People who are arguing that one way of expressing these concepts is easier to learn/understand than the other are missing the whole point. Mathematical notation was not designed to teach students how to do math or explain how to design algorithms. It was invented to communicate precise, abstract ideas concisely between mathematicians who already understand what the symbols mean.
Mathematicians require a notation that has the flexibility to manipulate mathematical objects/symbols in a way that naturally emphasizes their properties and relationships. Often they don’t even care whether the objects they’re studying are even computable or have a numerical representation. They just need them to have certain properties so that they can be manipulated appropriately.
Discrete sums are a rare example of when the mathematical notation overlaps with the description of an algorithm for computing its value (and the overlap is not even complete; infinite sums are easily represented in math notation but are practically uncomputable when implemented naively). Every other advanced mathematical concept puts a premium on ease of symbol manipulation over computability: integrals, derivatives, matrix multiplication, abstract algebra, etc.
TL;DR math notation is complex because its intended audience is people who already understand it, want maximum flexibility of symbol manipulation, and historically didn’t really care about practical computation.
And now let’s look at our time units… leap years, leap second. A month has 28, 29, 30 or 31 days. A day has 2*12 hours. An hour has 60 minutes or 3600 seconds (Babylonian mathematics :) )
This is just a tram without the tracks? Guessing it is just for charging otherwise why not just have a tram which is much safer, more space and can basically drive itself
It has some benefits if they are worth or not I am not so sure.
It’s easier to change the routes, either permanent or temporally. In the case of temporally if it has a second source of power like battery or non electrical engine it can like use a non electrified street if there is some emergency or construction or whatever.
You can change routes for special days easily without junctions or whatever is needed for trams without big issues.
And even if it needs to electrify a new zone it, it probably much faster than the work for adding new rails and junctions.
Exactly, you don’t need to build tram tracks, and you can easily build routes uphill/downhill. I’m no expert on trams but I think it’s pretty complicated to have them go through versatile environments without having to build tunnel systems etc, so building a network that makes even more remote corners of a city accessible is much easier.
in North Africa they had 50 °C at the fucking sea. All the “you keep the southern African climate migrants in check for us” agreements the EU made, will not be worth much soon, when the people from Tunesia, Morocco and Algeria have to flee themselves from the heat.
This metaphor works very well with these two pictures. In the upper picture the more senior cattle are projecting the new and young. And in the picture below even they don’t even stand a chance alone.
And the same people who gripe about overhead cables apparently have no trouble staring at a street full of idling, polluting, and noisy cars. It’s really impressive.
Because diesel catching on fire is totally unheard of.
On it’s own? Pretty much unheard of. Usually is a leak and something else set it on fire.
Batteries on the other hand plenty of cases where the battery itself was the starting point. Is usually cause by a bad design or external factors? Yes, not saying otherwise.
And tbh Diesel is the worse example you could put as requires either high pressure or a continuous exposure to a flame as you could throw a lit match on it and it wouldn’t set it on fire. Petrol/Gasoline on the other hand…
I can only hope that this is trollbait. No sane parent would purposely ruin their children’s body (yes, it can be removed, but to do so you have to do a whole thing). On another note: what the heck’s wrong with having Zelda tattoos? I’ve seen the triforce tattoo on more than a few people. It looks cool.
