What is the origin of pi?
What Does “Pi” Mean, And Where Does It Come From?
Pi is the Latin name of the sixteenth Greek letter, π. (Mathematic notation borrows from a multitude of alphabets and typefaces.) The first recorded use of π as a mathematical symbol comes from the Welsh mathematician William Jones in a 1706 work called Synopsis Palmariorum Matheseos, in which he abbreviated the Greek περιϕέρεια, (meaning “circumference,” or “periphery”) to its first letter: π.
What does pi mean in mathematics? The mathematical pi is defined as “the ratio of the circumference of a circle to its diameter.” It’s also known as Archimedes’ Constant, after the ancient Greek mathematician of the same name, who, in addition to coming up with an algorithm for calculating pi, also invented an early type of irrigation pump called the Archimedian screw. Very medieval-sounding, but we digress.
What makes pi so magical is that it doesn’t matter how big or small the circle may be: the pi ratio remains the same. Pi is what’s known as an irrational number, which means, in part, that “it can never terminate or repeat when written out in decimal form.” As far as we can tell, it goes on forever, which is a bit mind-boggling. Computers have calculated pi to decimal places in the trillions. It is also a transcendental number, a concept that exceeds the scope of this post but is interesting in and of itself.

International Men’s Day 2024
Men Leading By Example
On November 19 International Men’s Day celebrates worldwide the positive value men bring to the world, their families and communities.
International Men’s Day encourages men to teach the boys in their lives the values, character and responsibilities of being a man. Mahatma Gandhi said, “We must become the change we seek.” It is only when we all, both men and women, lead by example that we will create a fair and safe society which allows everyone the opportunity to prosper.
International Men’s Day is an opportunity for people everywhere of goodwill to appreciate and celebrate the men in their lives and the contribution they make to society for the greater good of all.
International Men’s Day is annually held on November 19 to improve gender relations and promote unity
World Toilet Day 2024
What’s UN World Toilet Day?
In 2013, a joint initiative between the Government of Singapore and World Toilet Organization led to Singapore’s first UN resolution, entitled “Sanitation for All”, calling for collective action to address the global sanitation crisis through the commemoration of World Toilet Day. The resolution was co-sponsored and adopted by 122 countries at the 67th session of the UN General Assembly in New York. On July 24, 2013, World Toilet Day on 19 November became an official UN day.
Each year UN World Toilet Day calls on the global community to do more to address the sanitation crisis. The theme for 2016 is “Toilets and Jobs.” World Toilet Day is THE day for action. It is the day to raise awareness about all the people who do not have access to a toilet, and the urgent need to end the sanitation crisis. And it is the day to stand up (or sit down or squat if you prefer) to do something about it.
Singapore's first UN resolution adopted; now, every Nov 19 is World Toilet Day
The United Nations (UN) has agreed to mark World Toilet Day on Nov 19, thanks to a Singapore initiative.
Singapore had tabled the resolution, Sanitation for All, to raise awareness of the global challenge of sanitation and toilets.
It is the first time Singapore, since it became a UN member 48 years ago, had put a resolution before the UN's General Assembly of 193 members. The resolution was supported by 120 countries, said the the Ministry of Foreign Affairs and Ministry of the Environment and Water Resources in a joint statement on Wednesday.
World Toilet Day
World Toilet Day (WTD) is an official United Nations international observance day on 19 November to inspire action to tackle the global sanitation crisis. Worldwide, 4.2 billion people live without "safely managed sanitation" and around 673 million people practice open defecation. Sustainable Development Goal 6 aims to "Ensure availability and sustainable management of water and sanitation for all". In particular, target 6.2 is to "End open defecation and provide access to sanitation and hygiene". When the Sustainable Development Goals Report 2020 was published, United Nations Secretary-General António Guterres said, "Today, Sustainable Development Goal 6 is badly off track" and it "is hindering progress on the 2030 Agenda, the realization of human rights and the achievement of peace and security around the world".
World Toilet Day exists to inform, engage and inspire people to take action toward achieving this goal. The UN General Assembly declared World Toilet Day an official UN day in 2013, after Singapore had tabled the resolution (its first resolution before the UN's General Assembly of 193 member states). Prior to that, World Toilet Day had been established unofficially by the World Toilet Organization (a Singapore-based NGO) in 2001. UN-Water is the official convener of World Toilet Day. UN-Water maintains the official World Toilet Day website and chooses a special theme for each year. In 2020 the theme was "Sustainable sanitation and climate change". In 2019 the theme was 'Leaving no one behind', which is the central theme of the Sustainable Development Goals. Themes in previous years include nature-based solutions, wastewater, toilets and jobs, and toilets and nutrition. World Toilet Day is marked by communications campaigns and other activities. Events are planned by UN entities, international organizations, local civil society organizations and volunteers to raise awareness and inspire action.
Toilets are important because access to a safe functioning toilet has a positive impact on public health, human dignity, and personal safety, especially for females. Sanitation systems that do not safely treat excreta (feces) allow the spread of disease.Serious soil-transmitted diseases and waterborne diseases such as cholera, diarrhea, typhoid, dysentery and schistosomiasis can result.

We Live In Very Interesting & Funny Times
1. We live in times where we see many humans, but not humanity.
2. We live in times where the rich has more rooms than children and the poor has more children than rooms.
3. We live in times where smart phones bring you closer to those who are far, but distance you from those who are closer.
4. We live in times where we open Facebook, more than Holy Book.
5. We live in times where a single mother can look after 10 children, but 10 children can't look after a single mother.
6. We live in times where the rich walk miles to digest food, while the poor walk miles to search for food.
7. We live in times where women are paid to be naked, while others have no clothes to cover their nakedness.
8. We live in times where our contact lists are huge, but our relationships are poor.
9. We live in times where our possessions are more, but our appreciation is less.
10. We live in times where we know how to earn a good living, but somehow forget how to live good.
11. We live in times where many know the price of everything, but not the value of anything.
Indeed, we live in a strange world. ❤
