Top Laws of Physics?

Wednesday June 10, 2009
Over at the Scienceray blog, they've posted The Top Five Laws of Physics That Have So Impacted Humanity: I'm not necessarily agreeing with this list of the most influential laws of physics ... but I also can't really argue with the idea that they are profoundly significant to our modern science and technology. And, frankly, I can't come up with a much better list (if I'm limited to only 5). The only real beef I have is to point out that Maxwell's Equations include among them Faraday's law of induction, but this isn't a major point: even without Maxwell's work in (mostly) completing electromagnetic theory, Faraday's realization of induction would have been influential on its own.

What do you think of their list? Are these the physical laws that have had the greatest impact on humanity? Leave a comment with what physics concept you think has been most influential.

I love a day when I learn something new.

My choice for a law that was not mentioned was The Three Laws Of Thermodynamics.

Saw the link below and clicked through to it. Discovered that there is not 3, but Four Laws of Thermodynamics!

i like the email concept for information concerning physics. what i don’t understand is when i link onto the page there is nothing pertaining to the original topic. how many times do i link off to get to the heart of the story. why not go straight to the topic instead of …….

Not a Law but the fact of the expansion, and acceleration, of the Universe!

To john peck – I’m not 100% sure what you’re referring to, but it seems like you’re asking why I linked to another story. In this particular case, it’s because I’m talking about another story that’s been adequately written by someone else – so rather than reinventing the wheel, I link to their version of the story and provide my own lead-in and commentary. I also provide links to other articles that I’ve written which elaborate on details of the article … details which the original article may take for granted to some degree.
