critical mass.
		The key participants and featured players in the experiment are obviously the individual reporters with beat responsibilities who want to give it a try.
		They should be people with the kind of knowledge, insight, experience, perspective or contacts that are likely to be valuable to the reporter, given the issues the beat visits.

	Neptunium Goes Critical At Los Alamos
		A full-controlled criticality of the element neptunium was achieved in late September at Los Alamos National Laboratory's Technical Area 18 using a six kilogram nickel-clad neptunium sphere in combination with approximately 60 kilograms of enriched uranium.
		The experiment was conducted using the "Planet" assembly device at the Los Alamos Critical Experiments Facility or LACEF.
		During the experiment, measurements are taken as the lower section is raised and brought closer and closer to the upper section until sufficient mass of fissile materials is present and criticality is achieved.

	Criticality Accidents
		The criticality radiation alarm system functioned as designed, the evacuation of personnel from the building was prompt and orderly, and the excursion was terminated expeditiously by a negative coefficient of reactivity and was prevented from recurring by the action of the safety devices.
		The purpose of the particular experiment in progress was to establish the critical concentration of a sphere of the solution of uranyl nitrate surrounded by a thick water reflector.
		Prompt critical was obtained by dropping a slug of UH in styrex through a vertical hole in a small assembly of the same material, which was diluted with polyethylene and reflected by graphite and polyethylene.

	Critical experiment (Site not responding. Last check: )
		In the sciences, an experimentum crucis, orcritical experiment, is an experiment capable of decisivelydetermining whether or not a particular hypothesis or theory is correct.
		It is not unusual in the history of science for theories to be developedfully before producing a critical experiment.
		A famous example in the 20th century of an experimentum cruciswas the expedition led by Arthur Eddington to Principe Island in Africa in 1919 to record the positions of stars aroundthe Sun during a solar eclipse.

	NESU (Nijmegen Experiment SetUp) - Max-Planck-Institute for Psycholinguistics
		Experimenting in the late 80's and in the 90's changed dramatically, since with the arrival of the PC many more experiment computers became available.
		From our experience we knew that this was only possible if we were able to provide a specification interface for the user which was very simple to use and which could be used by experimenters for a very high percentage of experiments in a self-supporting manner.
		The experiment runner has a number of unique features such as opening several experiments simultaneously, running multi-subject experiments, automatic hardware presence detection, test of all low-level device functions, an option to directly change experiment parameters and the short comprehensive trial applet, and a pause/resume option.

	Critical Viscosity of Xenon
		The objective of the experiment is to produce archival viscosity data on xenon that is closer to its liquid-vapor critical point than is possible in Earth’s gravity.
		The main objective of the CVX experiment was to measure the viscosity of xenon within 0.3% of the critical density and to within 0.6 mK of the critical temperature Tc, which is 30 times closer than can be measured on Earth.

	Critical Thinking-Comprehesion-based Education
		As performance-based education appears less and less likely to produce students who can perform anywhere but in a classroom, educators are looking for something to make learning stay with students from grade to grade, and from the classroom to life.
		“Critical Thinking” is fast becoming the educational catchphrase of the day, and many public schools are requesting hundreds of thousands of dollars to experiment with more critical-thinking, comprehension-based approaches to learning.
		And, unlike the current push for critical thinking education, the critical thinking emphasis in BJU Press textbooks isn’t an experiment.

	Critical Viscosity of Xenon (CVX) (Site not responding. Last check: )
		Although the critical temperature and viscosity can differ greatly among fluids, there is a remarkable regularity: within experimental error the relative size of the viscosity increase is the same for all pure fluids.
		Zeno shone laser light into a sample of xenon near the critical point and measured the scattered light's "twinkling" caused by the growth and decay of the large density fluctuations.
		However, the experiment is designed for remote control to ensure that the most careful viscosity measurements are made closest to T c and to allow the timeline to be modified if the observed equilibration is faster or slower than predicted.

	Critical Bands by Masking Lab
		To determine if critical bands, as determined by masking, are the same for all frequencies.
		This is a send of finding the limit or size of the critical band and an example of what is needed to answer the question posed for th experiment.
		However, in many psychology experiments, all of the conditions have to be set up before the data collection begins because of the nature of testing groups of subjects.

	Dayton Miller's Ether-Drift
		His experiments yielded systematic periodic effects which pointed to a similar identifiable axis of cosmic ether-drift, though of a variable magnitude, depending upon the season, time of day, density of materials shielding or surrounding the apparatus, and altitude at which the experiment was undertaken.
		While the purpose of these experiments was not to measure any ether-drift or variation in the speed of light, such variations in fact were observed and reported in their paper.
		The experiment is designed to detect a very minute effect on the velocity of light, to be impressed upon the light through the ether itself, and it would seem to be essential that there should be the least possible obstruction between the free ether and the light path in the interferometer.

	As Elections Near, Officials Challenge Balloting Security - washingtonpost.com
		Diebold and some officials have criticized Sancho's experiments and said his conclusions about the vulnerability of electronic voting systems are unfounded.
		Critics have not demonstrated that any real elections have had returns altered by the manipulation of electronic voting systems.
		He is also critical of state officials who he believes should have caught the vulnerabilities earlier.

	Critical experiment (Site not responding. Last check: )
		In the sciences, an experimentum crucis, or critical experiment, is an experiment capable of decisively determining whether or not a particular hypothesis or theory is correct.
		A given theory which is in accordance with known experiment but which has not yet produced a critical experiment is typically considered worthy of exploration in order to discover such an experimental test.
		A famous example in the 20th century of an experimentum crucis was the expedition led by Arthur Eddington to Principe Island in Africa in 1919 to record the positions of stars around the Sun during a solar eclipse.

	Common Threads in Research Across Disciplines: A Reflection - Logistics
		A well-designed experiment can be a “critical experiment” that powerfully discriminates between competing hypotheses with a minimum of resources, but only if it is well thought out.
		One of the most frustrating of experiences is to expend great energy in a research activity and learn at the end little or nothing because of a poorly designed experiment.
		The Logistics Phase of research is essential to an efficient inquiry, and it is a delight to observe a master experimentalist design a critical experiment that with elegance and efficiency of effort winnows the possibilities.

		Don'’t get your hopes up though, there are five remaining freshwater dolphins that still exist in the world, all of which are critically in danger of disappearing forever.
		Researchers wanted to know if confusion over using copyrighted material in the classroom was affecting teachers attempts to train students to be critical of media.
