 hello today I'm going to explain: what is a crossbow, a little of his history and the different types. What is a crossbow:  The crossbow is a propelling weapon that is used to shoot arrows or bodoques, consisting of a bow mounted horizontally on a support provided with a mechanism that tightens the rope and another that shoots. Although it is a very old martial instrument, they are still used today, (as for target shooting and hunting). His history:  The crossbow is a weapon that began to be used in the West in a massive way in the 10th century, being the evolution and improvement of the bow and arrow.  It was possible to flex the metal arch with different ways: the first consisted of putting the bow on the ground and tightening the wire with both hands or the foot, until it was locked on a hook. Later various mechanisms (hulks) were mounted on the central rail. The most successful and used was the tensioning by means of a crank tourniquet. Its power became consider...

 Hello, today I am going to explain you: what is archery?, What components is the arch made of?, what types of rope are flexible and resistant?, and his history. Wat is Archery? = Archery is a sport of precision and strength so in principle its practice requires a great capacity for concentration, but also a correct physical preparation. It consists of hitting the closest to the center of the target to obtain the maximum number of points. So far there are seven modalities in archery, which are: 1. Archery on an outdoor target                   2. Indoor archery                   3. Field shooting                   4. Long-distance archery                   5. Bow running                   6. Bow skiing         ...

 It is nearly April and I have decided to teach you one of the sports that I practice: "the archery". I have been practicing this size since I was 5 years old, and it is very funny.  I promise to solve all the questions you have, for example: types of bows, the best arrows, the best places to practice, ... The next entry I am going to explain you: what is the archery, What components is an arc made of, what types of rope are flexible and resistant and their history. And I will saw a video to teach you techniques to hit the center of the objective. Once I have explained what I am going to do, I am going to explain a little about wat is a bow: A bow is a flexible weapon that shoots arrows. A string or loop is attached to the two ends of the bow and when the string is repeatedly stretched, the ends of the bow flex. When the string is released, the potential energy generated by the bending of the bow is transformed into the speed of the arrow. Today, bows and arrows...

Hola chicos, bienvenidos a una nueva entrada de Mapacientíficos.  En el día de hoy os explicaré: qué son, pros y contras, tipos, el hidrógeno y conclusión de las " Energías renovables y no renovables ".  

Hola,  Hace poco hemos empezado a hacer unas clases de impresión con nuestro profesor de informática,      Dani Santos. Os voy a explicar las partes y las funciones de una impresora 3D. Hay dos partes importantes: Extrusor y el Hotend.  Cuatro motores, la barra hierro, (arriba/abajo), eje X(lado a lado) Z Y X (El otro motor impulsa el plástico y el Hotend lo funde) La cama = placa de impresión. Se calienta para que el plástico no se pegue, también tiene que estar bien nivelada. (Placa = es como un ordenador que va dando órdenes a la impresora. Es parecido al Arduino, todos los cables incluidos los dispensadores de calor van hacia el Arduino. Podemos conectar el Arduino, mediante dos entradas : miniUVD y tarjeta micro SD para poner actualizaciones.  Dicho Arduino/ordenador, dispone de dispensadores de calor y todos los cables van hacia el ordenador. Nosotros hemos hecho una mejora para distribuir el aire y que no caigan restos de plástico en el ordenador, pa...

 Hola bienvenidos a mapacientificos hoy os vamos a explicar un poco sobre los números romanos. Estos son los números romanos del uno al 1000: I=1  V=5  X=10 L=50 C=100 D=500 M=1000 Cuando haya un número menor detrás de un número mayor se resta, cuándo es al revés se suma y cuando un número Romano tiene una raya encima es que se multiplica por 1000. Suma   Resta Solo hay cuatro letras que se pueden repetir tres veces la I la X la C y la M MMM=3000 CCC=300 XXX=30 III=3 Un saludo Mapacientificos.

Hola chicos hoy es voy a explicar 10 conectores de inglés, aquí veréis los conectores y sus traducciones, también os explicaré cuando hay que poner un conector en una frase. Éstos van a ser los conectores:           Inglés                             Español           Finally                           Finalmente           And                                Y           Also                               También            Moreover                       Además            Too.     ...
