Attraction by Jonathan Aylett

if an object’s mass
determines its gravity
explain butterflies
by Jonathan Aylett

An object’s mass is directly proportional to the gravitational force it generates, but in this haiku I am turning this on its head and asking why am I so drawn to something as light as a butterfly? The answer is obvious really (they are beautiful).

Quantum Worlds by John Hawkhead

quantum worlds
my shadow as real
as I am
by John Hawkhead

One of the experimental tests used to determine the nature of fundamental quanta such as photons is the ‘double-slit aperture test’.

A stream of photons is projected towards a barrier with two slits. The result is an interference pattern on a screen beyond the slits that demonstrates the wave-particle duality of the photon.

One explanation for this duality applies the multiverse concept and theorises that particles from parallel universes interact with the photons being projected towards the slits. In this multiverse concept, the shadow areas in the aperture pattern ‘hide’ alternative universes. The theory is that ‘shadow photons’ are affecting the the photons in the double-slit experiment.

Similarly, the terms shadows and shades are often used to describe the dead when seen crossing back into this world from the ‘other side’ as ghosts or spirits. Is it possible that our shadows are experienced in alternative universes..?

Love: Expressed in the General Theory of Relativity by Scott Edgar

Our spacetime is warped
And your celestial body
Sets me in orbit
by Scott Edgar

The scientific basis of my sciku is the General Theory of Relativity. It’s been my experience that falling in love is governed by the same laws: e.g. A distortion of spacetime that draws me to the one I love.

Shell Game by John Hawkhead

waterfall rainbows
gnats scribble probabilities
in atomic shells
by John Hawkhead

In atomic physics and chemistry, electron shells (and subshells) are thought of as a series of ascending orbits that electrons occupy around an atom’s nucleus. Shells correspond to principal quantum numbers or are labelled alphabetically with the letters used in X-ray notation. Each row on the periodic table of elements represents an electron shell.

Each shell can contain only a fixed number of electrons. The numbers of electrons that can occupy each shell and subshell arise from equations in quantum mechanics, which state that no two electrons in the same atom can have the same values of the four quantum numbers that describe an electron in an atom completely:

Principal quantum number (n)
Azimuthal quantum number (ℓ)
Magnetic quantum number (mℓ)
Spin Quantum number (ms)

Surface Tension by John Hawkhead

surface tension
she dips a toe
into my silence
by John Hawkhead

Surface tension is the tendency of at-rest liquid surfaces to shrink into the minimum surface area possible. This allows objects with higher density than water to float on its surface without becoming submerged.

Surface tension results from the greater attraction of liquid molecules to each other (cohesion) than to air molecules (adhesion).

Interactions by John Hawkhead

bosons and mesons
all the stuff we talk about
just interactions
by John Hawkhead

In particle physics, bosons are subatomic particles whose spin quantum number has an integer value and which obey Bose-Einstein statistics. Examples of bosons include the Higgs boson particle and photons (light).

Mesons are a form of boson: they’re hadronic subatomic particles composed of an equal number of quarks and antiquarks bound together by a strong interaction. Mesons are the interaction agents between protons and electrons, but are unstable outside of the nucleus, decaying to particles such as electrons, neutrinos and photons. Despite their small size (0.6 times the size of a proton or neutron) and instability, they’re observable by particle detectors and have been used to study the properties and interactions of quarks.

Empty Space by John Hawkhead

bar talk
his atoms and mine
mostly empty space
by John Hawkhead

Atoms are 99% empty space, comprised of electrons in orbits around a nucleus made up of protons and neutrons. It follows then that approximately 99% of the human body is empty space with the remaining 1% (the electrons, neutrons and protons) being particles that have existed for billions of years.

At least this is the common mental image of an atom – the planetary model, originally proposed by Ernest Rutherford in 1911 and further refined by Niels Bohr in 1913. And yet…

Researchers increasingly understand that whilst electrons occupy discrete energy levels, they don’t always behave like discrete particles. Electrons are quantum objects – an electron is partly a wave and partly a particle. Under normal conditions an individual electron isn’t traveling in an orbital path through nothingness around its nuclei, but is instead spread out in an electron cloud.

As astrophysicist Dr Ethan Siegel says, “Inside your body, you aren’t mostly empty space. You’re mostly a series of electron clouds, all bound together by the quantum rules that govern the entire Universe.”

Dancing by John Hawkhead

photons
E=mc²
dancing
By John Hawkhead

Photons are some of the most fascinating particles in the physical sciences; fundamental particles of light that are the smallest possible packets of electromagnetic energy.

Albert Einstein’s mass–energy equivalence (represented by the formula E = mc²) gives the basic relation between mass and energy, stating that under appropriate situations mass and energy are interchangeable and the same. Yet photons have a rest mass of zero – they are massless particles – therefore should they even have any energy at all? And if they have neither mass nor energy then would they even physically exist?

E = mc² is actually a special case of the more general equation E² = p²c² + m²c⁴, where E is energy, p is momentum, c is the speed of light and m is mass at rest. Since photons have no mass, this equation becomes E = pc. Effectively, photons get their energy from their momentum and can never be at rest, constantly moving.

How they move has been the subject of study for decades, with recent research suggesting that photons can behave as both particles and waves (to find out more, check out the sciku ‘Spooky Interaction’, also by John Hawkhead).

This sciku plays around with the concepts of photons, square dancing and the randomness of measuring the path of photons.

One-Word Haiku by Mark Gilbert

monopole

By Mark Gilbert

Similarly to the way that electrical charge is either positive or negative, magnetism generates both ‘north’ and ‘south’ poles. However, although single electrical charges are common (for example, a sodium ion, or an electron) a single magnetic pole has never been experimentally detected. Such an entity, a magnetic monopole, was first proposed by Pierre Curie in 1894, and its existence is predicted by various theoretical models of the universe. The search for such a monopole continues.

Like the elusive elementary particle, this minimalist haiku requires no content other than the monopole itself. It is up to the reader whether to supply the second, opposite, pole, through their own imagination, and therefore to balance the poem, or to decide that the single monopole cannot exist, leaving the haiku as a purely theoretical or imaginary quirk. I hope this may give an insight into the kind of conflicts suffered by theoretical physicists.

Spooky Interaction by John Hawkhead

explaining photons
my side of the argument
neither here nor there
By John Hawkhead

Scientists argued for years about whether photons were particles or waves, but it seems that photons can behave as both. They are now known as ‘gauge bosons’ of force-carrying particles that enable interactions between matter particles and fundamental forces, and exhibit a third property known in quantum physics as ‘excitation’.

Dark matter theory suggests the possible existence of ‘dark photons’ as mediators of interaction between dark matter particles. Some experiments have indicated that interacting photons remain connected even as they move away from each other at the speed of light; therefore, appearing to interact faster than the speed of light. Einstein’s term for this was “spooky interaction at a distance”. As with other fundamental particles, it is not possible to know the location and velocity of a photon.

A Troika of Quantum Sciku by Jeffery Shevlen

Pauli Exclusion Principle

No suborbitals
Take electron pairs whose spins
consent to agree

Aufbau Principle

Electrons always fill
The lowest energy
Sub-orbitals first

Hund’s Rule

Before forming pairs
Electrons first fill each sub-
Orbital alone

These poems are broadly about the properties of atoms. More specifically they describe three simple rules that came from of the flowering of quantum discovery roughly 100 years ago. Each describes how electrons can populate the zones around an atom’s nucleus which are called orbitals. To me haikus, scikus, wonderfully compliment the subtle interactions of the subatomic realm. Egoless nature, all the way down.

Wikipedia devotes three pages to each of the three axioms. For a more detailed explanation wikipedia is a fine place to start:

Entropy by Robert Erlandson

The second law of thermodynamics is a fundamental law of nature. One expression of this law states that the level of disorder in the universe is steadily increasing. Entropy is a measure of the system’s disorder, higher entropy means more disorder.

The image above is known as a ‘haiga’ – a coupling of poetry and imagery, the idea being to create a third art form that is greater than the sum of its parts. Below is an alternate version of the poem that takes the same starting point to create a tanka.

Axiogenesis by Alicia Sometimes

surplus baryons >
    antibaryons. Whirling
             QCD axions

I was fascinated by the etymology of this word. In Greek ‘axía’ (worth, value, merit) and ‘génesis’ (production, creation, formation, origination). Here, axiogenesis is a mechanism in which the cosmological excess of baryons (a type of composite subatomic particle) over antibaryons is generated from the rotation of the QCD axion.

Raymond T. Co & Keisuke Harigaya (2020) outline how Axions Could Explain Baryon Asymmetry – the imbalance of matter and antimatter in the universe.

The Born Rule by Alicia Sometimes

amplitudes oscillating
predictions            likely

By Alicia Sometimes

The Born Rule — a formula for assigning outcome probabilities — is extremely complex for someone like me who hasn’t studied physics but I am intrigued in its history and its purpose.

Marc-Oliver Pleinert et al. (2020) test Born’s law using many-particle interferences. This article Mysterious Quantum Rule Reconstructed From Scratch by Philip Ball was inspiring and helped me navigate some intricacies of the Born Rule and put it in a wider context.

Five and almost of a kind by Andrew Senior

I
Never let it be
Never let it be
forgot seeing is feeling
in another form
Sight the light of the blind
Sensation spent in a brain
II
I am most at home
I am most at home
in my imagination
as when science meets
crafted art, sees gravity’s
engines burning in the stars
III
Atoms are the shoes
Atoms are the shoes
of shape. We put them on to
walk this world. Smitten
with them we gallop over
its edge and into the dark
IV
How clever we are
How clever we are
to see what’s coming writing
on bark and spelling
with sticks taken from what had
already deciphered light
V
How dark a pupil
How dark a pupil
looks amplifying light’s streams
exchanging shadings
for meanings when trees convert
them only to be their lives

These five poems, “Shorts” as W.H. Auden used to call them, are part of a long series of meditations in poetry and essay about humility and ignorance, language and its limits and hence also the limits of knowledge. All in the context of science, particularly physics which is my over-riding interest.

Andrew Senior’s lifelong interest in science began as an often bed-ridden sickly child around the age of eight or nine with Astronomy. His professional career was in IT in the world of Unix/Linux servers. But Andrew never gave up an interest in science which by then had expanded from physics into biology courtesy of the best layman source there then was: The Scientific American. Long retired Andrew has continued these interests much assisted by the Internet, puzzling over the ruthless determination of humans to acquire power, gambling with their own extinction in the classic casino manner.

Foibles of research

Manipulation?

Coercion? Unwanted guests?

Foibles of research.

Academia prides itself on being fair, rational-minded and logical. Yet the practice behind these noble aims is sometimes far from that. A study by Fong & Wilhite (2017) reveals the various manipulations that can take place: from scholars gaining guest authorships on research papers despite contributing nothing to unnecessary reference list padding in an effort to boost citation rate. These instances of misconduct are likely a response to the pressures of an academic career – the demand for high numbers of publications and citation rates.

The survey of approximately 12,000 scholars across 18 disciplines revealed that over 35% of scholars have added an author to a manuscript despite little contribution (with female researchers more likely to add honorary authors than male researchers). 20% of scholars felt someone had been added to one of their grant proposal for no reason. 14% of academics reported being coerced into adding citations to their papers by journals, whilst 40% said they’d padded their reference list to pre-empt any coercion. Whilst changes to aspects of the academic system might help alleviate these issues, it’s likely to be a slow process.

Underground sound

Listening for sound

whilst deep underground requires

middle ears to hear.

Animals living in different environments will face different auditory challenges. To investigate how environment shapes evolution Koyabu et al (2017) compared middle ear morphology across terrestrial, aquatic and subterranean species from the order eulipotyphla (including hedgehogs, moles and shrews).

They found that a subterranean lifestyle involved adaptations that allow for improved sound transmission at low frequencies and reduced transmission of bone-conducted vibrations. The adaptations observed included “a relatively shorter anterior process of the malleus, an enlarged incus, an enlarged staples footplate and a reduction of the orbicular apophysis”.

Renegade liquid

Renegade liquid –

negative mass pushing back

breaking second law.

One of the fundamental aspects of Newton’s second law states is that when an object has a force applied to it, it moves in the same direction as the net force. Khamehchi et al (2017) created a liquid of negative effective mass (a Bose-Einstein condensate) that breaks this principle: when it is pushed it accelerates towards the pusher.

Road-safety

Road-safety crucial:

Engine noises distract from

predator odours.

Noise pollution can have a number of effects on wild animals. Morris-Drake et al (2016) found that road noises meant that dwarf mongooses were slower to detect a predator odour and did not increase vigilance in response to the odour (whilst mongooses exposed to normal ambient noise found the odour faster and showed increased vigilance).
