  • https://en.wikipedia.org/wiki/Light

    Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye.[1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively optical radiation.[2][3]

    In physics, the term “light” may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not.[4][5] In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization. Its speed in vacuum, 299792458 m/s, is one of the fundamental constants of nature.

    I didn’t know that some physicists choose such confusing terminology. Electromagnetic radiation is the more clear term and i have learned it as such in school, e.g. light being a part of the electromagnetic spectrum and generally speaking of electromagnetic radiation rather than light.





  • Maybe we could refer to places by when solar noon is for them in UTC.

    So that instead of knowing a simple +/- hours you have to first calculated it off of 12?

    I think it doesn’t make communication across timezones easier. Instead of everyone rolling with a comparable schedule and just adjusting for the time difference, you will have to remember many more local schedules as you lack an intuitive understanding.

    Also solar noon is even worse of a metric, because it would completely fracture timezones. Timezones already are a compromise, so that people in a more connected zone can work with each other more easier, effectively demanding the people on the east of that time zone to stay at work later and in the west of that time zone to rise up earlier relative to the sun.






  • This makes things way more complicated.

    When are timezones relevant? When dealing with people far away, or when traveling for longer distances.

    In the first case it is far more easier to remember that John is +3 ours from you and Julia is -2 hours, than to have to remember when John gets up and when Julia gets up, and when they go to sleep and so on. Remembering “about my shedule but +/-x” is far easier.

    In terms of flights it might seem easier at first, however once you land and realize that 13:40 means the middle of the night and everything being closed, you will quickly wish differently. Imagine for every further away place you visit you have to learn how the UTC translates to local opening hours, instead of just rolling with local time.



  • A weaker US will probably bring more stability.

    If we have a few, not too many, but a few power poles in the world, these powers will likely work to keep each other at bay. The US got completely unhinged after the fall of the Soviet Union. There was no one who could stop them after all. This lead to millions of people murdered by the US and its clients in the past 35 years. Bill Clinton’s presidency alone killed about half a million Iraqi kids through sanctions on food and medicine for Iraq in the 90s, ironically after the US, Germany and other western countries had been major factors in building Saddam’s chemical weapons and using them against the Kurdish minority and Iran. Then came the Iraq and Afghanistan invasions, again killing hundreds of thousands maybe up to a million of people. Libya tossed into chaos, Yemen as a genocidal campaign that the Saudis couldn’t have pulled off without US weapons, intelligence and assistance, killing hundreds of thousands again…

    US “liberal hegemony” has been the deadliest ideology in the world after Mao has died






  • The Suez channel is even more crucial to Israel than it is to countries like Spain or France for their link to East Asia.

    I have measured a rough example in maps:

    If a ship from Singapore to Marseille would go through the Suez Channel, it would be about 13,000 km without stops. Around Africa that would be around 22,000 km without stops (yeah i know that is optimistic), so a 70% increase which undoubtedly is bad.

    Now a ship from Singapore to Haifa would have its route increase from about 9,500 km to about 25,000 km, (again without stops) which is about a 170% increase.

    If the Houthis manage to effectively cut off that route, it will be driving prices up like crazy for Israel. If on top of it countries like Spain close the ports for ships carrying freight to Israel, it will further drive up their costs.


  • There can be various purposes to a ceasefire.

    • The most direct one is that a ceasefire gives a space in which diplomatic options can be discussed as both sides believe that there could be an opening where they gain more than with continued fighting.
    • The other direct option is that both sides believe that they can achieve a temporary ceasefire to rearm/regroup for subsequent fighting, believing that they can do so better than the enemy.
    • There could be external or internal political pressure to attempt diplomatic options, which will subsequently be derailed
    • There could be humanitarian reasons, albeit that seems to not be relevant these days, with humanitarian reasons being given as pretense at best
    • There could be religious reasons, such as the observation of a shared holiday, albeit that also seems to not be relevant these days

    For Ukraine as it stands there is little reason to believe that Ukraine will be able to retake their territory fully, unless the support from the West would come in the shape of boots on the ground and massive amounts of arms. As for Russia it seems Russia is slowly gaining territory while incurring high losses and taking very bad economic hits at home. So there could come a point of collapse of the Russian army. From Ukraines perspective however, unless that happens, if Russia gets weaker, they could always retreat to a reinforced line and take the gains they have made.

    Accepting defeat probably will not be taken lightly and will be the certain end to Zelensky’s rule, so i don’t think he’s to enthusiastic about a ceasefire. But it also seems that the Western Allies, in particular the US are not willing to give Ukraine what it takes and rather see an end to the war, with the EU countries probably following the US in trying to recoup some of the military spending by buying up Ukraine at a discount.

    For Putin on the other hand it is questionable, if he can sell the current state as a “victory” that justifies the losses. I guess for Russia to agree to a long term ceasefire they would demand to keep the current territories and be immediately relieved of sanctions.





  • Experts said it is unclear if the cash brokers’ activities benefit Hamas, as some Israeli analysts claim.

    The war has made it more difficult to determine who is behind all sorts of economic activity in the territory, said Omar Shabaan, director of Palthink for Strategic Studies, a Gaza-based think tank.

    “It’s a dark place now. You don’t know who is bringing cigarettes into Gaza,” he said, giving just one example. “It’s like a mafia.”

    The UN has reported on Aid trucks regularly being looted by the Abu Shabab gang. A group of lowlife criminals, who are armed and supported by Israel to wreak further havoc in Gaza and exploit the population further. In one of their largest raids, they robbed and burnt almost a hundred UN trucks for Israel in November 2024. I wouldn’t be surprised if Israel is funneling fresh cash to such criminal elements to further strengthen them and extract money from the people of Gaza through a middlemen allowing them plausible deniability. Note that the Abu Shabab criminals also have ties to ISIS. As Israel had consistently accused Hamas of “being ISIS” this shows once again that every Israeli accusation is a projection.
