Philosophy of language is a subfield of philosophy that explores the nature, origins, and use of language. It examines fundamental questions about meaning, reference, truth, and the relationship between language and reality. Key topics in this area include: 1. **Meaning**: What does it mean for words or sentences to have meaning?

The philosophy of mind is a branch of philosophy that explores the nature of the mind, consciousness, and their relationship to the physical body, particularly the brain. It addresses fundamental questions related to consciousness, mental states, the nature of thought, perception, emotion, and the relationship between the mind and the body (often referred to as the mind-body problem).

Abstract object theory is a philosophical framework that deals with the nature of abstract objects—entities that do not exist in physical space and do not possess physical properties. Examples of abstract objects include numbers, properties, concepts, sets, and other non-material entities. The theory explores questions such as: 1. **Existence**: What does it mean for an abstract object to exist? Unlike physical objects, abstract objects are often seen as not having a location in space or time.

Ballistics is the science that studies the motion, behavior, and effects of projectiles, most commonly firearms and ammunition. It encompasses several specific areas: 1. **Internal Ballistics**: This involves the processes that occur inside the firearm from the moment the cartridge is fired until the projectile exits the barrel. It examines factors like the combustion of gunpowder, pressure build-up, and the mechanics of the firearm's action.

Materials science is an interdisciplinary field that focuses on the properties, performance, processing, and applications of materials. It combines principles from physics, chemistry, engineering, and biology to understand how different materials behave under various conditions and how their internal structures influence their macroscopic properties. Key aspects of materials science include: 1. **Understanding Material Properties**: This involves studying mechanical, thermal, electrical, optical, and magnetic properties of materials. Scientists use these properties to determine how materials will perform in different applications.

Mechanical engineering is a branch of engineering that involves the design, analysis, manufacturing, and maintenance of mechanical systems. It combines principles of physics, mathematics, material science, and engineering principles to solve problems related to mechanical systems and processes. Mechanical engineers work on a wide range of applications, including but not limited to: 1. **Thermodynamics:** Studying the behavior of heat and energy transfer in systems, applicable in engines, HVAC systems, and refrigeration.

Applied geometry is a branch of geometry that focuses on the practical application of geometric principles and methods to solve real-world problems. It encompasses various fields and combines geometric concepts with tools from mathematics, engineering, computer science, and other disciplines. Some key areas where applied geometry plays an important role include: 1. **Computer Graphics**: Used extensively in rendering images, animations, and visual effects through modeling shapes, transformations, and perspective.

Mathematical finance is a field of applied mathematics that focuses on the mathematical modeling and analysis of financial markets and instruments. It integrates concepts from probability theory, statistics, differential equations, and stochastic calculus to understand and manage financial risks and to price financial derivatives. Key areas of mathematical finance include: 1. **Option Pricing**: Developing models to determine the fair value of options and other derivatives. The Black-Scholes model is one of the most famous examples.

Crazy overlaps with Ciro Santilli's OurBigBook Project, Wikipedia states:

In the 2020's, this refers to writing down everything you know, usually in some graph structured way.

This is somewhat the centerpiece of Ciro Santilli's documentation superpowers: dumping your brain into text form, which he has been doing through Ciro Santilli's website.

This is also the closest one can get to immortality pre full blown transhumanism.

Ciro's still looking for the restore this plaintext backup on a new body though.

It is a good question, how much of your knowledge you would be able to give to others with text and images. It is likely almost all of it, except for coordination/signal processing tasks.

His passion for braindumping like this is a big motivation behind Ciro Santilli's OurBigBook.com work.
