All quotes about death

34
Little fly, thy summer’s play
My careless hand hath brushed away.
Am not I a fly like thee,
Or art not thou a man like me.
For I dance, and drink, and sing
Till some blind hand doth brush my wing.
If that is life, and strength, and breath
And the word of thought is death
Then am I a happy fly?
If I live, or if I die.
William Blake
45
Sleep is a death, O make me try
By sleeping, what it is to die,
And as gently lay my head
On my grave, as now my bed.
Sir Thomas Browne
Religio Medici, part II
48
I love thee with the love I seemed to lose
With my lost saints,—I love thee with the breath
Smiles, tears, of all my life!—and, if God choose,
I shall but love thee better after death.
Elizabeth Barrett Browning
Sonnets from the Portuguese
132
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death.
Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
William Shakespeare
Macbeth, V. i. 19.

Half a league onward,
All in the valley of Death

Because I could not stop for Death,
He kindly stopped for me,
The carriage held but just ourselves
And Immortality.

Death comes with a crawl, or comes with a pounce,
And whether he’s slow or spry,
It isn’t the fact that you’re dead that counts,
But only, how did you die?

How Did You Die?

The prison seemed to fill,
For the Lord of Death with icy breath
Had entered in to kill.

No cold gradations of decay,
Death broke at once the vital chain,
And freed his soul the nearest way.

963
O death! I know it—’tis my famulus—
Thus turns to naught my fairest bliss!
That visions in abundance such as this
Must be disturbed by that dry prowler thus!
Johann Wolfgang von Goethe
Faust
1092
For the crown of our life as it closes
Is darkness, the fruit there of dust;
No thorns go as deep as the rose’s,
And love is more cruel than lust.
Time turns the old days to derision,
Our loves into corpses or wives;
And marriage and death and division
Make barren our lives.
Algernon Charles Swinburne
Dolores

Though they go mad they shall be sane.
Though they sink through the sea, they shall rise again.
Though lovers be lost, love shall not,
And death shall have no dominion.
Dylan Thomas

My life is light, waiting for the death wind,
Like a feather on the back of my hand.
T.S. Eliot

Death be not proud, though some have called thee
Mighty and dreadful, for, thou art not so,
For, those, whom thou think’st, thou dost overthrow,
Die not, poor death, nor yet canst thou kill me.
John Donne
Holy Sonnets X
1142
Don’t strew me with roses after I’m dead.
When Death claims the light of my brow
No flowers of life will cheer me: instead
You may give me my roses now!
Thomas F. Healey

Suffer me to take your hand.
Suffer me to cherish you
Till the dawn is in the sky.
Whether I be false or true,
Death comes in a day or two.

Mariposa
1311
Show me a love was done and through,
Tell me a kiss escaped its debt!
Son, to your death you’ll pay your due—
Women and elephants never forget.
Dorothy Parker
Ballade of Unfortunate Mammals
1319
Oh, it is sure as it is sad
That any lad is every lad,
And what’s a girl, to dare impore
Her dear be hers forevermore?
Though he be tried and he be bold,
And swearing death should he be cold,
He’ll run the path the others went....
But you, my sweet, are different.
Dorothy Parker
Incurable
1446
In every parting there is an image of death.
George Eliot
1472
For the Angel of Death spread his wings on the blast,
And breathed in the face of the foe as he pass’d;
And the eyes of the sleepers wax’d deadly and chill,
And their hearts but once heaved, and for ever grew still!
Lord Byron
The Destruction of Sennacherib
1476
To die, to sleep—
To sleep, perchance to dream, ay there’s the rub,
For in that sleep of death what dreams may come
When we have shuffled off this mortal coil,
Must give us pause; there’s the respect
That makes calamity of so long life.
William Shakespeare
Hamlet
1485
The harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly; it is dearness only that gives everything its value. I love the man that can smile in trouble, that can gather strength from distress and grow brave by reflection. ’Tis the business of little minds to shrink; but he whose heart is firm, and whose conscience approves his conduct, will pursue his principles unto death.
Thomas Paine
1596
I do not want to believe that death is the gateway to another life. For me, it is a closed door. I do not say it is a step we must all take, but that it is a horrible and dirty adventure.
Albert Camus
1672
Life is short. But death is very, very long.
Henning Mankell

Comparing classifier performance with baselines

Sat 23-03-2024

All animals are equal, but some animals are more equal than others. —George Orwell

This month, we will illustrate the importance of establishing a baseline performance level.

Baselines are typically generated independently for each dataset using very simple models. Their role is to set the minimum level of acceptable performance and help with comparing relative improvements in performance of other models.

Unfortunately, baselines are often overlooked and, in the presence of a class imbalance5, must be established with care.

How Analyzing Cosmic Nothing Might Explain Everything

Thu 18-01-2024

Huge empty areas of the universe called voids could help solve the greatest mysteries in the cosmos.

My graphic accompanying How Analyzing Cosmic Nothing Might Explain Everything in the January 2024 issue of Scientific American depicts the entire Universe in a two-page spread — full of nothing.

How Analyzing Cosmic Nothing Might Explain Everything. Text by Michael Lemonick (editor), art direction by Jen Christiansen (Senior Graphics Editor), source: SDSS

The graphic uses the latest data from SDSS 12 and is an update to my Superclusters and Voids poster.

Michael Lemonick (editor) explains on the graphic:

“Regions of relatively empty space called cosmic voids are everywhere in the universe, and scientists believe studying their size, shape and spread across the cosmos could help them understand dark matter, dark energy and other big mysteries.

To use voids in this way, astronomers must map these regions in detail—a project that is just beginning.

Shown here are voids discovered by the Sloan Digital Sky Survey (SDSS), along with a selection of 16 previously named voids. Scientists expect voids to be evenly distributed throughout space—the lack of voids in some regions on the globe simply reflects SDSS’s sky coverage.”

Error in predictor variables

Tue 02-01-2024

It is the mark of an educated mind to rest satisfied with the degree of precision that the nature of the subject admits and not to seek exactness where only an approximation is possible. —Aristotle

In regression, the predictors are (typically) assumed to have known values that are measured without error.

Practically, however, predictors are often measured with error. This has a profound (but predictable) effect on the estimates of relationships among variables – the so-called “error in variables” problem.

Martin Krzywinski @MKrzywinski mkweb.bcgsc.ca
Nature Methods Points of Significance column: Error in predictor variables. (read)

Error in measuring the predictors is often ignored. In this column, we discuss when ignoring this error is harmless and when it can lead to large bias that can leads us to miss important effects.
