“... classical Arabic, being the language of the Qur'an, has not changed at all in fourteen centuries, making the writings of the early Islamic scholars as accessible today as they were then.”

“For me, I think the greatest achievements of science is to allow humanity to realize that our world is comprehensible. Through science, rational thinking, we can understand how the universe works.”
― Jim Al-Khalili

“The difference between my beliefs and having a religious faith is that I am prepared to change my views in light of new evidence, but someone of a religious faith will just stick their fingers in the ears and say: 'I'm not listening, there's nothing you can say that will make me change my mind.”

“Arabic science throughout its golden age was inextricably linked to religion; indeed, it was driven by the need of early scholars to interpret the Qur'an.”

“By the time of the arrival of Islam in the early seventeenth century CE, what we now call the Middle East was divided between the Persian and Byzantine empires. But with the spread of this new religion from Arabia, a powerful empire emerged, and with it a flourishing civilization and a glorious golden age.

Given how far back it stretches in time, the history of the region -- and even of Iraq itself -- is too big a canvas for me to paint. Instead, what I hope to do in this book is take on the nonetheless ambitious task of sharing with you a remarkable story; one of an age in which great geniuses pushed the frontiers of knowledge to such an extent that their work shaped civilizations to this day.”

“It is a fact of life that oversimplified accounts of the development of science are often necessary in its teaching. Most scientific progress is a messy, complex and slow process; only with the hindsight of an overall understanding of a phenomenon can a story be told pedagogically rather than chronologically. This necessitates the distilling of certain events and personalities from the melee: those who are deemed to have made the most important contributions. It is inevitable therefore that the many smaller or less important advances scattered randomly across hundreds of years of scientific history tend to be swept up like autumn leaves into neat piles, on top of which sit larger-than-life personalities credited with taking a discipline forward in a single jump. Sometimes this is perfectly valid, and one cannot deny the genius of an Aristotle, a Newton, a Darwin or an Einstein. But it often leaves behind forgotten geniuses and unsung heroes.”

“The trustworthiness of science comes not from certainty, but from its very openness about its uncertainty, always calling into question what we currently understand and being prepared to replace that knowledge with a deeper understanding if something better comes along. In other walks of life, this attitude might be regarded as fickle. But not in science. Scientific progress depends on scientists' unwavering commitment to the qualities of honesty and doubt.”

“I shall mention in passing just one example of a gift from the Arabs that I for one am rather grateful for: coffee -- especially as it was originally banned in Europe as a 'Muslim drink.”

“Many historians regard him [Offa] as the most powerful Anglo-Saxon king before Alfred the Great. In the 780s he extended his power over most of Southern England. One of the most remarkable extantfrom King Offa's reign is a gold coin that is kept in the British Museum. On one side, it carries the inscription Offa Rex (Offa the King). But, turn it over and you are in for a surprise, for in badly copied Arabic are the words La Illaha Illa Allah ('There is no god but Allah alone'). This coin is a copy of an Abbasid dinarfrom the reign of Al-Mansur, dating to 773, and was most probably used by Anglo-Saxon traders. It would have been known even in Anglo-Saxon England that Islamic gold dinars were the most important coinage in the world at that time and Offa's coin looked enough like the original that it would have been readily accepted abroad.”

“In fact, for a period stretching over seven hundred years, the international language of science was Arabic. For this was the language of the Qur'an, the holy book of Islam, and thus the official language of the vast Islamic Empire that, by the early eighth century CE, stretched from India to Spain.”

“I am a cuddly atheist... I am against creationism being taught in schools because there is empirical evidence that it is a silly notion... I am passionately concerned about the rise in pseudo-science; in beliefs in alternative medicine; in creationism. The idea that somehow it is based on logic, on rational arguments, but it's not. It doesn't stand up to empirical evidence.

In the same way in medicine, alternative medicines like homeopathy or new age therapies – reiki healing – a lot of people buy into it and it grates against my rationalist view of the world. There is no evidence for it. It is deceitful. It is insidious. I feel passionately about living in a society with a rationalist view of the world.

I will be vocal on issues where religion impacts on people's lives in a way that I don't agree with – if, for instance, in faith schools some of the teaching of religion suggests the children might have homophobic views or views that are intolerant towards other belief systems...

I am totally against, for example, bishops in the House of Lords. Why should someone of a particular religious faith have some preferential treatment over anyone else? This notion that the Church of England is the official religion of the country is utterly outmoded now.”

“Perhaps death represents the severing of the living organism's connection with the orderly quantum realm, leaving it powerless to resist the randomizing forces of thermodynamics.”

“For the early scholars of Islam, there would have been no conflict between religion and science. The early thinkers were quite clear abou their mission: the Qur'an required them to study alsamawat wal'arth (the skies and the earth) to find proof of their faith. The prophet himself had besought this discipline to seek knowledge 'from the cradle to the grave', no matter how far that search took them, for 'he who travels in search of knowledge, travels along Allah's path to paradise”

“It is not surprising that Ibn Sina is a national icon in Iran today, and one can find countless schools and hospitals named after him in many countries around the world. Indeed, his legacy stretches even further, for there is an 'Avicenna' crater on the moon, and in 1980 every member country of Unesco celebrated the thousand-year anniversary of Ibn Sina's birth. As a philosopher he is referred to as the Aristotle of Islam; as a physician he is known as the Galen of Islam.”

“His (Islamic astronomer al-Farghani) legacy also endures through the Italian writer and poet Dante (1265-1321), who derived most of the astronomical knowledge he included in his DIVINE COMEDY from the writings of al-Farghani (whom he referred to by his Latin name, Alfraganus).”

“One cannot, therefore, understand Arabic science without considering the extent to which Islam influenced scientific and philosophical thought. Arabic science was, throughout its golden age, inextricably linked to religion. Clearly, the scientific revolution of the Abbasids would not have taken place if it were not for Islam, incontrast to the spread of Christianity over the preceding centuries, which had nothink like the same effect in stimulation and encouraging original scientific thinking.”

“Two of the most famous Baghdadi scholars, the philosopher Al-Kindi and the mathematician Al-Khawarizmi, were certainly the most influential in transmitting Hindu numerals to the Muslim world. Both wrote books on the subject during al-Ma'mun's reign, and it was their work that was translated into Latin and transmitted to the West, thus introducing Europeans to the decimal system, which was known in the Middle Ages only as Arabic numerals. But it would be many centuries before it was widely accepted in Europe. One reason for this was sociological: decimal numbers were considered for a long time as symbols of the evil Muslim foe.”

“for we have been deprived of all the people of knowledge save for a group, small in number, with many troubles, whose concern in life is to snatch the opportunity, when time is asleep, to devote themselves meanwhile to the investigation and perfection of a science; for the majority of people who imitate philosophers confuse the true with the false, and they do nothing but deceive and pretend knowledge, and they do not use what they know of the sciences except for base and material purposes; and if they see a certain person seeking for the right and preferring the truth, doing his best to refute the false and untrue and leaving aside hypocrisy and deceit, they make a fool of him and mock him.”

“By thinking about what we don't yet know, we can think about how we can best find out. It is the many questions we have asked over the course of our human history that have given us an ever-more-accurate picture of the world we know and love.”

“Let me first make two important assumptions, which I will discuss in more detail later on, but will now just say that they are both supported strongly by observational evidence: (1) that the laws of physics are the same everywhere in our universe, and (2) that space looks the same in all directions (the same density and distribution of galaxies).”

“When it comes to the meaning of space and time the difficulty we have is not surprising, for we are ourselves imprisoned within them, and it is hard to free our minds from their confines and ‘see’ reality from the outside.”

“When it comes to looking for new ideas in physics, there are, very broadly, two kinds of researchers. Imagine you’re walking home on a dark, moonless night when you realise that there’s a hole in your coat pocket through which your keys must have fallen at some point along your route. You know they have to be somewhere on the ground along the stretch of pavement you’ve just walked, so you retrace your steps. But do you only search the patches bathed in light beneath lampposts? After all, while these areas cover only a fraction of the pavement, at least you will see your keys if they are there. Or do you grope around in the dark stretches in between the pools of lamplight? Your keys may be more likely to be here, but”

equations or in surprising experimental results, but in the deep
underlying principles that govern the way the world is.”
