Stephan Hawking---A Brief History of Time (EPUB/PDF)

A landmark volume in science writing by one of the great minds of our time, Stephen Hawking’s book explores such profound questions as: How did the universe begin—and what made its start possible? Does time always flow forward? Is the universe unending—or are there boundaries? Are there other dimensions in space? What will happen when it all ends?

Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and “arrows of time,” of the big bang and a bigger God—where the possibilities are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.

“[Hawking] can explain the complexities of cosmological physics with an engaging combination of clarity and wit. . . . His is a brain of extraordinary power.”—The New York Review of Books

“This book marries a child’s wonder to a genius’s intellect. We journey into Hawking’s universe while marvelling at his mind.”—The Sunday Times (London)

“Masterful.”—The Wall Street Journal

“Charming and lucid . . . [A book of] sunny brilliance.”—The New Yorker

भगवान इंसान की सबसे बड़ी खोज ।

वेदों एवं पुराणों के अनुसार ब्रह्माण्ड की संरचना भगवान ब्रह्मा ने की थी । साथ ही साथ यह भी कहा जाता है की वे विष्णु भगवान की नाभि से निकले कमल से अवतरित हुए थे । ठीक है हम यह मान लेते हैं की यह सच है तो विष्णु ने भगवन कहां से जन्म लिया था । इन सब सवालों के जवाब तो अभी तक कई इंसानों को नहीं पता है । तो आइये चलते हैं इनके जवाब ढूँढ़ने ।

अगर हम किसी भी धर्मों में झाँक के देखें तो हम सही ढंग से यह अनुमान लगा सकते है की हम जिस भी प्राकृतिक घटना को अगर हम समझ नहीं सके तो हमने उसे भगवान का नाम दे दिया । कुछ उदाहरण है जैसे की :-
1 ) सूर्य के प्रकाश का कोई भी कारण हमें नहीं पता था तो हमने उन्हें सूर्य देव बन दिया ।

2 ) इंद्रधनुष को जो की प्रकाश के अपने अलग अलग रंगों में टूटने के कारण बनता है । देवेन्द्र का धनुष बन गया ।

What is Science?

The Fabric of Space and Time

What is Science? is one of the most simplest questions a child curious to know asks.The question itself seems to be a simple one but when one starts explaining it, the answer seems to be a never ending. So what exactly science is what you will came to know today!

The word 'Science' originates from Latin verb Scientia, meaning 'to know'. The Sanskrit word Vijnana(विज्ञान) expresses similar meanings.

Fewer Definitions of Science are :

---

Science alone of all the subjects contains within itself the lesson of the danger of belief in the infallibility of the greatest teachers in the preceeding generation . . .As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.

                                       in The Pleasure of Finding Things Out
                                       as quoted in American Scientist v. 87, p. 462 (1999).

---

The systematic observation of natural events and conditions in order to discover facts about them and to formulate laws and principles based on these facts. 2. the organized body of knowledge that is derived from such observations and that can be verified or tested by further investigation. 3. any specific branch of this general body of knowledge, such as biology, physics, geology, or astronomy.

                                -----------Academic Press Dictionary of Science & Technology

---

Science is an intellectual activity carried on by humans that is designed to discover information about the natural world in which humans live and to discover the ways in which this information can be organized into meaningful patterns. A primary aim of science is to collect facts (data). An ultimate purpose of science is to discern the order that exists between and amongst the various facts.
