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...

Why online classes are not as effective as face to face?

Why online classes are not as effective as face to face? One of the participants asked a question in the teaching professors virtual conference ongoing now. The question was that how to make online teaching effective. From the conference, there is limited info about online teaching. I replied. If teaching is focused on delivering knowledge by understanding, effectiveness would drop significantly for online. This is because learning knowledge by understanding doesn’t require thinking. When thinking is not involved, it is like training a dog. Dogs can understand human signals and words and follow instruction once trained. The problem is that you cannot train dogs online.  I continued. To make either online or face to face teaching effective, thinking function of the human brain has to be tackled. And the thinking process includes data collection, analysis, prediction and decision making. The person replied. How to teach students to learn knowledge and thinkin...

Something you should to know about learning knowledge by understanding!

1. Learning knowledge by understanding will train you to be a slave. You have to beg for knowledge from the knowledgeable person like a teacher or a professor). 2 Learning knowledge by understanding will hold you in the past. Knowledge is something that is already known. Even if you learned new one, it was already known by someone somewhere in the world. 3. Learning knowledge by understanding will block your brain from thinking. Once you understand and know, your brain will stop. 4. Learning knowledge will stress your brain. Once you learned, your brain stops thinking. To learn new knowledge, you will need to restart your brain. Basically, you are repeating stopping and going as driving in traffic jam. 5. Learning knowledge by understanding will stress your life. As your brain stressed, your life will be stressed. 6. Learning knowledge by understanding is common learning methods for animals with brain. Dogs can understand human once they are trained. Dogs can do ...
