  • Here’s the thing: if you change the thickness of the layer then the colour will change along with it, but the material is otherwise the same. This occurs because the layers produce a phenomenon known as thin film interference. So it’s not the material of the coating layer that produces the colour, it’s the interaction between two layers.

    Anyway, you can see all of the colours of a light’s spectrum through a prism but you wouldn’t say the prism itself is any of those colours. It’s transparent and refractive. That’s all we have here with the glasses: refraction and reflection, with interference of certain wavelengths due to the exact thickness of the layers.






  • There are degrees of empathy! It’s a skill! A poker player may have enough empathy with you to be able to predict what you’re going to do based on the cards and the stakes. But they don’t know how you’ll react to a new pair of wool socks for Christmas from your aunt, the way your mom might.

    To know how a person will respond to a situation is to know something about that person. That is empathy. But many people can be in a marriage for decades without ever learning how their partner responds to every situation. In many cases this leads to divorce.

    Now, in that light you should see why I find it absurd when people claim to have empathy for everyone in the world. That’s like claiming to have Counselor Troi’s Betazoid powers. No one knows every person on earth, never mind knowing them as well as their own sister.

    To take one person as an example: Vladimir Putin. Intelligence agencies, military commanders, world leaders, analysts, and journalists everywhere spend enormous amounts of effort trying to understand how Putin thinks because human lives are on the line. Yet many of these people failed to predict some of the major actions he has undertaken because they don’t really understand how he feels, nor how many Russians feel. That is a huge failure of empathy brought about by a lack of experience and cultural understanding.









  • How often do you use it, if not every day? Once a week? Once a month?

    I use my laptop every day so it makes sense that I don’t use the power button even though it’s right there. I also have a raspberry pi set up to run Retropie that I only turn on once or twice a year when I have an old friend in from out of town. In that case I use the power button every single time but I don’t mind that it’s kind of finicky (I have to turn on several other devices with it as well as a power strip to power them all) because I don’t use it that often.

    I could see the new Mac Mini being a bit annoying with its bottom side power button if you’re using it every other day. But honestly I would be more annoyed at the boot time taking 30s than the 2s it takes to reach under the case and power it up. If I had one I would probably just get the keyboard with built in power button and finger print reader though. I use the finger print reader on my laptop all the time because it unlocks my password manager.




  • Vaginal birth isn’t always excruciatingly painful. It depends on the mother’s body type and health but it can also be improved with a proper birth position. Humans weren’t evolved to give birth laying on our back like in the movies, we were meant to give birth in a squatting position.

    Some women have even claimed that their vaginal birth was intensely pleasurable, causing them to achieve orgasm. Of course no one wants to hear this, as clashes with all sorts of taboos against women’s sexuality and giving birth in general!
