Many of us are familiar with motion in a straight line: you speed up and move faster, you travel forward and end up someplace new. But there is another type of motion: angular motion, or the motion in a circular path. These are the kinematics of a merry-go-round, a spinning top, or the orbit and rotation of the Earth. More »

It’s that time of year again! Time to apply for the *Mathematica* Summer Camp 2013! The camp is being held at Bentley University in Waltham, Massachusetts, July 7–19. Students will have the opportunity to learn *Mathematica*’s computing language, work with Wolfram mentors, and interact with other students with similar interests. By the end of camp, each student will have created his or her very own *Mathematica* program! More »

I’m not a doctor, but for the purpose of this blog post, please imagine that I am wearing a lab coat and a stethoscope—maybe even two stethoscopes, just to be extra professional. Wolfram|Alpha now has an understanding of sig codes, which are the marks on your drug prescriptions that tell the pharmacist what it is you’re getting, what it does, and when precisely it should be taken. Patients aren’t often exposed to sig codes these days, but pharmacy techs learn them, since they receive these abbreviated instructions from the doctor. More »

Throughout the history of physics, scientists have postulated laws and theories about the nature of the world around them. Some were proven false, while others have grown to be the basis of entire fields of study. One such field is classical mechanics, which describes the area of physics most familiar to us, that of the motion of macroscopic objects, from baseballs to planets and traveling along hills to falling from space. As one of the oldest subjects in science, the work here serves as a basis for less familiar areas such as relativity and quantum mechanics. More »
