One of the first things successful people realize is the old adage, “If it is to be, it is up to me.” That is, for you, the fact that your success and your course is up to you. This doesn’t mean that you do it all alone. It simply means that you take responsibility for your life and your career.

Too many people today look at opportunity and figure it is up to someone else to make sure they get it. They look at financial security and hope that the government will make sure they live safely in retirement or in case of disability. They wait and wait, figuring that it is up to someone else. And then the wait is over, and it is too late to do anything. Their life is over and they are filled with regret.

This isn’t true for you however. You…

Is Quantum Reality Analog after All?: Scientific American, 26 November 2012

Last time when we talked about CCDs, we were concerned with how to take an optical signal, like an image, and convert it to an electronic signal. Then it can be processed, moved, and stored using electronics. But there is an obvious question this idea raises: why is the conversion to electronic signal needed? Why can’t we process the optical signal directly? Is there a way to manipulate a stream of photons that’s analogous to the way that electronic circuits manipulate streams of electrons?

The answer is yes, and the field dealing with optical signal processing is called photonics. In the same way that we can generate electronic signals and manipulate them, signals made up of light can be generated, shuffled around, and detected. While the underlying physical mechanisms are different from those in electronics, much of the same processing can take place! There are a lot of…
