Book review : The Man of Numbers

The book "The Man of Numbers" and its review reiterate (for western readers) that current numerals/algebra are inherited from Hindus. It starts with an example how would be current math if west is still using Roman numerals.
One interesting thing which I read first time is "It were merchants (European) who first used Hindu numerals not mathematician , because it was very practical for their accounting".

This book is on Italian mathematician Fibonacci , how he read Hindu math and presented to Europe.

Author still mix Arabic with Hindu numerals , but I guess slowly with more open researches Arabic could be omitted.

विरक्त सन्त : स्वामी रामसुखदास जी

3 जुलाई/पुण्य-तिथि विरक्त सन्त    : स्वामी रामसुखदास जी धर्मप्राण भारत में एक से बढ़कर एक विरक्त सन्त एवं महात्माओं ने जन्म लिया है। ऐसे ही सन्तों में शिरोमणि थे परम वीतरागी स्वामी रामसुखदेव जी महाराज। स्वामी जी के जन्म आदि की ठीक तिथि एवं स्थान का प्रायः पता नहीं लगता; क्योंकि इस बारे में उन्होंने पूछने पर भी कभी चर्चा नहीं की। फिर भी जिला बीकानेर (राजस्थान) के किसी गाँव में उनका जन्म 1902 ई. में हुआ था, ऐसा कहा जाता है। उनका बचपन का नाम क्या था, यह भी लोगों को नहीं पता; पर इतना सत्य है कि बाल्यवस्था से ही साधु सन्तों के साथ बैठने में उन्हें बहुत सुख मिलता था। जिस अवस्था में अन्य बच्चे खेलकूद और खाने-पीने में लगे रहते थे, उस समय वे एकान्त में बैठकर साधना करना पसन्द करते थे। बीकानेर में ही उनका सम्पर्क श्री गम्भीरचन्द दुजारी से हुआ। दुजारी जी भाई हनुमानप्रसाद पोद्दार एवं सेठ जयदयाल गोयन्दका के आध्यात्मिक विचारों से बहुत प्रभावित थे। इस प्रकार रामसुखदास जी भी इन महानुभावों के सम्पर्क में आ गये। जब इन महानुभावों ने गोरखपुर में ‘गीता प्रेस’ की स्थापना की, तो रा...

Vedic Mathematics : Shulba Sutras

From research paper "Applied Geometry of the Sulba Sutras" by John F. Price The Sulba Sutras, part of the Vedic literature of India,describe many geometrical properties and constructions such as the classical relationship           a 2 +b 2 =c 2 between the sides of a right-angle triangle and arithmetical formulas such as calculating the square root of two accurate to five decimal places. Although this article presents some of these constructions,its main purpose is to show how to consider each of the main Sulba SDtras as a finely crafted, integrated manual for the construction of citis or ceremonial platforms. Certain key words, however, suggest that the applications go far beyond this. Paper "Square Roots in the Sulbasutra" by  David W. Henderson can be read here .

Weapons in Ancient India (Bharat)

Image
Unlike fire-based weapons of current era, in ancient India or Bharat ( भारत ), weapons   were of many kinds. Weapons were called Astra ( अस्त्र ) in Samskrtam. As you may have seen in Ramayana ( रामायण ) and Mahabharata ( महा भारत ), there were various types of astras made of fire ( Agni ), rain ( Varuna ) and wind ( Vayu ). In addition, there were astras made out of venom ( Naga ), intense light ( Surya ), lightening ( Vajra ) and mountains ( Parvata ). Typically, each of these astras was named after a Deity. As an example, fire based astras had Agni or god of fire as the Deity. In addition to these Deity-based astras, trimurtis (Brahma, Vishnu and Shiva) had their own more powerful astras . Lord Vishnu’s astra was Narayanaastra . It fires a powerful tirade of millions of deadly missiles simultaneously. The intensity of the shower increases with increase in resistance. The only way of defense towards this missile, wa...
