for charged particles (so not for neutrinos) this leads the Cherenkov radiation, often observed in the cores of nuclear reactor: https://en.wikipedia.org/wiki/Cherenkov_radiation
as to why in this case: it can be somewhat intuitive to think that photons would be forced to take a somewhat longer path when traveling through a medium they interact with a lot (water, anything with a charge) then something which is almost going at the speed of light and famously doesn't interact with almost anything!
edit: Disregard the above, do I take my car or walk to a car wash 50m away
You're right that it's a bit confusing, as Wero's marketing is mostly focused on P2P transfer usecases, ie like US's Venmo/Cashapp, which as you note we can already do with SEPA transfers. Wero does have a small benefit in that case, as it's slightly more secure (you don't need to share your bank account, and there's a dedicated app that most Western Europeans will soon be familiar with).
The bigger benefit I think is as a unified e-commerce solution. While Wero is not directly an EU initiative, it's still supported by the EU commission. In general a good thing to keep in mind when evaluating EU financial/economic news is that one of the main things the EU tries to do is strengthen and protect their "single market": they want to make the flow of commerce within EUs borders as seamless as possible.
Having a unified ecommerce payment solution, so that you can eg just as easily order goods from German webshops as a Frenchman as you can from a French one (barring shipping etc) is in the EUs interest. Of course it's also in the banks that put forward this initiative's interest.
But, speaking as a consumer: this rules! iDeal is really nice, much nicer to use than credit cards or PayPal imo. I think it's easy to see why you would prefer a dedicated payment system in ecommerce rather than plain SEPA transfers (which most shops don't support) or credit cards, but in case that's not clear:
- Faster checkouts
- Don't need to share bank account numbers/sensitive credit card info
- Fees are much lower than credit cards (at least for iDeal its fractions of a cent per transaction: https://ideal.nl/en/ideal-fees)
- (Coming) built in support for subscriptions
Hope that gave a bit of an idea!
great job
every vegan should supplement b12, so they probably do too
The problem is having the submissions be in TeX and converting that to HTML, when the only output has been PDF for so long.
The problem isn’t converting HTML to PDF, it’s making available a giant portion of TeX/pdf only papers in HTML.
If you’re arguing that maybe TeX then shouldn’t be the source format for papers then I agree, but other than Typst (which also isn’t perfect about HTML output yet) there aren’t that many widely accepted/used authoring formats for physics/math papers, which is what ArXiV primarily hosts.
1. typst only really has pdf output at the moment 2. so much less tooling available (linters, site builders, converters etc) 3. much less of a markup format, extremely tightly coupled to a specific tool (typst compiler)
again, love typst, but it has (atm) so much fewer applications
