Really fascinating about all the different definitions of life and how much more complex it gets if you have to find a definition not limited know planet-Earth ones.
“The ability to reproduce—that is the essential characteristic of life” said one statesman of science. Everyone nodded in agreement that the essentials of a life was the ability to reproduce, until one small voice was heard. “Then one rabbit is dead. Two rabbits—a male and female—are alive but either one alone is dead.”

The term Moscow itself is an acronym derived from the first letter of each of four prioritization categories: M - Must have S - Should have C
Both authors started writing right after and as a result of WW2.
As terrifying as all this is, we encounter it in a childlike world where, however bad things get, mother is able to make them right. ‘If only we can get home to mamma before it comes, nothing can happen,’ Moomintroll says anxiously when he learns the time that the comet will hit. ‘She will know what to do.’
The strain this put on the family is transformed into Moominpappa’s absence. He has ‘[taken] off with the Hattifatteners’, ‘who are forever wandering restlessly from place to place in their aimless quest for nobody knows what’. Moominpappa later quietly omits his infatuation with this strange, mindless crowd when he writes the story of his life, which was the approach taken by many Finnish supporters of Nazi Germany. When Moominpappa’s memoirs are complete, there is nothing in them at all about his wayward years with the Hattifatteners, much to Snufkin’s puzzlement.
I’m also not sure whether that is a case of blue curtains or not:
It is in their depiction of gender and sexual fluidity that the stories are most radical. Jansson herself had relationships with both men and women before finally settling, as she put it, on ‘the spook side’, with a female partner, the graphic designer Tuulikki Pietilä. [...] Thingumy and Bob have a secret language and hide the King’s Ruby, which symbolises their love, in a suitcase. But the Groke, who represents the forces of repression and negativity, wants to deprive them of it. In the parody court that the Moomins hold, the Groke’s legal right to the ruby is contrasted with Thingumy and Bob’s moral one. In Moominland Midwinter (1957), Jansson brought Pietilä into the book as the character Too-Ticky; though referred to as ‘she’, Too-Ticky dresses in trousers and Breton tops, with short hair, a beret, and a knife on her belt.

These are excellent, pasting them here in case the apocalypse happens:
It’s my birthday. I’m 68. I feel like pulling up a rocking chair and dispensing advice to the young ‘uns. Here are 68 pithy bits of unsolicited advice which I offer as my birthday present to all of you.
• Learn how to learn from those you disagree with, or even offend you. See if you can find the truth in what they believe.
• Being enthusiastic is worth 25 IQ points.
• Always demand a deadline. A deadline weeds out the extraneous and the ordinary. It prevents you from trying to make it perfect, so you have to make it different. Different is better.
• Don’t be afraid to ask a question that may sound stupid because 99% of the time everyone else is thinking of the same question and is too embarrassed to ask it.
• Being able to listen well is a superpower. While listening to someone you love keep asking them “Is there more?”, until there is no more.
• A worthy goal for a year is to learn enough about a subject so that you can’t believe how ignorant you were a year earlier.
• Gratitude will unlock all other virtues and is something you can get better at.
• Treating a person to a meal never fails, and is so easy to do. It’s powerful with old friends and a great way to make new friends.
• Don’t trust all-purpose glue.
• Reading to your children regularly will bond you together and kickstart their imaginations.
• Never use a credit card for credit. The only kind of credit, or debt, that is acceptable is debt to acquire something whose exchange value is extremely likely to increase, like in a home. The exchange value of most things diminishes or vanishes the moment you purchase them. Don’t be in debt to losers.
• Pros are just amateurs who know how to gracefully recover from their mistakes.
• Extraordinary claims should require extraordinary evidence to be believed.
• Don’t be the smartest person in the room. Hangout with, and learn from, people smarter than yourself. Even better, find smart people who will disagree with you.
• Rule of 3 in conversation. To get to the real reason, ask a person to go deeper than what they just said. Then again, and once more. The third time’s answer is close to the truth.
• Don’t be the best. Be the only.
• Everyone is shy. Other people are waiting for you to introduce yourself to them, they are waiting for you to send them an email, they are waiting for you to ask them on a date. Go ahead.
• Don’t take it personally when someone turns you down. Assume they are like you: busy, occupied, distracted. Try again later. It’s amazing how often a second try works.
• The purpose of a habit is to remove that action from self-negotiation. You no longer expend energy deciding whether to do it. You just do it. Good habits can range from telling the truth, to flossing.
• Promptness is a sign of respect.
• When you are young spend at least 6 months to one year living as poor as you can, owning as little as you possibly can, eating beans and rice in a tiny room or tent, to experience what your “worst” lifestyle might be. That way any time you have to risk something in the future you won’t be afraid of the worst case scenario.
• Trust me: There is no “them”.
• The more you are interested in others, the more interesting they find you. To be interesting, be interested.
• Optimize your generosity. No one on their deathbed has ever regretted giving too much away.
• To make something good, just do it. To make something great, just re-do it, re-do it, re-do it. The secret to making fine things is in remaking them.
• The Golden Rule will never fail you. It is the foundation of all other virtues.
• If you are looking for something in your house, and you finally find it, when you’re done with it, don’t put it back where you found it. Put it back where you first looked for it.
• Saving money and investing money are both good habits. Small amounts of money invested regularly for many decades without deliberation is one path to wealth.
• To make mistakes is human. To own your mistakes is divine. Nothing elevates a person higher than quickly admitting and taking personal responsibility for the mistakes you make and then fixing them fairly. If you mess up, fess up. It’s astounding how powerful this ownership is.
• Never get involved in a land war in Asia.
• You can obsess about serving your customers/audience/clients, or you can obsess about beating the competition. Both work, but of the two, obsessing about your customers will take you further.
• Show up. Keep showing up. Somebody successful said: 99% of success is just showing up.
• Separate the processes of creation from improving. You can’t write and edit, or sculpt and polish, or make and analyze at the same time. If you do, the editor stops the creator. While you invent, don’t select. While you sketch, don’t inspect. While you write the first draft, don’t reflect. At the start, the creator mind must be unleashed from judgement.
• If you are not falling down occasionally, you are just coasting.
• Perhaps the most counter-intuitive truth of the universe is that the more you give to others, the more you’ll get. Understanding this is the beginning of wisdom.
• Friends are better than money. Almost anything money can do, friends can do better. In so many ways a friend with a boat is better than owning a boat.
• This is true: It’s hard to cheat an honest man.
• When an object is lost, 95% of the time it is hiding within arm’s reach of where it was last seen. Search in all possible locations in that radius and you’ll find it.
• You are what you do. Not what you say, not what you believe, not how you vote, but what you spend your time on.
• If you lose or forget to bring a cable, adapter or charger, check with your hotel. Most hotels now have a drawer full of cables, adapters and chargers others have left behind, and probably have the one you are missing. You can often claim it after borrowing it.
• Hatred is a curse that does not affect the hated. It only poisons the hater. Release a grudge as if it was a poison.
• There is no limit on better. Talent is distributed unfairly, but there is no limit on how much we can improve what we start with.
• Be prepared: When you are 90% done any large project (a house, a film, an event, an app) the rest of the myriad details will take a second 90% to complete.
• When you die you take absolutely nothing with you except your reputation.
• Before you are old, attend as many funerals as you can bear, and listen. Nobody talks about the departed’s achievements. The only thing people will remember is what kind of person you were while you were achieving.
• For every dollar you spend purchasing something substantial, expect to pay a dollar in repairs, maintenance, or disposal by the end of its life.
•Anything real begins with the fiction of what could be. Imagination is therefore the most potent force in the universe, and a skill you can get better at. It’s the one skill in life that benefits from ignoring what everyone else knows.
• When crisis and disaster strike, don’t waste them. No problems, no progress.
• On vacation go to the most remote place on your itinerary first, bypassing the cities. You’ll maximize the shock of otherness in the remote, and then later you’ll welcome the familiar comforts of a city on the way back.
• When you get an invitation to do something in the future, ask yourself: would you accept this if it was scheduled for tomorrow? Not too many promises will pass that immediacy filter.
• Don’t say anything about someone in email you would not be comfortable saying to them directly, because eventually they will read it.
• If you desperately need a job, you are just another problem for a boss; if you can solve many of the problems the boss has right now, you are hired. To be hired, think like your boss.
• Art is in what you leave out.
• Acquiring things will rarely bring you deep satisfaction. But acquiring experiences will.
• Rule of 7 in research. You can find out anything if you are willing to go seven levels. If the first source you ask doesn’t know, ask them who you should ask next, and so on down the line. If you are willing to go to the 7th source, you’ll almost always get your answer.
• How to apologize: Quickly, specifically, sincerely.
• Don’t ever respond to a solicitation or a proposal on the phone. The urgency is a disguise.
• When someone is nasty, rude, hateful, or mean with you, pretend they have a disease. That makes it easier to have empathy toward them which can soften the conflict.
• Eliminating clutter makes room for your true treasures.
• You really don’t want to be famous. Read the biography of any famous person.
• Experience is overrated. When hiring, hire for aptitude, train for skills. Most really amazing or great things are done by people doing them for the first time.
• A vacation + a disaster = an adventure.
• Buying tools: Start by buying the absolute cheapest tools you can find. Upgrade the ones you use a lot. If you wind up using some tool for a job, buy the very best you can afford.
• Learn how to take a 20-minute power nap without embarrassment.
• Following your bliss is a recipe for paralysis if you don’t know what you are passionate about. A better motto for most youth is “master something, anything”. Through mastery of one thing, you can drift towards extensions of that mastery that bring you more joy, and eventually discover where your bliss is.
• I’m positive that in 100 years much of what I take to be true today will be proved to be wrong, maybe even embarrassingly wrong, and I try really hard to identify what it is that I am wrong about today.
• Over the long term, the future is decided by optimists. To be an optimist you don’t have to ignore all the many problems we create; you just have to imagine improving our capacity to solve problems.
• The universe is conspiring behind your back to make you a success. This will be much easier to do if you embrace this pronoia.
A classic :)

After a rough initial period, the store proved to be very successful. Warren's goods were much cheaper than competitors', though he maintained that he was not trying to put other stores out of business. Another store in the neighborhood converted to Warren's methods. The fact that prices for goods rose the more time a customer spent with Warren resulted in very efficient transactions. Warren said that he was doing more business in one hour than normal businesses do in one day, leading him to close shop part of the day to rest.
Nonetheless, at the time it was the most popular mercantile institution in Cincinnati

Marx believed that religion had certain practical functions in society that were similar to the function of opium in a sick or injured person: it reduced people's immediate suffering and provided them with pleasant illusions which gave them the strength to carry on. Marx also saw religion as harmful, as it prevents people from seeing the class structure and oppression around them, thus religion can prevent the necessary revolution.

Ants recognize themselves in a mirror. " Consciousness may be far more ancient, far more widespread than we ever suspected."
The other question is “why don’t you see that noise when the TV is tuned in?” The TV has automatic gain control. When the signal is weak, it will amplify it up to the right level. If the signal is just background noise, then it will amplify that background noise until it’s at the “right level” for a proper TV signal. So, the gain is lower for stronger signals, and very high when there is no signal at all.
the artefacts created in the black and white picture by the colour signal are hardly noticeable, but they are enough to recover the colour from a black and white recording!
Excellent about how to measure word similarities, find nearby words etc etc based on a corpus using simple linear algebra and algorithmic tools. What I need for Gesturehand, pretty much.
A useful way to recognize status quo bias is to ask, “What things wouldn’t be allowed if they were introduced today?” Here are some examples.
As recommended by … on the FedCSIS conference
in a simple memory span task, pupil size precisely tracks changes in memory load, '''dilating with each new item held in memory and constricting as each item is [...] recalled '''
High`` ``working`` ``memory`` ``subjects’`` ``pupil`` ``diameters`` ``were`` ``0.97`` ``millimeter`` ``larger
than those with low WMC,
'''Working memory explained 6% of the variance '''in baseline pupil size and with each 1 SD increase in WMC there was a 0.30 mm increase in baseline pupil diameter, b = 0.30, r = 0.24.
Fluid`` ``intelligence`` ``explained`` ``12%`` ``of`` ``the`` ``variance`` ``in`` ``baseline`` ``pupil`` ``size
and each 1 SD increase in Gf was associated with a 0.45 mm increase in baseline pupil diameter,
Additionally, the nice phrase “All grist to the mill.” = All things are a potential source of profit or advantage. ( http://www.phrases.org.uk/meanings/grist-to-the-mill.html )
The von Restorff effect, also known as the "isolation effect", predicts that when multiple homogenous stimuli are presented, the stimulus that differs from the rest is more likely to be remembered.

Excellent way to view learning mathematics and learning in general.
Tetris mindset vs Mega man
"Here's the trick: every boss has a weakness. After you beat Fire-man with your regular gun, you earn a fire weapon. This makes your upcoming fight with Ice-man easier, which helps defeat the next boss, and so on. '''In Mega Man, you look forward to encountering more bosses.'''"
“Think about Tetris: would you look forward to a variety of new shapes appearing? Heck no. Tetris can be fun in a “survive hordes of incoming zombies” sort of way, but in terms of learning, it’s a frustrating, Sisyphean task. Every new piece is something to move beyond, not a learning opportunity. It’s a test to find your breaking point.”
When learning, I ask: "Did I internalize the concept so much I look forward to seeing it?". Learned ideas become allies, a decoder key to help unlock future equations.
intelligence`` ``and`` ``thinking`` ``skill`` ``are`` ``not`` ``directly`` ``related
Verbal facility: Intelligent people learn that
well-articulated`` ``is`` ``often`` ``mistaken`` ``by`` ``others`` ``for`` ``well-thought-out
verbal`` ``skills`` ``come`` ``easier`` ``than`` ``thinking`` ``skills
, the intelligent person is tempted to
substitute`` ``the`` ``former`` ``for`` ``the`` ``latter
Backdoor commitment: An intelligent person can
create`` ``a`` ``rational`` ``and`` ``articulate`` ``argument`` ``to`` ``support`` ``almost`` ``any`` ``position
, sometimes without even examining it. It is very easy for him to then slip into having an emotional stake in the position, not because he has critically evalutated it, but simply because he has pride of ownership of the argument in its favor.
Bias toward criticism:
If`` ``you`` ``advocate`` ``an`` ``idea,`` ``you`` ``make`` ``yourself`` ``vulnerable`` ``to`` ``the`` ``criticism`` ``of`` ``others.`` ``If`` ``you`` ``shoot`` ``down`` ``others’`` ``ideas,`` ``you`` ``get`` ``to`` ``be`` ``the`` ``one`` ``who`` ``showed`` ``others`` ``they`` ``were`` ``wrong.`` ``This`` ``behavior`` ``can`` ``be`` ``very`` ``seductive.
It is also self-reinforcing: once you have been the critic for a while, you visualize others doing to your ideas what you routinely do to theirs, and are therefore even less inclined to put forward new ideas of your own.
The “Everest effect”: Intelligent people often seem to prefer reactive and analytic thinking over projective and synthetic thinking. In reactive thinking the problem is there before you and you have to respond, usually on the problem’s own terms. In projective thinking, you have to find the problem, the objectives, and the solution space. Reactive and analytic thinking appeals to intelligent people the way a big mountain appeals to skilled mountain climbers: because it’s there. However, most of the important problems in life require projective and synthetic thinking.
Is this what MBTI calls rationality vs intuition? + in indian mythology there was something about the logic that divides to atoms to understand vs logic which understands things by having them whole
Speed: Because an intelligent person can
reach`` ``a`` ``conclusion`` ``without`` ``walking`` ``through`` ``all`` ``the`` ``intermediate`` ``steps,`` ``he`` ``is`` ``tempted`` ``to`` ``do`` ``so
. But some of the intermediate steps may be important and reveal considerations that make the easy conclusion inappropriate.
See suggestions that cognitive bias is mildly correlated with iq; find better sources than http://www.newyorker.com/tech/frontal-cortex/why-smart-people-are-stupid
Bias toward cleverness: There are greater social rewards for demonstrated cleverness than for demonstrated wisdom. This can lead the intelligent person to habitually retreat into cleverness.
How is this different from “Everest effect” and “Bias towards criticism”?
general relationship between the initial intensity of something and the smallest detectable increment is exactly what Weber noticed and formalized into “Weber’s Law”.
Another take on this is http://spectrum.ieee.org/podcast/biomedical/bionics/does-the-brain-work-logarithmically Relevant: about how easy it is to point at stuff I need a category for the intersection between Psychology and mathematical laws
More data = more ways to create the picture you want or need; also different videos shown give a different reaction
Seen at speed, his raising of his hand looked nothing more than an involuntary and instinctive act of self-defence. Viewed in slow motion (as the third umpire saw it), it seemed a wilful and deliberate act of wicket–preservation. In the first instance, everything happened so quickly that it seemed impossible that Stokes had time to think; in slow motion it seemed impossible that he hadn’t.
those ‘juries’ shown a slow-motion replay were more than three times as likely to convict as those who saw events at the correct speed. The effect diminished when the footage was shown at both speeds, but persisted: such juries were still one and a half times more disposed to find the gunman guilty.
A fairly good rule of thumb is that the more data you have, the more gold is contained therein… but at the price of an even greater volume of false gold
Constructing an inaccurate but plausible narrative is much easier when you can cherry-pick from 50 pieces of information than from five.

Students made to feel a lack of control more often reported seeing images of animals, people, or foods where none existed.
“Superstitions create a form of structure in an unstructured world,”
“Engaging in superstitious behavior creates a subsequent illusion of control over future outcomes.”
It turns out that if what you do is really risky and dangerous, or involves lots of uncertainty, then you’re more likely to hold and practice superstitions. It’s not just sailing. Gambling, Wall Street trading, and baseball are just a few more examples.
Schizophrenia in the family, mood disorders (esp. bipolar and depression), ability to find connections between ideas, high (but not necessarily exceptionally high) IQ seem to cover everything pretty well.
The "sweater curse" or "curse of the love sweater" is a term used by knitters to describe the belief that if a knitter gives a hand-knit sweater to a significant other, it will lead to the recipient breaking up with the knitter. In an alternative formulation, the relationship will end before the sweater is even completed. The belief is widely discussed in knitting publications, and some knitters claim to have experienced it

What I’ve always done explained much better than I ever could. The way we call (=think about) a concept can dramatically change how well we understand it and can use it. Take away point is thinking well about the importance of the metaphors we choose to use.
