The Bayes’ theorem describes the probability of an event, based on conditions that Might be related to the event. Bayes’ theorem can also be calculated as the Joint probability divided by the marginal.
Bayes’ theorem deals with conditional probability.

????(????) ∗ ????(????|????) = ????(????) ∗ ????(????|????)

????(????|????)=P(A)P(B|A)/P(B)

????(????|????)=P(Ai)P(B|Ai)/ P(A1)P(B|A1)+ P(A2)P(B|A2)

????(????|????)=P(Ai ∩B) / P(A1∩B)+P(A2∩B)

Perfect Yet/Already

Already se refiere a algo que ha pasado antes o más pronto de lo que se esperaba y es traducido como “ya” en español.

Yet es usado para algo que esperábamos que sucediera, pero todavía no ha pasado. Tendemos a usarlo en frases negativas e interrogativas. En frases negativas puede ser traducido como "aún" o "todavía" y en preguntas como "ya". En contraste con los otros adverbios de esta lección, "yet" va al final de la frase.

Qin Dynasty: Unification of China and Legacy

History2 KB

Qin Wangzheng was born in 259 BC, and it was the last year of the Eastern Zhou Dynasty. The Spring and Autumn Warring States began in 770 BC when Ping Wang moved to Luojing, ending in 221 BC before Qin Wang won the political unification of China, which lasted nearly 500 years.

The Qin dynasty is from 221 B.C to 206 B.C, the first emperor is Qin Shi Huang. The dynasty was short-lived. Qin Shihuang’s unification of China has done a lot of unprecedented achievements.

Second the country was abolished, and the county was established. It became the standard model for post-unification management...

Principles of Chemistry: From Stoichiometry to Molecular Orbital Theory

Chemistry4.48 KB

The Mole Concept

The mole concept is an International System unit of measurement for a substance. It is also represented by carbon-12, and 1 mole is equal to Avogadro's number (6.022 x 10^23).

The Periodic Table's Role in Stoichiometric Calculations

We use the periodic table to get values for given elements in a reaction to obtain their atomic values. We can then use these values for conversion from grams to moles or moles to grams in stoichiometric-based problems (gram/mole, mole-gram conversions).

Heat vs. Enthalpy

Heat is the energy that flows between a system and its surroundings due to a difference in temperature.

Enthalpy is equivalent to the total heat content of a system.

Why Only Enthalpy Explains Energy Associated with Chemical Bonds

Because...

Understanding Modern Science: Key Characteristics and Concepts

Specific Characteristics of Modern Science

Experimentation

Galileo Galilei introduced a significant shift in the scientific method by emphasizing the crucial role of observation and experimentation. Recognizing that certain hypotheses could not be observed in everyday life, he advocated for creating controlled "ideal situations" through experiments to confirm or refute them.

Mathematization

Galileo firmly believed that nature operates according to regularities that can be expressed using mathematical functions. This emphasis on mathematization became a cornerstone of modern science, contrasting with earlier approaches to physics. By quantifying reality, scientists could avoid the subjectivity and ambiguity inherent in everyday language.

Models of Explanation and Problems of the Hypothetical-Deductive Method

Philosophy and ethics4.8 KB

Models of Explanation

a) Deductive model
Type of explanation commonly found in the natural sciences and formal sciences, though not exclusively in those disciplines. It has the formal structure of a deductive argument in which the phenomenon that needs to be explained is a logically necessary consequence of the explanatory premises.
b) Probabilistic model
Usually encountered when the explanatory premises contain a statistical assumption about some class of elements. We have to resign ourselves to establishing the factors that have probably motivated or caused this event. This type of explanation is common in human sciences and also in Medicine.
c) Functional or teleological model
We have to resort to the intentions or the purpose for which someone
