They were probably invented sometime during the Iron Age. I.e. at a time when there were tools available to cut them etc.\nConstruction materials vary according to availability of materials. So, in London for example, clay was abundant so most houses are made of bricks. New Zealand houses are generally made of timber etc.\nSo cinder blocks would be probably something you would have found in volcanic areas.\nThe modern cinder blocks would have to be invented after the development of coal fired power stations.

Actually, it is documented.  The pulley was discovered by Archimedes.  He is known for his extensive work in geometry; and the invention of the lever and pulley. He also created a range of mechanical devices for the defense of his homeland - the catapult and a mirror system (for focusing the sun's rays on an enemy's boat causing it to catch fire). \n\n\nBorn: ca. 287 B.C. \nBirthplace: Syracuse, Sicily \nDied: ca. 212 B.C. \nBest Known As: Ancient Greek mathematician who said "Eureka!"

Almost certainly copper, which can be found as the native metal, and in ores which are so easily smelted that they could have been discovered accidentally.  Wikipedia suggests 7500 BC, compared to 4000 BC for silver and gold, and noticeably later for iron.\n\nYou could get an argument from somebody about carbon, because charcoal was being used for painting and decorating caves at least 30,000 years ago, and it's not got a lot of impurities compared with pure carbon.

It was the iron age.. we had iron tools.. They used sandstone.. soft and easy to cut.\nThey had slaves.. lots and lots of slaves and plenty of time.\nRamps. they built ramps to get the stones into place rather like they built cathedrals in europe by filing the insides with dirt until the roof could support itself.\nWasn't it good they inveted pulleys and scaffolding...

During the period of the 18th and 19th century many technical developments were made in the locking mechanisms that added to the security of common locking devices.  It was during this period that America changed form importing door hardware to manufacturing it and even exporting some.  New applications for cast iron, brass and clay completely changed the appearance of the locks that could be bought.  The development through the years of locking devices was carried out by hundreds of individuals all over the world.  To put America's locks at a reasonable price you must only realize that the Chinese had, in common use before the year 1000, a strong, small lock, operated by a relatively easy to carry key. In the years before dynamite was discovered in 1867, the key was everything. Without the key a thief had little hope of opening a locked strongbox or door.  For this reason the shape of a key as well as number of wards cut into it were varied to meet the needs of the material being protected.  Blacksmiths in the Colonies made many locks, as well as their other products. They could not keep up with the demand for locks as the country expanded even though some specialized in just lockmaking.  These men were known as Whitesmiths as they filed and polished their products, unlike the blacksmith who left the surface much as it came from forge.  Lockmaking required the skills common to the Blacksmith plus lathe turning, spring tempering, rivet and screw making, precise fitting and hole punching.  Sometimes in the same shop, brass casting was done for the knobs and escutcheons that were used.  The First American iron works was erected at Sagus, Mass in 1646.  Brass Foundries and Iron furnaces, as they were called, such as Hopewell, Isabella and Warwick Furnace all near our business in Chester County Pennsylvania produced a multitude of common and specialized products.  But like the Whitesmith, the demand was greater that they could meet.  It is for these reasons that is safe to assume that over 80% of the Iron locks and more that 90% of the Brass Locks used in this country before 1800 were imported. \n\nMolded Edge locks produced in England were popular with people of means for their main doors through the late 1700's both here in America and in England.  Just as the Dutch, German, Swedish, English and French carpenters built houses of a type that they knew in their homeland, so did the locksmith create locks that were familiar to him. \n\nThe plate latch is based on an English pattern. There are many different latches designed by different countries, each one unusual in it's own right.  The Dutch elbow latch, the Moravian latch, the French mortised locks with lever handles of brass and many more.  Iron locks, thumb latches, bar latches, key locks, stock locks, Carpenter patent locks and other devices were used in great quantity. \n\nOn Carpenter locks, they were widely used in the East and South and they were all made in England.  The latching bar that lifted through a brass rimmed keeper is the patented design and the patent was issued in 1820. \n\nIn all there were about 20 companies producing these locks, under license, from Carpenter.  To confuse the historians that like to have clear cut dates on everything, according to the noted Pa. restoration architect, G. Edwim Brumbaugh, the house at Pottstown, PA known as Pottsgrove Mansion was fitted with Carpenter Locks when it was built in the 1750's.  It is strange to note that this lock as common as it is in this country, is, as far as we know, completely absent in England.  Could it be that they were all made for export? \n\nIf a date were required to be set for the ending of handcraftsmanship in locks, I would use 1840. This corresponds to the beginning of the Industrial Revolution in this country, and is followed closely by mass production.  In 1831, Frederick T. Stanley established the first factory for the manufacture of, not the making of, locks in New Britain Co

Johannes Gensfleisch zur Laden zum Gutenberg (c. 1398 – c. February 3, 1468) was a German metal-worker and inventor who achieved fame for his contributions to the technology of printing during 1447, including a type metal alloy and oil-based inks, a mould for casting type accurately, and a new kind of printing press based on presses used in wine-making. The exact origin of Gutenberg’s first presses is apparently unknown, and several authors cite his earliest presses as adaptations of heavier binding presses which were already in use. Tradition credits him with inventing movable type in Europe — an improvement on the block printing already in use there. By combining these elements into a production system, he allowed for the rapid printing of written materials, and an information explosion in Renaissance Europe. Yet, it must be noted that an iron printing press was first invented by Korea's Goryeo dynasty in 1234, 216 years ahead of Gutenberg's feat in 1450.

The first Argonauts of 1848 used quite primitive mining tools: knives, spoons, a shovel, and a pan for washing the gold. Since these miners could only dig out bigger nuggets with such primitive equipment, they had to work on rich gold deposits. In the same year, technical improvements such as the cradle, the rocker, the long tom, and river damming, basically all known since the Middle Ages, were introduced by the more experienced Mexicans. The cradle and the rocker both worked on the same principle: wooden boxes with the top and front piece missing and a sieve on the bottom side through which the dirt containing gold was washed. On the bottom horizontal wooden bars slowed the incoming water down and helped to separate dirt from gold. With a handle on the side of the box, the whole mechanism could be rocked. The rocker required 3 or 4 people to work, one to shovel the dirt into the machine, one responsible for the water supply, and a third one to move the handle. Contrary to the individual washing with the pan, this more efficient technique required miners to find partners, thus establishing small mining groups of 3 to 9 people.\n\nThe long tom functioned similarly to the rocker but increased its efficiency. It also had the shape of a trough, but it was much larger, 12 to 15 feet long and about 2 feet wide. Mainly made out of wood, it had a metal bottom with a sieve and a ripple box at its end. This machine was put up with a slight slope, thus facilitating the water flow. While one man shoveled dirt into the long tom, making sure that the water was running, another mixed water and dirt while taking out big stones that could damage the sieve. At the end of the day, the dirt was taken out of the box and washed in a pan. Six to eight men had to work a long tom to fully exploit its capacities. A few miners started to employ the long tom at the end of 1848, and by 1850 it became a common machine.

Weapons were invented before we have records. Simple weapons such as spears, rock axes and bows and arrows were used in hunting from the Stone Age. Stone tools were made from a variety of different kinds of stone. For example, flint and chert were shaped for use as cutting tools and weapons, while basalt and sandstone were used for ground stone tools, such as quern-stones. Wood, bone, shell, antler and other materials were widely used, too. During the most recent part of the period, sediments like clay were used to make pottery. A series of metal technology innovations characterize the later Copper Age, Bronze Age and Iron Age. Homo Erectus is known to have developed hand axes a million years ago. Arrows date back to 20,000 BC.\n\nThe first firearm was the arquebus which was introduced in the 15th century. The arquebus came into greater prominence during the Battle of Pavia in 1525. The defeat of French knights by the heavy fire of Spanish arquebusiers inspired other people to adopt the weapon. Arquebusiers also played an important role in Cristóvão da Gama's battles against the superior numbers of his Muslim opponents in Ethiopia during the 1540s, and later in the Moroccan victory over the Songhai Empire at the Battle of Tondibi in 1590.\n\nBy the later 16th century, muskets began to slowly replace the arquebus across Europe. Firearms have steadily been improving since.
