केपलर का जन्म सन् 1571 में दक्षिणी जर्मनी के एक शहर वाइल में हुआ था। अभी वह चार साल के ही थे कि चेचक के शिकार हो गए। इससे उनकी आँखें बहुत कमजोर हो गईं और हाथों से लगभग अपंग ही हो गए। इन सब बाधाओं के बावजूद केपलर बचपन से ही एक प्रतिभाशाली विद्यार्थी थे। चर्चों की व्यवस्थापक संस्था ने उनका भविष्य निर्धारित कर दिया और वे धर्म विज्ञान का अध्ययन करने के लिए ईसाइयों के ‘गुरुकुल’ में दाखिल हो गए।
उन्होंने ट्यूविंजेन विश्वविद्यालय की छात्रवृत्ति उपार्जित की। यहाँ वे कोपरनिकस के विचारों के संपर्क में आए, जैसे किस प्रकार ग्रह-नक्षत्र सूर्य के चारों ओर परिक्रमा करते हैं। गणित पर आधारित नक्षत्रों की गतिविधि का ‘सूक्ष्म’ अध्ययन जहाँ उनका विषय था, वहाँ उन्होंने मूर्त आकृतियों, धन वर्ग, चतुष्फलक, अष्टफलक, द्वादशफलक तथा विशंतिफलक की पूर्णता के संबंध में भी एक अंतर्सूत्र सा, एक ‘स्थूल’ नियम सा प्रस्तुत करने की कोशिश की।
केपलर ने विज्ञान के अन्य क्षेत्रों में भी अन्वेषण किए। मानव दृष्टि तथा दृष्टि विज्ञान के संबंध में जो स्थापनाएँ उन्होंने विकसित कीं, उनका प्रकाश के ‘अपसरण’ के क्षेत्र में बहुत महत्त्व है। इस पुस्तक में जोहैनीज केपलर की जीवनकथा का रोचक एवं प्रेरक वर्णन है।

India's Glorious Scientific Tradition
- Author Name:
Suresh Soni
- Book Type:
- Description: Most common people feel that the first rays of science broke out in the west and thus started the wheel of development throughout the world. There was darkness in the field of science in the east. As such, there is a tendency to follow the west. The unawareness of the fact that we had a scientific tradition and a scientific point of view often puts us on the backfoot. This book is an attempt to bring to light the glorious tradition that we had in various streams of science. Today’s generation can get a direction from reading this literature; they can gain self-respect and hold their head high for being the major contributors to science and technology. Besides acquainting the modern generation with India’s contributions in the field of science, this book will also inspire them to study more and experiment.

- Book Type:
- Description: कर्म शब्द ‘कृ’ धातु से निकला है; ‘कृ’ धातु का अर्थ है—करना। जो कुछ किया जाता है, वही कर्म है। इस शब्द का पारिभाषिक अर्थ ‘कर्मफल’ भी होता है। दार्शनिक दृष्टि से यदि देखा जाए, तो इसका अर्थ कभी-कभी वे फल होते हैं, जिनका कारण हमारे पूर्व कर्म रहते हैं। परंतु कर्मयोग में कर्म शब्द से हमारा मतलब केवल कार्य ही है। मानवजाति का चरम लक्ष्य ज्ञानलाभ है। प्राच्य दर्शनशास्त्र हमारे सम्मुख एकमात्र यही लक्ष्य रखता है। मनुष्य का अंतिम ध्येय सुख नहीं वरन् ज्ञान है; क्योंकि सुख और आनंद का तो एक न एक दिन अंत हो ही जाता है। अतः यह मान लेना कि सुख ही चरम लक्ष्य है, मनुष्य की भारी भूल है। संसार में सब दुःखों का मूल यही है कि मनुष्य अज्ञानवश यह समझ बैठता है कि सुख ही उसका चरम लक्ष्य है।
