AI Thread Summary
To effectively block all types of waves, signals, and energies, the choice of insulation material is crucial, as different frequencies require specific screening techniques. Measuring and detecting these waves involves using specialized equipment tailored to the frequencies of interest, as well as identifying their sources. Certain signals, like gamma rays, can penetrate materials like lead if they are not sufficiently thick, highlighting that some energies may be impossible to completely block. The effectiveness of any shielding depends on the frequency and the required level of protection. For comprehensive understanding, researching terms like "Electromagnetic Screening" and "RF screened box" is recommended.

1. what type of insulation/material if a box is made of will protect in 100% effectiveness it's content from all type of waves/signals/energies that exist(anything you can think of or imagine) and that comes in contact with it?
2. how do I measure/detect all type of waves/signals(the exact types) that come in contact with that box and figure out their source?
3. are some signals/waves/energies impossible to be blocked no matter what material we put?

Even gamma rays will penetrate lead if it's not thick enough.
Longer wavelengths will cause finite currents to flow in the sides of a metal box and that can cause radiation to the inside.
The answer to your question depends upon the particular frequency you are interested in and just how much screening is required. Your question is far too open for a meaningful answer.
If you haven't read anything on the subject, this link could be a start. Use Google with search terms like "Electromagnet Screening", "EM protection" "RF screened box" etc. That will give you an idea of the sort of performance you might expect. Ditto for radioactive screening.

Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
