Science in a Golden Age - Optics: The True Nature of Light
ฝัง

- Playing a vital role in our everyday lives, technologies based on light are in use all around us. From art and science to modern technology, the study of light - and how behaves and interacts with matter has intrigued scientists for over a century.
This year, 2015, marks the 1,000th anniversary of the Kitab al-Manazir (The Book of Optics), a seven-volume treatise written by the Iraqi scientist Ibn al-Haytham - a pioneering thinker who's views have been crucial to our understanding of how the universe came into existence.
Shaping our understanding of vision, optics and light, Ibn al-Haytham interrogated theories of light put forward by the Greeks - men like Plato and Euclid who argued that the way we see objects is by shining light out of our eyes onto them. Ibn al-Haytham argued instead, and correctly, that the way we see is by light entering our eyes from outside either reflecting off objects or directly from luminous bodies like candles or the sun.
His methodology of investigation, in which he combined theory and experiments, were also remarkable for their emphasis on proof and evidence.
In the first episode of Science in the Golden Age, theoretical physicist, Jim al-Khalili, looks at state-of-the-art applications of optics and traces the science of light back to the medieval Islamic world.
Al-Khalili recreates Ibn al-Haytham's famous 'camera obscura' experiment with stunning results and also uncovers the work of Ibn Sahl, a mathematician and physicist associated with the Abbasid court of Baghdad. According to a recently discovered manuscript, he correctly described "Snell's law of refraction" centuries before Dutch astronomer Willebrord Snellius was even born.
We also look at the work of Ibn Mu'adh, who brought together knowledge of optics and geometry in order to estimate the height of the atmosphere.

Great program, hope this will inspire Muslims to get back of being the leaders in science again!
Keep it up Al Jazeera.
They would need 1400 years to catch up to our today's level.
@Akli I am looking. It is the opposite or you are just using sarcasm.
@Akli Same for islamic thievs.
@@George-iv1hi To catch up with Americans or Europeans? I bet it wouldnt take long to catch with the Europeans. They r a hot mess these days. Lol.
@@secrets.295 we did it when there was no Fondation for science then created the very Fondation for modern science.. Back in the days we had almost nothing and we did it within 300 year... what do you think we would do with current situation????
Sad that the large majority of people in the West still believe the enlightment was unique and came straight after the Greek with nothing in between.
Yes, it's a shame that many Westerners either refuse to acknowledge or ignorant of the scientific achievements in the Islamic world that occurred in the Middle Ages.

Here`s what I would say about the West and the Islamic worlds, they both refuse to acknowledge or ignorant of the scientific achievements in the African world that occurred in the ancient world before them. We can see, now that we are in the age of Aquarius all that they have kept and stole from Africa,
Nothing of any importance.
Islam killed science for centuries, in islam belief in muhammed is knowledge.
But now science is successful muhammedans rin to claim it as their own, pathetic losers.
all that they have kept and stole from Africa,
I beg you pardon?

@@worfoz Do u believe in facts?
@@secrets.295 yes, facts and reality
not in lies of some child rapist
@@worfoz why are you in every Ibn al-Haytham video commenting nonsense, do you have nothing better to do? you're really pathetic
@@worfoz You’ve been fed rubbish all your life so naturally truth will heart.
When I was young I saw some of what you see here now in reality, my mom used to tell us to sleep at noon in a room because its too sunny and hot outside and that is not good for health, the room had a window facing the street, so when we turn off the lights and put the curtains on the window, we could see the images of the people walking outside on the inner wall of our room but upside down and moving to the opposite direction, at that time I didn't know anything about science.
Ibn Sahal's law of refraction ❤. Yes please.
What a shame... how many brilliant minds have missed the opportunity to contribute to science because of the ego of primitive men in power.

sooooooooooooooooo trueeeeeeeeee! !!!!!!!!!
Exacly
Over the past 1400 years Muslim intellects have made substantial contributions in the areas of physics, medicine, mathematics, chemistry, astronomy, philosophy and geography. At no time was this more evident than in the Middle Ages, a period commonly referred to as the “Golden Age of Islam”. It produced such luminaries as Jabir ibn Hayyan (considered the father of early chemistry), al-Khwarizmi (one of the fathers of algebra), al-Zahrawi (a father of surgery), al-Razi (father of pediatrics), Ibn Sina (one of the greatest medical scholars in history), Jabir ibn Aflah (promoter of trigonometry in Europe), Ibn Rushd (reviver of Aristotle) and Ibn Khaldun (a father of modern sociology, historiography, demography and economics) to name only a few. Their contributions ultimately helped to usher in the European Renaissance. This influence on Western civilization is recognized in a mural painted in the 1890s on the ceiling of the Library of Congress in Washington D.C. Islam is included along with England, France, America, Greece, Rome and others in a depiction of the “Evolution of Civilization”.
Just, I'm addicted to Jim al-Khalili's lectures and documentaries.
its amazing ,I love your lectures and documentaries
beautiful video sir
i owe you for such a great work you are doing for science and humanity
What a quality content 🙂🙂🙂
Thanks for sharing really informational
Best documentary...
LOVE FROM BANGLADESH
With help of Alllah Islam is torch bearer of Knowledge both day judgement and today but I agree some human can develop on that
Jim khalili is doing great work.
beautifully explained
We( Muslims) are very much aware that our golden age is behind,and that our civilization went to sleep the last few centuries but that's how the world works sometimes,we just relay the torch to the next person to lead humanity,and care for its existence. We all get a turn to be world leaders it just happens in different eras!! Also,when you're not in the lead, your society will start the decay( I.e DETROIT) and that's the normal cycle.
Our civilisation didn't "go to sleep", we were conquered through colonialism which devastated the entire world and then our territories were brutally cut up and deliberately made impoverished and our contributions deliberately obscured. Recognise history!
we didnt go to sleep or obsolete and even the conquer is not what make us fail, but is just only we move away from the teachings of islam and depend on the western world, period
@@muahmmadabubakaar2775 islam teaches evil eye, the notion that we cast some ether from our eyes, to scan and interact.
@@worfoz hmm you are not worth to talk to , because from your reply shows your real portrait ,......
@@muahmmadabubakaar2775 lol, this is how a muslim acts when he is defeated
so immature
try not to die in your rage, best person ever, the world cant exist without you, I know you feel that deep inside
thank you brother jim khalil
Thanks so much for posting,
Tnx to al Jazeera for this.. keep making more and more such documentaries...
Mankinds knowledge is a continuous river of re-discovery 👌

ابو علی حسن بن حسن بن الھیثم بصری. یکم جولائی 965 ع بمطابق 354 ھجری کو بصرہ میں پیدا ہوئے.
اس عظیم سائنسدان کے نام سے ایک ستارے کو بھی موسوم کیا گیا ہے. جس کا نمبر 59239ہے اسے الہازن کہا جاتا ہے.
ابن الہیثم نے طبعیات، طب اور انجینئرنگ میں عظیم الشان کارنامے انجام دیے.
سب سے پہلے اور درست نظریہ بصارت پیش کیا انسانی آنکھ کی تشریح پیش کی جو آج تک کی گئی تحقیق کے مطابق درست ہے. مصر میں دریائے نیل پر بند باندھنے کا منصوبہ پیش کیا مصر کے فاطمی بادشاہ کی دعوت پر جب مصر پہنچے اور دریائے نیل کا مشاہدہ کیا تو اس نتیجے پر پہنچے کہ یہ بند باندھنا ممکن نہیں انکار پر انہیں دس سال تک قید میں ڈال دیا گیا. ابن الہیثم نے اپنی زندگی بچانے کے لیے پاگل پن کا ڈرامہ رچایا جس کی وجہ سے انہیں قتل کرنے کے بجائے قید کی سزا دی گئی. البتہ جس جگہ الہیثم نے بند باندھنے کا منصوبہ پیش کیا تھا آج وہاں مصر کا سب سے بڑا ڈیم اسوان تعمیر کیا گیا ہے. ابن الہیثم نے دنیا کا سب سے پہلا کیمرا ایجاد کیا جسے پن ہول یا سوئی چھید کیمرا کہا جاتا ہے. آج بھی دنیا کا ہر کیمرہ اسی اصول پر کام کرتا ہے جو ابن الہیثم نے بتایا تھا.ابن الہیثم نے اپنے تجربات اور مشاہدات و تحقیق کو کئی کتابوں میں درج کیا ہے. ان کی سب سے مشہور کتاب *کتاب المناظر * ہے جو بصریات کے موضوع پر دنیا کی اولین کتاب ہے.
its simle they learned from us and labelled there names
also we didnt felt to do anything further in science
no one ever learned anything from you
even the nonsense in your quran is stolen, my friend

Layla Beautiful. So, does this mean that Science and Mathematics be void of any metaphorical and linguistic tools of English and other scholarly languages - in order to make people understand the true point behind their works?
In Islam science and Islam r not two entities God says in the Qur'an to do research on his creation God emphasizes us to do research
Great Persian Scientist
@naruto and jojo fans are cringe He was from Buyid dynasty, therefore he was Iranian, by the way Iraq is 150 years old at most, before it there wasn't a land with the name of Iraq. It was always a part of Iran until Ottoman took there and then England took over there and called there Iraq.
@naruto and jojo fans are cringe Yes, you may be an Arab from Iraq, but most Iraqis are not Arabs and have become Arabic speakers. Genetically, they are a mixture of Sami, Iranian and Arabic. If you search TH-cam, you will find videos that prove that many Iraqis have Iranian genes.
As I wrote before, Ibn Haytham lived during the time of Buyid dynasty and not during the time of the Abbasid, they were expelled from Iran in 850 AD, and Haytham was born in 965 AD. Maybe its time you search for truth and knowledge and don't listen to pan Arabs, I hope you are not one of them.

Tell me how and when the dark age started in ur world.
That’s why Americans destroy Baghdad is the fear of the golden age will comeback again, but also to destroy any history related to golden age of Islam
Ironically, the West systematically downplays the achievements of this period, but the East has erased it completely out of memory.
achievements?

Why do you talk about Islamic scientists but not call Newton as christian scientist? Science is science, please don't label it with religion!
And why should it be an issue. People regularly cited Newton as European scientusts, European enlightenment, European renaissance. Whatever. The middle east back then doesnt consider themselves as a continent. They consider themselves as an Islamic superstate. So whenever people mentioned European enlightenment it makes no different than an Islamic Golden Age. There is no contradiction. The world consider the western scientists as a cluster of EUROPEAN SCIENTISTS and they consider middle east scientists as ISLAMIC SCIENTISTS. It shouldnt matter.
not necessarily. They are called muslim scientists because they were encouraged primarily by Islam to seek knowledge.
Because Islam encouraged them to seek knowledge .
And also they were proud of their religion because who wouldnt be when their God , their religion was the one that encouraged these people to read
And please stop with those but but
If you want to call newton christian scientist call him 👍

When the arabs were secular
Not exactly .. they were so religious and spiritual .. at that time existed many Islamic poets and religious scholars that do not exist now ... Even the father of sociology and economic " ibn khaldoun " spoke about the importance of religion for middle east..
@AL KHWARAZMI no harm .. now with the net we can learn
When arabs were rule by islamic sharia , now we are ruled by stupid secular goverments
This is completely overblown nonsense and propaganda.
