you may keep saying in your head "wow!". well! YOU SHOULD! 
Because i will present to you the most expensive  book in the whole world. so enjoy!

let's start with a picture here! 

and yes this is the book i told you about. this is Codex Leicester!

   The Codex Leicester (Or Codex Hammer) is a collection of famous scientific writings by Leonardo da Vinci. The Codex is named after Thomas Coke, later created Earl of Leicester, who purchased it in 1719. Of Leonardo's 30 scientific journals, the Codex may be the most famous of all. The manuscript currently holds the record for the second highest sale price of any book, as it was sold to Bill Gates at Christie's auction house on 11 November 1994 in New York for US$30,802,500. Equivalent to US$50,367,540.19 in July 2017.
The Codex provides an insight into the inquiring mind of the definitive Renaissance artist, scientist and thinker as well as an exceptional illustration of the link between art and science and the creativity of the scientific process.

Hold on a sec! who bought it ?? - Bill Gates ?

What is this book talking about? 
   The manuscript does not take the form of a single linear script, but is rather a mixture of Leonardo's observations and theories on astronomy; the properties of water, rocks, and fossils; air, and celestial light. The topics addressed include:
  • an explanation of why fossils can be found on mountains. Hundreds of years before plate tectonics became accepted scientific theory, Leonardo believed that mountains had previously formed sea beds, which were gradually lifted until they formed mountains.
  • the movement of water. This is the main topic of the Leicester Codex. Among other things, Leonardo wrote about the flow of water in rivers, and how it is affected by different obstacles put in its way. From his observations he made recommendations about bridge construction and erosion.
  • the luminosity of the moon. Leonardo speculated that the moon's surface is covered by water, which reflects light from the sun. In this model, waves on the water's surface cause the light to be reflected in many directions, explaining why the moon is not as bright as the sun. Leonardo explained that the pale glow on the dark portion of the crescent moon is caused by sunlight reflected from the Earth. Thus, he described the phenomenon of planetshine one hundred years before the German astronomer Johannes Kepler proved it.

How many pages ?

   The Codex consists of 18 sheets of paper, each folded in half and written on both sides, forming the complete 72-page document. At one time the sheets were bound together, but they are now displayed separately. It was handwritten in Italian by Leonardo, using his characteristic mirror writing, and supported by copious drawings and diagrams.

Where traveld?

The Codex Leicester has been unbound with each page individually mounted between glass panes. It is put on public display once a year in a different city around the world. In 2000, it was displayed at Sydney's Powerhouse Museum. In 2004, it was exhibited in the Château de Chambord, and in 2005 in Tokyo. One page was exhibited at the Seattle Museum of Flight's 2006 exhibit "Leonardo da Vinci: Man, Inventor, Genius". From June to August 2007, the Codex was the centerpiece of a two-month exhibition hosted by the Chester Beatty Library in DublinIreland. The Codex was on view at the Phoenix Art Museum in Phoenix, Arizona from January 24, 2015 through April 12, 2015 for the exhibition Leonardo Da Vinci's Codex Leicester and the Power of Observation. Its presentation at Phoenix Art Museum was the first time a work by the hand of Leonardo himself was on view in Arizona. The Codex was then on view at the Minneapolis Institute of Arts in an exhibition Leonardo Da Vinci, the Codex Leicester, and the Creative Mind that opened June 21, 2015, where it remained on display until August 30, 2015. As part of the same tour, the Codex Leicester was also on display at the North Carolina Museum of Art in Raleigh, North Carolina from October 31, 2015 to January 17, 2016.
