Each generational comes in contributed to the advancement of technology.

The discovery of photographic plates by Henri Becquerel, shown that photographic plates were being fogged by unknown radiation.He later discovered the radioactivity but he could not account for disintegration of the elements and radioactive substances..

Ernest   Rutherford extended the phenomenon,it was established that ,there are three distinct types of radioactive involved.. He discovered  the disintegration of the elements & radioactive substances.

Most of the complex electronic devices and system developed today,were the outgrowths of early development in technology...

In the early days,many scientists were reluctantly to accept the existence of atoms because its could be not seen in a conventional sense.The atom was viewed as indivisible elementary particles...

There are natural phenomenons that are still remain unexplained by the scientists..The ancient Greeks observed that several celestial bodies(moon,sun,star) were moving backward direction and forth against the fixed background called the planet..

The method of trigonometry was developed by Hipparchus this enable the determination of astronomer distances by observation of the angular position of the celestial bodies.

Aristarchus of Samos determined the sizes and distance of the sun and moon relative...
