Occam's razor

Occam's razor
The sun, moon and other solar system planets can be described as revolving around the Earth. However that explanation's ideological and complex assumptions are completely unfounded compared to the modern consensus that all solar system planets revolve around the Sun. Ockham's razor (also written as Occam's razor and in Latin lex parsimoniae) is a principle of parsimony, economy, or succinctness used in problem-solving devised by William of Ockham (c. 1287 - 1347). It states that among competing hypotheses, the one with the fewest assumptions should be selected. Other, more complicated solutions may ultimately prove correct, but—in the absence of certainty—the fewer assumptions that are made, the better. Solomonoff's theory of inductive inference is a mathematically formalized Occam's Razor:[2][3][4][5][6][7] shorter computable theories have more weight when calculating the probability of the next observation, using all computable theories which perfectly describe previous observations.

Thought experiment A thought experiment or Gedankenexperiment (from German) considers some hypothesis, theory,[1] or principle for the purpose of thinking through its consequences. Given the structure of the experiment, it may or may not be possible to actually perform it, and if it can be performed, there need be no intention of any kind to actually perform the experiment in question. The common goal of a thought experiment is to explore the potential consequences of the principle in question: "A thought experiment is a device with which one performs an intentional, structured process of intellectual deliberation in order to speculate, within a specifiable problem domain, about potential consequents (or antecedents) for a designated antecedent (or consequent)" (Yeates, 2004, p. 150).

How to Turn Any Classroom Into a Makerspace There is a certain magic found in rolling up your sleeves and tackling a project head on, an undeniable sense of empowerment that results from solving problems and manifesting big ideas. In essence, that’s the soul of the maker movement — creative individuals from all walks of life united by an insatiable desire to improve the world around them. Although synonymous with 3D Printing, it extends far beyond a single technology or buzzword. Truth be told, the maker movement represents the instinctual drive of our species to ascend ever upwards: to innovate, design, and construct a better tomorrow.

Abductive reasoning Abductive reasoning (also called abduction,[1] abductive inference[2] or retroduction[3]) is a form of logical inference that goes from an observation to a hypothesis that accounts for the observation, ideally seeking to find the simplest and most likely explanation. In abductive reasoning, unlike in deductive reasoning, the premises do not guarantee the conclusion. One can understand abductive reasoning as "inference to the best explanation".[4] The fields of law,[5] computer science, and artificial intelligence research[6] renewed interest in the subject of abduction. Diagnostic expert systems frequently employ abduction. History[edit]

Believers vs non-believers "I’d shut down Apple" - Michael Dell, 1997. That line is from one of the most memorable quotes ever. Today Michael Dell said it was a misunderstood quote. Maybe, but my gut says it wasn’t. Why clarify it 14 years later. It doesn’t make any sense to me. How to Give Your Business Model a One-Two Punch - Jonathan Carson, Don Kellogg, Eddie Yoon by Jonathan Carson, Don Kellogg, Eddie Yoon | 12:17 PM April 24, 2012 It’s an intriguing hypothetical: In a fight between Bruce Lee and Mike Tyson, who wins? We’ll never know the answer to that question, but in today’s world of mixed martial arts (MMA), probably neither of them would have fared well. Meta-analysis In statistics, meta-analysis comprises statistical methods for contrasting and combining results from different studies, in the hope of identifying patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light in the context of multiple studies.[1] Meta-analysis can be thought of as "conducting research about previous research." In its simplest form, meta-analysis is done by identifying a common statistical measure that is shared between studies, such as effect size or p-value, and calculating a weighted average of that common measure. This weighting is usually related to the sample sizes of the individual studies, although it can also include other factors, such as study quality. The motivation of a meta-analysis is to aggregate information in order to achieve a higher statistical power for the measure of interest, as opposed to a less precise measure derived from a single study.

Why can’t the world’s greatest minds solve the mystery of consciousness? One spring morning in Tucson, Arizona, in 1994, an unknown philosopher named David Chalmers got up to give a talk on consciousness, by which he meant the feeling of being inside your head, looking out – or, to use the kind of language that might give a neuroscientist an aneurysm, of having a soul. Though he didn’t realise it at the time, the young Australian academic was about to ignite a war between philosophers and scientists, by drawing attention to a central mystery of human life – perhaps the central mystery of human life – and revealing how embarrassingly far they were from solving it. The scholars gathered at the University of Arizona – for what would later go down as a landmark conference on the subject – knew they were doing something edgy: in many quarters, consciousness was still taboo, too weird and new agey to take seriously, and some of the scientists in the audience were risking their reputations by attending. Such non-conscious humanoids don’t exist, of course.

Idealism The 20th-century British scientist Sir James Jeans wrote that "the Universe begins to look more like a great thought than like a great machine." Beginning with Immanuel Kant, German idealists such as G. W. Are you in a startup career path or are you one and done? Sometimes peoples' first startups are successful. More power to them. I've been pretty lucky, but not that lucky. In a startup career path, failure becomes experience for the next startup, which unfortunately will probably also fail. Repeat until success.
