Preformationism is a historical biological theory that existed before the discovery of modern genetics. It posited that organisms develop from pre-existing miniature versions of themselves, known as "homunculi." According to this view, all the traits of an organism were thought to be fully formed at the time of fertilization or were contained in the sperm or egg, and development was merely a process of growth and unfolding, rather than a process of complex development and differentiation from simpler forms.
Predictive power refers to the ability of a model or tool to accurately forecast future outcomes based on past and present data. In various fields such as statistics, machine learning, finance, and social sciences, predictive power is a crucial measure of how well a model can predict unknown data points. Key aspects of predictive power include: 1. **Accuracy**: The degree to which predictions made by the model match actual outcomes.
Postnormal times is a concept introduced by philosopher Ziauddin Sardar to describe a period characterized by uncertainty, complexity, and rapid change, often as a result of advancements in technology, globalization, and shifting societal norms. The term suggests that traditional ways of thinking and understanding the world are no longer adequate for navigating contemporary challenges. In postnormal times, factors such as unpredictability and the inadequacy of existing models influence decision-making processes.
Post-normal science is a concept that arises in response to the limitations of traditional scientific methods when addressing complex, uncertain, and contested issues, particularly those that have significant societal implications. The term was coined by Silvio Funtowicz and Jerome Ravetz in the mid-1990s. Post-normal science emphasizes the importance of including a wider range of stakeholders in the scientific process, recognizing that in situations of high uncertainty and high stakes, traditional models of scientific inquiry may not be sufficient.
Positivism is a philosophical theory and approach that emphasizes the importance of observable phenomena and empirical evidence in the acquisition of knowledge. It originated in the early 19th century, primarily associated with the work of French philosopher Auguste Comte, who is often considered the father of positivism. Key features of positivism include: 1. **Empiricism**: Knowledge should be derived from sensory experience and empirical observation rather than speculation or metaphysics.
Planck's principle, often associated with Max Planck's work in theoretical physics, refers to the fundamental idea of quantization of energy. Planck introduced the concept of energy quanta in 1900 to explain black-body radiation, leading to the development of quantum theory. The key aspects of Planck's principle include: 1. **Quantization of Energy**: According to Planck, energy is not continuous but rather exists in discrete packets called "quanta.
"Physics envy" is a term often used in the social sciences and humanities to describe a phenomenon where scholars in these fields seek to adopt the methods, standards, and rigor of the natural sciences, particularly physics. This term expresses a certain admiration for the perceived precision, objectivity, and empirical validation found in physics, which some practitioners of the social sciences feel is lacking in their own disciplines.
Aristotle's concept of physics, as articulated in his works such as "Physics" (or "Physica"), encompasses a broad exploration of the natural world and fundamental principles governing it. While modern physics is a highly specialized field involving mathematics and empirical testing, Aristotle's approach was more philosophical and observational.
Physicalism is a philosophical theory that asserts that everything that exists is ultimately physical in nature, or can be understood in terms of physical processes and entities. It holds that all phenomena, including mental states, consciousness, and abstract concepts, can be explained by physical laws and interactions, and that there is nothing beyond the physical realm. There are several key aspects to physicalism: 1. **Reductionism:** Physicalism often involves the idea that higher-level phenomena can be reduced to lower-level physical facts.
The philosophy of psychiatry is a subfield of philosophy that explores the fundamental concepts, methods, and implications of psychiatry as a discipline. It examines the philosophical issues surrounding mental health, mental illness, and the practices involved in psychiatric diagnosis and treatment. This area of study raises several important questions, including: 1. **Nature of Mental Illness**: What constitutes mental illness? How do we differentiate between normal variations in behavior and pathology? What is the relationship between mental illness and brain function?
Philosophy of physics is a subfield of philosophy that explores the foundational, conceptual, and interpretative issues arising in the field of physics. It examines the implications of physical theories and phenomena, as well as the philosophical underpinnings of the methods and assumptions employed in physics. Key areas of inquiry within philosophy of physics include: 1. **Nature of Space and Time**: Philosophers investigate the nature of space and time as described by various physical theories, particularly in the framework of relativity.
The philosophy of motion delves into the conceptual, metaphysical, and epistemological questions surrounding the nature of motion and change. It addresses several key issues: 1. **Nature of Motion**: What is motion? Is it a fundamental aspect of reality, or is it merely an illusion or a construct? Philosophers have debated whether motion is a property of objects themselves or a relationship between them. 2. **Time and Space**: Motion is often intimately connected to the concepts of time and space.
The philosophy of chemistry is a subfield of the philosophy of science that specifically addresses the foundational, conceptual, and methodological issues related to the discipline of chemistry. It explores questions concerning the nature of chemical substances, the principles and theories that govern chemical interactions, the relationship between chemistry and other sciences (particularly physics), and the interpretation of chemical knowledge. Here are some key themes within the philosophy of chemistry: 1. **Ontology of Chemical Substances**: This concerns questions about what chemical substances are.
The Philosophy of Science Association (PSA) is an organization that promotes scholarly research and discussion in the field of philosophy of science. It was founded in 1968 to foster communication and cooperation among those interested in philosophical issues related to the sciences. The PSA organizes conferences, publishes research, and supports educational initiatives in philosophy of science. The association serves as a platform for scholars to present their findings, engage in debates, and collaborate on projects.
Pessimistic induction is a philosophical argument primarily used in the philosophy of science to challenge the reliability of scientific theories. The core idea is that if we look at the history of science, we can see that many scientific theories that were once widely accepted have eventually been proven false. Based on this historical pattern, one might conclude that current scientific theories are also likely to be false or will eventually be overthrowed.
The Parable of the Sunfish is a story often used to illustrate a lesson about perspective, personal growth, and the importance of realizing one’s potential. While there are various versions and interpretations, the core message generally revolves around a fisherman who encounters a sunfish that is stuck, or unable to swim freely because it doesn’t recognize its own strength and capabilities. In one common interpretation, the sunfish is confined to a small area, believing it can only swim in limited circles.
Observation is the process of closely monitoring and examining something to gather information and gain insights. It involves using one's senses—sight, hearing, touch, taste, and smell—to detect and record details about an object, event, or phenomenon. In various contexts, observation can serve different purposes: 1. **Scientific Observation**: In scientific research, observation is used to collect data and test hypotheses. Scientists may conduct experiments or make field observations to study natural phenomena systematically.
Objectivity in science refers to the practice of making observations, conducting research, and drawing conclusions that are free from personal biases, emotions, or subjective influences. It emphasizes the importance of relying on empirical evidence and systematic methods, ensuring that findings can be verified and replicated by others. Key aspects of objectivity in science include: 1. **Empirical Evidence**: Science relies on observations and experiments that can be measured and quantified. Objective data is crucial for establishing facts and forming hypotheses.
"Not even wrong" is a phrase coined by physicist Wolfgang Pauli, often used to describe a theory or idea that is so far from reality or empirical evidence that it cannot even be classified as incorrect. Essentially, it implies that the argument or hypothesis is so misguided that it fails to meet the basic criteria for being considered a legitimate scientific theory; it's not just wrong, but fundamentally misguided.
Normative science refers to a branch of science that is concerned with establishing standards, norms, or values rather than purely descriptive or empirical observations. Unlike positive science, which focuses on what is and seeks to explain phenomena through objective data and facts, normative science addresses what ought to be, guiding behavior, policies, and ethical considerations.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
