An interactive Fortran IV program is described which allows the orientation matrix of a crystal to be determined and refined without ambiguity, from a transmission or reflection Laue photograph. The indexing method is that of Riquet & Bonnet [J. Appl. Cryst. (1979), 12, 39–41] applied to a small number of data (less than ten) and adapted for interactive use. The verification of calculated solutions or even the trial-and-error search for the right solution is made by means of the visual comparison between the experimental diagram and simulated patterns displayed on a graphic screen. In addition, the rotation angles for setting the crystal to any new orientation may be computed.

First Time

Does humanity progress primarily through leaders organizing and directing followers, or through trial and error by individuals free to chart their own path? For most of human history ruling classes had the capacity and the desire to tightly regiment society, to the general detriment of progress. But beginning in the 1500s, Europeans developed a series of arguments for simply leaving well enough alone. First in the form of the scientific method, then in the form of free expression, and finally in the form of the continuously, spontaneously reordered free market, people began to accept that progress is hard, and requires that an immense number of mistakes be tolerated so that we may learn from them. This book tells the story of the development of these three ideas, and for the first time tells of the mutual influence among them. It outlines the rise, and dramatic triumph, of each of these self-regulating systems, followed by a surprising rise in skepticism, especially in the economic context. Such skepticism in the 20th century was frequently costly and sometimes catastrophic. Under the right conditions, which are more frequent than generally believed, self-regulating systems in which participants organize themselves are superior. We should accept their turbulence in exchange for the immense progress they generate.

Abstract A method for automated mask-layout and process synthesis for MEMS is presented. The synthesis problem is approached by use of a genetic algorithm. For a given desired device shape, and several fabrication process choices, this synthesis method will produce one or more mask-layouts and associated fabrication process sequences (which when used can generate shapes close to the desired one). Given complicated device shapes and wide range of fabrication process possibilities, the designer may encounter difficulty producing the right mask-layout and fabrication procedure by experience and trial and error. An automated synthesis tool like this will be helpful to the designer by increasing the efficiency and accuracy of the design of MEMS devices.

A safety device is proposed that will enable the operator of a sit-down rider forklift to discharge a self-dumping hopper while seated at the control station. Dumping proceeds without ground personnel which removes them from traffic flow and protects them from impacting loads that overspill the hopper, roll, bounce, or are accidentally discharged from the hopper. Just the right amount of rearward mast tilt is normally required to overcome the latching resistance of heavily loaded forward biased hoppers without becoming relatched when the trip lever is released. The associated trial and error balancing procedure is eliminated together with any need for muscling the latch rod. Unlatching poles are no longer used for elevated dumping.

This article focuses on a new amusement ride that blends several control systems by combining spinning-coaster thrills with interactive special effects. The Exterminator at Kennywood Amusement Park combines a ‘wild mouse’ coaster with the interactivity of a dark ride. ‘Dark ride’ is amusement maker parlance for fun house style frights that pop into view unexpectedly. A proximity sensor, positioned after the coaster and animation went in, begins the action sequence for this figure just as the riders come upon it. Bringing the Exterminator up to speed was a matter of controlling the coaster, controlling the animation, and controlling the interaction between the two independent systems. A process of trial and error, determining the right moment to start an event occurs only after the animation is in place and the carts are riding the rails. A double pneumatic fin brake below the track slows carts as needed before they enter the boiler.

‘Trial and Error (-related negativity)’ is a fascinating paper detailing the attempt to develop a new experimental paradigm to study the role of error-related negativity in the development of avoidance behavior. In my comments on this paper I will focus on the interaction between experimenters and participants as the former investigate various ways of designing the experiment, aiming to elicit the right kind of behavior from the participants. As in many psychological experiments, there is a fundamental tension here that experimenters must find a way to deal with: they must guide the subject to the proper performance, without the subject responding to the guidance as such. The performance must be natural, but within tight constraints. Recalcitrance or resistance of the subject must be prevented. Ultimately, the authors of ‘Trial and Error (-related negativity)’ failed in their attempt to do this. Their reflections on their failure are thorough and illuminating, but I will argue that they can be pushed slightly further.

Evidence Based Decision Making

In 1952, Lee Cronbach began identifying the fundamental challenges to conducting research in the real world with difficult-to-classify populations. He posited that “the highest function of research is to help us ask better questions in our next study” (Edwards & Cronbach, 1952, p. 59). Since that time, the fields of psychology, sociology, and education have struggled to identify the right questions to ask. This chapter suggests that the research community has fallen short of the mark because it continues to make one fatal flaw: It does not ask the practitioners who must implement research to guide us to the better questions. This chapter explores problems inherent in conducting research and suggests models that the new generation of researchers could explore to move from a trial-and-error design in the generation of research questions to a practitioner-prompted design. This discussion includes but is not limited to reflections on action research, implementation science, and practitioner-led research. This examination goes beyond the notion of evidence-based decision making to suggesting how research should be upended because the real needs of practitioners should provide the guidance for deciding what to study. Until we see such a paradigm shift, the resounding cry of “so what” will continue to be the response to the present “research from on high.”

The purpose of this study was to identify students' reasoning in generalizing the patterns that proved by generalizing the structural generalizations with involve the mathematical structures and empirical generalizations that emphasize perceptions or evidence derived from the found regularities. The subjects in this research were the 7th semester students of Mathematics Education of University of Madura, Indonesia. The research steps in this research were (1) giving the reasoning tests to the research subjects, (2) analyzing the results of reasoning tests to identify reasoning and mathematical proofs, (3) conducting in-depth interviews as the triangulation method, and (4) summarizing the tendencies of reasoning and proof of student in generalize pattern. Based on the results and discussion can be obtained that in the process of reasoning and verification, students in identifying the same pattern with trial and error, so by using trial and error students find many ways to generalize the existing pattern. However, sometimes through the use of ways of trial and error students find the right pattern. Therefore, the student only identifies a reasonable pattern and does not identify mathematical patterns, then makes reasonable assumptions about finding a relationship but only hypothetical and needs to prove the allegations and only do a few stages of reasoning and not doing the stages of proof, giving no argument and not doing a validation of the evidence.
