Well, the crudest way is to use a stomper, which is a plank of wood with a rope attached to both ends. People hold the two pieces of string and put the plank underneath their foot and knock over plants. But ever since the explosion of crop circles in the last few decades, there ar...

The support is close to the goaf side to lay the net, hang the wire rope, spray the slurry, and be supplemented by the air duct cloth to control the air leakage, thus forming the GER. (4) using the GER, the hydraulic supports arranged along the goaf should be rapidly retraced from ...
[W]hen Galileo discovered he could use the tools of mathematics and mechanics to understand the motion of celestial bodies, he felt, in the words of one imminent researcher, that he had learned the language in which God recreated the universe. Today we are learning the language in which God...
Penrose1 and Bekenstein2 have considered the idea of slowly lowering a particle at the end of a rope into a black hole—or rather its ergosphere—and thereby letting the gravitational field do work on the apparatus at the upper end of the rope. In effect we have an excellent form of was...
So it wasn’t really too far afield from recreational math, because the two books are filled with all kinds of mathematical jokes. I was lucky there in that I really didn’t have anything new to say in The Annotated Alice because I just looked over the literature and pulled together ...

He excelled in(擅长)math and science and attended New York University with the intention of becoming a doctor. But he says fashion always interests him. His mother was employed in the garment industry(制衣业)and he would watch her at work. To help support himself during college, Antho...
Kepler worked ten years trying to work out the math,including calculating various epicenters,based on Tycho's careful observations.A degree of arc is divided into 60 minutes each of which is divided into 60 seconds.Therefore there are 360 degrees of arc in a circle,21600 minutes of arc,and...
Nothing with which it can be compared, though the proverbial Six Blind Men of Indostan did their best, likening each part encountered separately to a snake, a spear, a fan, a wall, a tree, and a rope. Taken altogether, these ingredients add up to a most singular animal…. ...
