This Lisp code will produce a plot of the spatial and temporal coordinates of the quantum system in a two-state system


Lisp

(require 'quantum-system)


(defun psi ()

  (v))


(defun evolve-psi (psi)

  (dot (S) psi))


(defun plot-psi (psi)

  (plot (x psi) (y psi) :color 'blue :type :o)

  (xlabel "x")

  (ylabel "y")

  (title "Quantum System in a Two-State System")

  (show-plot))


(defun main ()

  (let ((psi (psi)))

    (loop for i from 0 to 99

          do (psi (evolve-psi psi)))

    (plot-psi psi)))


(main)


This code uses the quantum-system library to define the psi, evolve-psi, and plot-psi functions. The psi function creates a quantum system in a two-state system. The evolve-psi function evolves the quantum system in time using the S operator. The plot-psi function plots the spatial and temporal coordinates of the quantum system.


The main function creates a psi variable and then loops over the range 0 to 99, evolving the quantum system at each step. Finally, the plot-psi function is called to plot the quantum system.

chemo

Image
  The chemo cocktail churns, a metallic serpent coiling in my gut, its venom rising, a bitter tide. The sterile air, a canvas for the symphony of beeps, a haunting counterpoint to the hollowness inside. My reflection mocks from the steel embrace of the chair, a gaunt caricature, eyes hollowed, skin the hue of despair. Each breath a labored rasp, a dry leaf skittering on stone, as the serpent writhes, promising oblivion's unknown. Sleep, a fragile escape, crumbles into a twisted dream. A figure cloaked in midnight strides across the barren plains, his scythe a crescent moon, casting an inky sheen on the cracked and thirsty earth, mirroring my ravaged veins. The Grim Reaper, eyes smoldering embers in the gloom, a silent judge, his gaze a pronouncement of impending doom. His skeletal hand reaches, cold and sure, to claim my soul, but a spark of defiance flares, a flicker to regain control. I lunge, a frail wisp against the night's cold embrace, but the figure fades, leaving on...

My wife was only 32 when she died of metastatic breast cancer

Image
It was only 5 years after we found a lump in her breast.  She was a laboratory technologist in the hospital lab at the time and our medical insurance was good.  To give her the best chance, they gave her both chemotherapy and radiation to the area where the tumor had been found after surgery.  Our son was 1 1/2 years old at the time of the diagnosis and spent a lot of time at his grandmother's house during her treatments.  I went with her each time she received chemo and went through her nausea and vomiting with her after each course. In time they tattooed a tiny dot on her breast in order to guide the radiation to the right area and completed the radiation treatments.  She began recovering and within months had returned to her job at the lab. We both raised our son and went about our lives, hopeful. They did tests for tumor markers monthly without apparent return of the cancer.  One day, 5 years from the beginning she felt bad and was hospitalized. The tum...

Magic Carpet Ride

Image
 Let me take you on a magic carpet ride No silken carpet, stitched by hands unknown, But woven moonlight on a phoenix's down. With whispers of magic, we'll ascend the sky, Where stars like diamonds dance and planets sigh. Through emerald valleys, where dragons sleep, And crystal rivers secrets keep. On winds of laughter, past castles untold, With stories blooming, braver than gold. We'll chase shooting stars across the night, Their fiery whispers our guiding light. Past hidden waterfalls, where sirens sing, And wishes take flight on gossamer wing. No jeweled palace, but a moonlit bower, Where fireflies light each fragrant flower. With hearts entwined, beneath the Milky Way, We'll write our own love story, come what may. This magic we create, unseen, unheard, A tapestry woven with every shared word. So let us dance on stardust, wild and free, For the truest magic lies in you and me. With brushes dipped in dreams, we'll paint the sky, Our souls entwined, as colors dan...
