The global climate is one of the most complex physics problems known to man. The number of variables involved is immense and our ability to measure many of these variables is limited.
Because of the complexity of the climate it is likely that no one will ever be able to predict the global...
It's a good place to vent your frustrations over certain professors and a good place to sing the praises of a professor you really enjoyed. However, this also means that one of students' primary motivations is to make this professor sound either really good or really bad.
It's a good place to...
If you choose a career as a physicist it will pay off to have a working knowledge of computer programming. If you're a theoretical physicist you'll almost certainly be doing some modeling. And if you're an experimental physicist you'll need programming skills for data analysis.
I think that when most people wonder about a fourth dimension, they're thinking of a fourth spatial dimension. Time is of course a temporal dimension so naturally time as the fourth dimension comes as an unexpected answer.
But what, really is the significance of this? No one is really...
Lower case delta is reserved for small but measurable ("finite") changes in some quantity. The d symbol is used in it's place when the change in that quantity is so small that it approaches zero ("infinitesimal").
When integrating and differentiating you should just use a d.
In fact the whole...
This is a statics problem. You want to analyze the point where nothing is moving (everything is "static") but if you were to increase the incline any further the block would either tip or slide.
Anytime you have to solve a statics problem you should immediately think of two things:
1) Sum of...
In this equation:
Q = electric charge passing a certain point in a given amount of time(measured in Coulombs)
I = electric current passing that point (measured in Amps)
As ZapperZ said:
1 Amp = 1 Coulomb / 1 second
So if 2 Coulombs of charge passes a certain point in 1 second there...
One way to approach the problem is to solve the first equation to find all possible values for (z-a). Since (z-a) is raised to the third power in this equation, we expect to find three possible values. This will give you three equations all of the form z-a=#.
I'm not completely sure if I...
Try the set of triangles drawn in the attachment. Draw and label horizontal and vertical lines for each distance you know. And try and work out all of the other distances and angles.
Notice that if you grabbed the point of the triangle at the eye and swung it around to the left you would...
Baggio,
A pi phase shift is introduced into an electromagnetic wave anytime it is traveling through a medium of one index of refraction and reflects off of a surface with a higher index of refraction.
Beamsplitters are made of thin pieces of glass with a coating on each surface that has an...
