The future of BCI and VR according to Gabe Newell from Valve Corporation
– Valve is currently working on an open-source BCI software project, to interpret the signals being read from people’s brains using VR headsets.
– “If you’re a software developer in 2022 who doesn’t have one of these in your test lab, you’re making a silly mistake,”
– “The real world will seem flat, colourless, blurry compared to the experiences you’ll be able to create in people’s brains.”
– “BCIs have advanced to a point where that (VR) vertigo could be suppressed artificially, and that “it’s more of a certification issue than a scientific one”.
– Neuroplasticity is the ability of our brains to re-learn how to operate the body when something changes.
– “You can iterate software faster than a prosthetic”

What light is best to illuminate gems for resale
www.palagems.com/gem-lighting2
Artificial light sources, not unlike the diverse phases of natural light, vary considerably in their properties. As a result, some lamps render an object’s color better than others do.
The most important criterion for assessing the color-rendering ability of any lamp is its spectral power distribution curve.
Natural daylight varies too much in strength and spectral composition to be taken seriously as a lighting standard for grading and dealing colored stones. For anything to be a standard, it must be constant in its properties, which natural light is not.
For dealers in particular to make the transition from natural light to an artificial light source, that source must offer:
1- A degree of illuminance at least as strong as the common phases of natural daylight.
2- Spectral properties identical or comparable to a phase of natural daylight.A source combining these two things makes gems appear much the same as when viewed under a given phase of natural light. From the viewpoint of many dealers, this corresponds to a naturalappearance.
The 6000° Kelvin xenon short-arc lamp appears closest to meeting the criteria for a standard light source. Besides the strong illuminance this lamp affords, its spectrum is very similar to CIE standard illuminants of similar color temperature.
