# 3.6.1 Foresight: prequel

.

Suppose you are an A-Level student. You desire to be a university student.

You should know that

(1997 – 1999; study hard) $\Leftrightarrow$ (1999 – 2002; university student)

.
In 1997, I wanted to be a university student. I could not transform myself to be a university student immediately. I could not travel to 1999, becoming a university student at once. However, I knew that, ideally, if I worked hard (and work smartly) in now (1997), I would be able to enter university. In other words, the event “being a university student in 1999″‘ is equivalent to the event “studying hard in 1997″‘.

I could not control an event in 1999 as it was in my future. But I could control the present-equivalence of the future event.

# Copy Me

Philosopher John Locke published “An Essay Concerning Human Understanding” in 1689, in which he proposed the following criterion for personal identity: if you remember thinking something in the past, then you are the same person as he or she who did the thinking. Later philosophers raised various logical snarls, most of them caused by applying Boolean logic, the prevalent logic system at the time. It has been proposed that modern fuzzy logic can solve those problems, showing that Locke’s basic idea is sound if one treats personal identity as a continuous rather than discrete value.

# 3.6 Now-here-I

David Brower:
Think Globally, Act Locally

.

.
An Anglican bishop:
When I was young and free and my imagination had no limits,
I dreamed of changing the world;
As I grew older and wiser I realized the world would not change.
And I decided to shorten my sights somewhat
and change only my country.
But it too seemed immovable.
As I entered my twilight years, in one last desperate attempt,
I sought to change only my family, those closet to me,
but alas they would have none of it.
And now here I lie on my death bed and realize
(perhaps for the first time)
that if only I’d changed myself first,
then by example I may have in
my family and with their encouragement
and support I may have bettered my country,
and who knows I may changed the world.
.

.
Mahatma Gandhi:
We must be the change we seek in the world.
.

.
(myself: )
Now-here-I philosophy:
Transform all your goals to a single step that you can work on now and here, by yourself.

# Example

.

I sometimes want to be a teacher but think my teaching role can best be by my example — not by class or going to find students.

# 3.5.8 preserve time

.
You can’t preserve time by not using it. When time is not used, time would still pass. You can preserve time only by using it, spending it, investing it, transform it to something much more valuable.

If you know how to preserve time, you do not fear the passage of time. Instead, you love the passage. As time goes, more good works are getting done.

# 當下即是

.

If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those live in present.

–Wittgenstein

.

These quotations induce me to have the following thought:
If you concentrate on a meaningful work now and here, you preserve your infinity. (No explanation here.)

# 3.5.7 palm

To see a world in a grain of sand
And a heaven in a wild
Hold infinity in a palm of your hand
And eternity in an hour

# 3.5.6 have no regrets

… had induced me sometimes to say that if it were left to my choice I should have no objection to go over the same life from its beginning to the end.

# Nobel Prize x 2, part 1

.

The Nobel Prize in Physics in 1956

Bardeen brought only one of his three children to the Nobel Prize ceremony. His two sons were studying at Harvard University, and Bardeen didn’t wanted to disrupt their studies. King Gustav scolded Bardeen because of this, and Bardeen assured the King that the next time he would bring all his children to the ceremony.

.

The Nobel Prize in Physics in 1972

In 1972, John Bardeen shared the Nobel Prize in Physics with Leon Neil Cooper of Brown University and John Robert Schrieffer of the University of Pennsylvania for their jointly developed theory of superconductivity, usually called the BCS-theory.

Bardeen did bring all his children to the Nobel Prize ceremony in Stockholm, Sweden.

# Octupole Expansion

.

I have used a whole month to do this derivation.

.

$V(\mathbf{R}) = ... + \frac{1}{4 \pi \varepsilon_0} \frac{3}{2 |\mathbf R|^4} \sum_{ijk} \hat R_i \hat R_j \hat R_k Q_{ijk} + ...$

.

$Q_{ijk} = \int_{\mathbf r} \left[ \delta_{ij} ( r^2 - 5 r_i r_j + \frac{10}{3} r_i r_j \delta_{jk} ) r_k - |\epsilon_{ijk}| 10 r_i r_j r_k \right] \rho(\mathbf r) d^3 r$

.

But I still do not know whether it is correct or not.

# Job: Pragmatic Idealism

The ideal situation occurs when the things that we regard as beautiful are also regarded by other people as useful.
