The controlled use of fire, was one of mankind's first great innovations. Fire allows us to produce light and heat, to cook plants and animals, to clear forests for planting, to heat-treat stone for making stone tools, to keep predator animals away, and to burn clay for ceramic objects.

As a way to efficiently carry goods for long distances, wheeled vehicles allowed for the broadening of trade networks.

Indians, as early as 500 BCE, had devised a system of different symbols for every number from one to nine. This notation system was adopted by the Arabs who called it the hind numerals. Centuries later, this notation system was adopted by the western world who called them the Arabic numerals as it reached them through the Arab traders.

Marked out in minute subdivisions with amazing accuracy, the calibrations correspond closely with the hasta increments of 1 3/8 inches, traditionally used in the ancient architecture of South India.

The binary number system was first described by the Vedic scholar Pingala, in his book Chandahśāstra, which is the earliest known Sanskrit treatise on prosody (the study of poetic meters and verse).

It is low-cost and eco-friendly because the stove is supplied or powered by water. It does not require gas or even electricity. This invention also can work with any water as long as it will not discharge C02.

Ruperta David (aka Aling Tentay) was responsible for its accidental discovery in 1949.

This ink was very innovative in the past and was further developed to work with Parker Pens. This ink isn’t just quick drying, it was also water resistant, doesn’t clog the pen opening, doesn’t blot and won’t fade. This ink is considered one of the best-selling inks for fountain pens.

At first they tried to keep the discovery secret. But before 1300 a friar from Pisa, Alessandro della Spina, was making spectacles for everyone who wanted them and his business boomed. The ground quarts magnifying lenses of this incredible innovation could help people with long as well as short sight.

The arrival of Norman knights in 1066 signalled the start of the medieval period, and over the next 450 years their armour and weapons were ingeniously updated to make them more powerful and less vulnerable fighting machines.

This was a tiny room with a seat pierced by a hole through which the waste dropped into a moast or straight onto the ground. Many monasteries, however, developed a more efficient means of sewage disposal, building their communal toilets above streams or specially created watercourses which carried away the “product”.
