Classical description of motion: inertia and momentum Marina de Lourdes Machado1 "Excuse me, this is the Institute of Mechanics," Alice asked, more to make conversation. By poster already knew he was. "Yes, my dear," said the taller of the two and striking. "I am a Mechanical Classic World Classic, and I'm visiting my colleague here, who is a Quantum Mechanic. Whatever your problem, I'm sure one of us canhelp it.'s Just wait until we finish our plays. Both turned to the pool table. The Mechanic Classic took careful aim, considering the tiny portions of all the angles involved. Finally, given the shot at ease. The ball hit and turned in an impressive series of ricochets and eventually collide with the red ball, which landed accurately inside one of the pockets. "There it is," he exclaimed with satisfaction when taking the ball into the hole. "It's how you do it, see? Careful observation and accurate, then action needs. By doing so, you get the result you choose. His companion did not answer, he took his place at the table and made a vague motion with his bat. After their previous experiences, Alice was not surprised to see the ball shoot in all directions at the same time, and there was no place at the table where she could say with certainty that the ball had not been, although he could not tell where the ball was also state. After a break, the player looked inside one of the pockets, reached in and pulled out the red ball. "If you do not mind if I make a remark," said Alice, "it seems that you play very differently." "That's right," replied the mechanic Classic. "I hate when he gives shots that way. I like everything to be done with great care and precision and that all details are planned in advance. However, "he added," I imagine you did not come here to see us play pool, so can you tell us what's you want to know. Robert Gilmore Alice is living a new adventure, now in Country of Quantum.

Fizika točne, uključujući i vaše energije. Mjerenje tih količina može biti izvedena istovremeno bez, međutim, ometa kretanje. Također podrazumijeva se ideja da se kreće čestica opisuje, prije zaustavljanja ili udaranje metu, sukcesije točke koje tvore njegovu putanju. Oba okrenuo na bazen stol. Mehaničar Classic je cilj oprezni, s obzirom na sitne dijelove svih kutova koji su uključeni. Konačno, s obzirom na pucao na gol. Lopta je pogodio i pretvorio se u impresivnom nizu ricochets i na kraju sudaraju s crvenom loptom, što je sletio točno u jedan od džepova. "Tu je," uzviknuo je sa zadovoljstvom prilikom uzimanja loptu u rupu. "To je kako vi to učiniti, vidjet? Pažljivo promatranje i točno, onda treba akcije. Na taj način, možete dobiti rezultat ste izabrali."(Gilmore, 1998, str.40-41) Ove Mehanističkih ideje nose ideju sigurnošću, preciznošću. To je, svemir, kao sat, radi s mehaničkom preciznošću. Za klasične mehanike, položaj imoment čestice definirati njihovo kretanje. Dakle, ove fizičke količine su tako važne za mehaničara klasika. Oni su ono što mi zovemo početni uvjeti ili rubni uvjeti fenomena koje se istražuje. A sada, već možete zamisliti što tako zbunjeno Alice? Što bi mehaničar klasična o tome prije subatomske svijeta? Fotoni, elektroni ... što bi vaše ponašanje? Kao što sam rekao, volim stvari jasne s razlogom se nakon toga učinka, sa svime što je vrlo jasan i predvidiv. U stvari, mnoge stvari koje se događaju ovdje nema smisla za mene, šapnuo u povjerljivim tonom. "Napustio sam klasični svijet samo za spin. Tu je sjajno mjesto gdje se sve događa s mehaničkom preciznošću. Pitanje je dakle učinak predivno predvidljiva, što ga čini sve ima smisla, a vi znate što će se dogoditi. Štoviše, vlakovi su uvijek na vrijeme ", dodao je.(Ibid., str. 42)
