How did technological developments take place in the song dynasty?

Technological developments that took place in the Song Dynasty were the magnetic compass, the printing press, and the gunpowder.

They developed the magnetic compass for navigation. It helped ships travel great distances with no land in sight.

The printing press began in Tang China and improved on Song Dynasty. Printing later spread around the world, revolutionizing learning, communications, and connections.

Gunpowder was a Chinese innovation.  Firstly, it was used in Tang Dynasty for fireworks, and then by Song armies in rockets, grenades, etc. This development transformed the way of wars.

These technological inventions influenced the course of world history.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
