A classical Chinese landscape does not stick very close to reality. It leaves enough scope for the viewer to use his imagination. The painting can be looked at from any angle and from any viewpoint. One need not see it through the eyes of the painter. The scroll on which the artist paints has white, blank spaces left after every painting. It gives freedom to the viewer to travel up and down. It captures the essence of the inner life.
A European or Western painting, on the other hand, is realistic. The painter wants you to look at it exactly as he had seen it. From a particular angle. It creates an illusion of delicate realism. The story of Quinten in the 15th century illustrates this point clearly. He entered a painter’s studio slyly and painted a fly on the artist’s blank canvas. The artist mistook it for a real fly and tried to drive it away. That story is representative of Western painting.

विज्ञान और तकनीक की अद्भुत खोजों ने मनुष्य के जीवन में एक क्रांति ला दी है। आज का युग विज्ञान का युग है । कंप्यूटर मनुष्य की इन्हीं अद्भुत खोजों में से एक है जिसने मानव जीवन को लगभग सभी क्षेत्रों में प्रभावित किया है ।
आज के युग को यदि हम कंप्यूटर का युग कहें तो अतिशयोक्ति नहीं होगी । शिक्षा मनोरंजन, चिकित्सा, यातायात, संचार आदि सभी क्षेत्रों में कंप्यूटर ने अपनी उपयोगिता सिद्ध की है । शिक्षा के क्षेत्र में कंप्यूटर अत्यंत उपयोगी सिद्ध हो रहे हैं । विद्यालयों में धीरे-धीरे कंप्यूटर विषय अनिवार्य हो रहा है । छोटे शहरों एवं महानगरों में कंप्यूटर की शिक्षा प्रदान करने वाले स्कूलों, शिक्षण संस्थानों आदि की बढ़ती संख्या कंप्यूटर की लोकप्रियता का साक्षात प्रमाण है ।
कंप्यूटर के माध्यम से पठन-पाठन का स्तर भी अच्छा हुआ है । आजकल अनेक ऐसे विद्यालय खोले जा रहे हैं जहाँ इंटरनेट के माध्यम से व्यक्ति घर बैठे ज्ञान प्राप्त कर सकता है । प्रबंधन, कानून व रिसर्च में संलग्न विद्यार्थियों के लिए कंप्यूटर एक वरदान सिद्ध हो रहा है । पुस्तकों के प्रकाशन में भी कंप्यूटरों की अनिवार्य भूमिका हो गई है ।
कार्यालयों में कंप्यूटर के माध्यम से कार्य करना अत्यंत सहज एवं सरल हो गया है। अब कार्यालय संबंधी सभी महत्वपूर्ण आंकडों व तथ्यों को ‘फाइल’ में सुरक्षित रखा जाता है जिससे समय की काफी बचत होती है । अनेक कार्य जिनमें कई व्यक्तियों की आवश्यकता होती थी अब वही कार्य एक कंप्यूटर के माध्यम से बहुत कम समय में ही संपन्न हो जाता है ।
यही कारण है कि अब प्रत्येक सरकारी तथा गैर-सरकारी कार्यालयों में कंप्यूटर का उपयोग अनिवार्य हो गया है । सभी व्यापारिक सूचनाएँ इसमें दर्ज होती हैं जिससे व्यापार करना सरल हो गया है ।
कंप्यूटर के द्वारा संचार के क्षेत्र में एक क्रांति सी आ गई है । ‘ई-मेल’ के माध्यम से हजारों मील बैठे अपने संबंधी अथवा मित्र से लोग बहुत ही कम खर्च तथा समय से अपने संदेश भेज सकते हैं तथा ग्रहण कर सकते हैं । ‘इंटरनेट’ के माध्यम से मनुष्य हर प्रकार की जानकारी का आदान-प्रदान विश्व के किसी भी कोने से करने में सक्षम है । वास्तविक रूप में इंटरनेट का विस्तार असीमित है ।
अत: इसे हम एक विशिष्ट दुनिया के रूप में देख सकते हैं । यह न केवल सूचनाओं के आदान-प्रदान को संभव बनाता है अपितु व्यक्ति को उसके निजी समय या अवकाश के अनुसार किसी भी नवीनतम जानकारी को हासिल करने का स्वर्णिम अवसर प्रदान करता है ।
यातायात के क्षेत्र में भी कंप्यूटर की विशेष उपयोगिता है । हवाई मार्गों का निर्धारण एवं नियंत्रण, महानगरों की ‘रेड लाइट सिग्नल’ प्रणाली आदि कंप्यूटर की ही देन है । इसके अतिरिक्त अंतरिक्ष अनुसंधान, मौसम संबंधी जानकारी, मुद्रण आदि में कंप्यूटर का विशेष योगदान है ।
इस प्रकार हम देखते हैं कि आधुनिक युग में कंप्यूटर मनुष्य के जीवन के हर क्षेत्र से प्रत्यक्ष या परोक्ष रूप से जुड़ा हुआ है । विज्ञान के इस अद्भुत उपहार को नकराना संभव नहीं है । यह आज की आवश्यकता दै । प्रारंभ में अवश्य ही यह एक विशिष्ट जनसमूह तक सीमित था परंतु सरकार के सकारात्मक रुख के कारण यह धीरे-धीरे विस्तार ले रहा है ।
परिणामस्वरूप यह हजारों मध्यवर्गीय लोगों की आवश्यकता बन गया है । हमारे देश में जहाँ बेरोजगारी व आर्थिक संकट के घने बादल हैं, ऐसे वातावरण में निसंदेह कंप्यूटर का विस्तार समय लेगा । परंतु जिस प्रकार इसकी आवश्यकता वढ़ रही है अथवा जिस तीव्रगति से कंप्यूटरीकरण हो रहा है उसे देखते हुए यह अनुमान लगाया जा सकता है कि बहुत शीघ्र ही यह दूरदर्शन की भाँति सभी घरों में अपनी जगह बना लेगा ।

Suppose the numerator of the fraction be x
Denominator of the fraction be y
{tex}\therefore{/tex} the fraction is {tex}\frac{x}{y}{/tex}
According to the question,
The sum of the numerator and denominator of the fraction is 12.
{tex}\Rightarrow x + y = 12{/tex}
{tex}\Rightarrow{/tex} {tex}x + y - 12 = 0{/tex}
If the denominator is increased by 3, the fraction becomes {tex}\frac{1}{2}{/tex}.
{tex}\Rightarrow \frac{x}{{y + 3}} = \frac{1}{2}{/tex}
{tex}\Rightarrow{/tex} {tex}2x = (y + 3){/tex}
{tex}\Rightarrow{/tex} {tex}2x - y - 3 = 0{/tex}
So, we have two equations
{tex}x + y - 12 = 0{/tex}
{tex}2x - y - 3 = 0{/tex}
Here x and y are unknowns.
We have to solve the above equations for x and y.
By using cross-multiplication,
{tex}\Rightarrow \frac{x}{{(1) \times ( - 3) - ( - 1) \times - 12}}{/tex} {tex} = \frac{{ - y}}{{1 \times ( - 3) - 2 \times - 12}}{/tex} {tex}= \frac{1}{{1 \times ( - 1) - 2 \times (1)}}{/tex}
{tex}\Rightarrow \frac{x}{{ - 3 - 12}}{/tex} {tex}= \frac{{ - y}}{{ - 3 + 24}} = \frac{1}{{ - 1 - 2}}{/tex}
{tex}\Rightarrow \frac{x}{{ - 15}} = \frac{{ - y}}{{21}} = \frac{1}{{ - 3}}{/tex}
{tex}\Rightarrow \frac{x}{{15}} = \frac{y}{{21}} = \frac{1}{3}{/tex}
{tex}\Rightarrow x = \frac{{15}}{3},\;y = \frac{{21}}{3}{/tex}
{tex}\Rightarrow{/tex} {tex}x = 5, y = 7{/tex}
The fraction is {tex}\frac{5}{7}{/tex}

There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.

Beginning 135,000 years ago, tropical Africa experienced megadroughts which drove humans from the land and towards the sea shores, and forced them to cross over to other continents. ... Fossils of early Homo sapiens were found in Qafzeh and Es-Skhul Caves in Israel and have been dated 80,000 to 100,000 years ago.
