One of the coolest math facts that I know is that the only circle that fits perfectly in a 3-4-5 right triangle has an area of pi. Here's how we can prove this.

Why did ancient architects obsess over squaring the circle? It wasn’t just a mathematical riddle—it was a sacred act. To them, geometry wasn’t just shapes on paper—it was a way to encode universal truths into stone. When a square and a circle share the same area or perimeter, they symbolize the meeting of heaven (the circle) and earth (the square). And they did it all with just a compass and straight edge. Sacred geometry wasn’t woo—it was wisdom.

Why Were The Founders Of The Heliocentric Model Always Shown Holding A Compass? 👁️🧭 Newton. Galileo. Copernicus. Kepler. And Why Does Freemasonry Use The Compass & Square? Simple. The Compass Draws A Circle Not A Globe. The Square Draws Straight Lines Perfect Angles. 90°. Circle + Straight Lines. Not Curves On A Sphere. Symbols Tell The Truth If You Know How To Read Them.

.Michael Knowles dismantles the notion that 'gay marriage' is marriage: “Gay marriage doesn’t really exist in the way that a square circle doesn’t really exist. A lawmaker could come out and say, ‘I pass the square circle law,’ and a judge could come and say, ‘We defend protections for square circles,’ but nevertheless square circles would not exist."

a fun way to draw a picture from the digits of pi, made from circular arcs. draw an arc that goes 3/10 of the way around the circle. Now flip the circle over and continue the curve by drawing another arc 1/10 around, 4/10, 1, 5, 9 etc. following the digits of pi

TOPIC #4: WHY PI UNITED PRICE SHOULD BE $314,159? 👉 Before we discuss it, we need to understand what Pi is and why this project is called Pi Network, not other networks. 👉We all know that π≈3.14159. Of course, there is a long string of numbers behind it. How long is it? Infinitely long. π is an irrational number. On March 14, 2019, Google announced that pi has now reached 31.4 trillion decimal places. 👉Friends who have learned about digital energetics also know that 314159 these numbers happen to be relatively good numbers in digital energetics. 31 is the Heavenly Medicine Star, representing wealth, love, and wisdom; 141 is the Birth Qi Star, representing nobility, happiness, and easy-going; 19 is the Life Extension Star, representing responsibility, ability, and professionalism. The number 5 plays a strengthening role in digital energetics, and 159 is the strengthened ability. 👉And this number 314159 happens to be the first few digits of Pi. Is it a coincidence? What a coincidence. Pi, represented by the Greek letter π (pronounced pài), is a constant (approximately equal to 3.141592654) that represents the ratio of the circumference and diameter of a circle. It is an irrational number, that is, an infinite non-repeating decimal. In daily life, 3.14 is usually used to represent pi for approximate calculations. Using ten decimal places, 3.141592654 is sufficient for general calculations. In other words, this 314159 is a very, very important number. 👉π is also equal to the ratio of the area of a circle to the square of its radius. It is a key value for accurately calculating geometric shapes such as circle circumference, circle area, and spherical volume. A circle has 360 degrees, and interestingly, the 360th digit of pi, together with the two numbers before and after, is exactly 360! How amazing! So, can we say that the number π, 3.14159, is a perfect combination of numbers? 👉In 2011, the International Mathematical Association officially announced that March 14th of each year will be designated as International Mathematics Day. The source is the Pi of the ancient Chinese mathematician Zu Chongzhi. Zu Chongzhi had already calculated π=3.1415926 at that time, so March 14th every year is also Pi Day. 👉 So, what should this π in our human energy field be represented by numbers? That should be digital energy. The so-called digital energy means that there are always some numbers that will have a specific impact on us! 👉Every object has an energy field, including humans and the Pi Network. We can apply the energy formula E=πMN, where our energy field equals π multiplied by mental force and action force. The number π represents digital energy, M represents mental force, and N represents action force. The universe's most powerful energy is π 314159. By combining our pioneers' education, we can unite our consensus and action with the GCV records to make it the most influential cryptocurrency. 👉Using Pi Network's name, logo, Pi Day, P2Day, and open-source code, it is evident that they aim to harness Pi energy for success. 👉 If you're wondering why the price of Pi is not $314, $3141, $31415, $3141592, or $31415926, it's because the price of $314,159 is not only supported by the theory I discussed earlier but also by a 100 million USD barter. Furthermore, when we compare the price of Pi with Bitcoin's highest price of $67K, we believe that Pi should be valued higher than that. However, a price point exceeding 1 million USD would be too high. So, to sum it up, all Pi should be valued higher than $67K but not more than 1 million USD. 👉 Based on the current population of the world,,, which is around 8 billion,earth's wealth and the total amount of Pi in circulation which is around 65 billion, each individual owns an average of 8.125 Pi. The reason why we have a large amount of Pi is because we took advantage of it early on. The high price of Pi serves as an automatic lock-up for hundreds of years since Pi cannot be printed like FIAT currency. 👉Moreover, the wealth of the earth is expected to increase in the coming years, and the population will increase. Hence, it is important to have a long-term perspective and plan accordingly because it should not fluctuate much after OM. The starting price on the exchange market after OM should be at least $314,159 to discourage speculation. Let's focus on GCV and not be distracted by outside noise. Have a great day! 🌹🌹🌹 Doris Yin 🪷🪷🪷
