<prompt> Chii chinokonzerwa nokushayikwa kwacho? Tichifunga nezvemubvunzo wapfuura, nyora mashoko akapoteredza mhinduro yacho. Inogona kuva mitsara 1 - 20. Mashoko akapoteredza:  <response>: Kutaura zvisiri izvo kwakajairika kunoti kuomarara uye kuomarara kwezvinhu zvakasimba kunokonzerwa nokudzingwa kwezvinhu zvakafanana zvinenge zviine simba remagetsi. Zvisinei, hunhu uhwu hunobva paPauli exclusion principle. Sezvo maerekitironi ari ma fermion, haakwanise kugara munzvimbo imwecheteyo yema quantum mechanical seimwe maerekitironi. Kana maerekitironi ari muchinhu akavharwa pamwe chete, hapana mamiriro akakwana emagetsi epasi, saka mamwe acho anofanira kunge ari mumamiriro emagetsi akakwirira. Izvi zvinoreva kuti zvinoda simba kuti zvibatanidzwe. Nepo uyu muuyo uchiratidzirwa macroscopically sesimba rakarongwa, unongova bedzi muuyo wokuvapo kweboka rakapera ramamiriro emaerekitironi.
