  • Not a better plan but just a curiosity as a physicist enthusiast.

    Regarding nuclear fission and nuclear waste (and ignoring the big elephant in the room that are nuclear weapons)…

    What are the technical difficulties to turn the radiation emitted by nuclear waste into electricity?

    I mean, if the nuclear waste is still radiating, it has stored energy that is radiated as photons, right?

    Then, we have the photo-electric effect which turns photons into moving electrons as long as the frequency surpasses a minimum threshold.

    Given that the radiation of nuclear waste has frequency way higher than UV, why can’t it be used to feed a photoelectric generator?

    Also, we have tons of nuclear waste, so the argument that a single rod doesn’t generate enough radiation seems kinda bogus since we could just store the nuclear waste into a safer recipient that turns the harmful rays directly into electricity and we have a shit-ton of them stored in thick lead or concrete barrels just so this radiation don’t harm the surroundings.

    .

    It is a genuine question that I had, but never had enough physics class to understand where this logic falls apart.

    Because, if it were feasible and “cheap”, I bet that the US would already be doing it and having access to “free energy” (not really, but a long-standing generator that doubles as removing nuclear waste from the ambient).

    Hear my idea:

    First we pollute the air enough to be almost unbreathable (as a side gig, we get to burn oil, coal steel…)

    Then we make special facilities to filter said pollution from air before said air enters the house.

    Then we sell these house for a premium with grade AAA+++ the best air quality ever.

    Now, what to do with the defective filters?

    Put in a house with grade B+ air quality.

    Grade C will be the houses that get the air that was exhausted from AAA+++ and B+ (after being breathed a few times and with no filtering).

    Grade F is the good old coal air that the people who can’t pay will have to breath as they work in the coal burning facilities.


  • Also worth noting that it is “everyone’s problem” as soon as US turns his military against other countries.

    For now it is Venezuela and maybe Nigeria,

    But here at South America we are “bracing for impact” even though we aren’t Venezuela per se.

    Trump already told he wants to annex Canada, Panama, Greenland and Vance already vented his distaste against Europe.

    It is just a matter of time before US turns against Europe.

    And then it will suddenly be a “World’s problem” because it only is a problem when the western civilization gets the wrong end of the stick.





  • old timers (or geeks) help me:

    Didn’t Rogue (which termed the genre Rogue-like) had a “monster capturing” mechanics? I know that Nethack has a pet system (you even start out with a cat or dog that follow, fight and even steal items for you).

    Also, what about older text based games similar to Zork? any of them with monter capturing/battle system?

    My point is that if we dig deep, we may discover “monster capturing” (or pet) mechanics way earlier than what most people think about what is considered the beginning of videogames (fliperama era games like NES, MegaDrive, Sega…)




  • I’m not a fan of Bolsonaro either.

    But my point was challenging the idea that the global view of US was high before Trump reelection.

    When the previous guy pointed that Biden was still following the political path of America’s warfare he wasn’t wrong to do so.

    No matter what party wins, US will be still an empire throwing their weight around (because they have nukes and because of dollar) and waging wars against any country who “dreams to defy US hegemony” (defy is a code word for not obeying US demands because US was always a Mafia Boss demanding a racket).

    The so called dallies, as trump has shown, are no more than countries hat happens to be closer enough to the Mafia Boss. But the Boss Uncle Sam will throw them under the bus as soon as needed to save his own life.

     

    Since you mentioned Bolsonaro, All of us, Brazilians who were not bolsonarists, saw that Bozo would betray any ally as soon as he got some heat on his back.

    The same applies to Trump, but, even more important:

    That was who US was as a nation all along.

    as Henry Kissinger said: ‘It may be dangerous to be America’s enemy, but to be America’s friend is fatal.’

    Downvoting anyone who denies the crimes of US under both republican and democratic presidency doesn’t change the truth value of this quote.

    Global views of the country, most importantly our allies were quite high and people were optimistic about American leadership.

    Here is the problem that you won’t be able to see.

    Such allies had a past of colonizing the “third world”, “Global south”, “non-western countries” or whatever labels kids these days use to label the “not allies”.

    My country, Brazil, was/is one that fought hard to really get a good global view.

    Though I’m not sure if we can maintain the good will of most countries if Trump decides to bomb just a little south to Venezuela (Which would hit Roraima or other Brazilian state, mostly) and start to call us narco-terrorist (and there was an attempt to do so).

    But still, to my point, It is hard to find any country who hates Brazil.

    For that reason I’d say that My country should’ve be used as parameter of (positive) global views given how known we are and how there is basically no bad blood between Brazil and any other country.

    Edit: Only 2 countries, Paraguay and Portugal, do have some animosity with Brazil.

    https://en.wikipedia.org/wiki/Anti-Brazilian_sentiment

    Paraguay is a “murky water” case because of wars around 1876. It is the closest that Brazil has as current diplomatic dispute, but similar to almost all (non-military) border disputes around the world.

    or even better, set a pomodoro.

    Maybe even on easy mode (5 or 10 min) to bootstart studying, let it ring once, nod at the pomodoro and keep in the flow.

    Or… if you felt a strong urge to not study in these 5 or 10 min, nod at the pomodoro and says “Thanks Cthullu I’m free from this time prison!” and move on.

    I personally hate doing pauses with pomodoro, so I just use it to make sure I did at least one pomodoro unit of time of whatever the fuck I planned to do (But I do pause once I start hitting a wall or getting tired)
