What's the difference between conjecture and theorem?

Conjecture


Definition:

  • (n.) An opinion, or judgment, formed on defective or presumptive evidence; probable inference; surmise; guess; suspicion.
  • (v. t.) To arrive at by conjecture; to infer on slight evidence; to surmise; to guess; to form, at random, opinions concerning.
  • (v. i.) To make conjectures; to surmise; to guess; to infer; to form an opinion; to imagine.

Example Sentences:

  • (5) However, the mechanism by which this tolerance develops is currently a matter of conjecture.
  • (6) A quote from Peter Greste originally stated: "… we have spent three months in prison based on substantiated allegations and conjecture …".
  • (7) This conjecture was, however, not supported by analyses that considered the positive control compound and a pure chemical as possible reference assays.
  • (8) We consider two mechanisms to obviate the diffusion limitation problem, and conjecture that at high substrate concentration, H(2)CO(3) reaches the active site by collision with the enzyme molecule, and subsequent surface diffusion to the active site.
  • (9) It is conjectured that these behavioral qualities may be universal for emotionally healthy individuals and that future research with larger samples may bear this out.
  • (10) Such specific binding of parasite proteins to immobilised Band-3 supports recent conjecture as to its role as a host receptor during parasite invasion.
  • (11) I examine the conjecture that the signal for this regulation is the ratio of uncharged tRNA to aminoacyl-tRNA, that this signal controls the concentration of guanosine tetraphosphate, and that the concentration of guanosine tetraphosphate controls transcription of rrn genes.
  • (12) However, the idiotype expression was not simply related to total immunoglobulin levels and the controlling mechanisms of idiotype expression on different isotypes remain a matter of conjecture.
  • (13) If the positions of the principal points of the crystalline lens are conjectured, its equivalent power and that of the eye can be calculated as described from ocular dioptrics.

  • (16) Alternative explanations for its effectiveness remain conjectural.
  • (17) Since, in equal concentrations, menthol specifically impairs neuronal calcium currents, the results are consistent with the conjecture that in cold receptors, menthol reduces the activation of a calcium-stimulated outward current by an impeding effect on a calcium conductance, thereby inducing depolarization and a modification of bursting behavior.
  • (18) We conjecture that the efficacy of radioimmunoconjugates against responsive cell types may be the result of passive DNA damage by ionizing radiation and the initiation of apoptosis in response to radioimmunotherapy.
  • (19) But the fact that the ability to create new explanations is the unique, morally and intellectually significant functionality of "people" (humans and AGIs), and that they achieve this functionality by conjecture and criticism, changes everything.
  • (20) Since nafenopin pretreatment stimulates the synthesis of new liver tissue, it is presently a matter of conjecture as to whether or not the newly formed hepatocytes have the capacity to take up and excrete BP and its metabolites or whether nafenopin inhibits transport in all liver tissue.

Theorem


Definition:

  • (n.) That which is considered and established as a principle; hence, sometimes, a rule.
  • (n.) A statement of a principle to be demonstrated.
  • (v. t.) To formulate into a theorem.

Example Sentences:

  • (1) The operational meaning of all the resulting theorems is that when any of them appear to be refuted experimentally, the presence of more than one parallel transport pathway (that is, of membrane heterogeneity transverse to the direction of transport) can be inferred and analyzed.
  • (2) From these, the upper limits of visual acuity were derived on the basis of the assumptions of the sampling theorem.
  • (3) We reviewed the literature on the performance of the blood culture as a diagnostic test and analyzed the data with Bayes' theorem to find the optimal number of cultures to draw.
  • (4) Based upon the sensitivity and specificity, the authors calculated the expected predictive values for different groups of asymptomatic individuals using Bayes' theorem.
  • (5) The prognostic relevances of the characters investigated were tested by Bayes' theorem.
  • (6) The structure of nonverbal communication expressed as eye-contact between two human beings is analyzed using graph-theoretic tools involving a theorem of König on bipartite graphs and various results concerning directed graphs (as in Harary).
  • (7) Based on Bayes' theorem, 'Solubile' uses up to 47 items of information about the patient to produce the most probable diagnosis from 22 possible diseases.
  • (8) Using Monte Carlo methods, we verify an equation derived from O'Connor's scaling theorem relating scatter-primary ratios at small depths and field sizes to those at larger depths and fields.
  • (9) We have extended their work, which is based on logit analysis, to consider, using Bayes' theorem, the influence of the proportion of carcinogens upon the decision rules for declaring a battery result positive or negative.
  • (10) The introduction of this differentiation of histopathologic diagnoses is not just another sophisticated scientific theorem; its practical significance may be seen in a definitive restriction of the application of antirejection therapy, which means a reduction of the risks and side effects imposed on heart-transplanted patients by chemotherapy and particularly by steroid therapy.
  • (11) A theorem about correspondence of the graph constructed and coefficients of the characteristic polynomial of linearized kinetic equations is proved.
  • (12) One depends on solving a set of non-linear simultaneous equations, and the other on Taylor's theorem.
  • (13) It is based on three steps: 1) the search for all possible helical regions relied on a mathematical approach derived from the convolution theorem; it uses a tetradimensional complex vector representation of the bases along the sequence; 2) a 'tree' search for a set of minimum free energy structures, by the aid of an approximate energy evaluation to reduce the computer time requirements; 3) the exact calculation and refinement of the energies.
  • (14) The power is either derived from the Pythagorean Theorem or measured on graph paper.
  • (15) The steady-state solutions (Kirchhoff-Hill theorem) yield expressions for the relationship between the small signal conductance of univalent ions and the concentration of these ions in the external bathing medium (a saturation curve) and for the ionic currents and the steady-state current-voltage curve (N-shaped).
  • (16) In this situation the general principles of decision analysis can be contemplated: the characteristics of the test (sensibility and specificity), the prevalence of the disease and Bayes theorem and the concept of utility.
  • (17) These assumptions are not universally true and it is shown that the theorems can be modified to take account of such deviations.
  • (18) Using Bayes theorem and logistic regression analysis, the effect of changing driver characteristics on the probability of a fatality was explored.
