because your vestibular system relies on the downward pull of gravity to tell you which way is up (and in which direction you are moving), it does not function in microgravity. So your eyes may tell your brain that you are upside-down, but your brain does not receive any interpretable in...
A Boeing 747-8 passenger airliner, for instance, has a maximum takeoff weight of 487.5 tons (442 metric tons), the force with which the weighty plane is drawn toward the Earth. Weight's opposing force is lift, which holds an airplane in the air. This feat is accomplished through the ...

However, prices have trended downward in recent years, and brought photovoltaics more in line with the cost of wind turbine construction. An effective alternative to the photovoltaic system is known as the concentrated solar plant. This method does away with silicon panels and instead uses a ...
(a force we experience as our weight) and the Earth to us; however, Earth’s massive size makes its movement towards us imperceptible, i.e., even though we pull the Earth a little bit towards us, it goes unnoticed because of the Earth’s much greater mass. The greater the mass of ...
The water that most of us see or experience is only a very small portion of the total. Actually, that statement should be qualified: the oceans, parts of which most people have seen, make up about 5.2% of Earth's total water supply. This may not sound like a large p...
Every TD is a unique structure at a unique site and therefore requires a unique design; “off-the-shelf” designs have no place in modern tailings management facilities. Therefore, engineering experience in tailings disposal must be integrated with the results of theoretical, field, and laboratory...
