Days getting shorter, Earth spinning faster these days
6 August 2022
Scientists are perplexed by a slight increase in the speed of the Earth’s rotation in recent years. It’s all the more puzzling because as time has passed, Earth’s spin has been ever so gradually slowing down. This has required leap seconds to be added to clocks from time to time, which are separate to the leap day that needs to be added to the calendar every four years.
Since the first leap second was added in 1972, scientists have added leap seconds every few years. They’re added irregularly because Earth’s rotation is erratic, with intermittent periods of speeding up and slowing down that interrupt the planet’s millions-of-years-long gradual slowdown.
“The rotation rate of Earth is a complicated business. It has to do with exchange of angular momentum between Earth and the atmosphere and the effects of the ocean and the effect of the moon,” Levine says. “You’re not able to predict what’s going to happen very far in the future.”
But in the past decade or so, Earth’s rotational slowdown has … well, slowed down. There hasn’t been a leap second added since 2016, and our planet is currently spinning faster than it has in half a century. Scientists aren’t sure why.
While the speed increase is barely noticeable, the shortest day since the advent of atomic clocks was recorded on Wednesday 29 June 2022, when the day was 1.59 milliseconds shorter than the usual twenty-four hours.
A millisecond or so is small fry though. In the distant past, Earth’s years were made up of four-hundred-and-twenty days, considerably more that the three-hundred-and-sixty-five we’re accustomed to. But it could be worse. If say the Earth spun twice as fast as it presently does, life would be quite different.

A selection of some of the clearest photos taken so far, of Jupiter, the largest planet in the Solar System, by NASA’s Juno spacecraft. This stunning image dates from 2019. Juno has been photographing the gas giant since 2016, on a mission originally expected to last five years. NASA is hopeful however the probe will remain operational until 2025.
More of Juno’s photos can be seen here.

Who are the famous people who make your town notable
3 August 2022
Finnish map designer and geographer Topi Tjukanov has created Notable people, a global map showing the birth places of well-known and famous people. Use your mouse to drag the globe to the desired location, and the scroll wheel to zoom in and out.
Using data from Morgane Laouenan et al., the map is showing birthplaces of the most “notable people” around the world. Data has been processed to show only one person for each unique geographic location with the highest notability rank.
The nearest listed notable person born close to my present location is Australian film and TV actor Steve Bisley, who starred in the original Mad Max movie in 1979.

Somerton Man identified as Carl ‘Charles’ Webb
3 August 2022
Derek Abbott, a professor at the University of Adelaide, claimed last week to have identified the so-called Somerton Man, perhaps bringing a close to one of the most intriguing, and lingering, Australian mysteries of the twentieth century.
In December 1948, the body of a man thought to be about forty, was found at Somerton beach in Adelaide, capital of South Australia. His body showed no sign of trauma. He was not carrying any identification, nor were there missing person reports for anyone matching his description.
In the months following his death, a suitcase containing some of his possessions was located, but offered no clues as to who he was. A scrap of paper, bearing the words tamam shud, was found concealed in clothing the man owned. The fragment was later found to have been torn from a page of a book of poems titled Rubaiyat of Omar Khayyám, originally written in the twelfth century.
It was all enough to send the rumour mill into overdrive. People variously believed Somerton Man to be a spy, a displaced war veteran who’d made his way to Australia, or a jilted lover who’d presumably somehow taken his own life at the beach one night.
South Australian police exhumed Somerton Man’s body in May 2021, to further their investigation, but Abbott had been making progress separately. Working with Colleen Fitzpatrick, an American genealogist, he concluded the man to be Carl “Charles” Webb, an electrical engineer from Melbourne.
While mystery still surrounds the circumstances of his death, Abbott believes Webb may have travelled to Adelaide to see his ex-wife, who moved there after the pair separated several years prior.

Trailer for Blaze a film by Del Kathryn Barton
2 August 2022
Sydney based Australian artist Del Kathryn Barton has turned her hand to filmmaking. Her debut feature Blaze, trailer, which premiered at this year’s Sydney Film Festival, tells the story of a girl, Blaze (Julia Savage), who retreats into an imaginary realm after witnessing an act of violence.
Although she has made a couple of short films previously, Barton is probably best known for winning the Archibald Prize for portraiture in 2008, with her painting You are what is most beautiful about me, a self portrait with Kell and Arella.
Looking at the trailer though, I couldn’t help but thinking Blaze — which opens in Australian cinemas on Thursday 25 August 2022 — is like one of Barton’s artworks come to life.

Belated birthday greetings to George Jetson born 31 July 2022
1 August 2022
I’ve seen a few episodes of The Jetsons, a futuristic carton show that first aired in the 1960s, but had forgotten, or maybe not even known, the setting was 2062. The twenty-fifth century somehow felt more like it. After all, a flying car that compacts down to the size of a briefcase when not in use? Come on, we’ll need a few hundred years to make that a reality.
But according to intenet pundits, George Jetson, husband to Jane, and father of Judy and Elroy, was born in 2022. Some have suggested 31 July as his actual birthday, though series creators have yet to confirm or deny that is the case.

A Voice to Parliament for Indigenous Australians
1 August 2022
The Australian government has undertaken to enshrine an Indigenous Voice to Parliament in the Australian constitution. While it is unclear at this stage exactly what form a Voice to Parliament would take, the purpose is clear:
A Voice to Parliament is a body enshrined in the Constitution that would enable Aboriginal and Torres Strait Islander people to provide advice to the Parliament on policies and projects that impact their lives.
A referendum, a necessary step in the process of altering the constitution, has been proposed for 2023, giving the Australian people the opportunity to have their say in the matter.
An Indigenous Voice to Parliament is seen as an important step in Australia’s ongoing reconciliation with its First Nations people.

Vale Nichelle Nichols AKA Lieutenant Uhura of Star Trek
1 August 2022
American actor Nichelle Nichols, perhaps best known for her role as Lieutenant Uhura, the communications officer of the USS Enterprise, in the original Star Trek TV series and later movies, died aged 89 over the weekend.
Star Trek fans doubtless have many favourite Uhura moments and lines, but this isn’t reality, this is fantasy, from The Search for Spock, the third Star Trek film starring the original cast, has to be up there with the best of them. See also this IMDb photo gallery honouring Nichols’ life and work.
