Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin. The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming.
Wild grains were collected and eaten from at least 105,000 years ago. However, domestication did not occur until much later. The earliest evidence of small-scale cultivation of edible grasses is from around 21,000 BC with the Ohalo II people on the shores of the Sea of Galilee. By around 9500 BC, the eight Neolithic founder crops - emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chickpeas, and flax - were cultivated in the Levant.
Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung, soy and azuki beans. Pigs were domesticated in Mesopotamia around 11,000 years ago, followed by sheep. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and India around 8500 BC.
In subsaharan Africa, sorghum was domesticated in the Sahel region of Africa by 3000 BC, along with pearl millet by 2000 BC. Yams were domesticated in several distinct locations, including West Africa (unknown date), and cowpeas by 2500 BC. Teff and likely finger millet were domesticated in Ethiopia by 3000 BC, along with noog, ensete, and coffee.
The British agricultural revolution introduced four-field crop rotation. The 20th century saw the construction of the first commercially successful gasoline-powered general-purpose tractor in 1911, and the Green Revolution led by Norman Borlaug.

Fusion Power <<-----CLICK
11. Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors.
1. The materials used in fusion power are typically heavy hydrogen isotopes such as deuterium and tritium. These isotopes react more easily than protium (the most common hydrogen isotope), allowing them to reach the Lawson criterion requirements with less extreme conditions. Most designs aim to heat their fuel to around 100 million degrees, which presents a major challenge in producing a successful design.
2. In a fusion reactor, the concept is that neutrons generated from the D-T fusion reaction will be absorbed in a blanket containing lithium which surrounds the core. The lithium is then transformed into tritium (which is used to fuel the reactor) and helium.
As a source of power, nuclear fusion has a number of potential advantages compared to fission. These include reduced radioactivity in operation, little high-level nuclear waste, ample fuel supplies, and increased safety. However, the necessary combination of temperature, pressure, and duration has proven to be difficult to produce in a practical and economical manner.

Early 20th Century: The history of nuclear fusion began early in the 20th century as an inquiry into how stars powered themselves. In 1920, British physicist Francis William Aston discovered that the mass equivalent of four hydrogen atoms is heavier than the mass of one helium atom, which implied that net energy can be released by combining hydrogen atoms to form helium.
1930s: Quantum tunneling was discovered by Friedrich Hund in 1929, and shortly afterwards Robert Atkinson and Fritz Houtermans used the measured masses of light elements to show that large amounts of energy could be released by fusing small nuclei. In 1932, John Cockcroft and Ernest Walton at Ernest Rutherford's Cavendish Laboratory at the University of Cambridge produced the first man-made fission by using protons from an accelerator to split lithium into alpha particles.
1950s: During the late 1940s and early '50s, research programs in the United States, United Kingdom, and the Soviet Union began to yield a better understanding of nuclear fusion, and investigators embarked on ways of exploiting the process for practical energy production.
1970s: On May 1, 1974, the KMS fusion company achieved the world's first laser-induced fusion in a deuterium-tritium pellet.
Present: As of 2024, no device has reached net power. However, the necessary conditions of plasma temperature and heat insulation have been largely achieved, suggesting that fusion energy for electric-power production is now a serious possibility.

1. Glass Materials & Uses: Glass is a non-crystalline solid that is often transparent, brittle, and chemically inert. It has widespread practical, technological, and decorative uses in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form. The inert and impermeable nature of glass makes it a stable and widely used material for food and drink packaging as glass bottles and jars.
2. Optical Materials & Uses: Optical materials are transparent materials from which optical lenses, prisms, windows, waveguides, and second-surface mirrors can be made. They are required in most optical instruments. Most optical materials are rigid solids, but flexible and elastic materials are used for special functions. Known optical materials include amorphous materials and crystalline materials: Glass, Plastics, Polycarbonate, Poly (methyl methacrylate), Sodium chloride, Strontium fluoride, Synthetic diamond, Zinc sulfide.
3. Laser Materials & Uses: Lasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic, and free-space optical communication, semiconducting chip manufacturing (photolithography), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment. Laser cutting can be used for materials like wood, paper, plastics, glass, leather, foam, fabrics, and metals.
History:
Glass History: The history of glass-making dates back to at least 3,600 years ago in Mesopotamia. Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia, or Egypt. The earliest known glass objects, of the mid 2,000 BCE, were beads.
Optical Materials History: Around 700BC, ancient Egyptians and Mesopotamians started polishing crystals (often quartz) in an attempt to replicate optical abilities that they noticed could be made with water. One of the most famous examples of those original lenses is the Nimrud lens. The term "modern optics" refers to areas of optical research that largely developed in the 20th century, such as wave optics and quantum optics.
Laser History: The principle of the laser dates back to 1917, when Albert Einstein first described the theory of stimulated emission. German physicist Rudolf Walther Ladenburg first observed stimulated emission in 1928. The first working laser was demonstrated by Theodore H. Maiman at Hughes Research Laboratories in Malibu, California.

Solar Power <<-----CLICK
24. Solar power technology primarily uses two types of materials: semiconductor materials for solar photovoltaic cells and materials for concentrated solar power systems. Here's a brief overview:
1. Solar Photovoltaic Cells: Solar photovoltaic cells are made of semiconductor materials that absorb energy from light and transfer it to electrons. The most common semiconductor material used in solar cells is silicon, which represents approximately 95% of the modules sold today. Silicon provides a combination of high efficiency, low cost, and long lifetime.
There are also thin-film solar cells made by depositing one or more thin layers of photovoltaic material on a supporting material such as glass, plastic, or metal. The two main types of thin-film photovoltaic semiconductors on the market today are cadmium telluride (CdTe) and copper indium gallium diselenide (CIGS).
2. Concentrated Solar Power Systems: Concentrated solar power systems use mirrors or lenses to concentrate a large area of sunlight onto a small area. The concentrated light is then used as a heat source for a conventional power plant.
Uses Solar photovoltaic cells convert sunlight into electricity, which can be used to power homes, businesses, and other electrical sources. Concentrated solar power systems, on the other hand, generate thermal energy that can be used to heat homes or produce electricity.
It's important to note that the use of these materials in solar power technologies is heavily regulated to ensure safety and efficacy.
Other Products Include:

Photovoltaic Cells - (Polysilicon, Perovskite, Gallium Arsenide, Germanium, Indium Selenide, Ruthenium, Tellurium, Selenium, Cadmium, Synthetic DNA Photosynthesis, Indium Nitride, Graphene, Zinc, Lead Telluride, Lead Selenide, Lead Antimonide, Cadmium Telluride, Boron Arsenide, Black Silver) - (Fruit, Vegetable Waste) - (Acenes)
History:
The history of solar power is quite fascinating and spans several centuries. Here's a brief overview:
The concept of harnessing solar energy dates back to as early as the 7th century B.C. when humans used sunlight to light fires with magnifying glass materials.
In the 3rd century B.C., the Greeks and Romans harnessed solar power with mirrors to light torches for religious ceremonies.
The photovoltaic effect, or the ability of a solar cell to convert sunlight into electricity, was first proven by French physicist Alexandre Edmond Becquerel in 1839.
The development of solar cell technology, or photovoltaic (PV) technology, began during the Industrial Revolution.
Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system.
Commercial concentrated solar power plants were first developed in the 1980s.
Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems' capacity and production have grown more or less exponentially, doubling about every three years.
In 2022, solar generated 4.5% of the world's electricity4, compared to 1% in 2015, when the Paris Agreement to limit climate change was signed.
The development and understanding of these materials have significantly influenced the evolution of solar power, leading to the wide variety of solar power technologies we have today. It's important to note that the use of these materials in solar power technologies is heavily regulated to ensure safety and efficacy.

Space <<-----CLICK
25. Space technology primarily uses two types of materials: materials for spacecraft and materials for space suits. Here's a brief overview:
Materials for Spacecraft Spacecraft are subjected to extreme conditions such as temperature spikes, gravity shifts, radiation, and pressure. Therefore, the materials used in their construction need to be robust and able to withstand these conditions.
1. Temperature Spikes: Temperatures shift from high to low as an orbiting device moves into the sunlight or behind the Earth's shadow. For example, NASA's Orion spacecraft, designed to travel outside the moon's orbit, will experience temperatures ranging from -101 to 288 degrees Celsius (-150 to 550 degrees Fahrenheit).
2. Gravity: Launching a spacecraft requires overcoming the Earth's gravitational pull, but during the upward momentum of leaving the launching pad, the craft will experience up to three times the force of Earth's gravity.
3. Radiation: Outside the protection of the Earth's atmosphere, radiation levels increase. Materials for Space Suits Space suits are made from multiple layers of material to protect astronauts from the harsh conditions of space. These materials need to be lightweight, durable, and resistant to radiation and temperature changes.
Uses These materials are used in various ways in space technology. The materials used in spacecraft construction are designed to withstand the harsh conditions of space, while the materials used in space suits are designed to protect astronauts from these conditions.
It's important to note that the use of these materials in space technology is heavily regulated to ensure safety and efficacy.
History:
The history of space exploration is quite fascinating and spans several centuries. Here's a brief overview:
The concept of harnessing solar energy dates back to as early as the 7th century B.C. when humans used sunlight to light fires with magnifying glass materials.
The first artificial Earth satellite, Sputnik 1, was launched by the Soviet Union on October 4, 1957.
The first human to go into space, Yuri Gagarin, was launched, again by the Soviet Union, for a one-orbit journey around Earth on April 12, 1961.
Within 10 years of that first human flight, American astronauts walked on the surface of the MoonApollo 11 crew members Neil Armstrong and Edwin ("Buzz") Aldrin made the first lunar landing on July 20, 1969. A total of 12 Americans on six separate Apollo missions set foot on the Moon between July 1969 and December 1972.
Since then, no humans have left Earth orbit, but more than 500 men and women have spent as many as 438 consecutive days in space.
Starting in the early 1970s, a series of Soviet (Russian from December 1991) space stations, the U.S. Skylab station, and numerous space shuttle flights provided Earth-orbiting bases for varying periods of human occupancy and activity.
From November 2, 2000, when its first crew took up residence, to its completion in 2011, the International Space Station (ISS) served as a base for humans living and working in space on a permanent basis.
Since 1957 Earth-orbiting satellites and robotic spacecraft journeying away from Earth have gathered valuable data about the Sun, Earth, other bodies in the solar system, and the universe beyond.
The development and understanding of these materials have significantly influenced the evolution of space exploration, leading to the wide variety of space technologies we have today. It's important to note that the use of these materials in space technologies is heavily regulated to ensure safety and efficacy.

History:
The history of steel and alloy production is quite fascinating:
The production of steel dates back to 2000 BC when people first began making iron and steel tools and weapons.
The process of making steel involves reducing iron ore to iron, purifying the iron, and then adding small amounts of carbon.
The first method of making steel involved heating wrought iron to a high temperature in the presence of powdered charcoal, a process known as cementation.
In the 1850s, Sir Henry Bessemer invented a new steelmaking process, which involved blowing air through molten pig iron to burn off the impurities and thus create steel.
This was later improved upon with the open-hearth furnace and the basic oxygen process, which allowed for the mass production of steel.
Modern steelmaking processes, such as the electric arc furnace process, continue to improve upon these methods.
Alloys, on the other hand, have been used for thousands of years. Bronze, an alloy of copper and tin, was used as far back as 3000 BC. Since then, humans have learned to combine different metals to create alloys with a wide range of properties.
Today, steel and its alloys are used in a wide range of applications, from construction and transportation to appliances and packaging. The development and understanding of these materials have significantly influenced the evolution of our modern industrialized society.
