  • Just to add to the wonkyness: not only is the active ingredient not a medicine, in many occasions it’s actually the virus or bacteria or whatever caused the disease. This gets dilluted to the point where it’s extremely unlikely that even a single atom of the original brew is present. And then they claim that the resulting liquid has a memory of losing the ingredient such that it has the ability to remove new particles of that ingredient (or something like that).

    It’s fantastically cartoonish and preys upon people who lack a certain understanding of logic.






  • Norawy is facing a similar issue. Even though the national identification number is 11 digits, the first 6 are reserved for birth date. The 7th digit has some set of rules derived from which century the birth was (something like 5-9 is reserved for year 2000 and beyond). The 9th digit is even for women and odd for men. The 10th and 11th digit are fixed and derived from the rest of the numbers.

    In conclusion, the system only leaves room for around 240 people per date of birth per gender (yes this system assumes 2 genders). So if the birth rate would have a spike, even just for a day, the system could be in trouble.




  • I’m also bothered by very detailed QR codes. Milk cartons in my country had a QR-code for their website. It would be a ~10 letter url, maybe with a short path. But for some reason, the QR code was extremely detailed, as if it contained several kilobytes of data. I’m not sure if there were a large number of tracking-related parameters in the url, but it was very obviously unreasonably large.




  • I hope I recall correctly: I was watching an episode of wan-show where they looked into a backpack returned from a miner after heavy wear, but little real damage. Live on the show they wanted to showcase the double bottom, so they cut into it (can’t recall if this was in the miners backpack or another one) and were surprized to realize there wasn’t a double bottom. Linus quickly assured, still live, that this would be handled for all customers.

    LMG did blame the manifactures of the backpack for removing a layer in a late stage design adjustment, but LMG have also alledegly taken a huge cost on assuring customers that they can receive a new backpack for free if the bottom fails for any reason.

    My memoery of this might be fuzzy, and the story I have heard comes fully from LMGs perspective, so take everything with a grain of salt.



  • But how do you apply this with Lorentz’ transformation (i.e. relativistic factors)? You cannot approach the speed of light without considering relativism. It is known that p = gamma * m * v where p is momentum, gamma is the gamma factor given by sqrt(1/(1 - (v^2/c^2))), m is mass and v is velocity. If you study the gamma factor, you’ll realize that it approaches infinite as v approaches c, the speed of light. Since we are actually dealing with light here, where v = c we are breaking the equation. Momentum cannot be defined for any mass which moves at the speed of light. It’s asymptotic at that speed.

    Also note that the same goes for E = mc^2. At relativistic speeds, also this equation needs to consider the gamma factor. So those classical equations break down for light.

    The answer is that photons don’t have mass, but they have energy. There is a good explanation a bit further up in this thread on how this is possible.
