Quantum entanglement 

Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently of the others, even when the particles are separated by a large distance—instead, a quantum state must be described for the system as a whole.

Measurements of physical properties such as position, momentum, spin, and polarization, performed on entangled particles are found to be appropriately correlated. For example, if a pair of particles are generated in such a way that their total spin is known to be zero, and one particle is found to have clockwise spin on a certain axis, the spin of the other particle, measured on the same axis, will be found to be counterclockwise, as to be expected due to their entanglement. However, this behavior gives rise to paradoxical effects: any measurement of a property of a particle can be seen as acting on that particle (e.g., by collapsing a number of superposed states) and will change the original quantum property by some unknown amount; and in the case of entangled particles, such a measurement will be on the entangled system as a whole. It thus appears that one particle of an entangled pair “knows” what measurement has been performed on the other, and with what outcome, even though there is no known means for such information to be communicated between the particles, which at the time of measurement may be separated by arbitrarily large distances.

Such phenomena were the subject of a 1935 paper by Albert Einstein, Boris Podolsky, and Nathan Rosen, and several papers by Erwin Schrödinger shortly thereafter, describing what came to be known as the EPR paradox.

The EPR thought experiment, performed with electron–positron pairs. A source (center) sends particles toward two observers, electrons to Alice (left) and positrons to Bob (right), who can perform spin measurements.

Einstein and others considered such behavior to be impossible, as it violated the local realist view of causality (Einstein referring to it as “spooky action at a distance”) and argued that the accepted formulation of quantum mechanics must therefore be incomplete. Later, however, the counterintuitive predictions of quantum mechanics were verified experimentally. 

Experiments have been performed involving measuring the polarization or spin of entangled particles in different directions, which—by producing violations of Bell’s inequality—demonstrate statistically that the local realist view cannot be correct. This has been shown to occur even when the measurements are performed more quickly than light could travel between the sites of measurement: there is no lightspeed or slower influence that can pass between the entangled particles. Recent experiments have measured entangled particles within less than one hundredth of a percent of the travel time of light between them. According to the formalism of quantum theory, the effect of measurement happens instantly.It is not possible, however, to use this effect to transmit classical information at faster-than-light speeds.

Quantum entanglement is an area of extremely active research by the physics community, and its effects have been demonstrated experimentally with photons, neutrinos, electrons, molecules the size of buckyballs, and even small diamonds. Research is also focused on the utilization of entanglement effects in communication and computation.

Imagine Steve seeing a scary movie for the first time out of the ice and, since he used to think Frankenstein was terrifying, he is absolutely shook when he sees something like the Conjuring or Paranormal Activity

Steve knows it’s pretty ridiculous. He can sign up for human experimentation. He can perform like a little dancing monkey on a stage. He can fight nazis. He was frozen for seventy years only to wake up and have to fight aliens almost immediately. He’s battled with evil robots and more nazis and jumped off of buildings and out of planes with no parachute. He can do all of that without any fear.

But sit Steve down in front of a scary movie? That’s truly terrifying.

“Steve, you’re not even looking,” Bucky nags at him, sounding annoyed already.

Steve has his cell phone in front of his face blocking his view of the tv. He’s trying to distract himself by reading about Beyoncé’s new twins. It was working fine (Steve just loves Beyoncé so much. He can’t help it. Those babies are precious angels and he’s pretty sure he wants to find a way to protect them. Maybe she’s hiring a personal bodyguard.) until Bucky interrupted him. “That’s because I don’t want to look.”

“Steve it’s just a movie!”

“Uh huh,” Steve shoots Bucky an unamused look. Normally when Bucky brings home a scary movie Sam just watches it with him but Sam’s visiting his sister so he’s playing stand-in. He’s pretty sure the only reason he said yes is because Bucky can be a manipulative little shit when he wants to be. Both Sam and Bucky know he hates scary movies. The first time he watched one after the ice was with Sam. If there was any illusion in Sam’s mind that Steve was completely fearless, it ended that night. “A movie I don’t want to- CHRIST!” Steve jumps about a foot in the air when he hears the telltale music of a jumpscare.

Bucky’s face softens a little, but he does look like he’s trying to hold in a laugh. “Tell you what,” he says. He pauses the movie and reaches out to run his hand up and down Steve’s arm gently. “Go get your headphones and you can put your head in my lap and read about your beloved Beyoncé while the rest of the movie plays. I won’t be offended.”

Steve gives him a little smile. “I’d be the best bodyguard she’d ever have.”

“Sure you would, sweetheart, as long as she doesn’t like scary movies. You want a head rub too?”

Steve does.

“After Jeff’s sentencing and subsequent incarceration, I made all the necessary arrangements to go see him in prison.  Thinking I was there to comfort and console him, Jeff had something else in mind.  Jeff wanted to share the grisly details of his crimes.  He said he wanted me to hear it all from him, not someone else.  He wanted to tell me about what he had done to his victims.  He said he wanted to clear the air with me.  And he did.  

Acutely aware that I would not be able to handle this confession as his mother, I immediately assumed the role of a therapist, something I had trained for years to do.  It was the only way I could listen without losing control.

Victim by victim, he described in excruciating detail exactly what he had done to each of them.  He stressed over and over again that he always anesthetized them.  He said he was so repulsed by his own perversion that he had to get drunk to carry out the grisly task of dismembering them.  Unconscious and unaware of the gruesome experimentations he performed on them, they each had died in his arms.

‘Mom, I want you to know that I didn’t want to hurt anyone,’ he said.  ‘I made sure they didn’t suffer–I didn’t want to be mean, I always made sure that they were unconscious.’

I sat there listening, I heard every word he said, I took in every detail, but I wasn’t really there–not as his mother.  When he was finished, I kissed him good-bye and left his cell.  I drove off from the prison and straight to the emergency room in a nearby hospital and spent the night there with severe stomach cramps and uncontrollable vomiting.”

The X-Files and Stranger Things exist within the same universe and here’s why:

Hawkins, Indiana 1983

Eleven escapes from a US Department of Energy National Laboratory and over the course of the series we discover that she exists as a weapon to fight against the Russians in the cold war. But is that really her purpose? We’re supposed to believe that she developed telekinesis in the womb due to LSD and sensory deprivation experiments on her mother? Why is she Eleven and and not One and how many others are there? Who is authorizing the men who run this “US Department of Energy” lab in Hawkins? 

The X-Files can answer these questions.

Good Omens: The Nice and Accurate Prophecies of Agnes Nutter, Witch by Neil Gaiman and Terry Pratchett has always been a favorite of mine. I read it for the first time in 2008, and for the second in 2013 when I was preparing to give it out for World Book Night. 

Neil Gaiman and Terry Pratchett are two of the best fantasy writers of our time, and this novel is written by both of them, together, swapping notes. Here’s a basic outline of the plot: the end of the world. Here’s a bigger outline: Aziraphale and Crowley, angel and demon, aren’t as excited about the appearance of the Antichrist as their superiors are. They’ve gotten rather used to the human world. The Antichrist also appears to be a quite normal, though quite imaginative, boy, and under his direction, the world begins to end—Atlantis rises and aliens circle to spread their message of harmony. And through it all, Anathema Device is following along with the story thanks to the prophecies of her ancestor, Agnes Nutter, the only prophet who got everything right—which is precisely why her books never sold very well.

The book is funny, twisting, and magical. There are one or two jokes that always put me off, but they are a total of four lines in a book of many. Here are some of my favorite lines from this read:

“Evil in general does not sleep, and therefore doesn’t see why anyone else should.”

“A screaming, glowing ribbon of pain and dark light*
*Not actually an oxymoron. It’s the color past ultra-violet. The technical term for it is infra-black. It can be seen quite easily under experimental conditions. To perform the experiment simply select a healthy brick wall with a good runup, and, lowering your head, charge.
The color that flashes in bursts behind your eyes, behind the pain, just before you die, is infra-black.”

“This is how Newton Pulsifer looked as a man: if he went into a phone booth and changed, he might manage to come out looking like Clark Kent.”

“Jaime had never realized that trees made a sound when they grew, and no one else had realized it either, because the sound is made over hundreds of years in waves twenty-four hours from peak to peak.
Speed it up, and the sound a tree makes is
vrooooom.”

“Crowley said nothing. Plan A had worked. Plan B had failed. Everything depended on Plan C, and there was one drawback to this: he had only ever planned as far as B.”

“Watch out for that pedestrian!“
"It’s on the street, it knows the risks it’s taking!”

My favorite moments include the alien scene—I was laughing the whole time—the descriptions of the constant clandestine secret agents meeting up in St. James’ Park to feed the ducks, the idea that humans do a better job than demons because we have more imagination, and the poking fun at the histories and literature of witch hunting, which I understood better this time around after having taken a class on exactly that (I also understood more biblical references after my three further years of religious studies). Gaiman blends overtones of Ray Bradbury’s Dandelion Wine into a riot of a recreation story that jumps from hilarity to hilarity, all while highlighting, first and foremost, the imagination of a young boy with his friends and the friendship (fans—including me—argue romance) between a demon and an (asexual) angel who have been by each other’s side on the human world since the beginning.

The Velvet Underground & Nico - Venus In Furs (1967)

Well i am posting this as the Velvets first album, The Velvet Underground & Nico, was released 50 years ago today, March 12, 1967.

The Velvet Underground were a rock band formed in New York, America, by singer / guitarist Lou Reed, Welsh multi-instrumentalist John Cale, guitarist Sterling Morrison, and drummer Angus MacLise (who was replaced by Moe Tucker in 1965.

Accompanied by German born vocalist Nico, the album was recorded in 1966 while the group were featured on Andy Warhol’s Exploding Plastic Inevitable multimedia event tour, which gained attention for its experimental performance sensibilities and controversial lyrical topics, including drug abuse, prostitution, sadism and masochism and sexual deviancy.

Most rock bands that have followed have been influenced by the Velvets, than by any other band in the history of music.

Venus In Furs was never released as a single but was the fourth track on side one of the debut album The Velvet Underground & Nico, and is one of my favourite Velvets tracks, but i love the whole album, i can remember that i was totally blown away by its sound the first time i played it.

Shiny, shiny, shiny boots of leather
Whiplash girl child in the dark
Comes in bells, your servant, don’t forsake him
Strike, dear mistress, and cure his heart
Downy sins of streetlight fancies
Chase the costumes she shall wear
Ermine furs adorn the imperious
Severin, Severin awaits you there
I am tired, I am weary
I could sleep for a thousand years
A thousand dreams that would awake me
Different colors made of tears
Kiss the boot of shiny, shiny leather
Shiny leather in the dark
Tongue of thongs, the belt that does await you
Strike, dear mistress, and cure his heart
Severin, Severin, speak so slightly
Severin, down on your bended knee
Taste the whip, in love not given lightly
Taste the whip, now plead for me
I am tired, I am weary
I could sleep for a thousand years
A thousand dreams that would awake me
Different colors made of tears
Shiny, shiny, shiny boots of leather
Whiplash girl child in the dark
Severin, your servant comes in bells, please don’t forsake him
Strike, dear mistress, and cure his heart

This P-40K Warhawk was one of three P-40s that were heavily modified with supercharged Allison engines & bubble canopies into the experimental XP-40Q. Performance improved but still did not match the P-51, P47, or P-38 so they never went into production.

T stands on stage and shoots arrows or maybe just aims the bow a bunch.

Nessa runs on stage with a sweat band super eager, running in place.

Nessa: K! I’m here! I’m ready! I’m warm! I’m ready!

T: You’re late!

Nessa: Yes! I am! But I’m ready to do this!

T: Alright, relax a little, most of the effort is in showing up!

N: Right! - cool, yes I’m here. Can I try (goes to touch different parts of T’s body, not choosing one) … your bow?

T: You’re cute. Sure ya can… here ya go.

Nessa takes it and tries to aim it -

N: Am I doing it right??

T: You need to use your – checks Nessa’s nails – fingers - gentle but firm.

N: Now is this good?

Tries once.

I’m not good at this.

Tries to hand it back.

T: No, try! You’re doing fine - you just need good focus – and practice.

T gets behind Nessa and adjusts her.

T: Just like that.

N (slinks down to the floor): I’m not strong.

T: It’s not about being strong -

N: My hands are so small though!

T: Come on, let’s try again.

Tries to pull Nessa up.

N:  I wanna see you do it.

T: You’re not gonna learn if I do it for you! Do you want to learn?

N: I wanna be good so bad!!!

Gets up.

T: OK, here we go. Keep your focus on what’s right in front of you, don’t take your eyes off of it. Shoot strait, direct and text at least once a day.

Nessa shoots.

If Nessa makes it - they high 5 or hug or whatever.

Either way, play ends with:

Nessa: Even though I can sometimes be shitty, will you be patient with me? I really wanna be good.

CURTAIN.
