The Human Cosmos: A Secret History of the Stars

為了解決LED light pollution的問題，作者Marchant, Jo 這樣論述：

An historically unprecedented disconnect between humanity and the heavens has opened. Jo Marchant's book can begin to heal it. For at least 20,000 years, we have led not just an earthly existence but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with t

he stars shaped who we are--our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost. Our relationship to the stars and planets has moved

from one of awe, wonder and superstition to one where technology is king--the cosmos is now explored through data on our screens, not by the naked eye observing the natural world. Indeed, in most countries modern light pollution obscures much of the night sky from view. Jo Marchant's spellbinding pa

rade of the ways different cultures celebrated the majesty and mysteries of the night sky is a journey to the most awe inspiring view you can ever see--looking up on a clear dark night. That experience and the thoughts it has engendered have radically shaped human civilization across millennia. The

cosmos is the source of our greatest creativity in art, in science, in life. To show us how, Jo Marchant takes us to the Hall of the Bulls in the caves at Lascaux in France, and to the summer solstice at a 5,000-year-old tomb at New Grange in England. We discover Chumash cosmology and visit medieva

l monks grappling with the nature of time and Tahitian sailors navigating by the stars. We discover how light reveals the chemical composition of the sun, and we are with Einstein as he works out that space and time are one and the same. A four-billion-year-old meteor inspires a search for extraterr

estrial life. The cosmically liberating, summary revelation is that star-gazing made us human. Jo Marchant is an award-winning science journalist. She has a PhD in genetics and medical microbiology, and an MSc in science communication. She has worked as an editor at New Scientist and Nature, and h

er articles have appeared in The Guardian, Wired, Observer, New Scientist, and Nature. Jo Marchant’s previous book, Cure, hit the New York Times bestseller hardcover nonfiction and science lists and was licensed to 27 countries. She is also author of Decoding the Heavens, which was, like Cure, short

listed for the Royal Society Prize for Science Books.

銥催化劑的合成及其在水相析氫中的應用研究

為了解決LED light pollution的問題，作者陳湘穎 這樣論述：

當前全球對化石燃料的消耗導致化石燃料的枯竭以及二氧化碳和有毒大氣顆粒物的排放，進而導致氣候變遷、環境污染和公共衛生問題。能源問題的最終解決方案是使用太陽能和氫氣。太陽能和水的有效結合產氫滿足了當前和未來能源的巨大需求，使其可再生、可持續，為未來提供無限清潔無污染的能源。本研究使用香豆素 6 和 2-巰基苯並噻唑 (MBT) 及其衍生物配體，並將其與金屬銥結合，合成一系列[Ir(coumarin6)2(X-MBT)] (X = H, 6-Me, 7-Me) 配合物，並通過單晶X射線繞射表徵解析其結構。此外，通過紫外-可見光譜和循環伏安法分析[Ir(coumarin6)2(X-MBT)]配合物的

光學特性和電化學性質。我們並報告[Ir(coumarin6)2(X-MBT)] 配合物在水相中的產氫結果。在燈源設計部分，在500 W氙燈系統的基礎上，我們創新了全新的雙層玻璃系統，（DLGC系統），光源為55 W鹵素燈，比氙氣燈便宜，能耗僅為500 W氙氣燈的十分之一。光源可以從任何地方提供能量，並由於其全透明結構，無需使用聚焦透鏡來增加能量強度，只需將光源放入雙層杯狀結構中即可進行高效的光催化反應。產氫反應中，我們使用DLGC系統針對電子提供者的選擇、電子提供者最適濃度、膦配體的選擇、膦配體與催化劑之最適比例、光敏劑選擇、及噴漆塗染與否等一系列實驗參數進行討論，找出水相產氫的最佳條件。我們

使用DLGC系統作為實驗裝置進行研究，並與氙燈系統的效果進行比較。結果表明，DLGC系統以[Ir(coumarin6)2(6-MBT)]為光催化劑，2.6-雙(二叔丁基膦甲基)吡啶(PNP)為膦配體，1 ,8-二氮雜雙環(5,4,0)十一碳-7-烯(DBU)作為電子供體，具有最高的光催化製氫效率。當反應在90 ˚C、55W鹵素燈和陽光直射下進行時，上述催化劑的最佳轉化頻率（TOF）分別為4399 h-1和212801 h-1。

Falling in Love With Darkness: Overcoming the Fear of Darkness and Discovering Its Qualities of Rest, Relaxation, and Profound P

為了解決LED light pollution的問題，作者Osho 這樣論述：

We have polluted our planet Earth with light. Light pollution - excessive and obtrusive artificial light, with bright neon and LED lights in our cities and in our personal space, continuously illuminated and artificial - has removed something incredibly valuable from our lives, and at the same time

affected our ability to sleep, rest, and relax. 'Falling in Love with Darkness' is Osho's attempt to bring us again in contact with darkness, but here in a spiritual and psychological context. "Why do we desire light?," he asks. "Why do we hanker so much for light? Perhaps we never realize that the

desire for light is a symbol of the fear rooted within us; it is a symbol of fear. We want light so that we can become free of that fear." The mind is afraid in the dark. The fear of darkness is based on the fear of being alone: the fear of being alone comes together with the fear of darkness. Darkn

ess has its own bliss; without falling in love with darkness, you will be deprived of the capacity to love the great truths of life. Next time you find yourself in darkness, take a direct look into it and you will discover that it is not so frightening after all. When darkness surrounds you, become

absorbed in it, become one with it. And you will find that darkness offers you something that light can never give you. All the important mysteries of life are hidden in darkness. These are talks by Osho given at a meditation camp where he introduces people in a direct and practical way to an unders

tanding of meditation as a way to get acquainted with darkness, to re-discover that darkness is peace, relaxation, and stillness, all through the simple method of witnessing. "Meditation means: discovering the one who is beyond all happening and has never been a part of anything."
