    Paper lets the flour breathe, releasing moisture. The grain isn’t 100% when milled and the milling process generates significant heat (mill some grain at home with a motorized mill and see). Warmth + moisture + hermetically sealed plastic smells like a nice way to grow some fungus.

    Edit: isn’t 100% dry when milled.


  • I get that people like to be stubborn about this but there are very real and intuitive reasons that decimals don’t make sense everywhere. Consider how intuitive telling time using “kiloseconds” and decimals might be.

    The right tool needs to be used for the right job. I am a scientist. In the lab, metric is fantastic as it allows for precision recording and I don’t care about intuition.

    It’s not a point of pride to use one system over another. For example, in America we use both systems in the right contexts. I am happily able to fluidly switch between what’s most appropriate for the situation. I get that context/code switching is generally difficult but I think it’s an overall value add.





  • Special relativity definitely overlaps with quantum mechanics and that overlap forms the basis of the math used at collider experiments like those at the LHC. Special relativity is simple with 2 rules that let you derive all the equations: 1) no universal reference frames 2) speed of light is constant.

    You’re probably thinking about general relativity which defines gravity through the curvature of space time.

    If you think about quantum mechanics existing on some “canvas”, that might look like an interlocking mesh of springs (like something under a bed or cot). You could take your hand and bounces it up and down on this mesh, adding oscillations and creating standing waves in the grid. These oscillations would be different particles (electrons, protons) each with their own characteristic frequency of oscillations. If you add energy to the bed of springs, you can “pop” particles into existence. All these particles actually are are just excitations of the mesh/canvas. As of yet, there’s been no way to define or find the gravity particle on this canvas, so right now the canvas of space time and the canvas of quantum mechanics are two distinct “things”.














  • Thinking about this more , you probably want this to develop a curve in your color space that represents something with constant CMYK values for your chosen light source.

    https://python-colormath.readthedocs.io/en/latest/conversions.html

    E.g. your sodium light is 100% yellow, 10ish % magenta. Any color that varies cyan from 0%-100% and black from 0%-100% should presumably not reflect any additional color information (since the source light doesn’t have any cyan and black is just giving brightness)

    I also think this means that as long as you hold Y and M constant, you can vary cyan and black for your comparison colors that will look the same. If you try to vary cyan and yellow or magenta at the same time then your effect probably won’t work.

    This is tricky because you have multiple curves in the color space that are valid when just considering a single wavelength. The reality is, your lamp emits a spectrum of light (sharp, but still has a width). There’s also the variability in perception. But I’m not sure what the “bandwidth” of our eyes is and what color resolution humans are capable of detecting.
