leap year

leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) added to keep the calendar year synchronized with the astronomical year or seasonal year.[1] Because astronomical events and seasons do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting (called intercalating in technical terminology) an additional day or month into the year, the drift can be corrected. A year that is not a leap year is a common year.

In the Gregorian calendar currently in use worldwide (except perhaps the Russian andIranian calendars), there is a leap year every year divisible by four except for years which are both divisible by 100 and not divisible by 400. Therefore, the year 2000 will be a leap year, but the years 1700, 1800, and 1900 were not. The complete list of leap years in the first half of the 21st century is therefore 2000, 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, and 2048.
The extra rule involving centuries is an additional correction to make up for the fact that one extra day every four years is slightly too much correction (). This scheme results in the vernal equinox gradually shifting its date between March 19 and 21, being shifted once every leap year, and then being abruptly shifted in non-leap centuries (see figure above).
In the Gregorian calendar, 97 years out of every 400 are leap years, giving the total number of days in 400 years as

The leap year was introduced in the Julian calendar in 46 BC. However, around 10 BC, it was found that the priests in charge of computing the calendar had been adding leap years every three years instead of the four decreed by Caesar (Vardi 1991, p. 239). As a result of this error, no more leap years were added until 8 AD. Leap years were therefore 45 BC, 42 BC, 39 BC, 36 BC, 33 BC, 30 BC, 27 BC, 24 BC, 21 BC, 18 BC, 15 BC, 12 BC, 9 BC, 8 AD, 12 AD, and every fourth year thereafter (Tøndering), until the Gregorian calendar was introduced (resulting in skipping three out of every four centuries). The UNIX command calincorrectly lists 4 AD as a leap year (Vardi 1991).

Sir John Tenniel

Sir John Tenniel ( 28 February, 1820 – 25 February, 1914) was an English illustrator. 
He drew many topical cartoons and caricatures for Punch in the late 19th century, but is best remembered today for his illustrations in Lewis Carroll's Alice's Adventures in Wonderland and Through the Looking-Glass

In 1865 he illustrated the first edition of Alice's Adventures in Wonderland. The first print run of 2,000 was shelved because Tenniel objected to the print quality; a new edition, released in December of the same year but carrying an 1866 date, was quickly printed and became an instant best-seller, securing Tenniel's lasting fame in the process. His illustrations for both books have taken their place among the most famous literary illustrations ever made. They were used as a reference for the costumes in Disney's Alice in Wonderland, and Tim Burton's Alice in Wonderland
Tenniel's illustrations for the 'Alice' books were engraved onto blocks of wood, to be printed in the woodcut process. The original wood blocks are now in the collection of the Bodleian Library in Oxford. They are not usually on public display, but were exhibited in 2003.

When Tenniel was twenty, in 1840, a fencing accident wit his father forced him to lose the sight in his right eye. A staunchly even tempered man, Tenniel did not react to the pain of the injury, so his father did not even know he had been harmed by his rapier. Undeterred by the partial loss of sight, Tenniel continued on his path as an artist, eventually becoming a beacon in the late nineteenth century world of illustration.
In 1850, Tenniel replaced Richard (Dicky) Doyle at Punch Magazine as a cartoonist, a position he held until 1864 when he replaced his friend John Leech as the principal cartoonist after his death. Steadfast in his routine, Tenniel would continue working at Punch Magazine until his retirement in 1901. During his career at Punch, Tenniel would produce 2,000 cartoons which inspired many famous illustrators, such as Ernest Shepard (who eventually became principal cartoonist at Punch) and Arthur Rackham (who eventually illustrated his own version of Alice’s Adventures in Wonderland). In addition to cartoons, he was also known for book illustrations, such as those in The Gordian Knot by Shirley Brooks (1860), Lalla Rookh by Thomas Moore (1861, considered one of his best works), and The Ingoldsby Legends on which he collaborated with his friend, John Leech and George Cruikshank (1864).
Though Tenniel’s cartoons secured his fame to his contemporaries, it was his illustrations for Lewis Carroll’s Alice’s Adventures in Wonderland that truly made him a household name. Introduced to Carroll in 1864, Tenniel agreed to create forty-two illustrations after reading the manuscript. Carroll, a very particular person who took pride in his own artistic accomplishments, gave Tenniel very specific instructions concerning every aspect of the illustrations. When Tenniel completed the forty-two drafts, Carroll liked only one, the drawing of Humpty Dumpty. The relationship between Tenniel and Carroll was perpetually strained throughout the entirety of the creative process. Tenniel was upset that Carroll would not give him more freedom to execute his creative vision, and Carroll was frustrated by Tenniel’s criticism and pushback about the writing in his manuscript and the printing process. Their identical tendency towards perfectionism would not let them see eye to eye.
One of the distinctive characteristics about Tenniel’s artistic methods was that he would never draw from life. This detail set him far apart from his contemporaries, the Pre-Raphaelites, who believed that studying and drawing from nature was the only way to produce truthful art. Too much the product of academic training, Tenniel worked best when he referred to the techniques and images in his visual memory and drew without observation. This certainly worked in his favor when he argued with Carroll that the creatures in Alice’s Adventures in Wonderland should not look like real animals, but should instead be fanciful creations. Carroll stated that, “Mr. Tenniel is the only artist who has drawn for me who resolutely refused to use a model and declared he no more needed one than I should need a multiplication table to work a mathematical problem.”1
The first printing of Alice’s Adventures in Wonderland was completed in 1865, and Tenniel took issue with the sample print sent to Carroll. Carroll had approved Clarendon Press’ printing for 2,000 copies, however Tenniel deemed it “altogether unacceptable” and insisted that Carroll cancel the print. Carroll was worried that printing would take too long and that it would no longer interest his young friends who “are all grown out of childhood so alarmingly fast.” Despite this worry, as well as the financial loss, Carroll gave the responsibility of printing to Richard Clay, a London printing house who was better equipped than Clarendon to complete the job. Alice’s Adventures in Wonderland was finally printed and issued in November 1865. Between 1865 and 1868, a new edition appeared every year in order to keep up with demand. A sequel was prompted by the success of the first book, and Carroll immediately asked Tenniel to illustrate Through the Looking Glass and What Alice Found There. Though he initially turned him down, Tenniel finally agreed to illustrate Carroll’s second book “at such time as he can find.” Through the Looking Glasswas finally published, after numerous delays, in 1871. The difficult relationship between Tenniel and Carroll did not improve during the creation of the second book. It was such that Tenniel never accepted another illustration project again, and simply continued working on cartoons at Punch. He even went so far to warn Harry Furniss about his upcoming illustration work with Carroll on Sylvie and Bruno. “Lewis Carroll is impossible...I’ll give you a week, old chap; you will never put up with that fellow a day longer.”2
Tenniel lived a relatively solitary life after his wife, Julia Giani, died in 1867, two years into their marriage. He never remarried, so his mother-in-law acted as his housekeeper for twenty-three years until she died and his sister stepped in to care for him. Though flattered by the fame that his illustrations for Carroll’s two books had gained him, Tenniel viewed the work on these classics as a disruption to his routine, and immediately returned to his quiet life at home. In 1893, Tenniel was granted a knighthood for his political cartoons at Punch, as well as for his illustrations in Alice’s Adventures in Wonderland and Through the Looking Glass.
In 1900, when Tenniel was eighty, he retired as the principal cartoonist at Punch. The eyesight in his left eye was failing due to overwork, yet he still continued to paint watercolors until he went completely blind. By the time Tenniel died on February 25, 1914, he was 93 and nearly half a century had passed since Alice’s Adventures in Wonderland was published.

فيروس كورونا: الرئيس الإيراني يستبعد فرض الحجر الصحي على المدن المصابة بالوباء

أعلنت إيران الخميس ارتفاع عدد الوفيات جراء كورونا الجديد إلى 22 حالة، فيما وصل عدد الإصابات بالفيروس لـ141 إصابة مؤكدة.
وبحسب الإحصائيات الرسمية في إيران، فقد تم تسجيل 3 وفيات جديدة بسبب كورونا، الأمر الذي رفع العدد الإجمالي للوفيات بهذا الفيروس إلى 22 حالة، وفقا لما ذكرته وكالة الأنباء الإيرانية "إرنا".
وأضافت الوكالة أنه تم تسجيل 22 حالة إصابة مؤكدة بفيروس كورونا الجديد، الأمر الذي يرفع من العدد الإجمالي للإصابات من 139 إلى 141 إصابة.
وذكرت وزارة الصحة أن معظم الوفيات والإصابات خارج قم كانت بين أشخاص زاروا المدينة المقدسة لدى الشيعة مؤخرا، والتي تشكل بؤرة تفشي كورونا في البلاد.
ودعا المتحدث باسم وزارة الصحة كيانوش جهانبور الإيرانيين إلى تجنب "السفر غير الضروري"، لا سيما إلى المقاطعات التي تضررت بشدة من البلاد مثل جيلان وقم.
وقال الرئيس الإيراني إن طهران ليس لديها خطط فورية لفرض حجر صحي على المدن المتضررة من الفيروس الذي ينتشر بسرعة في جميع أنحاء البلاد.
وتعتبر إيران ثاني أكبر بؤرة للمرض بعد الصين، الأمر الذي دفع بعض الدول الى وقف رحلاتها الجوية إلى إيران وحظر دخول الإيرانيين إلى أراضيها.

Fire TV Stick 4K streaming device with Alexa built in, Ultra HD, Dolby Vision, includes the Alexa Voice Remote







The Amazon Fire TV Stick is the third
 generation of the company's streaming dongle, having been updated to support 4K content.
Like the second gen Fire TV Stick, it boasts an 802.11ac Wi-Fi chip and a 1.7GHz quad-core processor – but buying one still won’t break the bank at under $50. 
You'll also still find voice assistance courtesy of Amazon Alexa, as well as a wealth of content through a variety of different apps, including NetflixAmazon Prime Video, and more. Who needs a smart TV, eh?
While Amazon has rectified some of the issues we had with the previous model, a few small niggling problems still remain that make the experience less than perfect – still, it’s not far off. 
Since the Fire TV Stick 4K was released, Amazon has made a push into televisions with the unveiling of a number of new Fire TV Edition sets, as well as a new Amazon Fire TV Cube, which is an updated version of its Alexa-enabled hands-free streaming media player, adding Dolby Vision and a few other new features to the mix.
