Today's Google Doodle celebrates what would have been Muslim philosopher Ibn Sina's 1038th birthday.

Sina is widely regarded as one of the most significant figures of the Islamic Golden Age and made foundation-forming breakthroughs in medicine.

Here's everything you need to know about why Ibn Sina is important, plus his greatest achievements and quotes:

Who is Ibn Sina?

Sina grew up in Afšana, a village near Bukhara, near what we now know as Uzbekistan.

Sina was a polymath (meaning he was an expert in a variety of different fields) and learnt arithmetic and taught himself physics and other philosophies by studying Aristotle.

He began studying medicine at the age of 16 and went on to pen over 131 books.

What were Ibn Sina's biggest achievements?

Sina's most influential book out of the many he wrote is Al Qanun fil-Tibb, or 'The Canon of Medicine.'

It was the first work to identify contagious diseases such as Tuberculosis, and quickly became an essential text in European medicine after being translated.

It's now credited as helping to form the foundations for modern Western medicine.

What were some of his most inspirational quotes?

Having written as many books as Ibn Sina has, you can expect him to have more than a few stirring quotes. Here are some of his best:

"The world is divided into men who have wit and no religion and men who have religion and no wit"

"The knowledge of anything, since all sins have causes, is not acquired to complete unless it is known by its causes."

"The more brilliant the lighting, the quicker it disappears."

"Medicine considers the human body as to the means by which it is cured and by which it is driven away from health."
