HOW RADIO WAS INVENTED

The invention of radio communication, although generally attributed to Guglielmo Marconi in the 1890s, spanned many decades, from theoretical underpinnings, through proof of the phenomenon's existence, development of technical means, to its final use in signalling.
The idea that the wires needed for electrical telegraphy could be eliminated, creating a wireless telegraph, had been around for a while before radio based communication. Inventors attempted to build systems based on electric conduction, electromagnetic induction, or on their own theoretical ideas. Several inventors/experimenters came across radio waves before they were proven to exist but it was written off as electromagnetic induction at the time.
The discovery of electromagnetic waves, including radio waves, by Heinrich Rudolf Hertz in the 1880s came about after over half a century of theoretical development on the connection between electricity and magnetism that started in the early 1800s and culminated in a theory of electromagnetism developed by James Clerk Maxwell by 1873, which Hertz finally proved.
The development of radio waves into a communication medium did not follow immediately afterwards. After their discovery Hertz considered them of little practical value and other experimenters who explored the physical properties of the new phenomenon, such as Oliver Lodge and Jagadish Chandra Bose, while transmitting radio waves some distance, did not seem to see any value in developing a communication system based on them. In their experiments they did develop electronic components and methods to improve the transmission and detection of electromagnetic waves.
In the mid 1890s, building on techniques physicists were using to study electromagnetic waves, Guglielmo Marconi developed the first apparatus for long distance radio communica

 
tion. On 23 December 1900, the Canadian inventor Reginald A. Fessenden became the first person to send audio (wireless telephony) by means of electromagnetic waves, successfully transmitting over a distance of about 1.6 kilometers, and six years later on Christmas Eve 1906 he became the first person to make a public radio broadcast and by 1910 various wireless system came to be referred
 by the common name" radio"

TRADITIONAL INSTRUMENT AMONG THE KAMBA

Image
The Kamba  mbeve  is a good example of the gourd-resonated fiddle. The gourd is ‘inverted and then pierced on both sides by a small bow. A string (formerly a tendon from a cow) is stretched across the membrane at the top and affixed on either side to the bow. The bridge, as stated earlier, is optional. The cylindrical wood-resonated fiddle is more common in western Kenya, and was traditionally used with a bridge. The tuning loops and indents found on similar instruments in the south-eastern parts of Africa 1  are not used in Kenya. Instead the tuning peg which holds the string is turned. The bridge may be moved to either end of the membrane to increase or decrease the tension in the string. Bows Kenyan youth have always used their hunting bows as instruments although not much attention is paid to this form of music. Although the hunting bow is used for entertainment, it must be ritually cleaned if it is to be used for therapeutic purposes by traditional doctors. Among the Kamba,

THE CULTURE AND ECONOMIC ACTIVITY OF EARLY MAN . Early human cultural and economic activities can be looked at under various Stone Age periods. The type of tools used at every period describe the various stages of human cultural development. Initially the tools were made of stone hence the term stone age. The early human cultural and economic practices have been divided into three Stone Age periods. These are: The Early Stone Age The Middle Stone Age The Late Stone Age Early Stone Age dates from approximately 2.5 million years ago until about 200,000 years ago. It includes the earliest record of human tool making and documents much of the evolutionary history of the genus Homo. The Early Stone Age has been divided into three main technological phases. These are the Pre-Oldowan, the Oldowan and the Acheulean. Eerly stone age period. Early Stone Age existed 2.5 million years ago. It was the longest of the stone ages. Some of the earliest archaeological finds of early st

TRADITIONAL WAY OF LIGHTING FIRE AMONG MASAI

Image
As they say culture difference should not separate  us from each other but rather cultural diversity brings strength that can benefit all humanity and that is why  the Masai  have never abandoned their culture  and they put it in practice  day after  the other. They put into practice  the invention of fire by Homo erectus who was  the first creature to invent fire  around 1.7 to 1.2 years ago. masai have copied  this from the homo erectus and they use the same method  to  light fire from generation to generation  so as to Abandon  the new error technology and remain with their culture.
