Buy me a coffee?
Writing this blog is a labour of love, and one which I evidently need a little encouragement towards on occasion. If you like what I write, the best way to show your gratitude would be to fuel my caffeine addiction and buy me a coffee to say thank you. All coffee donations are gratefully accepted!

Astrotropes: Wormholes
Wormholes show up a lot in fiction, don’t they? I’ve seen the concept reiterated several times in various different ways, in everything from obscure sci fi novels to high budget movies. Which makes sense really, because it’s a compelling idea, … Continue reading

Energy!
Inspired by that last Astrotropes post of mine, here is a very circular graphic showing kinetic energies of various things, fictional and non-fictional. Go and check the other post for some more details, and mind out for any spoilers. (click … Continue reading
Quark Fusion
When thinking about the future of energy production, aside from renewable energy like solar power, fusion is something which immediately springs to mind. Clean, efficient, and the same thing which stars have been using for around 13 billion years. But … Continue reading

Planning a trip to Titan but not sure how much fuel you’ll need? Worry not! Here’s a convenient map showing the required delta-v to get from place to place in the solar system! Delta-v is shorthand meaning change in velocity … Continue reading
The Song of The Dunes
I’m really quite fascinated by singing sand dunes. Also known variously as whistling sand or booming dunes, this is a phenomenon observed in places across the world when the right set of circumstances cause sand to be a little noisier than usual. … Continue reading
Bohemian Gravity
This video made me giggle with glee! If you’re a fan of string theory and classic rock (and let’s face it, who isn’t?) then you’ll probably find this as wonderfully geeky as I do. A cut-down explanation of string theory … Continue reading
Ablaze
The Sun is doing some quite exciting things at the moment. Just the other day, it spat out a X1.7 flare, the first X-class flare this year. Things are likely to stay interesting for a while now too. We’re very … Continue reading
Rainbow string
Anyone who knows me will know that I just love that intersection where science and art meet. And things like this are precisely why! Paul Friedlander, one of those delightful rare individuals who’s both a physicist and an artist, put … Continue reading
