In the context of electrical engineering and physics, the terms "power," "root power," and "field quantities" have specific meanings. Here’s an overview of each: ### Power Power is defined as the rate at which energy is transferred, converted, or used. It is measured in watts (W) in the International System of Units (SI).

A "toy model" is a simplified representation of a complex system or phenomenon used to gain insights, test hypotheses, or illustrate concepts. These models are typically characterized by their abstraction and reduction of real-world complexities, allowing researchers and scientists to focus on specific features or behaviors without the distractions of extraneous details. Toy models are commonly used in various fields such as physics, economics, biology, and computer science.

Univariate refers to involving or consisting of a single variable. It is a term commonly used in statistics, data analysis, and machine learning to describe data, analysis, or models that focus on just one variable at a time.

"Without loss of generality" (often abbreviated as WLOG) is a phrase commonly used in mathematical proofs and reasoning. It indicates that a certain assumption can be made without affecting the generality of the argument or conclusion being presented. In other words, focusing on a specific case or example is permissible because the logic or outcome will hold true for other similar cases.

The Comparison Theorem is a fundamental result in real analysis, particularly in the study of improper integrals and series. It is often used to determine the convergence or divergence of a given integral or series by comparing it to another integral or series whose convergence is known. There are two main contexts in which the Comparison Theorem is applied: for integrals and for series.

The Laplace transform is a powerful integral transform used in various fields, especially in engineering and differential equations. It transforms a function of time (usually denoted as \( f(t) \)) into a function of a complex variable \( s \). Here is a list of some common Laplace transforms: 1. **Unit Step Function**: \[ \mathcal{L}\{u(t)\} = \frac{1}{s} \] 2.

The classification of complex surfaces is a rich area in algebraic geometry. A complex surface is a two-dimensional complex manifold, which can be studied both from the perspective of complex geometry and algebraic geometry. ### Types of Complex Surfaces Complex surfaces can be classified based on their geometric and algebraic properties. Here’s a list of important types of complex surfaces along with some examples: 1. **Algebraic Surfaces**: These surfaces can be defined by polynomial equations in projective space.

A list of tessellations refers to various patterns or arrangements that fill a plane without any gaps or overlaps. In mathematics and art, tessellations are studied for their geometric properties and aesthetic appeal. Here are some common types of tessellations: 1. **Regular Tessellations**: These are formed using a single type of regular polygon.

Nonlinear ordinary differential equations (ODEs) are differential equations that are not linear in the unknown function and its derivatives. The list of nonlinear ODEs can encompass a wide variety of forms and classifications. Here are some common types and examples of nonlinear ODEs: ### 1.

The study of partial differential equations (PDEs) encompasses a wide array of topics, which can be organized into several categories. Below is a list of topics often encountered in the study of PDEs: ### 1. **Basic Concepts** - Definition of PDEs - Linear vs. Nonlinear PDEs - Order of PDEs - Classification of PDEs (elliptic, parabolic, hyperbolic) ### 2.

A list of polygons typically refers to a classification or enumeration of different types of polygons based on their number of sides and other characteristics.

Set theory is a branch of mathematical logic that deals with sets, which are collections of objects. Below is a list of topics commonly studied in set theory: 1. **Basic Definitions** - Sets, Elements, and Notation - Empty Set (Null Set) - Universal Set - Subsets - Proper Subsets 2.

You need separate accounts for different countries: money.stackexchange.com/questions/73361/two-banks-in-two-countries-is-it-possible-to-have-a-unique-paypal-account it's a pain.

This is a good company, first they truly helped reduce international transfer fees. They they continued to morph into a decent challenger bank.

Their Wise Interest account was amazing as of late 2023: wise.com/gb/interest/

Instant access with representative national interests and 0.29% fees.

Brick and mortar banks were way way behind in that regard!

E.g. October 2023, Wise was doing 4.87% interest after fees, while Barclay's best option was 1.16% above 5k pounds on the Rainy Day Saver (5% below). Ridiculous!

Update: On November 2023 unfortunately they more than doubled their fees from 0.19% to 0.46%:but it still was a good option to keep cash in.
