Wishing for a high quality music environment, I did some research into audiophile headphones. I learned that there does not exist a “best” pair of headphones. Rather, there are various headphones which are great for their reproduction of various parts of the audio spectrum. For example, the ones that I bought, the Sennheiser HD 598s are known to be good (considering their price) for listening to the higher side of the spectrum; i.e., vocals and other high frequency sounds. I must say that I love my Sennheiser HD 598s. Sennheiser produces a couple of other highly rated headphones, including the HD 650 and HD 800. Here are some other headphones which have good reviews: Beyerdynamic DT 770, AKG K702, Grado SR60, Grado RS1, and the ATH M50. Also, to get the best sound out of the headphones, one should buy an amplifier.

It’s a rare conversation that mentions the importance of women in the history of math and science. I am not too sure why, as there have been many important women in the history of math and science. To prove this, just check out Hypatia, Emmy Noether, and Henrietta Swan Leavitt. Leavitt made the discovery that Cepheid variable stars are the key in finding the distance to galaxies. To be more direct, she found out how to measure the universe. Anyone interested in this story should read George Johnson’s book, Miss Leavitt’s Stars: The Untold Story of the Woman Who Discovered How to Measure the Universe.
I am not sure why, but I bought On the Shoulders of Giants, by Steven Hawking, with the intention of reading the entire 1280 page volume. I was not able to finish any of the works contained in the anthology. Not because of their difficulty, but because I found all of them, except Einstein’s boring. This is probably because I grew up reading so many books that already assumed that the planets orbit the sun in ellipses according to Kepler’s laws. All the works are legendary from a historical perspective, since they basically changed the course of science and history. The book is a neat addition to a library collection.
There are some interesting theories about Egyptians and Cymatics. Check this link for more information. Perhaps the Egyptians knew about the formation of such patterns (as can be seen in this video) and thought them “holy.”
