Today's Orlando Sentinel features, on its opinion page, a wonderful article by guest columnist James O. Cunningham: What's wrong with America? 'Dear Sir, I am'. The link takes you to the front page, from which you could click to page 12—or maybe not; it's not clear to me which parts the newspaper makes available to non-subscribers. But the Sentinel also makes it possible to clip and save articles, and this one deserves wider publicity, so I've included it below. If you find the print too small, click on the image for a larger version. (H/T Porter, who grabbed my attention by mentioning the Chesterton quote.)

Google frequently suggests, through my phone, articles that it thinks I might find interesting. Most of the time it's not even close: Really, I don't want to know what President Trump tweeted, any more than I wanted to hear what President Obama said on Saturday Night Live. I consider both to be inappropriate venues for a President. But recently Google was whang in the gold, with its suggestion of the video below from musician Rick Beato.

Not the whole video, actually. Mostly it's about acquiring the musical skill known as perfect (absolute) pitch, and why Beato believes it must occur during a child's first two years of life. He makes a good case, but it's a controversial point, and he apparently takes no account of recent studies demonstrating neuroplasticity in adult brains—something previously considered to be impossible. In any case, Beato himself doesn't mean adults can't develop really, really good relative pitch and get quite close to absolute pitch; after all, he has created several YouTube videos on how to do just that. But babies ... they're still something special.

The part of the video I find most intriguing is from the 6 minute point to about the 13 minute point.

One thing that surprised me, although in retrospect it should not have, is that Beato's son's acquired his ability to discern and remember pitches well before he knew any note names. But this post is not really about perfect pitch. It's also not about me feeling guilty for the opportunities lost with our children, and certainly not about making anyone else feel guilty for their own omissions. We do what we can with what we know at the time, and regrets are part of every parenthood contract. My concerns now are more general and philosophical.

What strikes me here—and it confirms what I've learned from other sources—is that our teaching habits are upside down.

Apparently, what helps babies learn is complexity. Materials with high information content. Unexpected twists and turns. So what do we do? We simplify everything for children. We give them baby talk, controlled-vocabulary books, and three-chord songs, when their brains are craving adult conversations, complex language, Bach, and jazz. Sure, they learn anyway: Babies are so desperate to learn they'll use whatever tools they can get their hands on. But despite the best of intentions, we are building cages where we should be opening doors.

Warning: This is an unabashed Grandma-brag—but it has a generally-applicable point as well.

One of my recurrent themes here is the truth that children can do and be so much more than we usually expect of them, from toddlers to teenagers. While our thirteen-year-old grandson's accomplishment is not on a par with commanding a captured naval vessel at the age of 12, nor with captaining a trading ship at 19, I'm quite proud of him—and his parents.


In his right hand is an oak board, similar to that from which he made the object in his left hand, which, when painted, will replace the barber-pole coat rack at a local barbershop.

When he approached the barber, who had advertised for someone to do the work, it took guts and skill to negotiate the commission, not to mention to persuade the barber that a young teen could do the job.

It was an ambitious project, and required working with some heavy-duty power tools—radial arm saw, lathe, planer, and jointer—knowing not only their operation, but proper safety equipment and procedures as well. It was a time-consuming job that required patience. persistence, and focus. That's pretty impressive at an age when many consider him too young to fly unaccompanied on a commerical airplane, to own a knife, or even to stay home alone.

He can cook full meals, too, and I don't mean just heating things up in the microwave.

Is he some sort of genius?  Of course he is, he's my grandchild!

But seriously, what distinguishes him the most from many young people is opportunity. His parents didn't just turn him loose among those dangerous tools, unprepared. He's been helping in the workshop (and the kitchen) since he was a toddler. So have his siblings. The kind of training that produces skills of this sort requires patience and persistence on the part of parents, too—and even more so, a willingness to stand up for the right of children to fly in a society determined to clip their wings.

I'm so glad that the ending of the Space Shuttle program did not mean the end of being able to watch launches from our front yard.

The article may be a little heavy-going, but I know some of my readers will love it. It's not often number theory makes the headlines: Mathematicians Discover Prime Conspiracy. Maybe it's the idea of conspiracy—that always sells.

Two mathematicians have uncovered a simple, previously unnoticed property of prime numbers — those numbers that are divisible only by 1 and themselves. Prime numbers, it seems, have decided preferences about the final digits of the primes that immediately follow them.

Among the first billion prime numbers, for instance, a prime ending in 9 is almost 65 percent more likely to be followed by a prime ending in 1 than another prime ending in 9. In a paper posted online today, Kannan Soundararajan and Robert Lemke Oliver of Stanford University present both numerical and theoretical evidence that prime numbers repel other would-be primes that end in the same digit, and have varied predilections for being followed by primes ending in the other possible final digits.

The discovery is the exact opposite of what most mathematicians would have predicted... Most mathematicians would have assumed ... that a prime should have an equal chance of being followed by a prime ending in 1, 3, 7 or 9.

Soundararajan was drawn to study consecutive primes after hearing a lecture at Stanford by the mathematician Tadashi Tokieda, of the University of Cambridge, in which he mentioned a counterintuitive property of coin-tossing: If Alice tosses a coin until she sees a head followed by a tail, and Bob tosses a coin until he sees two heads in a row, then on average, Alice will require four tosses while Bob will require six tosses (try this at home!), even though head-tail and head-head have an equal chance of appearing after two coin tosses.

Soundararajan wondered if similarly strange phenomena appear in other contexts. Since he has studied the primes for decades, he turned to them — and found something even stranger than he had bargained for.

What does this mean for ordinary mortals? Who knows? It may mean nothing ... or it may lead to the next big break in cryptography. With math, anything's possible.

J. R. R. Tolkien said that Leaf by Niggle was the only one of his stories that wrote itself. It has long held a special place in my heart, though it has none of the majesty and glory of his Lord of the Rings books.

I hope the copyright holders will forgive me for the rather long quotation below. It is only the beginning of the story; the best part is yet to come, and I strongly urge you to find your own copy and read it all. Mine is included as part of "Tree and Leaf" in The Tolkien Reader. Apparently there is a stand-alone version, but unfortunately nothing for Kindle.

As I said, the best part, the really beautiful part, comes later in the story. But this beginning captures so perfectly the dilemmas of creative people: How to balance the demands and pleasures of "real life"with the deep-seated, sometimes almost desperate need to "work, for the night is coming" on one's own, particular calling. At least, this is my own experience, and, I'm convinced, that of Tolkien himself. Perhaps other creative people, of whom I know many among my readers, will find a resonance here.

And then go and read the Rest of the Story for encouragement.

There was once a little man called Niggle, who had a long journey to make. He did not want to go, indeed the whole idea was distasteful to him; but he could not get out of it. He knew he would have to start some time, but he did not hurry with his preparations.

Niggle was a painter. Not a very successful one, partly because he had many other things to do. Most of these things he thought were a nuisance; but he did them fairly well, when he could not get out of them: which (in his opinion) was far too often. The laws in his country were rather strict. There were other hindrances, too. For one thing, he was sometimes just idle, and did nothing at all. For another, he was kind-hearted, in a way. You know the sort of kind heart: it made him uncomfortable more often than it made him do anything; and even when he did anything, it did not prevent him from grumbling, losing his temper, and swearing (mostly to himself). All the same, it did land him in a good many odd jobs for his neighbour, Mr. Parish, a man with a lame leg. Occasionally he even helped other people from further off, if they came and asked him to. Also, now and again, he remembered his journey, and began to pack a few things in an ineffectual way: at such times he did not paint very much.

He had a number of pictures on hand; most of them were too large and ambitious for his skill. He was the sort of painter who can paint leaves better than trees. He used to spend a long time on a single leaf, trying to catch its shape, and its sheen, and the glistening of dewdrops on its edges. Yet he wanted to paint a whole tree, with all of its leaves in the same style, and all of them different.

There was one picture in particular which bothered him. It had begun with a leaf caught in the wind, and it became a tree; and the tree grew, sending out innumerable branches, and thrusting out the most fantastic roots. Strange birds came and settled on the twigs and had to be attended to. Then all round the Tree, and behind it, through the gaps in the leaves and boughs, a country began to open out; and there were glimpses of a forest marching over the land, and of mountains tipped with snow. Niggle lost interest in his other pictures; or else he took them and tacked them on to the edges of his great picture. Soon the canvas became so large that he had to get a ladder; and he ran up and down it, putting in a touch here, and rubbing out a patch there. When people came to call, he seemed polite enough, though he fiddled a little with the pencils on his desk. He listened to what they said, but underneath he was thinking all the time about his big canvas, in the tall shed that had been built for it out in his garden (on a plot where once he had grown potatoes).

He could not get rid of his kind heart. "I wish I was more strong-minded!" he sometimes said to himself, meaning that he wished other people's troubles did not make him feel uncomfortable. But for a long time he was not seriously perturbed. "At any rate, I shall get this one picture done, my real picture, before I have to go on that wretched journey," he used to say. Yet he was beginning to see that he could not put off his start indefinitely. The picture would have to stop just growing and get finished.

One day, Niggle stood a little way off from his picture and considered it with unusual attention and detachment. He could not make up his mind what he thought about it, and wished he had some friend who would tell him what to think. Actually it seemed to him wholly unsatisfactory, and yet very lovely, the only really beautiful picture in the world. What he would have liked at that moment would have been to see himself walk in, and slap him on the back, and say (with obvious sincerity): "Absolutely magnificent! I see exactly what you are getting at. Do get on with it, and don't bother about anything else! We will arrange for a public pension, so that you need not."

However, there was no public pension. And one thing he could see: it would need some concentration, some work, hard uninterrupted work, to finish the picture, even at its present size. He rolled up his sleeves, and began to concentrate. He tried for several days not to bother about other things. But there came a tremendous crop of interruptions. Things went wrong in his house; he had to go and serve on a jury in the town; a distant friend fell ill; Mr. Parish was laid up with lumbago; and visitors kept on coming. It was springtime, and they wanted a free tea in the country: Niggle lived in a pleasant little house, miles away from the town. He cursed them in his heart, but he could not deny that he had invited them himself, away back in the winter, when he had not thought it an "interruption" to visit the shops and have tea with acquaintances in the town. He tried to harden his heart; but it was not a success. There were many things that he had not the face to say no to, whether he thought them duties or not; and there were some things he was compelled to do, whatever he thought. Some of his visitors hinted that his garden was rather neglected, and that he might get a visit from an Inspector. Very few of them knew about his picture, of course; but if they had known, it would not have made much difference. I doubt if they would have thought that it mattered much. I dare say it was not really a very good picture, though it may have had some good passages. The Tree, at any rate, was curious. Quite unique in its way. So was Niggle; though he was also a very ordinary and rather silly little man.

At length Niggle's time became really precious. His acquaintances in the distant town began to remember that the little man had got to make a troublesome journey, and some began to calculate how long at the latest he could put off starting. They wondered who would take his house, and if the garden would be better kept.

The autumn came, very wet and windy. The little painter was in his shed. He was up on the ladder, trying to catch the gleam of the westering sun on the peak of a snow-mountain, which he had glimpsed just to the left of the leafy tip of one of the Tree's branches. He knew that he would have to be leaving soon: perhaps early next year. He could only just get the picture finished, and only so so, at that: there were some corners where he would not have time now to do more than hint at what he wanted.

There was a knock on the door. "Come in!" he said sharply, and climbed down the ladder. He stood on the floor twiddling his brush. It was his neighbour, Parish: his only real neighbour, all other folk lived a long way off. Still, he did not like the man very much: partly because he was so often in trouble and in need of help; and also because he did not care about painting, but was very critical about gardening. When Parish looked at Niggle's garden (which was often) he saw mostly weeds; and when he looked at Niggle's pictures (which was seldom) he saw only green and grey patches and black lines, which seemed to him nonsensical. He did not mind mentioning the weeds (a neighbourly duty), but he refrained from giving any opinion of the pictures. He thought this was very kind, and he did not realize that, even if it was kind, it was not kind enough. Help with the weeds (and perhaps praise for the pictures) would have been better.

"Well, Parish, what is it?" said Niggle.

"I oughtn't to interrupt you, I know," said Parish (without a glance at the picture). "You are very busy, I'm sure."

Niggle had meant to say something like that himself, but he had missed his chance. All he said was: "Yes."

"But I have no one else to turn to," said Parish.

"Quite so," said Niggle with a sigh: one of those sighs that are a private comment, but which are not made quite inaudible. "What can I do for you?"

"My wife has been ill for some days, and I am getting worried," said Parish. "And the wind has blown half the tiles on my roof, and water is pouring into the bedroom. I think I ought to get the doctor. And the builders, too, only they take so long to come. I was wondering if you had any wood and canvas you could spare, just to patch me up and see me through for a day or two." Now he did look at the picture.

"Dear, dear!" said Niggle. "You are unlucky. I hope it is no more than a cold that your wife has got. I'll come round presently, and help you move the patient downstairs."

"Thank you very much," said Parish, rather coolly. "But it is not a cold, it is a fever. I should not have bothered you for a cold. And my wife is in bed downstairs already. I can't get up and down with trays, not with my leg. But I see you are busy. Sorry to have troubled you. I had rather hoped you might have been able to spare the time to go for the doctor, seeing how I'm placed: and the builder too, if you really have no canvas you can spare."

"Of course," said Niggle; though other words were in his heart, which at the moment was merely soft without feeling at all kind. "I could go. I'll go, if you are really worried."

"I am worried, very worried. I wish I was not lame," said Parish.

So Niggle went. You see, it was awkward. Parish was his neighbour, and everyone else a long way off. Niggle had a bicycle, and Parish had not, and could not ride one. Parish had a lame leg, a genuine lame leg which gave him a good deal of pain: that had to be remembered, as well as his sour expression and whining voice. Of course, Niggle had a picture and barely time to finish it. But it seemed that this was a thing that Parish had to reckon with and not Niggle. Parish, however, did not reckon with pictures; and Niggle could not alter that. "Curse it!" he said to himself, as he got out his bicycle.

It was wet and windy, and daylight was waning. "No more work for me today!" thought Niggle, and all the time that he was riding, he was either swearing to himself, or imagining the strokes of his brush on the mountain, and on the spray of leaves beside it, that he had first imagined in the spring. His fingers twitched on the handlebars. Now he was out of the shed, he saw exactly the way in which to treat that shining spray which framed the distant vision of the mountain. But he had a sinking feeling in his heart, a sort of fear that he would never now get a chance to try it out.

Niggle found the doctor, and he left a note at the builder's. The office was shut, and the builder had gone home to his fireside. Niggle got soaked to the skin, and caught a chill himself. The doctor did not set out as promptly as Niggle had done. He arrived next day, which was quite convenient for him, as by that time there were two patients to deal with, in neighbouring houses. Niggle was in bed, with a high temperature, and marvellous patterns of leaves and involved branches forming in his head and on the ceiling. It did not comfort him to learn that Mrs. Parish had only had a cold, and was getting up. He turned his face to the wall and buried himself in leaves.

He remained in bed some time. The wind went on blowing. It took away a good many more of Parish's tiles, and some of Niggle's as well: his own roof began to leak. The builder did not come. Niggle did not care; not for a day or two. Then he crawled out to look for some food (Niggle had no wife). Parish did not come round: the rain had got into his leg and made it ache; and his wife was busy mopping up water, and wondering if "that Mr. Niggle" had forgotten to call at the builder's. Had she seen any chance of borrowing anything useful, she would have sent Parish round, leg or no leg; but she did not, so Niggle was left to himself.

At the end of a week or so Niggle tottered out to his shed again. He tried to climb the ladder, but it made his head giddy. He sat and looked at the picture, but there were no patterns of leaves or visions of mountains in his mind that day. He could have painted a far-off view of a sandy desert, but he had not the energy.

Next day he felt a good deal better. He climbed the ladder, and began to paint. He had just begun to get into it again, when there came a knock on the door.

"Damn!" said Niggle. But he might just as well have said "Come in!" politely, for the door opened all the same. This time a very tall man came in, a total stranger.

"This is a private studio," said Niggle. "I am busy. Go away!"

"I am an Inspector of Houses," said the man, holding up his appointment-card, so that Niggle on his ladder could see it. "Oh!" he said.

"Your neighbour's house is not satisfactory at all," said the Inspector.

"I know," said Niggle. "I took a note to the builders a long time ago, but they have never come. Then I have been ill."

"I see," said the Inspector. "But you are not ill now."

"But I'm not a builder. Parish ought to make a complaint to the Town Council, and get help from the Emergency Service."

"They are busy with worse damage than any up here," said the Inspector. "There has been a flood in the valley, and many families are homeless. You should have helped your neighbour to make temporary repairs and prevent the damage from getting more costly to mend than necessary. That is the law. There is plenty of material here: canvas, wood, waterproof paint."

"Where?" asked Niggle indignantly.

"There!" said the Inspector, pointing to the picture.

"My picture!" exclaimed Niggle.

"I dare say it is," said the Inspector. "But houses come first. That is the law."

"But I can't . . ." Niggle said no more, for at that moment another man came in. Very much like the Inspector he was, almost his double: tall, dressed all in black.

"Come along!" he said. "I am the Driver."

Niggle stumbled down from the ladder. His fever seemed to have come on again, and his head was swimming; he felt cold all over.

"Driver? Driver?" he chattered. "Driver of what?"

"You, and your carriage," said the man. "The carriage was ordered long ago. It has come at last. It's waiting. You start today on your journey, you know."

"There now!" said the Inspector. "You'll have to go; but it's a bad way to start on your journey, leaving your jobs undone. Still, we can at least make some use of this canvas now."

"Oh, dear!" said poor Niggle, beginning to weep. "And it's not, not even finished!"

"Not finished?" said the Driver. "Well, it's finished with, as far as you're concerned, at any rate. Come along!"

Niggle went, quite quietly. The Driver gave him no time to pack, saying that he ought to have done that before, and they would miss the train; so all Niggle could do was to grab a little bag in the hall. He found that it contained only a paint-box and a small book of his own sketches: neither food nor clothes. They caught the train all right. Niggle was feeling very tired and sleepy; he was hardly aware of what was going on when they bundled him into his compartment. He did not care much: he had forgotten where he was supposed to be going, or what he was going for. The train ran almost at once into a dark tunnel.

I suppose many visionaries were also potty mouths, and I also suspect Elon Musk's new rocket dream, the BFR, owes its name as much to Roald Dahl's Big Friendly Giant (BFG) as anything. Dahl was a potty mouth, too, just not as obvious about it to his intended audience.

Be that as it may, Musk dreams big.


This Daily Mail article explains his plan to revolutionize earth transportation.

Musk said the vessel would both take off and land vertically, like a space rocket, and for Earth travel, will take off from floating launchpads moored outside major cities. 

It would fly most routes - New York to Tokyo, for example - in about 30 minutes, and anywhere in under an hour, and Musk says the 'cost per seat should be about the same as full fare economy in an aircraft.'

The science fiction fan in me says, "It's about time!"

The realist in me says, "I'll believe it when I see it."

The cynic in me says, "Those impressive flight time numbers fail to take into account the time it takes to get to the launchpad and through security screening, which is what really drags down today's transportation times."

Nonetheless, it seems as if the future of my beloved childhood science fiction novels is coming closer, for good and for ill.
