Quantum Mechanics


The First Law of Thermodynamics, also known as the Law of Conservation of Energy, states that energy cannot be created or destroyed, it can only be transformed or transferred from one form to another.

The light filters through the window earlier each day. Mornings are cold but spring is here and it hasn’t been a bad winter. Not like last year when we lit a fire every evening and the cat melted in front of it, becoming liquid. There has been little rain and very few frosts. The ground is hard. Dry. Bushfire season will be dangerous, according to the news.

I stand at the kitchen counter and pop a coffee pod into the Nespresso, slide my Tinker Bell mug under the spout and wait for the thick, black liquid to pour from the nozzle. Outside, the daffodils stand tall declaring winter is at its end. Buds are sprouting on the bare trees and some of the magnolias have dared to bloom. A kookaburra laughs in the gum tree at the front of the house. The whir of the machine stops and the pod clunk-clunks down into the receptacle, breaking my reverie on the garden. I grab my coffee and sit down at the table with my computer. It’s been months since I’ve written, months since I’ve thought about writing.

Years ago I blogged regularly, an almost daily habit of recording my life, of making meaning out of madness. But my storyline changed and I didn’t know how to segue into the next scene. I was leading a new life so divergent from the previous incarnation you’d suspect I wasn’t the same person. And I wasn’t. Which had kind of been the plan all along. ‘If I’m not different at the end of this,’ I wrote early on, ‘I won’t be better.’

We all have two lives, a dubiously attributed quote begins (really? Confucius? I think not), the second starts when we realise we only have one. (Tom Hiddleston? Perhaps.)

I’ve already lived more than twice in this current span of time. And yet, my handwritten journals would suggest that little has changed. Things look different now, sure; daily tasks and duties, responsibilities reshuffled and realigned. So much chaos from the past has settled out but my desires have not changed. My humanness – my energy, although transformed – is the same.


Heat is a form of energy. It always flows from the hotter body to the colder body. Heat can be transferred via conduction, convection or radiation.

In bed, my partner snuggles behind me. Dialogue from my old Bikram hot yoga class pops into my head. ‘From the side you should look like a Japanese ham sandwich,’ the instructor shouts during Pada-Hasthasana, the forward fold, ‘no gap anywhere’.

‘I’m very tactile,’ I tell him when we first meet, ‘you’ll probably get sick of it after a while.’ He laughs, eyes sparkling. Every night, going on four years, our bodies touch from head to toe. His chest against my back, breath on my neck, legs pressed against mine, feet tangled. No gap anywhere. The heat radiates between us and eventually drives us to roll over and reverse the position. We dance like this for most of the night.


Pauli’s Exclusion Principle says that every electron must be in its own unique state. In other words, no electrons in an atom are permitted to have an identical set of quantum numbers.

You might be reading this on your phone, holding it in your hand. Or on your computer. You pressed some keys to access it. You touched them.

Didn’t you?

Atoms are made up of three particles. A nucleus that contains most of the mass, protons, and electrons. Electrons are negatively charged and can exhibit characteristics of both particles and waves. Particles are attracted to particles with the opposite charge and repel similarly charged particles. So electrostatic repulsion prevents electrons coming into direct contact with each other in both an atomic and literal sense.

This, and Pauli’s Exclusion Principle, also prevents you, me, us…from touching anything. Instead, we hover above things at a microscopically small distance. Gaps everywhere. The sensation of touch is simply our brain’s interpretation of our electrons’ interaction with other electrons in the electromagnetic field, the medium through which electron waves propagate.


Electromagnetic fields are physical fields produced by electrically charged objects. They affect the behaviour of charged objects within the vicinity of the field. Electromagnetic radiation refers to the waves of the electromagnetic field which radiate through space-time, carrying electromagnetic radiant energy.

The human heart is the first organ to function during fetal development at approximately 20 days. The brain doesn’t begin to function until about 90 days. First the heart, then the head.

The heart generates an electrical field of up to 60 times greater in amplitude than that created by the brain and the electromagnetic field of the heart can be measured up to several feet away from the body. When individuals are in close proximity, their electromagnetic fields interact.


Perhaps, in the end, all we can touch is hearts.

Science Sunday | Chemistry 101

Chemists joke about the dangers of dihydrogen monoxide. Depending on its form – solid, liquid, or gas – direct contact with it can burn you, or freeze the tissues and fluids in your skin. If you ingest significant quantities it can kill you. Of course, not ingesting enough will kill you too. According to these consequences, dihydrogen monoxide sounds like a nasty chemical. But it is just the humble water molecule. (I never said chemists make good jokes.) All of the dangers are true, though. Dihydrogen monoxide – H2O – water – is a chemical which can burn you, cause frostbite, or dilute the salts in your blood so much that you die from water intoxication (hyponatremia). And just like water, chemicals are everywhere. Everything that you can see, smell, touch, and taste is made of chemicals. And everything you can’t.

It is impossible to see a single atom, even with the most powerful microscope. Although, scientists have managed to photograph an atom’s shadow. How few atoms does it take to cast a shadow? Just one. But while one atom alone cannot be seen, when many are joined together we see them everywhere. Or, we see the things they make up. Water. Trees. Cars. Houses. Hearts.

The Periodic Table of the Elements lists the species of atoms that have been discovered. There are one hundred and eighteen in total but only ninety-four occur naturally. The rest are synthetic and must be made in laboratories. Everything around us is a combination of these ninety-four elements.

At room temperature, some elements exist as liquids, some as solids and some as gases. They can be volatile like the metal sodium: soft, silvery white, and highly reactive. If you’ve ever seen a tiny piece of sodium dropped into water, you would remember it. The violent reaction breaks the bonds between the hydrogen atoms and the oxygen atom in the water molecule. Enough heat will be given off that the newly formed hydrogen gas explodes.

Some elements may be toxic like the gas chlorine. Like sodium, it’s too reactive to occur on its own in nature. When it is isolated, it is a yellow-greenish gas that is heavier than air. It smells a lot like bleach because it is just one of the elements that creates bleach. If you breathe in chlorine gas, you will feel like you’re choking and it can cause damage to your respiratory tract and lungs which is why it has been used as a chemical weapon.

But when sodium and chlorine join together into one substance, they become something necessary for life. Something we need every day to keep our hearts beating. They become sodium chloride – or salt.

Chemistry happens around us all the time. It is the change from rubbery dough to fluffy bread when heat is applied. It is how shampoo gets sudsy when you scrub it into your hair. It is why metals rust, or they don’t. Chemistry isn’t a secret or some sort of dark magic. It’s the explanation for everything that occurs around you and inside you – your heart pumping, or hurting.

Chemists study the composition, structure, properties, and relationships formed between substances, and how these substances can change. Reactions that are measurable. Changes that can be quantified. Attraction or the way elements and atoms bond. Why some bonds are hard to break apart and why others disintegrate, dissolve or separate easily. Chemistry is the understanding of matter.

Or maybe, it’s the understanding of things that matter. Relationships. Emotions. Attraction. Hearts racing. Body temperature rising. Stomach churning. It’s the properties of love and how it can change.

But love can’t be measured with a litmus test.
