“Here’s a throwback Thursday thing for ya! Enjoy some art inspired by Physics Fiasco! That’s story 2 in the Journey To Excelsior story collection.”
“The plot is that I meet my awesome physics teacher for the first time…and I think he’s actually an alien who raised my intelligence for an alien experiment.”
Magnetic
‘Moony, what’s this?’ Remus looks away from the pan on the stove and sees Sirius staring quizzically at his fridge.
‘It’s a magnet,’ he explains easily. ‘Mum gave it to me.’
‘So it’s a Muggle thing? How does it stay up?’ Sirius’s voice gets louder and he tentatively pulls at the magnet, flinching slightly when it comes off. ‘Oh my God, I’m sorry!’
‘Calm down.’ Remus shuts him up and lowers the heat of the stove before walking over and taking the magnet from Sirius’ hands, putting it back in place. ‘It sticks back up. See?’
Sirius’ eyes almost glimmer, a relieved look on his face. ‘That’s brilliant! How does it work?’
‘Every substance is made of tiny units called atoms, every atom has even tinier particles that spin around and generate an electric current.’ Remus explains while walking back to the stove, Sirius behind him and a fond smile on his face as he remembers the days his mother would be the one explaining the workings of the world to him. His mother was smart. ‘Usually these particles spin in opposite directions and cancel each other out, but for things such as magnets a lot of them spin in the same direction and cause attraction to other materials in which the particles are spinning the other way. Opposite magnets attract each other, because they seek balance.’
He can feel Sirius’ arms sneak around his waist and Sirius’ chin resting on his shoulder.
‘Aw! That’s just like us!’

Face masks use capillary action
I wondered how the clay face mask I was wearing worked, why it was worth my time. Clay can absorb many times it’s own mass in liquids via capillary action (or capillary motion, or capillarity, or wicking). This falls under the laws of continuum mechanics, a subset of classical mechanics, which treats substances as a continuum rather than discrete particles.
Capillary action allows a substances to act independently and even against external forces, and to flow into narrow spaces propelled by surface tension and adhesive forces.
The clay absorbs excess sebum from the skin it comes into contact with using capillary action. Capillary action itself is not that surprising a mechanism here. But, the relative malleability of the mask allows the clay to come into contact with more surface area of the skin than say a blotting paper used for the same purpose.
Future rabbit holes: fluid vs liquid; laws and mechanics classes in physics; math and physics (a continuum operates outside of a coordinate system, lots of interesting math there to explore in terms of geometry as well as force calculations); wtf is skin care and how to active ingredients work?

Could anyone explain Einstein's theory of Relativity in really really basic no-physics-background language
Sort of a "Physics for Dummies" look at the force of gravity. What makes it so "weak" when we obviously feel its powerful effects every day? Doesn't gravity dominate the universe?
Physics musings on the force of gravity, and how to better understand it as a layman.
Guilty as Charged: I Had an Ulterior Motive
Okay, I admit it. I had an ulterior motive when I wrote the Star Trails Tetralogy. I don’t think it was a bad one, but it was there nonetheless. As I’ve mentioned before, perhaps ad nauseam, I was inspired to pursue a career in a technical field by the science fiction I read as a kid. And that is what I wanted to do with my stories, make science intriguing and interesting enough that my readers…
