从玩器到科学——欧洲光学玩具在清朝的流传与影响

17、18世纪,一批欧洲光学玩具通过耶稣会士等途径流传到大清国,不仅被带入宫廷,而且在民间也得到广泛传播。它们同眼镜、望远镜一起在清朝的社会文化中留下了明显的印记,并促进了中国早期光学工业的诞生。更有趣的是,这些玩具最终还变成了科学研究对象,导致了一种独特的中国式光学系统的建立。     

Construction of largest aperture radio telescope starts in southwest China

While observing the world around us via an optical telescope withinformation carried by visible light, which constitutes only a small portion of the electromagnetic spectrum, astronomers use the remainder of the spectrum to reveal extensive data about celestial objects. For instance, they use telescopes operating in the radio spectrum to explore the universe.

通神的独眼 论伊德为伽利略的望远镜所作的辩护

伊德面对胡塞尔对伽利略的批判而为伽利略辩护,认为望远镜具有透明性。这错失了真正的问题,即伽利略试图将经由望远镜的所见确立为唯一的实在。基督教对质料之抵抗作用的废除、存在论二分向主客二分的转换、伽利略等人对数学的强烈信心,使得数学在亚里士多德主义的自然哲学跌落的背景下上升为唯一不受欺骗的感官。望远镜经由数学的权威而获得权威,成为"独眼"。世界因此失去纵深感,生活世界的意义沉淀在图像之中。伊德正是由于忽视了望远镜背后的这些意涵,才误以为对望远镜的运用能够扭转数学化的不良影响。     

Purple Mountain Observatory

The Very Large Array (VLA) radio telescope which is presently under construction in central New Mexico is considered the highest priority new astronomical facility in the U.S.A. during the next decade. The instrument will consist of 27 separate parabolic antennas each of which will be movable along the arms of a Y-configuration. The technique of earth-rotation aperture synthesis will allow an aperture of 25 miles dia. to be synthesized. When the VLA is completed in 1981 it will be better than any other radio telescope, by one or two orders of magnitude, in terms of resolution, sensitivity and speed.

Probing primordial gravitational waves: Ali CMB Polarization Telescope

In this paper, we will give a general introduction to the Ali CMB Polarization Telescope (AliCPT) project, which is a Sino–US joint project led by the Institute of High Energy Physics and involves many different institutes in China. It is the first ground-based Cosmic Microwave Background (CMB) polarization experiment in China and an integral part of China''s Gravitational-wave Program. The main scientific goal of the AliCPT project is to probe the primordial gravitational waves (PGWs) originating from the very early Universe. The AliCPT project includes two stages. The first stage, referred to as AliCPT-1, is to build a telescope in the Ali region of Tibet at an altitude of 5250 meters. Once completed, it will be the highest ground-based CMB observatory in the world and will open a new window for probing PGWs in the northern hemisphere. The AliCPT-1 telescope is designed to have about 7000 transition-edge sensor detectors at 95 GHz and 150 GHz. The second stage is to have a more sensitive telescope (AliCPT-2) with more than 20 000 detectors. Our simulations show that AliCPT will improve the current constraint on the tensor-to-scalar ratio r by one order of magnitude with three years'' observation. Besides the PGWs, AliCPT will also enable a precise measurement of the CMB rotation angle and provide a precise test of the CPT symmetry. We show that three years'' observation will improve the current limit by two orders of magnitude.
