    Re: On-chip micro-sized lens created by UD researchers

    Now, if you can go deeper and affect the spin and orbital momentum of the light as well as wavelength and whether it's on or off, imagine the bandwidth potential.

    I had some equations in my notebook about this but I couldn't get my head around them.

    So I wrote them on a random whiteboard at work. Someone solved them. No idea who.

    EDIT: They also put a note to stop writing random black hole equations on their whiteboard. Which was quite amusing as you can work out out if light has been past a black hole by the angular momentum.


    ...So I left them with Hawking's rate of evaporation of a black hole equation. I still don't get how you can use any derivative of Planck's Constant (h-bar) in this when you're beyond the event horizon which is where this equation operates. I didn't get an answer.

    I've been drinking again. Plus I've not been out of the house for several days and I'm going stir crazy.

    Quite probably the strangest comment ever. Congrats Phil!

    Yeh, I take my evening meds, the pain goes away and then I start drinking and babbling astrophysics.

    Studying the effects of my meds on my brain is really interesting as there are so many different ones affecting different systems. I did several IQ tests (proper ones) on different meds for fun. The difference in my IQ between fully medicated and not medicated is 32 points. I forget which way round though.... I think I was too medicated to remember.

    I was drunk enough to send that question to an observatory.

    We'll see if they respond.

    In the sober light of only one beer, it's a good question.

    Gah! I knew it was etched dielectric materials! Seriously though, where's my "eh!?" emoji

    Love these mad boffin articles. They go way over my head but are fascinating. And strangely, they make some sense too.
