Individuality and Impression, How We Remember People

We remember people by multiple signs and signals.

To know someone, it is not only from the person’s apperance, but also many other elements that relate to this very individual. This is what we called, individuality.

Though most of the time someone remembers a person by his/her face, the overall appearance.

However, when you pick up the phone, the voice from the other side let you know instantly who this person is if the caller is one of your friends. ...READ MORE

The Famous Train Example of Relativity

The famous example of relativity by Einstein was the moving train problem.

When one man stand before a fast moving train, and two lightening strikes, he’ll see the two lightening strikes appear at the same time.

However, if the man stands on the train as the train is moving from left to right, he’ll see the the two lightening strikes appear at different time, as the right lightening strike appears first and the left lightening strike appears later. ...READ MORE

Hoax

Suppose your senses are lying to you, which makes all of your perceptions none other than illusions.

If I am, in a simulation machine, which all of my senses are artificially simulated, the senses are so real I can’t tell whether I am in a simulation machine.

If I am indeed in a simulation machine, how come I never wake up once to know the real world? The hypothesis is that I live inside a simulation machine, the opposition is that I never wake up to know I live inside a simulation machine. ...READ MORE

The Modern Science

The modern subjects of science have quite a limited time of development.

Not until just a century ago, we have made substantial chemical and physical progresses.

20th century is truly a remarkable age, where scientists and theories flourished, whilst wars and conflicts went on rampaging.

We have just made some very recent discoveries.

However, all of these theories are new, and they are constantly being disproved. ...READ MORE

What Is Radioactive?

Radiation, nuclear weapons or X-rays. Common terms we find in our life, however, do we know what exactly they are?

Radioactivity.

When we call a substance radioactive, it is because the substance is constantly emitting particles. In the Periodic Table, any atomic number that is bigger than 83 (including 83, bismuth) is a radioactive element.

Before get into this, let’s first understand what an atom actually does in a radioactive scenario. ...READ MORE

Non-Newtonian Fluids on a Particle Level

Recently I found this new concept–Non-Newtonian Fluids. Many people have tried out and played with this kind of “new” matter inside their houses or shot videos about it.

I remember that I saw some military videos about putting this kind of tech onto bullet-proof vests 4 or 5 years ago. Yeah at the time I thought it was a tech.

However, this physics phenomenon exists since the Genesis. ...READ MORE
