Most problems (including analytically intractible ones) can be modeled with a relatively simple monte-carlo simulation. Most simple monte-carlo simulations can be fully implemented in a spreadsheet.

Using timing coincidences in particle physics experiments is incredibly powerful. If multiple products from the same reaction can be measured at once, it's usually worth looking into.

Circular saws using wood cutting blades with carbide teeth can cut aluminum plates.

You can handle and attach atomically thin metal foils to things by floating them on water.

Use library search tools and academic databases. They are entirely superior to web search and AI.
