Scientists test their hypothesis (假设) either through experiments or fieldwork and the process is filled with changes.Carry out experiments1.. You make a simpler-scale or smaller-scale version of the part of the real world you want to study. In an experiment, a scientist tries to look at...
It was during the COVID-19 pandemic that sociologist Brandon Vaidyanathan and colleagues at The Catholic University of America set out to test a hypothesis: that the frequency of aesthetic experiences in scientific work is associated with flourishing and eudaimonia — finding motivation and meaning in...

like climbing a set of stairs with no little steps in between. The spacing between these levels depends on the mass of the electrons and the strength of the magnetic field, so as the magnetic field increases, the energy levels of the electrons should increase by set amounts based entir...
Scientists study the natural world by using "scientific method". When a scientist observes some phenomenon in nature, he develops an idea, called a theory or hypothesis(假设), about what is happening. Then he does an experiment to test his theory. If the results are as expected, then the ...
Each project followed the steps of the scientific method, teaching students’ essential skills in observation, hypothesis formation, and conclusion drawing. They started by brainstorming questions that sparked their interest. Aft...
Megalodon’s teethresemble those of a modern great white shark, so some scientists previously concluded that the two sharks had a similar stout body shape. Shimada followed this hypothesis when he published a paper inSeptember 2019, arguing that the maximum size for megalodon was “just” 50 fee...
Ideally scientists make observations, formulate hypotheses (假设), and test those hypotheses by making further observations. When there is difference between what is observed and what is predicted by the hypothesis, the hypothesis is revised. Science proceeds in this way, which is a gradual method ...
