    The song Sitting on the Dock of the Bay by Redding was right. When (Sittin’ on) the Dock of the Bay was released less than two months later, it became the singer’s first million-seller and first Billboard Number One single. But the legendary soul singer never got to hear the finished version of his breakthrough single: He had died in a plane crash on December 10th, 1967, almost a month before the song was released, (January 8, 1968).

    (Sittin' On) The Dock of The Bay


    So I’m just gonna sit on the dock of the bay

    Watching the tide roll away

    I’m sittin’ on the dock of the bay

    Wastin’ time

    Look like nothing’s gonna change

    Everything still remains the same

    I can’t do what ten people tell me to do

    So I guess I’ll remain the same, yes

    The word ‘viral’ has lost its meaning



          The nature of virality has shifted radically over the past decade as the internet has fractured into uncounted disparate algorithms, platforms, and niche communities. The volume of content being churned out every day has skyrocketed, the life cycle of each piece of media has grown shorter and social media platforms continue to inflate public metrics, devaluing previously impressive online stats.


            All of these factors have rendered the term “viral” nearly meaningless, say experts, and have led to a condition we’ll call “viralflation.” The term speaks to the diminished meaning of virality. If everything is labeled viral, then is nothing viral?


           “Back in the day, 1 million views was the thing,” said Marcus Stringer, a partner manager at Social Blade, a social media analytics platform. “That meant you’d gone viral, and you’d get picked up by news agencies around the world. Now, tens of millions of views is the norm for top YouTube channels. Soon, 20 million views will eventually become the norm.”


          “Because the concept of virality has been so watered down, truly viral pieces of content must reach hundreds of millions of people at a scale that’s increasingly unattainable for anyone but MrBeast,” said Lara Cohen, vice president of partners and business development at Linktree, a platform that allows creators to aggregate links to their social media profiles on one page. MrBeast is the internet name of Jimmy Donaldson, YouTube’s most watched creator.


            A decade and a half ago, there was a clear delineation between viral content and the vast majority of media that users would encounter every day. The internet was smaller, and most sharing was manual (people emailing and messaging links to each other) or via early internet aggregators such as sites like Digg and StumbleUpon.


             Viral content emerged slowly, so the life span of a viral video was long. Some content remained viral for up to a year, worming its way through the internet as it gained traction. When social media platforms began to switch to algorithmic feeds optimized for engagement in the mid 2010s, the viral content cycle accelerated, experts said. Brands began recognizing the power of virality and started to attempt to manufacture it. Content creators joined engagement groups where they’d reshare each other’s content in attempts to force virality.


           Platforms themselves also began to realize the power of virality and sought to generate it, or at least generate the appearance of it. This was the beginning of the era of viralflation. Facebook helped lower the industry-wide threshold for what counted as a video view, and began inflating view counts on various Facebook videos in an effort to make them appear more viral than they were.


          Then TikTok broke into the mainstream in 2020, lowering the bar even further for what counted as a “view.” While a view on Facebook counts after three seconds of watch time, a view on TikTok is simply an impression, meaning the video was served to a user for at least a fraction of a second on screen. According to the company, TikTok also counts each loop of the video as a view, allowing videos to rake in massive view counts.


           “The speed at which we cycle through trends and sort of moments of virality on the internet is faster now largely because of TikTok,” Cohen said. This has created an arms race among tech platforms to see which could inflate metrics the most. There’s been an incentive to have these numbers look bigger because they look better to advertisers, so there’s a financial incentive to cause this viral inflation.


           A new class of content creators also has raised the bar for what’s considered viral. “When MrBeast started to explode, things really started to change in the landscape,” Stringer said. “People didn’t consider [earlier metrics of virality] viral anymore, because he’s getting multi millions of views per video.”


         Coco Mocoe, a trend forecaster in Los Angeles, said that along with these shifts, users are also consuming a higher total amount of content online per day, especially members of Generation Z, those born between 1998 and 2012. They are more likely to consume all forms of media through the internet and social platforms, rather than via newspapers or TV. And, much of that content is short form and less than 60 seconds long. “The main reason there are bigger numbers now is because people are consuming so much more content in a given sitting,” she added.


         This has made virality more ephemeral. “There’s not that same… permanence,” Mocoe said. “If you’re watching 50 videos with 1 million views, you’re less likely to remember one as opposed to a decade ago, when you might only watch five videos a day, and just one would have 1 million views.” For the average consumer, viralflation has made it increasingly difficult to tell what is and isn’t actually viral. Because we no longer have any shared sense of virality, it makes it easier for people who don’t understand the mechanics of the internet to fall for fake viral trends.

Não há nenhum princípio universal que determine o que estes direitos e obrigações serão, mas as sociedades nas quais a cidadania é uma instituição em desenvolvimento criam uma imagem de uma cidadania ideal em relação à qual o sucesso pode ser medido e em relação à qual a aspiração pode ser dirigida”.

    É possível constatar, na vida moderna, a diminuição da interação física entre pessoas nas sociedades que possuem maior acesso à comunicação digital. As pessoas isolam-se em suas residências com o crescente e fácil acesso à Internet e, talvez, aliado ao temor da violência, este isolamento se justifique ou seja melhor explicado; contudo, é preciso comprovar tal afirmação por meio de pesquisas consolidadas. É certo, entretanto, que há benefícios deste mundo digital, como a maior interação entre pessoas de diferentes partes do mundo e de culturas diversas. Esta comunicação significa maior possibilidade de trocas de ideias e de conhecimentos como nunca antes experienciadas na história humana. Porém, existem perspectivas sociológicas que apontam riscos neste novo mundo virtualmente conectado como, por exemplo, a insegurança das interações digitais que possibilitam que se edifiquem e se desmanchem relações humanas com igual e rápida facilidade. E isto é certamente prejudicial para a construção de um mundo social que necessita de relações duradouras para se manter e não de relações que se liquefazem em um simples mexer de dedos em uma tela.

Ele explicou que, em uma transformação cíclica, um sistema retorna ao seu estado inicial definido em termos das variáveis de estado, pressão, volume e temperatura, após passar por uma série de processos termodinâmicos. Na sequência, o professor propôs um problema teórico envolvendo um motor térmico ideal, operando em ciclos, no qual o sistema realiza trabalho sobre o ambiente e troca calor com dois reservatórios térmicos, sendo um quente e o outro frio, com temperaturas T1 e T2 respectivamente.
