12 Tone Equal Temperament
On a standard piano keyboard, one octave is divided into 7 whole tones: A, B, C, D, E, F and G. In between these tones are 5 further notes which can be called either sharps or flats: A# (Bb), C# (Db), D# (Eb), F# (Gb), G# (Ab). (whether it's a sharp of a flat doesn't really matter, the note has the same frequency, just a different name). This gives us a grand total of 12 notes in one octave.
If you were to measure the frequency of a note, then measure the frequency of a note exactly one octa...Folksonomies: mathematics music

The Mind on Music
For some reason that no one really understands, there is a psychological effect upon human listeners in regards to the musical scale. The tonic pitch, or tonal center is not only the mathematical center of the scale, but is the psychological center as well. Human perception of the tonic pitch in relation to the other notes of the scale gives each note of the scale, including the tonic pitch, a distinct "personality" or identity. If we were to label each note of the major scale with a number, ...09 NOV 2015 by ideonexus
Exercises for Emotional Maturity in Children
Let's focus on the skill of expanding sensitivity. Increased attention to music, nature, and animals can increase sensitivity. Once you identify these outlets, set up a series of exercises that use these focal points to draw out sensitivity. For example:
Listening: Listen to a piece of beautiful music for 10 minutes. Close your eyes and let the notes guide your mind.
Focusing: Choose an animal (even an ant) and follow it for 10 minutes; watch it with full attention.
Relaxing: Sit quietly for...

Transcription Fluency
When you write something down, either while taking notes or while trying to write your own original thoughts, you’re dealing with what literacy scholars call “transcription fluency”: How quickly and fluidly you can get down — “transcribe” — the stuff that’s in your head. One of the reasons we formally teach handwriting to young children is that you don’t want a bottleneck between the ideas they’re forming and the writing. If you struggle with the act of forming let... 1 notes

Questioning the Milgram Experiment
It appeared that sixty-five percent of people would torture someone to death, if pressured to do so. The results made their way into both psychology and cocktail party conversation. But were they correct? At least one woman doesn't think so. Gina Perry, for her book, Behind the Shock Machine, traced as many participants in the Milgram experiment as she could, and re-examined the notes of the experiment. Milgram claimed that seventy-five percent of the participants believed in the reality of t...Folksonomies: psychology ethics

notesThese questions raise an even greater objection to the validity of the experiment. If the results cannot be reproduced, because the experiment was unethical, then we shouldn't cite it a evidence of anything every. Science demands reproducible results, and without replication we do not have evidence.

The Magical Number Seven
What about the magical number seven? What about the seven wonders of the world, the seven seas, the seven deadly sins, the seven daughters of Atlas in the Pleiades, the seven ages of man, the seven levels of hell, the seven primary colors, the seven notes of the musical scale, and the seven days of the week? What about the seven-point rating scale, the seven categories for absolute judgment, the seven objects in the span of attention, and the seven digits in the span of immediate memory? For ... 1 notes

Experiments Were Sacred to Darwin
Although [Charles Darwin] would patiently go on repeating experiments where there was any good to be gained, he could not endure having to repeat an experiment which ought, if complete care had been taken, to have told its story at first—and this gave him a continual anxiety that the experiment should not be wasted ; he felt the experiment to be sacred, however slight a one it was. He wished to learn as much as possible from an experiment, so that he did not confine himself to observing the... 1 notes

Discovery By Wislawa Szymborska
I believe in the great discovery.
I believe in the man who will make the discovery.
I believe in the fear of the man who will make the discovery.
I believe in his face going white,
His queasiness, his upper lip drenched in cold sweat.
I believe in the burning of his notes,
burning them into ashes,
burning them to the last scrap.
I believe in the scattering of numbers,
scattering them without regret.
I believe in the man's haste,
in the precision of his movements,
in his free will.
...A chilling and insightful poem about faith and how it blinds people to evidence.

Is Beethoven's <em>Fifth Symphony</em> a meme, or only th...
Whether by coincidence or by memetic transmission, Beethoven is the favourite example for illustrating this problem. Brodie (1996) uses Beethoven's Fifth Symphony, Dawkins (1976) uses the Ninth and Dennett (1995) uses both the Fifth and the Seventh. Dennet adds that the first four notes of Beethoven's Fifth are a tremendously successful meme, replicating all by themselves in contexts in which Beethoven's works are quite unknown. So are they the meme, or the whole symphony?
If we cannot answe... 1 notes
