Black student suspended over his hairstyle to be sent to an alternative education program_我的网站

A |     After serving more than a month of in-school suspension over his dreadlocks, a Black student in Texas was told he will be removed from his high school and sent to a disciplinary alternative education program on Thursday.Darryl George, 18, is a junior at Barbers Hill High School in Mont Belvieu and has been suspended since Aug. 31. He will be sent to EPIC, an alternative school program, from Oct. 12 through Nov. 29 for “failure to comply” with multiple campus and classroom regulations, the principal said in a Wednesday letter provided to The Associated Press by the family.Principal Lance Murphy wrote that George has repeatedly violated the district's “previously communicated standards of student conduct." The letter also says that George will be allowed to return to regular classroom instruction on Nov. 30 but will not be allowed to return to his high school's campus until then unless he's there to discuss his conduct with school administrators.Barbers Hill Independent School District prohibits male students from having hair extending below the eyebrows, ear lobes or top of a T-shirt collar, according to the student handbook. Additionally, hair on all students must be clean, well-groomed, geometrical and not an unnatural color or variation. The school does not require uniforms.George's mother, Darresha George, and the family's attorney deny the teenager's hairstyle violates the dress code. The family last month filed a formal complaint with the Texas Education Agency and a federal civil rights lawsuit against the state’s governor and attorney general, alleging they failed to enforce a new law outlawing discrimination based on hairstyles. The family alleges George's suspension and subsequent discipline violate the state’s CROWN Act, which took effect Sept. 1. The law, an acronym for “Create a Respectful and Open World for Natural Hair,” is intended to prohibit race-based hair discrimination and bars employers and schools from penalizing people because of hair texture or protective hairstyles including Afros, braids, dreadlocks, twists or Bantu knots. A federal version passed in the U.S. House last year, but was not successful in the Senate.The school district also filed a lawsuit in state district court asking a judge to clarify whether its dress code restrictions limiting student hair length for boys violates the CROWN Act. The lawsuit was filed in Chambers County, east of Houston.George’s school previously clashed with two other Black male students over the dress code. Barbers Hill officials told cousins De’Andre Arnold and Kaden Bradford they had to cut their dreadlocks in 2020. Their families sued the district in May 2020, and a federal judge later ruled the district’s hair policy was discriminatory. Their pending case helped spur Texas lawmakers to approve the state’s CROWN Act. Both students withdrew from the school, with Bradford returning after the judge’s ruling. ___AP journalist Juan Lozano contributed to this report from Houston.___The Associated Press education team receives support from the Carnegie Corporation of New York.

B | 每平方米太阳能电池板在太空中的能源潜力是地球上的八倍。

C | 问题一直是如何做到这一点--以及事实上，它将花费多少钱。

D | 在太空中发射、组装和维护设备的成本是天文数字。

E | 一个有价值的太空太阳能装置的规模是令人难以置信的，而前所未有的问题在旅程的每一步都带来巨大的障碍。加州理工学院的一个团队并不气馁，而且确实被这一挑战所激励，他们已经在太空太阳能项目上工作了近十年。早在2013年，Irvine公司董事长(Donald Bren就为该项目提供了超过1亿美元的惊人捐赠--这笔捐赠最近才被披露，2015年诺斯罗普-格鲁曼公司又为该项目提供了1750万美元的资金。该项目基本上是在三个方面进行的。一个小组一直在研究重量极轻的高效光伏电池，其功率重量比甚至比目前在国际空间站和现代卫星上使用的太阳能电池板高出50-100倍。第二个团队专注于开发超轻、微型、低成本的设备，将来自太阳能电池板的直流电转换为射频功率，然后将其传送到地球上，使用相位操纵将光束电子化地引导到地面上的接收器阵列。这两个团队已经将他们的进展结合到一个“瓦片”的功能原型中--大约10平方厘米，结合了太阳能捕获、转换为射频和无线传输。这些高度集成、非常灵活的“瓦片”，每块的重量不到十分之一盎司（不到2.8克），它们被设计成可折叠的配置，基本上没有浪费的空间，被放入运载火箭并送入轨道，在那里它们会自己展开。因此，整个空间太阳能阵列被设想为一个超模块化的组件。

F | 这些“瓦片”被设计成2米宽的条状，长度可达60米。这些条状物被整合成大约60×60米的模块。因此，第三个小组一直在研究如何建立一个全尺寸的阵列，将数以千计的“瓦片”组合成模块，并将数以千计的模块组合成一个巨大的太阳能收集和传输阵列，面积约为9平方公里。这个小组得到的挑战是为这些模块创造超轻、超薄的空间结构，这些结构可以非常紧密地折叠起来，然后自主地展开成巨大的模块，并在阵列像飞毯一样在太空中呼啸时保持其形状和位置。这个团队已经做了一些惊人的工作；受日本折纸和卷纸的启发，他们已经设计并制作了卷曲、折叠、自组装的结构原型--包括可卷曲的接头--每平方米仅重150克。
