THE BIG REVIEW: 5 million

That's how big Wikipedia is, the internet's biggest online encyclopedia and the source for millions of pieces of late-night homework, is. It now has more than 5 million articles in English. The website announced it had passed the milestone on Sunday with an article on Persoonia terminalis - a rare shrub native to eastern Australia. In 14 years, Wikipedia has racked up around 3 billion words, 18 million references, and 30 terabytes of data - equivalent to 510,000 hours of 128 kB/s audio. At 300 words per minute, it would take more than 19 years of non-stop reading to read Wikipedia in its entirety. However, it is still nowhere near a level that would see it cover all human knowledge, according to estimates. More than 104 million articles would be needed to cover the total range of the human race's information according to Wikipedia user "emijrp", who is running a project to find such an estimate. Here's to the next five million.
