Much lower gravity levels may have some value, for lab & fab more than crew. The figure above[23] suggests that many processes have different minimum and maximum gravity tolerances, with some overlap. Slow-spinning crew-tended AG can offer low enough gravity near the spin axis for some “mi...
However, it is not known what the minimum requirements are, whether they vary for different physiological systems and whether passive zero gravity or the enhancement of the effects of activity conducted in an increased G field are more effective. It is similarly not known what the optimal ...
None of our space stations thus far have had any gravity. One reason for this is that we want a place without gravity so that we can study its effects. Another is that we lack the technology to practically rotate a large structure, like a space station, to produce artificial gravity. In...
In order to accomplish this, ASIMO's engineers had to find a way to work with the inertial forces created when walking. For example, the earth's gravity creates a force, as does the speed at which you walk. Those two forces are called the "total inertial force." There is also the fo...
Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
The natural sources of all the elements. Artificial elements are created atom by atom, and almost everything else is made in supernovas and neutron star collisions. Artificial isotopes can be created by bombarding existing isotopes with “slow” neutrons, some of which stick to...
and never take a lift to go downstairs. If in the open air, find an open place and never get close to cars or waterside. Thirdly, we should help each other when we meet trouble. At last, no matter how strong the earthquake is, if only we have the belief to defeat it and never ...
It is a type of wind erosion where small particles are lifted from the ground by the action of the wind to a different place. Particles are broken down by wind and bounce too different directions. Human beings breathe in these particles, resulting in airborne diseases....
The car itself—based on the readily availableWLToys A979—has all the things the model car doesn’t: proper tires, suspension, and differential. One problem is that the car is heavy—around 1.5 kg—and the placement of some components causes the center of gravity to be very high. This ...
The telescope used in this video was an Explore Scientific ED102. The modest aperture of this apochromatic refractor makes capturing flat frames easier, as there is less area to cover. Larger telescope objectives, such as a Newtonian Reflector, may find an artificial lighting solution more effecti...
