The first application of electricity that was put to practical use was electromagnetism. [18]
There’s something almost magical about the way boomerangs arc through the air and return to the hand of the thrower. Watching them cut through the sky on their wide trajectories can provide ...

[31] Quartzite is one of the main materials Aboriginal people used to create flakes but slate and other hard stone materials were also used. [29] [32] [33] Flakes can be used to create spear points and blades or ...
