acoustic properties
The great chamber of Newgrange resonates effectively at 110 Hz, and the 19m (62-foot) passage behaves like a wind instrument, with sound waves generated within the chamber filling it, their amplitude decreasing towards the entrance.
The 110 Hz frequency is in the baritone range the second lowest level of the male singing voice. It is therefore possible to speculate that chanting male voices could have been used in these supposed tombs for the silent dead. This could have been on ritual occasions, or for oracular purposes, in either case most probably at those times of year marked by the entrance of sunbeams into the chambers, for these sites are astronomically aligned at the 5000-year-old Newgrange, for instance, the beams of the rising midwinter sun shine through a special roof box above the passage entrance, down the long passage and into the central chamber, making the stones there glow like living gold.

(4,940 posts)I had an uncle, now many years deceased, who made a "last pilgrimage" to Ireland before his death. He brought home photos of this and many other "ruins". The pictures are now gone, lost to a flood at my mother's home in 1978 but the memories will never be lost. Ah, he was a storyteller, was my Uncle Sean!
Thank you. Tears of happy!

(13,485 posts)Exactly two octaves lower than concert pitch A440 which is the only standard or absolute pitch that exists in modern western music. In the 12 tone scale that we use, A is the only absolute pitch, all others are relative to it.
I thought that was an interesting coincidence though the pitch itself is arbitrary in general. Natural earth sounds tend toward F#. The Aurora Borealis is about F# as I have heard it many times. It never changes. I wonder if there is some sort of reason for the A110 or if it was coincidental? Not only Baritones sing A110 and it's not even considered a middle their range. It's considered a low Baritone note but it is in the middle of the Bass range. Just sayin'

(36,988 posts)Dr. Ian A. Cook of UCLA and colleagues published findings in 2008 of an experiment in which regional brain activity in a number of healthy volunteers was monitored by EEG through different resonance frequencies.
Findings indicated that at 110 hz the patterns of activity over the prefrontal cortex abruptly shifted, resulting in a relative deactivation of the language center and a temporary switching from left to right-sided dominance related to emotional processing. People regularly exposed to resonant sound in the frequency of 110 or 111 hz would have been "turning on" an area of the brain that bio-behavioral scientists believe relates to mood, empathy and social behavior.

The science of Cymatics illustrates that when sound frequencies move through a particular medium such as water, air or sand, it directly alters the vibration of matter. Below are pictures demonstrating how particles adjust to different frequencies.

(31,849 posts)So much disparate knowledge, known and, connected to other knowledge.
Ichingcarpenter
(36,988 posts)Students dont view knowledge as cumulative and useful across courses and hence dont draw on relevant prior knowledge from other courses
Even though students can demonstrate proficiency gained in other courses in simplified contexts (e.g., articulating a single argument, executing a technique), they have difficulty applying the same knowledge and skills in new courses under different demands (e.g., when integrating ideas from different sources, applying what they have learned in a new context).
This is a common problem in capstone courses, where the goal is to help students integrate and apply knowledge they have learned across multiple courses in the preceding several years. These intellectual tasks are challenging for students because they require students to identify which knowledge is relevant from a vast array of things they have previously learned, simultaneously consider the implications of multiple pieces of information, and then integrate this disparate knowledge as they apply it in the current context.
For example, students asked to design a bridge in a senior civil engineering capstone course need to draw on concepts from courses such as physics, calculus, structural engineering, and materials science and integrate this knowledge as they create a new design.

(31,849 posts)By "disparate knowledge" I meant one DUer shares one piece of knowledge on a subject, followed by another DUer sharing more on that subject, or a piece of information on a related subject, which allows me, one with little knowledge on either subject, a starting place to expand my own knowledge.
Does that make sense?

The Hypogeum of Hal Saflieni in Malta is a UNESCO World Heritage Site which is believed to be the oldest prehistoric underground temple in the world. The subterranean structure is shrouded in mystery, from the discovery of elongated skulls to stories of paranormal phenomena. But the characteristic that has been attracting experts from around the globe is the unique acoustic properties found within the underground chambers of the Hypogeum.
Hal Saflieni Hypogeum is a cultural property of exceptional prehistoric value, dating back approximately 5,000 years and the only known example of a subterranean structure of the Bronze Age. The 'labyrinth', as it is often called, consists of a series of elliptical chambers and alveoli of varying importance across three levels, to which access is gained by different corridors. The principal rooms distinguish themselves by their domed vaulting and by the elaborate structure of false bays inspired by the doorways and windows of contemporary terrestrial constructions. Although not known for certain, it is believed that the hypogeum was originally used as a sanctuary, possibly for an oracle. It is for this reason that a unique chamber carved out of solid limestone and demonstrating incredible acoustic properties has been called the Oracle Chamber.
According to William Arthur Griffiths, who wrote Malta and its Recently Discovered Prehistoric Temples, a word spoken in the Oracle room is magnified a hundredfold and is audible throughout the entire structure. The effect upon the credulous can be imagined when the oracle spoke and the words came thundering forth through the dark and mysterious place with terrifying impressiveness."

(36,988 posts)music in general and its effect on special education students.
for example I found that
ADHD students did better listening to rap or heavy metal on certain tests than classical but performed better under both vs no music.

(69,014 posts)The python (I heard there's an African country where it's illegal to kill them) coils around its eggs to hatch them. It's a Great Mother symbol. Found in caves and dangling from trees, like the one in Eden.
If you see a python dangling from a tree above a cave, my bet is that cave contains a source of potable, accessible water. And knowing that would be a very wise thing.
