What is the most beautiful experiment?

“The Meselson-Stahl experiment has been called the most beautiful experiment in biology for the elegant logic of its deceptively simple design,” says Judith Campbell, Caltech professor of chemistry and biology. At the time, there were three leading theories for how DNA copies itself into new cells: 1.

What is a simple experiment?

A simple experiment is one researchers often use to determine if changes in one variable might lead to changes in another variable—in other words, to establish cause-and-effect.

What is a simple experiment example?

Usually, a simple experiment answers a “What would happen if…?” cause-and-effect type of question. Example: You wonder whether a plant grows better if you mist it with water. You get a sense of how the plant is growing without being misted and then compare this with growth after you start misting it.

Is physics easy or hard?

Students and researchers alike have long understood that physics is challenging. But only now have scientists managed to prove it. It turns out that one of the most common goals in physics—finding an equation that describes how a system changes over time—is defined as “hard” by computer theory.

How do you start liking in physics?

Instead of memorizing formulas, it is better to understand the derivations. Mugging up a number of formulas will only make you more apprehensive of the subject. Rather, if you try and understand where they come from, you will start enjoying physics and its applications!
