GR analysis of Cavendish experiment
In GR the gravitational force is a fictitious force. Fictitious forces cannot actually be measured, only inferred from the motion with respect to the chosen reference frame.

So, what does the Cavendish experiment measure? To be clear, I know that it is the torsion in the string, but what GR...

Hello from an A-Level Physics Student
Hi everyone!


I’m an A-Level physics student preparing for my exams and spending a lot of my free time exploring classical mechanics and fluid dynamics.


Recently, I’ve been working through a conceptual model using Total Internal Reflection (TIR) and bathymetric trench geometry to passively...

Conceptual Model: Tsunami Wave Energy Deflection via Bathymetric Total
Hi everyone,


I have been working on a theoretical model that uses the acoustic-gravity wave analogue of Total Internal Reflection (TIR) to deflect shallow-water wave energy away from coastlines using engineered seabed trenches.





I wanted to share my derivations and geometric...
