干渉計「Virgo」は、重力波を検出するための世界で最も大きく、最も感度の高い科学機器の1つです。イタリアのピサ県カッシーナにあり、欧州重力天文台（EGO）内に位置しています。 これとは何か、そしてどのように機能するか この実験は、それぞれ3キロメートルの長さを持つ2つの垂直なアームを備えた、印象的なマイケルソン干渉計です。 レーザー：レーザー光線は特殊なミラー（ビームスプリッター）によって半分に分割され、2つのアームに沿って送られます。 ミラー： 各アームの終端にある非常に高精度のミラーが、光を反射して戻します。 重力波： （ブラックホールの合体のような壊滅的な出来事によって生成される）重力波が装置を通過すると、時空が歪みます。これにより、一方のアームがわずかに伸び、もう一方のアームが縮みます。 真空： 空気との干渉を防ぐため、ビームは超高真空レベルが作成されたチューブ内を伝播します。 EGGO天文台 欧州重力天文台（EGO）は、Virgoのインフラストラクチャを管理するイタリアとフランスのコンソーシアムです。2000年にINFN（国立核物理学研究所）とフランスのCNRSによって設立されました。現在、科学協力には多数のヨーロッパ諸国の科学者が参加しています。

The Parish Church of San Martino: Architectural Highlights Perched on a tuff spur opposite the village, and separated from it by a deep escarpment, the parish church is unique because it is predominantly built of terracotta (the façade is stone), like most medieval parish churches in Tuscany. The construction of the parish church dates back to the second half of the 13th century, when a new parish church was created, detached from the previous parish church of San Gervasio. The Interior Of grandiose proportions, the parish church appears to have a rather uniform masonry, despite having been restored several times over the centuries. According to studies conducted on its architectural structure, different periods of construction appear to coexist. Nevertheless, the most striking style is late Romanesque. The interior consists of three naves of five bays with brick columns, a raised presbytery, and three side chapels. Inside, there is also a hexagonal baptismal font, a holy water stoup, and a large marble basin. The latter, destroyed in the 17th century, was presumably used for the immersion baptismal rite and came from the church of Santa Maria da Ripezzano, near Palaia. The parish church is also a scenic location for ceremonies and weddings. https://www.terredipisa.it/attrazione/palaia-pieve-san-martino/

EGO, the European Gravitational Observatory, located in Cascina, in the Pisan countryside, is the institutional headquarters of the Virgo experiment, the only gravitational wave detector in Europe and one of four in the world. Gravitational waves are very faint cosmic signals that allow us to observe extraordinary phenomena in the deep Universe, such as the merging of black holes or stars. https://www.ego-gw.it/mission/ Book a guided tour, remotely or in person VISIT EGO & THE VIRGO INTERFEROMETER

A medieval town with charming streets and climbs. Buildings full of history.

Long straight on flat ground. Recommended? I don't know….

The historic town center is always worth a stop!

Lari is a town located in the Pisan hills, whose economy is mainly agricultural. Among the fruit production of its territory, the cherry stands out. The whole area, in fact, is famous not only for the large quantity of cherries produced (half of the whole of Tuscany), but also for their variety and renowned quality, so much so that the DOP (i.e. PDO, protected designation of origin) , was requested with the name "Ciliegia di Lari". The biodiversity and quality of the cherries of the Pisan hills is due not only to the peculiarities of the soils and the climate, but also to the knowledge and experience gained over time by the numerous agricultural producers in the wake of tradition. Every year between May and June, in the historic center of Lari there is a Cherry Festival (and local food and wine products) accompanied by cultural and folkloristic events. An opportunity not to be missed!

Lari is famous for its Castello dei Vicari, located at the top of the hill and in the center of the city. This interesting fortress was started around the year 1000 in a strategic point of the Arno valley and grew in splendor until 1400, when it began to host the Vicars, i.e. the magistrates who had the task of administering a large part of the Pisan territory on behalf of the Grand Duke of Tuscany. Today, after being restored, it is open to the public and hosts conferences, meetings and exhibitions, as well as guided tours, entertainment, concerts, theater, wedding ceremonies and other initiatives for groups and school parties.
