- Why Wings Work #
But, even as a child, I found that it presented me with a puzzle: how can a plane fly inverted (upside down). When I pressed my 6th grade science teacher on this question, he just got mad, denied that planes could fly inverted and tried to continue his lecture. I was very frustrated and argued until he said, “Shut up, Raskin!” I will relate what happened next later in this essay.
I wish I could send this essay to the 6th grade science teacher who could not take the time to listen to my reasoning. Here’s what happened: he sent me to the principal’s office when I came in the next day with a balsa model plane with dead flat wings. It would fly with either side up depending on how an aluminum foil elevator adjustment was set. I used it to demonstrate that the explanation the class had been given must have been wrong, somehow. The principal, however, was informed that my offense was “flying paper airplanes in class” as though done with disruptive intent. After being warned that I was to improve my behavior, I went to my beloved math teacher who suggested that I go to the library to find out how airplanes fly—only to discover that all the books agreed with my science teacher! It was a shock to realize that my teacher and even the library books could be wrong. And it was a revelation that I could trust my own thinking in the face of such concerted opposition. My playing with model airplanes had led me to take a major step toward intellectual independence—and a spirit of innovation that later led me to create the Macintosh computer project (and other, less-well-known inventions) as an adult.

- The Edge of Forever #
If the cosmos is closed, there’s a strange, haunting, evocative possibility. One of the most exquisite conjectures in science or religion. It’s entirely undemonstrated, it may never be proved, but it’s stirring. Our entire universe, to the farthest galaxy, we are told, is no more than a closed electron, in a far grander universe we can never see. And that universe is only an elementary particle in another still greater universe, and so on, forever. Also, every electron in our universe, it is claimed, is an entire miniature cosmos containing galaxies and stars and life, and electrons. Everyone of those electrons contains a still smaller universe, an infinite regression up and down.
Every human generation has asked about the origin and fate of the cosmos. Ours is the first generation with a real chance of finding some of the answers. One way or another, we are poised at the edge of forever.

- Nature is Speaking #
Nature doesn’t need people. People need nature.
Human beings are part of nature. Nature is not dependent on human beings to exist.
Human beings, on the other hand, are totally dependent on nature to exist.
The growing number of people on the planet and how we live here is going to determine the future of nature. And the future of us.
Nature will go on, no matter what. It will evolve.
The question is, will it be with us or without us?
If nature could talk, it would probably say it doesn’t much matter either way.
We must understand there are aspects of how our planet evolves that are totally out of our control.
But there are things that we can manage, control and do responsibly that will allow us and the planet to evolve together.
We are Conservation International and we need your help. Our movement is dedicated to managing those things we can control. Better.
Country by country.
Business by business.
Human by human.
We are not about us vs. them.
It doesn’t matter if you’re an American, a Canadian or a Papua New Guinean. You don’t even have to be particularly fond of the ocean or have a soft spot for elephants.
This is simply about all of us coming together to do what needs to be done.
Because if we don’t, nature will continue to evolve. Without us.

- Isis #
By Bob Dylan.
I married Isis on the fifth day of May But I could not hold on to her very long So I cut off my hair and I rode straight away For the wild unknown country where I could not go wrong.
I came to a high place of darkness and light The dividing line ran through the center of town I hitched up my pony to a post on the right Went in to a laundry to wash my clothes down.
A man in the corner approached me for a match I knew right away he was not ordinary He said “Are you looking for something easy to catch ?” I said “I got no money”. He said “That ain’t necessary”.
We set out that night for the cold in the North I gave him my blanket he gave me his word I said “Where are we going ?” He said “We’d be back by the fourth” I said “That’s the best new that I’ve ever heard”.
I was thinking about turquoise I was thinking about gold I was thinking about diamonds and the world’s biggest necklace As we rode through the canyons through the devilish cold I was thinking about Isis how she thought I was so reckless.
How she told me that one day we meet up again And things would be different the next time we wed If I only could hang on and just be her friend I still can’t remember all the best things she said.
We came to the pyramids all embedded in ice He said “There’s a body I’m trying to find If I carry it out it’ll bring a good prize” It was then that I knew what he had on his mind.
The wind it was howling and the snow was outrageous We chopped through the night and we chopped through the dawn When he died I was hoping that it wasn’t contagious But I made up my mind that I had to go on.
I broke into the tomb but the casket was empty There was no jewels no nothing I felt I’d been had When I saw that my partner was just being friendly When I took up his offer I must-a been mad.
I picked up his body and I dragged him inside Threw him down in the hole and I put back the cover I said a quick prayer and I felt satisfied Then I rode back to find Isis just to tell her I love her.
She was there in the meadow where the creek used to rise Blinded by sleep and in need of a bed I came in from the East with the sun in my eyes I cursed her one time then I rode on ahead.
She said “Where ya been ?” I said “No place special ?” She said “You look different” I said “Well I guess” She said “You been gone” I said “That’s only natural” She said “You gonna stay ?” I said “If you want me to, Yeah ”.
Isis oh Isis you mystical child What drives me to you is what drives me insane I still can remember the way that you smiled On the fifth day of May in the drizzling rain.

- The Importance of The Indie Web #
We’re in danger of losing what’s made the Internet the most important medium in history – a decentralized platform where the people at the edges of the networks – that would be you and me – don’t need permission to communicate, create and innovate.
This isn’t a knock on social networks’ legitimacy, or their considerable utility. But when we use centralized services like social media sites, however helpful and convenient they may be, we are handing over ultimate control to third parties that profit from our work, material that exists on their sites only as long as they allow.
Even if most people don’t recognize what’s at stake – yet – I’m happy to say that a small but growing group of technologists does. And they’ve created what they call the “Indie Web” movement to do something about it, in an extended online conversation and at periodic in-person meetings.

- Roman Vishniac: Humanist, Photographer #
Living with the memory of hardship, Vishniac was, “an absolute optimist filled with tragedy. His humanism is not just for Jews, but for every living thing.” He probably believed in God or some similar concept, but he was non-denominational and did not adhere strictly to the principles of any religion. He even clashed with Orthodox Jews in one well-known instance: The religious Jews he met on his trek around Europe would not let themselves be photographed, quoting the Bible and its prohibition of making of graven images. Vishniac’s famous response was, “the Torah existed for thousands of years before the camera had been invented.”
Vishniac was known for having great respect for all living creatures. Whenever possible, he returned a specimen to its precise home before it was captured and one time “[lent] his bathtub to tadpoles for weeks until he could return them to their pond”. In accordance with this philosophy, he photographed almost exclusively living subjects.

Looking into a side of the Milky Way from the Asellus system in Elite: Dangerous. The glowing red star is Asellus Primus B, 0.16 light years away.
Thunder ends the hyperspace jump and we are now in a different here in a different now with glowing orb of fire filling our view. Hazard proximity sensors are going off and we maneuver away toward points of light in the darkness of space — some very bright, others invisible if not for the navigation overlays which indicate the orbits and positions of celestial bodies in this system. We are in Super Cruise mode, a sort of crawling speed setting in the space travel throttle and the ideal way to fly around the local solar system with red and blue-shifting star and dust trails all around.
As we gather speed away from the ball of plasma the blackness of space begins to fade away, gradually revealing the number of other stars there and then. The heavens begin to change colour, blues and violets of interstellar clouds of dust, nebulae illuminating the glinting night, a long section of which is bright as an Earth day. The middle of this bright river of light is the center of our own Milky Way galaxy, another point of which we have reached.
Second burst of thunder and we are now out of Super Cruise in local time where Newton’s maths of motion rule our ballet. Thrusters up, throttle forward, flight assist off, push stick forward slowly, then release. The distant jewels now spin slowly around us in the infinity of the universe. Black sphere with half-circle sliver of light perpendicular to thin illuminated ring of giant dust rises from the horizon of our lower dashboard, followed by a crescent moon, and then a cuboctahedron — a Coriolis station.
Approaching, we feel the size of the station. As towers and other appendages of this spinning city in space fly by our ship we hear the moan of a massive structure. As in film, sound and music help form the whole of our flying experience. Staccato popping-and-buzzing of directional thrusters, twanging sounds of a 1970’s cross-between-VW-bus-and-space-shuttle Hauler ship engine, heaving heavy machinery opening cargo bay or landing gear doors; utter silence followed by crunching of ice crystals forming around cockpit glass panes when switching off systems to reduce heat signature and disappear from sensors. Elite’s orchestra puts us here inside a ship flying in space, our hands and feet on the controls, cockpit’s metal frames moving with inertia casting dancing shadows in pools of colored light from stars, planets, stations, our own and other ships, their engines glinting, tracing a disappearing line in the immensity of the cosmos.
We align ourselves with the the entrance and match the Coriolis’ rotation. Now the stars are moving and we, along with the station, are still.

The best gaming moments are social — we like sharing our experiences with others. I remember playing SimCity 2000 for hours together with a friend in São Paulo. I’d have the controls while he sat next to me and discussed the computer simulation before us.

- Why Racket, Why Lisp #
At the core of Pollen is an argument:
- First, that digital books should be the best books we’ve ever had. So far, they’re not even close.
- Second, that because digital books are software, an author shouldn’t think of a book as merely data. The book is a program.
- Third, that the way we make digital books better than their predecessors is by exploiting this programmability.
That’s what Pollen is for.

- The 1,000 Hour Rule #
- On the Shortness of Life #
The majority of mortals, Paulinus, complain bitterly of the spitefulness of Nature, because we are born for a brief span of life, because even this space that has been granted to us rushes by so speedily and so swiftly that all save a very few find life at an end just when they are getting ready to live. Nor is it merely the common herd and the unthinking crowd that bemoan what is, as men deem it, an universal ill; the same feeling has called forth complaint also from men who were famous. It was this that made the greatest of physicians exclaim that “life is short, art is long;” it was this that led Aristotle, while expostulating with Nature, to enter an indictment most unbecoming to a wise man—that, in point of age, she has shown such favour to animals that they drag out five or ten lifetimes, but that a much shorter limit is fixed for man, though he is born for so many and such great achievements. It is not that we have a short space of time, but that we waste much of it. Life is long enough, and it has been given in sufficiently generous measure to allow the accomplishment of the very greatest things if the whole of it is well invested. But when it is squandered in luxury and carelessness, when it is devoted to no good end, forced at last by the ultimate necessity we perceive that it has passed away before we were aware that it was passing. So it is—the life we receive is not short, but we make it so, nor do we have any lack of it, but are wasteful of it. Just as great and princely wealth is scattered in a moment when it comes into the hands of a bad owner, while wealth however limited, if it is entrusted to a good guardian, increases by use, so our life is amply long for him who orders it properly.

- Email Is Still the Best Thing on the Internet #
Whatever service you use to communicate non-ephemerally on the internet, an email address is needed to do it.
Then during the early 90s, a “hack” was found that created the foundation of most user account systems on the web. That “hack” was the idea of logging into a website with your email address, and proving you were the owner of that email address by having the site send you an SMTP message with a hyperlink back to the site which contained a long code. For the few of us who considered ourselves identity geeks at the time, this did not seem like an approach that would last a long time. Even SMTP seemed like a fad when we already had high end systems like Lotus Notes relying on things like PKI, digital certifications, signing, encryption, etc.
However twenty years later, that “hack” is still the most powerful technique that we rely on to build user account systems. From a purist perspective, emails have some downsides as identifiers. Much of this guide will discuss those downsides, and how to handle them. However nothing else, even phone numbers or social network IDs, has come even close to being as powerful an identifier.

- People Simply Empty Out #
And what hurts is the steadily diminishing humanity of those fighting to hold jobs they don’t want but fear the alternative worse. People simply empty out. They are bodies with fearful and obedient minds. The color leaves the eye. The voice becomes ugly. And the body. The hair. The fingernails. The shoes. Everything does.
As a young man I could not believe that people could give their lives over to those conditions. As an old man, I still can’t believe it. What do they do it for? Sex? TV? An automobile on monthly payments? Or children? Children who are just going to do the same things that they did?
