Introduction Have you ever seen video footage of an avalanche or landslide rolling down a hill? Why is it that at one moment everything seems fine then suddenly the mountain begins to slump? This ...

Traditionally, slope-angle readings have been obtained by measurement between identifiable breaks of slope, but this method includes a large subjective element and imposes restrictions on subsequent ...

Running uphill on steep inclines is never easy, but researchers at the University of Colorado Boulder have discovered a range of slope angles that would allow an athlete to ascend a mountain most ...

Now for the physics. I think there are three reasons why a slope would be too steep. For all of these cases, I am going to assume that it is a prolonged slope. This means that you can't just build up ...

This is the famous Bent Pyramid. The lower part of the pyramid has an angle of 54° and the upper part is at 43°. Why is it bent? Really, who knows. The two likely reasons are: Time or money (well ...
