[Google Doodle] Julius Richard Petri 培養皿發明人 160歲誕辰

還記得學生時代做實驗時，會使用一個玻璃小圓盤，來培養一些微生物與小型植物，這小圓盤由一個平面圓盤狀的底和一個蓋組成，英文稱他為Petri dish，而名字由來與今天的Google Doodle很有關係。 今天的Google Doodle就是由剛剛所說的Petri dish 培養皿所構成，而2013年5月31日就是培養皿的發明人Julius Richard Petri 160歲誕辰紀念，而培養皿就是以他的姓作為命名。

 Julius Richard Petri 於1852年5月31日的德國出生，他一開始在Kaiser-Wilhelm-Academy for Military Physicians (1871–1875) 學習醫學，並於1876年拿到學位。後來又在柏林的Charité Hospital繼續研究，直到1882年開始從事軍醫工作。而這個生物學與醫學很重要的實驗器具 培養皿，就是在1887所設計發明。

 一般來說培養皿使用前都必須滅菌消毒，大多利用高溫高壓來進行，由於有了Petri dish的設計，可讓醫學與生物學可以有更方便的實驗器具可使用，在發明人Julius Richard Petri 160歲誕辰的這一天，我們一起來緬懷他。

Google is celebrating the 161st birth anniversary of Julius Richard Petri, who invented petri dish, with a doodle on its home page. The doodle features six petri dishes which are swabbed by a hand showing images of bacteria grow and spread in the dishes.

The six petri dishes which when one clicks on the play button are swabbed by a hand. These bacteria go on to form the alphabeths that spell Google.

Born on May 31, 1852, Petri studied medicine at the Kaiser-Wilhelm-Academy for Military Physicians in Berlin. He later worked at the Imperial Health Office with Robert Koch who is considered the father of modern bacteriology.

Petri is known to have invented the petri dish in the year 1877 when he was working as an assistant to Robert. He was not the first to use agar to culture bacteria, but he is credited to have invented the standard dish in which it was done. The petri dish allowed for the better identification of bacteria and the diseases they caused.

Petri dishes later moved from the laboratory to classrooms where they are used by every student of biology for various experiments. They are used everywhere from school labs for conducting experiments by students to research facilities where they're used by bacteriologists and other scientists.

The invention paved the way for further research allowing scientists to identify microbes that cause diseases.

Julius Richard Petri died on December 20, 1921.
