So why was it introduced? RoHS was introduced to improve the welfare of consumers, distributors, manufacturers, and the environment. Since the early 20th century, chemicals have been introduced into manufacturing for their useful properties such as the luminescence of radium or the low melting point...
a school of geneticists whose star exponent, Thomas Hunt Morgan, showed that by breeding millions of fruit flies – and sometimes spiking their food with the radioactive element radium – he could produce mutated traits, such as new eye colours or additional limbs. These were not the tiny...
from. In fact, to this day, it is still quite unexplained where this energy comes from.” Another scientist, a chemist living in France, Marie Curie, won two Nobel medals for her work with radioactivity; she discovered the elements ʻradiumʼ and ʻpoloniumʼ [contained ...
