This soldiering training is the most impressive and immersive I've ever tried. It is 10x better than a YouTube tutorial video. It really allowed me to see the procedure from all the points of view, and even get super close to get the details. It is a collaboration between Gracia and Imperial College London: they recorded a soldering session with Gaussian Splatting Videos (4DGS), so that you can enjoy it from your VR headset. You can see the action happening in front of you; you can pause and re-watch what you need, change the point of view, get closer, get more distant. And the quality with which it has been shot is impressive: I enjoyed this experience with my DELL Pro Max Tower T2 with NVIDIA Pro RTX 6000, and I could really see all the small details of the PCB that was being soldered! I was really impressed by it. But I also noticed some drawbacks. First of all, some scenes have artifacts that make seeing the details of the PCB hard. I think when it comes to training involving small details, the capture and reproduction of the splat should be flawless. Then, as much as I loved it as a passive experience, I would have liked to have also some sort of practice session in VR. The power of VR is to let you learn by doing in full safety, and this kind of training does not exploit it. But maybe the best way to enjoy it would be in MR, where you have this training video close to a real workbench where you do the actual soldering while following the tutorial. Gaussian Splat can really revolutionize training: this kind of recording is much better than any flatscreen experience, and more accurate than any 3D CGI recostruction. I suggest you give it a go at this experience in the Gracia app (it's free). Then let me know your impressions! #VirtualReality #training #DellProPrecision #GaussianSplat #technology [Disclaimer: I'm a DELL Pro Precision Ambassador, and this is why I mentioned the model of my PC.

Where is the triangle? Alex O'Connor thinks consciousness is the one thing materialism can't explain away and he has a deceptively simple argument for it. Close your eyes. Picture a triangle. You can see it. The shape, the angles, maybe even the colour. It's right there, vivid and undeniable. Now ask yourself: where is that triangle? According to Alex, this single question cuts to the heart of one of philosophy's oldest problems. A strict materialist, someone who believes everything in the universe reduces to physical matter has to say that triangle exists somewhere in the neurons of your brain. But if a neurosurgeon cracked open your skull right now, they wouldn't find a triangle anywhere inside. "If everything you experience is reducible to the material when I close my eyes and see a triangle, there really is a triangle there. I can see it. It's there. And I think well, where is that triangle? The materialist has to say it's reducible to just somewhere in your brain. But if I cut open your brain I'm not going to find a triangle inside of it." He anticipates the obvious pushback. When he raised this on YouTube, commenters pointed to computers as a counter-example: if you cut open a computer, you won't find the triangle it's displaying on screen either. But the hardware is still producing a real image on a real screen. Alex's response is that this analogy doesn't hold because the mind has no screen. There is no separate interface between the brain's processing and the experience of seeing. The brain is the computer and the screen. Which only deepens the mystery: somehow, purely physical processes are generating a first-person, subjective experience: colours, shapes and images that can't be located anywhere in physical space. "It's as if the computer itself somehow had a triangle in the computer's own first-person subjective experience. Like where is that triangle that you can picture in your head? Where the hell is it?" For Alex, consciousness isn't just another interesting puzzle in the philosophy of mind. It's the big objection to materialism. The thing that, once you sit with it, seems to demand that there is something more going on than matter arranged in clever ways. He points to something as ordinary as dreaming as a case in point. Every night you produce vivid images full scenes, faces, colours without any external input. An entire visual world conjured from nowhere. Where does it come from? Where does it go? "Even just when you have an average dream, it's fascinating to think what's going on there. You've got images in your head, you can close your eyes and you can picture things, you can see colours, you can see shapes in your head. Like where are those shapes?" The triangle thought experiment has a way of making this undeniable. It's not abstract. You can do it right now. And when you do, you run headfirst into the hard problem of consciousness: the gap between the physical description of the brain and the felt quality of experience that no amount of neuroscience has yet bridged. Whether you find Alex's argument convincing or not, the question it raises is genuine: how does purely physical matter give rise to the inner world we each inhabit a world of colours, shapes, memories, and dreams that exists nowhere except in the first person?
