This is hands down the best way to learn about physics aka statics. Moment is perpendicular distance times force, like a torque of a wrench. This is why ladies with large hooters have lower back problems, there is a large moment/force on their back. Let MIT explain it:
The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis. This is different from the tendency for a body … Read the rest
It’s too bad that it gets harder and harder to build awesome stuff in the USA due to excessive regulations. It took a little over a year to build the Empire State Building in 1930. Now it takes several years to build a tower. Case in point, the new World Trade Center. Read this story:
It took 410 days to build the Empire State Building; four years to erect the Golden Gate Bridge. The Pentagon took two years; … Read the rest

Fujitsu Laboratories has developed a next generation user interface which can accurately detect the users finger and what it is touching, creating an interactive touchscreen-like system, using objects in the real word.
“We think paper and many other objects could be manipulated by touching them, as with a touchscreen. This system doesn’t use any special hardware; it consists of
I’m a nerd and proud of it. As a kid growing up in the ’80s, though, there were few things more terrifying than the prospect of being deemed a nerd for my love of comic books, computers, role-playing games, and myriad other “nerdy” pursuits.
Thinking back on it now, it seems crazy that things considered so mainstream and even cool nowadays could get anyone subjected to near constant ridicule at the hands of their peers, but, oh boy, did they … Read the rest
Ive always been fascinated by lasers they are just such neat devices, the only problem is after a while you get a little bored just shining them at things. I always wanted the 007 laser that will just slice through anything, while this instructable wont give you that but it will let you easily slice through the black trashbag or electrical tape that Dr. No has tied you up with. All you need to be able to do it is … Read the rest
Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, … Read the rest
