Is ikr another subdomain?

Schools in the US often use an eTLD, "effective top level domain", which, although they have multiple levels, they are used as though they were a TLD like .com. The eTLD for schools is k12.{state}.us.

So if they use a www subdomain for their website, you can have lots of dots. I like these domains though, because they are generally unspoofable. You know for sure it's a real school domain if you see it.

Mozilla maintains the de facto authoritative list of these domains in a document called the Public Suffix List. That document has a real effect on how the Internet treats those domains.

You speak AAAAAAAA! too? Neat!

I read that as magnesium and was confused

I like this one.

It used to be really good, but they just kept on cluttering it over the years

It’s a shame what happened to it

I had a great periodic table on my wall in college. One spring break I took care of a friend's Caique during Spring break. By the time she returned my periodic table had been reduced to Hydrogen.

Wow! That's next level! Thank you!

Lots of good stuff posted here but personal favorite is the periodic table of videos periodic table of videos

They have a little 5-10 minute video about pretty much every element. Great way to know a little more than just the atomic number and mass.

Å!

Everyone should be able to do that! I'm studying political science and sociology right now and am enjoying it so much!

Maybe with automation and clever policy-making we can clear a path for something like this.

And I thought my high school with 3 subdomains was crazy

Well like with steel smelting. You need to add carbon to the iron making g process and they knew you needed charcoal and coal to get that going which is where I assume this comes from ?

Exactly. Horrible design, also the one in this post is exactly the same.

For real. It wastes too much space with useless info (% in universe, physical state) and buries or sometimes straight doesn't even include basic chemistry-related information like nuclei radius and electronic configuration.

Periodic tables were literally designed to be as straightforward as possible and this site decided to follow through the opposite.

I suppose it's only famous because it's easy as shit to type and hit enter (ptable)

Looks like a jawbreaker

And windy.com

This is beautiful. Thank you.

Just checking it out for the first time too. It is somewhere between horrible and godly.

I’m not completely sure what you mean but oganesson is the newest element on the periodic table, added in 2002 I believe.

I liked this one for magnetism https://labs.minutelabs.io/PeriodicTable/#mag

Yes, this is the one I use with my students!
