haha some truth in there :wink:

I like science in part because I thought religion is irrelevant to science. Science is at its basis simply exploration married to intelligent analysis. When I read about quantum physics interpretations I hear about proponents (followers) of these different interpretations. What is religion...

Hi, Interesting article here about how : "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it." -...

For a person who like to go forward in the Computer Field, what is the best to choose in higher education? Computer Science or Engineering(Software/Hardware/Network .etc)? {And also what are the differences regarding the economical benefits related to Computer Science and Computer Engineering?}

I wasn't sure where to post this, but I figured this would be a topic under General Physics. I am aware that the next generation of observations, ranging from cosmological observations to post-LHC particle physics experiments, will produce overwhelmingly large and complex datasets, far larger...

I am doing some experimentation, for a science fair. And I want to make sure I the laser pointer I use is Class I (conceivably, I may change that, but any class of laser can be used to replicate results similar to the double slit experiment correct?). Can anyone direct me as to where I may be...
