10 MEXICAN INVENTIONS

1. Contraceptive pill

In 1951, Mexican scientists Luis Miramontes and George Rosenkranz, along with the American Carl Djerassi, analyzed the chemical properties of a tuber called Dioscoreamexicana and obtained a substance norethindrone name, can stop the process of ovulation.

Norethindrone became the basis of various treatments. Their contribution has beenranked as one of the most important inventions of the twentieth century, and the names of the scientists involved were now immortalized in institutes and awards. 

2. Linux JarroNegro

JarroNegro is a distro completely Mexican, from the language, through its file storagesystem, to its logo, created by cartoonist Mexican Bachan.

This version of Linux was created by a group of students from the College of Sciences and Humanities Naucalpan in 2005.

Over time, the operating system has captured a developer base that may shape thecollective Mexican first invention to the world. 

3. Kuroshio Current

In 1565, a friar named Andres de Urdaneta was sent by the Emperor Philip II to command an expedition to the Philippines. Once there, he sought the way back.

Between July and October, the ship sailed north to find a stream to take him back toAcapulco.

Urdaneta found a maritime power due to America, almost against Japan. This current,named later as Kuroshio current Japanese black-allowed to go home and draw the paththey would travel warships and commerce that cross the Pacific in the nineteenth century, including the legendary Nao of China. 

4. sound 13

In the late nineteenth century, the technology used in music was virtually nil. The electronics that enables microphones and synthesizers did not exist and hardlyperformed experimental music recordings.

This was no problem for Julian Carrillo, a musician potosino one night in 1895 decided to experiment with new sounds with his guitar, with a knife pressing the strings.

So, he discovered that it was possible to go beyond the traditional 12-note musicalscale, creating sounds in between.

Carrillo died in 1965 almost unknown, but his work endured oblivion and supported bydigital technology, new musicians rediscovering the possibilities of sound. 

5. mechanical tortilla 

When we take a package of tortillas at the store shelf, we ignore that until the earlytwentieth century, the manufacture of this food was an exhausting process: each tortillawas done manually and the fire is lit with wood or coal, a task that occupied the womenfrom before dawn.

From the late eighteenth century, inventors sought to automate the production of tortillasand corn milling of, but requiring complex mechanisms were in some way human hands.

In the 1940s, Fausto Celorio began working on a model that automatically tortilla couldmake the whole process, allowing industrialize the production and ensure the survival of the food.

6. Color TV 

With the official name of "trichromatic system sequence of fields, using the primary colors, red, green and blue for the capture and reproduction of images," GuillermoGonzález Camarena became the most famous Mexican inventor of our history.

At just 22 years old patented the color TV system. Few people know that the development of his invention was funded by the royalties he got from a popular songcomposed by him, entitled Rio Colorado, and also founded one of the first factories of televisions under the name Majestic.

Camarena's legacy lives on every color TV that is built into the world and in the letters of the station founded in 1952 XHGC, Channel 5. 

7. Nixtamalization corn 

If Mexico has hosted great civilizations has been largely due to corn.

Archaeologists have found that around 1000 BC discovered a chemical process (boil theseeds in water with lime and allowed to stand several hours) that not only allowed to make corn dough to make tortillas, but the proteins they became digestible and nutritious.

Brainchild of unknown ancestry, in corn (from the Nahuatl words nextli, ash and tamalli,corn dough) allowed the emergence of the great cities of Teotihuacan, Tenochtitlan and later, a nation whose food culture is part . 

8.Nanomedicine catalytic

Nowadays it is unusual that a person can start a whole branch of science. However, thechemical Tessy Lopez Goerne at the Autonomous Metropolitan University has achievedinnovation in cancer treatment, using nanotechnology.

Working with microscopic particles of substances such as titanium and zirconium filledwith drugs, Lopez has managed to design therapies to attack the cellular structure ofbrain tumors without resorting to surgery or chemotherapy.

His work is in experimental stage, but it is expected that the first treatments begin to appear in the middle of this decade in diseases such as Alzheimer's and Parkinson's.

9. GNOME

The operating systems on the bottom lines of code are only designed to communicatethe various parts of a computer. It is therefore necessary to create a graphical environment (also known as an interface) that the human user can understand.

That was the task that programmers were devoted Mexican Miguel de Icaza and Federico Mena: implemented a free development for family operating systems Linux andUnix.

His invention, originally called GNU Network Object Model Environment (GNOME) and released to the world in 1999 has become one of the most popular free interfaces, making Icaza engineers and celebrities Mena in technology, perhaps the level of LinusTorvalds, the inventor of Linux.

10. Tridilosa 

In 1962, Heberto Castillo, an engineer, looking for a way to replace the heavy concreteslabs formban the roofs of houses and buildings, found that a three-dimensional structureof steel and cement could serve as support for large roofs, weighing up to two thirds less than traditional slab at a much lower cost and better performance as thermal and acoustic insulation.

Castillo's invention has become a solution for buildings that require large roofs in MexicoMedical Center Century XXI.

However, it applied its best efforts in political action, to which he devoted much of his life and for which he was imprisoned in the legendary Black Lecumberri Palace, after the student movement of 1968 and 1971.
