As previously stated, Sakharov's passion for physics was passed down to him from his father and he continued to excel in the field. Sakharov studied at home until the eighth grade and eventually graduated with honors. Graduating with honors gave Sakharov the opportunity to advance directly to Moscow University, which housed the best physics department in the country. In his first three years at the University, Sakharov excelled brilliantly. However, after the German invasion of 1941, Sakharov was forced to move to Ashkhabad to continue his studies. Before doing so, Sakharov was supposed to be drafted into the army, but failed a physical fitness test due to a chronic heart condition. Sakharov contributed to the war effort in a different way. “For the duration of the war, Sakharov was assigned to a cartridge factory, where he made substantial contributions to the reliable production of 14.5-millimeter armor-piercing shells by inventing a magnetic device for testing their cores.” This contribution was crucial to maintaining the effectiveness of Soviet anti-tank guns on the front lines. Before the introduction of the Sakharov device, defective shells of the 14.5 millimeter type exploded in the barrels of the weapons. Sakharov's success in this endeavor, as well as his outstanding grades, gave him crucial experience and a worthy resume to begin his
