"Okay, so can anyone tell me what a sideways parabolic equation is similar to in terms of how it is shaped?" Nezuko asked, eyes scanning the room full of confused faces upon hearing the words uttered from her mouth.
"I dunno... a sideways oval?" one boy called from the back of the class.
"You are partially correct!" she replied, tapping her foot against the floor. "More specifically, the graph resembles that of a half-elliptical shape. Really fun fact- the full elliptical shape resembles how the orbit of a modern spacecraft is around the Earth, since only natural celestial bodies can move in a perfectly equatorial orbit. In fact, this is entirely because of how the earth rotates and tilts on it's axis- all manmade airborne space and aircrafts follow an elliptical and fixed flight path as per the itinerary provided to the pilots," she explained.
Many "ooh's" and "aah's" came from the plethora of students sitting at their desks, and Sanemi just barely restrained himself from letting his jaw drop to the floor- the amount of wit and social charisma this young lady possessed was insane.
"On February 20th, 1962, during the Cold War- United States Marine Corps Aviator, engineer, astronaut, businessman and politician John Herschel Glenn Jr. became the first person to orbit the earth, accomplishing three orbits in ten hours," she continued, pacing back and forth across the classroom before chuckling.
"Tall, fair, handsome and golden. IQ above 100 and an American, no less- definitely my type, if you ask me."
Most of the students instantly burst into giggles upon the joke she cracked.
The explanation continued itself as the words seamlessly constructed themselves into sentence after sentence in her mouth, as if it belonged on her tongue, being told to the world on a little podium for her to stand on.
"According to the complex equations calculated by hand by NASA's smartest mathematicians, the results depicted flight trajectories and the exact orbit path of the Friendship 7 space vessel. The apogee was the farthest distance it could go while still being within the field of Earth's gravity, and the perigee was the closest it could go to Earth without being pulled into the atmosphere before the orbit paths could be completed. Think of those flight paths as a sideways parabola, since everything in this world is three dimensional," she explained.
What in the hell? Was this math class or a bloody physics college course?
Despite Sanemi's internal protests, he listened to Nezuko continue to lecture on while she drew an example diagram of the intended flight path on the board.
"Now- when the capsule LANDS is when it shifts from an elliptical orbit... to a parabolic orbit. This is defined via Euler's Method. The 'go' point before the rocket launches into orbit can be anywhere on the globe, however- where it launches doesn't impact the 'no-go' point, rather, the amount of time it orbits impacts it. The spacecraft needs to be pulled down at exactly the right coordinates at exactly the right time, give or take only twenty square miles maximum of the exact location, otherwise John would've burnt up to a crisp in the empty void of nothingness, or he would've been lost to space forever after being launched from Earth's gravity."
Slight murmuring came from the students sitting at their desks, and Nezuko swore she saw 90% of the class crease their brows in fear.
"Luckily, the coordinates weren't approximated. The 'no-go' point's coordinates were calculated down to the last decimal, and via the Graham-Schmidt Orthogonalization Algorithm, the coordinates were verified and the location was confirmed as the Bahamas- thus, John Glenn's life was spared and he lived to once again go to the moon."
Sucking in a long breath after speaking, she turned to the students gawking in awe. Her pink eyes fixating on the one who's leg was wrapped in bandages and a brace, she smirked and winked.
Ah. The boy Sanemi threw out the window a few days ago.
"And that, ladies and gentlemen, is why you need math in the future. Thank you ever-so-much for attending my Ted-Talk, any questions?"
No questions, no clamor of unruly behavior or chatting without permission- nothing. Just stunned silence.
"Hehe, alright. Then I guess I get to keep my A+ for another day."
As she walked back to her desk, she tapped Sanemi on the shoulder and flashed him a look. "Oh, and Mr. No-Eyebrows? That chalkboard of yours is incredibly squeaky- I think it's high time we replace it with something a bit more... practical and advanced," she murmured.
Then she winked, and the finger that was tapping her teacher's shoulder then flicked it.
Needless to say, Nezuko was not spared from Sanemi mercilessly chasing her down the hallways before tackling her to the floor and pulling at her uniform collar to force her to apologize. Whereas most other students would burst into tears, she was in fits of hysterical, explosive laughter.
"Ahahaha! Okay, okay, I'm sorry! I'm sorry- just pleaseletmegoowwwahahahaha!"
