Metamaterials scientists specialize in the study and development of metamaterials—engineered materials with properties not typically found in natural substances. These materials derive their unique characteristics not from their composition but from their carefully designed structures. Metamaterials can manipulate electromagnetic waves in innovative ways, leading to applications in areas such as optics, telecommunications, and cloaking technology.

Superconductivity is a phenomenon observed in certain materials where they can conduct electric current without resistance when cooled below a certain critical temperature. This state allows electric current to flow indefinitely without energy loss, making superconductors highly valuable for a variety of applications. ### Key Aspects of Superconductivity: 1. **Zero Electrical Resistance**: In the superconducting state, cooper pairs (pairs of electrons that move together at low temperatures) allow for the flow of electricity without energy dissipation.

As of my last update, there is no widely recognized figure named Katherine Crothall. It's possible that she may be a private individual, a lesser-known public figure, or a character from a work of fiction.

Hans Lipperhey was a Dutch eyeglass maker and is often credited as the inventor of the compound telescope. He lived during the early 17th century, and in 1608, he applied for a patent for his invention in the Netherlands. His telescope design allowed for the magnification of distant objects, which ultimately contributed significantly to advancements in astronomy.

Atira asteroids, also known as Apohele asteroids, are a group of asteroids that have orbits entirely within the orbit of Earth. This means that their maximum distance from the Sun is less than that of the Earth's average distance from the Sun, which is about 1 astronomical unit (AU). Atira asteroids are named after the first discovered member of this group, 163693 Atira, which was identified in 2003.

Callisto is one of the largest moons of Jupiter and the outermost of the four Galilean moons, which also include Io, Europa, and Ganymede. Discovered by Galileo Galilei in 1610, Callisto has a diameter of about 4,820 kilometers (about 2,995 miles), making it the third largest moon in the solar system.

In 2019, several asteroids made close approaches to Earth. Here are some notable encounters: 1. **2019 EA2** - Approached on January 5, 2019, at a distance of about 0.0051 AU (astronomical units), which is approximately 2 million kilometers (1.2 million miles).

A list of minor planets named after places includes celestial bodies (typically asteroids) that are named in honor of geographical locations, regions, cities, and other significant landmarks. These names often reflect cultural, historical, or personal significance associated with the area being honored. While I can't provide an exhaustive list, here are some notable examples: 1. **243 Ida** - Named after the mountain Ida on the Greek island of Crete.

The list of named minor planets from 250,000 to 299,999 is quite extensive, and it's continuously updated as new minor planets are discovered and named. For detailed information about each minor planet's name, designation, and other relevant data, it is best to refer to resources like the International Astronomical Union (IAU) or specific databases such as the JPL Small-Body Database.

The list of named minor planets ranging from 30,000 to 39,999 includes astronomical objects that have been given specific names. These names can be based on a variety of themes, including mythology, notable individuals, or other culturally significant concepts. The minor planets in this range are typically numbered and named by the International Astronomical Union (IAU) after their discovery.

The list of named minor planets numbered from 60000 to 69999 includes various small celestial bodies that have been discovered and officially named. Each name is typically chosen to honor notable individuals, places, myths, or other entities. Here’s a brief overview of some named minor planets in that range: - **60000**: 60000 Ptolemaios - Named after the ancient Greek astronomer Claudius Ptolemy.

The "List of named minor planets: A" is a compilation of minor planets (also known as asteroids) that have been given designated names. This list is part of a larger catalog maintained by the International Astronomical Union (IAU), which officially assigns names to celestial bodies. Minor planets are typically given names that are significant to the discoverer, mythology, geography, or science.

The "List of named minor planets" for those starting with the letter "H" includes minor planets (or asteroids) that have been formally named. These named minor planets can include a variety of interesting objects from the asteroid belt, Kuiper belt, and other regions of the solar system.

The "List of named minor planets: X" refers to a compilation of minor planets (or asteroids) that have been designated with names that start with the letter "X." Minor planets are small celestial bodies that orbit the Sun, and many of them are named after various figures from mythology, history, literature, and other cultural references.

The list of minor planets from 103001 to 104000 refers to a collection of small celestial bodies that orbit the Sun, primarily in the asteroid belt. These minor planets, also known as asteroids, are numbered sequentially starting from 1. Each minor planet is assigned a unique number upon discovery, and many also have specific names given by the discoverers.

The list of minor planets from 116001 to 117000 includes a range of asteroids that have been discovered and cataloged. Each entry typically includes information such as the minor planet's provisional designation, its number, and sometimes its name if it has been officially assigned one.

The List of minor planets from 125001 to 126000 is a compilation of numbered asteroids and minor planets that have been cataloged by the International Astronomical Union (IAU). Each minor planet is assigned a unique number and often has a name that is either descriptive or honors a person, place, or cultural theme.

The "List of minor planets: 130001–131000" refers to the catalog of minor planets (also known as asteroids) that have been numbered in the range from 130001 to 131000. Minor planets are celestial bodies in orbit around the Sun that are not classified as traditional planets or comets. This list includes their respective names, discovery dates, and sometimes additional information regarding their physical characteristics or orbits.

The "List of minor planets: 136001–137000" refers to a catalog of minor planets (also known as asteroids) that have been designated with numbers between 136001 and 137000. Minor planets are small celestial bodies that orbit the Sun, and they are typically categorized into asteroids and comets.

The list of minor planets numbered between 147001 and 148000 includes various small celestial bodies primarily located in the asteroid belt. Unfortunately, I cannot provide a detailed list of all the minor planets within this specific range, as it would require up-to-date catalog data beyond my last knowledge update.
