Pi Day: Jab Maths Bhi Ban Jata Hai Celebration!
Aaj 14 March hai, aur yeh koi aam din nahi hai, yeh hai Pi Day! Kyunki aaj hi ke din hum math ke sabse famous constant, Pi (π), ko celebrate karte hain. 3.14 ke is number ka aaj ke date se kya connection hai? Aaj ki date 3/14 hai, jo Pi ke pehle teen digits se match karta hai. Isliye, math lovers aur number geeks ke liye yeh din ek festival ki tarah hai.
Pi Kya Hai Aur Yeh Itna Khaas Kyun Hai?
Pi, jisko ‘pie’ bhi bolte hain, ek irrational number hai, matlab iski value kabhi bhi khatam nahi hoti. Yeh circle ke circumference aur diameter ka ratio hai. Aasan bhasha mein, yeh batata hai ki kisi bhi circle ka circumference uske diameter se kitna bada hai. Iski value approximately 3.14159 hoti hai, lekin yeh infinite tak jaati hai. Pi Day humein yaad dilata hai ki math kitna interesting aur useful ho sakta hai.
Pi Day Kaise Shuru Hua?
Yeh din pehli baar 1988 mein physicist Larry Shaw ne celebrate kiya tha. 2009 mein, US House of Representatives ne officially 14 March ko Pi Day declare kar diya. Aur phir 2019 mein, UNESCO ne is din ko ‘International Day of Mathematics’ bana diya. Itna hi nahi, great physicist Albert Einstein, jinke ‘General Theory of Relativity’ ne duniya badal di, unka janam bhi Pi Day, 1879 mein hua tha. Pi ki value ko pehli baar ancient mathematician Archimedes of Syracuse ne calculate kiya tha, aur 1737 mein Leonhard Euler ne iske liye ‘π’ symbol ka use kiya.
Pi Day Kaise Manate Hain?
Duniya bhar mein log Pi Day ko different tarikon se celebrate karte hain, jaise ki Pi recital competitions aur Pi Day workouts. Yeh sab isliye kiya jata hai taki logon mein math ke liye interest badhe.
Pi Ki Significance
Pi ek infinitely long, irrational number hai, isliye iski exact value hum kabhi nahi jaan sakte. Iska matlab yeh bhi hai ki hum kisi bhi circle ka exact area ya circumference kabhi nahi nikal sakte. Egyptian mythology mein bhi Pi ka zikr hai. Egypt ke logon ka manna tha ki Giza ke pyramids Pi ke principles pe bane hain.
Kuch Interesting Facts
* Pi ki value ko yaad karne ke competitions hote hain, jismein log hazaron digits tak recite karte hain.
* Pi Day ko pie (dessert) kha kar bhi celebrate kiya jata hai, kyuki dono ke pronunciation same hain.
Toh agli baar jab 14 March aaye, toh sirf calendar hi mat dekho, Pi Day bhi celebrate karo! Yeh din humein math ki power aur beauty ko appreciate karne ka ek mauka deta hai.
