The Age of Industrialisation

Do you not see rapid industrialization  as a time of progress and modernity ? D you think that the spread of railways and factories, and construction of high-rise building and bridges is a sign of society's development ? Is industrialization always based on rapid technological development ? Can we today continue to glorify continuous mechanization of all work ? What has industrialization meant to people's lives ? To answer such questions we need to tun to the history of Industrialization. In this chapter we will look at this history by focusing first on Britain, the first industrial nation, and then India, where the pattern of industrial change was conditioned by colonial rule.

Meteoroid impact triggers bright flash on the moon


A NASA satellite orbiting the moon is now on a hunt for the newly formed crater, which scientists estimate could be as wide as 66 feet (20 meters).
The flash was so bright that anyone looking at the moon at the moment of impact could have seen it without a telescope, NASA said.

North Pole shifts due to global warming


The North Pole has shifted east because of ice sheet loss caused by rising temperatures, a new study published in Geophysical Research Letters has found, according to the scientific journal Nature.
The pole drifted southeast toward northern Labrador, Canada, at a rate of about 6 centimeters per year between 1982 and 2005. But since 2005, the direction and speed of the pole's journey changed. It started moving rapidly east towards Greenland at a rate of more than 21 centimeters per year.
