Accuracy, limits, and approximation01:28

Accuracy, limits, and approximation

1.4K
Accuracy, limits, and approximations are common in many fields, especially in engineering calculations. These concepts are imperative for ensuring that a given value is as close as possible to its true value.
Accuracy is defined as the closeness of the measured value to the true or actual value. In engineering mechanics, repeated measurements are taken during theoretical or experimental analyses to ensure that the result is precise and accurate.
The accuracy of any solution is based on the...

The Scientific Method02:40

The Scientific Method

57.1K
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

The Scientific Method01:32

The Scientific Method

220.0K
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

The Scientific Method

Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.

Revisionist Views of Adolescent and Adult Cognition

463
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Estimation of the Physical Quantities01:05

Estimation of the Physical Quantities

6.7K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

    Summary

    This study demonstrates that empirical progress can be linked to nomic truth approximation even with a weaker definition of nomic theories. The analysis applies when theories exclude conceptual possibilities, aligning with scientific common sense.

    Area of Science:

    • Philosophy of Science
    • Scientific Realism
    • Epistemology

    Background:

    • Previous work linked instrumentalist accounts of empirical progress to nomic truth approximation, assuming strong notions of nomic theories.
    • This assumption limited the applicability of the analysis to a specific, strong definition of scientific theories.

    Purpose of the Study:

    • To demonstrate that the analysis of empirical progress and nomic truth approximation applies under weaker assumptions about nomic theories.
    • To show that scientific common sense aligns with this less restrictive view of theories.

    Main Methods:

    • Analysis based on the concepts of truth content and falsity content of theories.
    • Examining the implications of nomic theories merely excluding certain conceptual possibilities as nomic possibilities.

    Main Results:

    • The previously established link between instrumentalism and nomic truth approximation holds even when nomic theories are understood more broadly.
    • The analysis is shown to be applicable when theories are defined by what they exclude (nomic possibilities) rather than a strong positive content.

    Conclusions:

    • A weaker, more common-sense notion of nomic theories is sufficient for relating instrumentalism to nomic truth approximation.
    • This broadens the scope of the truth approximation approach to empirical progress in the philosophy of science.
