The New Colossus

Statue of Liberty - Liberty Enlightening the World

by Emma Lazarus

Not like the brazen giant of Greek fame,
With conquering limbs astride from land to land;
Here at our sea-washed, sunset gates shall stand
A mighty woman with a torch, whose flame
Is the imprisoned lightning, and her name
Mother of Exiles. From her beacon-hand
Glows world-wide welcome; her mild eyes command
The air-bridged harbor that twin cities frame.
“Keep, ancient lands, your storied pomp!” cries she
With silent lips. “Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tost to me,
I lift my lamp beside the golden door!”


The Wild Canadian Year

Spring

THE WILD CANADIAN YEAR begins with SPRING — a dazzling cinematic journey across the country revealing remarkable never-before-filmed wildlife behaviour and spectacular Canadian landscapes.

March 21st is the first day of spring all across Canada. Life is on the move again, as the whole country begins stirring after the long cold days of winter.

In northern Quebec, the female caribou of the Leaf River herd are on epic 600-kilometre migration to reach their calving grounds. They are racing against the clock to complete their journey before the spring melt begins. Along the way, they must face off against an ancient adversary that hounds them their entire lives – wolves.

Spring is a time of transformation. On the Hay River in the Northwest Territories, 3.5 million tons of ice suddenly breaks free and plows downstream, roaring over a 30-metre waterfall as the river undergoes a thunderous metamorphosis.

One of the most astonishing of all transformations is that of the wood frog. Deep beneath the leaf litter, wood frogs spend the winter frozen solid, suspended somewhere between life and death. Macro time-lapse photography reveals its heart beating for the first time in six months.

The return of migrating animals is another harbinger of the season. The calliope hummingbird — one of Canada’s smallest birds — returns from Mexico to build her egg cup sized nest. And magnificent white pelicans return to their breeding colony on Last Mountain Lake in southern Saskatchewan, where the pelicans fish together using their own form of synchronized swimming to help them bag a big one.

Spring is also the season of birth and new life. From boisterous Arctic fox puppies taking their first steps, to playful East Coast black bear cubs learning to climb trees, to curious sea otter pups rafting in kelp fronds and riding on their mother’s bellies, SPRING offers an intimate and heart-warming look at the lives of these young creatures as they learn to navigate the challenges of life in the wild.

SPRING brings viewers a new story about a unique subspecies of wolves known as sea wolves. These resourceful wolves were filmed, for the first time, hunting sea otters.

SPRING is a unique and important season and this episode of THE WILD CANADIAN YEAR introduces an amazing variety of wildlife characters, all captured in exquisite 4K ultra-high definition. This spectacular journey through the season will take viewers on wildlife adventure unlike any other.

Summer

Summer is the second chapter in the spectacular landmark series THE WILD CANADIAN YEAR, revealing dramatic wildlife stories and showcasing Canadian landscapes at the peak of their splendour.

The journey begins in the offshore waters off the Pacific Coast of Canada, where four thousand Steller sea lion pups have just been born on a remote island. The boisterous sea lion pups are facing the danger of swimming in rough seas – but an even greater threat is lurking in the water — killer whales. An incredible hunt unfolds when a family of killer whales launches a stealth attack on the sea lions.

West of the sea lion rookery, we dive beneath the waves to meet blue sharks, huge stinging jellyfish, and a bizarre-looking fish the size of a pickup truck — the mola mola. These warm-water loving creatures are following seasonal currents that swing closer to Canadian shores in summer.

Summer is a season when young animals are on a steep learning curve. Their parents must shepherd them through the first trials of life, and teach them to master the skills they will need to survive on their own. In the Badlands, a mother golden eagle risks her life to defend her chick from a violent thunderstorm, and in the Columbia Mountains, mountain goat moms watch as their kids get to practice their fancy footwork on vertical cliffs as they make their first trip to a mineral lick.

Summer is also the best season to experience some unique seasonal landscapes. In southern BC, in Canadas only true desert, a bizarre Spotted Lake emerges in summer. As the sun evaporates the lake water, highly concentrated minerals are exposed, creating a stunning mosaic of yellow, white and green ponds. And in northern Saskatchewan, summer weather helps shape the extraordinary Athabasca Sand Dunes, a vast swath of sand covering 50 thousand hectares in the middle of the boreal forest. This mini-Sahara has seldom been filmed before.

In the Arctic polar bears and three thousand beluga whales converge around the mouth of a river emptying into Hudson Bay. The whales have come here to give birth to their young in the warm, sheltered waters — but for the bears this is a unique hunting opportunity. Only a few, 500-kilo polar bears have learnt a daring hunting technique never before captured on film.

Revealing incredible landscapes, extreme weather, and dramatic behaviour in the lives of Canadas most iconic wildlife, summer is an exciting and intense chapter in The Wild Canadian Year. All captured in stunning 4K ultra-high definition, our journey through summer reveals the season as never seen before.

Fall

Fall, the third episode of THE WILD CANADIAN YEAR, chronicles a remarkable season of change when the great Canadian wilderness is transformed by bursts of spectacular colours, and magical forests of mushrooms emerge beneath the forest canopy.

Fall is a time of great migrations — three-quarters of all of Canada’s bird species fly south. On the vast tidal flats of the world-famous Bay of Fundy, massive flocks of semipalmated sandpipers feast and gather strength for their epic journey south. The world’s biggest tides provide an all-you-can-eat buffet for the hungry travellers, but as the waters rise, the resting hordes become targets for swift and powerful hunters: peregrine falcons. The sandpipers rise up in swirling, ever-shifting giant flocks that confuse the falcons. But the falcons have a hunting strategy that rarely fails.

With the harsh winter weather ahead, Fall is a critical time to prepare. The appearance of acorns and hazelnuts in the eastern woodlands send chipmunks, Canada’s master hoarders, into overdrive. With the seasonal clock ticking, they must race to gather winter supplies — and protect them from cheeky — and sticky-fingered — rivals.

Further west, the majestic Rocky Mountains provide a spectacular backdrop for an extraordinary seasonal courtship. Fall is the time of the rut for the continent’s largest deer species — moose. They engage in an intimate mating ritual, a tender encounter rarely seen between two titans of the North.

Beneath the turbulent waters of the rugged BC coast in the wild Canadian Fall, the giant Pacific octopus, the largest of its kind, broods her clutch of 80,000 eggs. The female octopus has spent the past 6 months tending her eggs and in the end, makes the ultimate sacrifice to ensure her young’s survival. Also, in the seasonless depths of the Pacific, ancient enemies, the leather sea star and swimming anemone, engage in a bizarre and compelling dance between predator and prey.

For northern gannet chicks, fall is the season for a dangerous rite of passage. On the eastern edge of Newfoundland, thousands of young gannets cling to the cliffs. But it’s time for them to leave the safety of the nest and leap into the abyss. To reach the cliff edge they must run a deadly gauntlet of territorial, and fiercely aggressive, neighbours.

In Fall, every wild inhabitant of Canada knows it’s a brief but pivotal moment before winter arrives to The Wild Canadian Year.

Winter

THE WILD CANADIAN YEAR’s fourth episode — Winter — reveals stories from the harshest time of year, as Canada’s landscapes are transformed by the cruel and dramatic beauty of snow and ice. For all wild animals, it’s a challenge to adapt to winter’s harsh conditions.

Winter weather creates severe conditions across the country, including one of Canada’s most remote and far-flung islands — a crescent-shaped sliver of land 300 kilometres off the coast of Nova Scotia: Sable Island. Here 400,000 grey seals have come ashore to give birth and mate. The tiny seal pups are born into a world of howling, gale-force winds, blowing sand, and blizzards. Living alongside them are the remarkable wild horses of Sable Island.

Although harsh, winter is also a beautiful season. In the Arctic, the sun sets and will not rise again for months, and the spectacular purple and green dance of the aurora borealis fills the night skies.

Finding food is a challenge at this time of year. In central Saskatchewan, sleek river otters punch through the ice to go hunting in the icy depths; in northern Quebec, barren ground caribou dig through a metres-thick blanket of snow to uncover tiny bits of a dry lichen, and on Prince Edward Island, a red fox relies on her keen sense of hearing to pinpoint the exact location of mice and voles moving beneath the snow and then dive after them nose-first.

While snow does make life harder for some it provides surprising protection for others. Meadow voles live in tunnels they burrow under the snow to escape the cold, and the attention of aerial hunters like grey owls. But there are slender hunters like the short-tailed weasel that can still hunt them through the tunnels of this subnivean world.

One of the more extreme strategies that animals have evolved to deal with severe conditions of winter is hibernation. In the boreal forests of Quebec, a mother black bear slumbers in a large underground chamber buried in many metres of snow. She has given birth to two tiny cubs. Bear mothers give birth to some of the smallest young in relation to their body size of any mammal, and the adorable cubs are barely larger than a squirrel.

Winter is the longest season in Canada. In the north, it lasts for half the year or more. And a few lucky species are supremely adapted to it. In the shadows of the Yukon forest, the elusive Canadian lynx use their huge snowshoe-shaped paws to glide silently across the snow, stealthily manoeuvring through the woods to hunt snowshoe hares — an event never before filmed in the wild. Wolves too thrive in winter. In northern Quebec packs of wolves hunt the barren ground caribou as they struggle to find food in the deep snow of the northern boreal forest.

Winter introduces an amazing array of animal characters and opens a window onto the most intimate and dramatic moments of their lives. It is the make or break season for most animals — filled with drama, excitement, hardship and wonder. Winter offers a spectacular journey through the season that will take you on a wildlife adventure unlike any other.


Bach and the Sentry

by Ivor Gurney

Watching the dark my spirit rose in flood
  On that most dearest Prelude of my delight.
The low-lying mist lifted its hood,
  The October stars showed nobly in clear night.

When I return, and to real music-making,
  And play that Prelude, how will it happen then?
Shall I feel as I felt, a sentry hardly waking,
  With a dull sense of No Man’s Land again?


When I am dead, my dearest

by Christina Rossetti

When I am dead, my dearest,
Sing no sad songs for me;
Plant thou no roses at my head,
Nor shady cypress tree:
Be the green grass above me
With showers and dewdrops wet;
And if thou wilt, remember,
And if thou wilt, forget.

I shall not see the shadows,
I shall not feel the rain;
I shall not hear the nightingale
Sing on, as if in pain:
And dreaming through the twilight
That doth not rise nor set,
Haply I may remember,
And haply may forget.

The Road Not Taken

by Robert Frost

Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;

Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,

And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.


How to read music - Tim Hansen - TED-Ed - Transcript

When we watch a film or a play, we know that the actors probably learned their lines from a script, which essentially tells them what to say and when to say it. A piece of written music operates on exactly the same principle. In a very basic sense, it tells a performer what to play and when to play it. Aesthetically speaking, there’s a world of difference between, say, Beethoven and Justin Bieber, but both artists have used the same building blocks to create their music: notes. And although the end result can sound quite complicated, the logic behind musical notes is actually pretty straightforward. Let’s take a look at the foundational elements to music notation and how they interact to create a work of art. Music is written on five parallel lines that go across the page. These five lines are called a staff, and a staff operates on two axes: up and down and left to right. The up-and-down axis tells the performer the pitch of the note or what note to play, and the left-to-right axis tells the performer the rhythm of the note or when to play it. Let’s start with pitch. To help us out, we’re going to use a piano, but this system works for pretty much any instrument you can think of. In the Western music tradition, pitches are named after the first seven letters of the alphabet, A, B, C, D, E, F, and G. After that, the cycle repeats itself: A, B, C, D, E, F, G, A, B, C, D, E, F, G, and so on. But how do these pitches get their names? Well, for example, if you played an F and then played another F higher or lower on the piano, you’d notice that they sound pretty similar compared to, say, a B. Going back to the staff, every line and every space between two lines represents a separate pitch. If we put a note on one of these lines or one of these spaces, we’re telling a performer to play that pitch. The higher up on the staff a note is placed, the higher the pitch. But there are obviously many, many more pitches than the nine that these lines and spaces gives us. A grand piano, for example, can play 88 separate notes. So how do we condense 88 notes onto a single staff? We use something called a clef, a weird-looking figure placed at the beginning of the staff, which acts like a reference point, telling you that a particular line or space corresponds to a specific note on your instrument. If we want to play notes that aren’t on the staff, we kind of cheat and draw extra little lines called ledger lines and place the notes on them. If we have to draw so many ledger lines that it gets confusing, then we need to change to a different clef. As for telling a performer when to play the notes, two main elements control this: the beat and the rhythm. The beat of a piece of music is, by itself, kind of boring. It sounds like this. (Ticking) Notice that it doesn’t change, it just plugs along quite happily. It can go slow or fast or whatever you like, really. The point is that just like the second hand on a clock divides one minute into sixty seconds, with each second just as long as every other second, the beat divides a piece of music into little fragments of time that are all the same length: beats. With a steady beat as a foundation, we can add rhythm to our pitches, and that’s when music really starts to happen. This is a quarter note. It’s the most basic unit of rhythm, and it’s worth one beat. This is a half note, and it’s worth two beats. This whole note here is worth four beats, and these little guys are eighth notes, worth half a beat each. “Great,” you say, “what does that mean?” You might have noticed that across the length of a staff, there are little lines dividing it into small sections. These are bar lines and we refer to each section as a bar. At the beginning of a piece of music, just after the clef, is something called the time signature, which tells a performer how many beats are in each bar. This says there are two beats in each bar, this says there are three, this one four, and so on. The bottom number tells us what kind of note is to be used as the basic unit for the beat. One corresponds to a whole note, two to a half note, four to a quarter note, and eight to an eighth note, and so on. So this time signature here tells us that there are four quarter notes in each bar, one, two, three, four; one, two, three, four, and so on. But like I said before, if we just stick to the beat, it gets kind of boring, so we’ll replace some quarter notes with different rhythms. Notice that even though the number of notes in each bar has changed, the total number of beats in each bar hasn’t. So, what does our musical creation sound like? (Music) Eh, sounds okay, but maybe a bit thin, right? Let’s add another instrument with its own pitch and rhythm. Now it’s sounding like music. Sure, it takes some practice to get used to reading it quickly and playing what we see on our instrument, but, with a bit of time and patience, you could be the next Beethoven or Justin Bieber.

Social norms in Canada

Saying Hi!

Make an attempt at small talk with people around you! The easiest way to make connections with neighbours and community is just to talk to everyone & introduce yourself!

Eye Contact

It is customary for Canadians to make eye contact with the person they are talking to, no matter their gender, age or if they are an authority figure, such as a professor or supervisor.

Say Sorry

Canadians say sorry all the time, to everyone, even if it’s not their fault, even if nothing a person does might be considered worthy of saying “sorry” - Canadians will say sorry!

Be On Time

Better be there on time! A habit that many Canadians get into is arriving 15 minutes early to a scheduled event, showing up early shows professionalism - you’re prepared and ready to work.

People expect you to be on time for work, school, medical appointments, and business meetings. You could lose your job or be suspended from school if you are frequently late. People will not wait for more than 10 - 15 minutes for someone late for a business meeting. If you are running late, make sure to contact the person you are meeting, and explain why you are late. For social events, it is expected people arrive on time, up to and no later than half an hour from the time they were invited.

Talk In A Reasonable Range With People

In North America, personal boundaries are essential, and respecting them is even more critical. Talking too close to people can throw off the person who isn’t used to it; some people view it as intimidating, while others just find it awkward. Standing too close isn’t that big of an issue - usually, people will back up to a comfortable distance if they feel you’re too close - but it can contribute to leaving a wrong impression overall when meeting someone for the first time or networking.

When Canadians go to the pharmacy, they stand at least 100 cm away from the person served at the counter. Standing any closer makes Canadians feel uncomfortable - especially in the pharmacy, people think the information they are sharing with the pharmacist is private and therefore gives a significant amount of distance between the customer being served and the person next in line.

Be Courteous On The Bus

say thank you to the bus driver when getting off the bus

Be Inclusive!

Canada is a very diverse place, with many different viewpoints and cultures mixed together. In Canada, though we may disagree with each other’s opinions or lifestyles, it is important to respect everyone regardless of your views. Discrimination or prejudice based on race, sex, religion, or sexual orientation will likely be met with hostility - Canadians strive for politeness.

Hold The Door!

Holding the door open for people is a fundamental part of good manners in Canada.

Do NOT Kiss On The Cheek

just put your hand out to shake

When introduced, Canadians smile and say, “Hello, how are you?” or “Hello, nice to meet you!” It is customary to extend your right hand to shake. To shake hands, grip the other person’s hand firmly but not tightly, and gently pump two to three times.

Personal questions

Unless you are with a friend, it is impolite to ask the following personal questions:

  • How much money do you make?
  • How much did you pay for your house/car?
  • Why aren’t you married?
  • Why don’t you have children?
  • How old are you?
  • How much do you weigh?

Public Behaviour

Loud conversations, name-calling or violence (such as spanking children) are not acceptable. Hitting or threatening another person, including family members, is against the law.

Lineups

Canadians line up at bus stops, banks, stores, restaurants, markets, events, cinema etc. Canadian expect services on a first-come, first-served basis. If there is no lineup, Canadians take turns instead of pushing ahead. People will become angry if you cut into the middle of a line, instead of lining up from the back, or if you push against the person ahead of you.

Holding Hands

Men and women, young children and family members often hold hands in public. It is also acceptable for two men or two women to hold hands.

Respect the environment

Canadians are very proud of our beautiful landscape and are very environmentally conscious. It is expected people do not litter, or leave garbage in the street, on the ground, or throw litter out a car. You can be fined for littering. You are expected to put your trash in the public garbage cans available in most public places.

Smoking

Smoking is not permitted in any public or workplace, including restaurants, bus or taxi shelters (indoor AND outdoor), public vehicles and washrooms. If you smoke, you are not allowed within five meters from the doorway, window or air intake of public or workplace. Ask permission before lighting a cigarette in someone’s home or car.

Volunteer

Volunteering is a great way to get to know the people in your community. Becoming a volunteer is a great way to build skills for future employment in Canada!
