Hmm, manmade microclimates. 

We have them naturally in San Diego, explained here:

and here
http://www.hribar.com/san-diego-microclimate.html

I love it! I live in a perfect climate zone (Mission Valley), it's own 
intermediate microclimate in between coastal, which can actually be 
surprisingly cool even in summer and the MUCH TOO HOT inland areas. When I 
listen to the news I know how to adjust and prepare.

Subject: Measuring the Microclimate in Manhattan, NYC (Sorry Kansas)
From: "Mike Palij" 
Date: Wed, 27 Aug 2014 11:52:02 -0400


Our colleagues at the City College of the City University of New York (CUNY) 
are doing a research study on the differences in climate measures (e.g., 
temperature, humidity, etc.) on a block by block basis in Manhattan.  Though 
the research results have not yet been formally published, preliminary results 
confirm informal observation: temperature in Manhattan varies systematically as 
a function of location.
"Low lying" areas of Manhattan, such as the Lower East Side (LES) tend to be 
hotter than "higher elevations".

NOTE: Some might think of Manhattan as being flat but this is a mistake.  The 
highest "natural" point in Manhattan is 265.05 feet above sea level in Bennett 
Park in northern Manhattan, above the GW bridge; see the NYC Parks website:
http://www.nycgovparks.org/parks/bennett-park/monuments/721
Some may sneer at a height that is less than a vertical football field but 
others may consider it a blessing especially if you bike around Manhattan.  
Indeed, "bikers" provide fairly detailed info about elevation in Manhattan; see:
http://www.bikeforums.net/northeast/303521-manhattan-nyc-elevation-meters-above-sea-level.html
Using the above info, one can predict which areas in Manhattan were most 
affected by Superstorm Sandy. 
Anyway, the local public radio station WNYC had a news piece on the study (see:
http://www.wnyc.org/story/beware-light-box-effect-and-other-secrets-nycs-microclimates/)
which was picked up the Gothamist; see:
http://gothamist.com/2014/08/26/temperatures_in_manhattan_do_actual.php
And here is the website for the City College research group:
http://http://glasslab.engr.ccny.cuny.edu/u/brianvh/UHI/
There's a real 1990s vibe to the research website. ;-)

Now, it probably should not come as a big surprise the there are systematic 
differences in temperatures on different blocks or, more accurately, 
streets/avenues.  For example, most streets run east-west which means that the 
amount of sunlight they get during the day is limited -- trees further reduce 
the amount of direct sunlight on pavement and sidewalks.  All avenues run 
north-south and these receive the greatest amount of sunlight during the day.  
Temps on avenues are typically higher than on streets and one explanation is 
because of the sunlight they receive. However, there are other factors to 
consider:
(1)  Avenues tend to have the greatest amount of traffic, mostly of the stop 
and go kind which would add to the heating of the surface
(2) Underground power lines, steam pipes, and telecommunications cables also 
use the avenue to reach neighborhoods.  All of these generate heat
(3)  Many subways run under avenue, with the older IRT and BMT lines (from the 
early 20th century) near to the surface.  These were usually constructed using 
the "cut and cover" method which involved digging an open ditch to the level of 
the subway and then covering it up (the IND line which was created in the 1930s 
typically used deep tunneling to cut done on the "collateral damage" caused by 
the cut and cover method).
And so on.  Remember when you're next in NYC:  some parts are hotter than 
others. ;-)

Re:[tips] Teaching and Learning

[Richard Hake]

Some subscribers to TIPS might be interested in a discussion list post "Re: 
Teaching and Learning" [Hake (2014)].  The abstract reads:



ABSTRACT: GS Chandy (2014) in his Math-Teach post titled "Re: Khan Academy 2.0" 
at  wrote: "At its core, teaching has to be about 
helping the student to learn."

 To which math education guru Robert Hansen responded at 
: "teaching is about teaching things. That is pedagogy. 
In an ideal world, every student would be able to learn every thing the teacher 
teaches. It is only (relatively) recently that teaching took on the role of 
learning, or better known as remediation, and quite frankly, not only does it 
suck at it, the more you make teaching about learning, the less you make it 
about teaching, until such point, it isn't about teaching at all. Or learning."

 For a more informed view of the relationship of teaching to learning see 
">From Teaching to Learning: A New Paradigm for Undergraduate Education" ]Barr 
& Tagg (1995)] at . They wrote: "A paradigm shift is 
taking hold in American higher education. In its briefest form, the paradigm 
that has governed our colleges is this: A college is an institution that exists 
*to provide instruction*. Subtly but profoundly we are shifting to a new 
paradigm: A college is an institution that exists *to produce learning*. This 
shift changes everything. It is both needed and wanted."
