Larger lenses

Despite the popularity of cheap plastic lenses, glass lenses are still essential for many applications. To make a glass lens, a gob of molten glass is dropped onto a catching tool, which compresses it into the desired shape. This glass blank is then polished to the correct magnification. However, the compression method used to manufacture […]

Fast spinning pulsar

Frank Marshall, Will Zhang and Eric Gotthelf from the Goddard Space Flight Center, and John Middleditch of Los Alamos National Laboratory found the star by studying data from NASA’s Rossi X-Ray satellite. They have calculated that the star is spinning over 60 times per second, twice as fast as any previously known pulsar. The pulsar […]

Critical issues at the original nuclear lab

First published November 1997 in Physics World As the sixth director of the Los Alamos National Laboratory, John Browne faces broad challenges at a critical time in the laboratory’s history. After a lifetime of secrecy – the first atomic weapons were built there in 1945 – public concerns are forcing the lab to become more […]

UK focuses on research strengths and opportunities

The analyses were commissioned by Sir John Cadogan, director general of the research councils, who chairs a panel that is reviewing the UK science budget. He is using the SWOT analyses to help him judge the impact of publicly-funded research on the government’s long-term objectives. Cadogan is also consulting professional bodies and learned societies to […]

Organic laser breakthrough

Organic lasers are attractive for optical applications because they are inexpensive to manufacture, can be grown as thin films and have good temperature stability. Results from the Princeton team suggest that they can be made to operate at wavelengths between 460 and 510 nm, making them ideal for use in optical storage devices. The Princeton […]
