15yearold did mathematical research?! What was my thinking process back then?

The unsolved math problem which could be worth a billion dollars.

History
Eric W. Weisstein, the creator of the site, was a physics and astronomy student who got into the habit of writing notes on his mathematical readings. In 1995 he put his notes online and called it "Eric's Treasure Trove of Mathematics." It contained hundreds of pages/articles, covering a wide range of mathematical topics. The site became popular as an extensive single resource on mathematics on the web. In 1998, he made a contract with CRC Press and the contents of the site were published in print and CDROM form, titled "CRC Concise Encyclopedia of Mathematics." The free online version became only partially accessible to the public. In 1999 Weisstein went to work for Wolfram Research, Inc. (WRI), and WRI renamed the Math Treasure Trove to MathWorld and hosted it on the company's website^{[citation needed]} without access restrictions.^{[citation needed]}
In 2022, Mathworld WVR was released on the Oculus, "Each mini game in Math World VR combines simple math that adds a fun challenge".^{[4]} In 2023, Mathworld VR added new mini games. The games combine math arithmetic that makes math, fun.^{[5]}^{[6]} The game can be played on the Oculus Quest, Quest 2, and the Meta Quest Pro virtual reality headsets.^{[4]}
CRC lawsuit
In 2000, CRC Press sued Wolfram Research Inc. (WRI), WRI president Stephen Wolfram, and author Eric W. Weisstein, due to what they considered a breach of contract: that the MathWorld content was to remain in print only. The site was taken down by a court injunction.^{[7]}
The case was later settled out of court, with WRI paying an unspecified amount and complying with other stipulations. Among these stipulations is the inclusion of a copyright notice at the bottom of the website and broad rights for the CRC Press to produce MathWorld in printed book form. The site then became once again available free to the public.^{[citation needed]}
This case made a wave of headlines in online publishing circles. The PlanetMath project was a result of MathWorld's being unavailable.^{[8]}
