A Bohmian Rhapsody

Mrittunjoy Guha Majumdar talks Bohmian mechanics, the ‘causal interpretation’ of the strange world of quantum mechanics. Fluid droplets bounce when placed on the surface of a vibrating fluidic bath. A student working at the Matter and Complex Systems Laboratory, National Centre for Scientific Research (CNRS) in France discovered this using oil droplets and an oil bath in 2005. The bouncing of the droplets seemed to be guided by an unseen

A Laser Game Controller for the Cambridge Science Festival

James Macdonald describes designing a system to control video games with lasers. Each year over 1000 visitors pass through the main doors of the Institute for Manufacturing for the Cambridge Science Festival; around 300 laser-engineers-of‑the-future make it into the laboratories of the Centre for Industrial Photonics.  Among the many exhibits was the laser video game controller developed by the MRes Ultra Precision CDT (Centre for Doctoral Training) students. In this

In Search of Quantum Gravity

In Search of Quantum Gravity Gianamar Giovannetti-Singh explores the holographic universe Modern fundamental physics consists of two major pillars; general relativity, describing the interactions between matter and spacetime at the largest scales imaginable, and quantum mechanics, the physics governing the behaviour of subatomic particles. Despite each respective theory being tested to an extraordinary degree of accuracy, they are fundamentally incompatible with each other – general relativity predicts continuous spacetime as
