# 4.3 Paul Graham

.
LISP writer Paul Graham has wrote an essay called “How to do what you love”, giving some practical advice.

There are three main points, for me, in the essay:
.
.
.
1. Do not feel guilty on not doing some boring jobs.

2. Have a habit to do good work in your current job, whether it is your favourite

3. Always produce in your favourite area, whether it is your current job
.

4.3.1 Do not feel guilty on not doing some boring jobs

Sometime, I faced some boring work. When I wanted to get rid of it, I had a thought: “Someone has to do it anyway. If I do not it, someone else will have to. That means I am wasting other people’s time. I will feel guilty about that.”

Now I do not think in that way. If I choose not to do a job, the number of people for that job will decrease. That means the price to get a person to do the job will rise. Then the person who has chosen that job will get higher salary. So, instead of wasting his time, I make him get a higher salary.

If a job is so boring that it is virtually impossible to get any human being to do it, people will create a machine to get the job done.

Romantic love is a form of love that is often regarded as different from simply sexual love, or lust. Romantic love generally means both an emotional and sexual love, as opposed to Platonic love. There is more emphasis on the emotions than on the bodily pleasures.

Western society has historically emphasized romantic love far more than other cultures in which arranged marriages are the rule. However, the globalization of Western culture has spread Western ideas about love and romance.

Romantic love is the idealization of another person, and of a relationship with that person. Other ideas of love have been advanced by several philosophers and have been popular in different cultures.

Properties of romantic love purported by Western culture that might not appear elsewhere include:

* It must take you by surprise
* It cannot be controlled
* It should be the basis for a lifelong commitment
* It is the highest form of self-fulfillment

e.g. Google had only one function — the search function. It did the very best for the search engine. Once it started to dominate, it expanded its functions, such as Gmail and Google calender, based on its search technology.

It’s best to do one thing really, really well.

Google does search. With one of the world’s largest research groups focused exclusively on solving search problems, we know what we do well, and how we could do it better. … Our dedication to improving search has also allowed us to apply what we’ve learned to new products, including Gmail, Google Desktop, and Google Maps.”

– The biggest cause of trouble in the world today is that the stupid people are so sure about things and the intelligent folks are so full of doubts.

– In view of the stupidity of the majority of the people, a widely held opinion is more likely to be foolish than sensible.

# 2.4.2 Newton, Leibniz, Einstein

.

Newton

Wikipedia: “Two distinct views exist on the meaning of time. One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence. This is the realist view, to which Sir Isaac Newton subscribed, in which time itself is something that can be measured.”

.

Leibniz

Wikipedia: “A contrasting view is that time is part of the fundamental intellectual structure (together with space and number) within which we sequence events, quantify the duration of events and the intervals between them, and compare the motions of objects. In this view, time does not refer to any kind of entity that that objects “move through”, or that is a “container” for events. This view is in the tradition of Gottfried Leibniz and Immanuel Kant, in which time, rather than being an objective thing to be measured, is part of the mental measuring system.”

.

Einstein

Wikipedia: “Many fields avoid the problem of defining time itself by using operational definitions that specify the units of measurement that quantify time. Regularly recurring events and objects with apparent periodic motion have long served as standards for units of time. Examples are the apparent motion of the sun across the sky, the phases of the moon, and the swing of a pendulum.”

2.4 Pure Definition

2.4.1 What is Time

Time is a subtle concept. In this section, we get a proper definition of time. We begin with Newton and Leibniz.

As the creators of Calculus, Newton and Leibniz are famous rivals to each other. On the nature of time, they had completely opposite views. For Newton, time (and space) is the stage for events to happen. Time is something real in itself.

For Leibniz, time is not a real substance. Time is just a bookkeeping system to relate different objects and different events. Time is a system of relations.3

For example, consider the statement “the cloud is higher than the ground.” The cloud is an object. The ground is another object. But “higher than” is not an object. Instead, it is a relation between objects.

Is there anything higher than wisdom? If yes, what is the process to go from wisdom to there?

Dying. (This can be trivial. When you age to certain extent, you die.)

2.1.3 Collections and recollections

2.2 Dispersion
2.2.1 Why is there dispersion

2.3 Statistics

2.3.1 What is statistics

Data Statistics Information Studying Knowledge Aging Wisdom Dying Next What is Next

Data and Information

First, differentiate data and information: Data is raw. Data have no meaning. Information is processed data. Information has meaning. The process to transform data to information is statistics.

Information and Knowledge

Information is higher level than data.

What is higher than information?

Knowledge.
What is the process of transforming information to knowledge?

Studying. (or AI for computers)

If you want a lot of mathematics information, just buy 50 maths books, then you get a lot of information. But if you want a lot of mathematics knowledge, you have a lot of hard work to do.

Knowledge and Wisdom

After knowledge, what is next? Wisdom.

What is the process of transforming knowledge to wisdom?

Aging.
If you want to have a lot of knowledge, buy a lots of books, read them and read them well. But if you want to have a lot of wisdom, you need to live your life for a long time or a long long time.

Wisdom and Next

Is there anything higher than wisdom?

If yes, what is the process to go from wisdom to there?

Dying. (This can be trivial. When you age to certain extent, you die.)

# 2.1.2 Chemical Physics and Physical Chemistry

2.1.2 Chemical Physics and Physical Chemistry

“Chemical physics is a subdiscipline of physics that investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics; it is the branch of physics that studies chemical processes from the point of view of physics. While at the interface of physics and chemistry, chemical physics is distinct from physical chemistry in that it focuses more on the characteristic elements and theories of physics. Meanwhile, physical chemistry studies the physical nature of chemistry. Nonetheless, the distinction between the two fields is vague, and workers often practice in each field during the course of their research.”
