An Article from Ribbonfarm by Venkatesh RaoFermi Estimates and Dyson Designs
An Article by Venkatesh RaoA Fermi estimate is a quick-and-dirty solution to an arbitrary scientific or engineering analysis problem. Fermi estimation uses widely known numbers, readily observable phenomenology, basic physics equations, and a bunch of approximation techniques to arrive at rough answers that tend to be correct within an order of magnitude or so. The term is named for Enrico Fermi, who was famously good at this sort of thing.
…It struck me that there is counterpart to this kind of thinking on the synthesis side, where you use similar techniques to arrive at a very rough design for a complex engineered artifact. I call such a design approach Dyson design, after the physicist Freeman Dyson, who was one of the best practitioners of it (not to be confused with inventor James Dyson, whose designs, ironically, are not Dyson designs).
One Tenth of a Second
An Article by Venkatesh RaoThe details are fascinating, but the central argument — that the birth of modernity can be traced to a meta-crisis spawned by the 0.1s problem — is worth understanding and appreciating whether or not you’re a time nerd like me.
There is no convenient leitmotif, comparable to the 0.1s problem, for our contemporary version of the rhyming conditions, but something very similar to the “tenth of a second crisis” is going on today. I suspect our Great Weirding too involves some sort of limiting factor on human cognition that we haven’t yet properly wrapped our minds around. It isn’t reaction time, but something analogous.
Mediocratopia
An Article by Venkatesh RaoI once read a good definition of aptitude. Aptitude is how long it takes you to learn something. The idea is that everybody can learn anything, but if it takes you 200 years, you essentially have no aptitude for it. Useful aptitudes are in the <10 years range.

Meditations
Gravity without affectation
From Sextus: The idea of what it means to live in accordance with nature; gravity without affectation, and a careful regard for the interests of one's friends.
Flesh and a bit of breath
Whatever it is that I am is flesh and a bit of breath.
Any life
Even if you were to live for three thousand years or ten times as long, you should still remember this, that no one loses any life other than the one that he is living, nor does he live any life other than the one that he loses, so the shortest life and the longest amount to the same.
A little thing
Cast everything else aside, then, and hold to these few truths alone; and remember, furthermore, that each of us lives only in the present, this fleeting moment of time, and that the rest of one's life has either has either already been lived or lies in an unknowable future. The space of each person's existence is thus a little thing, and little too is the corner of earth on which it is lived.
Praise has no part in it
Everything that is in any way beautiful is beautiful of itself and complete in itself, and praise has no part in it; for nothing comes to be better or worse for being praised.
Carrying a corpse around
You are a little soul carrying a corpse around.
As Epictetus used to say.
Avenge yourself!
The best way to avenge yourself is not to become as they are.
The clapping of tongues
(for praise from the crowd is simply the clapping of tongues)
Giving up the struggle
How shameful it is that, in this life, when your body does not give up the struggle, your soul should do so first.
Why?
The cucumber is bitter? Then cast it aside. There are brambles in the path? Step out of the way. That will suffice, and you need not ask in addition, "Why did such things ever come into the world?"
Poured
The light of the sun seems to be poured down, and to be poured, indeed, in every direction, but not poured away.
Wanting for nothing
Some day, will you be satisfied and want for nothing, yearning for nothing, and desiring nothing, animate or inanimate, to cater to your pleasures?
Laughter
—and my heart laughed within me.
