Two other theoretical Physics researchers active in the early years of quantum mechanics were Louis de Broglie and Paul A. M. Dirac. (These two men also made additional contributions in other areas of Physics throughout their long lives.)
I have included a rather short Appendix at the end of this Post concerning these three great scientists, so I won't go into any additional details in the main body of this Post.
I wanted to make signature/avatar sets for de Broglie and Dirac that would be totally compatible (i.e., more or less in the same "style") with my Max Planck avatar, which was very simple to construct. The results are shown in the picture links in the "Images" section at the end of this Post.
The signatures consist of two Photoshop layers, the top "template layer" (which is identical for each signature) and the bottom layer (which changes in color for each and every signature).
The template layer, which is 277x73 pixels in size, is composed of:
a picture of Dirac on the left side, facing to the right;
a picture of de Broglie on the right side, facing to the left; and
quotations by both men in the middle of the picture (white "aliased" lettering was used, so that the words would be easily readable at the small size).
(It took quite a bit of research to find quotations from both men that were as "well balanced" as those shown in the image links.)
because the lettering, which is rather busy in itself, would get totally lost against a background such as this.
The avatars, like the signatures, consist of two Photoshop layers, the top "template layer" (which is identical for each signature) and the bottom layer (which changes in color for each and every signature).
The template layer, which is 91x59 pixels in size is composed of:
the text, THE MYSTERY OF MATTER AND ENERGY, on three lines, in all-capital white aliased letters (the same height as the capital letters in the signatures).
So, there is no doubt that this "setup" is very simple, but I feel that *very effective* signature/avatar sets can be generated by varying the background color(s).
In effect, then, this Post examines the relationship between the characteristics of the background "color fields" (color distribution, lightness/darkness variations, color "flow", etc.) and the elements of the topmost template layer (the border, the picture images, and the white text quotations).
I noticed that there is a relatively new MSFN member, whose member name is DiracDeBroglie. He is more than welcome to use -- (without any restrictions whatsoever) -- any of these avatars and/or signatures on MSFN or on any other of his forums.
Images 01 through 04 have solid-color backgrounds. These images are totally acceptable, but since they are not quite as "exciting" (IMO) as images 05 through 17 -- (which have color variations in the background) -- I'm putting them at the bottom of the list. Since my favorite signature/avatar pair is 08, I'm putting it first on the list. The background here was made using a simple blue-maroon linear fade.
08: blue-maroon fade background
These images are my favorite. I think the blue/maroon combination, dynamically speaking, works very well. The contrast of the hot (maroon) and cold (blue) is very effective. This look is somewhat unique on MSFN.
05: (light purple)-(darker purple) fade background
06: brown and gold background
07: dark to light blue-green fade background
09: brown and black background
10: teal, blue, and black background
11: purple, magenta, and black background
12: purple background
13: multicolored background
I don't like these two images at all. To me, the mixture of colors is rather "repulsive".
14: brown background
15: black and blue-gray background
I think these background colors are very compatible with the shades of gray in the images.
16: pink and blue background
17: blue and teal background
As I mentioned above, the next four images have solid-color backgrounds.
01: solid blue background
The blue works well with the white letters and images to give a feeling of "crispness". But, as a negative comment, I feel the blue is too "intense". (It kind of hurts my eyes to look at it.)
02: solid reddish-brown background
I like this image very much, in the way everything works well together. This image illustrates the fact that *simplicity* can be very effective (IMO). The reddish brown color is somewhat unique on MSFN.
03: solid turquoise background
I feel that this turquoise needs to be a little darker to have the most effective images.
04: solid blue-gray background
I used this background color when I reworked the avatar of jds (Joe). The blue component in the background makes the Dirac/de Broglie images (which are done totally in shades of gray) "pop out" a little more. As in 02, I feel that this image illustrates the fact that *simplicity* can be very effective.

Quantum theory was developed as a new branch of theoretical physics during the first few decades of the 20th century in an attempt to understand the fundamental properties of matter.
In contrast to Einstein's relativity, which is about the largest things in the universe, quantum theory deals with the tiniest things, the particles that atoms are made of (i.e., "subatomic" particles).
Max Planck (1858-1947), a German physicist, is recognized as the founder (in 1900) of quantum theory. He received the Nobel Prize in Physics for this work in 1918.
Louis de Broglie (1892-1987) was a French physicist who discovered that electrons have a dual nature, similar to both particles and waves (i.e., particle/wave duality). He was awarded the Nobel Prize in Physics in 1929.
With every particle of matter with mass m and velocity v, a real wave must be associated, related to the momentum by the equation:
lambda = h/p = (h/mv)(1- v2/c2)1/2
where lambda is the wavelength, h is the Planck constant, p is the momentum, m is the rest mass, v is the velocity, and c is the speed of light in a vacuum.
De Broglie's work created a new field in physics, wave mechanics, which united the physics of energy (waves) and matter (particles). For this work he won the Nobel Prize in Physics in 1929.
Paul Dirac (1902-1984) was a British physicist, who is characterized as "the father of antimatter". He won the Nobel Prize in Physics in 1933.
The positron -- (an anti-electron) -- has the same mass as the electron but opposite charge, and it was first detected experimentally in 1932. (This theoretical discovery of the positron allowed an explanation of matter/antimatter annihilation.) The anti-proton was first detected experimentally in 1955.
Dirac's research marked the first time something never before seen in nature was "predicted" -- that is, postulated to exist based entirely on theoretical rather than experimental evidence. (Dirac's discovery was guided solely by human imagination and mathematics.) For his achievement Dirac was awarded the Nobel Prize for Physics in 1933.
