In the US, Biden promises to destroy « highways of racism »

Across the United States, the highway system dating from the 1960s was built without thinking about the social consequences. In many states, highways that cut through cities cut society in two.

The US Senate on Tuesday passed the historic $ 1 trillion infrastructure plan promised by President Biden. The « historic project » must now be voted on in the House of Representatives. He promises to renovate roads, bridges, electricity networks, expand internet access, all while respecting the environment and taking into account the fight against global warming. Nestled in this law, the destruction of « roads of racism ».

These  » roads of racism  » cut cities in two and draw a red line which delimits a kind of segregation. On the one hand, the « frequentable » suburbsmiddle classes, even upscale. On the other, minority communities, often poor and often black populations. These highways are part of the historic highway system of the United States. They were built between the 1950s and the 1970s. Town planners of the time sought to build where property values ​​were lowest, and therefore cheapest to buy. Thousands of traders, businesses and residents left these areas and never returned. At the same time, it has allowed the middle class to settle in suburban areas and to make daily trips to the city center.

Degraded living conditions

These urban highways have dramatic consequences for the populations who live nearby, especially pollution. In the Bronx, a former resident of the Cross Bronx Expressway recounts: « As a son of the Bronx, I grew up in three places at the same time – home, school and hospital, because I had seizures. recurrent asthma «  . According to US Congressman Richie Torres, originally from that New York City neighborhood, the asthma hospitalization rate in the South Bronx is two to three times higher than in the rest of the city. 

In New Orleans, near the Claiborne Expressway , built in 1968, residents hear the sound of cars night and day, passers-by are suffocated by exhaust fumes. Around this urban highway, nearly 40% of the inhabitants live below the poverty line, against 25% for the rest of the city.

For the White House, which cited the example of New Orleans , these highways have caused the ruin and grief of underprivileged communities, destroyed businesses, polluted the air, « racism is physically embedded in some highways », Transport Secretary Pete Buttigieg said.

Remove all highways?

The solution proposed by the president is rather radical and the idea is not to destroy all the urban highways. What is likely to happen is that every state and every city will rethink space. In environmental terms, in terms of transport and in social terms, and this is all new. In Syracuse, New York, for example, part of the highway will be destroyed and a boulevard built instead. Traffic would be diverted elsewhere. This project alone is two billion dollars, supported by the State of New York and helped with federal funds. On the other hand, in New Orleans, officials have already announced that destroying Claiborne Expressway was not a priority, because it was too expensive . 

This destruction is not necessarily well received by the inhabitants of the areas concerned. « It’s a virtuous signal, » a Syracuse resident told the BBC ,  » but it won’t help matters. » In the meantime, her 61-year-old neighbor washes her furniture as she does every day, covered by the dust from the highway.

Olympic Games: Why do athletes run counterclockwise?

Running counterclockwisewas not always the case

The Tokyo Olympics are over. But do you know why in a stadium, athletes run counterclockwise? Solenne Le Hen explains to us that this is not due to chance.

Running counterclockwise, we also say running «  counterclockwise «  , this was not always the case. In the very first Olympics, from 1896 to 1912,  athletes just ran the other way, clockwise. And they complained because in the corners they felt bad sensations. As a result, the organizers have changed and since then this sense of racing has even been included in the regulations of the International Athletics Federation.

In fact, for everyone, including professional athletes, if we have to do a loop, we will naturally run counterclockwise. Moreover, the newspaper Le Progrès noted it in Lyon. At the Parc de la Tête d’Or, says the daily, « on this running highway of nearly 4 km, the pack turns like in a roundabout in the direction of the needles of a clock.  » A matter of instinct. therefore and the journalists even counted the runners. Only one in 30 runs the other way. 

The brain at the origin of this displacement by turning naturally to the left

A Japanese scientist, Hideaki Fukami , understood that athletes feel more comfortable with the rope on their left for neurological reasons, because of the right hemisphere of the brain, the one that controls the perception of space and at the same time that controls the opposite part, the left half of our body. Thus the perception of our body would be better by turning to the left.

Moreover, explains this researcher, 80% of the criminals of the prefecture of Hyogo, in Japan, when they flee, flee towards the left. This is justified on a sporting level. Experiments were carried out with top athletes, asking them to run 400 meters turning to the left, and 400 meters turning to the right. Counterclockwise, they run faster: two seconds less on average.

HOW MUCH IS AN OLYMPIC MEDAL REALLY WORTH AT THE CURRENT METAL PRICE?

Small disappointment for the big winners of the events in Tokyo: their gold medal has very little of the yellow metal. But the current prices of gold and silver still give it a nice value.Publicity

So inevitably, they don’t train for years for that. But the Olympic medalists also leave with a beautiful object around their neck, made with noble materials.

With 339 finals in Tokyo this year, it is impossible to distribute medals worthy of their denomination: disappointment, the gold medals are therefore not gold.

However, we do find a little of the yellow metal: 6 grams to be precise, as provided for in the Olympic regulations, out of the 556 grams in total for the most beautiful of the medals, or 1.2% of the total mass. The rest is money. 6 grams of gold is not much, but at the current price of gold, it still represents around 300 euros.

The bronze? Rather copper

A safe haven par excellence, gold has seen its price increase for several years, with a strong acceleration during the onset of the financial crisis. The one kilogram ingot flirts today with 50,000 euros against less than 35,000 euros at the last Olympic Games in Rio in 2016.

Less impressive, the price of silver also climbed in favor of the crisis to reach 665 euros per kilogram. A gold medal « is therefore » worth approximately 660 euros (gold plus silver) against 360 euros for a silver medal (only in silver) and… 3.5 euros for a bronze medal, composed mainly of copper.

how was the earth formed?

The Earth formed when gravity attracted swirling gases and dust to become the third planet from the Sun,

A mixture of swirling gas and dust

About 4.5 billion years ago, the Solar System gradually adopted this arrangement that we know today. At this time, an interstellar molecular cloud collapsed, composing the Sun at its center. Around, a disk of gas and dust appeared.  » The Earth formed when gravity attracted swirling gases and dust to become the third planet from the Sun,  » observes  NASA on its website. Each planet in the Solar System has formed with a mixture of its own. But where does this dust come from which finally condensed to give our planet?

According to a study published at the end of 2019 in the journal Nature Astronomy and relayed on the Sciences et Avenir website, it would come in part from red giants, old stars which have already burned their hydrogen, as will be the case for our star within 4 to 5 billion years. To achieve this result, the researchers performed measurements of the abundance of palladium. This element, which is formed during the process of « slow neutron capture » taking place in the hearts of red giants, was remarkably present in our planet. The latter therefore inherited, in « its mixture », dust from one of these old stars. In general, stars disperse throughout their life or at the end, thanks to stellar winds, by exploding, or even by merging, chemical elements which are the building blocks of matter.

And the Moon in all of this?

According to the theory most accepted by the scientific community, that of the « giant impact », the Moon was created around 4.5 billion years ago when the primitive Earth was violently struck by a celestial body named Théia (mother of the Moon, Selene, in Greek mythology). The proto-planet was as massive as the planet Mars and the shock was tremendously violent. It vaporized Théia and a large part of the earth’s crust and mantle, poor in metals. Part of the cloud of vaporized rocks would have aggregated to Earth again, while the other part would have solidified not far away, giving rise to our satellite. 

Problem: the lunar subsoil is richer in metals than the portions of Earth excavated by Théia. This fact has long been known to scientists who are looking for an explanation. But a new study relayed by Sciences et Avenir in 2020indicates that there are still more metals than imagined which makes it even more difficult to interpret this shift while preserving the hypothesis of the giant impact. The study’s authors suggest that the collision between Theia and Terra was more violent and devastating than expected, and propelled deeper sections of the planet into orbit, including chunks of cores much richer in metals. Unless the collision happened much earlier when the Earth was still a ball covered in molten magma. Other theories exist to explain the formation of the Moon, some call for  a series of impacts  and others even believe that our satellite is  older than the Earth. ! Further investigations will still be necessary to settle this thorny debate.

Donald Trump demolishes The American Team After The olympic games

Yellow hair against purple hair

Following the bronze medal won by the Americans on Thursday , Donald Trump, former President of the United States, saw fit to give his opinion on the medalist group: « If our football team, led by a radical group of crazy left, was not « woke », they would have won the gold instead of the bronze. « 

But Trump didn’t stop there, he went on to attack Megan Rapinoe, who aside from her major role in the Yanks collective , is also a figure in the struggle for LGBT + rights and a staunch opponent of Trump. « The woman with purple hair played very badly and spends too much time thinking about the radical left politics and not doing his job, » said the 45 th US president.

Rihanna officially billionaire, according to the classification of « Forbes »

The 33-year-old Barbadian is officially a billionaire according to the Forbes ranking

The famous singer and businesswoman Rihanna joins the prestigious Forbes ranking and becomes the richest musician in the world with an estimated fortune of $ 1.7 billion.Article written by

« I only see dollar signs , «  Rihanna sang on her hit Pour It Up . A title that fits perfectly with the new financial course that the designer has just passed.

The 33-year-old Barbadian is officially a billionaire according to the Forbes ranking. With an estimated wealth of 1.7 billion according to Forbes , Rihanna is placed just behind Oprah Winfrey and thus becomes the richest singer in the world. And yet, it is not thanks to her art that she has become so rich.

The Fenty Beauty Empire

In 2017, Rihanna created Fenty Beauty, a cosmetics brand in partnership with LVMH. The make-up line therefore relies on inclusiveness by offering a foundation available in 50 shades, making it easier for women and men of color to find a product suited to their skin tone.

The products very quickly know a worldwide craze and eventually overtake other lines of cosmetics created by other celebrities, such as Kylie Cosmetics by Kylie Jenner. According to Forbes , the company is now valued at $ 2.8 billion (€ 2.35 billion) of which 50% is owned by Rihanna.

La Barbadienne does not stop there and in 2018 launches Savage x Fenty, a line of lingerie that operates on the same principle of inclusiveness by offering underwear for each body type. A company also supported by LVMH and that Forbes estimates at $ 270 million. The singer owns 30% of the shares, the rest belonging to the French luxury group. 

Failure of ready-to-wear

But all is not perfect in this success story . His ready-to-wear brand Fenty, deemed too expensive and impacted by the health crisis, ended up disappearing.

With a fortune estimated at 1.7 billion dollars, Rihanna overtakes another artist turned businessman: Kanye West. With a wealth valued at $ 1.3 billion, the rapper and his shoe and clothing brand Yeezy are behind the singer of the famous Umbrella .

Cock-a-doodle Doo ! Jeff Bezos is no longer the richest man in the world, he was overtaken by Bernard Arnault. The latter is the majority shareholder and CEO of the LVMH group, which owns brands such as Louis Vuitton, Christian Dior, Tag Heuer , Sephora and Tiffany. LVMH shares have climbed more than 35% in 2021 and even 140% from a low in March 2020 at the start of the pandemic. Last Monday, the fortune of Bernard Arnault was estimated at 186.3 billion dollars, or 300 million more than that of the founder of Amazon.

MarketWatch explains that this rise is undoubtedly linked to the Covid-19 crisis, which had affected the luxury sector in 2020. Since the health situation has improved and the borders reopen, luxury is in great shape. No need to worry about LVMH anymore: the group announced 7.6 billion profit in the first half of 2021, four times more than for the same period in 2020 or 44% more than in the first half of 2019.

What will be the best places to live if society collapses?

A study by the scientific journal Sustainability lists the best places to settle in the event of economic or climate collapse. A list that gives pride of place to several islands such as Iceland or Tasmania.

According to the authors of this study published on July 21, 2021 in the scientific journal Sustainability , a collapse of our societies could be illustrated in different ways in the years to come:

“Since its inception, human civilization has experienced a continuous trajectory of increasing socio-political complexity, a trend which has accelerated dramatically recently. This phenomenon has resulted in increasingly serious disturbances of the Earth system, which have recently manifested themselves in planetary effects such as climate change . These effects create an increased risk of a global collapse event, « said the researchers behind the survey.

These alarmist predictions sadly recall the report of the IPCC – Intergovernmental Panel on Climate Change – which revealed last week that two regions of the globe have now become almost uninhabitable for humans . Worrisome data, published a few days before Overshoot Day , which occurred this year on Thursday July 29, the date from which we have exhausted all of the resources that the planet is capable of generating in a year.

Countries better prepared for environmental change

To carry out this study, the journal Sustainability drew on research results from the American University of Notre Dame-Global Adaptation Index , which in 2015 assessed and ranked countries in terms of vulnerability and preparedness to climate change to to come.

Several criteria were taken into account such as:

  • the ability to produce food for the population;
  • the ability to maintain an electricity grid;
  • overall production capacity.

Islands with a temperate climate and sparsely populated

The best-suited places in the world to survive a possible societal collapse according to the Sustainability report are:

Results that can be explained in particular by fertile agricultural land, low energy consumption, temperate climates and low population density.

« These places which have not suffered the most glaring effects of previous societal collapses are described as ‘lifesavers’ for human populations in the event of collapse, in particular thanks to the persistence of agriculture » , concludes l ‘study.
