Akpan's Slide LibraryAkpan 的切片库
An ant, a mosquito wing, pollen, a fish gill, a slice of tomato: fourteen classic biology slides, scanned edge to edge so you can zoom from the whole slide down to single cells on a phone or a laptop. It exists, and it is very nice.
一只蚂蚁、一片蚊子翅膀、花粉、鱼鳃、一片番茄：十四张经典生物切片，从头扫到尾，用手机或电脑就能从整张切片一路放大到单个细胞。它一直都在，而且很好看。
Why it has his name为什么用他的名字
Named after Akpan Friday以 Akpan Friday 命名
In February 2019, Akpan Friday, then a first-year microbiology student at the University of Abuja in Nigeria, explained that most students around him never get to use a real microscope. They learn microbiology from drawings.
2019 年 2 月，当时在尼日利亚阿布贾大学读微生物学一年级的 Akpan Friday 说，他身边大多数学生从来没用过真正的显微镜，只能对着图画学微生物。
The first attempt to help failed. Whole-slide images were shared, but the viewer needed a far more powerful computer than his university had, and despite trying very hard he couldn't get it to run. He kept helping anyway: he explained what students in Africa were up against, visited two primary schools to talk with teachers and wrote to the Local Education Authority.
第一次尝试失败了。全切片图像发过去了，可是看图软件需要的电脑比他学校里的强太多，他非常努力也没能跑起来。但他没有停下：他讲清楚非洲学生面对的难处，去两所小学和老师交流，还给地方教育局写信。
About five months later, a viewer that runs in any web browser solved it: the whole collection went online, readable on any device. The collection was named after Akpan, as thanks and to encourage his dream of becoming a microbiologist. He went on to found the X-WOW Kids Science Club.
大约五个月后，一个在任何浏览器里都能用的看图工具解决了问题：整套切片放上网，什么设备都能看。这套切片以 Akpan 命名，既是感谢，也鼓励他成为微生物学家的梦想。后来，他创办了 X-WOW 儿童科学俱乐部。

Akpan Friday: the reason this exists, and its namesake. As the old site put it, without his help none of this would have happened.
Akpan Friday：这套切片存在的理由，也是它的名字。正如旧网站所说，没有他的帮助，这一切都不会发生。

Pick a slide and zoom挑一张，放大看
Each link opens the full scan in your browser: pinch or scroll to zoom from the whole slide down to single cells. Sizes are the full-resolution image in pixels, read from the image host.
每个链接都会在浏览器里打开完整扫描：用两指或滚轮，从整张切片一路放大到单个细胞。尺寸是原图的像素数，读自图片托管网站。
Uploaded to the image host between 2018-12-17 and 2019-07-24. Together: 3.2 billion pixels.
上传到图片托管网站的时间：2018-12-17 至 2019-07-24。加起来约 32 亿像素。
Where the slides live切片放在哪里
Off the old site, still online不在旧网站上，所以还在线
The scans were never stored on the old website. They sit on EasyZoom under the X-WOW account, and the old pages only framed them, which is why they survive the move to this site. The one dependency left is that account: if it ever closes, these links stop working.
这些扫描图从来没存在旧网站上。它们放在 EasyZoom 的 X-WOW 账号下，旧网页只是把它们嵌了进来，所以网站搬家后它们还在。剩下唯一的依赖就是这个账号：哪天账号关了，这些链接就失效了。
Want slides like these for your own class? A microscope with a camera and stitching software can make them; the Slide Scanner page says where to get one today.
