蜗居

一 |     2100多年前，古希腊天文学家喜帕恰斯（Hipparchus）绘制了恒星图--在很长一段时间里，这被认为是人类最早的为恒星体指定数字坐标的尝试。但是，尽管它名声在外，这篇论文却只能通过另一位古代天文学家Claudius Ptolemy的著作来了解，他在大约400年后编制了自己的天体清单。

二 | 而现在，研究人员认为他们已经发现了隐藏在一本中世纪希腊手稿中的喜帕恰斯的失落的历史文件的碎片。本周发表在《天文学史》杂志上的一份关于这一发现的研究报告指出：“这一新证据是迄今为止最权威的证据，使重建喜帕恰斯的星图取得了重大进展。

(Xinhua/Liang Xu)The 32nd Asia-Pacific Economic Cooperation (APEC) Small and Medium Enterprises (SME) Ministerial Meeting will be held on Sept. 4 in Guangzhou, south China's Guangdong Province, the Ministry of Industry and Information Technology (MIIT) said on Monday.
The meeting, themed "innovation-driven development for win-win cooperation," will bring together SME officials from APEC economies, representatives of the APEC Secretariat, and other guests.
The meeting will focus on technological innovation, digital empowerment and inclusive development, with a joint ministerial statement and other outcome documents expected, according to Liang Zhifeng, director of the SME bureau under the MIIT.
As the host, China hopes that through in-depth exchanges, all economies will reach forward-looking and practical consensus, promote mutual learning of policies and the translation of outcomes, and jointly enhance the innovation capacity, digitalization level and sustainable development capabilities of SMEs in the Asia-Pacific region, said Vice Minister of Industry and Information Technology Ke Jixin.
Wang Sheng, vice governor of Guangdong, said that all preparations for the meeting are essentially complete, and all APEC economies had confirmed their participation. More than 2,100 companies from home and abroad have registered for the accompanying exhibitions, with over 3,900 booths planned.
China will host the 33rd APEC Economic Leaders' Meeting in Shenzhen in south China in November this year, which will mark the country's third hosting of the event following Shanghai in 2001 and Beijing in 2014.
This year marks the APEC "China Year," with the theme of "Building an Asia-Pacific Community to Prosper Together." Approximately 300 APEC-related meetings and events will take place in multiple Chinese cities throughout the year.
。这一发现可以为天文学的历史带来新的启示。”被称为“三角学之父”的喜帕恰斯，通常被认为是古希腊最伟大的天文学家。

三 | 他的部分星图似乎出现在“Codex CliMaci Rescriptus”中，这是一本叙利亚语文本的书，其中的羊皮纸页被擦掉，可以重新书写，但仍有其早期形式的可见痕迹。这本特殊的重写本存放在埃及西奈半岛的希腊东正教圣凯瑟琳修道院里。来自早期手稿电子图书馆和位于罗切斯特理工学院的拉撒路项目的团队利用不同波长的光揭示了被删除的文字和数字，这种技术被称为多光谱成像。索邦大学和剑桥大学的研究人员随后能够破译四个星座的描述。

四 | 这似乎不仅揭开了喜帕恰斯制图的面纱，而且研究小组还说新发现的数字证据与真实的恒星坐标高度一致。这将使喜帕恰斯的目录比Ptolemy更晚的版本更加准确，尽管研究人员承认他们使用的是一个小样本，而且在喜帕恰斯的星图中没有保存下来的部分可能存在重大错误。

五 | 随着先进的数字技术不断恢复因文件损坏和变质或故意删除而丢失的重要文化遗产，科学家们说Codex Climaci Rescriptus可能会揭示出更多喜帕恰斯的恒星观测。
