There are 500 years (1452-1519 Leonardo Da Vinci) recorded ideas on vortex on the basis of his experiments with water. In fact, the theme of water hydrology and hydraulics consists of a large part of the study of the life of Leonardo. As a matter of historical note, more than the messages Leonardo da Vinci were dedicated to water issues than any other subject. The existence of water and eddies intrigued Da Vinci which led to speculate on the existence and behavior of vortices in the air and the cosmos. The power and importance of eddies in water has also led to study closely the behavior of water under different conditions.

The fascination with Da Vinci and the fluid dynamic vortex through his art with the movement of water flow and the vortices which is expressed in his paintings and sculptures.

The existence and behavior of bubbles in water was also interest for Da Vinci, from which it took note of the close observation bubbles in the water in a spiral motion. In his notes written in the Codex Leicester Folio 23V (now owned by Bill Gates), noted that " Moving water is always moving in a circle on the surface bottom. "

Da Vinci spent many years in his makeshift laboratory and field observation of movements of water and air. To visualize the fluid dynamics of water at work, she has experimented with tanks glass to see the movement of water flow in different scenarios. During his fieldwork, took detailed notes and drawings to record their experiences and observations.

To aid his research, he invented a water gate that the pressure of water use to create an airtight seal. Contingencies by Da Vinci in the time of their experience and detailed technical drawings of this water is going to survive over time and possibly be used in the design of the locks of the Panama Canal.

Sometimes the spirit of Da Vinci reflect on the many kingdoms water bodies, as their comments often caused by writing ideas. As a habit, he write or draw these thoughts, along the margins of your documents while working on other issues. A series of these notes in the upper right corner of one of his papers provide us with your outline of a draft treaty on water. It was divided into fifteen books, each book that addresses a different aspect of water:

1. Water itself

2. Del Mar

3. Veins

4. De los Rios

5. From the nature of the fund

6. Subject

7. Several types of gravel

8. Surface water

9. Make a difference in her

10. Rio Repairs

11. Pipeline

12. Channels

13. Machines turned by water

14. Water boarding

15. Things to wear by the water

Being given the many activities involved Leonardo never found the time to complete this series of books on water. His writings, particular the Codex Leicester, contain numerous references and short notes to include in these books. An example of this can be found in his note on Precipitation: record how clouds are formed and how they dissolve, and this leads to water vapor in rising air, Earth and the cause of the mist and the air thicker, and why it seems more blue or less blue, the same time as another. Type in the same way regions of the air due to snow and hail, and how water shrinks and hardens into ice and new forms forms Snow air. "

Another field observations of Da Vinci explored the physical expression of the principle of large-scale vortex. Your written comments on a waterspout was along the shore were registered on a page entitled "The movement by wind and water-related turmoil. As indicated in the inimitable words Da Vinci:

Often, when the wind meets another at an obtuse angle, the two winds circle around the car and twine themselves as a huge column, and becoming condensed, air, gain weight. Once I saw the winds, swept together, producing a hole in the sand of the sea as deep as the height of a man, removing the stones of considerable size and transporting sand and algae if the air space of a mile and launching, turning around and transforming it into a thick column, which forms dense dark clouds that point.

Many people will probably never see a waterspout land on the coast all his life, but thanks to Da Vinci and detailed notes from long ago, we can appreciate the sense of such experience.
