CP Violation

What does the CP violation mean?


This article talks about “The puzzling decay of the neutral kaon.” I had a very hard time getting the jist of this article, but it sounds like scientists had a general theory called the CPT theorem. Some testing was done which violated this general theory and surprised them. They either had to scrap the original theory or accept some surprising results.  Apparently, until the 1960’s scientists thought particles decayed at the same rate whether time ran forward or backward. There were some tests done at Princeton in which the CP was violated. According their findings, they were faced with a choice; either the CPT theorem was incorrect, or the kaon decays at a different way in a universe where time runs backward.

“The particle decay arrow seems completely unconnected with all the other arrows of time.” Strange!

I would imagine that it is very hard for some scientists to let go of the findings they have come to rely on for the basis of their understanding of the universe. What ideas seemed to fit at the time of their discovery and made so much sense are not working anymore with new discoveries and understandings of today.

I have been an herbalist for the past 15 years studying and teaching classes in herbal medicine making, nutritional benefits of herbs and herbal teamaking. In 2016 I co-taught a series of essential oils for self care classes for Sonoma Valley Hospital staff, and completed a year long certificate program in Health Navigation at Sonoma State. I have a small herbal products company and currently make and sell a savory herbal seasoning locally in Sonoma, work as a natural foods personal home cook, food artisan and soupmaker. I am also participating in a acupuncture tutorial program at Sonoma Valley Acupuncture and Herb Center and am excited to be learning about Chinese medicine.

8/8/18 Bionics: The development of a bionic person and it's use in the military

8/8/18 Supporting Bionics for Humans? My first feeling about this topic is that I would support the option of bionics for humans in need of limbs, in place of old prosthetic limbs that have previously existed. I have not had to worry about this personally for myself or any of my family members, but I imagine that for someone who does, advances in science in this field are really important for having a more functional, happy life. I had a childhood friend who didn’t need a prosthetic limb, but was disabled and needed braces from the waist down as a child to assist with walking. These things were heavy, stiff, ugly and just archaic! It sounds like newer developments are moving toward more sophisticated options that are more accessible for average people. The UK based tech company mentioned in our readings is using 3-D printing technology to create prosthetic limbs which are more affordable. This sounds like a good thing. Especially for a child, being mobile and being able to do t...

7/30/18 I know I am a living system because..... Wow! Crazy how things can become not so black and white when you begin to look into what is considered a living thing. According to NASA, all living things share a carbon based chemistry, depend on water, or leave behind a fossil with carbon or sulfur isotopes that point to a past metabolism. Scientists struggle to define "life." From what I have read so far, it seems like something could be considered living and have certain characteristics of life, while others may be "alive"  and have slightly different characteristics. Crystals are interesting. They can grow and respond to stimuli but lack a nervous system. I believe there are many different forms of life and we can see things as living that are not what we would expect. In a Native American perspective even rocks are infused with spirit, is that a living thing?
