Vacuum: vacuum truth? Before Evangelista Torricelli(1608-1647), one of the questions that puzzled scientists of the time was how the water only went up a certain height regardless of the method used for this. At that time, an idea which these days may strike us as absurd was regarded as true: Nature abhors a vacuum. The above phrase was sentenced by the scholastic Middle Ages and was inspired by Aristotle(384-322 a. C.), for whom the vacuum would not be likely to exist, as if it existed, the movement did not happen. In Aristotle's conception, the air was responsible for the movement because it drove the bodies. Faced with the impossibility of removing the air, the vacuum would not be likely. However, the idea of non-existence of the vacuum in natural phenomena was not a consensus among those who were devoted to the subject. Another current contrary to Aristotle argued that the existence of the movement should also be empty, otherwise where the body could spend the whole space was occupied? This group was part of Sextus Empiricus(341-270 a. C.), who left his position recorded in his book Against the Logic. Does this stir ends there? It may seem a mess overall. Still others, like Plato, who said that the vacuum would exist only produced by man, not nature. Exist in nature, beyond the atmosphere, a more tenuous ether, and also a small gap between the last particles of bodies. ACTIVITY We say that light is an electromagnetic wave, ie combining electric and magnetic fields. Therefore, the lightpropagates in vacuo. And it is for this reason that the light of the sun and stars, in general, come to Earth, despite the lack of a means for its spread. With respect to the above text, discuss in groups, the existence of the vacuum. Does the interplanetary space is actually the absolute vacuum, ie, the total absence of matter? Are there different types of vacuum?

Vakuum: vakuum istina? Prije Evangelista Torricelli(1608-1647), jedan je od pitanja koja Zbunjen znanstvenici tog vremena bio kako je voda samo otišla do određene visine, bez obzira na metodu korištenu za to. U to vrijeme, ideja koja je ovih dana mogu nas pogađa kao apsurd bio smatran kao istinito: Priroda grozi vakuum.(Bassalo, 1996, str. 97) Gore navedeni izraz je osudio učenim srednjem vijeku, a inspiriran je Aristotel(384-322. C.), za koje je vakuum ne bi bilo vjerojatno da će postojati, kao da je postojao, pokret se nije dogodilo. U Aristotelove koncepcije, zrak je bio odgovoran za kretanje jer odvezli tijela. Suočeni s nemogućnošću uklanjanja zrak, vakuum ne bi bilo vjerojatno. Međutim, ideja o nepostojanju vakuum u prirodnim pojavama nije bilo konsenzusa među onima koji su posvećeni toj temi. Druga struja u suprotnosti s Aristotel je tvrdio da je postojanje pokreta također trebala biti prazna, inače gdje je tijelo moglo provesti cijeli prostor je okupirana? Ova skupina je dio Seksta Empirik(341-270. C.), koji je napustio svoju poziciju snimljene u svojoj knjizi protiv Logike. Da li to stir završava tamo? To se može činiti nered u ukupnom poretku. Drugi pak, poput Platona, koji je rekao da je vakuum bi postojati samo proizveo čovjek, a ne priroda. Postoje u prirodi, izvan atmosfere, više slab eter, ali i mali razmak između posljednje čestice tijela. AKTIVNOST Kažemo da je svjetlost elektromagnetski val, tj. kombiniranjem električnih i magnetskih polja. Stoga, svjetloširi u vakuumu. I to je razlog da je svjetlost sunca i zvijezda, u pravilu, dolaze na Zemlju, unatoč nedostatku sredstava za njezino širenje. S obzirom na gore teksta, razgovarali u skupinama, postojanje vakuuma. Da li međuplanetarni prostor je zapravo apsolutni vakuum, odnosno, ukupna odsutnost materije? Postoje li različite vrste vakuumu?
