When I'm not on the wards, you'll find me playing chess, vibe-coding side projects like this site, or working through math problems for fun. I have founded a software company named "Bolteryx". Currently I am the CEO of this company. I have firm interest in charity work. Go through this site and you'll find what I did.

A quick reference search for students, teachers and curious minds. Canonical URL: https://msbsu.com/tools/science-search Math & Science Search puts three references in one box: NASA’s image and video library, open research papers from the CORE index, and number facts. Search for a nebula, a mission or a topic like quantum computing, or type a number to find out what is interesting about it. Uses this site’s server to fetch data, so you need to be online. ## How to use Math & science search 1. Choose a source: NASA images, research papers or number facts. 2. Type a search, for example “Apollo 11”, “CRISPR” or “1729”. 3. Open a result to see the full image, the paper’s details or the fact. ## Frequently asked questions ### Are the papers free to read? Results come from CORE, which indexes open-access research, so most papers link to a free full text. ### Can I use the NASA images? NASA imagery is generally not copyrighted, but check each item’s credit line, especially for images from partners. Feeds bring outside knowledge into one place: Wikipedia’s historical records for any date, NASA’s media library, open-access research papers from CORE and number facts. Results are fetched live when you search, so you always see current data.
