"Write a javascript program that will allow the user to enter any random compound and the software will output it's theoretical transparency and draw a chart of its transparency over the various visible wavelengths. If the user does not enter a value the software will generate a random compound and calculate the transparency for it. It must be tested and verified to be accurate within 2.5% of 20 known compounds."

• This floored the Grok 4 AI engine sending it to dozens of websites. This is what it came up with:
• Whatever Grok comes up with looks like it could actually be significantly important, thus asking it to write a paper of the theory it has come up with would be apropos.
• After almost 9 minutes of working on the problem it generated a nice program - that did not work on real compounds, but artificial ones, it was thusly sent back to work on it more so that it had a real chemistry parser.
