Supernova explosion at song dynasty and the principle of constancy of light velocity
宋代超新星爆發(fā)事件與光速不變?cè)?i class="labawb" onClick="playMp3('sound_c_1')">
The method of velocity of light measuring with the cg - iii of light velocity apparatus is improved , the measuring accuracy is increased significantly
摘要對(duì)cg -型光速測(cè)定儀的測(cè)量方法作了改進(jìn)，通過實(shí)際測(cè)量的結(jié)果表明，該實(shí)驗(yàn)方法改進(jìn)后，光速測(cè)量的精度有了很大提高。
He pointed out that , according to the principle of constancy of light velocity , the length of an object in the direction of its movement looked shorter when relative speed of the object was high enough
對(duì)這一論點(diǎn)誰也沒有產(chǎn)生過懷疑，但有一個(gè)人對(duì)此首先發(fā)難，他就是愛因斯坦。本世紀(jì)初1905年，愛因斯坦提出：當(dāng)物體的相對(duì)速度較大時(shí)，這個(gè)物體沿運(yùn)動(dòng)方向的長(zhǎng)度“看上去”會(huì)變短。
