It has to be said that in recent years, Apple has really encountered a difficult opponent on the road of "squeezing toothpaste". The iPhone 15 Pro, which officially launched on the 22nd of last month, has been upgraded to a regular processor, replaced with a titanium metal frame, TypeC interface, and Action button, which has brought several painless upgrades...

Source: [Love Jinan News Client]On the 8th, the reporter learned from the University of Science and Technology of China that Associate Professors Cai Zhenyi and Wang Junxian of the Astronomy Department of the university, through studying the extreme ultraviolet radiation spectrum of the accretion of supermassive black holes at the center of quasars, found that it is not related to the intrinsic brightness of quasars, overturning traditional understanding in this field. Further research by researchers has found that the average extreme ultraviolet energy spectrum of quasars is much softer than expected by classical accretion disk theory, posing a serious challenge to classical accretion disk radiation models and strongly supporting accretion models with universal disk winds...
