Rolling ball clock by William Congreve, British Museum.

In a dystopian parallel universe, thousands of scientists and supporters took to the streets in the name of science. In this world, the prerequisite of verifiable fact seems to be declining in importance. It’s so bad, even introverts showed up. And just because we can, the march was partly attributed to Trump.

Humans are inherently inquisitive. Take the children above deciphering Congreve’s rolling ball clock. Not the most accurate measure of time, but a physical manifestation that’s food for thought for a young, hungry mind. There will always be need to explore and discover; best to do this with the evidence-based knowledge, not alternative facts.

The shell roof of the Sydney Opera House.

Sydney is large and sprawling, but compared to other major cities around the world, there isn’t much that’s distinctive in it, especially when it comes to landmarks.

All the eggs are in one basket with the Opera House. If you’re into beaches then Bondi and Manly might be on your todo list, otherwise, you’ll likely be spending your time at Circular Quay around the Opera House, the Harbour Bridge, and The Rocks, along with every other visitor.
