Two atomic watches in space

April 15, 2025 by usatoday24

The European Space Agency is about to empirically verify one of the most fundamental theories of physics. To try this at home, you will only need an atomic clock and a space station. Three decades of gestation. After 30 years in development, the launch of the ACES INSTALLATION (Atomic Clock Ensemble in Space) is just around the corner. This ambitious ESA project will send a set of atomic watches of very high precision to the International Space Station to measure how gravity affects the passage of time. ACES not only hopes to validate, with unprecedented precision, the effect of the gravitational expansion of time, predicted 100 years ago by Albert Einstein in his theory of general relativity. He also hopes to open the door to new research on fundamental constants and dark matter, in addition to Improve time synchronization global. A little context. According to Einstein’s general relativity, gravity deforms space-time, which has a direct consequence: time goes at different speed depending on the intensity of the gravitational field. Experiments on Earth have already shown that Watches on the top of the mountains (where gravity is slightly lower) they go infinitesimally faster than the watches located at sea level. ACES will take this concept to the extreme. Orbiting 400 km on Earth aboard the ISS, the instrument of ESA will experience a remarkably weaker gravitational field than on the surface. The objective is to create an “atomic watches network” comparing the signals of ACES instruments with the most precise watches on Earth. It will be this comparison that allows measuring temporary dilation more accurately than ever. In addition to ratifying general relativity, ACES will accurately measure the differences in gravitational potential between continents, will verify If the universal constants of physics are constant Over time, and will discover whether dark matter interacts with atomic watches. Two watches better than one. The heart of ACES are two complementary atomic watches with each other. Pharao (Projet d’Onomique atomique French space agency CNES. AND SMH (Space Hydrogen Maser), produced in Switzerland by Safran Time Technologies. Pharao is an atomic cesium clock. Use lasers to cool cesium atoms to almost absolute zero (-273 ° C). This extreme cooling allows incredibly precise time and frequency measurements. Pharao is much more compact than its terrestrial equivalents (which can measure several meters high), since in microgravity, the atoms “float” more time in the interaction zone, without having to launch vertically against gravity. SMH uses hydrogen atoms as a frequency reference. It is an active masier, similar to those used in Galileo navigation satellites, but ten times more stable. It shines for its short -term stability, in periods of up to an hour. Combining this short -term stability with the long -term precision of the Pharao, ACES will offer a time signal with amazing precision, of only a second every 300 million years. Launch by Spacex. After being assembled and subjected to tests at the Airbus facilities, ACES traveled in March 2025 to the NASA Kennedy Space Center, in Florida, where ESA, Airbus and NASA engineers completed the final preparations in a clean room before its launch. The take -off of ACES to the ISS is scheduled for April 21 aboard the CRS-32 repayment missionin a Spacex dragon ship. Once at the orbital station, a robotic arm will install the instrument outside the European Columbus module. It will be operational for 30 months, collecting data continuously.

I have tried many sports watches and these are the ones I recommend for amateur athletes

March 27, 2025 by usatoday24

Sports watches, and also activity bracelets, have become Perfect companions of each of our training. Unlike the somewhat limited models we found a few years ago, today there are a wide variety of options to choose from, and many of them are very complete. In this article we have gathered different sports watches that we have tried and that we have loved. To do this, I have spoken with some companions of Xataka and Webedia And they have recommended some quite interesting models. Not only records data, but it interprets and guides you to improve Javier Lacort He told me that a recommendation was not going to happen to me, but a Bible. He did not want to just offer a single model, but three so that we can choose the one that best suits the needs of each person (and each budget). Suunto Race The first sports watch recommended by Javier Lacort is ideal for those who want A clock with which you do not need to learn concepts. Simple and plain to start exercising accompanied by, in this case, the Suunto Racethat we can find in Amazon by 449 eurosalthough the English Court has it for 399 euros. I was surprised with his Zonense technology That, although it requires a pectoral band, brutally simplifies training with only three colors. It shows you exactly how your body responds that day, adjusting to your fatigue or recovery. It is perfect whether you are looking to improve your brand in marathon as if you just want to walk to lose weight. Simple to more power For those who do not want to have to invest a long time learning concepts. * Some price may have changed from the last review Garmin Epix 2 The second model recommended by Javier Lacort enters fully into the Garmin catalog. After spending a lot of time with Apple Watch, he made the leap to Garmin Epix 2a sports watch that we can find in Amazon by 614.94 euros. Is it expensive? To do this, It also mentions other cheaper models. My day to day is with an epix 2, but there are cheaper options such as Forerunner 255 or the 265 that maintain the essential, even even more basic and cheap such as the Forerunner 55. What conquered me was its depth: Not only records data, but it interprets and guides you to improve. The battery that lasts a whole week and the brutal customization of training screens make a difference for any athlete who wants to understand his body. * Some price may have changed from the last review Apple Watch Se The third and last sports clock recommended by Javier Lacort is nothing less than an Apple Watch, in general Any model can serve us for our training. However, if we want something simple, we have the Apple Watch Se by 229 euros In Amazon. The Apple Watch is ideal if you are already in the Apple ecosystem and look for balance. It has very good GPS and an impeccable interfacealthough it falls short for more detailed training and its basic analysis. It shines as Mini-Iphone on the wrist (messages, music, payments), but you will need several payment apps to get what Garmin or Suunto offers as standard. And not even so. If you deliberately look for something basic and simple, then go ahead. He Model se It will serve you. Apple Watch SE (2nd Generation) * Some price may have changed from the last review The screen very large and perfectly visible even in full sun Raquel Rodríguez (Lady Fitness), director of Trendencies and former director of Vitónica, also wanted to comment on what their personal recommendations are with Two very interesting proposals. Garmin Venu 2s The first sports watch recommended by Raquel is none other than Garmin Venu 2sa sport -oriented model that offers a elegant design To carry on a day -to -day basis. We can find it in Carrefour by 270.99 euros. The clock I use now and with which I am very happy, since being a model Designed for small dollswith a round sphere and with a careful aesthetic, I can take it both in training and on a day -to -day basis (I even took it to a wedding and did not disregard anything with all the outfit). What I like most about this clock: The screen very large and perfectly visible even in full suna battery that lasts days and days (and I am one of those who train daily), and that has up to 25 different sport profiles (running, pilates, hiking, strength training, Hiit). It is very complete, very nice and ideal for an amateur athlete who seeks to register his training and learn from them. * Some price may have changed from the last review Fitbit Versa The second sports watch currently has a most restrained price that other models that we have previously commented. He Fitbit Versa 4 We can find it for 149 euros during the spring offers. This is a bonus that I leave as an idea For people who want to move more. My parents, both retirees and committed to taking the 10,000 daily steps, are the one in different versions. They came from a simple Garmin activity bracelet that fell a little short in terms of functions, and now they are very happy with their fitbit: they tell the steps, monitor sleep and can access others Functions from the same clock such as WhatsApp Or what time will you do. It is a very interesting way of inviting older adults to be challenged and active. * Some price may have changed from the last review It has a very comfortable design and comes with pre -established routines Most of the wearables that I have used have been bracelets, and not so much smartwatch – although I have a there a Samsung Gear Sport that occasionally I use. In recent years I have tried several models, and I certainly … Read more

A jeweler has found a rolex that gives the date in an unusual language for luxury watches: the Catalan

March 10, 2025 by usatoday24

The sale of high -end watches has become a More investment formthanks to the high value that certain pieces acquire. In recent months, the second -hand watch market has suffered A drastic fall After a pricing bubble derived from the shortage of supply against high demand. That has made this a good time to find Pieces at a good price. The tiktok @jewelrybarcon account, shared The discovery of a curious piece that bought a few days ago: a rolex day-date, also known as Rolex President with very special gold finish. The initial emotion of buying a rolex like that, became surprise to discover that the days of the week that are shown in the sphere were in Catalan, instead of having them in Spanish or English as usual in the Swiss brand watches. Something that in principle could light alarms in front of falsifications. At first, the young man thought this could be a problem if he decided to sell it in the future since the clock would have less demand to be in a different language. However, after an initial investigation he discovered that the story that locked that clock made him a very limited and exclusive piece. The mystery of the Catalan rolex The user explains in his video that it was very strange that a Swiss company like Rolex manufactured a clock in Catalan. The explanation that found that curious finish was that, in reality, a group of Andorra businessmen had asked Rolex to make a special roll with texts in Catalan. This limited edition occurred until 2007, which, according to the young Tiktoker, makes it a very sinned rarity. What initially seemed a possible inconvenience became a distinctive feature that apparently increased its value significantly. Now, your rolex is not only a luxury accessory, but also a collection piece With an interesting story. So far what social networks say. Rolex Day-Date is the most international rolex The reality is that Rolex is an international brand and, within its catalog, the Rolex Day Date, better known as Rolex President, is The most international of all. So much so that it not only has daily dials translated into Spanish or Catalan, but can also be found in Vasco, in Farsi, in Chinese or in Ethiopian. As he points out in his own Rolex’s official pageDay-Date speaks the language of who takes it and, since 1973, it is Available in 26 languages including alphabets in Latin, Arabic, Cyrillic, Hebrew, Japanese, Chinese ideograms and even the ge’ez alfasilabarium used in the horn of Africa. The linguistic peculiarity of Day-Date makes, in reality, the language is not an exceptionality itself because of the fact that a group of Andorran businessmen asked for their watches in the official language of their country. However, it is a distinctive feature, because it is a rolex of a certain year, with a certain finish and with the addition of being in Catalan that is not a highly demanded option. In no case would it be a rare and exclusive piece since anyone can choose the language of the dial with the days of the week when configuring this watch. Its second -hand price can range between 20,000 euros and 45,000 euros according to their status and characteristics.

Bill Gates has a fortune of 107,000 million dollars and his collection of watches is not worth more than $ 100: but they are jewels

March 5, 2025 by usatoday24

The Microsoft co -founder has been one of the richest people in the world for almost four decades, and today It holds a fortune of 107.6 billion dollarsaccording to Forbes. During that time, his taste for watches has been molded. Unlike Mark Zuckerberg, who has directed his collection of watches towards models of more than 1.3 million dollarsGates’ tastes are much more practical. Gates’s watches Rather Collect high -end watches as they usually do The millionairesBill Gates maintains a curious fidelity that goes back several decades ago with a Japanese brand: Casio. This choice reflects its pragmatic approach in terms of meaning that watches have For the millionaire, being an object with a functional end and not as a complement of luxury and ostentation of its wealth. Gates has at least three different models of this Japanese brand, famous for its reliability, durability and a functional design that is again fashionable with the return of the 90s aesthetics. One of the watches that has been seen most on Bill Gates’ wrist is the hard casio, an analog diving clock. One of those occasions was during Your visit to Harvard University In 2018. This model, also known as Casio Marlin MDV-106-1AVstands out for its water resistance (up to 200 meters), with a stainless steel box and black sphere, all for a price less than 70 euros. However, one of Gates’s favorite watches is even more minimalist and sober, betting on a completely black finish. It is the Casio MRW-200H-1B2Va light clock without great pretensions that has LED lighting, long -term battery, water resistance, stopwatch and a price that Round the 20 or 30 eurosdemonstrating that it is not necessary to spend a fortune to have a functional and reliable accessory. Another of the usual models in the Gates wrist is Casio W214H-1AV Illuminator Sports Digital Chrono Watch. Unlike the previous ones, the W214H is completely digital and retains a very marked novelty aesthetic. Its price ranges from the 20 and 30 eurosalthough being an already discontinued model they can only be found in the second -hand market. The “nokia” of the watches Gates’ loyalty for the Japanese brand is not an exception or an exclusive fixation of the millionaire. Casio was one of the most relevant brands in electronic watchmaking in the late 80s and 90s, with such models mythical and indestructible such as F-91Wwhich continues for sale 30 years after its launch. Thanks to that Nostalgic factor Already the extraordinary reliability and simplicity of its watches, the brand has resurfaced strongly in recent years with reissues of its old models for The nostalgic that we have spent much of our life with a casio on the wrist. Some even see it as A future proposal. In Xataka | There is nothing wrong with you comparing you with a casio: how their watches made him a glorious brand Image | Casio, Flickr (Ted Conference)
