Jonathan J. Crabtree’s Podometic Project 1968 – 2021

The Historical and Physical Foundations of Podometic Bharatiya Maths

Podometic is a long-overdue upgrade of British Arithmetic. I noticed problems with western math explanation at age 7 in 1968. So, in 1983 I set out to change the way the western world teaches mathematics. (Evidence in video.) Now, it’s time to reintroduce the original and ingenious ideas of Āryabhaṭa, Bhāskara and Brahmagupta into classes 1 to 8.  In 628 CE Brahmagupta created Zero-based maths via 18 Sutras of Symmetry. Sadly, his ORIGINal Zero-based ideas were never built into western math foundations. Instead, these were based on Ancient Greek ideas missing one, zero and negatives as numbers. Long lost, ideas that make math education simple are now available!

WHAT WENT WRONG?

Brahmagupta’s laws of zero, positives and negatives NEVER made it classrooms in 2021! In 628 CE Brahmagupta gave birth to maths with his laws of negatives, positives and zero. 200 years later, Al-Khwarizmi said 1 was ‘outside of number’. In 1228 Brahmagupta’s zero definition was absent as Fibonacci introduced 0 to Europe. In 1570, Henry Billingsley invented an illogical definition of multiplication (missing India’s zero) and the British Empire passed it off as Euclid’s. This false definition remains today. For more about the history of India’s lost Zero, watch my New Delhi talk below.

The Death Of Arithmetic: How Indian Eyes Make Maths Education Simpler & Faster | Jonathan J Crabtree

The solutions to the world’s problems of drought, congestion, pollution and poverty rely on science and science relies on maths. So, we must all return to its heritage of ancient Bharatiya maths, overlooked in history, that are consistent with laws of modern-day physics!

How might the men who created zero and base ten positional notation have taught their own children aged 5 to 13? Imagine meeting the minds of Āryabhaṭa, Bhaskara and Brahmagupta as if they were explaining maths to their own children! I also bring to life other primary-level ideas the world missed, by building upon the ideas of giants such as Euclid, Descartes and Newton.
