Here's the Most Cited Academic Paper on Wikipedia

Many people use Wikipedia as their main source of knowledge for just about any topic imaginable. But is there one source that Wikipedia draws from more than any other? The answer is yes.

An analysis by the Wikimedia Foundation found that the most cited academic paper on Wikipedia is called "Updated world map of the Köppen-Geiger climate classification." The paper has been cited an incredible 2.8 MILLION times on Wikipedia. To put it in perspective, the second most cited academic paper, "Prediction of Hydrophobic (Lipophilic) Properties of Small Organic Molecules Using Fragment Methods," has only been cited 21,350 times.

The climate classification map is simply a map of the world showing what climate each area of the world is. While that may not sound super sexy, climate can affect everything from sociology to biology to just about anything, so it's incredibly relevant to many topics of study. It's also helpful in helping people creating travel guides.

If you're interested, here's the actual climate classification map:

If you thought that was weird, two of the top 10 most cited papers included "Catalog of Fishes" and "A Concise History of Romania," which we're not sure why so many articles would be citing the history of Romania, but there you go.

Derived from the part of the cannabis plant that doesn't get you “high” like THC, cannabidiol (CBD) is typically used for health reasons instead of for recreational purposes, and has been found to be especially useful for treating symptoms of Parkinson’s disease. A challenging neurodegenerative disorder, Parkinson’s causes a combination of motor and non-motor symptoms — such as tremors, weakness, stiffness, dizziness, anxiety and sleeplessness — that affect daily life. CBD, typically taken in oil form, has the potential to relieve these symptoms, improving sleep, reducing inflammation and more, which can profoundly help the more than 10 million people across the world suffering.
