Unified Modeling Language (UML) is a standardized modeling language used in software engineering to visualize, specify, construct, and document the artifacts of a software system. The applications of UML are broad and can be categorized into several areas: 1. **Software Design and Architecture**: - **Object-Oriented Design**: UML helps in designing software systems using object-oriented principles. Class diagrams, component diagrams, and package diagrams are used to represent the structure of a system.

David Harel is a prominent computer scientist known for his contributions to several areas in computer science, particularly in theoretical computer science, software engineering, and the design of programming languages. He is best known for his work on state machines, model checking, and formal methods. One of Harel's key contributions is the development of the Harel State Chart technique, which extends Finite State Machines and is widely used for modeling complex systems.

An inner class in Java is a class that is defined within the body of another class. It has access to the members (fields and methods) of the outer class, even if they are declared private. Inner classes can be used to logically group classes that are only used in one place, increasing the encapsulation and readability of the code. There are four types of inner classes in Java: 1. **Non-static Inner Class**: These are tied to an instance of the outer class.

PlantUML is an open-source tool used to create diagrams from plain text descriptions. It enables users to generate a variety of UML (Unified Modeling Language) diagrams, including class diagrams, sequence diagrams, use case diagrams, activity diagrams, component diagrams, state diagrams, and more. PlantUML's syntax is designed to be simple and intuitive, allowing users to write textual representations of diagrams that can then be rendered into graphical formats, such as PNG, SVG, or PDF.

A use case diagram is a visual representation of the interactions between users (or "actors") and a system to achieve specific goals. It is commonly used in software engineering and system design to help stakeholders understand the functional requirements of a system. Use case diagrams are part of the Unified Modeling Language (UML), which is a standardized modeling language in software engineering.

The Majorana equation is a relativistic wave equation that describes particles known as Majorana fermions. These particles are unique in that they are their own antiparticles, meaning that they possess the same quantum numbers as their antiparticles, unlike traditional fermions (like electrons), which have distinct antiparticles (such as positrons).

C-symmetry, also known as charge conjugation symmetry, refers to a fundamental symmetry in particle physics concerning the transformation of particles into their corresponding antiparticles. Specifically, it involves changing a particle into its antiparticle, which has the opposite electric charge and other quantum numbers. In terms of mathematical representation, charge conjugation transforms a particle state \(| \psi \rangle\) into its charge-conjugated state \(| \psi^C \rangle\).

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.

This is a good concept. For the ammount most people save, having a simple and easy to apply investment thesis is the best way to go.
