The search for ancient neutron stars

Over the course of its 10 billion year history, our Galaxy is believed to be populated by as many as a billion neutron stars - superdense remnants born after the violent deaths of stars much more massive than our Sun. Studying the older members of this population - the vast majority - is key to understanding the long-term evolution of these objects and their role in the chemical enrichment of our Galaxy. Positively detecting these objects, however, has proved to be extremely challenging, primarily due to their extreme faintness. Candidates exist at present, but number far fewer than originally expected.     

中国古代科学遗产的现代社会功能

中国古代有着发达的科学技术,其上发展起灿烂的中国古代文明。但是,今天发掘、研究中国古代科学遗产,决非只局限于发掘具体的成果。这是因为古代科技成果,在当时虽很先进,但在今日,其原理也只能放在中小学教科书中介绍。今天,我们发掘、研究古代科学遗产更多应着眼于发掘有民族特性的自然观、科学观、方法论以及与科技活动有关的价

Diffusion of astronomy in the ancient world

Astronomical techniques, calendars and devices were developed independently in many places around the world. However, there was much cross-cultural exchange of technology over the centuries. The cultures of Egypt, Greece, India and China influenced each others’ astronomy and each cannot be treated in isolation.     

Reconstructing the ancient Greek trireme warship

Although the trireme played an essential role in the rise of the Greek city states there is still much controversy about its design and construction. There is, therefore, much interest in a current Anglo-Hellenic project to reconstruct a trireme, on the basis of the best available evidence, and conduct trials at sea. When complete, the vessel will be a principal exhibit at the new Hellenic Maritime Museum in Athens.
