David Cameron responds to rioting, promises changes on policing

Saturday, August 13, 2011

British Prime Minister David Cameron has stated that a change in police strategy is appropriate following what many feel to be an inadequate response to the rioting that has overrun many cities across England. Riots started in Tottenham on Saturday night after the fatal shooting by police of Mark Duggan, a 29-year-old taxi driver who the Independent Police Complaints Commission state was in possession of a handgun, but did not fire it.

During the Parliamentary debate on the riots, David Milliband, the Labour leader, called on Cameron to reconsider cuts to police budgets. Chancellor of the Exchequer George Osborne described the communities where the rioting occurred as being “left behind” and “cut-off from the economic life-blood of the rest of the country”, and called for solutions to the “deep-seated social problems”

One avenue the Prime Minister is said to be considering is changing regulations on social media services like Twitter, Facebook and BlackBerry Messenger, the latter being used to communicate between groups of rioters. The Open Rights Group and Big Brother Watch came out in opposition to any plans to restrict communication using social media, with Jim Killock of the Open Rights Group warning that such regulation would be abused by the police and private companies.

In Southampton, England, three people were arrested by police for the suspicion of using Twitter or BlackBerry Messenger to encourage the rioting. The government is “working with the police, the intelligence services and industry to look at whether it would be right to stop people communicating via these Web sites and services when we know they are plotting violence, disorder and criminality,” said Cameron.

The Prime Minister also announced that he would consider using the army to support the police in controlling future rioting, and also that he would consult with William J. Bratton, CBE, who had been the chief of police in Los Angeles and a police commissioner in New York City and Boston. Bratton is quoted as saying that arrests are not the only way to solve societal problems which lead to rioting and unrest: “You can’t arrest your way out of the problem.”

U.S. judge orders release of President Trump’s tax records, appeals court issues delay

Thursday, October 10, 2019

On Monday, United States District Court Judge Victor Marrero issued a ruling against President Donald Trump finding that New York City prosecutors could view his tax records after a subpoena issued by a grand jury. The Manhattan district attorney’s office is investigating Trump over alleged hush money paid to two women with whom he has been alleged to have had affairs. Such payments could be considered bribery. President Trump sued Manhattan District Attorney Cyrus R. Vance, Jr. and his own tax preparer Mazars USA to block the release of eight years of tax returns to the grand jury, but Judge Marrero dismissed the president’s lawsuit. The president’s legal team appealed the decision to the Second Circuit Court of Appeals, which issued an administrative stay to Marrero’s order about an hour and a half after the district court ruling.

The appeals court ruling placed a stay on the district court’s ruling until it hears arguments from the president’s lawyers and District Attorney Vance’s office. According to a court clerk, arguments in the case would be scheduled as soon as the week of October 21, with briefs from both parties due in the intervening time until then.

Trump had asked the United States District Court for the Southern District of New York intervene in a New York City criminal proceeding, in which a subpoena had been issued to Trump’s tax preparer. He sought such intervention to prevent Mazars from releasing his tax returns, arguing that, as president, he should be immune from prosecution, and that, by extension, his tax preparer, Mazars USA, could likewise be exempt from investigation. Marrero rejected this argument:

The notion of federal supremacy and presidential immunity from judicial process that the President here invokes, unqualified and boundless in its reach as described above, cuts across the grain of […] constitutional precedents. It also ignores the analytic framework that the Supreme Court has counseled should guide review of presidential claims of immunity from judicial process. Of equal fundamental concern, the President’s claim would tread upon principles of federalism and comity that form essential components of our constitutional structure and the federal/state balance of government powers and functions. Bared to its core, the proposition the President advances reduces to the very notion that the Founders rejected at the inception of the Republic, and that the Supreme Court has since unequivocally repudiated: that a constitutional domain exists in this country in which not only the President, but, derivatively, relatives and persons and business entities associated with him in potentially unlawful private activities, are in fact above the law.

Because this Court finds aspects of such a doctrine repugnant to the nation’s governmental structure and constitutional values, and for reasons further stated below, it ABSTAINS from adjudicating this dispute and DISMISSES the President’s suit.

Following Marrero’s order, the appeals court issued a stay, delaying Mazars’ compliance with the subpoena until it could review the case.

Trump responded to the ruling via Twitter, attacking the subpoena as a political strategy: “The Radical Left Democrats have failed on all fronts, so now they are pushing local New York City and State Democrat prosecutors to go get President Trump.”

The Manhattan district attorney’s office began its probe into Trump’s financial affairs after his former lawyer Michael Cohen was convicted of federal campaign finance law violations connected to payments made to porn actress Stormy Daniels and former Playboy model Karen McDougal to remain silent about alleged affairs with Trump. Cohen is serving a three-year-long prison sentence.

Trump has admitted to ordering the payments, according to prosecutors, but the U.S. Justice Department maintains a policy of not charging the sitting president with crimes.

In recent United States history, it has been customary, but voluntary, for presidential candidates to release their tax returns when running for office. Trump was the first president to refuse to do so since 1976. Trump has cited an Internal Revenue Service audit as prohibiting him from releasing them. The president has a lawsuit to prevent a New York State law from allowing the House of Representatives’ Committee on Ways and Means from gaining access to his records.

The Sdvosb In Norfolk, Virginia Can Get Your Vessel Inspection Ready

April, 2015 byadmin

Were you in any of the armed services, were injured as a result of being in that particular branch, and now you own a small business? If so, you are part of a group of businesses known as service disabled veteran-owned small businesses (SDVOSB). There is an SDVOSB in Norfolk Virginia who supplies shipboard repair merchandise and consultation services for customers in need. In case you are unclear on exactly what constitutes an SDVOSB organization, here is a little information that may aid you in wanting to be a part of supporting the American military.

An SDVOSB organization is one that is owned and controlled by one or more veterans who are service-disabled. On top of that, the organization must be considered a small business according to the guidelines of the Small Business Administration. It was in October of 2004 when the President of the United States mandated that federal agencies must provide to SDVOSB organizations the opportunity to be awarded federal contracts and subcontracts. Federal agencies have a contracting target to grant at least three percent of prime contracts organizations that are SDVOSBs.

With that understanding, you can understand what you can do to be of service to these type of organizations. Coronado DC is an SDVOSB organization that provides shipboard repair services for customers looking for supplies. Just about any and every part you would need for a ship can be found at the Norfolk distribution center. Stainless steel bolts, deck drains, and rack repair parts are all part of the inventory you could find. The business also offers discount pricing to those with government purchase cards.

Business customers can also take advantage of the consultation services for ship owners, such as INSURV inspections. Experienced staff members will come and thoroughly go over your vessel with a fine-toothed comb to ensure your ship is inspection ready. Some of the staff members formerly served upon the same type of vessels when they were in service and knew what is being looked for in INSURV inspections. If you need supplies for your ship or need to get it inspection-ready, call upon the SDVOSB in Norfolk Virginia who can help you.

Recall of Thomas the Tank Engine toys due to lead-paint fears

Thursday, June 21, 2007

A recall issued last week for Thomas the Tank Engine toys made in China and containing lead-based paint, is the latest scare for consumers, and follows recent scandals involving Chinese-made pet food, pharmaceuticals, toothpaste and other toys, The New York Times has reported in a series of articles.

Last week, RC2, a U.S. toy company based in Oak Brook, Illinois, issued a recall for its popular wooden “Thomas the Tank Engine and Friends” train sets. The recall involved 1.5 million “Thomas Wooden Railway” vehicles and train sets sold at toy stores and various retailers across the U.S. from January 2005 through June 2007.

A subsequent recall has been issued in the United Kingdom, where Thomas the Tank Engine was originated in the 1940s as a character in a children’s story by the Reverend W.V. Awdry. Around 70,000 toys are involved in the U.K. recall, according to The Guardian.

“RC2 has determined that the surface paints on the recalled products contain lead. Lead is toxic if ingested by young children and can cause adverse health effects,” the Consumer Product Safety Commission said in a press release dated June 13. “Consumers should take the recalled toys away from young children immediately and contact RC2 Corp. for a replacement toy,” the commission said.

Those “adverse health effects” could include brain and nerve damage, especially in young children, as well as blood and brain disorders. Severe lead poisoning causes vomiting, diarrhea, convulsions, anemia, loss of appetite, headaches and in particularly high doses, coma and death.

In an article on Monday, The New York Times reported that recalls have been issued for 24 different toys in the U.S. in the past year, and every one of them was made in China. According to the Toy Industry Association, toys made in China account for around 70 percent to 80 percent of all the toys sold in the U.S., The Times said.

“These are items that children are supposed to be playing with,” Prescott Carlson was quoted as saying by The Times. Carlson is a co-founder of a child-safety website called Imperfect Parent, which tracks recalls of toys and other baby products. “It should be at a point where companies in the United States that are importing these items are held liable,” Carlson said.

RC2 would not comment to The Times, and a Consumer Product Safety Commission spokesman would not say how long ago the problem with the lead paint was discovered.

For a follow-up article on Tuesday, The Times visited a factory in Dongguan, in China’s Guangdong province, where the “Thomas and Friends” toys are made. The paper interviewed workers and took photos on the factory floor.

“You’re intruding,” a factory manager identified only as Zhong was quoted as telling the reporters. “Tell me, why exactly are you here?”

During the visit, a reporter, translator and a photographer were detained by factory officials, and released a day later after local police and government officials intervened.

The factory also produces other toys for RC2, including toy John Deere trucks, NASCAR racing models and M&M’s cars, The Times said. RC2 makes the toys under licenses from various companies. The “Thomas and Friends” toys are made under license from Hit Entertainment, which owns the “Thomas” brand.

According to RC2, items in the “Thomas and Friends” recall are:

  • Red James Engine & Red James’ # 5 Coal Tender
  • Red Lights & Sounds James Engine & Red James’ #5
  • Lights & Sounds Coal Tender
  • James with Team Colors Engine & James with Team Colors *#5 Coal Tender
  • Red Skarloey Engine
  • Brown & Yellow Old Slow Coach
  • Red Hook & Ladder Truck & Red Water Tanker Truck
  • Red Musical Caboose
  • Red Sodor Line Caboose
  • Red Coal Car labeled “2006 Day Out With Thomas” on the Side
  • Red Baggage Car
  • Red Holiday Caboose
  • Red “Sodor Mail” Car
  • Red Fire Brigade Truck
  • Red Fire Brigade Train
  • Deluxe Sodor Fire Station
  • Red Coal Car
  • Yellow Box Car
  • Red Stop Sign
  • Yellow Railroad Crossing Sign
  • Yellow “Sodor Cargo Company” Cargo Piece
  • Smelting Yard
  • Ice Cream Factory

Toys listed that are marked with codes containing “WJ” or “AZ” are not included in the recall.

Earlier, RC2 said that customers would have to cover shipping costs to return the toys to the company. It later agreed to cover postage after angry complaints by parents, The Times said in an article yesterday. Refunds will take about two months.

Interview with Ton Roosendaal about Elephants Dream and free content movies

Sunday, May 21, 2006

Three days after the Internet release of the free content 3D short Elephants Dream (see Wikinews coverage), we exchanged e-mails with Ton Roosendaal about the reaction to the film, open source filmmaking, and the changes to Blender that resulted from the production. Ton Roosendaal is the lead developer of the Blender 3D rendering and modelling software that was used for the movie. He is also the chairman of the Blender Foundation, a non-profit organization which was formed in support of the software and projects like Elephants Dream.

How much money did the Blender Foundation spend on producing the movie? Has the money been fully recouped by DVD orders and donations?

We still have to finish the final bookkeeping for this project. It has been executed in co-production with the Netherlands Media Art Institute, and we each had our own internal budgeting for the project. When you exclude expenses of pre-production and producer personnel, the total budget was about 120,000 €, of which we covered half. Our contribution was roughly covered half by the DVD sales, and half by European Union support (http://www.uni-verse.org consortium).

One of the most common criticisms of CGI films is focus on technology over content. For instance, Final Fantasy: The Spirits Within flopped with audiences, in spite of being an undisputed technical milestone. I’ve seen many reviews that criticized the plot of “Elephants Dream” as too bizarre or confusing. In retrospect, are you happy with the story development process?

Haha, I knew the story and plot would get a mixed acclaim. There’s a couple of reasons I’d like to mention for it.

First of all; the criticism resembles how people witness Blender itself, too. Many people expect that Free Software is an easy accessible mass audience product. We get a lot of complaints by non-artists that they can’t get into the software easily, whilst the complexity of commercial products like Maya or Houdini is perceived as a confirmation of its “quality”. Apparently an Open Movie created similar expectations with the audience.

Luckily we also got many positive reviews of the artistic result of the movie. It is quite abstract, but definitely has many layers of information, inspiring many of the viewers to see relevant real life messages hidden here.

For this project we’ve teamed up with the Netherlands Media Art Institute, internationally renowned as a resource for video art. So for Elephants Dream, we’ve had the luxury to challenge ourselves to create real independent artistic content as well. The artists had a lot of freedom from the start; they were responsible for the concept, story and creative development of the entire movie. This has resulted in a lot of quite personal choices, based on what the artists liked to do themselves. I really cherish such an approach, it has resulted in a very motivated team working crazy hours the last months to get it all realized.

But, most importantly; the main target of our project was not only to create a 3D movie short, but to experiment with ways to improve the efficiency and quality of open source development. On this aspect only, this project was just a huge success, and the main reason for our sponsors (the DVD pre-sale) to support it. I know they might have liked a cartoonish funny movie with furry animals better, but for that you get already pretty well served by the bigger 3D animation studios. 🙂

I’m the first to admit that – looking back especially – certain aspects worked out quite weakly; there’s loose ends and questionable decisions, especially in story development and continuity. That’s just the risk of doing experiments, and nothing I regret really. The five artists from our user community who were invited to make the movie were young people with no professional background in filmmaking. Their personal incentive to participate in this project was also to learn from it, and to create a good portfolio for their future career. I’ve witnessed them grow in competence in the past year enormously, something I’m incredibly proud of.

On the technical level, the only major criticism I’ve seen of “Elephants Dream” is the character animation, especially in the opening scene — many reviewers felt that the movements seemed a bit unnatural. Do you agree with these criticisms? If so, what do you think can be done to improve on that level?

Yeah, the challenge the artists set themselves – to use quite realistic personages – is also something that easily works against you. In many animation movies they introduce characters in the beginning in a way you get used to their specific characteristic movements, so you accept a certain level of non-realism easily. (Check the weird walk cycles in The Incredibles for example). Another aspect is that we’ve started work on the first scenes, and ended with the last scenes. I can clearly see the animation quality increase, and that whilst the ending scenes were done in much less time due to time constraints.

We also didn’t schedule to do 9.5 minutes of animation either…. Originally it was more like 6. But, it’s always easier to look back to define the right decisions, eh? 🙂

I’m very happy with the reviews we got so far; luckily the movie was perceived as a professional quality product, and reviewed based on comparisons with what the big studios come up with. Even when we couldn’t satisfy all these quality demands, it has luckily not been branded as a pathetic presumptuous attempt by amateurs!

Do you think there is hope for a full-length open movie project in the near future? Would the Blender Foundation be interested in such a project, or do you intend to continue focusing mainly on shorts?

I’d like to wait a little while with defining what a next project would look like. Given the constraints of “organizing projects to improve open source development”, we might have not much choice either. It would probably mean to work with a new team each time, so most likely be based on shorts only. On the other hand, there’s also clear signals that this approach works well, and creates excitement and involvement of a lot of people, also from producers and sponsors. That might enable us to set up a next project based on larger targets. For a full-length feature film however, we should involve a sufficient amount of experienced film makers as well, and/or invite the first team to participate again. That would put a lot of pressure on the required budget…. You can’t do that based on a 1000 DVD pre-sale target. Would more be like 20,000 or so…. 🙂

How did the process of making the movie feed back into the development of Blender? Are there major technical changes that were made only or primarily because of the film?

Already during the pre-production phase the artists have defined the key targets for Blender development. This then was coordinated with the online development community too. I’ve done the most crucial (re-)development mostly myself, though. Especially on the character animation tools, on the rendering pipeline and compositing tools.

It is especially the latter I’m most satisfied with. In 3D movie production the compositing stage creates a giant content bottleneck. By transparently integrating this in our render-pipeline, a very efficient workflow has been achieved. And, not to forget, Blender now also offers the first production-level open source compositor on the market!

The current summary you can find in our work-in-progress release notes.

What are the key technical features in Blender you want to add or improve for future movie projects?

Depends on what the movie is about! There’s always hundreds of features you can work on. However, we’ll have to work on that anyway, movie project or not. There’s a lot of professionals using Blender now, and they can’t wait for the Blender Foundation to do movies! Look at this studio for example:http://www.plumiferos.com/

I read that at least one proprietary software package, Reaktor, was used for the sound effects. Is this because no equivalent free software solution exists yet? Will future projects have a “free software only” policy?

We’ve limited the “Open Source tools” requirement to our own Studio Orange only. That was what we could keep in control at least, and I can tell you it was not always easy even… 🙂

For sound and music we’ve decided from the beginning to seek an external sponsor. We have chosen to work with the best quality studio and composer we could find, preferably using open source, but not as a prerequisite.

My own competence is solely within the CG [computer graphics, Ed.] side of movie making. When it comes to music editing, or video encoding and DVD authoring, I could only decide to choose to work with external parties with proven competences in that area. I have to be practical in projects like this, especially to ensure it will be realized.

Hopefully, now we’ve got so much attention world wide, we can involve more non-CG open source next time, too. I will definitely strive for the maximum here, but it will fully depend on the amount of professional support we can get.

Blender itself was originally closed source freeware, until it was “liberated” through a fundraising campaign. If you could choose one proprietary application to “set free” where such a goal could be realistically achieved, which one would it be?

Well, the “realistically achieved” demand makes it quite difficult. 🙂 Looking back at similar cases, like Mozilla and OpenOffice.org, it was always very circumstantial. It just happens sometimes, you can’t organize something like this to happen in advance. The only common denominator is “a company in troubles”… so, who’s in trouble now?

What is your personal favorite computer-animated full-length film?

Uuuh… that differs every week! Probably Ice Age (the first one). Mostly because they didn’t overdo showcasing 3D technology so much, but created truly adorable characters and great funny gags.

David S. Touretzky discusses Scientology, Anonymous and Tom Cruise

Wednesday, February 6, 2008

David S. Touretzky, prominent free speech activist and critic of Scientology, discussed his opinions on the recent Internet backlash against the Church of Scientology in an interview with former Scientologist and Wikinews reporter Nicholas Turnbull. The recent conflict on the Internet between critics of Scientology and the Church has been spurred on in declarations by a nebulous Internet entity using the name Anonymous that the Church of Scientology “will be destroyed”. Anonymous has directed recent protests at Scientology centres across the world, which have attracted significant numbers of individuals supporting the cause. In recent e-mail correspondence with Wikinews, a representative of the Church of Scientology declared that the Church considers the activities of Anonymous to be illegal, and that Anonymous “will be handled and stopped”.

Touretzky, a research professor in artificial intelligence and computational neuroscience at Carnegie Mellon University, has been a prominent critic of the Church of Scientology since mid-1995, and has been protesting against Scientology vociferously since then; he has also run websites that publish material that Scientology wishes to keep suppressed from the public eye, such as extracts from Scientology’s formerly-confidential Operating Thetan (OT) materials. Touretzky views the actions of the Church of Scientology as being “a threat to free speech”, and has endured harassment by the Church of Scientology for his activities.

The Church of Scientology continues to suffer damage to its public reputation through increased exposure on the Internet and vocal protests by Scientology critics such as Prof. Touretzky. A recent event that focused intense attention on Scientology’s totalitarian attitude was the leak of an internal Church of Scientology propaganda video to the Internet video sharing site YouTube, in which celebrity Scientologist Tom Cruise spoke heavily in Scientology’s jargon and stated that that “we [Scientology] are the authorities” on resolving the difficulties of humanity. The declaration of war by Anonymous followed shortly after this leak, in the form of a video posted to the Internet.

The ongoing dispute, cast by some as Scientology versus the Internet, brought Scientology terms such as “SP” (Suppressive Person, an enemy of Scientology) and “KSW” (Keeping Scientology Working) into general usage by non-Scientologists from the late 1990s onwards; increased attention has been drawn to Scientology by the release of the Cruise video in addition to media coverage. This focus has caused an even greater propagation of these terms across the outside world, as Touretzky comments in the interview.

Wikinews asked Prof. Touretzky about the impact that the activities of Anonymous will have on Scientology, the public relations effect of the Tom Cruise video, the recent departure of individuals from the Church of Scientology’s executive management, the strategies that Anonymous will employ and Touretzky’s experiences of picketing the Church.

Term Life Insurance Quotes How To Compare Them

By David J. Livingston

If you are looking to get a term life policy, your first step is to get term life insurance quotes, as many of them as possible. Getting the quotes is just the first step. That means your actual shopping i.e. clever shopping involves comparing the various different quotes you get from the different providers on different websites. These days it is easy to get instant term life insurance quotes and compare them in one place with the online services provided by many health care or other websites.

While getting the quotes and looking at them in one place is easy, comparing and choosing is definitely not that easy task. This is because a lower premium or more inclusions or heavy coverage does not indicate the best policy.

Term life policy is a coverage option that insures an individual for a set time period or term. If the policyholder dies while the policy is still in term, the death benefits are paid to the beneficiaries. Otherwise the policy just ceases to exist at the end of the term. Most companies let the policyholder to renew the term without medical examination but after adjusting the term for age. So getting the right company and the right policy at the outset is very important so that you can have stress free life coverage for life.

To compare quotes you need to get many quotes. Few things that you need to consider while getting quotes are

[youtube]http://www.youtube.com/watch?v=X8CyyBiueoo[/youtube]

1. Your annual income

2. Outstanding debt

3. Lifestyle expenses

4. Savings and investments

These details help determine the amount of coverage you would need to purchase. Roughly you would need about five to eight times your living needs. Based on this coverage amount required, your age, term of cover and your health the premium will be fixed. So the first thing you would have to compare is the coverage offered in the different quotes.

Some companies may offer low insurance rates but at the same time they will also offer low coverage. So you need to decide on what you are looking to compromise on. Low rate and low coverage is not really a great deal. Next compare the associated term of the policy across the quotes. A short-term policy should have lower insurance rate when compared to the long-term policy. So this would surely affect your premium and if you miss this you might choose a policy for lower premiums just to find out later that you have chosen a short-term policy when you actually needed a longer policy.

Next compare the different conditions and underwriting policies of the different providers. Some might require medical exams; some might have specific policy with regards to the death benefit; some may have a specific way of dealing with accidental death, etc. Make sure you explore what the various inclusions and exclusions of each policy. Then you can compare the costs i.e. the premium that you will be paying the company on the monthly basis or yearly basis. Check to see under what rate class each of the companies has rated you. In one you would be in the preferred class in another you might be in the standard class etc. The rate class determines your premium.

While comparing the quotes you should also check for the reputation of each of the providers. Even if a company offers a higher insurance rate, if it has a better reputation compared to another that offers lower rates, you are better off picking the more reputed one. This is because with reputed companies you have more surety of payouts. Also make sure that the company has no complaints and if there were any look to see how they mitigated those complaints. You can take the assistance of the local Better Business Bureau and the State Department of Insurance in checking the reputation of the companies. At any cost you need a reliable provider. In fact you are entrusting them with the money that your family will need after your time.

Wikinews interviews Dr. Michael Mazilu on creating world’s fastest spinning manmade object

Friday, September 13, 2013

A study in Nature Communications last month reported the University of St Andrews near Edinburgh, Scotland was briefly home to the world’s fastest spinning manmade object. Physicists accelerated a microscopic sphere of atoms to 600 million revolutions per minute; it then, according to press coverage, disintegrated. Wikinews contacted the team to learn more.

The experiment was designed to explore the boundary between conventional physics, which applies to larger objects, and quantum physics, which applies only to extremely small objects. Subatomic particles obey a very different set of rules than the items we see every day, but the behaviour of particles at just above quantum levels remains enigmatic.

The team wanted to expand upon research using single atoms or molecules, instead constructing a four-micrometre thick sphere of calcium carbonate, in a crystaline form called vaterite, in a bid to examine systems containing over a million atoms. The ball was so small it could be manipulated using lasers; light beams exert a force called radiation pressure.

With the ball held within a vacuum by a laser trap, the scientists were able to apply a twisting force through the light’s polarisation (orientation) as it passed through the ball. The vacuum eliminated air resistance so that scientists could look for evidence of quantum friction, a proposed force that slows spinning particles without external assistance.

The spinning sphere turned into a miniature gyroscope, stabilising itself. The ball cooled as it span to ?233°C (?387°F, 40 Kelvin).

The research was carried out by Dr. Yoshihiki Arita, Dr. Michael Mazilu, and Professor Kishan Dholakia. Wikinews was able to ask Mazilu some questions about his research.

((Wikinews)) What first got you interested in researching quantum friction?

Michael Mazilu: The fundamental aspect that raised our interest is the mechanism that stops an object [rotating] infinitely fast in absence of friction. Quantum friction is one possible but debatable mechanism that will ultimately limit the rotation rate. One can also imagine other interesting mechanisms and we hope that future experiments will be able to conclusively distinguish between them.

((WN)) Press coverage has focused on the fact this is the fastest spinning manmade object ever created, but the aim of the experiment was to research quantum physics. How did you end up with this unusual record — was it by accident?

MM: From the beginning we wanted to go for a very fast rotating sphere to test the limits of transfer of angular momentum of light. The motivation was to explore if we can see [if] any anomaly arose as we rotated the particle faster and faster. The hope was to develop an experimental platform that would allow testing the boundary between classical and quantum physics. That this worked better than expected was a happy accident.

((WN)) How was the sphere manufactured, and how long did it take?

MM: The spheres are produced by mixing three chemical compounds together (CaCl2, MgSO4 and K2CO3) until the mixture becomes transparent. This happens in about 5 to 10 minutes and results in birefringent spherical vaterite crystals of 4.4 micrometer in diameter.

((WN)) How long did the sphere take to reach 600 million revs per minute and break up?

MM: The whole process takes about 10–20 minutes. It all depends on how fast we evacuate the vacuum chamber. If we do it too fast we risk [losing] the micro-gyroscope from the trap. With regard to the sphere breaking up: This is a working hypothesis that we are not able to prove yet. What we observe is that the signal corresponding to the rotating sphere disappears at 600 million RPM. We need further measures to verify if the sphere breaks up or if its motion is perturbed and it escapes in some slingshot or other motion.

((WN)) Could the high speeds attained be taken as evidence against quantum friction, as the sphere simply kept getting faster until it broke apart?

MM: This is a very interesting question. The particle keeps getting faster and faster until the signal disappears, however, just before this happens we observe that the slope of the acceleration changes. This could be seen as a signature of “quantum friction” but we need to look more closely. Alternatively, it might be a consequence of the sphere deforming at such high rotation rates.

((WN)) The experiment failed to conclusively prove quantum friction, but did it provide any evidence to support the theory?

MM: The main goal of the experiment was not to prove or disprove quantum friction but to develop a tool that might be useful to carry out these studies in the near future. Though the micro-gyroscope that we studied sounds like a simple system its behaviour and interaction with the laser beam is very complex. In order to use this experiment to prove or disprove quantum friction it is first necessary to completely understand and model its complex behaviour. We need therefore more extensive experimental studies and more precise simulations.

((WN)) How challenging is research of this sort? What kind of difficulties are encountered?

MM: One of the challenges in this experiment is that it brings together many different parts of physics such as vacuum science, optical micro-manipulation, thermodynamics and potentially quantum mechanics. The main difficulty experimentally and theoretically is to combine all these fields simultaneously and make them work together to create a “clean” system that can test ‘friction’ or other theories.

((WN)) Previous research on the boundary between conventional and quantum physics has used atoms and individual molecules. Why was a sphere in excess of a million atoms appropriate for this experiment? Would that not move further away, rather than closer to, the boundary between the two?

MM: Quantum physics should not just be the remit of the world of atoms or molecules but should apply at all scales in some way. One of the main drives in present quantum technology is to create what is called mesoscopic or macroscopic quantum states, that is quantum states that can be see in a microscope. It is in the hope to achieve this that we chose to work with the micrometer sized vaterite crystals. The other reason for the size of the sphere is that we experimentally found that smaller spheres are presently more difficult to levitate.

((WN)) How likely is this result to be an anomaly? Might a similar ball break up more quickly, or be unable to spin as fast?

MM: With respect to the sphere break-up, these are interesting questions. One can expect that, depending on the mechanical failure property of the sphere, it would breakup sooner or later. Optically, we can make the sphere rotate at any speeds smaller than the maximum speed. So it would be very interesting to fabricate a series of spheres that have same optical properties but different mechanical failure points.

((WN)) Where would you like to see the research go next? More spheres?

MM: Indeed, two or more spheres would bring an additional degree of freedom to the experiments that would allow the study of the rotation rate as a function of the distance between them. Some theoretical predictions suggest that quantum friction effects might be enhanced in this case.

((WN)) If confirmed, what applications might quantum friction have?

MM: It is relatively easy to dream up applications for an effect that has not been observed yet! In general, friction dissipates energy and is seen as a detrimental effect. However, there are applications that use friction in a useful way. Indeed, velocity dependent friction could also be used to slow down microscopic objects to the point where these objects would reach what is called the quantum ground state for their centre of mass. Creating these states on demand would bring quantum technology a step closer and might lead us to “couple” quantum mechanically [macroscopic] objects — a phenomenon more accurately termed entanglement.

((WN)) One follow-up question for publication: You said you found smaller spheres more difficult to levitate. Why is that?

MM: I have double checked the sphere size problem. While it might be more difficult to use smaller sphere in the experiment due to the trapping geometry, as it turns out this was a sphere synthesis problem. With our present method we were not able [to synthesise] smaller spheres.

South Australia enters week-long lockdown to contain COVID-19 Delta variant spread

Friday, July 23, 2021

With five active cases of the Delta variant of COVID-19, South Australia begun a one-week lockdown on Monday. Announcing the lockdown, state Premier Steven Marshall declared “we have no alternative but to impose some fairly heavy and immediate restrictions”.

The first case out of South Australia’s active cases was presented to Modbury Hospital on Sunday night, having returned from Argentina earlier this month. The fifth, which Premier Marshall noted as “far more worrying”, visited The Greek on Halifax restaurant at the same time as someone who was later confirmed to be carrying the virus. Chief Public Health Officer for the state Nicola Spurrier said “if anyone has been at The Greek on Halifax they need to get into quarantine and get tested”.

In accordance with new regulations, there are only five reasons for South Australians to leave home: essential work, shopping for essential goods such as food, exercise, but only with people from the same household and within 2.5 kilometers (2 mi) of home, medical reasons (which includes testing and vaccination against the coronavirus, but excludes elective and cosmetic surgery), and caregiving.

Schools have closed for all but children of essential workers, with online learning having begun on Thursday. Face masks are also be mandated for those who leave home. ABC News reported that “support for businesses is expected to be announced…”, with all non-essential retail required to close under the new regulations.

How Does X Ray Digital Machine Function?

X Ray Digital Machine is an advanced form of x-ray inspection which produces a digital radiographic image instantly on a computer. This technique uses x-ray sensitive plates to capture data during object examination, which is immediately transferred to a computer without the use of an intermediate cassette. They’re the most popular form of diagnostic imaging, and they’re useful for a wide range of diagnostic and therapeutic procedures. The cost of operating the facilities used to process the photographs, as well as the hassle of maintaining and archiving the actual images, have long been associated with the usage of X-ray technology in medicine. Both of these problems was addressed by X Ray Digital Machine, adopted in the mid-1980s.X-ray Apparatus That Isn’t MoveableThis kind of transformer necessitates transformers of such size and output that they must be installed into the room and connected to the mains with special electrical connections.X-ray Apparatus That Can Be Used AnywhereThe portable X-ray has proven to be an invaluable method for diagnosing and treating patients in intensive care facilities, hospitals, and nursing homes where access to a radiology department is restricted. This equipment is ideal for low-volume or startup operations that have limited capacity. There is no need for lead insulation in the walls, and the transformers are tiny and light. Portable X-ray devices may be set up with minimal or no upfront investment.Apparatus for mobile X-raysThe emergence of handheld optical radiography X-ray devices is one of the most recent advances of Digital Radiography. These devices allow users to transport their medical supplies within the hospital. This is a remedy for imaging non-ambulatory patients who are unable to make the journey to the X-ray room or who are difficult to transport. Although the benefits of portable X-ray equipment, the picture accuracy of a chest radiograph taken at the bedside may be minimal. Mobile X-ray scanners have the benefit of being able to carry the equipment to the patient, as well as having better performances than handheld devices. It’s even on wheels and has bigger transformers.No filmNew optical X-ray devices often have the benefit of being flexible. While there are modern digital X-ray technologies that were built from the ground up, there are also digital X-ray technologies that enable the usage of old film-based technology by using a digital film cassette.Benefits for the PatientThe patient profits from digital X-ray scans as well. First, original diagnostic findings, as well as any subsequent X-ray images that might be needed, are collected in minutes or hours rather than days, thanks to the instant availability of the images. Second, unlike conventional film-based radiographic systems, most optical X-ray systems can be fine-tuned to a far greater degree.ConclusionOne of the most significant scientific breakthroughs in medical imaging in recent years has been using X Ray Digital Machine. In the same way as personal video cameras have been rapidly replaced by both dedicated digital counterparts and radiographic films in X-ray imaging could become redundant in a few years.
