The pages of the SDO (Solar Dynamics Observatory), NASA program to investigate the causes of solar variations, have a repository spectacular images of the sun.
These pages contain a wealth of scientific information on issues concerning solar radiation, with periodic updates its image bank.
One of the first applications that can be found in the Pythagorean theorem, is its use in determining the equation of a circle.
Metric relationship between the two legs of a right triangle are essentially the expression of the concept of Euclidean measure.
The points of a circle are equidistant from the center of the (O).
A circle is the locus of points in a plane equidistant from a fixed point and coplanar another call center in a constant amount called radio.(W)
By projecting a straight line on a plane orthogonal projection, its projection, generally, is smaller than the original measure.
Given a straight (segment bounded by two points) we want to determine its true magnitude and the angle it makes with the planes of projection.
The future plans of NASA we show possible advances in aerospace technology hardly imaginable today.
The Multimedia Gallery NASA can see ideas of what might be future developments of this agency.
An interesting initiative seeks to develop a spacecraft capable of recovering asteroids and lunar orbits take them to where it is possible to study the effect displaced astronauts.
The main projections on two planes straight dihedral (horizontal and vertical planes) possible to determine other new planes orthogonal projections on.
We'll see how generically determine a new projection from two. Later we will consider your application to study the so-called “auxiliary projections”, influencing their usefulness in solving various problems.
Purkinje cells are a type of neuron in the cerebellar cortex in the brain stem.
They have numerous spines on their dendrites that form a highly branched tree.
They are high value anatomical. A cell obtained is presented in the database in the attached image Neuromorpho, and corresponds in particular to a rat treated in Martone laboratoio. For repreentación have used two colors that have established a color ramp that can be associated with anatomical, morphological, the dendritic tree.
The volcanic activity enthusiasts, in particular produced in Canary, have at their disposal an interesting page AVCAN.
On the page we can see, animated form, earthquakes that have occurred in the vicinity of the islands, in a given time range.
After seeing the foundations of Diédrico System, with the projection of a point on two planes orthogonal projection, let's see how you can wean the system of land line as we have two or more points. This system called “Free System” is more flexible than the traditional because Monge, giving prominence to the reference lines and guiding the conceptual model to a more constructive and less spatial geometry.
We have seen in presenting Representation Systems descriptive geometry that is the set of techniques that allows to represent geometric character three dimensional space on a two dimensional surface.
In particular we explore in detail the so-called “System dihedral” based on the prospects ratios appearing in the cylindrical projection on two planes orthogonal projection.
A “Faraday cage” serves as protection for a quadrotor that Vuela between the tesla coils, siendo visually stunning them electric shocks occurring.
El Ingenio flying, junto protection to su, resist them seamless downloads, the discharge can be observed as it receives the cage moves down.
A video that reveals striking aspects of science very striking.
One of the first problems of geometry metric I propose to my students is to start the geometric model analysis while we review the basic transformations studied in earlier.
The problem is posed as a real case study, spiced up with a story that varies as a deeper analysis, and I jokingly call “The Cool River Bridge”, or “problem of the two peoples and the bridge”.
