Vomiting Stars Poetica

by S.K. Tatiner

Gravity’s gone, gravel’s up. She vomits
vodka and chips in the parking lot. The Beemer
just misses. The Jag swerves like time. What luck!
Stars blue, stars yellow, stars orange, and red
fill her mouth. She gags on a galaxy. Jagged
pieces of some old self tumble in a sloppy blanket
‘round her knees. Sure, the vault of heaven
must be empty now. Sure, she’s made
the void, the void. But no–arms wide, she cries,
“Stars! Stars! Look at the stars!” Vomit
drips from fingertips. It slips down arms
and settles in pits. It twinkles and ripples and comes
to rest. “You’re warped,” she tells only herself.
“Warped enough to make new stars,” she parries.





S.K. Tatiner is a student, teacher, and lover of poetry. She is an instructor at the Writers Studio in NYC. Her chapbook, Traitor’s Bluff, was published in 2023. Vomiting Stars Poetica will appear in the October edition of the journal Tap into Poetry.

Uncertainty

by Ian Li

She believes a physicist should always be on time,
but tonight, she’s late—

moonlight pooling on her bathroom’s checkerboard tiles
as her thumb eclipses the tiny indicator window.

For now, an unobserved result is both joy and pain,
her life’s wave function not yet collapsed.

For now, her entanglement with a chronically tardy economist
remains Schrödinger’s love, simultaneously broken and eternal.

But she fears superposition is a small step away from delusion,
so her neurons fire wildly, like electrons

excited to a higher orbit, contemplating a quantum jump
to a state of motherhood.

This is no shift between hyperfine states, it’s a leap
from theoretical to practical. Perhaps she won’t make it,

or perhaps she’ll quantum tunnel right through to the other side.
If only she could peel back the future to see if it all works out.

If only she were as reliable as a Cesium clock, immaculate
and cool and golden inside, despite a turbulent world outside.

She could keep time
with this oscillating heart.

Spooky Action at a Distance

by Gary Hugh Day

They had the same print
In their living rooms, Lowry:
Coming Home from the Mill, 1928.

And whenever they glanced
At this lost world,
They felt the familiarity

Of that other place
Which was also home,
Suffusing them with a sense

Of being in two places at once,
Unsure where each began
And the other ended.

She said they were the couple
On the bottom right, moving away
From the patchy crowd

With its comedy hats and boots,
Solo dances, simple mimes,
And pavement melodramas.

All gone, like the factories
The coloured wagon and
The open doors of terraced houses.

Once more his eye is drawn
To the couple heading out of
The frame; arms linked, in step,

And he wonders if she still
Feels this ghostly closeness,
The nearest they come to touching now.

How 100 Years of Quantum Mechanics Led to the 2025 Nobel Prize in Physics

Last week, we were thrilled to learn that the 2025 Nobel Prize in Physics was awarded to John Clarke, Michel H. Devoret, and John M. Martinis for their groundbreaking discovery of macroscopic quantum mechanical tunneling and energy quantization in electrical circuits. This recognition not only honors a milestone in quantum science and technology but also beautifully aligns with the United Nations’ designation of 2025 as the International Year of Quantum Science and Technology.

Paul Cadden-Zimansky, associate professor of physics at Bard College in New York, United States, and global coordinator of the International Year of Quantum Science and Technology, explains the scientific background and historical context of the 2025 Nobel Prize in Physics in the following video:

How Does Quantum Help Us Understand Chemistry?

We talked before about how the word “quantum” often appears alongside the word
“physics,” but that quantum science is also important to fields like chemistry. Is quantum science used in chemistry?

That’s a great question! A lot of people learn about chemistry in school without understanding that quantum science lies at the heart of how and why atoms stick together to form molecules and materials. For example, consider the simplest and smallest atom, hydrogen. If you have a bottle filled with just hydrogen gas, the hydrogen atoms in the bottle aren’t bouncing around by themselves; they like to pair up with each other to make hydrogen molecules.

Yes, that’s the difference between a hydrogen atom and a hydrogen molecule; the molecules are paired-up atoms. The same thing is true of oxygen, too, isn’t it?

That’s right—oxygen molecules in the air around us that we breathe are bound together in pairs. In addition to hydrogen atoms sticking together and oxygen atoms sticking together, you can also get combinations of hydrogen and oxygen atoms.

I know one: water! H₂O—two hydrogen atoms and one oxygen atom form chemical bonds with each other to make one water molecule.

Exactly. There’s one other compound you can make out of hydrogen and oxygen, hydrogen peroxide, which is a combination of two hydrogen atoms and two oxygen atoms, H₂O₂, and is used to bleach things, like paper, to make them white. This compound isn’t as stable as water; in fact, over time, it tends to fall apart, and any other combination you make of hydrogen and oxygen will quickly fall apart.

Why is this? Why does one oxygen atom like to stick to exactly two hydrogen atoms and not just one, three, or seven? Why do oxygen atoms like to pair up with each other rather than be apart or in groups of three or some other number?

These are excellent questions that have puzzled chemists for many years. Elements like hydrogen and oxygen were first isolated and named in the late 1700s. The 1800s saw the development of the idea that all compounds were whole-number combinations of chemical atoms; however, a mystery remained as to why certain combinations of atoms were allowed and others seemed forbidden.

So, did it just seem random which combinations worked and which ones didn’t?

Not at all. From doing experiments and combining elements, chemists noticed certain patterns about how atoms combined. For example, when the elements were organized into the periodic table according to similar chemical behavior, the fact that there are eight elements in the second row matched up with the observation that elements along this row liked to make a certain number of bonds depending on their position in the row. For example, carbon, which is the 4th element in the row, likes to make four bonds; nitrogen, which is the 5th element, likes to make three bonds; oxygen, which is the 6th element, likes to make two bonds; fluorine, which is the 7th element, likes to make one bond; and neon, which is the last element in the row, doesn’t like bonding to anything.

Illustration by Serena Krejci-Papa

So oxygen, in the 6th position, likes to make bonds with two hydrogens to make water. I see the pattern you’re talking about: 6 + 2 = 8. Why eight?

This is exactly the question chemists were pondering at the start of the 20th century. There was clearly some reason behind this rule of eight, or “octet rule,” but no one understood where this eight came from. One interesting idea was that a cube had eight corners, so maybe there was something cubical about atoms that made them want to have one electron at each corner of the cube, which they could achieve by sharing electrons. But there was no evidence that there was anything cubical about the arrangement of electrons in atoms, so that model wasn’t the solution to the puzzle about the rule of eight.

So what did solve the puzzle, then?


Quantum mechanics! Almost as soon as quantum mechanics was developed, starting one hundred years ago, scientists saw how applying it to the problem of how atoms were structured—a positively charged nucleus attracting electrons to it—led directly to the patterns of the periodic table. It explained not only the rule of eight, but all sorts of other rules for how and why atoms chemically bond together. Soon, chemists not only had a quantum understanding of why oxygen likes to bond to two hydrogens to form water, but also used quantum science to find rules governing chemical combinations, compounds, and bonds that they hadn’t previously understood.

But how did quantum mechanics explain this rule of eight?


Remember that the “quantum” in quantum mechanics means something you can count. A hallmark of quantum science is showing how there are sometimes countable aspects to things that don’t seem on the surface like there’s anything there to count. In the case of atoms and bonds, the attractions and repulsions of electrons and nuclei seemed like a problem where there wouldn’t be anything countable about the possible arrangements of the electrons and the bonds they form. It was only with a quantum understanding of the wave-like nature of electrons that the hidden counting of these arrangements was revealed.

So, thinking about it, every single bond between every single atom, holding together all the materials and objects, is governed and described by quantum mechanics.

Exactly, not only all the things around us, but us as well! We wouldn’t understand how the atoms in our bodies stick together without quantum mechanics. Quantum mechanics solved some of the mysteries from a century ago about how simple compounds work, but even today, researchers are actively using quantum mechanics to reveal how more complicated materials and molecules work – including many of the ones that make up you and me.
