a 'I really know better than to post this post...'

a minipost

About this time of year I get a request or two to talk to a high school junior or senior about colleges and majors.  I'll give reasons why I'm not the best the person to talk to, but if they persist I'll spend some time listening and talking.  Curiously there have been three so far this year and two suggested I post something.  Perhaps it can spark you into helping some students - many of you have much richer backgrounds.

 

A caveat is that I came from a position of privilege: white male, reasonably good at math, and from a period of time when great positive change seemed possible.  I didn't view college as training for work.  Somehow I knew what I was curious about from the age of twelve, so it was just following a calling.  I knew I could always get work with the friend of the family in back home who had a thriving HVAC and water softener company. This gave me the freedom to follow a somewhat different path than friends who were thinking about what happened after graduation.   This led to good and bad choices.  I double majored, but the fields were too close to each other and I ended up with a narrow undergrad education. Since then I study a few areas on my own, but I didn't take advantage of a broader education back then.  On a more positive note I got to know several professors as friends and mentors. That part was priceless.

 

° Ask yourself why you want to go to college?  What is your drive?  Many answers are correct, but you should know yours.

 

° A 'what color is your parachute-ish' question: are there any kinds of work you would do for nothing or even pay to do? 

 

° Where may or may not be important.  It's a plus in some fields to attend a famous college, but in many cases the quality of education can be as good at state schools - sometimes even better if you're good at making connections and really dive into the courses.  Famous professors often don't have the time to talk to undergrads. 

 

° Spend some time finding out which professors can teach.  

 

° Double major if you can, but in mostly unrelated areas.  Even if you're focused on employment afterwards - a good ROI on college - choose the second major in a field that you might find fascinating.  The humanities can give you great depth and are underrated for turning you into someone who can think differently down the road.  I've mentored students with a variety of double majors: CS-music, CS-art, physics-philosophy, math-paleontology for example. If you're doing a D-I sport, consider that a major by itself.  It can give a rich training that can serve you down the line too.  If not a double major, make sure your minor is very different from the major.

 

° A benefit of getting to know professors and show an interest is you might be able to get in on some of their projects.  This is often in the form of work-study, which can take a bite out of the debt down the road.  I was lucky enough to get in on a few great projects.  The most interesting seemed boring at first and didn't pay, but it was in an area I hadn't thought about and the professor was brilliant.  There was even an opportunity to have a tiny contribution to a bit of history and I still use some of the learnings. 

 

° Remind yourself that you learn best when it's play.  This won't happen all of the time - or even most of the time - but work on it. 

 

° Learn to witness the immediate world around you in some depth.  I recommend basic drawing and field drawing courses.  There are many other paths, but a bit of time focusing on understanding the natural world around you changes the way you think. 

 

That's pretty much it.  I mainly listen to them. Some of the items I've mentioned cause them to react and think about their own situation.  This year I recommended How to be Perfect by Michael Schur.  It's basically a Philosophy 101 short course done in a brilliantly entertaining manner - the way an engaged professor might go at it.  (If you're interested the audiobook is much better than the printed version as Schur has a stage background.) 

 

when not keeping your cool is a virtue

Why are we paying someone to heat parts of our house we aren't in?

 

This was one of my Dad's  deep questions.  Two adults, two kids and three dogs in a small house subject to Montana winters. Cold snaps could be deep and long - a week or more with highs well below 0° F ( -18° C) weren't uncommon.  More impressive were the lows:  -30° F (-35°C) came at least once every Winter and record lows were below -40°.  Dressing for it was a necessary skill.  Inside the home my Dad controlled a powerful technology - the thermostat.

 

When people were around during daytime the thermostat was set to 62°.  The nighttime setting, from 9 PM until the first person got up at about 5:30AM,  was 55°   If people were out of the house  the setting was 52°.   As far as I could tell these were his fundamental constants.  Warm clothing, sweaters, quilts (my parents cheated and had an electric blanket)  made it comfortable and sometimes even too warm.  There was only one thermostat and a few areas of the house were always a bit colder or warmer.  The dogs found the warmest regions at dog level. They also had warm blankets that they'd drag around where needed.

 

Since then I've learned a bit about home heating.  Some of the best information on home energy measurements comes from England.  They found standard modern construction homes see seven to ten percent energy savings for each degree celsius drop between 15°  and 20° C .  Lowering the thermostat setting from 70°  to 61° (21° to 16° C) could translate to 30 to 40% reduction in your heating bill.  It could also make a serious impact in places facing severe gas shortages this coming Winter.  

 

There are other tricks.  A big key is to heat the people and not the airspace where they aren't.  We had a small, partly finished family room in the basement.  We were there a lot during the Winter as it was the warmest room in the house.  Four people and three dogs radiated body heat along with four 150 watt lamps in the ceiling and a small electric heater (pro tip -- if you have a male dog, don't put one of these on the floor).  My Dad had a tendency to drop the thermostat to nighttime levels when we were down there. Most of our books lived there and a long work bench allowed my sister and I to work on homework and hobbies.  There was a TV, but it didn't get used that much.  It's where we told stories.¹  In the Summer the warm rugs on the floor came up and the room was a naturally cool place to escape the heat of the un-airconditioned home.  

 

The English studies I came across note the average English home was heated to 13° C (55° F) in 1970 rising to 20° C by 2000.   Our house wasn't all that different from the average English house. 

 

There are many other tricks for saving energy - insulation, heat pumps and so on, but they won't happen in Europe before this Winter for most people.  Insulation, done improperly, can be a two edged sword.  Forced air heating, the most common type in the US, fills the house with heated air. Insulation keeps as much of the heat as possible inside.  The problem is that often the air is trapped inside.  Stale air can be unhealthy (VoCs, high CO₂ levels, etc.).  There's a simple technology that can help - in fact you needn't look farther than your nose.  Your nose is a heat exchanger.  Cold air comes in and is heated up without releasing much of your body heat when you exhale.  Most industrial buildings and some homes have heat exchangers - they're required by many building codes to keep super insulated homes healthy.  Something to look into if your place is heavily insulated.

 

Localized radiant heat allows you to circulate some air from the outside and still be comfortable - you're heating people rather than the air.  You've probably noticed Scrooge's chair,  in many adaptations of A Christmas Carol, has a high back curved sides.  These were common in the Victorian era.. sit in front of a fireplace and focus the warmth. People have experimented with heated chairs with good results - notably work at Berkeley in the past decade.²  (They also designed and tested cooled chairs for the Summer).  People who live on the Japanese island of Hokkaidō modify the short legged Japanese family tables by putting a blanket over them and a small heater underneath.  I've used one of these visiting a couple from Sapporo when they were living in NY and was amazed how well it worked in their otherwise chilly house.  Teenagers like them for other reasons when their parents aren't home.  

 

In short there are many paths to clever - no silver bullets, but a lot of silver buckshot.  Twenty or thirty percent conversation levels are quite realistic for many people.   I won't mention adventures in an unheated 15 foot trailer with three dogs at -25°F (my mother thought colder temperatures were dangerous)

¹  Nordic families seemed to tell a lot of stories.  Our heritage isn't Nordic, but many of our neighbors were and some of that rubbed off on us. 

² Here's an example and test of a heated/cooled chair. You could make one of these.. I haven't seen anything commercial.

 

 

 

where nobody is average

The first military airplanes designed after WWII began to arrive in the late 1940s.  A number of these early jets were more complicated to fly and the number of incidents and accidents alarmed the military.  Incidents where something went wrong, but the pilot and aircraft came back safely, and accidents were more serious.  As the jets were mechanically more reliable than their piston powered WWII era cousins, it only seemed natural to blame pilot error.

 

A  few remarkable pilots would find themselves in a bad spot, but always manage to get themselves out of trouble - often saving the aircraft.  Chuck Yeager was the legendary master  and was sent to airbases to show pilots how to fly correctly.  But the fact was this was happening to very skilled pilots.  With pilot error and aircraft malfunction seen as less likely root causes, eventually cockpit design was questioned.

 

Military airplane cockpit measurements were based on an average of a few measurements of about a hundred airmen in the mid 1920s. Improved nutrition and larger pilots was suspected as changing the average, so a massive study was undertaken that took 140 measurements of nearly 4,100 pilots.  In theory this would lead to a better average cockpit.

 

Gilbert Daniels joined the medical division at Wright Patterson out of college and was one of the people tasked with making these measurements and coming up with averages.  It turned out he was biased.  In college he did some research trying to find an average hand size and found it impossible.  Sifting through the data he looked at ten measurements deemed most important for the cockpit and calculated an average range for each that included 30 percent of the measurements - a nice wide average.  The surprise was than none of the pilots fell within all ten of the wide averages.  Gilbert found if you picked any three of the ten, less than four percent of the pilots would be average.  No one was average.

 

It shouldn't have been a surprise. Women's clothing designers had known it for awhile - something attributed to women being "different."  Eventually the military believed Gilbert's work and mandated highly adjustable cockpits.  All new aircraft had to be adjustable for males in the 5 to 95 percentiles for each of about ten critical dimensions.  Airplane manufactures balked - "it can't be done",  but finally came around because .. well .. contracts.

 

The fifties saw more adjustability come to automotive interiors, but at a much slower and more incomplete pace than military aviation.  About ten years ago I found myself driving a friend's Japanese sports car on the Pacific Coast Highway.  A lovely car considered one of the best handling in the world, but I didn't fit - there was no way to adjust the seat or steering wheel enough.  I'm not particularly tall, but have short legs and a long torso.  I also have very long feet (in theory the right dimensions for a swimmer, but not my thing).  A few months later I was helping a friend move in a rented truck.  The same problem.  There weren't enough adjustments to prevent my feet from getting caught near the pedals.  And then there's automobile safety.  The instrumented dummies used in crash tests cover less than a quarter of adults bringing into question the tests themselves.  

 

And it's not just physical differences.  'What color is the dress?' became a popular question as people legitimately came to different conclusions.  Tonal language native speakers are much more likely than other populations to have "perfect pitch."  Some people are purely visual thinkers, but most are a mixture of audio and visual.  There are people with very poor stereo vision - I know one who is an animator.   Increasingly "on the spectrum" is a meaningless construct.  Our brains have so many differences - so many dimensions - that it's likely none of us are truly "normal."  This has become an issue in fMRI studies recently. For example studies showing differences between men and women are often in the noise and meaningless. The field will eventually get more rigor.  You really need to know what dimension you're measuring.

 

Finally there's neuroplasticity.  We know that kids undergo huge changes in neural connectivity as they grow and some areas of the brain aren't stable until the mid 20s.  (I have a neurological condition that is believed to have resulted from an incomplete severing of neural connections when I was a baby.  It isn't a big thing, but is different enough to be worthy of study).  One seen as stopping around 30, neuroplasticity is seen throughout life, albeit at different rates.  There are examples of dramatic repurposing of regions of the brain.  Helen Santoro's missing left temporal lobe is one of the more dramatic examples.

 

Differences are a feature.

 

 

 

design for kids and community in japan

a minipost

 

About twenty years ago I was associated with a human computer interface department. A good deal of the work was associated with this nebulous concept of “community”. The term tends to be defined in the mind of the person talking about it .. like the word god. We had a list of about twenty words that needed rigorous contest when we publishing internally or externally .. community was everyone’s first choice for the list, That said most of us default to a warm and fuzzy concept. How people and neighborhoods should interact. The sort of thing Bob Kraut worries about. (to be fair he also thinks about communities like QAnon)

 

A recent 99% Invisible podcast focused on Japanese community of place design.. deign for the six year old Mixed use zoning, very narrow roads, a school house at the center and very independent kids. Some of us worry about urban and suburban design and traffic - how to you minimize the two or three ton vehicle carrying a driver and a bag of groceries? We often look to the Netherlands snd the Nordics for inspiration Indeed they’re excellent examples of moving from 1970s car-centric design to something better for cyclists and pedestrians. Japan offers a different path - one that seems unlikely in the US.

 

Here’s the a link to the audio, a transcript and a few videos

 

A comment .. most of us of a certain age grew up with kids walking and cycling everywhere - starting around six for walking and seven or eight for cycling. It was the only way a kid could deal with the scale of suburban design with fixed zoning and wide roads. That’s the environment the Dutch and Nordics started with rather than doubling down on complete car dependance.
