Initially falling in love with rap through Wu-Tang Clan and The Roots, Logic began performing and recording as Psychological in 2009. For instance, 2 + 2 = 4 is true, 3-7 = 84.6 is false. He’s been known to solve a Rubik’s Cube while rapping.

LOGICWhat happens when logic goes wrong? Understanding how a computer “thinks” is one of the first steps to becoming an excellent computer programmer. A foundation in logic is crucial in developing this understanding. Mastering logic is more than learning a set of rules. It involves learning how to break problems into smaller chunks, figuring out how repeatable processes can save time and improve quality, and understanding how to organize problems into the right size.


The relatonship between mathematics and logic is rather complicated philosophical issue. To give a very short answer, the content of mathematics is restricted to abstract objects like numbers, functions, triangles, etc. But the principles and laws of logic are very general and are not restricted to such concepts.

The study of the principles of reasoning, especially of the structure of propositions as distinguished from their content and of method and validity in deductive reasoning. For the first time since this started on WP 2.3, I’ve rewritten how the core widget logic function works, so there may be ‘bumps ahead’.

For , & and xor a logical or raw vector. If involving a zero-length vector the result has length zero. Otherwise, the elements of shorter vectors are recycled as necessary (with a warning when they are recycled only fractionally). The rules for determining the attributes of the result are rather complicated. Most attributes are taken from the longer argument, the first if they are of the same length. Names will be copied from the first if it is the same length as the answer, otherwise from the second if that is. For time series, these operations are allowed only if the series are compatible, when the class and tsp attribute of whichever is a time series (the same, if both are) are used. For arrays (and an array result) the dimensions and dimnames are taken from first argument if it is an array, otherwise the second.

Aristotle’s work was regarded in classical times and from medieval times in Europe and the Middle East as the very picture of a fully worked out system. However, it was not alone: the Stoics proposed a system of propositional logic that was studied by medieval logicians. Also, the problem of multiple generality was recognized in medieval times. Nonetheless, problems with syllogistic logic were not seen as being in need of revolutionary solutions.

Armed with a greater appreciation of logic, axioms and mathematics, we will show some flaws in Western Philosophy, particularly in Immanuel Kant’s notion of a priori truths (Epilogue III). In a beautiful twist, the conception of mathematics provided will coincide with the ideas of ‘différance’ provided by Derrida (Epilogue IV). There’s also a connection between logic and determinism in Epilogue V.

It’s been a very different story at Redwood City, Calif.-based Sumo Logic, which has grown its headcount by 23 percent in 2019, according to LinkedIn, going from 594 employees in January to 731 employees this month. The SaaS machine data analytics company raised $110 million in a June round led by Battery Ventures, and has notched more than $100 million of annual revenue and a valuation of $1 billion.

Formal logic is also known as symbolic logic or mathematical logic. It forms part of mathematics, and is often considered the foundational discipline upon which the rest of mathematics can be built. US Logic can provide a single source, vendor neutral services program for your Data Center.

Middle English, from Old French logique, from Latin logica, from Greek logikē (tekhnē), (art) of reasoning, logic, feminine of logikos, of reasoning, from logos, reason; see leg- in the Appendix of Indo-European roots.

Rapper Logic performed his hit song “1-800-273-8255” on the Grammys stage, featuring singers Alessia Cara and Khalid, in an emotional and political performance. But what many might not know is this important reason behind the song’s lengthy title.

Since v50 the widget logic code runs such that when dynamic_sidebar is called in a theme’s code it will ‘return false’ if no widgets are present. In such cases many themes are coded to put in some default sidebar text in place of widgets, which is what you are seeing.

One thing you should note about this definition is that logic is concerned with the principles of correct reasoning. Studying the correct principles of reasoning is not the same as studying the psychology of reasoning. Logic is the former discipline, and it tells us how we ought to reason if we want to reason correctly. Whether people actually follow these rules of correct reasoning is an empirical matter, something that is not the concern of logic.

This is called showing the logical form of the argument. It is necessary because indicative sentences of ordinary language show a considerable variety of form and complexity that makes their use in inference impractical. It requires, first, ignoring those grammatical features irrelevant to logic (such as gender and declension, if the argument is in Latin), replacing conjunctions irrelevant to logic (such as “but”) with logical conjunctions like “and” and replacing ambiguous, or alternative logical expressions (“any”, “every”, etc.) with expressions of a standard type (such as “all”, or the universal quantifier ∀).

isTRUE(x) is the same as is.logical(x) && length(x) == 1 && !(x) && x ; isFALSE() is defined analogously. Consequently, if(isTRUE(cond)) may be preferable to if(cond) because of NA s. In earlier R versions, isTRUE <- function(x) identical(x, TRUE), had the drawback to be false e.g., for x <- c(val = TRUE).

4. the system or principles of reasoning applicable to any branch of knowledge or study. I have a different stance on this topic. I think that there is no reasoning in logic, but there can be logic in reasoning.


The second class of paradoxes involves redundant premises, falsely suggesting that we know the succedent because of the antecedent: thus “if that man gets elected, granny will die” is materially true since granny is mortal, regardless of the man’s election prospects. Such sentences violate the Gricean maxim of relevance, and can be modelled by logics that reject the principle of monotonicity of entailment , such as relevance logic.


Philosophical logic deals with formal descriptions of ordinary, non-specialist (“natural”) language , that is strictly only about the arguments within philosophy’s other branches. Most philosophers assume that the bulk of everyday reasoning can be captured in logic if a method or methods to translate ordinary language into that logic can be found. Philosophical logic is essentially a continuation of the traditional discipline called “logic” before the invention of mathematical logic. Philosophical logic has a much greater concern with the connection between natural language and logic. As a result, philosophical logicians have contributed a great deal to the development of non-standard logics (e.g. free logics , tense logics ) as well as various extensions of classical logic (e.g. modal logics ) and non-standard semantics for such logics (e.g. Kripke ‘s supervaluationism in the semantics of logic).

The MC, singer, songwriter, and producer made his recording debut in 2009 and five years later hit the Top Five with his debut album, Under Pressure (2014), the first of several conceptual full-length projects to enter the Billboard 200 and rap charts within the upper reaches. Logic’s ascent continued through Everybody (2017); his third proper LP debuted at the top of multiple Billboard charts with weighty themes including mental health, exemplified by “1-800-273-8255,” a number two pop hit nominated for a Grammy award. Logic has since issued secondary volumes of his Bobby Tarantino and Young Sinatra series, the latter capped with YSIV (2018), and has published a novel, Supermarket (2019), with an accompanying rock-oriented soundtrack.

Logic has you thinking with reason and arguments (statements). Scientists use logic because it shows the relationships between the parts of an idea and the whole idea. Therefore, if you use logic, you can see a relationship between a few trees and the entire forest. On the other hand, if we talk about biology, if you understand how animals interact with each other then you are able to better understand the whole ecosystem.

Widget Logic” is open source software. The following people have contributed to this plugin. You can set up lots of paths, too. With a Multiple Choice question , you can create different paths for each answer. Logic Jump is very flexible, so you can be creative with it.

Science does involve logic, since we need logic to test our theories and check whether they are consistent. But for a theory to be a scientific one, it must either describe actual empirical facts about the world or the laws of nature in our universe. This is not the case with logic.

Logic Jump (available in Essentials and higher plans ) lets you create a typeform that responds to people’s answers. Respondents never have to skip irrelevant questions — because with Logic Jump, they’ll never even see them.

To overcome by logical argument. b. A mode of reasoning: By that logic, we should sell the company tomorrow. To apply logical reasoning to. In logic programming , a program consists of a set of axioms and rules. Logic programming systems such as Prolog compute the consequences of the axioms and rules in order to answer a query.

In a good deductive argument the truth of the premises absolutely guarantees the truth of the conclusion. Such an argument is valid It is literally impossible for the premises of a valid argument to be true while the conclusion is false. No matter what other facts crop up, the premises imply the conclusion, thus a valid argument is a good deal more powerful than a merely strong one. What you’re really after, though, is a sound argument: a sound argument combines validity with true premises. Since true premises guarantee a true conclusion in a valid argument, and the premises are true, the conclusion of a sound argument must be true as well.

Logic released The Incredible True Story” on Nov. 13. His second release with Def Jam, the sophomore album made it to No. 3 on the Billboard 200 albums chart. It was also Logic’s first album to hit No. 1 on both Billboard’s Rap and R&B Albums charts.

The performances of Maryland-bred motormouth MC Logic are the stuff of legend. He’s been known to solve a Rubik’s Cube while rapping. He’s been known to bring fans on stage to rap along. He’s been known to spit the lightning-fast verse immortalized on “100 Miles and Running” at ridiculous speeds. And, of course, he performs hits like “1-800-273-8255,” “Homicide,” “44 More” and “Everyday.” Logic manager Chris Zarou turned the MC from freestyling YouTube hopeful to nationally touring artist by the time of his headlining spot on the 2012 Visionary Music Group Tour. He’s done multiple treks since, including support on Kid Cudi’s The Cud Life tour in 2013, co-headlining with G-Eazy on The Endless Summer tour in 2016 and traveling on his own headlining jaunts.LOGIC
