Canadian culture, social studies: Canadian ethnicity

Tutoring social studies, ethnicity may arise. The tutor brings up an example he observed.

In the Fraser Valley last week, I was leaving a hotel lobby to return to the room. The night air felt brisk on the face; snow or rain may have been falling.

Feeling the cold’s sharpness, I was hurrying to return indoors, but slowed to do a double-take. Twenty feet outside the main doors stood a tall man in cowboy hat and boots and a sports shirt. Behind him, a pickup truck idled; on its other side stood his friend, dressed similarly.

By their posture, the two men were in their twenties. I could tell they are taller than I am, and fit. Neither wore a coat, nor were they in any hurry to enter the hotel. They looked at me, in my quilted bright orange winter jacket, as if I’m from the moon. Then they resumed talking.

“They must be from Alberta,” I realized. Glancing at their license plate, I saw red numbers.

Sometimes it might take a Canadian to know another one. Furthermore, Canada is big enough – and old enough – to have its own distinct ethnicities. The ability of those Albertans to cross the Rockies, then stand in a Fraser Valley parking lot like it’s their backyard, is delightful.

Happy holidays:)

Math: minimum sum of squares

Tutoring math, you encounter patterns. The tutor brings up one about sums of squares.

If two whole numbers sum to a constant even one, then their minimum sum of squares will come from each being half. The reason:

Let the numbers sum to 2n, and let the numbers then be n-k and n+k. Then the sum of their squares is

(n-k)2 + (n+k)2

Expanding each square, we get

n2-2nk+k2 + n2+2nk+k2=2n2+2k2

Therefore, the minimum sum of squares will be achieved when k=0, that is, when n-k=n+k=n.

Anthropology: organic solidarity

Tutoring anthropology, the cohesion of a society is an important concept. The tutor defines organic solidarity.

organic solidarity:

cohesion achieved in a complex society wherein work is specialized to the extent that one worker cannot perform the duties of someone in a different job. For instance, an electrician cannot be replaced by a teacher.

In a society with organic solidarity, the typical worker cannot meet their survival needs without trading. Since the workers of different professions all need each other to survive, cohesion is achieved.

Anthropology: mechanical solidarity

Tutoring social sciences, definitions are important. The tutor begins about mechanical solidarity.

mechanical solidarity:
Similarity among people such that everyone understands each other’s jobs. Furthermore, the society’s technology is commonly understood – and even reproducible – by its members.

A society with mechanical solidarity is unified by the shared reality of all its members. Hunter-gatherer societies, as well as stone-age farming ones before large-scale irrigation, had mechanical solidarity.

Philosophy, Religion: how to achieve a perfect life

For me, religion involves constant self-tutoring. The tutor shares an observation from Abhay Charanaravinda Bhaktivedanta Swami Prabhupada, founder of the Hare Krishna Movement.

At this festive time, people are striving to keep their relationships strong. During the year’s darkest days, doing so makes sense: humans survive by relationships, and they love the light.

I think we live in a wise era: virtually everyone I hear wants something immaterial, be it relationship to God or to other people.

Whether you are surrounded by people in bright festivity, or alone in a room lighted only by the computer screen, does the following observation intrigue you?

If you understand what is God and try to love Him, your life is perfect.

-Abhay Charanaravinda Bhaktivedanta Swami Prabhupada

Happy holidays:)

Cholesterol: hdl vs ldl

More lifestyle tutoring: the tutor continues to research cholesterol.

Perhaps many of us have heard that HDL is the “good” cholesterol, while LDL is the “bad”. What’s the difference?

HDL: collects cholesterol from the blood and conveys it to the liver, where it will be cleansed from the body.

LDL: conveys cholesterol to an artery, where it may be deposited to form plaque. As a result, the artery wall thickens, while its room for blood passage decreases.

Lifestyle: Shaw remote replacement

Lifestyle, for me, means constant self-tutoring. The tutor mentions a good experience with Shaw Cable.

My family loves TV. Eventually, after so much use, the Shaw remote wore out. Some buttons, in the end, were very difficult to activate. Watching my wife struggle the other night, I decided to act.

I always try Shaw Chat first – it’s, in my experience, very quick and convenient. I waited only sixteen seconds to reach an operator. Geoffrey confirmed that I could just bring the worn-out remote to the Shaw store and they would replace it over the counter. The new one even includes batteries:)

Kim, at the counter, handed me the new remote and asked if I needed help with anything else. I said I was thinking about changing some packages to lower my bill but would happily do so online, at home.

“Let’s take a look,” she began. She immediately found some ways to save me money on the next bill and gave me other savings options to bring home for family approval.

Ten minutes after leaving my home, I was back with the new remote, anticipating a lower cable bill next month. Thanks, Shaw:)

Computer science: what is a namespace?

Tutoring computer science, terms are so important. The tutor defines namespace.

A labeled data structure that can contain its own definitions of variables, functions, files, etc.

An example of a namespace is a directory (aka, folder). Imagine two different folders – Folder0 and Folder1. Further, let’s imagine each contains a file named file-x, but the file-x in Folder0 is different from that in Folder1. Such a situation is possible because the full names of the two versions of file-x are different: one is Folder0/file-x, while the other is Folder1/file-x. We could also say that one version of file-x is from the Folder0 namespace, while the other exists in the Folder1 namespace.

Lifestyle: cooking: substitute for baking powder

For me, learning to cook means constant self-tutoring. The tutor tells of a substitute he used, successfully, for baking power.

Last night, I planned “breakfast for dinner”: pancakes. However, the recipe I wanted to use calls for two teaspoons baking powder; at best I had only one left. My wife said the store was crazy busy, so I had to improvise.

I surfed to, where I learned of ten possible substitutes for baking powder. I chose to use 1/4 tsp baking soda plus 1/2 tsp vinegar.

I added the baking soda to the dry ingredients, then, at the last instant, added the vinegar to the mix of egg, milk and oil. Next I mixed the wet and dry ingredients as indicated (making a well in the dry, pouring the wet in).

I was afraid the pancakes might taste of vinegar, but even my wife says they’re fine. No one complained.
