Boulders Beach

Boulders Beach

Boulders Beach is a sheltered beach made up of inlets between granite boulders, from which the name originated. It is located in the Cape Peninsula, near Simon's Town towards Cape Point, near Cape Town in the Western Cape province of South Africa. It is also commonly known as Boulders Bay. It is a popular tourist spot because of a colony of African penguins which settled there in 1982. Boulders Beach forms part of the Table Mountain National Park. These African penguins are only found on the coastlines of Southern Africa -. These penguins are currently on the verge of extinction. As a result, the penguins are under the protection of the Cape Nature Conservation. Although set in the midst of a residential area, it is one of the few sites where this vulnerable bird can be observed at close range, wandering freely in a protected natural environment. From just two breeding pairs in 1982, the penguin colony has grown to about 3,000 birds in recent years. This is partly due to the reduction in commercial pelagic trawling in False Bay, which has increased the supply of pilchards and anchovy, which form part of the penguins' diet.

Experimento de Geiger-Marsden

Experimento de Geiger-Marsden

O experimento de Geiger–Marsden, também conhecido como experimento da folha de ouro ou experimento de Rutherford, foi uma experiência científica realizada por Hans Geiger e Ernest Marsden em 1909 com o objetivo de investigar a estrutura do átomo. O experimento foi realizado sob a supervisão de Ernest Rutherford nos laboratórios de Física da Universidade de Manchester, no Reino Unido. Os resultados do experimento demonstraram pela primeira vez a existência do núcleo atômico, o que não era consistente com o modelo atômico de Thomson, proposto em 1904 por Joseph John Thomson. O experimento de Rutherford consistiu em um feixe de partículas alfa gerados pelo decaimento radioativo do radônio, normalmente executado em uma folha de ouro muito fina em uma câmara evacuada.

居酒屋又稱酒館,是提供酒類和飯菜的料理店。與只提供酒類為中心點的普通酒館不同,居酒屋提供比較有質量的飯菜,但卻不同於小吃店。居酒屋是具有日本特色的飲食店。不過,在其他國家也有類似的酒館,能方便地吃飯、提供酒水。有時居酒屋亦譯作bar。
