The ore deposits of the Mesozoic age in South China can be divided into three groups, each with different metal associations and spatial distributions and
The National Science Foundation also got a $100 million dollar budget increase and was told to start cranking out as many new engineers as it could possibly make. Right Now. Sputnik is the reason that schoolchildren in the US have homework. Video clip of Vanguard TV3 utter failure on live...

Satellite communication is a promising transmission technique to implement 5G and beyond networks. Attenuation due to rain begins at a frequency of 10 GHz in temperate regions. However, some research indicates that such attenuation effects start from 5–
These weight reductions would allow the engineers to expand Starship and/or make more built-in structure and/or carry more startup supplies. We will assume the current length of 165 feet with a 30 foot diameter. Three units placed nose-to-tail make 495 feet. But internally there would be ...
The spaceship Nostromo, towing a combined bulk ore carrier and refinery through deep space back to Earth, is brought out of hyperspace and rerouted towards a remote and unexplored planetoid, source of a mysterious generated signal presumed to be a distress beacon. Captain Dallas (Tom Skerrit) ...

When telescopes began to spy on Mars, scientists believed they might be looking at artifiically created canals fashioned by engineers. The illussion of water ways were first observed by the Italian astronomer Giovanni Schiaparelli during the opposition of 1877, and confirmed by later observers. Schi...
