The most important thing that the Renaissance left us was not Michelangelo’s ‘David’ or Botticelli’s ‘Spring’: it was ice cream

From the classic flavors to the most baroque derivatives such as “tripe flavored with oreo and kinder”. For many the king of sweets, the ice cream It has a history dating back to the Italian Renaissance. It is true that the story of “ice with things” almost starts from the beginnings of civilization. The ancient Greeks, the Persians and the Chinese already mastered the art of cooling off using crushed ice mixed with fruits, honey or juice, a precursor to what we would currently consider a sorbet, which differs from ice cream in that it does not contain buttery ingredients. Like all things that have been done since time immemorial, it is not very clear how the idea came to Italywhether from China through the Silk Road or through Sicily thanks to Arab influence. From the distant antecedents to Italy What we do know is that ice cream became popular in Europe thanks to Cosimo I de’ Medicione of the key figures of the 16th century (not to be confused with Cosimo de’ Medici simply, founder of the dynasty and popularly known as Cosimo the Elder because it was not a question of heating his helmets too much is the nickname). Cosimo I took power in 1537becoming Grand Duke and boss of Florence at the age of 17. Cosimo decided to make his own that “the best mayor, the king” and, in addition to carrying out a successful economic and military policy, he completely renewed the Florentine administration (basically concentrating all the power in his hands) and promoted the flourishing of sciences and arts in the city (we owe him, for example, the construction of the Gallery Uffizi). And Cosimo I would end up going down in history, above all, as a great patron who welcomed and financed painters, sculptors, architects, astronomers and a very long etc. One of them would be Bernardo Buontalentiinventor, architect, set designer, designer, engineer and all-rounder at the Florentine court. Apparently, some guests from the Spanish court showed up by surpriseso Cosimo commissioned Buontalenti (who designed a fortress that made you a dessert) something to surprise the Spaniards during the welcome banquet. Buontalenti had already managed to preserve the snow which they brought from the mountains in underground chambers insulated with wood and cork, so a dessert was made by mixing snow with milk, eggs, lemon, orange, bergamot and sweetening it with honey or sugar (versions differ). Of course, that was a great success and at the Florentine court there began to be cakes to try the prodigious invention. Today, the largest festival in Europe dedicated to ice cream It is celebrated every year in the city of Florence, where in addition to Buontalenti, they also honor Ruggeria chicken peddler who a few years before Buontalenti himself had won a cooking contest presenting a dessert made from snow and frozen fruit. Italy, cradle of modern civilization. Next stop, France For some reason that no one in their right mind could explain, the Spanish did not have the good sense to take the recipe home and it is in France where the next chapter in the history of ice cream takes place. Catherine de’ Medicirelative of Cosimo I (try to trace the relationship in the family treeif you can) married Henry II of Orleans in 1533, thus becoming queen of France in one of the most turbulent periods in its history. She was queen consort until the death of her husband, with whom she did not get along at all, and then queen regent when her son Francisco II was still very young, who also had very fragile health and who died shortly after due to otitis. “And doesn’t it make you ice cream?” Paul Emil Jacobs, circa 1840. Thus, Catherine became regent for her second son, Charles IX, ruling for ten years until he finally took possession of the crown. However, Catherine would also survive Charles, thus becoming an advisor to Henry III, his third son and next king of France. Maybe Catherine remind you of someone. Returning to the topic at hand, Catherine, in addition to being a political animal, was, like Cosimo I, a convinced humanist and a great patron of letters and the arts (sponsoring, for example, the construction of the Tuileries). Catherine promoted the arts in France but did not forget her Italian roots, so the influence of elements italians at the French court it was notable. Thanks to Catherine, ballet was introduced to France and she was also partly responsible for the popularization of the commedia dell’artealthough it was not the first to present it in the French country. Catherine de’ Medici is a total fan of French gastronomy. François Clouet, before 1559. In more prosaic considerations, he also decided that French cuisine was a disaster and filled the court with Italian cooks, bringing ingredients such as olive oil, artichokes, beans, anchovies, pasta and much more. Besides taught the French to use the forkry, of course, made ice cream fashionable. And he did it by nothing more and nothing less than taking Ruggeri, the chicken man turned cook, to the French court. Tremendous plot twist. From the French court to heaven During the decades and centuries that followed, the expansion of ice cream is unstoppable (how could it not be?). In 1686, Francesco Procopio dei Coltelli moved from Palermo to Paris and opened the Café Procope, considered the oldest in France and where coffee and ice cream were served and names of the stature of Rousseau, Voltaire, Diderot, Balzac, Victor Hugo, George Sand, Napoleon Bonaparte and even Oscar Wilde, who liked to go to France from time to time to do his things, gathered to have a cone. If you are interested, you can still go have a drink. Throughout the 17th century, numerous gastronomy books were published that included the recipe for the famous Italian ice cream, and at the end of the 19th century, Italian immigrants introduced the recipe to New York (the Americans, in turn, would … Read more

China’s nuclear renaissance is now visible from space

Since China detonated its first atomic bomb In the midst of the Cold War, its relationship with nuclear matters has been marked by secrecy, declared prudence and a deep distrust of the great powers. For decades it chose to stay in the background, building capabilities away from the spotlight and speaking little about them. This historical silence is key to understanding why, each time that something moves In that area, the world pays attention. A silent resurgence in the mountains. The story was brought in a special the new york times this weekend through satellite images. In the humid and rugged valleys of Sichuan, far from prying eyes, China is reactivating and expanding a nuclear infrastructure conceived for another era but adapted to a rivalry between superpowers that is intensifying again after the end of the historic pact between Moscow and Washington that we counted recently. Images from space show new bunkers, ramps and industrial complexes with ventilation and thermal dissipation systems that aim to high risk activitiesintegrated into a framework that no longer seems defensive or residual, but rather coherent with an accelerated and planned expansion that has been gaining pace since the end of the last decade. The inheritance of the “Third Line” and its update. These enclaves are not born from nothing, but sink their roots in what was called lto “Third Line”promoted by Mao Zedong to protect the nuclear heart of the country from American or Soviet attacks. For decades, that internal nuclear empire remained in the backgroundreduced and fragmented when global tensions eased. Today, those same facilities seem regain prominencenot as relics, but as modernized nodes that recover their central function in a China that has left behind the doctrine of minimum containment. Zitong in 2022 (top) and 2026 (bottom) Zitong and Pingtong: key pieces. They explained in the Times that the work detected in Zitong suggests advanced testing of high-precision explosives, essential to perfect the implosion that initiates a nuclear reaction, while the Pingtong complex, with its large ventilation chimney and its characteristic architecture, points to the manufacture of metal cores of the warheads, probably plutonium. The structural similarity with foreign facilities specialized in this process, like Los Alamos National Laboratory, reinforces the idea that China is closing the full cycle of design, testing and production of modern nuclear weapons. Intelligence, data and the value of what is not seen. Beyond the visible, the real leap is in the integration of intelligence, geospatial analysis and advanced simulation capabilities. The great laser ignition laboratory in Mianyang allows the behavior of nuclear warheads to be studied without the need for actual detonations, an approach that reduces political and environmental risks while accelerating technical refinement. In this way, each work detected is only a fragment, but together they form a mosaic that reveals a strategy based on accumulating knowledge, validating designs and gaining operational confidence without openly crossing international red lines. A direct challenge to gun control. There has been a lot of talk about these in recent weeks with the end of the New Start treaty. This Chinese acceleration would complicate any attempt to revive global nuclear control agreements after the expiration of that last treaty between the United States and Russia. Washington insists that China must form part of any new framework, but Beijing avoids commitments that limit growth that it considers necessary for its status as a global power. The American accusations of covert tests, rejected by China, add a layer of mistrust that pushes both sides to plan based on worst-case scenarios. Taiwan and the logic of enhanced deterrence. The backdrop to this effort is China’s perception of vulnerability to nuclear coercion American, especially in a plausible crisis over Taiwan. As? A largest arsenaldiverse and technologically tuned offers Beijing the feeling of sufficient immunity to maneuver more freely in a conventional conflictraising calculation risks for all parties. In that sense, what is happening under the mountains of Sichuan is not only an industrial modernization, but rather points more to a strategic bet that redefines the balance and forces the rest of the world to interpret, and the “intimate enemies” to react, if They are not doing it anymore.

The renaissance of nuclear energy is underway. And the microreactors are preparing to give it a boost

The physicists and engineers involved in the development of fourth generation nuclear fission reactors They are working to propose new designs that conceptually may be very different from those of previous generations. Of course, the requirements that these new nuclear power plants must meet are clearly defined. The first of them consists of achieving the maximum possible sustainability, so that the fuel is used to the maximum to produce energy, the amount of radioactive waste resulting from the process is minimized and its management is as efficient as possible. The second requirement concerns the economic investment that must be made to start up and maintain the nuclear power plant, which must be as low as possible so that it can be compared to the expenditure required by other sources of energy, thus reducing the risk. financial. And the third and final requirement stipulates that safety and reliability must be high enough to minimize the probability of damage to the reactor core. Besides, if an accident occurred It should not be necessary to take emergency measures beyond the nuclear power plant facilities. Westinghouse and Radiant working on the world’s smallest reactors The International Atomic Energy Agency (IAEA) published a very detailed report in September 2024 entitled “Energy, electricity and nuclear power estimates for the period up to 2050”. In it, it analyzes the short and medium-term future of nuclear energy and delves into its role as a means of generating electricity that can contribute to the achievement of global climate objectives. However, the most interesting thing is that this organization predicts that global nuclear power will increase by 2.5 by 2050. Microreactors use uranium-based isotropic tristructural particles as fuel Compact and modular nuclear reactors play a crucial role in achieving that vision, but microreactors will also likely play a very important role. As their name indicates, they are compact and modular nuclear reactors much smaller than conventional fission machines. As we can predict, they produce less energy than the latter, usually 50 megawatts or lessbut thanks to their size they can be installed in remote places where it is not possible to set up a traditional nuclear power plant. However, nuclear microreactors have more advantages. On the one hand, its installation is relatively simple and much faster than that of conventional reactors. In addition, they do not require large water cooling systems, they operate in an automated manner and their maintenance is simpler than that of a traditional nuclear plant. And, interestingly, the eVinci and Kaleidos microreactors being developed by the American companies Westinghouse and Radiant use uranium-based tristructural isotropic particles (TRISO) as fuel. The particles of this fuel are the size of a poppy seed and contain uranium, carbon and oxygen encapsulated in a carbon-ceramic shell that is capable of withstanding extreme temperatures. On paper this nuclear fuel is the most robust ever developed to date. An interesting note: Radiant uses helium as a coolant, while Westinghouse uses a passive heat duct system. These two companies have the financial support of the US Department of Energy (DOE) and plan to place their microreactors on the market in 2030 as long as, of course, they obtain a license from the Nuclear Regulatory Commission (NRC).
