Sound effects, gps navigation & water reflections

Commanding world functions, from a computer

Computers, mobile phones, tablets and other hand-held electronic devices, nuclear power-plants, GPS satellites all owe their existence to revolution in Physics that took part between 1800 and 1900. Before then, classic physics was used to describe the world around us, but it was not able to explain some phenomena such as the Photoelectric effect, which regulates solar panel digital cameras and remote controls, or the Michelson-Morley experiment, which confirmed the theory of relativity and precise positioning measurements at the base of a GPS. Without these experiments, none of our current technologies would exist.

Our Physics course will allow students to carry out remotely physical experiments using real instruments, control measurement parameters and then get real data, all from home or anywhere with an internet connection. Students running the experiment will set up parameters and give predefined commands to trigger experimental tasks. At the same time, other users will observe the experiment via laboratory webcams and exchange remarks, discuss results by chat and social media.

Our Physics course will contain selected seven experiments from this list:
  • Shielding nuclear reactors with Gamma radiation attenuation
  • Use of the photoeletrical effect in solar panel digital cameras and remote control systems
  • Confirming the theory of relativity with the Michelson-Morley experiment measuring the position or distance from a location with the Michelson Interferometer
  • Quantum mechanics, finally created by Max Planck and its study of black body radiation
  • How the Rutherford experiment lead to the discovery of protons and neutrons
  • How to diffract of X rays, uncovering the specific crystal structure of many materials, at the base of the most common diagnostic tools in medicine
  • How to define the relation between a current and a voltage drop on the resistor with the Ohm law.
  • The Doppler effect, i.e. an apparent shift in frequency for a sound wave produced by a moving source.
  • Why does a diamond shine so much? Why do our legs look shorter when we stand in the water? This is regulated by Snell’s law, also known as law of refraction, which determines how a ray of light is reflected across two media, such as air and water, for example
  • The SellHertz experiment, which discovered how to produce and receive radio waves, leading to the creation of the radio.
These and many more notions and experiments will give our students a better understanding of how physics regulates both nature and technology, and introduce them to potential working fields that are not only in the science world, but where knowledge of physics is still required.
