A sentence is a group of words that expresses a complete idea. A sentence has two components – subject and predicate.

This remaining part is called predicate. Note the subject and predicate in each of the following sentences. Also note that the verb form in each sentence depends on the subject.

Great Scientists Have A Questioning Mind Summary
Great Scientists have a Questioning Mind हा उतारा डॉ. ए. पी. जे. अब्दुल कलाम यांनी लिहिला आहे. डॉ. कलाम २००२ ते २००७ या कालावधीत भारताचे राष्ट्रपती होते. वैज्ञानिक संशोधन आणि भारताच्या संरक्षण तंत्रज्ञानाच्या आधुनिकिकरणासाठी दिलेल्या योगदानामुळे त्यांना भारतरत्न या पुरस्काराने सन्मानित करण्यात आले होते. या उताऱ्यामध्ये डॉ. कलाम यांनी महान भारतीय वैज्ञानिक सी. व्ही. रामन यांच्या उल्लेखनीय कार्याची माहिती दिली आहे.
अत्यंत बुद्धिमान असलेल्या सी. व्ही. रामन यांना लहानपणापासूनच विज्ञानाची आवड होती. रामन यांचा असा ठाम विश्वास होता, की आपल्या प्रश्नांची उत्तरे शोधण्यासाठी वैज्ञानिकांनी प्रयोगशाळांवर अवलंबून राहण्यापेक्षा उघड्या डोळ्यांनी सभोवतालच्या जगाकडे पाहावे.
आपल्याभोवती नैसर्गीकरीत्या घडणाऱ्या अनेक घटनांची उत्तरे शोधण्यासाठी / घटनांमागची कारणं शोधण्यासाठी तरुण पिढीनं जिज्ञासू असावे असे त्यांना वाटत असे. प्रकाश आणि ध्वनी शास्त्राच्या क्षेत्रात त्यांनी प्रेरणादायी कार्य केले आहे. ‘रामन परिणाम’ (Raman Effect) या शोधासाठी त्यांना १९३० मध्ये नोबेल पुरस्काराने सन्मानित करण्यात आले. रामन हे हा पुरस्कार मिळवणारे पहिले आशियाई व्यक्ती ठरले.
