10 trillion galaxies times 100 billion stars. One trillion squared. That's what we are talking about. In addition, the universe is possibly 250 times larger than the observable universe. Mind boggling.
First Observed Interstellar Object
'Oumuamua is possibly a lightsail object sent for observation, and in any case is definitely from outside the solar system (from another solar system altogether).
> Last year, the first unambiguously interstellar object, 'Oumuamua, flew through our Solar System, delighting and amazing astronomers worldwide. Coming in at a steep angle with an incredibly large speed and a bizarre, cigar-like shape, it must have originated far away and long ago, most likely from a distant star system.
Now that my eldest son is 3 years old, there may be some changes to his schedule (he still takes a nap most days, but he is staying up past his traditional bedtime, so this became a question for me: How much sleep is enough?
Well, there is a range of answers, depending on ages, such as:
Age group | Recommended amount of sleep
--------------- | ---------------------------
Newborns | 14 to 17 hours a day
12 months | About 10 hours at night, plus 4 hours of naps
2 years | About 11 to 12 hours at night, plus a 1- to 2-hour afternoon nap
3 to 5 years | 10 to 13 hours
6 to 13 years | 9 to 11 hours
14 to 17 years | 8 to 10 hours
Adults | 7 to 9 hours
*Note that there are differences in particular circumstances such as illness, pregnancy, and the like.
With teeth and teeth brushing comes the need to sleep through the night, or at least change the nighttime feeding into nighttime watering. Turns out that this happens about the same time as toothbrushing should, or somewhat thereafter.
We are entering the zone of the final few months of the baby's first year. At 10 months, kicking dad throughout the night has gotten a bit old. So it is time to make several changes:
- Nighttime weaning
- More and better tooth brushing
The question is the correct method and also sequencing. Probably the most traumatizing should come first.
> There will be sleeping enough in the grave. --Benjamin Franklin
Polyphasic Sleep is when sleep occurs at more than one point in the 24-hour cycle. Otherwise known as napping, it is possible to shorten the length of sleep for all sleep periods and end up with less time overall spent sleeping. The reason this is possible, is that the sleep periods (theoretically) become more efficient in delivering the kind of sleep needed for restfulness. Power-napping is another term for this, but the power part comes from a compression of sleep stages.
Some people are able to supposedly get by on 3 hours of sleep this way, and it has been ascribed to such people as Thomas Edison and Winston Churchill among others.
Benefits of Sleeping Less and More Often
The purported benefits besides an increase in available time (quantity) include as well quality indicators such as increased alertness, creativity and health. However these benefits have been (somewhat) debunked on Supermemo. The main issue that they take with this practice is that sleep deprivation is necessary in order to entrain one's sleep pattern.
This is obviously true... Or is it? If my current sleep pattern is not actually natural (quite a bit of historical as well as EEG evidence that humans are naturally diphasic).
The rather heroic Uberman sleep schedule, which is 20-30 minutes of sleep every four hours, is not something I am going to try for. I don't need that much of a change and also, there doesn't seem to be much room for error there regarding the actual function of sleep. Instead, all I need to do as a result is one more hour of productivity without any loss of energy/alertness, etc. I intend to do more reading and more exercise during this time bonus, if and when it arrives.
Five Interval Sleep Phase
My initial experiment (beginning 11-AUG-2012) will be one hour sleep periods five times per day, at approximately:
This fits my schedule which is fairly flexible, but needs a 4am wakeup for early morning running, a 10am-12pm classes and 3pm meetings several times per week. This also allows me to have an early dinner (at 5pm) or late dinner (7pm+), and not need to sleep at night until 11pm. Also this would allow me to do a late night dancing from midnight to 3am (which my current monophasic sleep does not allow).
Updates on Sleep Experiment
Day 1: Took the naps during the day, and had more energy, but got tired (as always) later in the evening. Slept from 11pm-4am. Which means I had 8 hours of sleep (which is more than I usually do). Therefore slept more, ate more, and had more energy.
Day 2: Similar to day 1. Took naps (the 2pm was difficult, only 30 minutes and got back up). Instead of the 6pm nap, went for a two hour Thai massage. Then to bed at 10:30pm. Heard the 1am alarm but ignored it. Heard the 3am alarm (to nap again), thought of getting up, but didn't. Heard the 4am alarm and then stayed in bed. Got up at 5am for the run. This mean 8.5 hours of sleep. Even more!
Day 3: ...
Conclusion on Sleep
I've learned this isn't going to work out, I am sleeping more, not less. And there are times I put off the nap, can't get to sleep, can't wake up easily, and also the habit of sleeping through much of the night. However, my awareness of sleep and its effect has dramatically increased. There are some studies which conclude that modern man is basically sleep-deprived and this has disastrous effects regarding accident rates, attention in the workplace, not to mention basic physical well-being.
I've come to realize, especially at my advancing age in the upper 40s, that sleep and naps should be grabbed at every reasonable opportunity.
Well, it turns out, there is no such thing, per se, as an IPA Keyboard Layout, at least not in the sense that there are keyboard layouts for various languages and layout styles (e.g., English, Dvorak, etc.). This seems to me to be a tremendous oversight, though it obviously came about because someone thought supporting the entire Unicode space for the IPA was a great idea, and the only idea.
Jeff Bezos and Steve Jobs have similar insights when it comes to hiring the best. This is equally relevant when one is building a school. Hire the best teachers possible, if you want a high-performing school.
Three Questions When Making a Hiring Decision
From the 1998 Amazon Shareholder Letter:
It would be impossible to produce results in an environment as dynamic as the Internet without extraordinary people. Working to create a little bit of history isn't supposed to be easy, and, well, we're finding that things are as they're supposed to be! We now have a team of 2,100 smart, hard-working, passionate folks who put customers first.
Setting the bar high in our approach to hiring has been, and will continue to be, the single most important element of Amazon.com's success. During our hiring meetings, we ask people to consider three questions before making a decision:
- Will you admire this person? If you think about the people you've admired in
your life, they are probably people you've been able to learn from or take an
example from. For myself, I've always tried hard to work only with people I
admire, and I encourage folks here to be just as demanding. Life is definitely too
short to do otherwise.
- Will this person raise the average level of effectiveness of the group they're
entering? We want to fight entropy. The bar has to continuously go up. I ask
people to visualize the company 5 years from now. At that point, each of us
should look around and say, The standards are so high now -- boy, I'm glad I got
in when I did!
- Along what dimension might this person be a superstar? Many people have
unique skills, interests, and perspectives that enrich the work environment for all
of us. It's often something that’s not even related to their jobs.
Steve Jobs on Hiring Truly Gifted People
> In Software, and it used to be the case in Hardware, the difference between the average and the best is 50 to 1, maybe 100 to one....
> I've built a lot of my success off finding these truly gifted people, and not settling for B and C players, but really going for the A players. And I found that when you get these A players together, when you go through this incredible work to find these A players, they really like working with each other becuase they've never had a chance to do that before. And they don't want to work with B and C players, and so it becomes self-policing, and they only want to hire more A players. And so you build up these pockets of A players and it propagates.
For various reasons, now is a terrible time (in the world). At the same time, my own time horizons have shifted due to having young children. My eldest may graduate from high school in 15 years, give or take a year or two. Fifteen years from now is 2033, which is a bit mind boggling. Though to be honest, 2018 is a bit crazy as well, having snuck up on us, in some respects.
How can our actions remain relevant in the face of the likely dramatic and mostly unknown changes we will face by 2033? This is an actual question that deserves at least a method, an approach. To begin, it seems that we need an understanding the kind of world we hope it might be and the skills and abilities needed to get it there.
- Human and humane
- The robots have not taken over (everything, yet)
- Resiliant, and moreso, able to rebound from severe shock (antifragility)
What is most plausible as important and relevant to that time in the future includes:
- War for talent and winner-take-all trends continue
- Population demographics will shift, but current living populations and at least some continuation of demographic trends will have important effects
- China and Thailand will be in population decline; India will have likely added 200m to its population and surpased China as most populous; USA will have increased by 10% to 360m. Indonesia will have increased by nearly 15% with likely 300m.
Regarding some of the bad actors, I sure hope that by 2033 we see a vast diminishment of Facebook, at the very least. We need to see it as a very bad actor (profiting from and thereby enabling bad actors), and as something to shun. Gamification in general seems to be a bad idea, since it develops short-term reward-seeking behavior and has implications for personality development and psychological health.
The ability to think deeply and reason effectively, and to fundamentally love truth and love wisdom. And with this kind of impetus to also include a strong safety net and services dealing with public health both physical and mental.
A bias towards action and foremost action that is directed to realizing a better outcome in the world. Mere consumerism and mere activism are neither not enough. Embodying the mustering of forced directed toward the long term in a bohemian lifestyle rather than a political movement. That is a better lived reality, and one that is harder to attack and overturn. Yet it is fundamentally committed and progressive.

Note: other titles (with different duties) for the household staff include: Au Pair, Governor/Tutor, Nanny, &c.
We are looking (again) for someone to perform the duties of Au Pair. Unfortunately there are two aspects we've been getting wrong:
- An Au Pair is not usually expected to do general cleaning, and
- An Au Pair is usually provided accommodation
We've been including the first and disincluding the second, which limits things a bit. That said, getting it wrong is how to learn to get it right.
Character Attributes of an Au Pair
Kindness, Firmness, Patience, Energy
Enjoy physical work (lugging around an infant/toddler/child takes strength and effort)
Flexibility of style in dealing with the children (as they grow, they enter different stages of development and what works with a 1 year old generally doesn't with a 2 year old)
Good language skills in at least one language
Good presentation of self in terms of grooming, carriage (I realize this sounds very 19th century, but children pick up every kind of mannerism and habit from adults they are around
Not addicted to social media, and able to turn off the phone for hours at a time
Able to communicate questions and information back to the parents
To get an idea of our fellow countrymen’s miseries, we have only to take a look at their pleasures.
