Explain how the development of the atomic theory is an example of science's self-correcting process of discovery in depth.
Stolb23 [73]

Answer:

En química y física, la teoría atómica es una teoría científica sobre la naturaleza de la materia que sostiene que está compuesta de unidades discretas llamadas átomos. Empezó como concepto filosófico en la Antigua Grecia y logró ampliar aceptación científica a principios del siglo XIX cuando los descubrimientos en el campo de la química demostraron que la materia realmente se comportaba como si estuviese hecha de átomos.

La palabra átomo proviene del adjetivo en griego antiguo átomos, que significa «indivisible». Los químicos del siglo XIX empezaron a utilizar el término en relación con el número creciente de elementos químicos irreducibles.1​ Cerca del cambio al siguiente siglo, a través de varios experimentos con electromagnetismo y radiactividad, los físicos descubrieron que los "átomos indivisibles" eran de hecho un conglomerado de varias partículas subatómicas (principalmente, electrones, protones y neutrones), las que pueden existir separadas unas de otras. De hecho, en ciertos entornos extremos, como las estrellas de neutrones, la presión y la temperatura extremas impiden que los átomos puedan existir en absoluto.

Ya que se descubrió que los átomos podían dividirse, los físicos inventaron el término «partículas elementales» para describir las partes "indivisibles", aunque no indestructibles, de un átomo. El campo de ciencia que estudia las partículas subatómicas es la física de partículas y es en este campo donde los físicos esperan descubrir la auténtica naturaleza fundamental de la materia

What is a control used for in an experiment?
Setler79 [48]
The control is what you keep the same for each one. For example if you are doing an experiment with plants say you water one with lemon juice, one with milk and one with warm water. The control would be they all have the same amount of sun light and soil. So the growing is equal to keep the experiment fair.
