Saleh@feddit.orgto No Stupid Questions@lemmy.world•Can you have an infinitely long wavelength of light? Or is there some maximum?61·1 小时前I think your terminology is a bit mixed up. Light is a subset of the electromagnetic spectrum that we can see, plus infrared and UV often also being referred to as “light”.
As for the properties, they don’t fundamentally differ across the spectrum. The longer the wavelength, the less energy and the shorter the wavelength, the more energy.
As for the shortest theoretically possible wavelength, we are probably in the area of a Planck length
The Planck length is about 10-20 times the diameter of a proton.
Saleh@feddit.orgto Showerthoughts@lemmy.world•We should be able to legally have a different name just for work for better work/life separation9·4 小时前You can just ask people to call you by a nickname in your private life.
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.

The last thing Israel wants is a peaceful and stable Syria where people live together safely. The talks about “protecting” minorities in Syria is treacherous as Israel needs them to be perpetually under attack to justify its perpetual military presence.

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.
Saleh@feddit.orgtoMicroblog Memes@lemmy.world•so many apocalyses to choose from and yetEnglish21·15 小时前Australia also runs concentration camps for refugees on remote islands with practically no legal oversight. The Aborigines were considered part of the local “fauna” until the 1960s.
Australia gets way to less flak for how deeply deeply racist that country is.
Saleh@feddit.orgto World News@lemmy.world•China emerges from trade chaos with record exports and surplusEnglish42·1 天前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
Saleh@feddit.orgto World News@lemmy.world•Live updates: Trump threatens 100 percent secondary tariffs on Russia tradeEnglish2·2 天前The EU is not trying to “buy up Ukraine at a discount”, they are pushing for Ukrainian EU membership, which would be mutually beneficial. On the one hand, the EU would gain massive strategic food production and a large experienced military, and further buffer area towards Russia.
EU tried to get its own minerals deal with Ukraine in the wake of Trump demands.

Also Ukraine joining the EU would not make a “buffer”, unless you would argue in terms of first and second class EU countries, with Ukraine being designated to become a second class one. Ukraine currently is the “buffer” as it is aligned with the EU, but not part of it, so the EU does not bear the same responsibilities towards Ukraine as to other EU members.

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.

- 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.

Saleh@feddit.orgto World News@lemmy.world•To get their own cash, people in Gaza must pay middlemen a 40% cutEnglish212·2 天前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.

New USB bout to drop!3·2 天前It also is less energy efficient as running the juice directly through a cable of course is more efficient than creating a magnetic field that then induces juice on the other side to flow again.
It should be said that this is the principle of transformers, but they are built in an efficient way for it.
Saleh@feddit.orgto World News@lemmy.world•Clashes between Druze militias and Sunni Bedouin clans in Syria kill more than 30 peopleEnglish4·2 天前Note that countries like Israel, Turkiye, Iran, UAE and Saudi Arabia try to undermine unity in Syria and exacerbate ethnic tensions. In particular Israels tries to instrumentalize Druze and YPG/PKK Kurds to restart the civil war and prevent the emergence of a stable and peaceful Syria.
I think it was more of a bad flirting attempt
For how easy kicking is in DRG i found it to be used extremely rarely. One of the most chill game communities imo.
https://en.wikipedia.org/wiki/Light
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.
