A telescope is an optical instrument used to observe distant objects, such as stars, planets, and galaxies. It uses lenses or mirrors to gather and focus light, allowing the viewer to see objects far away in greater detail. Telescopes are commonly used in astronomy to study celestial bodies and in science to explore the universe. There are different types of telescopes, such as refracting telescopes, which use lenses, and reflecting telescopes, which use mirrors. Telescopes can be found in observatories or used for personal stargazing.

A switch is a device used to open or close an electrical circuit, allowing the flow of electricity to be turned on or off. It is commonly used to control various electrical appliances, such as lights, fans, and other devices. Switches come in different types, including toggle, rocker, and push-button, and can be installed in walls, outlets, or directly on appliances. They are an essential part of any electrical system, providing an easy way to control power and ensure safety. Switches are usually simple to operate and can be found in nearly every room of a building.

A crane is a large machine used for lifting and moving heavy loads, typically in construction, shipping, or industrial settings. It consists of a tall, movable arm or boom with a hook or other lifting device at the end, which can be raised, lowered, or extended to pick up and transport materials. Cranes are powered by electricity, diesel, or pressurized fluid and can be stationary or mobile, mounted on trucks, or positioned on construction sites. They are essential for handling heavy equipment, large building materials, or shipping containers, making tasks that would be difficult or impossible by hand much easier and safer.

A laboratory is a controlled environment where scientific experiments, research, and practical learning activities are conducted. It is equipped with tools, instruments, and materials needed for conducting tests, measurements, or experiments. Laboratories are commonly found in schools, colleges, and universities, especially in subjects such as science, chemistry, biology, and physics. They allow students and researchers to apply theoretical knowledge in hands-on experiments, fostering a deeper understanding of scientific principles and processes.

The idiom "guinea pig" has its origins in the early 17th century when guinea pigs were first introduced to Europe. These small rodents are not native to Guinea but were imported to Europe via Guinea, a region in West Africa. The exact reason for the association with Guinea remains unclear, but it is believed that European traders may have used the term "Guinea" to refer to any distant or exotic place. Guinea pigs were considered exotic animals when they were first brought to Europe, and the name likely reflects their foreign origin. In modern English, "guinea pig" is used metaphorically to refer to a person or creature used in experiments, tests, or trials to gather information or conduct research, often at some risk to their well-being.
