# Who discovered Pi?

# How many years ago was pi discovered?

The concept of PI was written about 3,912 years ago, because the earliest known textually evidenced approximations of PI date from around 1900 BC. They are found in the Egypti…an Rhind Papyrus. But only 306 years ago in 1706 AD William Jones was the first to use the Greek letter PI referring to the ratio of the perimeter to the diameter, which is constant for all circles.

# Who was the first person to discover PI?

Archimedes.

# Did Albert Einstein discover pi?

no, it was William Jones. Albert Einstein founded E=MC2.

# How many digits of pi have been discovered?

1.2411 trillion digits (1,241,100,000,000) digits of pi have been dicovered.

# How was the mathematical symbol pi discovered?

Mathematical concepts are discovered; the symbols used to represent them are not discovered. The symbols are used by convention and habit; certain symbols become universally r…ecognizable as representing certain concepts. The idea was known to the ancients in several different cultures like Egypt, although it was not calculated with accuracy. Archimedes was the first to rigorously estimate it. See link.

# Which Ancient Greek discovered Pi?

Pythagoras was credited with discovering the relationship of a radius with a circumference. Hence the term Pi (Pye).

# What famous mathematician discovered pi?

archimedes a famous greek inventor invented pi

# How was pi discovered?

The early history of N (pi) from textual sources roughly parallels the development of mathematics as a whole. Early evidence points toward use of an approximation for the len…gth of 'circumference' with respect to its 'radius' (~ 3 1/7) in the designs of the pyramids in Egypt. The Great Pyramid (2500 BC) was built with a perimeter of 1760 royal cubits (1 royal cubit ~ 20.64 inches or 525 mm) and a height of 280 cubits; the ratio 1760/280 ~ 2π ~ 6.29. (N ~ 3.14) Pi was discovered by the Greeks by a process called exhaustion. They observed that any polygon could be divided into triangles whose areas could be combined to get the area of the shape, so they tried the same thing with circles. They then factored in the radius of the circle, and they found pi. These triangles can theoretically get infinitely smaller, which is why pi is an irrational number.

# Who discovered pi in maths?

Historically, Ancient Egyptians are the first who introduced a reasonably accurate value for the ratio of the circle area and its square radius. They used an approximate value… of 3.1605 for pi The ancient Babylonians generally calculated the area of a circle by taking 3 times the square of its radius (=3), but one Old Babylonian tablet (from ca. 1900-1680 BD) indicates a value of 3.125 for pi. The first theoretical calculation of a value of pi was that of Archimedes of Syracuse (287-212 BD), one of the most brilliant mathematicians of the ancient world. Archimedes worked out that 223/71 < pi < 22/7 The Greek letter π (pi) was adopted for the number from the Greek word for perimeter "περίμετρος", first by William Jones in 1707, and later popularized by Leonhard Euler in 1737. The constant is occasionally also referred to as the circular constant or Archimedes' constant.

# How was 'pi ' discovered in the first place?

Answer You can thank the Greeks and their obsession with Geometry for this one. They found when you divided the circumference of a circle by its area I think you get 3.…141...... or pi. Actually the ratio Pi is obtained by dividing the circumference of any circle by the length of the diameter. There is also some evidence which possibly indicates that this ratio (Pi) was known to the ancient Egyptians ca 2500 b.c.e.

# Who discovered pi and screamed eureka?

Archimedes was the first to discover it accurately but pi was around in the time of early egyptians and mesopotamians...so pi has been around for a long time Archimedes did, o…ne day while he was in the bath tub. The sudden realization made him so excited that he ran down the hall yelling "Come here, Watson, I want you !" Eventually he reached the kitchen, where the door slammed behind him, and an apple fell on his head, stunning him temporarily. Realizing the gravity of his situation, he reached for the key dangling from the wall by a string, but it gave him such an electric shock that he ran back out of the kitchen and up to the bath chamber to fetch his robe. His heart pounding now, he sank onto his bed, marveling and exclaiming "What hath god wrought!" at the wonder of it all, and as he tried to relax and to calm himself, he muttered to himself in a soothing tone, "We have nothing to fear but ... fear itself."

# When was pi first discovered?

It was discovered that pi was actually used in building the pyrimads of Giza around 2600-2500BC. The perimter of the pyrimads were 1760 cubits and the height of the pyrimad wa…s 280 cubits. This is a ratio of 2pi. 1760:280 = 2pi. This is the first recognition of pi.

# Which Greek thinkers discovered the value of pi?

None because the exact value of pi has never been finally figured out and that all we know is that when the circumference of a circle is divided by its diameter that it is the… value of pi which has been worked out to billions and billions of decimal places and still its exact value remains undiscovered.
