If you want to get into the mind of Tesla a bit I highly recommend "My Inventions", his sort of autobiography where he described how his mind worked. He spent a lot of time developing his imagination at a young age and "traveling" in his head. I was surprised to read that he would visualize entire designs in his imagination and then go through prototypes and iterations several times before bringing that idea into the…

Doesn't everyone do this? I remember at the age of five finally learning to control my falling dreams at night, to be able to freeze in the air and eventually fly (the Matrix scene definitely resonated later). This was the beginning of a continuous exercise of imagining things more and more exactly and controlling that imagination. Now as an engineer, I spend most of my time staring at a wall simulating and refining…
To a certain degree yes - it might depend on how well you really understand something. I also feel like this is a unique aspect of humans - to be able to anticipate / simulate cause and effect. I find with certain sports once you get the hang of it you do this. For me with aggressive inline skating I might imagine a lineup of tricks, getting the feeling for it before attempting the tricks. For boxing you can start to…
I would describe that levitation trying like trying to move a paralysed limb. Like we had neuronal circuitry required for levitating, but it doesn't work anymore. Human senses interpretation is wonderful thing. You can even see through tongue or skin on your back (with electrode array connected to camera).

> Doesn't everyone do this? I wish I had the ability of imagination like you describe. I don’t think I have full-on aphantasia ( https://en.m.wikipedia.org/wiki/Aphantasia ) but I definitely can’t run simulations in my mind.
I do have aphantasia, and until reading about it a couple of years ago I had no idea most people meant it literally when they talked about seeing things in their mind outside of dreams. I can describe things in detail based on spatial relationships very accurately with my eyes closed, but at the very most I sometimes see vague subsecond flashes.
Cheekily, I sometimes claim I have no need to close my eyes when I think, so I can work simultaneously from what's modeled in my head.

Ask how many developers visualise their design in their mind before they type a single line of code.
Because this offers different obstruction levels to different rates of flow and because it works in one direction could it somehow be used to create a version that could operate like Maxwell's demon with particles with a certain temperature rather than a fluid? Temperature being a mscroscopic measure of the microscopic velocities of particles.

Where temperature affects density or viscosity, there would obviously be applications of any technology that changes function as inertia or viscosity are modulated. But I don't think there's anything about this valve that would unlock the key to violating the second law of thermodynamics.
It would also be cool to etch like a single-atom-wide version on some substrate and see what would happen with particles you put in there :p ;) xx

You may be exceptional. In my experience, it often works / looks perfect in the head. But putting it to paper, it falls apart quickly. Imagine a bicycle, it is easy to imagine it accurately. Then draw it (or construct it), one usually struggles a lot. The step to materialize it, is where you need a lot of practice. The worst are the the "idea" guys. They think they have already done all the work, and somebody else ju…
I imagine it will vary widely depending on the complexity of something. The more complex something is the more likely you fail to predict some things accurately, so based on this conversation it's difficult to tell whether someone is exceptional or not, as exceptional would be when you are able to do more complex designs accurately than most other folks.
It might be the way my mind works but for me I "feel" the parts more then see them.
But I can't visualise with accurate dimensions, and for me I find that matters a lot in terms of manufacturability.
Even very simple designs I usually end up making several iterations on paper or in cad. It's only after dimensioning, doing some basic calculations (say, will this bit be strong enough), matching to available stock and parts, double checking the tooling I have to make sure I can actually make the things I've drawn, looking for interference and so on that I know what the design is really going to look like.
People who are really good, I think, naturally design parts to minimise setup time and with the jigs and workholding they'll need to make them in mind. I'm not there yet... I still snooker myself on workholding or order of operations reasonably often.
My headphones apparently use them as part of the cooling system: https://www.nuraphone.com/backstage/how-the-nuraphone-uses-m...
How are the Nuraphone cans with sound leakage? I've had hearing issues since childhood and tend to turn the volume WAY up. Nuraphone has been on my radar for a while, but I exclusively buy headphones with as near-to-zero external leakage as possible, since I don't want to piss off my co-workers with audible music.

That's fascinating, I'd never heard of those! I'm still looking for the 'perfect' wireless headphones, so I'll definitely research them some more. How is their sound, in your experience? And is the cooling effect actually noticeable?
They’re good, I think the demo/test they do if you try them in person or after first setting them up is really disingenuous. They’ll tell you is the mid point of all profiles, but it sounds muddy and like no headphones I’ve ever heard. Customise them though and everything sounds amazing.
Where it got interesting for me though I’d have a few friends customise and setup their own profiles and they’ll report the same thing. Yet switch between each other’s profiles and you think everyone else’s sounds like trash too. So to me it seems clear the customisation is definitely working and highly personalised.
All that said I couldn’t say with confidence I’d immediately notice the difference between them and my Bose QC unless I was switching back and forth and testing them side by side. For daily use I’ve found most headphones in that price range to be great. For long haul flights the Bose still win for me. I find the in ear and over ear combined designed of the Nura to be very uncomfortable after 10hrs. Any shorter time and the Nura are my goto now.
I was impressed enough that I recently bought a pair of Nuraloops for running too. I don’t think they’re as well designed. They’re difficult to fit, difficult to keep in, and ultimately I had to get aftermarket Comply ear tips to have them be in any way usable. They’re fine now, but I expect I’ll have to be replacing ear tips monthly at this rate which isn’t what I expect for a product at this price point.
