In Harmonices Mundi (1619) Kepler attempted to explain the harmony of the world and contained what is known today as his third law. The work was founded on geometry, from which Kepler derived first a theory of musical harmony and then a cosmology of the heavens and the earth. Kepler attempted to find common rules between music and movement in the solar system. His music of the spheres is based on the relative maximum and minimum angular velocities of the planet measured from the sun. Using his theories, Kepler allotted to the planets musical intervals and musical motion.
“The Earth sings Mi, Fa, Mi: you may infer even from the syllables that in this our home misery and famine hold sway" -Kepler.
Johannes Kepler (1571-1630) was a German mathematician, astronomer and astrologer. A key figure in the 17th century scientific revolution, he is best known for his laws of planetary motion based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy. These works also provided one of the foundations for Isaac Newton’s theory of universal gravitation.
Prints of Harmonices Mundi are available here. Does anyone know what “Hiclocum haber eriam” means?
Answer to the question: It’s hic locum habet etiam (This [celestial body] always holds this place). It’s the moon.
One of the things I missed most about being home is my espresso machine.
if trees could talk i’d probably get emotionally attached to them
until then, let’s continue cutting them down.
I learned to enjoy playing drum set. This is a big deal for me. I’ve always disliked drum set for some reason that I couldn’t quite pinpoint. I think it was just because I hadn’t played it that much, aside from in private lessons. This was the first time I had ever performed on drum set, and was depended upon whilst playing. I played quite a bit this summer, and I realized that maybe I just needed to spend some time on the drum set getting to know it in a different context than a private lesson. It also didn’t hurt that all of the kids looked up to me and thought I was the best drummer since sliced bread. Someone even wrote that I was the “batoven of drummers”. Too adorable.
My parents were able to come up and watch the evening concert. John William’s Escapades from Catch Me If You Can, Smetana’s Moldau, and Tchaikovsky’s Symphony No. 1. Each piece got a standing ovation, and at the end of the concert when Hans Richter, our guest conductor, recognized the percussion section, we got the loudest applause. They really do love us here.
I must say, I really nailed the timpani part in the Moldau. I’ve never been that nervous
excited for any kind of large ensemble performance before.
They’re sending the recordings of last night’s concert to NPR! I’ll have to keep my eyes peeled.
I couldn’t get a good internet connection last night, so I had to wait until this morning.
