말뭉치
- High among the notions that cause not a few students to wonder if perhaps math is not the subject for them, is mathematical proof.[1]
- Though it is the bedrock of professional pure mathematics, the concept of proof is barely touched on outside university mathematics departments.[1]
- For sure, I have never in my life seen a proof that truly fits the standard definition.[1]
- It’s not a bad approach if the goal is to give someone a general idea of what a proof is.[1]
- The notion of proof is central to mathematics yet it is one of the most difficult aspects of the subject to teach and master.[2]
- The remainder of the book delves further into different types of proof, including direct proof, proof using contrapositive, proof by contradiction, and mathematical induction.[2]
- We begin in this section by characterizing two somewhat extreme reactions to visual proofs, which we term the Baroque and Romantic reactions to visual proof.[3]
- One might rigidly insist, for example, that a proof must be expressed so as to explicitly draw logical connections between mathematical propositions.[3]
- Logic operates on the syntax of sentences, so without sentences there can be no proof write-up.[3]
- Something that doesn't address the general phenomenon can't be a proof that the phenomenon holds universally.[3]
- Although, at the time, some of his close collaborators said they found the proof to be correct, experts around the world struggled, often reluctantly, to slog through it, let alone verify it.[4]
- Classification of students’ proof schemes offers insights into students’ mathematical proving.[5]
- However, previous studies revealed little about finer progressions in students’ proving and barely examined their proof schemes involving counterexamples.[5]
- This study examined students’ proof schemes through their considerations of examples and counterexamples and reasoning in Proof Constructions.[5]
- The refined classifications revealed students’ progression through their sophisticated use of examples, counterexamples, and deductive inferences and that Proof Construction was knowledge-driven.[5]
- 29 , one of the oldest surviving fragments of Euclid's, a textbook used for millennia to teach proof-writing techniques.[6]
- A mathematical proof is an inferential argument for a mathematical statement , showing that the stated assumptions logically guarantee the conclusion.[6]
- Presenting many cases in which the statement holds is not enough for a proof, which must demonstrate that the statement is true in all possible cases.[6]
- Purely formal proofs , written fully in symbolic language without the involvement of natural language, are considered in proof theory .[6]
- The main conclusions suggest that the idea of addressing mathematical proof at all levels of school is a recent idea that is not yet fully implemented in schools.[7]
- Among the different functions of proof, the function of explanation deserves special attention due to the illumination and empowerment that it can bring to the students and their learning.[7]
- This article is concerned with shedding some light on Mathematics students' perceptions of mathematical proof, and how these perceptions may change over their first year at University.[8]
- "Proof" has been and remains one of the concepts which characterises mathematics.[9]
- The authors explore the principle techniques of direct and indirect proof including induction, existence and uniqueness proofs, proof by contradiction, constructive and non-constructive proofs, etc.[9]
- What is a proof that it yields understanding (when it does)?[10]
- But if that is right then we need to reconsider the notions of formal reasoning and formal proof.[10]
- In giving an informal proof, we try to cover the essential, unfamiliar, unobvious steps and omit the trivial and routine inferences".[10]
- But what exactly is the relationship between the mathematician's reasoning and the formalized proof?[10]
- That’s one reason mathematicians strive for proof, not just evidence.[11]
- It’s proof that establishes mathematical truth.[11]
- The twin primes conjecture is one example where evidence, as much as proof, guides our mathematical thinking.[11]
- A proof by construction is just that, we want to prove something by showing how it can come to be.[12]
- This book describes the language used in a mathematical proof and also the different types of proofs used in math.[13]
- According to Hardy (1999, pp. 15-16), "all physicists, and a good many quite respectable mathematicians, are contemptuous about proof.[14]
- There is some debate among mathematicians as to just what constitutes a proof.[14]
- The four-color theorem is an example of this debate, since its "proof" relies on an exhaustive computer testing of many individual cases which cannot be verified "by hand.[14]
- A page of proof-related humor is maintained by Chalmers.[14]
- Moreover, we suggest that the different institutional meanings of proof might help to explain this difficulty.[15]
- University of Maryland mathematicians Jacob Bedrossian, Samuel Punshon-Smith and Alex Blumenthal have developed the first rigorous mathematical proof explaining a fundamental law of turbulence.[16]
- "We believe our proof provides the foundation for understanding why Batchelor's law, a key law of turbulence, is true in a way that no theoretical physics work has done so far.[16]
- A mathematical proof of the law can be considered as an ideal consistency check.[16]
- "Sometimes the method of proof can be even more important than the proof itself.[16]
- This, in turn, has motivated a search for alternative accounts of mathematical proof purporting to be more faithful to the reality of mathematical practice.[17]
- This dramatic shift allows the constructive, elementary definition of the syntax of theories and, in particular, of the concept of proof in a formal theory.[18]
- Meaningful mathematics is to be based, Bernays demands, on primitive intuitive knowledge that includes, however, induction concerning natural numbers—both as a proof and definition principle.[18]
- Bernays concludes the outline by suggesting, “This would be followed by the development of proof theory”.[18]
- The third part of these lectures is entitled The grounding of the consistency of arithmetic by Hilbert’s new proof theory.[18]
- If the proof of a theorem is not immediately apparent, it may be because you are trying the wrong approach.[19]
- A proof is defined as a derivation of one proposition from another.[20]
- A finest proof of this kind I discovered in a book by I. Stewart.[20]
- This radical, profoundly scholarly book explores the purposes and nature of proof in a range of historical settings.[21]
- Together, Karine Chemla and her ensemble of scholars successfully make the case for revising the nineteenth-century portrait of the history of mathematical proof that prevails even today.[21]
