Smartphone. Scientific experiments with a smartphone

The smartphone became our regular companion and simplified the solution of many everyday problems. However, few people know that this useful gadget can serve as a mini-laboratory that will allow anyone to plunge into the world of science.
Ulysses Delibr talks in detail about which sensors are built into the smartphone and how this can be useful to the researcher. And then he invites readers to conduct a number of fascinating experiments, among which:
- measuring the mass of the Earth,
- determination of the radius of the Earth using a pendulum,
- verification of the law of preservation of mechanical energy,
- analysis- analysis The sound of a musical instrument,
- observation of infrared radiation,
- measuring the thickness of the hair,
- the study of plant cells and other micro-objects,
- the search for planets outside the solar system.
The proposed experiments will not require long preparation and complex equipment - any fan of science and technology can be carried out!
