    B Exploring Animal Electricity: The Fascinating Discovery of Galvani in 1771

    Thank you for your kind words. Also, your question was kind of a non-question as it was reposing my question to me. I would not be asking if I knew the answer.

    B Why was the name Higgs given to the boson?

    In 1964 three papers were published, Why was Peter's name chosen for the boson? Who chose it? 1) Belgian physicists Robert Brout and Francois Englert Physical Review of Letters, Volume 13, number 9, August 31, 1964, Pages 321-323...

    B Exploring Animal Electricity: The Fascinating Discovery of Galvani in 1771

    I have read that in 1771 physician Luigi Galvani notices that the leg of a dead frog moves when being explored by metal probes. Galvani called this “animal electricity.” Why does he think that this movement has anything to do with electricity?

    How Did Stephen Gray Conceptualize Sending Electricity Through a Wire in 1729?

    I have read that in 1729 Stephen Gray, in addition to generating static charges, sends, for the first time, electricity through a wire and coins the words insulator and conductor. What does he think he is sending though the wire, there is not yet a concept of atoms or electrons as we know them...

    I Solving the Gravitational Field Equations

    I have read that: In 1915 Einstein presents to the Prussian Academy of Sciences the General Theory of Relativity; it includes a set of Gravitational Field Equations; at this time he does not present any solution to the equations. In 1917 he considers a greatly simplified case; presents a...

    Maxwell and the speed of light

    Einstein said that the speed of light is constant for all observers. When Maxwell derived that the speed of light in the ether was 299,792,458 m/s could he or did he surmise that the speed of light is constant for all observers (regardless of the motion of the source)?

    Why is it called the ultraviolet catastrophe?

    Thank you for your kind words.

    Why is it called the ultraviolet catastrophe?

    Why is it called the ultraviolet catastrophe rather than the visible catastrophe or the microwave catastrophe?

    Why do we observe only microwaves in the background radiation?

    If the background radiation that we see today were in the visible range (for example red), would the night sky be red instead of black?

    Why do we observe only microwaves in the background radiation?

    Why aren't the other bands (visible, UV, etc.) in the electromagnetic spectrum also seen today as part of the background radiation?

    Who Won the 2013 Nobel Prize in Physics and Why Not Others?

    The 2013 Nobel Prize in Physics was just awarded to Francois Englert and Peter W. Higgs. Why were they chosen over Robert Brout, Gerald Guralnik, Richard Hagen and Tom Kibble who published similar results at about the same time.

    The correct pronounciation of de Broglie

    Is this correct? http://upload.wikimedia.org/wikipedia/commons/3/34/De_Broglie.ogg

    Entanglement Hypothesis by de Broglie in 1935

    I believe that it was de Broglie who hypothesized that two particles could become entangled and in 1935 Schrödinger gives it the name. Can someone point me at the the publication in which de Broglie did his hypothesizing or at least tell me the year.

    What is the effect of photon-electron collisions in X-ray imaging?

    My understanding is: A) If a photon strikes an atom and the photon has exactly the correct amount of energy to move the electron to the next (another) energy level, the electron will absorb the photon, the photon will cease to exist, and the electron will move. B) If a photon strikes an atom...
