Bought SM-SH56 cleat to accompany.
When it arrived, it felt a bit too long, around 2cm maybe free space after toe, and when I walk and the front part touches ground, heel comes off a bit, which is annoying. But I was too lazy to give it back and take the risk of a second try, also it felt correctly tight on sides. During first test ride it felt good.
It is slightly water proof. But if it rains a lot, it will get soaking wet. And once it does get wet, it feels like it is very very hard to dry, there don't seem to be any holes underneath.
Physical phenomena refer to observable events or occurrences in the natural world that are governed by the laws of physics. These phenomena can be categorized into various types based on their characteristics and the physical principles that describe them. Examples of physical phenomena include: 1. **Motion**: The movement of objects, including concepts like velocity, acceleration, and momentum. 2. **Forces**: Interactions that cause changes in motion, such as gravitational, electromagnetic, and nuclear forces.
A physical object is anything that has a tangible presence and occupies space. This means that it has specific dimensions (length, width, height), mass, and is made of matter, which can be solid, liquid, or gas. Physical objects can be perceived through our senses, particularly sight and touch.
Quantum non-equilibrium refers to the state of a quantum system that is not in thermodynamic equilibrium. In thermodynamics, systems at equilibrium exhibit well-defined macroscopic properties, such as temperature and pressure, and statistical distributions of their internal states (like the Boltzmann distribution). In contrast, non-equilibrium systems display time-dependent behavior and can have spatial gradients in quantities such as temperature, chemical potential, and density.
Historians of mathematics are scholars who study the development, context, and impact of mathematical ideas throughout history. This field, often referred to as the history of mathematics, involves examining ancient texts, manuscripts, and artifacts to understand how mathematical concepts, techniques, and practices evolved over time and how they influenced various cultures and societies.
The Antikythera mechanism is an ancient Greek analog device, believed to be one of the earliest known mechanical computers. It was discovered in a shipwreck off the coast of the Greek island Antikythera in 1901 and dates to around 150-100 BCE. The device is made up of a complex system of gears and is thought to have been used to calculate astronomical positions and predict celestial events, such as eclipses and the positions of the sun and moon.
"Gaṇita-sāra-saṅgraha" is a significant historical text in the field of mathematics, particularly in Indian mathematics. Written by the mathematician Bhāskara I in the 7th century CE, it serves as a concise compilation of various mathematical concepts and methods. The title translates to "Essence of Mathematics" or "Compendium of Mathematics." The work is primarily notable for its early treatment of arithmetic, algebra, and geometry.
The Hobbes-Wallis controversy refers to a philosophical and scientific debate from the 17th century that centered around the nature of mathematical truths and the existence of absolute space and time. This controversy primarily involved Thomas Hobbes, an English philosopher, and John Wallis, an English mathematician and theologian. The disagreement arose over several issues related to geometry and the nature of mathematical proofs. Hobbes was critical of the geometric methods employed by Wallis and other mathematicians of the time.
The Meissel–Mertens constant, often denoted as \( M \), is a mathematical constant that arises in number theory, particularly in the study of prime numbers and the distribution of primes.
In geometry, a chamfer is a beveled edge that is created on an object by cutting away a portion of the material at an angle, rather than leaving a sharp corner. This process helps to eliminate sharp edges, which can be a safety concern, and can improve the appearance of the object. Chamfers are commonly used in various fields, including manufacturing, carpentry, and design.
In logic and mathematics, "if and only if" is a biconditional statement that denotes a specific relationship between two propositions. It is typically abbreviated as "iff." A statement of the form "A if and only if B" means that: 1. If A is true, then B must also be true (AB). 2. If B is true, then A must also be true (BA).
A "mathemagician" is a term used to describe someone who combines mathematics with magic, often performing mathematical tricks and illusions that create a sense of wonder and surprise. This blend of mathematics and illusion is not only entertaining but can also be educational, making mathematical concepts more accessible and engaging for audiences. The term is often associated with mathematical entertainers like Arthur Benjamin, who is known for his performances that showcase rapid mental calculation and other mathematical feats in a theatrical and engaging manner.
A methodological advisor is a professional who provides guidance and support in the development and application of research methodologies within a specific field or study. Their role often involves: 1. **Designing Research Projects**: Assisting researchers in formulating clear and effective research questions and designing studies that appropriately address those questions. 2. **Selecting Methodologies**: Offering recommendations on suitable research methodologies, such as qualitative, quantitative, or mixed-method approaches, depending on the nature of the research.
The Brown measure is a concept from functional analysis and operator theory, specifically relating to the study of non-commutative probability and free probability. It provides a way to analyze certain types of operators, particularly those that are related to random matrices and free random variables. The Brown measure is defined for a normal operator \( T \) on a Hilbert space.
In mathematics, particularly in the contexts of algebra and number theory, "irreducibility" refers to the property of an object (often a polynomial) that cannot be factored into simpler components (factors) over a particular domain. The specific definition can vary based on the setting in which it is used.
Mathematical tables are organized sets of numerical values or functions arranged in a systematic manner, often used to simplify calculations in mathematics and related fields. They serve as reference tools that provide quick access to answers for various mathematical queries without the need for complex calculations.

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.
