The term "Turtle" in the context of robotics typically refers to the "Turtle graphics" system, which originated in the 1960s as a part of the Logo programming language. The Turtle is a small robot or virtual figure that can be controlled programmatically to move around a two-dimensional plane, drawing lines and shapes on the screen or on a surface. The idea was to teach programming concepts and encourage creativity in a visual and engaging way.

EDSAC 2, or the Electronic Delay Storage Automatic Calculator 2, was an early computer developed in the United Kingdom, specifically at the University of Cambridge. It was an evolution of the original EDSAC, which was one of the first stored-program computers, operational in 1949. EDSAC 2 was introduced in 1958 and featured several enhancements over its predecessor, including improved performance, increased memory capacity, and the ability to handle more complex calculations.

"Passing of Peregrinus" refers to a work attributed to the ancient Greek philosopher and satirist Lucian of Samosata, who lived in the 2nd century AD. The text is a satirical account that describes the life and death of Peregrinus Proteus, a Cynic philosopher who became notorious for his self-promoting antics and eventual dramatic suicide by immolation during the Olympic Games.

"Phantasiai" can refer to various concepts depending on context, but it is primarily known in the realm of philosophy and psychology. The term is derived from the Greek word "phantasia," which translates to "imagination" or "appearance."

OGAS, which stands for "Oganization for General Automatic Systems," was a proposed Soviet project in the 1970s aimed at creating a nationwide computer network for managing the economy and various aspects of society. The project was envisioned to integrate computer technology to support real-time data processing, central planning, and information exchange across various sectors.

VAX, short for "Virtual Address eXtension," refers to a family of computers that were designed and produced by Digital Equipment Corporation (DEC) in the late 1970s and 1980s. VAX computers were known for their complex instruction set computer (CISC) architecture and were widely used in various applications, including business, scientific, and academic environments.

The Atlantis Expedition typically refers to an exploration effort aimed at locating the legendary lost city of Atlantis, which has been a subject of myth and speculation for centuries. The concept of Atlantis originates from the writings of the ancient Greek philosopher Plato, who described it as a powerful and advanced civilization that eventually sank into the ocean. Various expeditions have attempted to find evidence of Atlantis, exploring different locations around the world, including the Mediterranean, the Caribbean, and Antarctica.

A diaphone is a type of musical instrument, specifically a kind of brass instrument that employs a double reed to produce sound. Traditionally, the term "diaphone" is more commonly associated with a type of mechanical device known as a diaphone foghorn, which is used in maritime settings to signal ships in foggy conditions. The diaphone foghorn generates sound by forcing air through a pair of reeds that vibrate to produce a distinctive, low-frequency tone.

Electronic navigation refers to the use of electronic devices and systems to assist with the navigation of vehicles, including ships, aircraft, and land vehicles. This method replaces or complements traditional navigation techniques, such as using maps, compasses, and celestial navigation. Key components of electronic navigation include: 1. **Global Navigation Satellite Systems (GNSS)**: Systems like the Global Positioning System (GPS) provide precise location information anywhere on Earth, allowing users to determine their position in real time.

La Cartografía Mallorquina, or the Mallorcan Cartography, refers to the historical maps and cartographic works produced in Mallorca, one of the Balearic Islands in Spain. Historically, Mallorca has a rich tradition of cartography, especially during the medieval period and the Renaissance, when it became a hub for navigation and maritime trade in the Mediterranean.

A "lee shore" is a nautical term referring to a shore that is situated downwind from a vessel. This means that the wind is blowing towards the shore, which can create hazardous conditions for boats and ships, especially during storms. When a vessel is approaching a lee shore, it risks being driven onto the land, which can lead to grounding or shipwreck.

Q-guidance refers to a method of providing guidance or support in a process, often leveraging qualitative data and analysis. While the term itself can be context-dependent, it typically involves the integration of qualitative insights to assist with decision-making, planning, or problem-solving.

Radar navigation is a technique used to determine the position and movement of objects, typically in aviation, maritime, and terrestrial applications, by using radar technology. The term "radar" stands for "Radio Detection and Ranging," which involves the transmission of radio waves and the analysis of their reflections off objects. Here's how radar navigation works: 1. **Transmission**: A radar system emits a pulse of radio waves into the atmosphere or over the surface of the earth.

Navigable servitude is a legal concept primarily in the context of property law in the United States that refers to the right of the public to navigate certain bodies of water, which may include rivers or lakes, despite the property rights of adjacent landowners.
