Lesson— 3
A Curious Mind
COMPLETE CHAPTER SUMMARY
The chapter "A Curious Mind" is written in the form of a play featuring three children: Nikita, Orgo, and Meera. The story begins with Orgo asking Nikita why the sky changes its color during sunset. Nikita gets annoyed because she is busy painting and does not know the reason. Their cousin Meera explains that Orgo's questioning nature is a sign of a curious mind, which is essential for scientific discoveries.
To inspire them, Meera shares the life story of India's great physicist, Sir C.V. Raman. While on a sea voyage in 1921, Raman's curiosity about why the sea looks blue led to the groundbreaking discovery of the scattering of light, known as the Raman Effect. For this, he was awarded the Nobel Prize in Physics in 1930 and India's highest civilian award, the Bharat Ratna, in 1954. The lesson teaches students the value of being inquisitive, respecting others' time, and celebrating National Science Day on February 28 to honor scientific progress.
অধ্যায় সাৰাংশ (Chapter Summary in Assamese)
"A Curious Mind" (এটা কৌতুহলী মন) নামৰ এই পাঠটি এটি নাটকৰ ৰূপত লিখা হৈছে, য’ত নিকিতা (Nikita), অৰ্গ (Orgo) আৰু মীৰা (Meera) নামৰ তিনিটা শিশুৰ কথোপকথন ডাঙি ধৰা হৈছে।
নাটকখনিৰ আৰম্ভণিতে দেখা যায় যে অৰ্গই তাৰ বায়েক নিকিতাক সূৰ্যাস্তৰ ছবি এখন আঁকি থকা অৱস্থাত আকাশৰ ৰং কিয় সলনি হৈ থাকে বুলি এটা প্ৰশ্ন সোধে। নিকিতাই নিজে সেই উত্তৰটো নজনাৰ বাবে আৰু ছবি অঁকাত ব্যস্ত থকাৰ বাবে অৰ্গৰ ওপৰত খং কৰে আৰু তাক আমনি নকৰিবলৈ কয়। এনেতে তেওঁলোকৰ সম্পৰ্কীয় বায়েক মীৰা কোঠালৈ আহে আৰু অৰ্গক বুজাই কয় যে প্ৰশ্ন সোধা বা কৌতুহলী হোৱাটো এটা অতি ভাল গুণ। এই কৌতুহলেই হৈছে পৃথিৱীৰ বহু ডাঙৰ ডাঙৰ আৱিষ্কাৰৰ মূল কাৰণ।
অৰ্গ আৰু নিকিতাক অনুপ্ৰাণিত কৰিবলৈ মীৰাই ভাৰতৰ এজন মহান বিজ্ঞানী ছাৰ চন্দ্ৰশেখৰ ভেংকট ৰমন (C.V. Raman)-ৰ জীৱনৰ এটা গুৰুত্বপূৰ্ণ ঘটনাৰ কথা উল্লেখ কৰে। ১৯২১ চনত যেতিয়া ডেকা ৰমনে জাহাজৰে এক সাগৰীয় যাত্ৰা কৰি আছিল, তেতিয়া তেওঁৰ মনত এটা কৌতুহলী প্ৰশ্ন উদয় হৈছিল— "সাগৰৰ পানীভাগ কিয় নীলা দেখা যায়?" এই এটা সাধাৰণ প্ৰশ্নৰ উত্তৰ বিচাৰিয়েই তেওঁ পোহৰৰ বিক্ষেপণ (scattering of light) সম্পৰ্কে এক যুগান্তকাৰী আৱিষ্কাৰ কৰে, যাক পিছলৈ 'ৰমন প্ৰভাৱ' (Raman Effect) বুলি জনা যায়।
এই মহান আৱিষ্কাৰৰ বাবে তেওঁক ১৯৩০ চনত পদাৰ্থ বিজ্ঞানৰ নোবেল বঁটা প্ৰদান কৰা হয় আৰু ১৯৫৪ চনত ভাৰত চৰকাৰে তেওঁক দেশৰ সৰ্বোচ্চ অসামৰিক সন্মান 'ভাৰত ৰত্ন'ৰে বিভূষিত কৰে। এই আৱিষ্কাৰক স্মৰণ কৰিয়েই প্ৰতি বছৰে ২৮ ফেব্ৰুৱাৰী দিনটো সমগ্ৰ দেশতে 'ৰাষ্ট্ৰীয় বিজ্ঞান দিৱস' (National Science Day) হিচাপে পালন কৰা হয়।
শেষত, মীৰাই দুয়োকে বুজাই দিয়ে যে আমি সদায় নতুন কথা জানিবলৈ কৌতুহলী বা জিজ্ঞাসু হ'ব লাগে, কিন্তু লগতে আনৰ ব্যস্ততাৰ প্ৰতিও লক্ষ্য ৰখা উচিত। কোনোবাই কামত ব্যস্ত থাকিলে তেওঁক আমনি নকৰি পাছত সুধিব লাগে আৰু কোনোবাই কিবা প্ৰশ্ন সুধিলে তাক হঠাতে নাকচ নকৰি ধৈৰ্য্যেৰে উত্তৰ দিব লাগে। নিকিতা আৰু অৰ্গই মীৰাৰ এই কথাষাৰ সদায় মনত ৰাখিব বুলি সন্মতি প্ৰকাশ কৰে।

HOTS QUESTIONS WITH ANSWERS
Q1. Why did Meera say that "Curiosity is the root of many great discoveries and inventions"?
Answer: She said this because unless humans wonder "why" or "how" things happen—just like C.V. Raman wondered why the sea is blue—they will never conduct experiments to find the hidden truths of nature.
Q2. How should we balance our curiosity with good behavior according to Meera?
Answer: We should check if the other person is busy before asking questions. If they are busy, we should wait patiently or politely ask them when they will be free instead of irritating them.
