  1. Un des #paradoxes du #Québec: l'accès à l' #eau pour la #baignade est très limitée et souvent coûteuse! "Sur les 48 000 km de rives situées sont à moins de 200 mètres d’une route dans des zones habitées de la province, moins de 2 % sont accessibles. Selon les deux géographes, ces résultats « confirment l'existence d’un processus très avancé de privatisation des eaux publiques et une dépossession à grande échelle de notre héritage collectif" lapresse.ca/actualites/2026-07

  3. Zeno of Elea: The Philosopher Who Broke Motion

    The Devoted Student Born around 490 BCE in Elea (southern Italy), Zeno of Elea was the loyal defender of his teacher Parmenides. Parmenides claimed reality is one, eternal, and unchanging—that all motion and change are illusions. While others mocked this, Zeno set out to prove the opposite: that believing in "common sense" (motion and plurality) leads to logical contradictions even worse than Parmenides' claims.

    The Weapon: Reductio ad Absurdum Zeno perfected reductio ad absurdum: taking an opponent's view and showing it leads to impossibility. He constructed roughly forty paradoxes; only a few survive, but they have puzzled thinkers for 2,500 years.

    The Paradoxes of Plurality Zeno argued that if many things exist, they must be divisible. If you divide something endlessly, you either reach parts with zero size (making the whole size zero) or parts with finite size (making the whole infinitely large). Both are absurd. Thus, "many things" cannot exist. This anticipates modern debates about atoms and the Planck length.

    The Paradoxes of Motion

    The Dichotomy: To walk across a room, you must first go halfway. But before that, a quarter-way. There is no "first" step because there is always a prior midpoint. You must complete an infinite number of tasks to start moving—a logical impossibility.

    Achilles and the Tortoise: The swift Achilles cannot overtake a slow tortoise with a head start. By the time Achilles reaches where the tortoise was, the tortoise has moved further. The gap shrinks infinitely but never closes.
    The Arrow: At any single instant, an arrow occupies a specific spot. Since an instant has no duration, the arrow cannot move during it. If time is made of instants, and the arrow is still at every instant, when does it move?
    The Stadium: Moving objects in opposite directions create contradictions about relative speed and time, hinting at issues later addressed by Einstein.

    Legacy Zeno didn't just pose puzzles; he drove the development of calculus (to handle infinite series), refined logic, and forced physics to confront the nature of space and time. Even today, quantum mechanics (discrete quanta) and relativity (spacetime) grapple with the questions he raised. He taught us that reality is stranger than it appears and that "obvious" truths deserve the hardest scrutiny.

  22. CW: #2025 #Paradoxes - Using dissatisfaction anger for good things

    Trying too much can be a mistake too but I'm full of these paradoxes...

    I always try too much with people even though people prefer *thinking they know people* just because it's shallow-knowing type -

    So use I my dissatisfaction in the lack of depth as a kind of a problem (in people also) as a kind of fuel for other things...

    It's like knowing you'll be pissed off and people way behind in caring but not blaming everyone and knowing you'll be happy with non-perfect / imperfect ALL IS NOT PERFECT from the start (we have to know that from start and live with the crap).

    This "kind-of" works well to fuel other boxes in my life (maybe not other people's life as I hope they might repair it themselves) as long as you're not the type to explode and simply increment what you can in other things...

    People are also not flexible so year you can blame others and yourself... another kind of paradox...

    GRRRRRR..... ⬅️ :grr: use your dissatisfaction(s) to bring out the best beast in you!!! 🐻 🐺 🐿️ 👹 👺
