Millipede memory is a type of data storage technology that utilizes a unique approach to increase storage density. It is based on the concept of using a large number of tiny, nanoscale structures or "markers," which are reminiscent of the legs of a millipede, hence the name. These markers can represent data bits and can be read and written with high precision. The core idea behind millipede memory involves manipulating the physical properties of materials at the nanoscale.
Nanoneuroscience is an interdisciplinary field that combines principles from neuroscience, nanotechnology, and biophysics to study the nervous system and its components at the nanoscale. This area of research focuses on understanding the structure and function of neurons, glial cells, and synapses using advanced techniques and tools that operate at the nanometer scale (1 to 100 nanometers).
Nanotechnology in agriculture refers to the application of nanomaterials and nanoscale processes to enhance agricultural practices, improve crop yields, and promote sustainable farming. This interdisciplinary field merges principles from nanoscience, materials science, biology, and agriculture to develop innovative solutions that can address various agricultural challenges. Key applications of nanotechnology in agriculture include: 1. **Nanofertilizers**: These are fertilizers designed at the nanoscale, which can improve nutrient delivery to plants.
Nanotechnology in warfare refers to the application of nanoscience and nanotechnology to military systems and defense strategies. It involves the manipulation of matter at the atomic and molecular scale, typically at dimensions between 1 to 100 nanometers. The potential applications of nanotechnology in warfare are varied and can fundamentally change the nature of military operations.
Organ-on-a-chip is a technology that involves creating micro-engineered devices that mimic the functions and structures of human organs. These miniaturized systems integrate living cells and biomaterials in a way that simulates the physiological environment of an organ. The goal is to replicate specific organ systems to study biological processes, disease mechanisms, drug responses, and to optimize therapeutic strategies.
Scanning probe lithography (SPL) is a set of techniques used to create nanostructures on surfaces with high precision and resolution. It employs a scanning probe, which is a sharp tip or a small device that can manipulate materials at the nanometer scale. The key principle involves scanning a probe over a substrate to induce changes in materials, allowing for the fabrication of nanoscale patterns or structures.
Utility fog is a theoretical concept coined by researcher J. Storrs Hall in the early 1990s. It refers to a swarm of tiny autonomous robots, often imagined as nanobots or microscopic machines, that can work together to create a dynamic, shape-shifting mass of matter. This "fog" could be utilized for various purposes, such as altering its shape and texture to create objects, providing environmental control, or enabling new forms of interaction between humans and machines.
Crystal optics is a branch of optics that studies the interaction of light with crystalline materials. It deals with the unique properties of crystals that arise from their periodic atomic structure, which affects how light is transmitted, reflected, refracted, and polarized within and by the crystals. Key aspects of crystal optics include: 1. **Anisotropy**: Crystals are often anisotropic, meaning their optical properties vary depending on the direction of light propagation through the crystal.
Euhedral and anhedral are terms used to describe the crystal habits of minerals, specifically concerning the shape and development of their crystal faces. 1. **Euhedral**: This term describes crystals that have well-formed, clearly defined faces. Euhedral crystals grow in conditions that allow them to develop their natural geometric shapes without interference from neighboring crystals. As a result, these crystals have smooth surfaces and are typically more aesthetically pleasing and recognizable. Euhedral crystals are often considered ideal representations of a mineral species.
The term "geometry index" can refer to different concepts depending on the context. Here are a few possibilities: 1. **Geometric Index in Mathematics**: In a mathematical classification or representation of shapes, a geometric index could refer to a numerical value or a set of values that characterize certain properties of a geometric object. This might include measurements, ratios, or other metrics that help understand the properties of the shape, such as area, volume, or curvature.
A homologous series is a group of organic compounds that share a common structural formula and have similar chemical properties, yet differ from each other by a specific number of methylene groups (-CH₂-) or a similar repeating unit. The members of a homologous series exhibit a gradual change in physical properties, such as melting and boiling points, as the molecular weight increases.
The Patterson function is a mathematical construct used in the field of crystallography, particularly in the interpretation of X-ray diffraction data. It is named after the American physicist Alfred L. Patterson, who introduced the method. In crystallography, when X-rays are scattered by a crystal, the resulting diffraction pattern contains information about the electron density within the crystal structure. However, the phase information, which is crucial for determining the absolute positions of atoms, is lost in the Fourier transform that generates the diffraction pattern.
Protein crystallization is a laboratory technique used to form well-ordered crystals of proteins. This process is essential for studying the three-dimensional structures of proteins using X-ray crystallography, a powerful method for determining atomic arrangements in biological macromolecules. The main steps involved in protein crystallization typically include: 1. **Protein Purification**: Before crystallization, the protein of interest must be isolated and purified. This can involve techniques such as affinity chromatography, ion-exchange chromatography, and gel filtration.
The Sayre equation is a mathematical relation used in the context of X-ray crystallography, particularly in the study of macromolecular structures. It is named after the scientist who contributed to its formulation, Donald Sayre. The equation establishes a relationship between the structure factors of a crystal and the electron density within the crystal. Specifically, it relates the intensity of the diffracted X-rays to the electron density of the crystal lattice.
Streak seeding is a method used in agricultural production, particularly in the planting of crops like wheat, barley, and other grains. This technique involves sowing seeds in a pattern or "streak" rather than broadcasting them evenly across the field. The main goals of streak seeding are to improve seed-to-soil contact, enhance growth potential by optimizing light exposure, and facilitate better nutrient uptake by plants. In addition to its agronomic benefits, streak seeding can also have environmental advantages.
A Southwell plot is a graphical representation used primarily in the field of geotechnical engineering and soil mechanics to interpret the behavior of soil under loading conditions. It is particularly useful for analyzing the failure of soil structures, such as retaining walls or shallow foundations, and is often employed in the context of slope stability analysis. In a Southwell plot, the vertical axis typically represents the degree of movement or displacement of the soil structure, while the horizontal axis represents the load or pressure applied to the soil.
A supercell is a term used in crystallography to describe a larger periodic unit cell that is derived from a smaller, conventional unit cell of a crystal lattice. The supercell is constructed by repeating the basic unit cell in one or more directions, effectively creating a new, larger unit cell that can help researchers study the properties of materials with more complexity than the original unit cell can capture.
The Wigner-Seitz cell is a concept in solid-state physics and crystallography that is used to describe the local environment of atoms in a crystalline lattice. It is essentially a way to define a unit cell that encompasses the region around a lattice point, giving a clear representation of how space is partitioned among the particles in a crystal.

Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
