A Magical Moment

Dear:
        Your Sunday newspaper...yesterday the US put two astronauts in orbit in a US spacecraft for the first time in 9 years. One of the astronauts, Colonel Doug Hurley, graduated from my university Tulane in 1988 with a degree in civil engineering. With a pandemic and rioting going on, this flight took people's minds off hard times. It gave us all a chance to look up to the sky.
         My mind goes back to December of 1968. The US was in the Vietnam War. On average, 500 young US men and women were dying each week in Vietnam. Our cities were wracked with riots. There were violent political protests and political instability. President Johnson wanted to give a Christmas gift to the US. He wanted to take everyone's minds off the bad times. He authorized NASA to use a Saturn 5 rocket to send three US astronauts on a trip around the moon.
      The Saturn 5, to this day, is the largest operational rocket ever built. It has 5,600,000 parts and systems that have to work together perfectly. When Johnson made the decision, it had only been used to put astronauts in orbit around the earth. It was an incredible risk. Astronauts Frank Borman, Jim Lovell, and Williams Anders all had a frank talk with their wives. They told them to prepare to be widows. There was a 60% chance that the mission would fail and they would die in space.
    As they say, the rest is history. The Saturn 5 worked flawlessly. The Apollo spacecraft orbited the moon, Frank Borman read from Genesis at Christmas time as the whole world listened. Some stunning pictures of our world were taken. All watching forgot about their problems and pain in life.
        We need more uplifting moments like these!

The Fastest Internet In The World

The Dream of Speed

The average internet user occasionally complains about the slow speed of their network but that whine has become more frequent as lockdowns forced people to stay at home during the coronavirus pandemic – and use up bandwidth.
Australian scientists, however, recently recorded the world’s fastest internet data speed and might be getting closer to a solution for the bandwidth problem, the BBC reported.
In a new study, researchers registered a data speed of 44.2 terabits per second, equivalent to the download of more than 1,000 high-definition movies in less than a second.
In comparison, the average download speed in the United States is 135 megabits per second – a tiny fraction of that.
Lead author Bill Corcoran and his team achieved the record speed using a “micro-comb” that replaced around 80 lasers found in some existing telecoms hardware. The equipment was tested outside laboratory settings on existing infrastructure.
The results displayed the highest amount of data ever produced by a single optical chip, currently used in modern fiber-optic broadband systems around the globe.
Corcoran hopes that the study could offer better insight and potentially transform internet connections in the future.
“This data can be used for self-driving cars and future transportation, and it can help the medicine, education, finance, and e-commerce industries – as well as enable us to read with our grandchildren from kilometers away,” he said.

Anti-China Sentiment Is Rising!!!

CHINA

The Virus and Goliath

Anti-China sentiment is reaching levels not seen since the crackdown on pro-democracy activists on Tiananmen Square in 1989, according to an internal Chinese report reviewed by Reuters. Chinese leaders are even afraid that the current climate is leading to a military confrontation with the US.
The cause of the plunge in support is obvious. Folks around the globe blame Chinese leaders for the coronavirus pandemic. It’s a development that could reorient international relations worldwide for a generation.
Countries that were formerly open to expanding their diplomatic and economic relationship with China are having second thoughts, while China is retaliating against those setbacks, the New York Times wrote.
Relations with the US are especially bad. President Donald Trump, who already believed China unfairly undermined American business, blames China for the lockdowns that have resulted in millions of unemployed Americans. Many are openly discussing the potential for a new Cold War, the South China Morning Post reported.
Some say it has already started.
On Wednesday, for example, the US House of Representatives almost unanimously passed legislation calling for sanctions against Chinese officials for the detention and torture of Uighur Muslims in the country’s western region of Xinjiang, CNBC reported.
The timing is interesting – China’s treatment of the Uighurs is not a new development.
Meanwhile, the vote came just hours after US Secretary of State Mike Pompeo targeted Beijing over its efforts to clamp down on dissent in Hong Kong, announcing that the State Department no longer viewed the island as autonomous. This means that Hong Kong no longer merits being treated differently from the mainland under US law, and could change Hong Kong’s preferential trade hub status. He also expressed support for protesters there.
That follows moves this month to place sanctions on Chinese banks and a measure to force Chinese companies on the American stock exchanges to become more transparent, or de-list.
Meanwhile, others are jockeying to deal with the new environment.
Defenders of Taiwan, like Washington Post columnist Josh Rogin, argued that the pandemic shows why the US should embrace the democratic island that leaders in Beijing view as a breakaway Chinese province.
British officials are moving to shorten their contract with Chinese tech giant Huawei to build a 5G telecommunications network in their country, the Financial Times reported Saturday. The idea seemed wise when Britain was looking for new trading opportunities amid the debate about how to leave the European Union. Now China is not such an attractive partner.
Countries around the world are rethinking their supply chains to move away from China. And there are many waiting in the wings ready to jump at the opportunity.
Indian Transport Minister Nitin Gadkari recently told the BBC that said China’s fall from grace could be a “blessing in disguise” for his country’s efforts to attract manufacturing away from the world’s most populous country.
Earlier this month, India moved to offer land to lure foreign businesses already eying an exit from China, Bloomberg reported. Land has been one of the main hurdles for foreign investment in India, with companies required to acquire land on their own and negotiate directly with the owners of small holdings.
Chinese leaders are not taking such moves lying down, though, Voice of America said.
They pressured the EU to soften a report that was critical of the country, for example, while belittling and mocking European leaders for their handling of the pandemic – the latter was to appeal to a Chinese audience.
After Australia called for an inquiry into the origin and transmission of the virus, China slapped tariffs on Australian barley, according to the Associated Press. That came after China banned imports of Australian beef ostensibly over labeling issues.
And after African officials also called for an inquiry into the pandemic and African ambassadors to China demanded explanations as to why Africans expatriates in the country faced mistreatment, President Xi Jinping detailed a massive aid package for developing countries. The move was designed to cement China’s ties to African countries that provide crucial resources for the Chinese economy, CNN explained.
Even so, Chinese bullying and money might not be enough, say analysts, who note that anti-Chinese sentiment was rising in Europe, Asia and Africa even before the pandemic hit.
If China loses its diplomatic and economic might in the near future, say analysts, it will be shocking: Because no one ever thought a virus could bring down such a mighty giant.

Rebels With Paws

Rebels with Paws

Teen angst doesn’t just affect humans but man’s best friend as well, according to new research.
Scientists in the United Kingdom found that dogs go through the same “rebellious” phase as humans during adolescence, Science Alert reported.
In their study, the research team analyzed the behavior of more than 370 pooches to observe whether their behavior changed as they aged.
They noted that once canines reached eight months – the start of puberty in dogs – their behavior shifted: They were less inclined to heed their owners.
In one experiment, the team observed how 93 dogs consisting of “teen” Labrador retrievers, golden retrievers and mixed-breeds hesitated to follow a “sit” command when their owners ordered it.
The researchers added that this behavior was not present when the dogs were younger than eight months, or when they overcame their angsty phase.
Moreover, this defiant attitude was mostly directed at the owner and seen less often when strangers gave commands.
Lead researcher Lucy Asher explained that this is an important period in a dog’s life and that the pup needs patience and attention – like a human teenager.
“It’s very important that owners don’t punish their dogs for disobedience or start to pull away from them emotionally at this time,” said Asher.

Mako Energy-Turning Waves Into Electric Power

Surf’s Up

Australian waters are perfect for surfing and shark-spotting with around 180 shark species. Now, the Sydney-based Mako Energy is looking to exploit its oceanic tides as a renewable energy source, CNN reported.
Mako Energy has created underwater turbines that can power homes using slow-flowing water in rivers and oceans. The turbines are up to 13 feet in diameter and can generate enough electricity to power up to 20 homes.
The technology is still in its infancy, but what sets it apart from wind and solar energy is its predictability: The sea moves in predictable tidal currents, unlike the sun and wind.
The main drawback, however, is that the turbines are very expensive to install. Also, it is unclear what impact the tidal installations may have on marine life.
Currently, a Mako turbine ranges from $20,000 and $70,000, depending on the power output and the location. The company says it is working to make them more affordable.
“We’re developing turbines at a scale where they can be deployed easily in remote communities, coastal businesses, island communities and resorts,” said Mako’s Managing Director Douglas Hunt.
