8 Fears


In this challenge the thing we think less is asked more. I guess that's the real 'challenge' in this. Eight Fears. We rarely think of such things, at least I rarely did. Filhal, writing this post after thinking my fears for total two hours in span of 3 days.

1. Loosing dear ones: Very common, Sabko Darr Lagta hai.

2. Dromophobia: The irrational fear that, crossing street will cause bodily harm. Crossing roads is a challenge for me and I googled to know its name :)

3. Nomophobia: Its the fear of loosing mobile: NO MObile Phobia. Actually for me its not in the same meaning; its like, I ll get lost somewhere and ll be unable to contact.

4. Fear of Falling from Height i.e. Acrophobia.

5. I guess I have one different kind of fear: fear from government. I have trust in democracy and constitution but not in the government. Irrespective of ruling party, Central governments did anything to remain in power, from Emergency to Reservations to Love Jihad, there are many things from past and present governments did to retain power.

6. Everyone fears from change and hesitate in taking initiative; me too.

7. Falling in love and loosing it again.

8. Sometimes I loose confidence in front of more intelligent or physically more strong person. Whatever we call it, fear or anything... whatever but its not god.

9 Loves


Every day we add and delete something from us. They may be memories, knowledge, people or anything. So, writing your likes/dislikes at least once in a year is necessary coz it shows your progress, promotion/demotion of healthy thoughts in you and gives idea about your general perception. Filhal, I wrote '10 Days Challenge' approx 4 years back and writing again.



1. Family: Everyone loves their family but when you are far away, you realise it more. I am living away from parents since age of 10 and Everyday I feel like, I want to live remaining years with them. Few Close Relatives included in my "Family'.







2. Friends: In last four years I deleted some, added few new friends and felt more attached to them. I realised the fact that- this is the relation we mutually make on basis of our similarities and likes/dislikes.






3. Reading/Writing: I love reading to know things, to get knowledge, since collecting knowledge about different things and participating in different quizzes is my passion.
                       For me, Writing is something that is necessary like food or air. I know, I am not a good writer/poet but one thing I know for sure- I am learning and continuously improving.




4. Travelling and Photography: My new love. I explored south, now want to visit east and whole north, including small villages with historical significance.
                      Photography is something I am still learning.





5. Drawing and Painting: Like Writing, sometimes I feel painting/drawing as important as food.









6. Mussoorie: Its my dream.





7. Days @Infy: Its the place where I enjoyed the most, realised my dream and found the meaning of friendship.







8. School and School Days: The place where i spent crucial 7 years of my life! Best teacher and many lessons for life.






9. A Girl: Ek Chashme Wali Ladki!


सज़ा – The Punishment

यह किस्सा ईरान का है. खुसरो प्रथम के नाम से ईरान का शासक बनने से बहुत पहले खुसरो एक गुरुकुल में रहता था और उसके गुरु उसे समस्त शास्त्र और विद्या में पारंगत करने के लिए प्रतिबद्ध थे.
एक दिन खुसरो के गुरु ने अकारण ही उसे कठोर शारीरिक दंड दे दिया. कई वर्ष बाद जब खुसरो राजगद्दी पर बैठा तो उसने सबसे पहले अपने गुरु को महल में बुलवाया और पूछा कि उन्होंने सालों पहले किस अपराध के लिए उसे कठोर दंड दिया था.
“आपने मुझे अकारण ही कठोर दंड क्यों दिया? आप भलीभांति जानते थे कि मैंने कोई भी गलती या अपराध नहीं किया था”.
“जब मैंने तुम्हारी बुद्धिमता देखी तब में यह जान गया कि एक-न-एक दिन तुम अपने पिता के साम्राज्य के उत्तराधिकारी अवश्य बनोगे,” गुरु ने कहा.
8361471571_848395c3f9_z“तब मैंने यह निश्चय किया कि तुम्हें इस बात का ज्ञान होना चाहिए कि किसी व्यक्ति के साथ किया गया अन्याय उसके हृदय को आजीवन मथता रहता है. मैं आशा करता हूं कि तुम किसी भी व्यक्ति को बिना किसी कारण के कभी प्रताड़ित नहीं करोगे.”
* * * * *
When he was young, Cosroes (later on Cosroes I) had a master who managed to make him an outstanding student in all the subjects he learned.
One afternoon, for no apparent reason, the master punished him very severely.
Years later, Cosroes succeeded to the throne. One of the first measures he took was to send for his childhood master and demand an explanation for the injustice he had committed.
“Why did you punish me? You know I did not deserve it”
“When I saw your intelligence, I realized right away that you would inherit your father’s throne,” answered the master.
“And so I decided to show you how injustice is capable of marking a man for the rest of his life. I hope that you will never chastise anyone without reason.”

Coelho on Critics





In the past I have received emails from readers who have felt personally insulted when they have read a bad review about one of my books. Firstly, I thank you for your solidarity. Secondly: don’t take the critics too seriously! Just ask: “if you can do better, why don’t you write a book?”
After 20 years of writing, I have come to some conclusions which have helped me a lot in my books. In “The Zahir”, the main character knows already, even before his book is published, what critics are going to say.
It is not up to me to criticize the critics – I am a writer. When I meet one of them (and I meet them very often) they are normally embarrassed. They try to be nice, as if I was insulted. They are normally surprised with my reaction ( “I don’t take your comments as a personal offense”).
Why am I writing this? Because I am convinced that most of you may feel hurt when someone criticizes your work. As I said before, don’t take critics too seriously. Don’t give them the importance they don’t have. They are trying to make a living, and that’s all.
If I did not manage to convince you, please read the comments below:
Do what you feel in your heart to be right, for you’ll be criticized anyway. ~ Anna Eleanor Roosevelt
Critics should find meaningful work ~ John Grisham
To escape criticism “” do nothing, say nothing, be nothing. ~ Elbert Hubbard
It isn’t what they say about you, it’s what they whisper. ~ Errol Flynn
If criticism had any power to harm, the skunk would be extinct by now. ~ Fred Allen
Don’t be afraid of opposition. Remember, a kite rises against, not with, the wind. ~ Hamilton Mabie
There is no defense against criticism except obscurity. ~ Joseph Addison
I have always been very fond of them (drama critics) . . . I think it is so frightfully clever of them to go night after night to the theatre and know so little about it. ~ Noel Coward
All the world’s a stage, and all the clergymen critics. ~ Gregory Nunn
A fly, Sir, may sting a stately horse and make him wince; but one is but an insect, and the other is a horse still. ~ Samuel Johnson
Critics don’t buy records. They get ‘em free. ~ Nat King Cole
Critics search for ages for the wrong word, which, to give them credit, they eventually find. ~ Peter Ustinov
I don’t like to write like God. It is only because you never do it, though, that the critics think you can’t do it ~ Ernest Hemingway (Nobel Prize of Literature)
Critics are like eunuchs in a harem; they know how it’s done, they’ve seen it done every day, but they’re unable to do it themselves.

सवेरे जल्दी उठने के दस फायदे और तरीके

लियो बबौटा ग्वाम में रहते हैं और एक बहुत उपयोगी ब्लॉग ज़ेन हैबिट्स के ब्लौगर हैं। वे लेखक, धावक, और शाकाहारी हैं। उन्होंने हाल में ही एक बेस्ट-सेलिंग पुस्तक ‘The Power of Less’ लिखी है। उनके ब्लॉग पर आप सफलता पाने, रचनात्मकता बढ़ाने, व्यवस्थित होने, प्रेरित होने, क़र्ज़ से निजात पाने, पैसा बचाने, दुबला होने, अच्छा खाने, सहज रहने, बच्चों का लालन-पालन करने, खुश रहने, और अच्छी आदतें विकसित करने के लिए बेहतरीन पोस्ट पढ़ सकते हैं। 
clockहाल में मेरे एक पाठक ने मेरे रोज़ सवेरे 4:30 बजे उठने की आदत, इसके लाभ और उठने के उपायों के बारे में पूछा। उनका सवाल बहुत अच्छा है पर सच कहूँ तो इसके बारे में मैंने कभी गंभीरता से नहीं सोचा।
वैसे, इस आदत के कुछ लाभ तो हैं जो मैं आपको बता सकता हूँ:
पहले मैं आपको यह बता दूँ की यदि आप रात्रिजीवी है और इसी में खुश हैं तो आपको अपनी आदत बदलने की कोई ज़रूरत नहीं है। मेरे लिए रात का उल्लू होने के बाद जल्द उठने वाला जीव बनना बहुत बड़ा परिवर्तन था। इससे मुझे इतने सारे लाभ हुए कि अब मुझसे सवेरे देर से उठा न जाएगा। लाभ ये हैं:
1 – दिन का अभिवादन – सवेरे जल्दी उठने पर आप एक शानदार दिन की शुरुआत होते देख सकते हैं। सवेरे-सवेरे जल्द उठकर प्रार्थना करने और परमपिता को धन्यवाद देने का संस्कार डाल लें। दलाई लामा कहते हैं – “सवेरे उठकर आप यह सोचें, ‘आज के दिन जागकर मैं धन्य हूँ कि मैं जीवित और सुरक्षित हूँ, मेरा जीवन अनमोल है, मैं इसका सही उपयोग करूँगा। अपनी समस्त ऊर्जा को मैं आत्मविकास में लगाऊँगा, अपने ह्रदय को दूसरों के लिए खोलूँगा, सभी जीवों के कल्याण के लिए काम करूँगा, दूसरों के प्रति मन में अच्छे विचार रखूँगा, किसी से नाराज़ नहीं होऊंगा और किसी का बुरा नहीं सोचूंगा, दूसरों का जितना हित कर सकता हूँ उतना हित करूँगा'”।
2 – शानदार शुरुआत – पहले तो मैं देर से उठा करता था और बिस्तर से उठते ही ख़ुद को और बच्चों को तैयार करने की जद्दोजहद में लग जाता था। कैसे तो भी बच्चों को स्कूल में छोड़कर दफ्तर देर से पहुँचता था। मैं काम में पिछड़ रहा था, उनींदा सा रहता था, चिडचिडा हो गया था। हर दिन इसी तरह शुरू होता था। अब, मैंने सवेरे के कामों को व्यवस्थित कर लिया है। बहुत सारे छोटे-छोटे काम मैं 8:00 से पहले ही निपटा लेता हूँ। बच्चे और मैं तब तक तैयार हो जाते हैं और जब दूसरे लोग आपाधापी में लगे होते हैं तब मैं काम में लग जाता हूँ। सवेरे जल्दी उठकर अपने दिन की शुरुआत करने से बेहतर और कोई तरीका नहीं है।
3 – दिन की शांत शुरुआत – बच्चों की चें-पें, खेलकूद का शोर, गाड़ियों के हार्न, टी वी की चिल्लपों – सवेरे यह सब न के बराबर होता है। सुबह के कुछ घंटे शांतिपूर्ण होते हैं। यह मेरा पसंदीदा समय है। इस समय मैं मानसिक शान्ति का अनुभव करता हूँ, स्वयं को समय दे पता हूँ, खुली हवा में साँस लेता हूँ, मनचाहा पढता हूँ, सोचता हूँ।
4 – सूर्योदय का नज़ारा – देर से उठनेवाले लोग हर दिन घटित होनेवाली प्रकृति की आलौकिक प्रतीत होनेवाली बात को नहीं देख पाते – सूर्योदय को। रात काले से गहरे नीले में तब्दील होती है, फ़िर हलके नीले में, और आसमान के एक कोने में दिन की सुगबुगाहट शुरू हो जाती है। प्रकृति अपूर्व रंगों की छटा प्रस्तुत करती है। इस समय दौड़ने की बात ही कुछ और है। दौड़ते हुए मैं दुनिया से कहता हूँ – “कितना शानदार दिन है!” सच में!
5 – नाश्ते का आनंद – सवेरे जल्दी उठकर ही आप नाश्ते का आनंद ले सकते हैं। नाश्ता दिनभर का सबसे ज़रूरी भोजन है। नाश्ते के बिना हमारी देह धीमी आंच पर काम करती है और दोपहर के भोजन तक हम इतने भूखे हो जाते हैं की कुछ भी अटरम-सटरम खा कर पेट टाइट कर लेते हैं, जैसे समोसे, जलेबी, पोहा, पकौडे, आदि। सवेरे अच्छा नाश्ता कर लेने से इनकी ज़रूरत नहीं पड़ती। इसके अलावा, चाय-काफी की चुस्कियां लेते हुए सवेरे अख़बार पढ़ना या दफ्तर में काम की शुरुआत करना कितना सुकूनभरा है!
6 – कसरत करना – यूँ तो आप दिनभर में या शाम को कभी भी कसरत कर सकते हैं पर सवेरे-सवेरे यह करने का फायदा यह है कि आप इसे फ़िर किसी और समय के लिए टाल नहीं सकते। दिन में या शाम को तो अक्सर कई दूसरे ज़रूरी काम आ जाते हैं और कसरत स्थगित करनी पड़ जाती है।
7 – रचनाशीलता होना – सभी इस बात को मानेंगे की सुबह का समय बहुत रचनात्मक ऊर्जा से भरा होता है। सुबह किसी किस्म का व्यवधान नहीं होता और मैं लिखता हूँ, मेल पढता हूँ, ब्लॉगिंग करता हूँ। इस तरह समय की थोड़ी बचत हो जाती है तो मैं शाम को परिवार के साथ वक़्त गुज़र लेता हूँ, जो बहुत ज़रूरी है।
8 – लक्ष्य बनाना – क्या आपने अपने लिए कुछ लक्ष्य निर्धारित किए हैं? नहीं? आपको करना चाहिए! लक्ष्य बनाइये और सुबह जल्दी उठकर उनकी समीक्षा करिए। इस सप्ताह कोई एक काम करने की ठान लें और उसे समय पर पूरा कर लें। लक्ष्य बनाने के बाद हर सुबह उठकर यह तय करें कि आज आप अपने लक्ष्य को पाने की दिशा में कौन से कदम उठाएंगे! और वह कदम आप हर सुबह सबसे पहले उठायें।
9 – काम पर आना-जाना – भयंकर ट्रेफिक में आना-जाना कोई पसंद नहीं करता। दफ्तर/काम के लिए कुछ जल्दी निकल पड़ने से न केवल ट्रेफिक से छुटकारा मिलता है बल्कि काम भी जल्द शुरू हो जाता है। यदि आप कार से जाते हैं तो पेट्रोल बचता है। थोड़ा जल्दी घर से निकल रहें हो तो मोटरसाईकिल चलाने का मज़ा उठा सकते हैं।
10 – लोगों से मिलना-जुलना – सवेरे जल्दी उठने के कारण लोगों से मिलना-जुलना आसान हो जाता है। जल्दी उठें और तय मुलाक़ात के लिए समय पर चल दें। जिस व्यक्ति से आप मिलने जा रहे हैं वह आपको समय पर आया देखकर प्रभावित हो जाएगा। आपको मुलाक़ात के लिए ख़ुद को तैयार करने का समय भी मिल जाएगा।
यह तो थे जल्द उठने के कुछ फायदे। अब जल्द उठने के तरीके बताऊंगा:
* यकायक कोई बड़ा परिवर्तन न करें – यदि आप 8 बजे उठते हैं तो कल सुबह 5 बजे उठने के लिए अलार्म नहीं लगायें। धीमी शुरुआत करें। कुछ दिनों के लिए समय से 15मिनट पहले उठने लगें। एक हफ्ते बाद आधे घंटे (15 मिनट बढाकर) पहले उठने लगें। ऐसा ही तब तक करें जब तक आप तय समय तक न पहुँच जायें।
* थोड़ा जल्दी सोने का प्रयास करें – देर रात तक टी वी देखने या इन्टरनेट पर बैठने के कारण आपको देर से सोने की आदत होगी लेकिन यदि आप सवेरे जल्दी उठने की ठान लें तो यह आदत आपको बदलनी पड़ेगी। अगर आपको जल्द नींद न भी आती हो तो भी समय से कुछ पहले बिस्तर पर लेट जायें। चाहें तो कोई किताब भी पढ़ सकते हैं। अगर आप दिनभर काम करके ख़ुद को थका देते हों तो आपको जल्द ही नींद आ जायेगी।
* अलार्म घड़ी को पलंग से दूर रखें – यदि आप अपनी घड़ी या मोबाइल में अलार्म लगाकर उसे सिरहाने रखते हैं तो सवेरे तय समय पर अलार्म बजने पर आप उसे बंद क़र देते हैं या स्नूज़ कर देते हैं। उसे पलंग से दूर रखने पर आपको उसे बंद करने के लिए उठना ही पड़ेगा। एक बार आप पलंग से उतरे नहीं कि आप अपने पैरों पर होंगे! अब पैरों पर ही बनें रहें और काम में लग जायें।
* अलार्म बंद करते ही बेडरूम से निकल जायें – अपने दिमाग में बिस्तर पर फ़िर से जाने का ख्याल न आने दें। कमरे से बाहर निकल जायें। मेरी आदत है कि मैं उठते ही बाथरूम चला जाता हूँ। बाथरूम से निकलने के बाद ब्रश करते ही दिन शुरू हो जाता है।
* उधेड़बुन में न रहें – यदि आप सोचते रहे कि उठें या न उठें तो आप उठ नहीं पाएंगे। बिस्तर पर जाने का ख्याल मन में आने ही न दें।
* अच्छा कारण चुनें – सुबह-सुबह करने के लिए कोई ज़रूरी काम चुन लें। इससे आपको जल्दी उठने में मदद मिलेगी। मैं सवेरे ब्लॉग पर लिखना पसंद करता हूँ – यह मेरा कारण है। जब यह काम हो जाता है तब मैं आपके कमेंट्स पढ़ना पसंद करता हूँ।
* जल्दी उठने को अपना पारितोषक बनायें – शुरू में यह लग सकता है कि आप जल्दी उठने के चक्कर में ख़ुद को सता रहे हैं। लेकिन यदि आपको इसमें आनंद आने लगा तो आपको यह एक उपहार/पुरस्कार लगने लगेगा। मेरा पारितोषक है गरमागरम कॉफी बनाकर किताब पढ़ना। स्वादिष्ट नाश्ता बनाकर खाना या सूर्योदय देखना या ध्यान करना आपका पारितोषक हो सकता है। कुछ ऐसा ढूंढें जिसमें आपको वास्तविक आनंद मिलता हो और उसे अपनी प्रातः दिनचर्या का अंग बना लें।
* बाकी बचे हुए समय का लाभ उठायें – सिर्फ़ 1-2 घंटा पहले उठकर कम्प्युटर पर ज्यादा काम या ब्लॉगिंग करने में कोई तुक नहीं है। यदि यही आपका लक्ष्य है तो कोई बात नहीं। जल्दी उठकर मिले अतिरिक्त समय का दुरुपयोग न करें। अपने दिन को बेहतर शुरुआत दें। मैं बच्चों का लंच बनाता हूँ, दिन में किए जाने वाले कामों की योजना बनाता हूँ, कसरत/ध्यान करता हूँ, पढता हूँ। सुबह के 7:00 तक तो मैं इतना कर चुका होता हूँ जितना दूसरे कई लोग दिनभर में करते हैं।

Supernova Hypothesis of Origin of Earth

This hypothesis was put forth by Fred Hoyle in 1946. The sun had once a companion star as its former twin, which exploded due to nuclear reactions resulting in transformation of lighter elements into heavier ones.
This explosion in the companion star produced a cloud of incandescent gases and this stage is named by him as the "Supernova stage". This gaseous cloud was retained by the sun's gravitational force and the remainder of the star as the nucleus receded away far off. In the supernova stage, the gaseous cloud contained particles of iron and other terrestrial elements.
These particles aggregated to form the earth and other planets and satellites. As they were within the sun's gravitational field, they revolved round the sun and gradually cooled down to the solid form in which the planets and the satellites exist at present. This hypothesis explains:-
 (i) the great distance between the sun and its planets 
(ii) problem of angular momentum of the planets 
(iii) compositional differences in elements of the sun and the planets. 
However, it fails to account for the cigar shaped arrangements of the planets.
Origin not yet fully known: Of the many hypotheses so far postulated, some had gained acceptance for a time and then were discarded on the advent of new ones which earned followers to meet the same fate.
Notwithstanding the fact that there has been astounding development in the fields of astronomy and astrophysics, the origin of the solar system in general and of the earth, in particular is not as yet definitely known. There seems to be a great deal to know and theorise.
The general consensus among the astronomers is that the earth like other planets and satellites had its birth as a gaseous and hot ball of fire. It cooled down from a primary gaseous state to its present solid form.

Rock Formation

Geological cycle includes many processes acting simultaneously. The most important of these begin with molten magma from within the earth forming into rock, then continue with rocks being broken down into soil, and that soil being converted back into rock.
Rocks are classified according to their place in the geologic cycle. The three major categories are
  • Igneous,
  • Sedimentary and
  • Metamorphic

Types of Rocks and types of rock formations

Igneous Rock: The geologic cycle begins with magma, a molten rock deep inside the earth. This magma cools as it moves upward toward the ground surface, forming igneous rocks.
Classification of Igneous Rock: On the basis texture (size, shape and arrangement of mineral grains in a rock) and mode of occurance, Igneous rock is divided broadly into two types:
Intrusive (also called plutonic rocks): form below the ground surface, where they cool slowly,
Extrusive (also called volcanic rocks) arrive at the ground surface in a molten state, such as through volcanic eruption. This type of igneous rock cool very rapidly.

1. Igneous Rock formation:

Hypabyssal Rock: Hypabyssal rocks are formed when consolidation of magma takes place very close to the earth’s surface in the form of smaller sheet like bodies (known as sills and dykes) that fill cracks inside other rocks.
Some extrusive generally have finer grained, smoother surfaces. Some extrusive materials, such as volcanic ash, bypasses the rock stage and forms directly into sediment

Common Igneous Rocks

Some common igneous rocks include:
Granite: is coarse grained, an intrusive rock. It the most common and familiar igneous rocks. Granite contains primarily orthoclase feldspar and quartz, with some biotite and amphibole. It is mostly light in color with a white or pink tint according to the color of the feldspar.

Engineering properties


Granite have as low as 0.24 per cent. It as an excellent frost resistance. Because of the minerals composition and interlocking of crystals, granite is hard and abrasion resistant. The compressive strength of granite is on average 24,500 psi. it can be concluded that granite can be used to support any load of ordinary structures.
Diorite: is coarse grained, an intrusive rock. It is mainly composed of plagioclase feldspar (more than 50 %) and hornblends. However, in some varieties augite and biotite may be present. It is more abundant than syenites but less abundant than granite.
Diorite has been used for crushed stone for monumental and decorative purposes than for structural purposes.
Syenite: is grained igneous rocks composed essentially of potassium felspare (80-85 %). Biotite and hornblende are commonly present. Quartz is present in small amount. The general properties of syenites is similar to grainite. Because of the rarity of syenite, it is of little commercial use as structural material.
Some other types of igneous rocks are: Rhyolite, Pumice (can be used as pozzolanic materials with cement), Dolerite, Basalt and Gabbro.
Texture: Texture is size, shape and arrangment of mineral grains in a rock. Texture of rock can either of coarse-crystalline or it can be glassy or amorphus. The texture of the rock is governed by the cooling time of the magma. Crystallization is govened by slow cooling, however, glassy texture or amorphous form is the result of rapid cooling.
Types of rock: Holocrystalline, Coarse grained, fine grained, cryptocrystalline and glassy (amorphus)

Dike and sill


Sill: A sill is igneous rock which very in thickness from a few centimeter to several hundred meters. The sill is parallel to the bedding of rock and may be horizontal, inclined or vertical depending upon the strata.
Dike: A dike is vertical wall-like igneous body that cuts the bedding of the rock. The thickness of the dike may vary from a few centimeters to a hundred meter or more.

2. Sedimentary Rocks formation

Sedimentary rock is formed by deposition and consolidation of mineral and organic material and from precipation of minerals from solution. The processes that form sedimentary rock occur at the surface of the earth and within bodies of water. Rock formed from sediments covers 70-80 % of the earth’s land area, and includes common types such as limestone, chalk, sandstone, conglomerate and shale.
Mechanically formed: consisting of materials (gravels, sand, silt and clay) suspended in flowing water. The suspended materials are then deposited and consolidated. The mechanically formed sedimentary rocks are of three types:
  • Rudaceous rocks which is the cementing together of boulders, for example, conglomerate.
  • Arenaceous rocks for example sandstone,
  • Argillaceous rocks which clay rocks for example shale
  • Organically formed: Consisting of accumlated animals and plants remains. They are:
  • Calcarious rocks, lime stone
  • Carbonaceous rocks, coal
  • Chemically formed: this type of rocks is formed by precipitation and accumulation of soluble constituents. These are Carbonate rocks, Limestone, dolomite, Sulphate rocks, Gypsum, Chloride rocks, salt

Consolidation


Consolidation is a process by which soft and loose sediments are converted into hard and firm rocks. Consolidation is of three types:
Compaction and Dehydration: The squeezing out of water from the pores of the sediments and its changing to solid mass by cohesion between the particles and pressure from overlying rock is called compaction and dehydration.
Cementation: Many coarse grained sediments are consolidated by cementation, which is the process of precipitation of some cementing materials, for example, silica, calcium carbonate, iron oxides and clay minerals.
Crystallization: Chemically formed sedimentary rocks such as limestone, dolomites, gypsum etc are consolidated chiefly by the crystallization of their constituents.

Structural Features of sedimentary rocks


  1. Structural features of sedimentary rocks are of great value in determining their origin. The main structures are as follows:
  2. Stratification: The deposition of sediments into layer or beds is called stratification. The thickness of a single bed may vary from a few centimeters to many meters. The stratification is formed due to the following.
  3. Difference in the kinds of materials deposited for example shale and lime stone
  4. Difference in the size of particles deposited for example coarse grained and fine grained stand stone beds
  5. Difference in the color of the material deposited for example light grey and dark grey layers of limestone
  6. Lamination: Thin bedding, less than one centimeter in thickness, are called lamination. It is usually fined grained sedimentary rocks like shales.
  7. Cross-bedding: It is also called current bedding or false bedding. Cross-bedding are the minor bedding or lamination which lie at an angle to the planes of general stratification. This structure is found in shallow water and wind formed deposites.

Different types of sedimentary rocks


Conglomerate: The pebbles and gravels on consolidation and cementation produce a rock known as conglomerate. Gravels are deposited for the most part by water. Water circulating through gravel deposits may precipitate out silica, calcium carbonate, or iron oxides, which act as cements binding the gravels together into conglomerates.
Sandstones: Most sand is a water deposit. In arid regions, widespread sands have been laid down by wind action. Volcanic eruptions, glacial action, mechanical and chemical weathering, and organisms produce sands. The sand particles are deposited and then cemented together by materials like silica, calcite, iron oxide or clay. Sandstones may be siliceous sandstone that is the cementing materials is silica; it may be calcarious sandstone in which the cementing materials is calcium carbonate; ferruginous sandstone and argillaceous sandstone having iron oxide and clay as cementing materials
The thoroughly cemented sandstone with quartz are termed as orthoquartzite.
Argillaceous rocks: variously called mudstone, claystone, and shale (compacted or cemented) are among the most abundant of sedimentary rocks. It is a laminated fine grained sedimentary rock which is mainly composed of clay minerals and some silt-size grains of quartz.
The claystones, because they are characteristically soft and weak are not suited to most construction purposes. The compacted shale lose strength when wet and are subject to plastic deformation. Under load they are subject to failure by flow. The cemented shales have a strength comparable to concrete but have a relatively high elasticity. Clay stones underlying the sites of heavy structures should be test in both wet and dry conditions. Clay stone has a limited use. It serves as a raw materials for the ceramic industry in some places and also used as raw materials for cement production.
Carbonate rocks: The carbonate rocks are chiefly the products of marine or fresh water sedimentation. They are predominantly chemical sediments either formed by metabolic process of organism or precipitated inorgainically. Mineralogically, the carbonate rocks are comparatively simple. There are two main varieties; the limestone composed chiefly of the calcite, and the dolomite composed chiefly of dolomite.
The carbonate rocks, particularly the limestones, have a very wide use in modern industry. The largest single use is as crushed stone. Limestone is one of the leading dimension stones being utilized both for internal and external work. Commercial lime is derived from the burning of limestone.

3. Metamorphic rock formation

When the pre-existing rocks (sedimentary or igneous rock) are subjected to increased temperature, pressure and action of chemically active fluids, metamorphic rocks are formed. During metamorphism re-crystallization of mineral constituent takes place, as a result new minerals and new texture are produced.
The metamorphic processes generally improve the engineering behavior of these rocks by increasing their hardness and strength. Nevertheless, some metamorphic rocks still can be problematic. Some metamorphic rocks are foliated , which means they have oriented grains similar to bedding plains in sedimentary rocks. These foliation is important because the shear strength is less for stresses acting parallel to the foliation.

Types of Metamorphism


Contact metamorphism is the name given to the changes that take place when magma is injected into the surrounding solid rock. The changes that occur are greatest wherever the magma comes into contact with the rock because the temperature are highest at this boundary and decrease with distance from it. Around the igneous rock that forms from the cooling magma is a metamorphosed zone called a contact metamorphism aureole.
Regional metamorphism is the name given to changes in great masses of rock over a wide area. Rock can be metamorphosed simply by being at great depths below the earth’s surface, subjected to high temperatures and the great pressure caused by the immense weight of the rock layers above. Much of the lower continental crust is metamorphic.

Different Metamorphic rocks

Marble: Marbles are metamorphosed carbonate rocks, derived from limestones and dolomites. The color of marble is variable, however, if the rock is pure calcite or dolomite marble it is generally white. Various impurities give rise to various shades. Green, pinks and buffs are common shades.
The principal uses of marble are as cut stone for building and ornamental or decorative use.
Slate: Slate is a dense metamorphic rock, with a strongly developed foliation. It is produced by the metamorphism of shale. The rock cleavage, or splitability is therefore excellent and is the outstanding characteristic of slates. The color of slate varies from iron-tinted reds through various shades of gray and green. The gray shades are due to carbonaceous matter, the greens to chloritic micas. The texture of slates is very fine or dense and foliation is good to perfect.
Slate is used widely in the electrical industries as switchboards.
Phyllite: Phyllite are strongly foliated metamorphic rocks similar to the slates but of slightly coarser texture. Phyllite have shiny luster due the presence of large amount of fine flakes of mica. Phyllite gradually pass into slates which are the first stage in the metaphorphism of shale.
It has little use. It is too soft for crushed stone, and too weak for structural uses.
Schist: Schist are foliated metamorphic rocks of medium to coarse texture. They are the product of the same processes of rock flow and recrystallization that produce slates and phyllite. The color of schist vary according to the mineralogical composition, as does also the perfection of cleavage.
Schist has of little use. Because of the foliation, they are generally weak rocks. Some schists especially rich in muscovite are a source of scrap mica.

origin and evolution of the earth

There are various scientific theories of origin and evolution of the earth
  1. Nebular Hypothesis
  2. Planetesimal Hypothesis
  3. Gaseous Tidal Hypothesis
  4. Binary Star Hypothesis
  5. Gas Dust Cloud Hypothesis

Nabular Hypothesis

  1. German philosopher, Kant and French mathematician, Laplace
  2. Earth, planets and sun originated from Nebula.
  3. Nebula was large cloud of gas and dust. It rotates slowly.
  4. Gradually it cooled and contracted and its speed increased.
  5. A gaseous ring was separated from nebula
  6. Later the ring cooled and took form of a planet
  7. On repetition of the process all other planets came into being
  8. The central region, nebula became sun.

Objections:Interior of the earth

  • Sun should have the greatest angular momentum because of its mass and situated in the center, however, it has only two percent of momentum of the solar system
  • How the hot gaseous material condensed in to rings



Planetesimal Hypothesis

  1. Chamberlin and Moulton proposed the theory in 1904
  2. The sun existed before the formation of planets
  3. A star came close to the sun.
  4. Because of the gravitation pull of the star, small gaseous bodies were separated from the sun
  5. These bodies on cooing became small planet's
  6. During rotation the small planets collided and form planets

Objections:

  • The angular momentum could not be produced by the passing star.
  • The theory failed to explain how the planetesimals had become one planet



Gaseous Tidal Theory

  1. Jeans and Jeffrey proposed the theory in 1925
  2. Large star came near the sun. Due to gravitational pull a gaseous tide was raised on the surface of the sun.
  3. As the star came nearer, the tide increased in size.
  4. Gaseous tide detached when star move away.
  5. The shape of the tide was like spindle.
  6. It broke into pieces-forming nine planets of the solar system

Democracy vs. Republic

Democracy vs. Republic

The key difference between a democracy and a republic lies in the limits placed on government by the law, which has implications for minority rights. Both forms of government tend to use arepresentational system where citizens vote to elect politicians to represent their interests and form the government. However, in a republic, a constitution or charter of rights protects certain inalienable rights that cannot be taken away by the government, even if it has been elected by a majority of voters. In a "pure democracy," the majority is not restrained in this way and can impose its will on the minority.
Most modern nations are democratic republics with a constitution, which can be amended by a popularly elected government.

Comparison chart

Democracy

Republic

Definition
is ruled by the omnipotent majority. In a Democracy, an individual, and any group of individuals composing any minority, have no protection against the unlimited power of the majority. It is a case of Majority-over-Man.A republic is a representative democracy with a written Constitution of basic rights that protect the minority from being completely unrepresented or overridden by the majority.
Constraints on the government
No; the majority can impose its will on the minorityYes; the majority cannot take away certain inalienable rights
Philosophy
All eligible citizens get equal say in decisionsAll eligible citizens get equal say in decisions with protection of unalienable rights to individuals.
Famous Examples
Classical Greece, RomeUnited States Of America
Sovereignty is held by
the whole population (as a group)the people (individuals)
Common confusion in the USA
People commonly confuse direct democracy with representative democracy. The US officially has a representative style, though many have suggested the US is closer to an oligarchy or plutocracy.The US is actually a Republic. It is governed by rule of law. The elected are bound by oath to the written governing limits (ie constitution) yet vote "together" and create laws to address concerns of the represented in a democratic way

JPC PAC Difference

JPC stands for Joint Parliamentary Commission which is appointed by the government in accordance with the opposition to investigate any case of national importance. It is put to use only when the case involves very high profile government officials who are out of the reach of the investigating agencies. It consists of the members of parliament from the ruling side as well as the opposition.

PAC stands for Public Accounts Committee which is an independent body whose head is usually a member of the opposition. The primary function of this body is to assess the financial irregularities in the functioning of the government organisations. The powers of this committee are up to such an extent that it can question even the prime minister,if the need arises

शिक्षा पद्धति का वादा है, वह मुझे बेहतर इंसान बना रही है!

उधारी 

जाते-जाते तुमने,
पीले बादल के कवर वाली किताब में
दबा के जो नया पता दिया था-
उसमें रहती हो क्या?
कुछ सौ रूपये सख्त ज़रूरी हैं,
पुराने इश्क़ के खातिर मिलेंगे?
या हमारा रिश्ता
दो कोढ़ी की उधारी लायक
तक भी न बन सका था?

---*---

अप्रैज़ल (Performance Appraisal )

नस्लभेद बहुत है यहां
गोरी गायों के मंत्री बन गए
काली भैंसे किसी ने न पूछी!
मैं न कहता था,
अप्रैज़ल तुम्हें ही मिलेगा जानेमन
दूध मेरा कोई कितना भी दुहे!

---*---

तुम्हारा चेहरा

छत से दिखता है सूरज
साइकल पे एक बूढ़ा
सड़क पे झड़े पत्ते
मोटे इवनिंग वॉकर्स
और बादलों में तुम्हारा चेहरा.

---*---
शिक्षा पद्धति
बचपन में
किसी को मिले मुझसे कम मार्क्स
किसी को मिले मुझसे ज्यादा.
जिन्हें कम मिले
उन्हें मैंने हीनभावना से देखा,
जिन्हें ज्यादा मिले
मैं उनसे जलने लगा.
शिक्षा पद्धति का वादा है,
वह मुझे बेहतर इंसान बना रही है! 

---*---

चाँद 

रात के शीशे में उजाले का रिफ्लेक्शन
हम भी इसके नीचे, तुम भी तकते इसे
हाय! ये चाँद क्या क्या करता है!!
अपोलो-13 को खूबसूरत न लगा होगा,
जितना इधर से लगता है.


---*---

सुखन 

क़ासिद लौट जाते हैं पते पूछते
न गलियां पता न मेरा पता है.
बैरंग खतों में रंग जो उड़ेले थे

बोसों की सुखन लबों को याद है!

जादू से कोख भर देते हैं

ओट में छुप जाओ की चुम्बन लेना यहां वर्जित है
हाँ, हाँ पेशाब कर लो, सड़क आदमी के बाप की है
शुक्र मनाओ आप भारत में हैं.
उफ़! औरतें ये पर्दा भी नहीं करतीं
ये हैं संस्कार आज के
मादर##, बेन## पश्चिमी संस्कृति का असर है!
हटो की लुंगी पहिन लूँ अब
कच्छे में बहुत क़स्बा नाप लिया.
मेरे क़स्बे के यहां से भी
एक हाइवे निकलना चाहिए.
हमारी औरतें तो कम से कम नित्यक्रिया
आराम से कर सकें!
रहने दो, रेल निकलवा दो
पटरियां काम आएंगी.
गौ-हत्यारी है वो कौम,
ये नहीं सहेगा हिन्दू.
अबे हटा सड़क से वो गाय
मार दो-चार लट्ठ,
किसने साली को यहां छोड़ दिया?
अब क्या इतने भी बुरे दिन हैं कि
रात भर बैठ मानस पढ़ेंगे?
कैसी हिंदी लिखी तुलसी ने,
आधी बात समझ नहीं आती.
सुनो, राम मंदिर वहीं बनेगा
रामजन्म भूमि है वो,
ए. सी. में बैठ हमारे संत यही कह रहे हैं.
हमारे पीर/ संत देवता होते हैं... जादू से कोख भर देते हैं.
बलात्कारी तो एक-दो निकले बस.

टुकड़े

इस शहर में तेरी आत्मा बसती है
तू नुक्कड़, चौराहे हंसती दिखती है.
-*-

हौसलों की बारिश में कोई कमी नहीं
बाप के काँधे हैं, माँ की दुआयें हैं.
-*-

कौन कहता है रौशनी अच्छी लगती है,
तेरे बगैर सहर कोहरे में डूबी लगती है.
-*-

मेरे मुक़द्दर मुझसे बस एक वफ़ा करना,
उस बेवफा को मुकम्मल घर अदा करना.
-*-

मियाँ इस तरह से अजीबो-गरीब शे'र न पढ़ा करो
ग़ालिब, फैज़ की मिलकियत पे वाज़िब हक़ अदा करो.
-*-

मैं वारिस हूँ फैज़ का मुझे लूटोगे क्या,
मेरा हर नगमा तुम्हारी जुबाँ पे बिखर जायेगा.
-*-

तुम्हारे फेंके पत्थरों का शुक्रिया,
मैंने सीढ़िया बनाई औ' आसमां छू लिया.
-*-

प्यास लगे तो तुम मेरा वजूद पी लेना,
माँ ने कहा था पानी साफ़ पीना चाहिए.

"Why do we even try? When the barriers are so high, and the odds are so low? Why don't we just pack it in and go home? It'd be so, so much easier...

It's because in the end, there's no glory in easy. No one remembers easy. They remember the blood, and the bones, and long, agonizing fight to the top. And that, is how you become legendary
" - Grey's Anatomy, Season 11, Episode 14.
