The blue whale is the largest known animal that has ever populated the Earth. These majestic marine mammals dominate the oceans with their 30 meters in length and weighing up to 180 tons. Only his tongue can weigh as much as an elephant, and the heart, like a car.
Blue whales reach these exorbitant dimensions with a diet composed almost exclusively of an animal resembling a tiny shrimp, krill. At ..
The smallest of the family was born, but with all the genetics of his older brothers.
It is a praxinoscope of very small dimensions (just 12 cm in diameter and 12 in height) without therefore the vision of moving images is getting worse, much less and for this it is accompanied by 30 animations in 15 reversible strips , to which you can add if you follow the pattern, all that occur to you if you h..
This beautiful compass has a very special complement and is that below it is hidden an easily removable magnifying glass that is a perfect complement for example in the art of sailing, since in addition to helping us in the course during the voyage, it allows us to make more observations detailed for example of the nautical chart.
It is a reproduction of the compasses that were manufactured in ..
The sundial "Pendulum" is a reproduction of the ones made especially in Germany during the sixteenth century.
It is a horizontal type sundial , which is characterized by being equipped with a pendulum that allows us to place the dial in a perfect position with respect to the horizontal plane. This is an important factor in obtaining more accurate measurements of the solar time.
It was the French mathematician Jean-Baptiste de La Chapelle (1710–1792) who first called the term scaphandre to refer to a kind of flotation suit made with cork that he invented in 1775. The word scuba comes from the Greek: "Skáphos", noun, which can be translated as "boat" or as "basket" and of "Anér, andrós", which is synonymous with "man".Therefore the term scuba could be translated as ..
The Brunton brand is known throughout the world for manufacturing robust compasses of high quality and precision with very special applications. Created and patented in 1894 by David W. Brunton, Canadian geologist and mining engineer, and Guillermo Ainsworth, an expert watchmaker
It is an instrument widely used in geology, also widely used by topographers, foresters and archaeologists.
James Henry Steward (1817-1896) was an expert in optometry. He settled in London in 1852, founding the company that bears his name and became famous worldwide for his highly precise instruments. The company produced a wide range of items for military and civil use, announcing in their catalogs as "manufacturers of specialized instruments in the reconnaissance of the land, the night marches, the dr..
Isaac Newton (1643-1727) was the first to invent the principle of double reflection on which this instrument of navigation is based, however he never published it. Two more researchers, working separately, developed the octant around 1730: John Hadley (1682-1744), an English mathematician, and Thomas Godfrey (1704-1749), a Philadelphia glassmaker
The sextant is an instrument that allows measure..
The use of the astrolabe in the Arab world began in the East (the Mashriq)what we know today as Syria, Lebanon, Jordan and Egypt extending widely by North Africa (the Maghrib), entering almost immediately in Muslim Spain, being already found astrolabes made in Toledo in the XI century.However much earlier in the V century, it is dated a treatise attributed to Ibn al-Sa..
This model differs from the others in that it is not removable and therefore the sand is loaded through a small hole in one of its covers.
It has an advantage and a disadvantage with respect to the other models:

The advantage is that the maneuver of filling the hourglass duri..

This Octant is a replica of the one invented by John Hadley mathematician and English optical mechanic at the beginning of the XVIII century.
Jhon Hadley was born in London in 1682 and he had already demonstrated his enthusiasm and great ability with mathematics since he was a child. In 1717 he founded his first workshop dedicated to the manufacture of scientific instruments entering for that..
Universal Astrolabe Juan de Rojas
In XVI and XVII centuries Louvain (Belgium) was the most important center of astronomers and astrolabe makers. Louvain had it all: Access to learned writings, raw materials and skilled labor. Two styles of universal astrolabes leapt in prominence from this environment, and Genma Frisius (1508-1555) was influential in the development of both. He was directly ..
