Einstein claimed that matter and energy are interchangeable, so that there is no "absolute" time and space.

爱因斯坦声称物质和能量是可以互相转化的，因此就没有绝对的时间和空间，根本不存在永恒，时间和空间的衡量取决于观测者所在的位置，它们是相对的。

Einstein claimed that matter and energy are interchangeable, so that there is no "absolute" time and space. There are no constants at all, and measurements of time and space depend on the position of the observer. They are relative.

爱因斯坦声称物质和能量是可以互相转化的，因此就没有绝对的时间和空间，根本不存在永恒，时间和空间的衡量取决于观测者所在的位置，它们是相对的。

The various colours significant of various degrees of vitality (white, yellow, crimson, vermilion, cinnabar): their degrees of brilliancy: their magnitudes revealed up to and including the 7th: their positions: the waggoner's star: Walsingham way: the chariot of David: the annular cinctures of Saturn: the condensation of spiral nebulae into suns: the interdependent gyrations of double suns: the independent synchronous discoveries of Galileo, Simon Marius, Piazzi, Le Verrier, Herschel, Galle: the systematisations attempted by Bode and Kepler of cubes of distances and squares of times of revolution: the almost infinite compressibility of hirsute comets and their vast elliptical egressive and reentrant orbits from perihelion to aphelion: the sidereal origin of meteoric stones: the Libyan floods on Mars about the period of the birth of the younger astroscopist: the annual recurrence of meteoric showers about the period of the feast of S.

357显示出不同程度之生命力的缤纷色彩（白、浅黄、深红、朱红、银朱）；诸星之亮度；一直包括到七等星、以等级标志的诸星之大小；诸星的位置；御夫座；沃尔辛厄姆路；大卫的战车；土星光环；螺旋星云凝固后形成有卫星的恒星群；两重大阳相互依存的旋转运动；伽利略、西蒙。马里乌斯、皮亚齐、勒威耶、赫歇耳、加勒等人各自独立地同时所做的发现；波得和开普勒所尝试的距离的立方与回转次数的平方的体系化；多毛的众彗星那几殆无限的被压缩性，以及自近日点至远日点那广漠的远心的重返大气层的椭圆轨道；陨石的恒星之起源；年纪较轻的天体观测者诞生的那个时期火星上所出现的"暗波"现象；每年在圣劳伦斯节前后降落的陨石雨；每月都发生的所谓"新月抱旧月"现象；关于天体对人体的影响的假定；威廉。

Parikh and Wilczek further refined and extended the thought of Keski-Vakkuri and Kraus, the radiation was explained as a tunneling process crossing the barrier of horizon, and in literatures the method is called Parikh-Wilczek tunneling method. In our paper, we further studied the effect of Hawking radiation of the apparent horizon of the dynamical spacetime, the FRW universe, and the thermodynamics of the apparent horizon of the dynamical black hole modes, the Vaidya black hole and the McVittie black hole.

更为重要的是，近年来联系于视界热力学一些新的性质被发现：Einstein方程在视界上可以作为热力学第一定律的形式出现；在Friedmann-Robertson-Walker宇宙表观视界上，时空动力学方程(Friedmann方程)也可以写成一个所谓的统一热力学第一定律的形式；局域定义的FRW宇宙表观视界，也存在着在Kodama矢量观测者看来的Hawking辐射效应。

For a parallel to the lesson of atomic theory...

"与原子理论相对应……在'存在的伟大戏剧'中试图将我们作为观测者和行为者进行调和时，那些如佛陀和老子早就遇到的认识论问题。"

Observers in the path of totality at a solar eclipse see first a gradual covering of the Sun by the lunar silhouette for over an hour, and then a set of 'Baily's beads', the last bits of the bright photosphere shining through valleys aligned at the edge of the Moon.

在一次全食观测中，观测者看见太阳逐渐地被覆盖，最后显示出黑色轮廓的影子，时长超过一小时，之后形似一组珠子状，最后一点明亮的光球层闪烁着排列在月球轮廓的边缘。
