It is that FIRST Robotics competition time of the year. Basically, in FIRST, high school students work in teams to build robots that compete in specific tasks. Apparently, this year a task involves ...

THE new Einstein 1 theory is mathematically attractive; but its role in science can only be established through the conclusions that can be drawn from it. Einstein himself hopes that his new theory ...

The equation of motion of a discrete linear system has the form of a second-order ordinary differential equation with three real and square coefficient matrices. It is shown that, for almost all ...

Speed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

The equations of motion of a satellite are given in a general form, account being taken of the precession and nutation of the earth. The main part of the paper deals with the motion arising from the ...
