Animal breeding
Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, or other products. It includes day-to-day care, management, production, nutrition, selective breeding, and the raising of livestock. -

Minning
Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times -

Forge
While the use of iron has been dated back to 4000 BC, the Hittites were the first to extract the ore, smelt it and fashion weapons – thus setting off the Iron Age around 1200 BC. In Asia, iron working developed at about the same time; iron Chinese artifacts have been unearthed dating back to around 600 BC. From those two places, using iron for weapons and tools spread quickly across the globe, except in the Americas where the natives continued to hit each other with rocks. -

Sword making
The primary techniques are forging and stock removal. Forging uses heat to bring the material to a malleable state. The material is then hammered to shape, typically using hammer and anvil together with specialized set and fuller tools depending on the particular technique. -

Construction
When the architects and engineers get done mucking about, the contractors take over. Once there was agriculture and a reason to stay in one place, the first huts were constructed by the people who would live in them. As cities grew during the Bronze Age, professional construction workers – just bricklayers and carpenters at first – arose. This new class of skilled workers, including lots of slaves, literally laid the foundations for civilization. -

Armor Making
armor, protective clothing with the ability to deflect or absorb the impact of projectiles or other weapons that may be used against its wearer. -

Banking
The smallest Renaissance banks were pawn banks, which lent money to individuals who pledged some form of personal property as security for the loan. Pawnbrokers charged interest on these loans, even though doing so violated the church ban on usury—the practice of charging interest for the use of loaned money. -

Rifling
Rifling is merely the cutting of helical grooves into the inner part of a gun barrel so as to induce spin in a ball or bullet which serves to gyroscopically stabilized the projectile, giving it greater accuracy and range. In short, all this means is that it took a skilled marksman to hit anything specific with a smoothbore musket, but any fool with a steady hand has a fair chance of success firing a rifle at a target. -

Chemistry
As astronomy evolved from astrology, chemistry evolved from another pseudoscience: alchemy. Alchemy spans four millennia and three continents; never underestimate mankind's ability to believe in the irrational. The roots of Western alchemy can be traced to Hellenic Egypt, where Zosimus of Panoplies claimed that the ancient priests had discovered a way to transmute metals from one to another (such as lead to gold, the “Holy Grail” for alchemists). -

plastic
Synthetic or semi-synthetic organic polymers derived (generally) from petrochemicals of high molecular mass that are incredibly durable, malleable, lightweight and now pervasive in modern civilization. Plastic. It comes in many forms, some tougher, some more flexible, some with a greater or lesser tolerance to heat. Plastic can be molded, pressed, or extruded into virtually any shape desired. -

robtics
In 1942 AD, the science fiction author Isaac Asimov proposed three “laws of robotics.” In 1948 the American mathematician Norbert Wiener formulated the “principles of cybernetics” as the basis for practical robotics. And in 1961 the first programmable robot – “Unimate” – was constructed to lift and stack hot pieces of metal from a die casting machine. -

Advanced AI
In the ensuing decades since the Turing Test was proposed, artificial intelligence has become more widespread and more robust in terms of its capabilities, particularly in the analysis of large data sets. An AI in these cases often “studies” a problem through developing and testing hypotheses about underlying patterns in the data, matching them against the data, and creating iteratively refined models with considerable explanatory power.
