What interests have you nailed or mastered or are good at?

So could rotary matter and antimatter make perpetual motion?

Some activities you can't measure what is "mastered" or "good"

For example, plenty of precious lil "people" told me that I should get published. However none of them know anything about the publication process. You can't measure quality. Maybe they were humoring me like I was a young child. (Patronizing ) they thought they were encouraging and kind. But "you can't make a silk purse out of a sows ear"

And you can't compare your outcome/score/performance to that of someone that never tried

Effort, efficiency, outcome

My defective carcass is a failure at everything I do

Just yesterday I tried to fart and a bowel movement came out

You almost have it right. Except you cannot do that for neutrons/anti-neutrons nor Z bosons.

The first set does not have electrical charges nor net magnetic forces great enough to be able to separate or keep separate with magnetic fields. This is one reason why we cannot make anti-atoms except for anti-hydrogen. We simply cannot yet contain anti-neutrons. As for the Z boson, it is it’s own anti-particle.

No, you would at best be able to contain anti-matter for a very short time. Absolute vacuums do not exist on Earth, which would be needed to contain anti-matter over long durations of time. Neutrinos and anti-neutrinos would still interact with it on Earth, causing effects as they annihilate with each other inside the void.

As long as they aren't loosing their kinetic energy or the universe is crashing is the answer to that is yes but in a simplifying theory only.

But of course there is a bit more to that because nothing in universe is absolutely separated from all other stuff and there exists Heisenberg's uncertainty principle and and there is mass in the fields of all particles which end in infinity so that there keeps a tiny interaction with all other particles in the universe and the room itself is not a constant and becomes changed too by the changing distance of matter and as you know is all matter in universe is moving and there remains even interaction with virtual particles of the quantum fluctuation of the vacuum...
Don't ever expect others to answer all your possible questions regarding that in a right way because even the brightest people don't know anything about the universe.

Does anyone else have things they’re good at?

I know that, and you know that, but he can't be taught.

There is another part that needs to be considered. Natural magnets are not strong enough to get the job done in containing bulk anti-matter particles, even special neodymium ones. The only way magnetic fields can be generated at a strong enough level on Earth is to use electromagnets. That is going to require either large constant flows of electricity through wires to create an electromagnet or super cooled superconducting materials (like those found in NMRs and NMRIs that use liquid He). Either process is expensive to do. If you want this to work cheaply, you will need to invent an room temperature superconducting material. That just is not going to happen in our lifetimes.

Disclaimer: As part of my job at the university, I manage an NMR that has a magnetic field strength of approximately 5 Tesla. That is powerful enough to stop a pacemaker from across the room. It costs our department about $25,000 a year just in liquid nitrogen and liquid helium to keep the superconducting coil cold enough to function. If the temperature goes above 4 degrees Kelvin, it will quench the magnet instantly.

Does anyone else have anything there’re good at?

Sorry to hear that. It's not a rare thing that otherwise bright people are wasting their time on such kind of stuff.

I don't really know what I'm good at. I suppose writing stories, although I struggle with producing a good vocabulary of various words, even if I use an online thesaurus.

I have a good creative mind and imagination though. But my imagination can stretch further than what I can financially afford, and I have things in mind that I could make myself but I don't have very good attention span or hand-eye coordination.

What has your interests been?

Are you sure? They have found the first material some months ago where a common fridge would be cold enough.

But of course it's not enough that it becomes superconducting but it has also to stay that in case of strong
magnetic fields and must be cheap and easy enough to handle for making wires of it.

It is a jump forward towards the goal, but still not at room temperature. The refrigeration of that material would require energy to maintain the superconduction, unless it is done at the arctic zones in the dead of winter.. The material created is very likely sensitive to the environment (that would need to be tested further), so that issue can be problematic for stability long term. I would love to see a stable room temperature superconductor. It would drop the price of maintaining NMRs and NMRIs by a large factor. I just do not see it as an achievable goal in the next thirty years.

^^ a material that makes a good wire is the usual goal in superconductivity, but I think the options would really open up if we looked for something that could be 3-D printed in a matrix with a supporting insulator.

I'm good at playing video games... lol

I am also good at taking pictures of things and cooking. My family always has me take pictures for them and I cook most meals now.
