    Undergrad What are the speed limits of a maglev track?

    I think a MagLev track on the Moon could launch objects into space. But not on the Earth because of air friction.

    Geiger Counter Question

    Why would you worry that the instrument might be contaminated? It sounds like the count rates you got were normal background levels.

    Undergrad Exploring the possibilities of storing electricity from lightning

    @couperusfred, please learn to use capitalization and punctuation in your writing. Your stream-of-consciousness posts are very hard to read and most people will not take them seriously.

    Undergrad Exploring the possibilities of storing electricity from lightning

    One way to look at it is that the energy in a lightning bolt is about 1GJoule or 1,000,000 1,000,000,000 Joules. This is equal to about 275 kWh, and so is worth about $50 if you could harvest it all (very unlikely). How much do you think it would cost to build a vehicle that would drive around...

    Chestnut Trees Coming Back?

    That would be wonderful if they could succeed. The old pictures and paintings show large stately trees with a huge spreading canopy. The wood was also very beautiful.

    Undergrad Can nested solenoids trap particles?

    Oh yes. Helion energy is banking on it. They started construction on a power plant in July, 2025. Whether they will succeed is anyone's guess.

    Undergrad Can nested solenoids trap particles?

    I think what you are talking about is similar to the field reversed configuration, which is being studied as a possible path to controlled nuclear fusion.

    Automotive Need to glue aluminum to glass

    I'm surprised to hear this. Silicone rubber sealant in a shower bonds very well to galss, ceramic tile, and many other things, and stands up to hot water in a shower for years.

    Automotive Need to glue aluminum to glass

    I would try silicone rubber sealant.

    Graduate How to compute the path 3i/Atlas will take when it passes near Jupiter?

    Why do you care if it passes slightly inside or slightly outside of the Hill radius? It won't make any significant difference in its orbital path. Either way it will continue on its way and exit the solar system.

    Is A.I. more than the sum of its parts?

    I'm missing your point here. You think that there is some unknown component in the brain?

    Is A.I. more than the sum of its parts?

    I'm always confused by the argument that says, "they are just machines, they can't be intelligent/conscious." Your brain is a collection of biological neurons, and it is clearly intelligent and conscious. So why can't a collection of artificial neurons, which in many ways mimic the neurons in...

    Graduate How to compute the path 3i/Atlas will take when it passes near Jupiter?

    So the JPL websire you linked says that Atlas-3I will pass within 0.358 AU of Jupiter. You want to independently verify this? The orbital elements of Atlas-3I are given, and the orbital elements of Jupiter are listed elsewhere at JPL. How familiar are you with orbital mechanics and how to...

    Is A.I. more than the sum of its parts?

    I think it's not true that current LLM's are deterministic. They all incorporate some level of stochasticity.
