Why can sand think?
Semiconductors
Start with the material at the heart of a microchip. What makes silicon so useful?
SMALL CHANNEL. BIG QUESTIONS.
The world is
pretty wild.
Let’s explain it.
Things I didn’t understand, explained simply.
From the stuff under our feet to the chips changing everything. One good question at a time.

Silicon.
Supercomputers.
How do we get from a crystal to a computer? Silicon follows the ideas, inventions and people that made it possible.
Start with the basics. Build up the picture. See everyday technology a little differently.

THE CURIOSITY BEHIND THE CLIPS
You don’t need to
be an expert.
Just interested.
Aussie Science Clips starts with the questions a curious non-expert actually asks. Why can sand think? What’s inside a chip? How did we get from a single transistor to data centres full of GPUs?
Made in South Australia, the channel works through the answers from first principles, with animated diagrams and the stories of the people who figured them out.
