## Philosophy and religion

### Confucious

> We have two lives, and the second begins when we realize we only have one.

> By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.

> If you make a mistake and do not correct it, this is called a mistake.

> Real knowledge is to know the extent of one's ignorance.

### Aristotle

> No great mind has ever existed without a touch of madness.

> It is the mark of an educated mind to be able to entertain a thought without accepting it.

### Friedrich Nietzsche

> He who has a why to live for can bear almost any how.

> He who fights with monsters should look to it that he himself does not become a monster . . . when you gaze long into the abyss the abyss also gazes into you.

> And those who were seen dancing were thought to be insane by those who could not hear the music.

> I'm not upset that you lied to me, I'm upset that from now on I can't believe you.

> The thought of suicide is a great consolation: by means of it one gets through many a dark night.

### Blaise Pascal

> All of humanity's problems stem from man's inability to sit quietly in a room alone.

> If I had more time, I would have written a shorter letter. [[\*](https://knowyourmeme.com/memes/if-i-had-more-time-i-would-have-written-a-shorter-letter)]

### Misc

> Je n'avais pas besoin de cette hypothèse-là. (I had no need of that hypothesis.) - **[Pierre-Simon Laplace](https://en.wikipedia.org/wiki/Pierre-Simon_Laplace#I_had_no_need_of_that_hypothesis)**

> Death does not concern us, because as long as we exist, death is not here. And when it does come, we no longer exist. - **Epicurus**

> Religion is regarded by the common people as true, by the wise as false, and by rulers as useful. - **Seneca**

> The best is the enemy of good. - **Voltaire**

> Receive with simplicity everything that happens to you. - **Rashi**

> I am sitting with a philosopher in the garden; he says again and again 'I know that that’s a tree', pointing to a tree that is near us. Someone else arrives and hears this, and I tell him: 'This fellow isn’t insane. We are only doing philosophy. - **Ludwig Wittgenstein**

## Science

### Carl Sagan

> Somewhere, something incredible is waiting to be known.

> Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.
>
> The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
>
> Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
>
> The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
>
> It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known. [[Pale Blue Dot](<https://en.wikipedia.org/wiki/Pale_Blue_Dot_(book)>)]

### Isaac Asimov

> People who think they know everything are a great annoyance to those of us who do.

> Violence is the last refuge of the incompetent.

> There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge.".

### Arthur C. Clarke

> I don’t believe in astrology; I’m a Sagittarius and we’re skeptical.

> Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.

### Misc

Specialization is for insects. - **Robert A. Heinlein**

> Study hard what interests you the most in the most undisciplined, irreverent and original manner possible. - **Richard Feynman**

> Seek freedom and become captive of your desires. Seek discipline and find your liberty. - **Frank Herbert, Chapterhouse: Dune**

> If I have been able to see further, it was only because I stood on the shoulders of giants. - **Isaac Newton**

Black waves teeming with salt foam to smother this young mouth with pungent slime, to choke ye, engorging your organs til' ye turn blue and bloated with bilge and brine and can scream no more - only when he, crowned in cockle shells with slitherin' tentacle tail and steaming beard take up his fell be-finned arm, his coral-tine trident screeches banshee-like in the tempest and plunges right through yer gullet, bursting ye - a bulging bladder no more, but a blasted bloody film now and nothing for the harpies and the souls of dead sailors to peck and claw and feed upon only to be lapped up and swallowed by the infinite waters of the Dread Emperor himself - forgotten to any man, to any time, forgotten to any god or devil, forgotten even to the sea, for any stuff for part of Winslow, even any scantling of your soul is Winslow no more, but is now itself the sea! - **Thomas Wake, The Lighthouse**

> We don't have to save the world. The world is big enough to look after itself. What we have to be concerned about is whether or not the world we live in will be capable of sustaining us in it.

### Mark Twain

> It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.

> When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to be 21, I was astonished at how much the old man had learned in seven years.

> I do not fear death. I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it.

### Erik Naggum

> Life is hard, and then you die.

> People search for the meaning of life, but this is the easy question: we are born into a world that presents us with many millennia of collected knowledge and information, and all our predecessors ask of us is that we not waste our brief life ignoring the past only to rediscover or reinvent its lessons badly.

> The secret to feeling great about yourself is not to be found in searching for people who are less than you and then show yourself superior to them, but in searching for people who are more than you and then show yourself worthy of their company.

### Charles Bukowski

> The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence.

> For those who believe in God, most of the big questions are answered. But for those of us who can't readily accept the God formula, the big answers don't remain stone-written. We adjust to new conditions and discoveries. We are pliable. Love need not be a command nor faith a dictum. I am my own god. We are here to unlearn the teachings of the church, state, and our educational system. We are here to drink beer. We are here to kill war. We are here to laugh at the odds and live our lives so well that Death will tremble to take us.

> Sometimes you climb out of bed in the morning and you think, I'm not going to make it, but you laugh inside — remembering all the times you've felt that way.

> We're all going to die, all of us, what a circus! That alone should make us love each other but it doesn't. We are terrorized and flattened by trivialities, we are eaten up by nothing.
### Misc

> I've said it before: there are two sorts of atheists. One sort claims that there is no deity, the other claims that there is no evidence that proves the existence of a deity; I belong to the latter group, because if I were to claim that no god exists, I would have to produce evidence to establish that claim, and I cannot. Religious persons have by far the easier position; they say they believe in a deity because that's their preference, and they've read it in a book. That's their right. - **James Randi**

> Here's to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. They're not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do is ignore them. Because they change things. They push the human race forward. And while some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do. - **Rob Siltanen**

> Think deeply about things. Don’t just go along because that’s the way things are or that’s what your friends say. Consider the effects, consider the alternatives, but most importantly, just think. - **Aaron Swartz**

> If you torture the data long enough, it will confess to anything. - Ronald Coase

Quotes


Notes from the book [Secrets of Mental Math - Arthur Benjamin (2006)](https://www.goodreads.com/book/show/83585.Secrets_of_Mental_Math)

## Some quick tricks

### Multiplying by 11:

- 45x11 = (first digit) (sum of the digits) (last digit) = (4) (4+5) (5) = 495
  
  If the sum exceeds 10, carry the 1 to the left:
  - 67x11 = (6) (6+7) (7) = (6) (13) (7) = (6+1) (3) (7) = 737

- Works for larger products as well.
  - 453x11 = 4 (4+5) (5+3) 3 = 4983
  - 681x11 = 6 (14) (9) 1 = 7491

### Multiplying two digit numbers

- If two numbers start with the same digit, and their last digits add up to 10, first multiply the first digit (x) and x+1, and then multiply their last digits, and put them together:
  - 37x33 = (3x4) (7x3) = 1221
  - As a special case, this is very helpful when squaring a 2-digit number ending in 5
    - 65x65 = (6x7) (25) = 4225

### Calculating tips

- To quickly calculate 15% of, say 42:
  1. 10% of 42 = 4.2
  2. 5% = 4.2/2 = 2.1
  3. 15% = 4.2 + 2.1 = 6.3


## Mathemagical tricks

### Psychic math

Ask a person to think of a number (preferably one-digit or two-digit) and ask them to:
1. double it,
2. add 12,
3. divide the total by 2,
4. subtract the original number.

The sequence will always produce the number 6.

The sequence goes like this:
x -> 2x -> 2x+12 -> x+6 -> x+6-x -> 6

### Magic 1089

1. Write down a three-digit number where the digits are decreasing (like 851 or 973),
2. Reverse that number and subtract it from the first number,
3. Take that answer and add it to the reverse of itself.

No matter what the original number is, the sequence will always produce 1089!

Step 1 and 2 are alebraically equivalent to: 100a+10b+c - (100c+10b+a) = 99(a-c) which must be one of the following multiples of 99: 198, 297, 396, 495, 594, 693, 792, or 891, each one of which will produce 1089 after adding it to the reverse of itself.

### Missing digit tricks

Many variations of missing digit tricks can be performed by using the fact that **a number is a multiple of 9 if and only if its digits sum to a multiple of 9**.

For this, you start by forcing a person to come up with a large multiple of 9, asking them to tell you all the digits except one in random order, adding those and subtracting it from the nearest multiple of 9.

For example, ask them to multiply any three-digit number by 1089 (a multiple of 9) from the trick mentioned above. (Say they secretly multiply 1089x573 = 623,997). Ask them to choose a secret digit and call out the rest in any order. (Say they call out, "2...9...3...7...9") Add those to produce 2+9+3+7+9 = 30. The nearest multiple of 9 is 36 which is 6 more than 30. The missing digit must be 6.

If the digits called out add up to a multiple of 9, then there is no way of determining whether the missing digit is 0 or 9. In this case, you merely say, "You didn’t leave out a zero, did you?" If they say yes, you're done. If not, you know the missing digit is nine.

Some subtle ways to force the volunteer to end up with a multiple of 9:

1. randomly choose a six-digit number, scramble its digits, then subtract the smaller six-digit number from the larger one.
2. secretly choose a four-digit number, reverse the digits, then subtract the smaller number from the larger.
3. multiply one-digit numbers randomly until the product is seven digits long. This is not “guaranteed” to produce a multiple of 9, but in practice it will do so at least 90% of the time (the chances are high that the one-digit numbers being multiplied include a 9 or two 3s or two 6s, or a 3 and a 6).

### Rapid cube root of two-digit numbers

This trick relies on the fact that the cubes of single digit whole numbers end in unique digits.

$$
0^3 = 0
$$

$$
1^3 = 1
$$

$$
2^3 = 8
$$

$$
3^3 = 27
$$

$$
4^3 = 64
$$

$$
5^3 = 125
$$

$$
6^3 = 216
$$

$$
7^3 = 343
$$

$$
8^3 = 512
$$

$$
9^3 = 729
$$

Example: Cube root of 474552 (AAABBC) = 78

Steps:

1. Cube just lower than AAA (474) = 343 = 7^3
2. Cube ending in C (2) = 512 = 8^3


### Quick square root of two-digit numbers

Example: Square root of 7921 = 89

1. Look at the numbers preceding the last two digits (79).
2. 79 lies between 8x8=64 and 9x9=81, we know the answer lies in the 80s.
   There are two numbers whose squares ends in 1: 1 and 9. So the answer must be 81 or 89.
3. Compare the original number with the square of 85 (80x90 + 25 = 7225). Since 7921 > 7225, the answer must be 89.

### An amazing sum

Start with a prediction **2247** and three sets of nine numbers each:

- A: 4286 5771 9083 6518 2396 6860 2909 5546 8174
- B: 5792 6881 7547 3299 7187 6557 7097 5288 6548
- C: 2708 5435 6812 7343 1286 5237 6470 8234 5129

1. Choose a random number from each set (say 4286, 5792, and 5435).
2. Take one digit from each four-digit number in order (say 895).
3. Repeat this process three more times with the remaining three numbers, resulting in three more three-digit numbers such as 453, 224, and 675.
4. Add the four numbers to produce 2247, the original prediction.
   ```plaintext
     A B C
     8 9 5
     4 5 3
     2 2 4
   + 6 7 5
   -------
   2 2 4 7
   ```

This trick works because each set of numbers sums to the same total (A -> 20, B -> 23, C -> 17). With person C’s numbers in the right column totaling to 17, you will always put down the 7 and carry the 1. With person B’s numbers totaling to 23, plus the 1, you will always put down the 4 and carry the 2. Finally with person A’s numbers totaling to 20, adding the 2 gives you a total of 2247!
