Why Tubes Sound Good in Audio Systems

Tubes or solid state transistors in audio playback systems? There’s been a decades-long debate over this in the audio world. Solid state measures better. Tubes usually measure worse and yet many people will tell you that tubes sound better. Personally, I prefer to use tubes at the preamp level. Ken Rockwell has written a good article on this subject.

Bee Colonies Growing in Michigan

The number of bee colonies in Michigan are up 50% since 2018. This is significant because for the last 20 years, the number of bee colonies in Michigan were in decline. The pollination that bees provide are necessary in order to grow many types of fruits and other foods for human consumption. “The leading cause in declining populations is believed to be exposure to pesticides, insecticides, parasites, and pathogens, as well as limited sources of nectar and pollen.” (Link)

China Sets Target of Carbon Neutrality by 2060

China, the largest producer of greenhouse gases, gave itself a target to be carbon neutral by 2060. Carbon neutrality is a strategy that aims to balance carbon dioxide emissions with carbon removal, and may be an effective mechanism to improve air quality. This would be especially significant for many Chinese citizens who live with regular, high levels of air pollution. Seven of the ten cities with the most air pollution worldwide are found in China.
