The dictum of Democritus and M16

M16: Inside the Eagle Nebula

‘Certainly Democritus said that though the mind thought ill of the senses because in themselves they did not reflect reality, yet it took its evidence from them…(the dictum of Democritus was) that phenomena are a window on the unseen. Through them, if we do not stop there, we can become aware of the nature of the invisible realities.

A man that looks on glasse

On it may stay his eye,

Or if he pleaseth, through it passe

And then the heav’n espie’

(George Herbert)

All things come to pass through conflict

UGC 1810: Wildly Interacting Galaxy from Hubble

‘The counter-thrust brings together, and from tones at variance comes perfect attunement, and all things come to pass through conflict.’

Heraclitus, The Art and Thought of Heraclitus, LXXV

Callas’ stage presence is magnificent.

What is truth?

‘Appearance…constitutes the actuality and the movement of the life of truth. The True is thus the Bacchanalian revel in which no member is not drunk; yet because each member collapses as soon as he drops out, the revel is just as much transparent and simple repose. Judged in the court of this movement, the single shapes of Spirit do not persist any more than determinate thoughts do, but they are as much positive and necessary moments, as they are negative and evanescent.’

星系NGC 5394和NGC 5395的双人慢舞

影像来源及版权:GeminiNSFOIR LabAURA文字:Ryan TannerNASA/USRA

说明:如果你喜欢慢舞,那么你可能会喜欢上这幅图。图中的这支舞,一个转身就需要几亿年。两个星系NGC 5394和NGC 5395在引力的相互作用下围着对方缓慢绕转,一些新的恒星得以形成,像是点缀在其间的火花一般。这张由位于美国夏威夷莫纳克亚山上的双子座北8米望远镜拍摄的图片,是四个波段的照片叠加处理而成。来自氢气的辐射用红色表示,那里是恒星诞生的温床。这些新恒星的诞生将推动着星系的演化。同样可见的还有暗尘带,这里将最终演化成恒星诞生地。如果观察仔细,你将在背景中发现更多的星系,它们中的一些正在上演属于自己的宇宙舞蹈

明日一图预告:open space

‘Let us, then, make a mental picture of our universe: each member shall remain what it is, distinctly apart; yet all is to form, as far as possible, a complete unity so that whatever comes into view, say the outer orb of the heavens, shall bring immediately with it the vision, on the one plane, of the sun and of all the stars with earth and sea and all living things as if exhibited upon a transparent globe.’  Plotinus, The Enneads, V.8.9
