The philosophy of historical narrative in architectural heritageGunjan Gangey
This document discusses the relationship between historical narrative and architecture. It argues that stories and narratives have inspired art and design movements and played a major role in shaping architecture and conserving tangible and intangible heritage. The paper examines how prominent architects incorporated historical narratives into their designs through elements like planning principles, visual representations, and stylistic choices. It discusses examples like Vidhan Bhawan and temples to show how architects referenced historical narratives. The paper also introduces the concept of the 4Ps (People, Place, Purpose, Period) to analyze how historical narratives influence each aspect of architectural design. Overall, it concludes that historical narratives are important for architecture as they connect past, present and future and give buildings meaning and identity.

The principal concern of any archaeological fieldwork is to acquire new information within the context of a well-designed program of research. This program of research today ranges from goal-specific one day fieldwork to long term ventures covering many field seasons. In the field, one of the main concern of the archaeologist is the study of artifacts and features. Artifacts are the objects made or used or modified by the man such as stone tools, pottery and metal objects. A site is selected on the basis of combination of several factors, such as the period of the site, the length of the occupation, the importance of the structures and the site uniqueness in the area.
Further, the archaeological site is selected to address specific goal or goals.

Indian Mathematicians, Contribution of Indian Mathematics,Sarwar Azad
Indian mathematics emerged between 1200 BC and the late 18th century, making important early contributions to concepts like zero, negative numbers, trigonometry, and algebra. Key mathematicians during the classical period between 400 and 1200 AD include Aryabhata, Brahmagupta, and Bhaskara II. These mathematical concepts were then transmitted throughout Asia and Europe, laying the foundations for many modern areas of mathematics.
Group 4 Presentation in History of math.pptxAizaBayomo
The ancient Hindu mathematics is the oldest and most complex mathematics in the world. It developed over centuries in India and includes concepts still used today like trigonometry, calculus, geometry, and probability. Key mathematicians who contributed to its development include Aryabhata, Brahmagupta, Bhaskara, and Hemachandra. They wrote on topics like trigonometry, algebra, quadratic equations, and the Fibonacci sequence. The earliest evidence of mathematics in India comes from the Indus Valley civilization through standardized weights and the use of pi in cart wheel construction. The oldest surviving Indian manuscript on mathematics is the Bakshali manuscript from the 3rd century AD, which covers concepts of zero, fractions, square roots,
The Indus Valley Civilization was a Bronze Age civilization that flourished between 3300-1300 BCE in what is now Pakistan and northwest India. It included over 1,000 settlements of varying size, from small villages to large cities. Notable cities included Harappa and Mohenjo-Daro, which featured advanced architecture and infrastructure like planned streets, wells, and drainage systems. The civilization developed an urbanized culture and trade networks but suddenly declined around 1300 BCE for unknown reasons. While much remains unknown about the Indus Valley Civilization, it was one of the most developed ancient civilizations.
Harappa is an archaeological site located in Punjab, Pakistan that was part of the Indus Valley Civilization between 2600-1900 BC. The site contains ruins of a large fortified city that was inhabited by over 23,500 residents and occupied over 100 hectares, making it one of the largest cities of the Indus Valley Civilization. The Indus Valley Civilization had major cities like Harappa and Mohenjo-Daro along the Indus River valley and is characterized by urban planning, writing system, and standardized weights and measures.
The document provides a history of mathematics from ancient times through its development in various regions. It discusses:
1) Early counting methods and the origins of numerals in places like ancient Egypt, Mesopotamia, and India.
2) The mathematical advances of early civilizations like the Greeks, Chinese, Hindus, Babylonians and Egyptians - including concepts like zero, algebra, trigonometry, and geometry.
3) The transmission of mathematics from these early civilizations to medieval Islamic mathematics and eventually to European mathematics during the Renaissance, leading to modern developments.
The Indus Valley Civilization spanned parts of modern-day Pakistan and northwest India from 3300 BCE to 1300 BCE. At its peak during the Mature Harappan period from 2600-1900 BCE, the civilization had trade networks connecting it as far as Mesopotamia in the west and parts of Central Asia. It featured large urban settlements built along major rivers, many with sophisticated water and drainage systems. While no conclusive evidence of religious structures has been found, some seals depict figures in poses resembling later Hindu deities like Shiva, and burial practices included both burial and cremation.

Various sciences continued to develop and become more specialized in the post-Vedic period, with advances in fields like surgery, chemistry, metallurgy, glassmaking, pottery, agriculture
The document discusses 2D geometry and its importance. It explains that 2D geometry deals with coordinates on a x and y axis plane. It also discusses how classic geometry focused on compass and straightedge constructions, while modern geometry has become more abstract and complex using calculus and algebra. Additionally, it notes that 2D shapes are important for art, life skills, and future math learning as the basis for recognizing 3D shapes and geometry.
This document summarizes information about the Indus Valley Civilization. It provides details about archaeological excavations that have uncovered over 1,000 cities and settlements. The civilization had advanced urban planning with drainage and sanitation systems. The economy was based on agriculture and domesticated animals. While no single center of power has been identified, there are signs of complex decision making. Theories for the decline of the civilization include flooding, decreased rainfall, and drought.

This document summarizes the life and reign of Ivan the Terrible, ruler of Russia. It describes his complicated upbringing and early life experiences, including the murder of his father. As Tsar, Ivan initially ruled capably and consolidated Russia, but he grew increasingly paranoid and distrustful later in life after the deaths of his beloved wife Anastasia and son Dmitri, which sent him into a spiral of erratic and violent behavior. The summary captures the complexity of Ivan's character and reign as both a capable ruler but also a man whose mental state deteriorated later in life, leading to his notorious and brutal acts.

The document discusses Bandura's theory of self-efficacy as a sub-theory of social cognitive theory. It defines self-efficacy as one's beliefs in their ability to successfully perform tasks. Bandura derived self-efficacy in 1977 and later updated the model in 1997 to include individual factors influencing self-efficacy levels, with mastery experiences and perceptions of prior accomplishments being most important. Imagined experiences have also emerged as an important influence on self-efficacy.

Abstract
This paper is based on refinding / assessment of the mathematical evolution during ancient civilization of Harappa and Mohenjo-
daro during 3500-2500B.C. period. Due to lack of written documentation, any such effort has to have dependence on the relics
and remains of any civilization, from the excavated areas. Sources of excavated remains viz civil structures, sanitary system,
metalled coins and utensils, the inscription on walls, tablets and alike relics were abundance proof of the concept of mathematics
existed at that point of time. Through a scientific analytical observation a trial may be made which would reveal that idea of
symmetric geometrical figures as well as numeric operation existed in that civilization in their own way / concept. This paper is
an endeavour to assess how mathematical knowledge in Indus Valley Civilization can be considered as initialization of
Mathematical evolution.
Keywords- Indus, Harappa, Mohenjo-Daro, Lothal, Dholavira, Indus Inch, Harappan Weights, Harappan Bricks
I. INTRODUCTION
The relics of Harappa and Mohenjo-daro as found from the remains of excavations may be presumed to be during 3500 – 2000
BCE, termed as Indus Valley Civilization, spread over more then million square kilometer whose geographical area encompasses
Pakistan and northwestern India. The Indus culture was characterized by extensive urbanization with large planned cities, as seen
from the ruins of Harappa and Mohenjo-daro. There were evidences of mainly craft specialization with varied geometrical
figures which existed and long-distance trade with Mesopotamia and Central Asia.
The findings of research of any civilization can only be ascertained from various available remains and their conjoint
analysis and examinations. Those are the civil structural relics; use of metal in coins and utensils, the town planning inclusion of
sanitary planning and the road ways, etc and most importantly the conception of time measurement as well as other measurement
of materials with yard sticks.
It‟s quite natural as well as rational thinking that if such relics are viewed through quantity and qualitative angle of
measurement, every aspect of physical measures (i.e. linear, two dimensional, three dimensional) and technological known-how
involved therein reflect the existing mathematical concept in that period. Planning of civil structure, use of metallic and
nonmetallic elements and various alike metallurgical remains if viewed systematically in an integrated manner will help us in
assessing the real picture of that civilization, where in the existence of mathematically based engineering is reflected.
This research work mainly oriented towards refinding and revealing a connective process of mathematical evolution
during Indus Valley Civilization. We can‟t ignore the prehistoric contributions, which act as a shadow knowledge in establishing
its contributory preliminary mathematical evolution during any Civilization.
Eventually, such accounts of prehistoric contribution definitely help the later mathematicians in their research work on
history of the subject. So the different excavated sites of Indus Valley Civilization of Mohenjo-daro and Harappa are of immense
value as a starter of history of the subject. This civilization uncovered a very important fact that “practical mathematics” was
existing at that point of time and our ignorance about the same is due to non-availability of any proper written document and
knowledge on those accounts.
A. Ascending Order of Weights and Measures of Indus Valley Civilization
Important innovations of this civilization include standardized weights as weighting measures. Early evidence of enumeration /
counting is found among the material ruins of the Indus Valley civilization. Archaeological remains include an elaborate system
of ascending weights and measures used at that point of time. In the Indus Valley civilization we have found 500 plumb-bobs of
uniform geometrical sizes and weights. Two series were found. One is present integral method 1, 2, 4, 8, 16, 32, 64 leading to
decimal system of moderate time 10, 20, 40, 160, 200, 300, 640, 1600, 6400, 8000 and 12,800. Equivalent weights had been in
use in parts of India until recently, with conversion rates conform to the above ratios and thus help to conceptualise the basis
of an elaborate system of exchange of one commodity from another. Such measurement system, their unit of weight is
approximately 28 grams of present system which approximated to English weight “ounce”. [2]

B. Indus Inch Measures and Scales
The scales and instruments for measuring length have been excavated at major urban centres of this civilization, mainly in
Mohenjo-Daro, Harappa and Lothal. The Mohenjo-Daro scale [Figure2] is a part of a scale having length of 66.2mm, with nine
carefully sawn, equally spaced parallel lines, on average of 6.7056mm apart as from the excavations of the Great Bath in
Mohenjo-Daro. One of the lines is marked by a hollow circle, and the sixth line from the circle is indicated by a large circular
dot. The distance between the two markers is 1.32 inches (33.53mm), and has been named the „Indus inch‟. There are certain
interesting connections/correlation between the unit of length of that time and Sumerian unit of length, called „sushi‟ as exactly
equal to half of an „Indus inch‟. [2]
Fig. 2: Ruler found at Lothal (Indus Inch scale)
C. Harappan Bricks
A notable feature of the Harappan culture was its extensive use of “specific geometrical shaped” kiln-fired bricks and the
advanced standard of its making technology. In Harappa we found 15 different sizes of rectangular piped shaped Harappan
bricks (figure 3), with standard ratio of the three dimensions (length, breadth and thickness) of each brick was close to 4:2:1.
Hence knowledge of mathematical proportion did exist. Now, in the modern age this is taken into account as the optimal ratio for
efficient bonding required for a powerful brick technological erection. It is presumed that these measurements were used in the
buildings and other urban structures by the Indus people with great exactness. But Pythagorean triple theorem did not use in the
dimensions of the bricks in Indus Valley. Divakaran said that “rather than using the Pythagorean principle to generate right
angles, they might have used the property that the line through the intersection points of two circles is perpendicular to the line
joining their centres”. [4]

D. Geometrical Concept of Indus Valley Civilization
Aside measurements, the discoveries of the archaeological remains of the Indus Valley civilization in various parts of Pakistan
and northwestern India during the course of latest century revealed a culture having a esthetic sophisticated idea and
understanding of Geometrical figure which helped to date back the “Sulbasutras” by more than a thousand years. The Indus cities
well-laid out with elaborate street plans and their accurate geometrical orientation along the cardinal axes with origin have long
been considered as evidences that the Indus people had at least a working knowledge of practical Geometry stable for its
longevity. On the basis of earlier studies we can suggest that not only did these people have a practical grasp of mensuration, but
at the same time they also had an understanding of the basic principles of geometry. It can reasonably said that the people of the
Indus civilization were the self-inventors and had well versed acquaintance with the geometry of linear as well as circular

dimension and techniques of approximating their measurement of areas. The Indus civilization paid special attention to the circle
circular curvature and its variants in various geometrical designs that they made on many artifacts models having added
esthetical look (figure-4). So we can safely say that the uses of geometrical structures in shapes of cones, cylinders, barrels,
hexahedra structure, etc were in commanding use in that civilization. Carvings of them had concentric and intersecting circles
and triangles. [4]

E. Idea of Hemispherical Dimension
Seven hemispherical constructions were found at “Dholavira”, of which two could be excavated in details, which were
constructed over large rock cut chambers, having a circular plan. These were big hemispherical elevated mud brick
constructions. One of the excavated structures was designed in the form of a wheel having spokes. The other was a wheel
without spokes. These hemispherical structures bear similarity to early Buddhist stupas. The Archaeological Survey of India,
who conducted the excavation, opines that "the kind of design that is of spoked wheel and unspoked wheel also remind one of
the Sararata-chakra-citi and sapradhi-rata-chakra-citi mentioned in the Satapatha Brahmana and Sulba-sutras". [5]

F. The Numerals System and Arithmetic
The people of the Indus valley civilization achieved many notable advances in Applied Mathematical technology, with great
accuracy in their numerical systems. The oldest evidence of mathematical knowledge of Indians is found in the Indus valley
civilization. The seals and pictographic inscriptions found in the excavations of Mohenjo Daro and Harappa, indicated that the
people of that civilization had knowledge of numbers in their own way. The Harappan civilization was the mother of
mathematics from where both the concept of numbers and numerical system were born. The numerical system which was first
used by the Harappan found it‟s later development into other ancient civilizations. Therefore, it can be presented on the basis of
those relics, to be first use of mathematics in the Indian subcontinent as found in the Indus valley and dates as far back as 3500

BC. Harappans used decimal numeral system without zero with place value system. There are accounts to present numbers from
1 to 13. The numbers from 1 to 13 have been represented by the vertical strokes (as seen in figure- 6 and table- 1). [3]

G. Symbols used in 2500 B.C.
During 2500 BC the Indus number system had a base 10 (or decimal) system, containing different symbols for the numbers 1 to
9; for 10, 100 and 1000 for their multiples. Two types of numerical representation are then identified. The first (as seen in figure-
7 and table-2) contains an ordered sequence of vertical strokes representing numbers 1,2,3,4,6,7,8,9; number 5 represented by a
symbol “ꓵ”, number 10 represented by a symbol “ᴧ” and number 100 represented by a symbol “ᴧᴧ”.

ᴧ ᴧᴧ
The second is more complex in which pictorial symbols in geometric forms represent various numbers. For example
number 4 was represented with four lines, whether it is a square or rectangle or diamond or a cross. Higher numbers were
represented by additional strokes attached to the basic signs. Many of these numbers are identified from their apparent
resemblance to numbers as available in contemporary record or later number systems such as Babylonian, Chinese, Attic Greek,
Kharosthi and Asokan Brahmi. The complexity of the system was increased further as many of the numeral signs are „condensed
in an artistic way‟ or „embellished‟ to look like pictorial depictions.

II. CONCLUSION
We can conclude from this brief account of assimilated thought process that initial Mathematical knowledge / base existed
during Indus Valley Civilization in the period which reflects the existed standard of Mathematical concepts and its richness. It
will not be out of reasoning to presume that it may have acted as an impetus in furtherance of the evolution.
The story begins with the excavations of Indus Valley civilization. Although, this was a dark period since their script
remains undecoded, and no manuscripts survived to that extent. However, archaeology suggests an urban culture with well-
developed and organized cities that had regular pre plans. Moreover, there is also evidence of uniform measurements of length
and weight as used across different compositions. This uniformity existed despite an apparent absence of a central authority. The
picture of this civilization that evolves is that of a peaceful, prosperous society with agriculture, manufacturing and commerce.
One of the mathematically interesting features of this civilization is a sequence of cubic stone weights forming a regular
series of weights, which are in multiples by two for small weights, evolving into complicated binary and decimal multiples for
higher weights.
Another aspect of mathematical interest is the architecture that consisted of well-designed rectangular structures for
plots and roads. They must have known adequate of geometry.
We therefore conclude that if survey analysis of the relics available from historic excavations alike Indus Valley
civilization can be undertaken, it would add valuable material in framing Mathematical evolution since ancient period.
