In numbers: Galactic ambition
Number of would-be space tourists who have paid to take a trip on Richard Branson's Virgin Galactic since the company's inception 14 years ago. Branson now says the company should be in space "in weeks, not months".
Price of a (return) ticket in this still notional universe where Branson can run a commercial space travel business.
Number of years that have passed since Virgin Galactic first predicted it could help people see the orbital sunrise of their dreams, then get them safely back to earth.
Image of the week: Opera backlash
It is one of the 20th century's most famous landmarks, but not even the architectural wonder that is the Sydney Opera House can escape commercialisation. When sporting body Racing NSW said it would be illuminating its famous "sails" with an advertisement for its Everest Cup horse race, protestors were ready for it, shining torches and booing as the lighting display began. With shades of magazine FHM's decision to project an image of model and presenter Gail Porter on the side of London's Houses of Parliament in 1999, Racing NSW wanted to get its event "on the world stage" and said it wasn't expecting such a fierce backlash. Let's just hope Australians are still okay with their architectural jewel being all lit up in green for St Patrick's Day.
The lexicon: Project Sunrise
Project Sunrise is Qantas's name for its challenge to manufacturers Boeing and Airbus to deliver an aircraft capable of flying non-stop from Sydney to the likes of London, New York, Cape Town, Rio de Janeiro and Paris. So far the longest flight Qantas can manage without a need to refuel is from London to Perth in Western Australia, a route it only started doing earlier this year. Now, under Irish chief executive Alan Joyce, Qantas has ambitions to find "the antidote to the tyranny of distance", shrinking the earth and ushering in an era of less painful long-haul travel. Making that jump from 17 hours to 21 hours is, he says, "the last frontier in global aviation". London-Perth is eclipsed in distance only by Qatar Airways' Doha-Auckland route and, from this week, Singapore Airlines' Singapore-Newark service, a 16,700km effort. It's not the trip for your inflight entertainment to go haywire on.
Getting to know: William Nordhaus and Paul Romer
William Nordhaus and Paul Romer are the winners of this year's Nobel prize for economics, which, for the sake of pedantry, it must be clarified is not one of the original Nobel prizes that date back to 1901, but the Sveriges Riksbank Prize created "in memory of Alfred Nobel" in 1969. Nordhaus and Romer are US economists whose research has focused on how the unintended side effects of economic activity may affect growth in the long term. Nordhaus is a fan of carbon taxes, while Romer is more of an innovation subsidies kind of guy. People often think protecting the environment will be so costly and hard, they would prefer to just ignore it, says Romer. But it's not an either-or situation: "We can absolutely make substantial progress protecting the environment and do it without giving up the chance to sustain growth," he says. Now might be a good time to start.
The list: Financial instability
New vulnerabilities have emerged in the global financial system, the International Monetary Fund (IMF) took the time to warn this week. The bad news is that the resilience of the system to absorb shocks is untested since the last big crisis. So what exactly is it worried about?
1. Trade tensions: When trade skirmishes escalate, there are few winners.
2. Emerging economies: Pressure on emerging economies from Brazil to Argentina to Turkey isn’t helping, with any one crisis capable of causing contagion.
3. Political uncertainty: And to think we almost got through this without mentioning Brexit.
4. Monetary tightening: The dialling back of stimulus measures plus rises in interest rates could prompt market turmoil.
5: Debt debt debt: Rising government, household and company debt means any “vulnerabilities” that do turn into problems won’t be very pretty.
