Post memes here.
A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.
Laittakaa meemejä tänne.
When I was a kid I came up with this design during a long road trip. I spent the whole time thinking I was some kind of genius, because how didn't anyone else think of this before?
You can imagine my disappointment when I got home and created my prototype.
Equal AND opposite
Young lady, in this house, we obey the laws of thermodynamics!
Did you try flipping the magnet over? If you put the two north ends together they’ll repel instead of attract.
The beauty is that you can make the mental gymnastics to make it work both ways.
If they are opposite, the magnet attracts the car which moves the magnet away creating infinite motion
If they are the same, the magnet is repelled by the car, moving it away, moving the car forward creating infinite motion
You can even do mental tricks to make the contraption go backwards: Opposites: car attacks magnet which moves the car backwards Same: magnet reppels the car which moves the contraption backwards
By your though process shouldn’t the car be going backwards?
So mount it on the back and make yourself an old-fashioned rear engine car.
I tried something like that when I was about ten.
I still hold feelings against the force range being so short. Too close and the wire bends. Too far and there is barely any attraction...
Ugh, I just want to break physics, let me be.
Because you need to put it on the back and have it repel the truck forward instead of attract it forward obviously
The wire/metal holding it needs to be springy and bobbing back and forth to generate the momentum, duh.... Half-assed implementation I say.
It would work if the repulsion/attraction only went in 1 direction. But since it goes both ways, they just cancel out.
Conversely, the fan version of this idea (fan blowing into a sail) does actually work. But it's nowhere near as efficient as simply turning the fan away from the sail to push you the normal way.
What if u put the fan in the water?
There's oxygen in water, so it could work
Well because there the whole system now becomes the ship+air/water molecules rather than just the ship + you use energy to work the fan which imparts that energy to the air/water molecules. In the end the air/water molecules literally get pushed behind so the rest of the system can move forward.
Excellent! It is always nice to see people asking questions - the journey towards the answer should prove most enlightening! :-D
The magnet isn't strong enough.
If you ever talk to someone confused by this, maybe ask them to lightly push the front magnet in the direction it's trying to go.
I tried that, nothing happened to the picture. why???
Huh, try putting it next to the phone
Need a bigger magnet.
Also, how do they work?
Real, totally heavily simplified answer. All atoms could be magnets, but most don't have a force because the electron orbitals aren't out enough. In fact just about everything can be explained by what the electron orbitals are doing. Even why the chair you're sitting in feels solid. It's the orbitals. See and the deeper lesson on knowing the right questions to ask.
I love listening to Richard Feynman talk in those interviews
No, atoms with a symmetrical subatomic structure could never be magnets! And what would be the point of somehow enlarging the electrons orbit? You surely know a magnet needs a positive pole!
You are also definitely wrong about your third statement!You could never explain anything based on just the electron cloud, much less physics; a whole scientific field that generally works with the atomic core
they come from the ground so they have gravity in them
Miracles
I am pretty sure the other guy is talking nonsense and he kinda didn’t explain anything, its basically an atom with such a subatomic structure where there are more electrons on one side than the other, making that side more negative! The whole deposit is made up of atoms facing the same way!
“No srsly y isnt it?”
Why would it? Think about it, would the two magnet gets closer if the wheels started rolling?
Not with that attitude they won't.
Needs more magnets and some springs.
Maybe it needs gas?
This works in Kerbal Space Program
need two separate vehicles and two magnets, one weaker then the other
so the weaker one will repell the other and it will kick forward moving the other forward and rinse and repeat at a sonic speed
thats gotta generate some kinda motion
This is basically how a ~~rail cannon~~ coil gun works, just with electromagnets that can reverse their polarity.
It's a powerful way to accelerate anything — I think it's most famously used in those types of metal roller coasters that start you at a flat-with-the-ground angle, and then just fuckin launch you up a ramp to 45° with electromagnets. The issue is that you need a fuckton of energy to do that.
What we need for true perpetual energy is to just capture that guy Blanka from Street Fighter.
That's not how a railgun works, that's how a coilgun works. Railguns create a loop of electric current that flows into one "wire" (the rail), through the projectile into the other wire, and back down to the starting point again, this configuration creates a force that pushes the projectile down the rails
Ah, I appreciate the correction. I'm not an engineer but the youngest cousin of a clan of them, so I just got the highlights of the true evil genius shit. :p
