Analogously to the definition of saw “ordered triples of elements”, we can state a definition that involves four elements.
The non-conservation of the simple reason conical projections necessary to study a new model that is applicable in these representations, a new invariant present in double reasons.
A few times visible phenomenon in which our sun king expels a considerable amount of solar material “coronal mass ejection (CME)”. These phenomena associated with significant changes in magnetic fields can be of different nature.
The video shows one of them in which the mass ejected by gravitational effect returns as “rain”. The proportions of the phenomenon are illustrated by comparing the flare with the size of planet earth.
There are books and books. Some serve mainly to balance a wobbly table, while, others, never cease to fascinate.
The geometry as ancient science is reflected in all aspects surrounding the history of the human. Her knowledge has allowed the development of painting, architecture, interpreting nature …
In particular the segment aureus, the so-called divine proportion or golden rule of geometry, systematically appears in all geometric models to be a basic theme of the training of our current engineers.
By introducing transparent materials have been different parameters that characterize. In “Cycles” have named a shader “Glass” to simulate the behavior of translucent objects where the light changes direction through them.
Has an associated transparency parameter that redirection of light rays passing through the material, is the coefficient of refraction; the software performs calculations to simulate these effects are based on the "Law of Snell".
A beautiful timelapse with images from NASA that reminds us that we have begun to live off planet Earth, in the ISS.
It is the beginning of a long process of expansion in the universe. A first step in the conquest of new spaces in which to live in peace and harmony, between men and nature.
One giant leap for mankind.
NASA often surprise us with their beautiful images of Earth and other celestial bodies. This time it is not an image directly obtained by one of several cameras that orbit our planet, but have made an interesting image compose any number of photographs of different areas at night.
An image can only imagine a world lit by artificial lights night.
With this image, applied as a texture on a sphere in Blender, has made a small animation of planet Earth Evening Dress, in animated GIF format.
Worldmapper is a website that allows you to view data graphically, map shaped Earth, that tell us about our world: The distribution of wealth, its inequalities, risks etc..
The data associated with the different countries are projected on a globe that inflates or deflates their maps to see the impact of the studied data on each of the countries, modifying its appearance.
More than 600 maps covering each one of them a 200 territories, covering 99.95% of the world's population.
Geometry and origami Stella is a book published by Homo Sapiens Ricotti transmitting “happiness” from the world of mathematics. The author takes us to the world of geometry “playing” from bases underlying topological a paper sheet.
A teaching resource certainly of great value that can be entered at different educational levels; allows “touch” mathematics from the realization of the geometric models that express perfection.
Blender is a tool with surprising capabilities. Kelvin Song has created this video to their biology classes using the editing tool, modeling and animation.
A simple animation in which the text is the protagonist, accompanied by a lively band and an elementary render, make this work an artistic reference for scientific and educational publications.
A work that demonstrates how easy it can be effective in many areas of application. Hopefully see more of this level used in the classroom.
From the different solutions to the problem are proposed to obtain circumferences with angular conditions ( passing through a point, are tangent to a circle, forming an angle with a straight), we will analyze this solution using the application of the concepts of power used in the “Fundamental Problem Tangencies” ( PFT ).
The general model search can be the first step of a surveyor training. Later we discuss specific ways this particular problem that could simplify the tracking.
The video that accompanies this page has been produced by “Argonne Labs” and demonstrates the ability to levitate small objects with fluids and sound waves produced by two small speakers with frequencies above 20 KHz (22.000 Hertz)
The two loudspeakers, aligned with high precision, generate some points in space ,called nodes, in which there is no energy transfer; the pressure of the sound waves is able to counteract the force of gravity allowing the drop to remain in suspension. An interesting effect developed by NASA to simulate microgravity and can be used at present for the synthesis of drugs.
