Oskar Klein published the paper describing what later came to be called the Klein paradox in 1929, [1] just as physicists were grappling with two problems: how to combine the theories of relativity and quantum mechanics and how to understand the coupling of matter and light known as electrodynamics. The paradox raised questions about how ...
IRAM is the founder of the Student Internet Radio (existing since 2003) and an organizer of 16 international conferences taking place in Macedonia, UK, the Netherlands and Switzerland (Contemporary trends in musicology and ethnomusicology, Reflections on Macedonian Music, Cultural Policy and Music Education etc.).
The 9.2-inch Mk XI gun introduced in 1908 increased the bore length to 50 calibres in an attempt to increase the velocity still further, but proved unsuccessful in service and was phased out by 1920. The Mk X was hence the final Mark of 9.2-inch guns in widespread British Commonwealth service. The BL 9.2 also affected the development of radar.
[1] [2] These sights work on the simple optical principle that anything at the focus of a lens or curved mirror (such as an illuminated reticle) will appear to be sitting in front of the viewer at infinity. Reflector sights employ some form of "reflector" to allow the viewer to see the infinity image and the field of view at the same time ...
The Mk.10 seat is a development of the Mk.9. Like the Mk.9 it features only one firing handle (the face blind handle being deleted), use of the explosive gas system was extended to operate the drogue gun and harness release system. Arm restraint lines and command ejection capability were new additions. For ease of maintenance the Mk.10 was ...
The centimetric AI. Mk. VIII shown here on a Bristol Beaufighter set the pattern for AI radars well into the 1970s.. Aircraft interception radar, or AI radar for short, [1] is a British term for radar systems used to equip aircraft with the means to find and track other flying aircraft. [2]

This operated at 9.1 cm wavelength (3 GHz), much shorter than the 1.5 m wavelength of the earlier AI Mk. IV. Shorter wavelengths allowed it to use smaller and much more directional antennas. Mk. IV was blinded by the reflections off the ground from its wide broadcast pattern, which made it impossible to see targets flying at low altitudes. Mk.
