Genius, persistence and good luck have been critical to the great discoveries of modern physics, says Melbourne-based physicist Suzie Sheehy. She investigates the experiments which paved the way for radiation therapy, radio and the internet in The Matter of Everything: Twelve Experiments that Changed the World.

Surprisingly the field of particle physics poses a handful of existential threats, not just for us humans, but for everything alive on Earth – and in some cases, the entire universe. Poking around on the frontier of scientific understanding has its risks.

Michael McInerney, physics experiments with Atari computers    In the 1980s, Michael McInerney was a professor in the physics department at Rose-Hulman Institute of Technology, when he wrote several journal articles about how to control experiments and gather data using Atari computers.    The articles included Interfacing the Atari Microcomputer in the Science Laboratory, which appeared in the spring 1983 issue of Journal of Computers in Mathematics and Science Teaching; Game Port Physics - Introductory Experiments in Linear Dynamics, which appeared in the spring 1984 issue; and Computer-Aided Experiments with the Damped Harmonic Oscillator, which appeared in the October 1985 issue of American Journal of Physics.   This interview took place on May 21, 2018.   "The reviewers refused to believe I could do it which such cheap equipment. ... They said it wasn't possible to do it."   Interfacing the Atari Microcomputer in the Science Laboratory   Game Port Physics - Introductory Experiments in Linear Dynamics   Computer-Aided Experiments with the Damped Harmonic Oscillator   McInerney's bio

In this experiment, a Maxwell‘s Wheel rolls down a rail. A force measurement shows that while the wheel is moving, measured gravitational force of the wheel is slightly smaller compared to it‘s resting state. The explanation for this is the force distribution among the vertical acceleration (which is measurable) and the angular acceleration of the wheel.

In diesem Versuch rollt ein Maiwellrad eine Schiene hinunter. Eine Kraftmessung zeigt, dass während dem Rollen die vom Rad auf die Schiene ausgeübte Gewichtskraft geringer ist als während der Ruhezeit. Der Grund dafür ist die Verteilung der Gewichtskraft auf die senkrechte Beschleunigung, die messbar ist, und auf die Winkelbeschleunigung des Rades.

Blast off with a new contest for Canadian students interested in space and science.

The experimental set up consists of five small vehicles which are coupled by springs. To observe the superposition of oscillations, the pendulum is forced to random oscillation. Using Fourier transformation, it may be seen that this oscillation is a superposition of five frequencies.

A wire is extended at a constant velocity. Occurring forces are measured, so that the Young's modulus can be determined.
