 غوغل إيرث - يحسم جدل النسبة الذهبية وموقع الكعبة على سطح الكرة الأرضية

منذ سنوات يدور جدل كبير بشأن موقع الكعبة على سطح الكرة الأرضية، ويتمحور الجدل فيما إذا كان موقع تلك البقعة المقدسة للمسلمين، يحقق ما يعرف بالنسبة الذهبية Golden Ratio أو النسبة الإلهية، وهي نسبة ترى في جسم الإنسان وفي مختلف النباتات والكائنات الحية، بالإضافة إلى اعتمادها من قبل البشر في صروح تاريخية ولوحات فنية عمرها مئات السنين.
والنسبة الذهبية هي ثابت رياضي اكتشف قبل الميلاد، لكنه لم يحسب بدقة إلى عام 1597 عن طريق عالم الرياضيات الألماني مايكل مايستلن وتبلغ قيمته الدقيقة 1.6180339887
ولتبسيط فكرة النسبة الذهبية، لنتخيل أن لدينا خطا مستقيما بطول ثابت، ونريد قسمه إلى جزء كبير وآخر صغير، فعندما يكون ناتج قسمة طول الجزء الكبير على الصغير مساويا للرقم 1.618، تتحقق النسبة الذهبية بين الجزأين الكبير والصغير.
وهذه النسبة هي التي وجد المعماريون والفنانون والمهندسون منذ القدم أنها تقدم درجة التناسق والجمال الأفضل، فاستخدمت في أهرامات مصر وفي مبنى “البارثينون” الذي شيده الإغريق منذ 2500 عام، وهي موجودة إلى الآن في مبان حديثة مثل مقر البنتاغون.
ولكن قبل الفن والعمران، فإن هذه النسبة الذهبية موجودة في كل تفصيل من جسم الإنسان ومختلف الكائنات الحية الأخرى، لذلك يسميها البعض بالنسبة الإلهية.
فوجه الإنسان المثالي مثلا يزخر بالعديد من الأمثلة على النسبة الذهبية التي أظهرتها قياسات المصممين والفنانين، فالرأس مستطيل الشكل ويحقق خط تمركز العينين فيه النسبة الذهبية، وكذلك النسبة في ساق الإنسان بين جزأيه الكبير والصغير، وذات النسبة تنطبق على جزأي الذراع، والمسافة فوق وتحت الفم.
وفي عصر النهضة، اعتمد الفنانون على النسبة الذهبية في أعمالهم الفنية، ومنها لوحة الموناليزا للرسام الإيطالي الشهير ليوناردو دا فينشي الذي شرح كتابا ألفه الكاهن الإيطالي لوكا باشيولي عن النسبة الذهبية بعنوان De divinaproportione أي “التناسب الإلهي”.
موقع الكعبة
بالعودة إلى موقع الكعبة، فإن مسلمين يقولون إن هناك إعجازا إلهيا في اختيار موقع الكعبة بحيث يحقق النسبة الذهبية أو النسبة الإلهية، في تناسق مع وجود هذه النسبة في الإنسان والمخلوقات الأخرى، فيما يعتبرونه دلالة على وجود خالق واحد للكون.
والتأكد من مطابقة موقع الكعبة المشرفة لهذه النسبة سهل جدا في أيامنا هذه، خاصة مع توفر أدوات قياس دقيقة مثل تلك التي يوفرها برنامج غوغل إيرث. وهو ما يعرضه الفيديو التالي.
يظهر الفيديو قياس المسافة بين الكعبة والقطب الجنوبي وهي 12361.17 كيلومترا، ثم قياس المسافة بين الكعبة والقطب الشمالي وهي 7639.50 كيلومترا. وعند تقسيم الرقم الأول على الثاني تكون النتيجة 1.618 وهي تماما النسبة الذهبية، ويمكن لأي كان تجريب عملية القياس هذه وستكون النتيجة دوما 1.6 التي تشكل النسبة الذهبية.
لكن ماذا عن موقع الكعبة بالنسبة لخطي الشرق والغرب؟ من المستحيل إجراء عملية القياس السابقة في غوغل إيرث، ولابد من خريطة مسطحة لإجراء عملية القياس.
يمكن لأي شخص الحصول على خريطة دقيقة مسطحة للكرة الأرضية، مثل خرائط ناسا، وتطبيق النسبة الذهبية على طول الخريطة وعرضها. ويتم تطبيق النسبة الذهبية من خلال تقسيم طول الخريطة على 1.618 والقيام بنفس العملية بالنسبة لعرض الخريطة.
عند تقسيم الخريطة إلى قسمين بشكل أفقي وفقا للنسبة الذهبية يمر الخط الذي يقسم الخريطة من مكة المكرمة، وعند تقسم الخريطة إلى قسمين بشكل عمودي وفقا للنسبة الذهبية فإن الخط الذي يقسم الخريطة يقاطع الخط السابق في موقع مدينة مكة المكرمة، كما يظهر في الخريطة التالية التي طولها (5400 بيكسل) و عرضها (2700 بيكسل).
وبذلك يكون موقع الكعبة المشرفة، هو الوحيد على الكرة الأرضية التي يحقق النسبة الذهبية طولا وعرضا، وهو ما تظهره القياسات بالأدوات العلمية الحديثة.

Dubai to have hyperloop prototype by 2020


Digital to overtake print in U.S. local advertising by 2018

In its new U.S. Local Advertising Forecast 2017, advertising research and advisory firm BIA/Kelsey projects total local advertising revenues in the U.S. to reach $148.8 billion in 2017, up from $145.2 billion this year, representing a growth rate of 2.4 percent. If political advertising was excluded, the growth rate would be 3.9 percent for 2017. BIA/Kelsey defines local advertising as all advertising platforms that provide access to local audiences for national, regional and local marketers.

Faster growth in online/digital advertising revenues is a major component of the projected increases in the overall local advertising pie. BIA/Kelsey estimates online/digital will increase at 13.5 percent, from $44.2 billion in 2016 to $50.2 billion in 2017. That compares with a decrease of 2.4 percent next year for traditional – print and over-the-air – advertising revenues, going from $101.1 billion in 2016 to $98.6 billion in 2017.

BlockChain BitCoin B$ vs Traditional trading

https://youtu.be/WiRFuHXHBhk

What is Blockchain? It's the Tech that runs Bitcoin. In the finance industry it could save $1.7 Trillion in yearly transaction fees and it could disrupt other industries in similar ways. This "financial explainer video" explains how it works, why it's so safe and all the other cool stuff it might be used for.


Blockchain is a Peer to Peer software technology that protects the integrity of a digital piece of information. It was invented to create the alternative currency Bitcoin but may be used for other cryptocurrencies, online signature services, voting systems and many other applications. In this video we explain how it works and what makes it special.

Everyone uses paper money. When you get a 10 dollar bill you trust that it's not fake. If instead someone sent you an email saying "here's 10 dollars" you probably wouldn’t trust it. But when we "transfer money", use an ATM or pay with a deposit card that's pretty much exactly what we do. We're sending money in a digital message.


To make sure no one's cheating or sending money they don't have, these “messages” go through a few trusted banks that keep a record of everything. They know how much money everyone has and deduct it properly for every transaction.

But this becomes expensive when there’s a million transactions around the world every minute. The Economist estimates that banks charged us more than 1.7 trillion dollars to process these payments in 2014. That’s about 2% of the entire world economy! With blockchain we can save a lot of this cost because it lets us send money just like sending an email.


Instead of sending a lot of payment information through a few servers, blockchain uses thousands of personal computers on the internet. All transactions are copied and cross checked between every computer in a system wide accounting book called the ledger, which becomes very safe at scale.

Blockchain doesn’t just allow us to create safe money online, it lets us protect any piece of digital information. This could be online Identity cards, voter ballots, contracts and many other “legal instruments”, bringing bureaucracy into the 21st century.

Abdulla Al Ghurair Foundation STEM scholarship



They may be among the smartest science pupils in their schools, but their dream of attending a top university is threatened by sky-high fees their parents can’t afford. And so a Dhs4.2 billion education endowment scheme by the Abdulla Al Ghurair Foundation could be a lifeline for these three students and many others like, ensuring they will join the ranks of the UAE’s scientists and engineers.

7DAYS caught up with pupils who have applied for the first of 15,000 scholarships that will be given to young people over the next 10 years.

The aim is to ensure that bright pupils who would struggle to afford the typical Dhs90,000 per year fees can get a degree in science, maths, technology or engineering, skills that will be much sough after in the post-oil era Arab world. Successful candidates will begin studying in September or January.

ISLAM
Islam Atia

NAME: Islam Atia

DEGREE:Mechanical engineering

Egyptian science whiz Islam Alaa Atia, 16, dreams of becoming a mechanical engineer – and studying “day and night” has given him a grade of 97 per cent. But his dad already pays more than Dhs100,000 to send Islam’s siblings to school in Ras Al Khaimah and his chances of making it to college look bleak at present.

“I’m hoping to find a sponsor to cover my study in a high ranking university, such as the American University in Cairo or the American University of Sharjah,” he said. “Studying mechanical engineering is my dream but going to a good university is very expensive to cover.”

Islam’s father, Alaa Fathi Atia, who works for a pharmaceutical firm, said that for parents with several children, the costs quickly add up: “Education in the UAE is very expensive. “We’ve already had to pay for school fees and extra tuition. If a father has other children he has to support, he’s going to need help.”

MUAAZ
Muaaz Farouk

NAME: Muaaz Farouk

DEGREE:Industrial engineering

Muaaz Farouk wants to secure a good job to support his family in Dubai. His dad has paid for the schooling of Muaaz and his four siblings on a salary of just Dhs18,000, and he wants a good engineering degree to make sure he can give something back. The 17-year-old Syrian said: “My dad earns just Dhs18,000 a month and he’s paying for my other siblings.

“There’s no way he can pay all of the bills, cover education and pay mine as well. I come from a family that really values education. My father has a PhD but from a university in Russia. He can’t use that degree here because it’s not much of a use in this part of the world. So, he decided to get just any job that can help him pay for our education. The scholarship would really help, so that when I graduate, I can take care of my family.”

 

RANA 1_2615
Rana Abukather

NAME: Rana Abukather

DEGREE:Chemical engineering

Most parents face high school fees – but for a family with six girls, it means most of their budget goes on schooling. Rana Abukather, 17, from Abu Dhabi, has “always dreamed” of becoming a engineer, but fears she will have to opt for a cheaper degree, like business studies.

She told 7DAYS: “I graduated with an average of 97.2. But if I don’t get the scholarship there is no way I can get this degree. It costs more than Dhs100,000 [per year]. “I’m really passionate about chemical engineering.” Rana hopes to attend American University of Sharjah, which is about Dhs45,000 per semester. Her dad already pays Dhs30,000 per year for two of her sisters to go to school. But another sister has a scholarship to study medicine. Rana said: “If I don’t get a scholarship, I’ll have to study something not too expensive. But I don’t want to do something I’m not passionate about for the rest of my life.”

 

Degrees come at a cost for families in UAE

Parents and prospective students face annual university fees of between Dhs50,000 and Dhs180,000 for a place at well-established universities, depending on the type of degree and prestige of the institution. So it is little surprise that more than 14,000 pupils have applied for funding from the Abdulla Al Ghurair Foundation, set up by the Al Ghurair family last year. Costs vary between degrees, but engineering courses are priced at about Dhs50,000 at Heriot-Watt University. This can rise to more than Dhs100,000 at the American University of Sharjah. NYU Abu Dhabi, which has become one of the country’s most prestigious universities, charges about Dhs180,000 per year. The children of UAE nationals and expats alike can consider studying abroad, where in some cases fees are lower. Annual fees in the UK start around Dhs40,000, although studying medicine can cost Dhs175,000. But in addition to the fees, students living in Dubai and Abu Dhabi face high living costs. NYU Abu Dhabi advises prospective students it can cost Dhs95,000 for room, meals and travel per year.

Help with fees to ‘ease the financial burden’

A growing number of schools are introducing full or partial scholarships as part of efforts to invest in the brightest youngsters and ease the financial burden for parents. King’s School, one of the most expensive in Dubai, announced it will offer six pupils the chance to study, with parents paying half of the Dhs88,000 annual fee for year 10, for example. In May, GEMS said it will provide 3,000 full scholarships in the coming years. School fees are among the largest outgoings for a family, and the cost of educating a child rose by 4.8 per cent this year compared to last, figures from the Dubai Statistics Centre showed in April. Lyn Soppelsa, a director at WhichSchoolAdvisor UAE, said: “With the large numbers of new schools that have opened in Dubai over the past two years – and a further 15 expected to open this September – there does seem to be a trend towards offering more incentives to parents to encourage enrolments at their schools. “If this enables students to attend schools offering a higher quality of education, or allows students with particular talents to be supported, this can only be a good development.”
