Meditações - não há espaço nem tempo
In the elementary grammar of the world, there is neither space nor time—only processes that transform physical quantities from one to another, from which it is possible to calculate possibilities and relations.

Meditações - o universo como uma sucessão de eventos
There are actually no things at all. Instead, the universe is made up of countless events. Even what might seem like a thing—a stone, say—is really an event taking place at a rate we can’t register. The stone is in a continual state of transformation, and on a long enough timeline, even it is fleeting, destined to take on some other form.

Meditações - a nível quântico, não há tempo
From our perspective, the perspective of creatures who make up a small part of the world—we see that world flowing in time. At the quantum level, however, durations are so short that they can’t be divided and there is no such thing as time.

Meditações - o tempo como perspectiva
Time is merely a perspective, rather than a universal truth. It’s a point of view that humans share as a result of our biology and evolution, our place on Earth, and the planet’s place in the universe.

Meditações - cronologia e continuidade
Chronology and continuity are just a story we tell ourselves in order to make sense of our existence.

Há 110 anos - notícia sobre a primeira travessia aérea do Canal da Mancha, com um relógio Zenith a bordo
Há exactamente 110 anos, o Daily Graphic de 26 de Julho de 1909 trazia na capa o aviador francês Louis Blériot e o seu monoplano, depois de ter conseguido a primeira travessia do Canal da Mancha por "uma máquina mais pesada que o ar". O voo durou 23 minutos e Bleriot usou um relógio Zenith durante a travessia (imagem em baixo). Saiba mais aqui.
Relógios IWC saudam os 125 anos da Mercedes no desporto automóvel
A Mercedes-Benz celebra este fim-de-semana o seu 125º aniversário no mundo motorizado, estando presente no Grande Prémio da Alemanha em Fórmula 1. A manufactura suíça de relojoaria IWC tem com a construtora automóvel alemã a sua mais velha parceria (desde 2004). E não deixou passar en claro a ocasião.
Do couminciado da IWC:
Back in July 1894, the world‘s first competitive car race took place from Paris to Rouen. With two of the winning vehicles powered by engines developed by Gottlieb Daimler and Wilhelm Maybach, it was the first foray into racing by the German manufacturer. Known since 1926 as MercedesBenz, the company continue to secure countless triumphs in motorsport events around the world, most recently powering Formula One™ driver Lewis Hamilton to victory at the British Grand Prix.
Commenting on the landmark anniversary, Christoph GraingerHerr, CEO of IWC Schaffhausen said: “On behalf of everyone at IWC, I want to send my best wishes and sincere congratulations. The racing history of Mercedes-Benz is full of amazing cars, engines and victories, and to have performed with such a level of passion and dedication over the last 125 years is truly remarkable. IWC recently shot a campaign with Lewis, the Mercedes-Benz Silver Arrow W125 and an original spitfire aircraft. Bringing together a five-time Formula One™ World Champion, with two legendary icons of motorsport and aviation, was a complete privilege and a fitting celebration of our long and fruitful collaboration with Mercedes-Benz.”
Indeed in 1894, at the same time as Daimler and Maybach’s cars were charging to Rouen, IWC was in a race of its own, testing the Calibre 65 movement at the Observatory in Neuchâtel. Just like Mercedes-Benz’s predecessor brand, Benz & Cie, IWC emerged victorious, achieving the best result of all pocket chronometer watches in the competition. Fast forward to 1936, and Albert Pellaton, who would eventually become IWC’s technical director, visited the Swiss Grand Prix. The master watchmaker had developed the timing system for the Bern event, and took time out of his duties to visit the pits. A stunning photograph of the moment Pellaton passes by the Mercedes-Benz garage is thought to capture the very first encounter between the two brands.
Thereafter, both Mercedes-Benz, in motorsport, and IWC, in watchmaking, continued to push boundaries in their determined pursuit of excellence. In 2004, the companies decided to join forces, with IWC becoming a partner of Mercedes-AMG, the high-performance brand of MercedesBenz. It was the start of a long and fruitful collaboration, which continues to this day. As well as an on-going relationship with AMG Motorsport, in 2013 IWC became the “Official Engineering Partner” of Mercedes-AMG Petronas Motorsport. The Swiss watchmaker also collaborates with Mercedes-Benz at the Goodwood Members’ Meeting, competing in classic car races with its own dedicated team and car, the iconic Mercedes-Benz 300 SL.
To celebrate Mercedes-Benz’s 125 years of motorsport, the W10 cars of Lewis Hamilton and team mate Valtteri Bottas will sport commemorative liveries at this weekend’s Formula One™ event at Hockenheim. As part of the new look, the current IWC logo will be changed to a special vintage version of the emblem, which fittingly was first used by the company in catalogues in 1894.
“We are immensely proud of our lengthy and enduring partnership with Mercedes-Benz,” concluded Grainger-Herr. “We wanted to commemorate this important anniversary, and to add one of our classic logos to the livery, from the year the company started its motorsport story, seemed like a special way to celebrate. Long may our combined quests for ultimate perfection continue!”
Meditações - o fascínio pelo tempo
Time is a fascinating topic because it touches our deepest emotions. Time opens up life and takes everything away. Wondering about time is wondering about the very sense of our life. This is [why] I have spent my life studying time.

Meditações - o tempo não existe
Time feels real to people. But it doesn’t even exist, according to quantum physics. “There is no time variable in the fundamental equations that describe the world,” theoretical physicist Carlo Rovelli tells Quartz.
