Green Green 13uncensored

Blue or green like a tangerine with stories


few weeks ago I went to see a show of my dance teacher, Cecilia and Joao Colacrai Costa: "Blue as uma laranja ." Trying to document photographically this post, I found the blog of the piece as uma laranja Blue "and it found some pictures of the piece made by Yoana . I chose one of them because I wanted that you could receive an instant the scene, but I encourage everyone to continue watching the other snapshots you will find in this blog.

Maybe today surprise you want to talk about dance and shows ... Do you change the Mandarin Newton by Tangerine red shoes? And while this Mandarina comes from dancer, this is not the answer. Today I want to dance and Cecilia for the movement, space and time are the protagonists of any dance. They are so artistic, as Newtonian or even Einsteinian .

Have you noticed the words? It maybe that, just a combinatorial sounds and spellings, but that lead us to the variables involved in the equations of motion or Newton's equations. Space, the Latin spatium , where they are located objects, or distance traveled by a mobile at a certain time. Time physical scale that measures the duration or separation of events subject to change. Speed \u200b\u200bis the physical quantity expressing the change of position or space, depending on the time:

\vec v = \frac{\Delta \vec x}{\Delta t} = \frac{\vec x_f -\vec x_i}{t_f-t_i}

Acceleration is the change in velocity with time!

 a= \frac{v-v_0}{t-t_0} = \frac{\Delta v}{\Delta t}

And with this we already have all the ingredients to compose space. This is one of the most heard expressions on the kinds of Cecilia ... " Compose space! " And it is that physics, science is not free or beauty or subtlety ... or is stored in the textbooks. Physics is in every corner of the planet, in every action of life and at every turn of an orange. Science is everything and is nothing ... is only one way to look at the world and an attempt to explain what we have seen. Cecilia

reminds us to think about the millions of addresses that cross us, reminds us that the arms have intent ... Do you know what we talking about? Vector! Cecilia vector calculus does every time the queue is attached and moves gracefully around the room, Cecilia vector calculus does every time he walks and buy an orange. A vector is nothing more than a physical quantity with a length (a measure, or number of steps you walk), address (a fastball that moves) and effect (whether up or down the street, if walk to the right or left, look to where your nose) defined.

Not to mention the moment of inertia or rotational inertia. The moment of inertia is a scalar quantity, expressed with a single number (not as vectors that need for more information) that reflects the mass distribution of a body or system of particles rotating with the axis of rotation. The moment of inertia only depends on the geometry or shape of the body and the position of the axis of rotation. A dancer has more inertia by extending its arms to the side and therefore turn more slowly. If, however, contracts or arms rises, its mass gets closer to its center and therefore the center of rotation, and thereby reduces the moment of inertia, the resistance to rotation and increase its speed rotation.

We came a new term: the center ... Cecilia would insist ... " not forget your center! ." And no wonder, and our center of mass behaves as if all the mass of our body was placed there. Do you remember the problems of physics at school? All particles were about specific ... And has anyone seen a point running, dancing or eating oranges? No! These points walkers, dancers and eating oranges were other things that approximations. Physics of bringing live art ... And so far not doing too badly. Most often, the mistake we make considering that a human is a cylinder is so small that it is not worth engaging in a million calculations and complications include all the details, if in the end, getting just seven days later, a result very close to the estimate.

You see? The dance is physical and chemical ... (Another day we can talk about the reactions that occurs in the body dance), and anatomy and biology and is everything and is nothing ... because the universe has no labels, and because the only thing that changes is the eye looks.

"We name things in an attempt to re-invent the world from their names. As if all things exist by definition. Each description is a potential suggestion. Language reveals ways in limits, cuts to classify and define the issues. The im-possibilities of language invites us to reflect on other stocks. So, we started to compose a path for everything. A turning point, a context where the object in question could live, exist. from point A minimum build their probabilities. Point by point. And probably likely to reach potential, balancing between fiction and what they insist to call reality. "

(These are the words of the show sheet ...)
