tks. for your reply. nice insights...

mate, I understand, I made a mistake, but only with good intentions and only because of my limited knowledge, not allowing me to distinguish crap from real potential. But pls. bear with my curiosity and try to shed some light for me regarding my question...

tks. for your reply. I don't even think of hoping tounderstand the relativistic Doppler effect, since relativity is not one of my forte's. The relativistic approach only "tweaks" the classical one, the one I have trouble grasping. If light speed is a constant regardless the reference frame, I...

I have not intended even for a second to advertise anything. I posted that particular link only because after a few hours of searching on the web some text trying to shed some light on the Doppler effect for ... light (for the layman, the one who has no idea of equations and so on), the only...

Forget about the link and its argument. Can you pls. explain in plain english the Dopppler effect for light ?

Did u ever try to explain Doppler effect for light in depth, at the photon level ? I'm no scientist. I'm trying to find a visual or mental representation of the doppler effect for electromagnetic waves. There is no medium to vibrate. No way I can understand the phenomenon by making a...

tks for your answer...I think you are right ...the author is probably referring to the ultraviolet catastrophe. could you pls enlighten me a bit more about this so called "catastrophe"? I have an idea about the phenomenon, but I can't say it's all clear... He (David Peat) writes later in the...

Hello ! I'm just a passionate reader of popular physics books. Often I'm in trouble understanding concepts and ideas. hopefully this time someone here will help me... I'm reading atm "From certainty to uncertainty", the book of David Peat. He mentions in the first chapter about 2 clouds that...

Tks. a lot tiny-tim. It's nice for me to be here and it's a nice feeling to know that there's a place where people are eager to help you clarify such ideas...

Hello ! In an article (Einstein's mistakes) published in 2005 in "Physics Today" by Steven Weinberg, he says: """""" even so, einstein would still probably be unhappy with today's theories, because they are not unified with gravitation and because matter - electrons, quarks and so on...
