Microclimate change
A CO2 detective story in my flat
I love my new flat, but I'm getting headaches. There's not a lot of ventilation and I have a sense that just my breathing might be enough to alter my …
Rising tides
The future if ice caps melt
We explore the realities of melting ice caps—examining how sea levels might rise and the implications for our world. Is this a critical juncture for …

Let's make rainbows 🌈
Creating digital rainbows with GPT4
I saw the most spectacular rainbow not long ago and wondered whether I could simulate it 🤔. I decided that, with the help of GPT, it would be totally doable and …
Constrained particles
My first physics collaboration with GPT4
GPT and I built a interactive particle simulation with constraints - each particle must stay equidistant from two other particles. It took just a few hours to …
Rubbish reality
Unmasking our landfill legacy
So, picture a landfill. It's essentially a gaping hole that swallows our waste, an insatiable beast. But exactly how insatiable is it? How gigantic are these …

Grow your own food?
Unearthing the truth with guesstimation
Have you ever daydreamed about leading a self-sufficient life, growing all your food on a patch of land? It's an alluring fantasy, isn't it? But how feasible is …
Pickle power
Unblocking guesstimation gridlock with the geometric mean
Picture this – you're in a bustling city, London, to be precise, with a pickle in hand 🥒. Now imagine every pickle consumed in London over the span of a year, …

Staggering scales
Guesstimating the number of atoms on earth
And, we get to add another tool to our toolbox today - scientific notation. It might sound a little complicated if you're new to it, but trust me, you'll soon …
Guesstimating the earth
A journey to the center of our planet
Today is all about doing your first guesstimate. We'll do it by embarking on a cool thought experiment together – trying to estimate the distance to the centre …
What is guesstimation?
The process of solving "impossible" problems
In this series, I'll show you how not to stress about big, impossible sounding problems, like "how many people are picking their nose right now?". The secret is …

Particle in a box 📦
How do quantum particles move
This collection of tutorials is dedicated to exploring the quantum behaviour of particles moving under the influence of a confining potential - a "quantum box". …
Two state quantum systems
A model for solid state nuclear reactions
The Project Ida team and I have created a series of computational tutorials in the form of Python-based Jupyter notebooks on two state quantum systems. Nobel …
Nuclear resonance energy transfer
A Marie Curie fellowship proposal
The process of applying for EU money is (as with many grant applications) very involved. It does however, provide a good opportunity to condense your thoughts …
Deuterium cold fusion experiments
Prosasic explanation of my 'success'
It's been some months since the Deuterium drama almost put a stop to my cold fusion experiments. Luckily, I was still able to run a couple of experiments in …
Gentle nuclear
Engineering the nucleus
Have you ever thought about a world where nuclear energy doesn't mean radiation and toxic waste? Sounds like a far-fetched idea, right? In the video above, we …
Stern-Gerlach experiment
A classical view
To my surprise, it is only very recently that Stern-Gerlach interferometer experiments are being considered practical enough to implement and yet they are used …
What is cold fusion?
Past, present, future
Imagine a future where households and businesses generate their own clean energy. No more reliance on massive power plants, no more coal, oil, or even solar and …
Plotting Palladium
Using Observable notebooks to aid research
In this post I've embedded an Obvservable notebook that I'm trying out as an easy way to visualise the loading of deutereium into palladium in my experiments. …
Deuterium drama
Unforeseen chemistry challenges in cold fusion
It was all going so well! Alas, I had not factored in some important chemistry that slowly clogged up my deutereium generator over the Christmas break 😫.

The road to deuterium
Next steps in my cold fusion experiments
It's been 3 months since I did my first cold fusion experiment. I've open sourced my research, been on a cold fusion conference, made some new collaborators and …
My first cold fusion experiment
It's been a long time coming
Yesterday I did my first cold fusion experiment. I've been working up to this since 2017. Needless to say I was incredibly excited. Did I make cold fusion …
Coconut conundrum
Pivoting my cold fusion experiments
If you've been following me @CasualPhysics on Twitter, then you will have seen the rather large spanner in the works for my Les Case replication experiments.

Walking droplets
Quantum behaviour from a classical system?
What's really interesting about these fluid dynamics experiments is that they appear to produce similar behaviour as seen in quantum mechanics 🤯. This result …

Becoming an experimentalist
My foray into cold fusion experiments
A month ago, I committed myself to making some local cold fusion connections by placing somewhat cryptic posters in London university physics departments. One …
Research rabbit hole
Delving deeper into cold fusion (LENR)
I'm very grateful to cold fusion veteran Prof. Peter Hagelstein - he's pointed me in the direction of the right rabbit hole in which I'm now learning a lot. He …
Cold fusion
A very brief history
As with many people, cold fusion was thrust into my awareness in 2011 when Andrea Rossi claimed to have demonstrated cold fusion using nickel and hydrogen. …

Plasma art
Sparking curiosity in science
The walls of physics departments are often lined with poster contributions from old conferences. The vast majority go without so much as a glance from visitors …
Instabilities in fusion plasmas
A summary of my academic research
To reach extreme fusion temperatures, energetic beams of particles are injected. Once the plasma “ignites”, energetic fusion products should heat the plasma in …
Fusor: Star mode
Understanding if enhanced electrostatic fusion is possible
One of the original concepts for a fusion reactor involved the use of electric fields from spherical charged wire grids - something now known as a Fusor.
Play with particles
An experiment in cross platform physics apps
Inspired by advances in both web and mobile technologies, I created the Play with Particles webapp. The user is able to control the motion of particles through …
