  • This hurts me so much: it's why I revert to text messaging because everyone has a phone number. The only downside is that you can't add/remove numbers to existing groups, so it can get out of hand quickly with the number of group chats.

  • Assigning big = better and small = worse is indeed a judgement.

    I think some people would argue that smaller growth = better since economies do better given slow change rather than rapid change, as rapid change might lead to rebounds.

    By even recognizing traits that seem similar across humans, we're isolating those parts of them while ignoring the richness of their being. It is objectification.

    But objectification is only detrimental when we assign judgements to what we compare. I'm not a woman so I haven't experienced the turmoil in those comparing breasts or other factors that men desire, but I am taller than average so I get the other end of the stick in how men are judged based on their height - often by women.

    Being short or tall has nothing to do with your intrinsic value as a human being, but there is extrinsic value created by those outside of us. I agree in that we should be prioritizing the former instead of the latter in society, which is why posts like this are problematic.

  • Yes, plants are autotrophs and can generate their own food from sunlight and the atmosphere. They still need some nutrients from the troposphere, like minerals, but they have it made.

    Heterotrophs are where things get wild

  • Just came across the Pinephone. Looks like they've figured out how to do modular wireless charging for their platform that still allows free access to the USB-C port, but this isn't compatible with phones that don't have pogo pins.

  • There are models out there that I've seen that have designed the cables to act more like bus bars that bend at sharp 90° in a flat strip profile, where the bend is less pronounced. But I agree that would be a failure point as time goes on to watch. I don't really remove my phone case all that often, so I don't think it'd be that big of a deal. They're like $10 total for a replacement off of Amazon, so price nor schedule is an issue either.

  • There are Qi adapters out there for phones without wireless charging built in. See this CNET article. It's not perfect, but a simple Google search says it's possible. Plus, adding this adapter and hiding it inside your phone case has the benefit of protecting your phone's charge port from dust and other ingress. I use wireless chargers for all my phone charging, so this is a viable option in case I ever want to go with a Fairphone or a Shiftphone (maybe even a Cube).

    The headphone jack thing is annoying. I'd buy their Fairphone 4 to have the option between wired and wireless.

  • Energy can be measured as occurring in different physical phenomena. There is energy in sound waves/packets, energy in light waves/packets, energy in matter, etc.

    The 300 MJ number refers to the electrical energy in the form of electromagnetic fields carried specifically through solid conductors via electron movement along the conductors.

    The 2.05 MJ number refers to the radiative energy in the form of electromagnetic fields sent specifically through free space/a vacuum (I presume; I didn't read the article, so maybe the laser medium was a vacuum or something else) via photons/waves. No electrons, aside from those in the lasers that create the photons in the first place.

    So there is a conversion from electric to radiative energy here.

    Start Edit:

    And as another commenter said, in this conversion there are losses because materials aren't perfect.

    :End Edit

    If the 3 MJ radiant energy from the nuclear material was then converted back into electric energy via steam processes, we'd get a comparable number compared to the 300 one.

    This is also why you see nuclear/CSP plants quoted in MWt and MWe: there is a conversion that takes place from thermal energy (vibrations of atoms/compounds) into electric energy.
