It’s an exciting year for Slovenia’s Postojna Cave. The karst cave system known as the “Underground Grand Canyon” is currently celebrating its 200th anniversary. In addition to that, the cave’s baby dragons got official stamps in honor of their 250th anniversary.

Josephus Nicolaus Laurenti is credited for giving the “baby dragons” their binomial name Proteus anguinus. Locals also call the aquatic salamander “human fish”. The olm is the largest known cave-dwelling animal and can live for over half a century. They live exclusively in Postojna Cave and cannot be found elsewhere.

Postojna Cave was first discovered in 1818 and is the only known home for Proteus anguinus or "baby dragons".

Although Proteus anguinus was given its binomial name in 1768, it wasn’t until 1818 that a local Luka Čeč discovered what would be called Postojna Cave.

The olm has good reason to live solely in the cave system. Postojna Cave is one of Slovenia’s top tourist spots due to its resemblance to the Mines of Moria in Lord of the Rings. Not surprisingly, the cave is currently a protected UNESCO World Heritage site. Conservationists are currently working to protect the “baby dragons” to ensureb the species’ survival.

The Proteus anguinus or "baby dragons" have been synonymous to Postojna Cave and are an important part of the cave's fragile ecosystem.

Slovenia certainly appreciates its rare “baby dragons”. Pošta Slovenije has just unveiled 25 new stamps featuring Proteus anguinus in celebration of the olm’s 250th anniversary. The “human fish” stamps are available for 1.77 euros.

Unfortunately, the stamps are only available in Slovenia.

Luka Čeč was the first to discover Postojna Cave in 1818. The local lamplighter found a stunning new area while surveying the karst cave system.

Postojna Cave has turned into a tourist spot since then, boasting of thousands of visitors annually.

The tourists regularly look for Brilliant, Postojna Cave’s pale symbol as well as the Concert Hall with its exceptional acoustics. Lucky visitors might even get a glimpse of the “baby dragons” that reside in the cave.

Postojna Cave has played host to several celebrated guests. Emperor Francis I of Austria and his wife, Empress Consort Caroline Augusta were the first royal visitors in 1809. Benito Mussolini also visited the cave during his free time.

We are saved!




Words, without context, can often mislead us. What more in the case of homophones, words pronounced alike but very much different in meaning, origin and spelling.

Bruce Worden, a Science Illustrator, Comic Book Creator and self-confessed grammar nerd, embarked on a visual exploration of words that sound so much alike, people often get them wrong. Five years in the making, his blog-turned-book “Homophones, Weakly” is a collection of 300 sets of homophones. And now that is has been released for public consumption, people are thanking him for it. Who wouldn’t?

39 ‘Same’ Things That You Probably Don’t Realize Are Different

Know the differences to stop the confusion.




Let's admit it; nobody wants to be corrected by anyone. Whether the one who gave the correction means well or not, it still is not widely accepted to correct other people. However, some people are like walking signboards that say "correct me" wherever they go.

It gets hard not to say a word when the error gets repeated a lot. A great example of this is the most commonly mispronounced words that are screaming banners on people to dare their friends to correct them. Others are words that you think are the same but actually aren't, like these:
