Universe has always baffled us and we loved to explore its 'limitless' limits. With the advent of the 20th century, we devised a method to send messengers (satellites) up there to carry out experimental observations on various aspects that needed clarification. However, there was a time before the birth of satellites when human beings relied on their intuition to develop theories, which they more or less proved using early inventions like telescopes. Here, we are going to discuss about 'cosmic rays', something which has caught the limelight in recent years due to its ever fascinating principles and behavior. THE START : Let's go back to the year 1912. This year is particularly important for two reasons, the tragedy of RMS Titanic and Hess's Balloon Experiment. Portrait 1: Victor Hess The experiment conducted by Victor Hess opened a new era of cosmic ray exploration. Back then scientists believed that radiations came from three sources: 1) Earth's atmosphere ...
A humble attempt to make science easy, interesting and exciting...
