This is a neat clock!

14 MARCH -HAPPY PI DAY 2026❤️🌹♥️

Pi VALUE EXIST IN EVERYWHERE 🌹❤️♥️

The number pi is the reason between the length of a circumference and its diameter. That value is always the same no matter the size of the circle. Mathematically, it is an irrational number, meaning that it cannot be expressed as an exact fraction and its decimal expansion does not end or present a periodic pattern. Their numbers go on indefinitely.

From that property emerges the idea that any finite sequence of digits — such as a date of birth or telephone number — could appear at some point in its decimals. In theory, if the sequence is finite and the decimals are not repeated with a fixed pattern, there is no known mathematical reason that prevents that specific combination from appearing.

However, there's an important nuance: the fact that pi is infinite doesn't automatically imply that it contains all possible sequences. To assert that rigorously one would need to prove that pi is a normal number, that is, its digits are distributed completely evenly and randomly on base 10. To date, pi has not been formally demonstrated to be normal, although computational analyses performed on trillions of digits show a distribution compatible with that hypothesis.

In practice, trillions of decimals of pi have been calculated using advanced algorithms and supercomputers, and within those trillions of numbers already appear. From a probable point of view, the more numbers are calculated, the greater the probability of finding any specific finite sequence.

Got to teach my favorite lesson today!

Dr. Gladys West, the brilliant mathematician whose groundbreaking work helped make modern GPS technology possible, has died at 95.

Born on a Virginia farm during the Jim Crow era, West defied the odds through academic excellence, becoming valedictorian of her high school class and earning degrees in mathematics that led her to a historic career at the Naval Surface Warfare Center.

As one of the first Black women hired there, her meticulous calculations and programming transformed satellite data into accurate models of the Earth — work that became the foundation of GPS technology used globally today.

Her legacy lives on every time we navigate a road, board a plane, or use a smartphone. A quiet pioneer whose impact changed the world.

Rest in power!

The answers that some of my students get without questioning them... 😉

This meme bugs me though because this house still looks too wide for an answer of .5 cm!

When am I ever going to use math in real life??! Such a cool example in a fantastic show!

How do Helperbots run so smoothly? 🤖 Take a BTS look at how the seamless automations on stage happen!! #maybehappyending #darrencriss #tech #broadway #musicaltheatre #maybehappyending🤖

Happy Back to School to all the amazing teachers out there!

With schools going back soon, I figured it’s time to remind you of what teacher job interviews are like. 😂🙈 . If you’re a teacher, how many years into your career are you? 👀 I’m going into my 11th year! 😳 almost half way into this 25 year trial period. 🤣 . #teacher #teacherlife #teachergram #teachersofinstagram #teachertribe #school #teacherproblems #schoolmemes #backtoschool #backtoschoolshopping #teacherfollowteachers #teachersbelike
