Is the Schrodinger equation second order? In non-relativistic quantum mechanics, we have Schrödinger’s equation, which is first-order. But not every quantum particle is a fermion, and, AFAIK relativistic non-fermion particles obey the Klein-Gordon equation, which is second-order! Is the Schrodinger equation true? Consider the Schrödinger equation, which allows you to compute the “wave function” of […]

Are eggs bad if they float in boiling water? If the egg sinks or stays at the bottom, it is still fresh. An older egg will either stand on its end or float. The float test works because air builds up inside the egg as it ages, and this increases its buoyancy. However, an egg […]

Why is heavy lifting better? Heavy weights increase the power and strength of your muscles without significantly adding bulk or size, especially for women. This means that everyday physical tasks get easier, and consistent training will increase the amount of weight you can lift. You’ll look stronger, too. What is the most effective way to […]

What do groups have in common? Elements in the same group are those that are in a single vertical line from top to bottom. They have the most in common between the two directions. They share the same number of electrons in their valence subshells. As a result, they will all have the same chemical […]

What are the 8 steps in scientific method? That procedure is commonly called the scientific method and consists of the following eight steps: observation, asking a question, gathering information, forming a hypothesis, testing the hypothesis, making conclusions, reporting, and evaluating. How do you design an experiment to test a hypothesis? Experimental design means creating a […]

Can we still recover lost Biodiversities? Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area. How does an ecosystem be able to recover from any disturbances? The major mechanisms of recovery in such ecosystems are primary and secondary succession. […]

Can dog whistles damage human ears? Some sounds (such as gunfire or standing next to a helicopter) are so loud (120-160 dB), that any brief exposure to them without wearing earmuffs or earplugs can damage hearing. (This means that the dog whistles are at a very high frequency but that they do not move the […]
