Knowing draft fate didn’t ease Jamarra’s nerves


Number one draft pick Jamarra Ugle-Hagan already loves the Western Bulldogs.

The Next Generation Academy product was last night snapped up with pick 1 in the National Draft after the Bulldogs matched Adelaide’s bid for the talented forward.

Ugle-Hagan, who grew up a Bombers fan, always knew he would end up at the Whitten Oval and is now thrilled to officially refer to himself a Dogs player having already experienced the culture of the club during his time as an academy prospect.

“As soon as I walked in the door on the first day when I went there, I had Jason Johannisen come up and introduce himself,” he said on SEN Breakfast.

“I expected that the boys were going to be like ‘top dogs’ and stuff, but obviously they’re good blokes in general.

“As soon as you walk in the club, everyone gets to you, even staff.

“I was an Essendon supporter for 17 years, then I walk into the Bulldogs for two weeks, and as soon as I left I’m saying to my parents, ‘bloody hell, I want to go for this club’.

“They’re just that nice. They’re a good club.”

From just outside Warrnambool via Scotch College and the Oakleigh Chargers, Ugle-Hagan has already been on the receiving end of some Bulldogs hospitality.

Without a pair of jeans, he called on the assistance of club captain Marcus Bontempelli to deck him out for the big day.

“I finished up at Scotch College as a boarder, so I moved everything back home,” he explained.

“Everything was at home and the first person I messaged was ‘Bont’. We’re similar height and same shoe size so I thought we’d be the same size pants.

“I messaged him and he said, ‘Come around at 1 o’clock, I’ll give them to you’. I was like, ‘Unreal, I’ll see you soon’.

“Then I went and borrowed his pants.”

Asked if Bontempelli offered up his best set of trousers, Ugle-Hagan felt perhaps the Doggies skipper was keeping his highest quality garb from the club’s newest star-in-the-making.

“I reckon he had better pants to be honest but I can’t complain, he looked after me,” he laughed.

Despite knowing what would eventuate on draft night, Ugle-Hagan admits he was a bundle of nerves beforehand.

“I didn’t expect anything,” he said further.

“I got out of the car with (manager) Robbie (D’Orazio), obviously I was still nervous, I was nearly about to spew.

“I don’t know why. The position I was in, I knew I was going to Footscray, but it was hard to sink in.

“I was nervous before my name got read out but I had my family and mates down at the pub which was unreal.”

Physicists Are Closer to Knowing the Size of a Proton … Sort of


How big is a proton? That might sound like a pretty simple question, but it turned out to have the potential to wreck a lot of modern physics. That’s because different methods of measuring the proton’s charge radius produced results that disagreed—and not just by a little bit. The answers were four standard deviations apart. But now, a new and improved measurement brings them into much closer alignment—though not quite close enough that we can consider the issue resolved.

ARS TECHNICA

This story originally appeared on Ars Technica, a trusted source for technology news, tech policy analysis, reviews, and more. Ars is owned by WIRED’s parent company, Condé Nast.

There are a couple of different ways to measure a proton’s charge radius. One is to bounce other charged particles off the proton and infer its size by measuring the deflections. Another is to look at how the proton’s charge influences the behavior of an electron orbiting it in a hydrogen atom, which consists of only a single proton and electron. The energy difference between different orbitals is the product of the proton’s charge radius. And, if an electron transitions from one orbital to another, it’ll emit (or absorb) a photon with an energy that corresponds to that difference. Measure the photon and you can work back to the energy difference, and thus the proton’s charge radius.

(The actual wavelength depends on both the charge radius and a physical constant, so you actually need to measure the wavelengths of two transitions to get values for both the charge radius and the physical constant. But for the purposes of this article, we’ll just focus on one measurement.)

A rough agreement between these two methods once seemed to leave physics in good shape. But then physicists went and did something funny: They replaced the electron with its heavier and somewhat unstable equivalent, the muon. According to what we understand of physics, the muon should behave just like the electron except for the mass difference. So, if you can measure the muon orbiting a proton in the brief flash of time before it decays, you should be able to produce the same value for the proton’s charge radius.

Naturally, it produced a different value. And the difference was large enough that a simple experimental error was unlikely to account for it.

If the measurements really were different, then that would indicate a serious flaw in our understanding of physics. If the muon and electron don’t behave equivalently, then quantum chromodynamics, a major theory in physics, is irretrievably broken in some way. And having a broken theory is something that makes physicists very excited.

The new work is largely an improved version of past experiments in that it measures a specific orbital transition in standard hydrogen composed of an electron and a proton. To begin with, the hydrogen itself was brought to a very low temperature by passing it through an extremely cold metal nozzle on its way into the vacuum container where the measurements were made. This limits the impact of thermal noise on the measurements.

The second improvement is that the researchers worked in the ultraviolet part of the spectrum, where shorter wavelengths helped improve the precision. They measured the wavelength of the photons emitted by the hydrogen atoms using what’s called a frequency comb, which produces photons at an evenly spaced series of wavelengths that act a bit like the marks on a ruler. All of this helped measure the orbital transition with a precision that was 20 times more accurate than the team’s earlier effort.

The result the researchers get disagrees with earlier measurements of normal hydrogen (though not a more recent one). And it’s much, much closer to the measurements made using muons orbiting protons. So, from the perspective of quantum mechanics being accurate, this is good news.

But not great news, since the two results are still outside of each other’s error bars. Part of the problem there is that the added mass of the muon makes the error bars on those experiments extremely small. That makes it very difficult for any results obtained with a normal electron to be consistent with the muon results without completely overlapping them. The authors acknowledge that the difference is likely to just be errors that are unaccounted for, citing the prospect of “systematic effects in either (or both) of these measurements.” These effects could broaden the uncertainty enough to allow overlap.

Son who grew up not knowing his father was an undercover police officer receives compensation – Channel 4 News


A man who grew up not knowing that his father was actually an undercover policeman, spying on his mother, has received substantial damages for the emotional trauma it’s caused.

Bob Lambert fathered the child during a relationship with an animal rights activist.

But Mr Lambert wasn’t an activist as he claimed, he was a Metropolitan Police Officer on a covert operation.

The Met Police have apologised unreservedly.

Rebecca Judd reveals Qantas pyjamas as secret to knowing if someone is rich


Rebecca Judd has revealed her bedroom secret to knowing whether someone is rich.

According to the popular footy WAG, the coveted Qantas PJs given out to business and first class passengers are a telltale sign that someone is cashed up.

Speaking on her radio show 3PM Pick-Up, the 37-year-old said she saw people wearing them in rather unusual locations.

“I know of someone who wears them to school pick up. Other people wear them as their spray tanning uniform,” she said.

It comes as no surprise that the former model owns a few pairs of the pyjamas herself from frequent business class flights.

“I have lots of frequent flyer points. So I fly business a lot and get a lot of these pyjamas on the points,” Judd said.

She added that it was difficult to go back to economy after flying business class.

“Once you do. You can never go back,” she said.

“I think ignorance is bliss there. Don’t do it as it gets expensive.”

With all international flights and many domestic flights suspended, Qantas had excess stock of their highly sought after grey jammies and made them available for purchase in their care packs.

A few hours after the care packs became available for purchase, all 10,000 sold out with fans rushing to get their hands on the exclusive items.

The care packages came in at a bargain $25 — or 4350 Qantas points — and included other Aussie favourites like Tim Tams, tea and a Qantas-branded amenity kit.

In a statement a Qantas spokesperson said it was better to have people enjoying the PJs rather than having them sit in storage.

Hydro Tasmania subsidiary pushed ahead with dam project knowing of concerns


Hydro Tasmania’s consulting business pushed ahead with work on a northern Ugandan hydropower project despite acknowledging ongoing community concerns, reports of legal proceedings and corruption, technical issues, and poor workmanship, according to documents.

A worker also later died on-site in a shooting incident, according to a local police report.

Emails, briefing reports and screening summaries released to the Tasmanian Greens show Entura initially deemed the project “high risk”, but downgraded that to “medium” after a screening process, while acknowledging ongoing concerns with local community relations and environmental management.

Entura was contracted by PowerChina Huadong to provide advisory services for the Karuma hydropower project in March 2017.

Entura was effectively a sub-contractor on the project, managing a range of project stakeholders, undertaking design reviews and advising on compliance with international standards.

After questioning Hydro Tasmania in 2018 over reports of unsafe working conditions and a death at the site, Greens MP Rosalie Woodruff received partially-redacted documents showing Entura signed up to the project despite being aware of numerous issues.

“The obvious red flag is that Hydro Tasmania identified levels of community protest and outrage, they identified human rights issues, and they identified impacts on communities,” Dr Woodruff said.

One of the documents is an email discussing a potential site visit for two staff to the Karuma project in October 2016.

Eighteen Entura staff worked on the project for an average of 18 days each, between March 2017 and September 2019.

Five of those people worked at the construction site in Uganda, which was manned by security and defence force soldiers.

Risk downgraded after mitigation assessment

Entura conducted a sustainability screening process in November 2016, which initially rated the environmental and social risk of the project as “high”.

That means it included activities with “potential significant, diverse, irreversible and/or unprecedented adverse social and environmental risks and impacts” and/or “may, or has, raised significant concerns among potentially affected communities and individuals”.

It noted numerous reports of technical and governance issues, widely reported issues with construction, community concerns about lack of consultation and poor compensation, and reports of numerous legal proceedings.

As part of that project screening, Entura produced a “summary against sustainability code” document, which was a spreadsheet listing the risks, how they could be mitigated and what the residual risk would then be.

The document shows Entura downgraded the residual risk of the overall project after mitigation measures to “medium”.

A summary of the human rights issues, impact on communities and level of community outrage has been redacted but those elements are labelled “high risk”, even after mitigation.

Regarding how the community issues could be mitigated, the document states that Entura’s confined role in the project offers “limited scope to reduce community risk”.

The summary proposes the “high” risk of numerous technical issues could be downgraded to “medium” by ensuring “all designs reviewed by Entura were fit for purpose and met appropriate standards”.

After a site visit, comments were that onsite safety appeared to be adequate and the overall quality of the project was expected to be fit for purpose.

Before signing the contract with PowerChina, Entura also completed a sustainability screening of Uganda as a new market, rating it as “medium risk” and acknowledging the country had a poor record of human rights management.

“That sends a pretty strong signal to companies like PowerChina that regardless of what they do in countries, Entura is going to help them anyway.”

In a statement, an Entura spokesman said it screened all projects prior to signing agreements, and evaluated them against Hydro Tasmania’s sustainability code, which included social, environmental, economic and reputational criteria.

“Since November 2016, Entura has used additional criteria in its sustainability screening process,” the statement said.

Working relationship with PowerChina influenced decision to proceed

In an internal briefing report, Entura said it made the decision to proceed with the project for reasons including that the project was already in its third year of construction and that any social issues associated with resettlement had already occurred.

It said a site visit indicated no obvious safety concerns.

Entura also listed the importance of its relationship with PowerChina as a reason for proceeding with consulting on the project.

In a statement, an Entura spokesman said the business had proceeded with the work in order to share the benefits of clean renewable energy with the developing world.

“We determined that while Entura’s involvement on the Karuma project was minor, within the limitations of our role, we had a positive influence on the project’s overall design, safety and sustainability,” the statement said.

Dr Woodruff said there was no justification for a public Tasmanian business to be involved in the Karuma project.

“But fundamentally, if it’s a dam that’s based on human rights abuses, legal fights with communities where land has been taken from them, and environmental issues, this is not something that Tasmanian people want their public money put towards.”

Entura unaware of 2018 shooting death

The documents released to the Greens include a police report into an incident in June 2018, where one worker died as a result of shots fired during a scuffle between workers and soldiers.

In an internal briefing report from December 2018, Entura said the fatal incident occurred after its second-last visit to the site, and on the final visit in September 2018 there was no mention of the incident.

The report states that Entura was unaware of the shooting incident until Dr Woodruff raised the issue.

Entura had been informed about the death of another worker due to a hippopotamus attack outside the compound.

A spokesman said the business had also been made aware of a worker who took their own life.

There are some media reports of other deaths on site at the Karuma project, but these are not referenced in any of the information released by Entura.

The ABC has contacted PowerChina Huadong for comment.

Hydro Tasmania ‘obstructing our efforts’: Greens

The Greens sought access to correspondence regarding the Karuma hydropower project through Tasmania’s Right to Information Act (RTI) process in December 2018.

After some back and forth, Hydro Tasmania provided the partially redacted documents to Dr Woodruff in March 2019.

However, it later became apparent that the RTI response had not been issued by a delegated officer as required, and the Greens were therefore unable to progress their request for an Ombudsman’s review.

“Having a public entity obstructing the release of information in clear defiance of statutory deadlines is totally unacceptable.”

The Entura spokesman said Hydro Tasmania and Entura did not agree with Dr Woodruff’s characterisation, and had corrected the delegation error recently.

“[The operation has] also provided a process that actually speeds up the subsequent external review requested by Dr Woodruff,” he said.
