  • Another fun fact: retinol is regenerated by your liver. Not your eyes, not some part of your brain, not some organ near your head like your thalamus which could probably get the job done if it tried, your fucking liver. Your eyes taking a while to adjust to the dark has basically nothing to do with your eyes; it’s because of the delay in adjustment by your fucking liver to produce more retinal, dump it into your vascular system and wait for it to hopefully reach your eyes.

    This is fascinating, I had no idea that there was another mechanism at play to improve low light vision other than pupil dilation

    I’m not supporting higher education becoming reliant on for-profit companies like this, but AI tutors and the like, if properly implemented, would be kinda awesome. For example, it’s usually not feasible to have real life staff on hand to answer student questions at all hours of the day. Especially at the more early years of university, where content is simpler, AI is more than capable of meeting needs like this.

    I don’t fully agree with most of the people on this thread. I also hate AI slop being forced into what feels like all aspects of our life right now, but LLMs do have some genuine uses.




  • This method uses magnetic resonant coupling (vs inductive which is how wireless charging works on your phone). The difference is the transmitter and receiver are both tuned LC circuits that operate at their resonant frequency, which is why this works over the impressive range shown in the video. It would have efficiencies around 80% mark based on what I could find. But yeah for RFI, this would definitely be worse than something like normal Qi charging, which operates in the 100s of KHz, while this operates in the MHz. But I think the manufacturers page says this is FCC certified? So might be not too bad.
