Theorems of Pappus and Guldinus: Problem Solving01:12

Theorems of Pappus and Guldinus: Problem Solving

771
Pappus and Guldinus's theorems are powerful mathematical principles that are used for finding the surface area and volume of composite shapes. For example, consider a cylindrical storage tank with a conical top. Finding the surface area or volume can be challenging for such complex shapes. These theorems are particularly useful in calculating the volume and surface area of such systems. Here, the cylindrical storage tank with a conical top can be broken down into two simple shapes: a...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

3.2K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Contingency Table01:29

Contingency Table

2.5K
A contingency table provides a way of portraying data that can facilitate calculating probabilities. It is a method of displaying a frequency distribution as a table with rows and columns to show how two variables may be dependent (contingent) upon each other; The table helps determine conditional probabilities quite quickly and can help systematically organize, analyze and quantify data. The table displays sample values concerning two variables that may be dependent or contingent on one...

Deductive Reasoning01:16

Deductive Reasoning

55.8K
Deductive reasoning, or deduction, is the type of logic used in hypothesis-based science. In deductive reasoning, the pattern of thinking moves in the opposite direction as compared to inductive reasoning, which means that it uses a general principle or law to predict specific results. From those general principles, a scientist can deduce and predict the specific results that would be valid as long as the general principles are valid.
For example, a researcher can deduce specific predictions...

Castigliano's Theorem: Problem Solving01:14

Castigliano's Theorem: Problem Solving

699
The deflection of a simply supported beam that carries a central point load can be analyzed using structural mechanics principles, particularly by applying Castigliano's theorem. This theorem relates the displacement at the load application point to the partial derivatives of the strain energy in the structure. The simply supported beam with a point load at its center has symmetric reaction forces at the supports, each bearing half of the load. The bending moment at any point along the beam...

Hückel's Rule Diagram of π MOs: Frost Circle

4.5K
The Frost circle or the inscribed polygon method is a graphical method for determining the relative energies of π molecular orbitals (MOs) for planar, fully conjugated, and monocyclic compounds. This method was first described by A. A. Frost and Boris Musulin in 1953.
A Frost circle is constructed by drawing a polygon whose number of edges is equal to the number of carbons of the given cyclic system, with one of the vertices pointing down. Then, a circle is drawn enclosing the polygon so...

Area of Science:

  • Philosophy of Language
  • Cognitive Science
  • Formal Semantics

Background:

  • The possible worlds account of conditionals is influential but lacks experimental validation.
  • Existing theories struggle to explain human judgments on conditional statements.

Purpose of the Study:

  • To develop and validate a novel experimental task for testing possible worlds semantics of conditionals.
  • To investigate the empirical adequacy of Lewis and Stalnaker's possible worlds account for indicative and subjunctive conditionals.

Main Methods:

  • A novel experimental task was designed to elicit truth-value assignments for conditionals.
  • Three experiments were conducted, comparing competing truth tables and analyzing individual variation using Bayesian mixture models.
  • Results were tested against alternative hypotheses.

Main Results:

  • The possible worlds semantics of Lewis and Stalnaker successfully accounts for aggregate truth-value assignments.
  • This theory also explains the largest subgroup in the analysis of individual variation in truth assignments.
  • Results were replicated and alternative hypotheses were ruled out.

Conclusions:

  • The study provides novel experimental evidence supporting the possible worlds account of conditionals.
  • The findings demonstrate the empirical validity of this account for indicative conditionals at both aggregate and individual levels.
