Knowledge

• Science is defined as the study of the natural world.
• It is a highly specialised technique of learning about the world or knowing about it.  
• It is a highly powerful way of understanding the world over the last 500 years.
• It is highly responsible for the revolutions that occurred technologically that have happened during this time.  
• However, there are some fields of knowledge and human experience to which scientific methods cannot be applied.  
• Answering merely moral questions or what may be broadly characterised as spiritual questions are examples of these.  
• Science has been unable to examine these areas because they are outside the world of material phenomena, such as matter and energy, and are therefore impossible to witness and quantify.

Abdul Kalam has said "The whole foundation of science is knowledge."

पुस्तकालय विहीन विद्यालय व्यक्ति विहीन समाज है। कहने का तात्पर्य यह है कि जिस प्रकार समाज की संरचना व्यक्तियों से ही सम्भव है, उसी प्रकार से विद्यालय का सुचारु संचालन उसके पुस्तकालय से ही सम्भव है। पाठशाला में विद्यालय की पाठ्यक्रम क्रियाओं को उचित पर्यावरण मिलता है। इस पर्यावरण का स्रोत पुस्तकालय माना जाता है। पुस्तकालय बौद्धिक और सामाजिक क्रियाओं की अभिवृद्धि का स्थान होता है। यही से बालक के अनुभावों का ज्ञान, मानवीय रूप से बदलता है। पुस्ताकालय नवीन ज्ञान का खोज केन्द्र है। वास्तव में पुस्तकालय एक बौद्धिक प्रयोगशाला है, जहाँ हम अपनी बुद्धि के विकास हेतु सत्प्रयास करते हैं। पुस्ताकलय हमारे मस्तिक को स्वच्छ और पोषक भोजन प्रदान करने वाला भोजनालय है।हमारी शैक्षिक दशा में वृद्धि का केन्द्र यही हैं। किसी भी व्यक्ति के लिए यह सम्भव नहीं है कि वह बहुत सारी पुस्तकों को खरीदकर ज्ञानार्जन कर सके, पुस्ताकलय द्वारा वह सभी पुस्ताकों का अध्ययन कर सकता है। जॉन डीवी ने पुस्ताकालय को विद्यालय का हृदय कहा है।

Explanation:

A picnic is a kind of excursion that is arranged with friends and families in the scenic outdoors. Everyone gets together in a place, ideally a park or resort with a lot of open space, and cook meals and eat lunch together, play games, and spend a whole day making merry and memories. In tropical countries like India, families generally plan exciting picnics during winter holidays because, during that time, the weather remains largely pleasant. These picnics though apparently mere get-togethers have immense significance in our life. They allow us to take a break from our busy routine and spend time with our family which is very important for our mental and emotional well-being. In this essay, I shall talk about a family picnic that was probably one of the best days of my life.Picnic Day With My FamilyLast spring our whole family decided to go to a nearby park for a fun outing and a picnic at the same time. The day before the picnic we could no longer hold our excitement. We spent the entire day planning what we will do and what we will eat. Thinking about all the fun we were going to have made my heart flutter. The next day after packing our things we left our home at 8 am. The picnic spot was about 2 hours away from our home. We had packed delicious food prepared by my mother. On our way to the picnic spot, we played “antakshari” in the car. I could not wait to reach the spot.Fun At The Picnic SpotFinally at 10.30 am we reached the picnic spot. It was a beautiful land on the banks of a river. There was a large area of a green field with a lot of bushes and trees scattered here and there. The river and sky met at the horizon. There was a continuous flow of cool breeze blowing from the river to the banks. It was a mesmerizing sight to behold.Me and my siblings, we started playing games with the adults including my mother, father, uncle and aunt. We played gully cricket and hide and seek. Soon the adults became tired so me and my siblings, we started racing across the fields.Finally, we were too tired to play anymore. This was the time for the most amazing part of the picnic, the food. We had brought tasty home-cooked meals from our homes. We unpacked our food and divided it among ourselves. After so many activities my hunger had increased. The food tasted tastier than usual, maybe it was because of the company of the whole family, or maybe it was because I was very hungry. After completing our lunch all of us went for a boat ride. It was my first time riding a boat. At first, I was scared but then slowly I overcame my fear and started enjoying the ride. Then around 5.00 pm, we left for home.The memories I gathered at the family picnic are some moments I will cherish all through my life. The picnic not only provided a break from the everyday mundane life but also made me happy and allowed me to spend some quality time with my family. I hope we can plan more picnics in the future. Picnics are a great way to spend time with our loved ones. We have the opportunity to spend meaningful time with them. What can children say about picnics with their families that they enjoy? We have provided an essay about Picnic with Family for Class 1 students to aid them.A close-knit family is the source of strength for each family member. A family's members are unselfish in their care for one another. They make a person's accomplishments and difficulties smaller by being together through good and bad times. Picnics are a great way to stay connected and close to your friends and family.
