"We have won so far because geographical isolation gave us about a week of decision-making space to lock down hard." The extra week was helpful – but much more important was being prepared to make that decision to lock-down hard. The Tory party would have been incapable of such a decision no matter how many extra weeks they were handed – and that was Ed's point. A National government here would have (most likely) been unable to make that decision. Scomo looked like he wasn't capable of that decision – but fortunately state premiers took it out of his hands. It took some guts to defy th...

Population has always been a critical driver of events and prior to the Industrial Revolution we lived in a zero sum world, with energy and resources effectively limited to that which could be harvested from photosynthesis, one person’s gain was at the limit, always someone else’s loss. Very low density hunter gather populations could thrive (often quite nicely) because they rarely approached their local resource limits, but the invention of agriculture changed this dramatically. The next 10,000 odd years of recorded history is a long story of local competition for fundamentally constrai...

A great read Robert, thanks. This idea of the gift economy is deeply culturally bound in Asia, where at least twice a year families gather, and gifts, usually of money are exchanged. The head of the family (usually a grandmother) gets the bulk of the serious giving, and status is attached to generosity to her. Children also receive gifts, for which they bow to the responsible relative. One need not give gifts, but if not you lose the opportunity to gain status, and the children will not bow to you. Grandmothers often recycle some of their gifts to the grandchildren or single adolescents. Gove...

By Ray Norris, Professor, School of Science, Western Sydney University Ray Norris, Author provided At the very largest scale, the Universe consists of a “cosmic web” made of enormous, tenuous filaments of gas stretching between gigantic clumps of matter. Or that’s what our best models suggest. All we have seen so far with our telescopes are the stars and galaxies in the clumps of matter. So is the cosmic web real, or a figment of our models? Can we confirm our models by detecting these faint gaseous filaments directly? Until recently, these filaments have been elusive. Bu...

Using the eROSITA X-ray telescope onboard the Spectrum-Roentgen-Gamma (SRG) space observatory and CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP), astronomers have spotted a 49-million-light-year-long intercluster filament in the merging galaxy cluster system Abell 3391-Abell 3395, confirming current ‘Big Bang’ ideas about the origin and evolution of the Universe. Simulation showing the distribution of hot gas (left), compared with the eROSITA X-ray image (right) of the Abell 3391-Abell 3395 system.
