Innovations in Australian Traffic Control
An innovative traffic management system has been implemented in a congested Australian tunnel, utilizing moving lights that drivers are encouraged to follow. This system successfully reduced stop-start traffic incidents by 70%. The mechanism functions by keeping pace with the slowest vehicle within the tunnel, thereby ensuring a consistent flow and preventing the stop-start pattern that typically exacerbates congestion. Anecdotally, drivers find it bothersome when the guiding green lines overtake them, suggesting a competitive element to the regulation.
Sydney Harbor Truck Management Systems
Tunnels in Australia, particularly the Sydney Harbor Tunnel, face unique challenges regarding oversized vehicles. To combat trucks that ignore height restriction warnings and subsequently crash at the entrance, an emergency system deploys a sheet, resembling a waterfall, across the opening. Onto this sheet, lasers project a giant stop sign, making it impossible for the driver to ignore the command and proceed.
- A 17% increase in speed when traffic is present.
- Return to normal speed 95% faster compared to pre-installation times.
- Reduction in vehicle breakdowns due to less frequent heavy braking by large trucks.
This is an absolute nightmare though for a super villain to hack and then set the lights going to 200 mph.
Outback Infrastructure and Road Quizzes
Australian infrastructure extends far beyond tunnels, presenting unique challenges over vast distances, especially in Queensland. To keep truck drivers, particularly those operating massive road trains, engaged during monotonous stretches, authorities have implemented a system of pub quiz questions displayed on roadside signs. These questions cover general knowledge, testing the alertness of drivers traversing the immense landscape.
The Outback Way Builder
The Outback Way, a route spanning over 2,500 km connecting Western Australia to Queensland, is known as the world's longest shortcut. This route was established by Len Beal, a man who spent his life building roads. Remarkably, Beal also undertook training as a bush dentist for his road-building crews, extracting 29 teeth from his team while completing his first major project, the Gun Barrel Highway.
If you break down as well, in 2017, there was a tradesman who crashed his car out in the outback on one of these roads and the closest help he could get was, I believe, 150 km away, which he had to walk.
Golfing on Treeless Links
Another notable Australian feature is the Nullarbor Links, recognized as the world's longest golf course, stretching approximately 850 miles. The name Nullarbor derives from the Latin for 'no trees,' making the area suitable for such an expansive course where players drive significant distances between holes.
Parliamentary Quirks: Tins, Bells, and Banned Words
The New Zealand Parliament employs a unique method for selecting which non-government-sponsored legislation, known as Members Bills, are debated. This process involves drawing numbered tokens, assigned to specific bills, randomly from a biscuit tin that has been in use for three decades. This random selection has led to significant social legislation, such as bills concerning euthanasia and gay marriage, coming up for discussion.
Voting Summons in Westminster
In the UK Parliament, when a vote, or 'division,' is called, a division bell sounds, giving Members of Parliament eight minutes to reach the chamber to register their vote. Due to the sprawling nature of Westminster, these bells are strategically placed across various locations, including local pubs, ensuring MPs are summoned quickly, even if they are away from the main parliamentary buildings.
- "His brains could revolve inside a peanut shell for a thousand years without touching the sides" (1949).
- "Energy of a tired snail returning home from a funeral" (1963).
- "Idle vaporings of a mind diseased" (1946).
The ban lasted less than 24 hours because Australians said no way mate. It was just like are you kidding? That's a national pride that greeting and that word.
Oceanic Mysteries and Lost Artifacts
A bizarre case of extreme object displacement involved a work swipe card belonging to a New Zealand music producer, lost in Wellington in 2003 following a briefcase theft. Thirteen years later, in 2016, the card was discovered by a diver approximately 20 km north of Scott Base in Antarctica, suggesting an incredible journey across thousands of miles of ocean.
The Antarctic Circumpolar Current
Scientists are investigating the origins of the Antarctic Circumpolar Current (ACC), potentially the largest current on Earth, which acts as a buffer between warmer northern waters and the frigid Antarctic region. To date its commencement, researchers analyze chemical signatures found within fossilized fish teeth dating back 50 million years ago.
- Tracking rubber duckies, which have since become collector's items potentially worth around £1,000.
- Monitoring 4.8 million pieces of Lego.
- Tracking 34,000 hockey gloves.
- Tracking thousands of Tommy Pickles cartoon heads.
Would you say it's ironic to run out of fuel when you're on your way to go get fuel?
In a separate incident involving currents, two men from Kiribati drifted 600 km after running out of fuel while attempting to refuel their boat. They eventually reached an atoll where they encountered one man's uncle, who had been missing and presumed drowned for fifty years, having started a new family.
The Mathematical Constant Pi: History and Precision
The mathematical constant Pi, defined as the ratio of a circle's circumference to its diameter, has fascinated scholars for millennia. As early as 1,550 BC, the Rhine Papyrus provided an approximation of Pi as approximately 3.16 by relating the circle's size to a surrounding square.
Milestones in Precision
If it doesn't repeat itself, then that means that all series of numbers are in there somewhere.
- Pi Day, March 14th, coincides with Albert Einstein's birthday.
- The Welsh mathematician William Jones named the constant Pi, possibly referencing periphery.
- Pylish is a constrained writing style where word lengths must match sequential digits of Pi.
- The fastest ocean current and the world's fastest running insect (Australian tiger beetle) travel at the same speed: 5.6 miles hour.
