For a Dutch popular science book on string theory, I am looking for a good quality image of a hologram.
Some background info for who is interested (feel free to skip ahead
): string theory is a mathematical theory which combines the physical concepts of general relativity and quantum mechanics. An important concept in string theory is that of a duality, which means that there are two different mathematical theories that actually predict the same physical outcomes. Such dual theories can even exist in different numbers of dimensions - and so for example there are two-dimensional theories which perfectly describe three-dimensional situations. For obvious reasons, this type of duality has been labeled the "holographic principle".For the chapter in my book where I describe this concept, I am looking for a picture of an actual hologram. If someone has (or knows) an image that I could use for this, I would appreciate suggestions very much. Requirements on the image are:
- Large image size (preferably 1000x1000 pixels or better)
- Both the photograph and the hologram that is photographed should be free of copyrights (or at least, I need permission of the authors to publish it)
Of course, both the photographer and the person who made the hologram itself will be credited in the caption of the image.
Suggestions very welcome! Looking forward to your replies,
Marcel Vonk
