Quantum mechanics, it is in everyday life!

 Quantum mechanics, it is in everyday life!

Water boils when heated (infrared).
Heat is longer wavelength than visible lights.
Visible lights are longer wavelength than X-rays.
Wavelength: X-ray < Visible lights < Heat (infrared)
Water is transparent.
Transparent means interaction between visible lights and water is minimum.
Thus, visible lights don’t effectively boil the water because interaction is minimum.
But they interact with the molecules in human eyes.
To see objects, we need visible lights.
To boil the water, we need infrared.
==> Quantum mechanics is theories of lights and their interaction with given materials.

The difference between learning and studying

  The difference between learning and studying ﾠ Learning is possible only if there is something to learn (knowledge that already exist). Learning is possible only if there is someone who can teach you. Learning is possible only if someone has found something new or created new knowledge. ﾠ The people who focus on learning are: ﾠ 1. Moving towards a passive life. 2. You wouldn't know what to do unless you learned what to do by reading a book or being taught. 3. You would be frustrated if you don't have an answer unless someone gives you the answer. ﾠ Because of these, if you enjoy learning new things or knowledge, you might enjoy the learning but you will be mentally enslaved by the people with more knowledge or (and) political or (and) economic power gradually.   ﾠ ============================ Studying is a process of discovering new things or finding answers oneself. When you encounter something that you didn't know (or didn't expect), you can find answers by studying

Students shouldn’t plagiarize, really?

  Students shouldn’t plagiarize, really?   Educators say that they teach students to be leaders. Educators claim that students have to learn to critical and creative thinking to be leaders. For these, educators ask students not to copy and paste because it is not creative. They also say that plagiarism is serious issues.   Yet, educators use publisher-prepared or other exam banks to prepare exams and quizzes.   Instead of creating their own exams and quizzes, they copy and paste from other sources including textbooks. Since institutes pay for the services and textbooks, it might not be a crime.   But it is still copy-paste.   Could educators who are not able to create their own exams and quizzes teach students to be leaders? The chances would be very close to ‘NONE’. Still, they claim that they teach students to be leaders. f you are a student and see an educator uses exams and quizzes that can be found online or other sources, you should request them ‘N
