Katherine Johnson: The Mathematician Who Launched Astronauts into Space and Women into STEM 🚀👩‍🚀

In the vast expanse of the cosmos, where men first dreamed of reaching the stars, Katherine Johnson calculated the path that would get them there. This story isn't just about trajectories and orbits; it's about a woman whose brilliance in mathematics helped break the barriers of space and gender.

Johnson's journey began in White Sulphur Springs, West Virginia, where her curiosity and intelligence shone from an early age. Despite encountering segregation and sexism, she charted a course that would lead her to NASA, where her skills became indispensable to the success of the U.S. space program. Her calculations were critical to the success of the Mercury missions, including John Glenn's pioneering orbital flight, for which he specifically requested Johnson verify the computer's numbers. "If she says they're good," Glenn said, "then I'm ready to go."

But Johnson's contributions went beyond Mercury. She also played a role in the Apollo missions, including the first lunar landing, and her work on orbital mechanics laid the groundwork for the Space Shuttle program and plans for a Mars mission.

Her legacy is a beacon for women and people of color in STEM, symbolizing the power of intelligence and perseverance to overcome societal constraints. Johnson's story teaches us that the path to the stars is paved with determination, hard work, and an unwavering belief in one's own abilities.

Katherine Johnson's calculations helped lead humanity to the moon, but her impact extends far beyond the numbers. She charted a course for future generations of women in STEM, proving that the sky is not the limit—it's just the beginning. As we look up at the stars, we remember her legacy, not just as a mathematician, but as a trailblazer who launched us into a new era of exploration and equality.

Pie for my weekly challenge and for PiDay!

[badsciencejokes]

Have a happy Pi Day. How are you celebrating Pi Day?

[carnivuar]

Happy PI(E) day everyone!!

Im a little late in the day to posting this so i hope im not burried but its them!! I haven’t drawn just Ghost and Toast in a while, im always posting my lore all the time so im hoping to change that.

Im also introducing a new paranormal entity called “Si-Pi”! Hes made up of binary code and the power of the never ending formation of 3.14 which makes him inherently stronger than most code entities they have encountered- what a coincidence for them.

He’s friendly I promise :)

IMPORTANT MATH PSA

You know how people always ask if pi contains all strings of integers and then people answer "no pi is not normal". So FIRST OF ALL normality is wayyyy too strong of a property here. A number in which all finite sequences appear is called *disjunctive*. A normal number is one in which all integer sequences are uniformly distributed, much stronger property.

That being said, it is not known (but strongly conjectured) that pi is disjunctive. In fact, every sequence of eleven digits or less appears in the first 2.7 trillion digits of pi.

In conclusion:

Happy Pi Day! 🥧

This sea anemone in Channel Islands National Marine Sanctuary isn’t a pie and we definitely wouldn’t recommend eating it. BUT, sea anemones do exhibit radial symmetry, meaning they’re symmetrical around a center point, like a pie, and you could measure their circumference using pi.

Our national marine sanctuaries and marine national monuments are teeming with organisms that display radial symmetry. Can you name any other radially symmetrical marine organisms?

Pi Day

Pi Day is on March 14, and any day that combines fun, education, and pie is a day worth celebrating! Pi, also known by the Greek letter “π,” is a constant value used in math that represents the ratio of a circumference of a circle to its diameter, which is just about 3.14….15…9265359… (and so on). Not only that, but the fourteenth of March is also Albert Einstein’s birthday, so all together it’s nothing short of a mathematician’s delight.

When is Pi Day 2024?

The beautiful constant pi (π) is celebrated by mathematicians around the world on National Pi Day on March 14.

History of Pi Day

To learn about pi, we need to go back a few thousand years and learn about this elusive number. The value of pi was first calculated by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

However, it was first baptized with the Greek letter as its name when William Oughtred called it as such in his works dating back to 1647, later embraced by the scientific community when Leonhard Euler used the symbol in 1737.

But how did Pi Day end up in a country-wide phenomenon? For that, we need to travel to the Exploratorium in 1988 San Francisco, where it was thought up by physicist Larry Shaw.

Shaw linked March 14 with the first digits of pi (3.14) in order to organize a special day to bond the Exploratorium staff together, where he offered fruit pies and tea to everyone starting at 1:59 pm, the following three digits of the value. A few years later, after Larry’s daughter, Sara, remarked that the special date was also the birthday of Albert Einstein, they started celebrating the life of the world-famous scientist.

Pi Day became an annual Exploratorium tradition that still goes on today, and it didn’t take long for the idea to grow exponentially, hitting a peak on March 12, 2009, when the U.S Congress declared it a national holiday.

Now, celebrated by math geeks all around the circumference of the world, Pi Day became a pop culture phenomenon, with several places partaking in the activities, antics, observations and all the pie eating they can.

Traditions of the day

Pi Day gives math enthusiasts the opportunity to celebrate their love for numbers and the enigma that is the infinite pi.

Since 1988, the day has been celebrated at the San Francisco Exploratorium. The first celebration was organized by Larry Shaw, who worked as a physicist at the center. The staff participated by marching around the exploratorium and consuming fruit pies. This tradition has lived on since. Math lovers talk about math, host get-togethers, and have pi recital competitions. In schools, teachers arrange scavenger hunts, pie bake sales, and even Pi Day workouts to stimulate more interest in learning and practicing mathematics. Those folks who work in food marketing also love to get involved, so keep your eyes peeled for some discounts, deals, and freebies on pies, it’s going to be an extra tasty day.

Pi Day Activities

Enjoy pie of course: Pi is a homophone of pie: the 2 words are pronounced similarly, but are spelled differently and mean different things. Celebrate Pi Day by eating lots of pie! Pizza, cherry, apple, you name it!

Throw a potluck party: Everyone loves to show off their family pie recipe. Make it a potluck and everyone will be inclined to bring their favorite pie to Pi Day, whether it's a pizza pie, a pot pie, a savory pie, or a sweet pie. Make a playlist that features songs like "I Like Pie, I Like Cake" and "American Pie.”

Try making a new pie: Ever tried to make a pie before? Now's your chance to bake your very own. Not into the sweet stuff? Don't worry, there are various savory pie recipes out there so that everyone can enjoy the warm buttery flakiness that comes with a fresh baked pie.

5 Facts About Pi

People compete in memorizing it: Rajveer Meena has the record for memorizing the most decimal places of pi at 70,000.

It’s used as stress tests for computers: Computing pi is a kind of “digital cardiogram” for computers.

A Givenchy men’s cologne is named pi: So you can smell like pi too if you are the intellectual and visionary kind.

It has other names: Pi can also be named “Archimedes’ constant,” or “Ludolph’s number.

It has been used by heroes: Spock foils the evil computer by having it calculate pi’s value in Star Trek’s episode “Wolf in the Fold”

Why We Love Pi Day

Pi is infinitely cool: Pi (π) is the ratio of a circle’s circumference to its diameter — and amazingly for all circles of any size, pi will always be the same. Pi is an "irrational number," meaning its exact value is completely unknown. Scientists have calculated billions of digits starting with 3.14159265358979323…, but no recognizable pattern ever emerges. We could continue on and on until infinity and we'd still have no idea what digit might emerge next.

Pi sounds like pie: If you are a nerd that likes pies this holiday is pretty much the best combination of the most interesting things in life: pie and mathematics. And of course that means that in order to celebrate abstract mathematical items that are somewhat irrational the obvious solution is to incorporate pie into the holiday.

Pi links mathematics to the real world: Maybe when you were in math class, you stared off into space wondering why on earth 'logs' or 'proofs' mattered so much. Pi is the answer, well at least, one of the things that links math back to real world uses. Because pi is linked to circles it is also linked to cycles, things like calculating waves, ebb and flow, the oceans tides, electromagnetic waves and much more. In addition, many natural world phenomena can also be calculated with pi — like the shape of rivers, the disc of the sun, the spiral of DNA and even the pupil of an eye.
