The very first knife was likely a sharp bit of rock. Since then we added handles, changed blades to metal, changed metals several times, made folding knives, knives with more than one blade, combined knives with tools (Swiss Army Knives. Leatherman), made knives to go on guns (bayonets) made REALLY big knives (swords) and made electric knives (electric carving knives) Some knives are now made with blades that are ceramic- a form of stone. Hey- this is where we started!
Life is different now because we have developed and invented more and more since then. We created factories, which were developed, improved, and are what we have today.
The KA-BAR knife was first developed and manufactured by the Tidioute Cutlery Company. KA-BAR knives were used throughout World War 2, and see heavy use today from both civilians and soldiers.
The Pocket Knife comes from the early Iron Age but they were not the same pocket knives you see today. The 15th century is when Locking Knives were first known to exist.
It was developed by Dr. Sam Hurst. He invented the first touch sensor which was not transparent and hence not like the touchscreens like today in 1971 at Kentucky University. In 1974, he developed transparent touchscreens we use these days and in 1977 the whole technology used today was developed and patented it.
Sputnik was developed by the USSRSputnik 1 was launched from kasakhstan where the baikonor cosmodrome is today
They invented an alphabet from which developed the Greek and Roman alphabets, and hence today's alphabets.
Actually,the beginning was from Abacus, developed by the Egyptians.Slowly and gradually it came upto the analytical machine developed by Charles Babbage.This machine was capable of storing data as well as calculations.As,it was basic ,people only developed it .And the result is today's modern computer.So,as computer's base is mathematics therefore from the time it has been invented it is related to mathematics.
The barber chair as known today was invented around 1895. The first hydraulic chair was developed by the Koken company.
The first computer was invented by Charles Babbage in 1822. The computer he invented was not the type that is used today but a machine that can compute math problems. On the other hand, the invention of the Internet cannot be credited to one person since it was the work of pioneering programmers which have been developed through the years until it became today's version of the Internet.
The violin as it is today was probably invented in northern Italy.
the stone age people invented wheels which later on turn'd into tires. they also made sharp tools which we use today as knives.
