Yet more random sevens…

Western Music

Music Scale from middle C

Music Scale from Middle C

The western musical scale has seven notes, the eighth note being the next level of the first note, hence an octave. The C-scale, one with no half step notes is a basic scale: C,D,E,F,G,A,B,C.  Irving Belin, the author of “God Bless America” and many other tunes,  used only the basic C scale, played only with the white keys.


Newton named seven colors split from white light through a prism


A prism splits light into the rainbow spectrum ranging from red on the long side to violet on the short side: red, orange, yellow, green, blue, indigo, violet. Isaac Newton showed that the coloured light does not change its properties by separating out a coloured beam and shining it on various objects. Newton noted that regardless of whether it was reflected or scattered or transmitted, it stayed the same colour. Thus, he observed that colour is the result of objects interacting with already-coloured light rather than objects generating the colour themselves. This is known as Newton’s theory of colour.

Cervical vertebrae

Cervical vertebrae


Almost all mammals have 7 cervical vertebrae, neck bones between the skull (occiput) and the shoulders (thoractic vertebrae). A primare difference of mammals is that there are no ribs attached to servical vertebrae–we have necks. The first vertebra is called the atlas (it holds up the world of the skull) and the second is called the axis, since that is how the atlas pivots.


colorful periodic table

Periodic Table has seven periods, or horizontal rows of elements. from Wikipedia.

Seven is the number of rows (periods) of elements in the periodic table. The definition of horizontal is a bit different from mine, but I never really got the concept of the periodic table and how it applies, only that it sorts out elements by their properties based on their atomic number. I am so not a scientist.

USA Rugby Sevens

USA Rugby Sevens

Rugby sevens, also known as seven-a-side or VIIs, is a variant of rugby union in which teams are made up of seven players, instead of the usual 15, with shorter matches. Rugby sevens is administered by the International Rugby Board (IRB), the body responsible for rugby union worldwide. The game originated in Melrose, Scotland, where the Melrose Sevens tournament is still played annually. The game is popular at all levels, with amateur and club tournaments generally held in the summer months. Sevens is one of the most well distributed forms of rugby, and is popular in parts of Africa, Asia, Europe, and the Americas, and especially in the South Pacific. The IRB Sevens World Series, an annual competition for national teams in rugby union sevens. The Rugby World Cup Sevens, the World Cup for the union version of Sevens

A converted try is worth 7 points. This number is also significant because the standard bonus points system used in most competitions awards 1 bonus point to a team that loses by 7 points or less.

Mayan Blue Hand Glyph

The glyph for the last day of the last cycle: December 21, 2012,

End of the World

The 7th glyph of the Maya Calendar is Blue Hand, which  represents the days in creation and is associated with creative perfection. This is the glyph of the last day of their calendar that ends on December 21, 2012. Clearly this was not the end of the world as we know it, and the Mayans may have missed the boat with the idea of perfection. Still, there’s hope. Maybe we have another 50,000 year cycle to get it right.

  3. Hmm. I’m not sure what I think, actually! These kinds of things are interesting, but I’m not sure if there’s really any significance. Very cool post, though!
