A physical paradox typically refers to a situation or concept in physics that appears to contradict established theories or intuitive understanding but nonetheless provokes further inquiry or insight into the nature of physical reality. These paradoxes often highlight gaps in our understanding or the limitations of our theoretical frameworks. Some famous examples of physical paradoxes include: 1. **Zeno's Paradoxes**: A series of philosophical problems that challenge our understanding of motion and divisibility.
In physics, time is a fundamental concept that allows us to quantify the duration of events and the intervals between them. It is often considered a fourth dimension, alongside the three spatial dimensions of length, width, and height. Here are several key aspects of time in physics: 1. **Measurement**: Time is measured in various units, with the second being the SI (International System of Units) base unit. Other common units include minutes, hours, and days.
"The Doors of Perception" is a philosophical work by Aldous Huxley, published in 1954. The book details Huxley's experiences with the psychedelic substance mescaline, which he ingested in order to explore the nature of human consciousness and perception. The title of the book references a quotation from the poet William Blake, who wrote, "If the doors of perception were cleansed, everything would appear to man as it is, infinite.
Theoretical physics is a branch of physics that employs mathematical models and abstractions to explain, predict, and understand physical phenomena. It aims to develop conceptual frameworks that describe the laws of nature and the behavior of the physical universe, often focusing on fundamental aspects of reality that can be difficult to observe directly.
Subjective experience refers to the individual's personal, internal perception of events, feelings, and thoughts. It encompasses the way a person interprets and interacts with the world based on their unique consciousness, emotions, memories, and interpretations. This concept is central to philosophy of mind, psychology, and cognitive sciences, as it addresses how subjective experiences influence and shape one's understanding of reality.
Transcendental apperception is a concept primarily associated with the philosophy of Immanuel Kant. It refers to the self-awareness or the consciousness of the self that is essential for the unity of experience. For Kant, apperception is the process by which the mind recognizes its own acts of cognition and relates them to a unified self. In Kant's framework, transcendental apperception is a necessary condition for experiencing the world as a coherent whole.
Clinical pluralism is an approach in healthcare that recognizes and integrates multiple methods, perspectives, and practices in the diagnosis, treatment, and management of health conditions. This concept advocates for the use of various therapeutic modalities from different medical paradigms, including conventional medicine, complementary and alternative medicine, and other health practices that may not conform to the dominant biomedical model.
Interaction-free measurement is a quantum phenomenon that allows the determination of the presence of an object without the direct interaction that would normally occur in a conventional measurement. This concept is most famously illustrated by the "Elitzur-Vaidman bomb tester" thought experiment. In a classical measurement scenario, when a measurement is made on a system, an observer typically interacts with that system, which can alter its state.
Quantum foundations is a field of research that seeks to understand the conceptual and philosophical underpinnings of quantum mechanics. It addresses fundamental questions about the nature of reality, measurement, and the role of observers in quantum systems. This area of study aims to clarify the interpretation of quantum mechanics, exploring topics such as: 1. **Measurement Problem**: Understanding how and why observations lead to definite outcomes in quantum systems, and what this implies for the nature of reality.
Phenomenology in psychology is a qualitative research approach that focuses on exploring and understanding the subjective experiences of individuals. Originating from the philosophical movement founded by Edmund Husserl in the early 20th century, phenomenology seeks to understand how people perceive, interpret, and make sense of their experiences. In psychology, phenomenological methods are used to gather in-depth insights into people's thoughts, feelings, and behaviors. This approach emphasizes the importance of context and the personal meaning that individuals assign to their experiences.
"A General View of Positivism" is a philosophical work written by Auguste Comte, a French philosopher regarded as the founder of positivism. Published in the 19th century, this work outlines Comte's ideas about the development of human knowledge and society, advocating for a scientific approach to understanding the world.
"Absolute theory" can refer to different concepts depending on the context in which it is used, such as philosophy, physics, or ethics. Here are a few interpretations: 1. **Philosophy**: In metaphysics, "absolute theory" can relate to the concept of an ultimate reality or absolute being that underpins existence.
"Dialogo de Cecco di Ronchitti da Bruzene in perpuosito de la stella Nuova" is a literary work by the Italian poet and philosopher Giovanni Boccaccio, written in 1476. The title translates to "Dialogue of Cecco di Ronchitti from Bruzene on the New Star," and it is a dialogue that discusses the appearance of a new star that was observed in the sky.
"Foundations of the Science of Knowledge" is a philosophical work by the German philosopher Johann Gottlieb Fichte, published in 1794. The title in German is "Grundlage der gesamten Wissenschaftslehre." This work is significant within the context of German Idealism and serves as a critical moment in the development of modern philosophy. In this text, Fichte presents his ideas on the nature of knowledge, the self, and the relationship between the individual and the external world.
"Researchers of photosynthesis" refers to scientists who study the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen. This process is fundamental to life on Earth, as it provides the primary energy source for nearly all ecosystems and is critical for the carbon cycle.
Scientistic materialism is a philosophical stance that combines elements of scientism and materialism. Here’s a breakdown of the two components: 1. **Scientism**: This is the belief that the methods of the natural sciences are the most authoritative or the only legitimate way to acquire knowledge about the world.
A list of notable photochemists would include scientists who have made significant contributions to the field of photochemistry, the study of chemical reactions and processes that occur as a result of light energy absorption. While a comprehensive list would be extensive, here are some prominent photochemists known for their impactful work: 1. **Robert H. Grubbs** - Known for his research in catalysis and for developing methodologies in organic synthesis, including photoinitiated reactions. 2. **Richard H.
John William Draper (1811–1882) was an English-American scientist, philosopher, physician, and photographer, recognized for his significant contributions to various fields, including chemistry, photography, and astronomy. He is best known for his work in promoting the use of photography in scientific documentation and is often credited with creating some of the first photographs of the Moon in the 1840s.
Nicholas Turro is a prominent American chemist known for his contributions to the fields of organic chemistry and photochemistry. He is particularly recognized for his work on the principles of chemical reactions that are initiated or controlled by light. Turro has published extensively in scientific journals and has been influential in advancing the understanding of excited-state chemistry and the use of photonic processes in various applications. In addition to his research, he has also been involved in teaching and mentoring students in chemistry.
Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting photographic images. It plays a crucial role in fields such as mapping, surveying, architecture, archaeology, and remote sensing. Journals dedicated to photogrammetry typically publish research articles, reviews, case studies, and technical papers on various aspects of the discipline.

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.
