Starlight bent by the Sun's Attraction: The Einstein Theory
This diagram drawn by W. B. Robinson illustrates Professor Einstein's Theory that light is subject to gravitation. The drawing was based on British observers' photographs at the eclipse of the sun on the 28-29th May 1919. Photographs of stars were taken during the total eclipse, which were then compared to other plates of the same region taken when the sun was not in the neighbourhood. Comparing the two plates, the stars on the eclipse plates seemed to be pushed outwards, thus starlight was found to be bent by the sun's attraction. Dr A. C. Crommelin, a British observer working on the project, wrote that 'straight lines in Einstein's space cannot exist; they are parts of gigantic curves.'

Philae Temple - Aswan, Egypt
Philae - originally located near the expansive First Cataract of the Nile River in southern Egypt, and was the site of an Ancient Egyptian temple complex. The temple was relocated to nearby Agilkia Island as part of the UNESCO Nubia Campaign project, protecting this and other complexes before the 1970 completion of the Aswan High Dam. This immense engineering undertaking was part financed by the procceds generated by the worldwide success of the touring Tutankhamun exhibition. Date: 1908

Underwater house equipment under construction, Malta
Young man assembling electronic equipment connected with an underwater, inflatable house under construction on a beach in Malta. The house was anchored to the seabed, some 50 feet deep, in Paradise Bay, off the coast of Malta. It was equipped with lighting, telephone and immersion heaters with which the inhabitants could make hot drinks. It was constructed by teams of engineers and diving enthusiasts from Imperial College of Science and Technology and Enfield College of Technology. It was 9ft long and 6ft wide, constructed from rubberised material on a steel frame, and weighed around 500 lb. The team leader was David Baume who hoped it would be the first of a series of low cost underwater living spaces from which scientists could explore the seas. David and some other team members were able to spend a night 30 feet below the surface. The following day a severe storm caused the house to collapse.
