What did Eugen Goldstein discover?

A:

Quick Answer

Eugen Golstein discovered many important things in science, including anode rays and the proton. After discovering anode rays, which are streams of ions that are produced from specific gas discharge tubes, Goldstein worked with many different gases, including hydrogen.

Full Answer

There is some confusion as to whether Goldstein identified that hydrogen ions were protons because the mass to charge measurements that identified protons were not made until later by Wilhelm Wien.

The proton is one of three atomic particles that all atoms can contain, along with electrons and neutrons. A single proton contains a positive charge of 1. Protons are important in fields of science, in particular chemistry and physics, that try to understand how particles interact.

  • Q:

    Why is physics the most basic science?

    A:

    Physics is the most basic science because it is the science of matter, energy and their interactions. Every other hard science, such as biology and chemistry, is merely a study of a subset of physics' general purview since both biology and chemistry are ultimately the study of certain types of matter, energy and their interactions. Nonetheless, other sciences contain enough specialized information that practically speaking, they are separate.

  • Q:

    Why are theories never proven?

    A:

    Proofs of theories are limited to the self-contained systems of analytical logic and mathematics, while science explains nature as a dynamic whole. Proofs are final and binary - two features that cannot exist in something as living and changing as science. Also, theories can be falsified when new evidence is discovered.

    What is speed in science?

    A:

    In science, speed is defined as the total distance traveled divided by the total time it took to travel that particular distance. Speed is dependent on the amount of time that it takes a person or object to move toward something.
