LIFE (KEITH RICHARDS) AND THE INFLUENCE OF SCIENCE TEACHERS ON 20th CENTURY MUSIC

With that weight off my mind, my work improved at Dartford Tech. I was even getting praise. Doris kept some of my reports: Geography 59%, a good exam result. History 63%, quite good work. But against the science subjects on the report sheet the form master put a single bracket that enclosed them all- there was no daylight between them for abjectness- and he wrote them all off with no improvement in mathematics, physics and chemistry. Engineering drawing was still rather beyond him. That report on science subjects contained the story of the big betrayal and of how I was turned from a reasonably compliant student into a school terrorist and a criminal, with a lively and lasting rage against authority. 


Imagine that this teacher would have been too good and he would have motivated him, making Keith believe that he had a future in Science or that the teacher would have been compassionate and passed Keith the exam. Thanks to the famous scholar failure, the big enemy of education, acording to politicians, Keith could become a great musician.
Keith was expelled from this school to an Art school, where he started playing guitar. Some day justice will be done with all the bad teachers that helped to decide vocations

EMPIRE FALLS (RICHARD RUSSO) AND THE PROBABILITY OF INDEPENDENT EVENTS

 “It could be a baby sister.”
His father chuckled, probably at Peanuts. “Mostly boys in our family.”
Then we’re due for a girl,” Miles said.
That’s not how it works. It’s not like flipping a coin.”
What’s it like, then?” It seemed to Miles that it was exactly like flipping a coin, and he didn’t see any reason to let his father skate on such dubious logic just because he was a grown-up.
Max studied him, grinning again, though Miles wished he wouldn’t. “It’s more like rolling dice,” he explained. “Except they don’t have numbers. There’s six sides to a cube, right? In our family ‘boy’ is written on about five sides of the cube. ‘Girl’ is only written on one. So, if you had to bet with your own money, which would you bet on?”
Miles did some calculations. After a minute he said, “How many kids does Uncle Pete have?” His father’s older brother had moved out west—to Phoenix, Arizona—two decades earlier.
Four,” said his father. “All boys.”
Miles nodded. “And you’ve got me.”
You’re a boy too, last time I looked.”
That’s five in a row,” Miles pointed out.
Outside, footsteps sounded on the back porch: Grace, returning from church. Both Miles and his father glanced up at the kitchen window when she passed. This week her bouts of morning sickness had been less severe, and while she wasn’t looking as radiantly beautiful as she had on Martha’s Vineyard, neither did she appear as frightened and despairing as when they’d first returned.
Girl was on the sixth side, right?”




Yes, that´s not how it works. The likelihood of having a boy or a girl is 50% and it doesn´t depend on neither the number of boys you had before nor the amount of them that your uncle has.
According to the law of large numbers, the number of sons will be very close to the number of daughters only if you had a considerable amount of children. But it has to be a huge figure so that the law works.
We all know examples of families with lots of boys since their parents were looking for having a daughter, and they ended up giving up.
Therefore, the chance for the family in the text to have a boy or a girl is 50%. Just like flipping a coin at random.

GROWING PAINS AND THE GALILEO´S EXPERIMENT IN PISA



Mike Seaver explains very well to Di Caprio. Probably the history of Pisa Tower it is false, but it is such a beautiful experiment that it would deserve to be truth. With a simple and charm experiment you can show that Aristotelian Physics was wrong

THE ASTRONOMER (WALT WHITMAN) AND LEGITIMACY PREDILECTIONS OF POETS

When I heard the learn’d astronomer, 
When the proofs, the figures, were ranged in columns before me, 
When I was shown the charts and diagrams, to add, divide, and measure them, 
When I sitting heard the astronomer where he lectured with much applause in the lecture-room, 
How soon unaccountable I became tired and sick, 
Till rising and gliding out I wander’d off by myself, 
In the mystical moist night-air, and from time to time, 

Look’d up in perfect silence at the stars.



To start the new year without being tired let´s do the comment to Aldous Huxley, who in Science and Literature wrote abput this poem:

For some people the contempaltion of scientific theories is an experience hardly less golden than the experience of being in love or looking at a sunset. Whitman wasn´t one of them. As a human being who enjoys and suffers, facts and Astronomic hypothesis kept him cool; he preferred silence and stars. In the case of a poet, this is a compeltely legitimacy predilection

LOGAN LUCKY (STEVEN SODERBERGH) AND THE EXPLOSION´S CHEMISTRY



Daniel Craig explains very well the chemical reaction, it´s clear that he has been James Bond. Because of scenes like this the pupils demand fireworks to the Chemical teachers when they go to the laboratory

NEAR TO THE WILD HEART (CLARICE LISPECTOR) AND TIMBRE OF SONIC WAVES

Joana remembered how once, a few months after she was married, she had tirned to her husband to ask him something. They were out. And before she´d even finished her sentence, to Octávio´s surprise, she had stopped- brow furrowed, gaze amused. Ah- she had realized- she´d just repeated one of the voices she´d heard so often when she was single, always vaguely perplexed. The voice of a young woman besides her man. As her own had rung out just then to Octávio: sharp, empty, soaring upwards, with identical, clear notes. Something unfinished, ecstatic, somewhat satiated. Trying to scream… Bright days, clear and dry, sexless day voice and days, choir boys in an outdoor mass. And something lost, heading for mild despair… That newlywed timbre had a history, a fragile history taht went unnoticed by the owner of the voice, but not by the owner of this one



Pitch, loudness and timbre are three characteristics of sonic waves that can be explained by physics magnitudes. Pitch is related with frecuency, high-pitched sounds with high frecuencies and deep voices (like if you are inside a clay pot) belong to the low frecuencies. Loudness, which is usually measured in decibels, corresponds with the intensity and the amplitude of the wave.
Lastly, the today physic concept is timbre, which is what makes you distinguish one sound from another, a violin from a piano, for instance. The timbre depends on the shape of the wave, each sound has a special shape that makes it unique. This peculiar shape never is the perfect armonic one that physicists draw. I didn´t know that, as the text suggests, the timbre is also influenced by the marital status of the focal point of the wave

MIDDLEMARCH (GEORGE ELIOT) AND AN OPTICAL PARABLE ABOUT SELFISHNESS

An eminent philosopher among my friends, who can dignify even your ugly furniture by lifting it into the serene light of science, has shown me this pregnant little fact. Your pier-glass or extensive surface of polished steel made to be rubbed by a housemaid, will be minutely and multitudinously scratched in all directions; but place now against it a lighted candle as a centre of illumination, and lo! the scratches will seem to arrange themselves in a fine series of concentric circles round that little sun. It is demonstrable that the scratches are going everywhere impartially and it is only your candle which produces the flattering illusion of a concentric arrangement, its light falling with an exclusive optical selection. These things are a parable. The scratches are events, and the candle is the egoism of any person 



I would like to add somethiung but the last two sentences make the fuction that usually makes my comment. The experiment can be done at home even if you haven´t got a housemaid. I recommend this amazing novel
