- amjd 5y agoI have fond memories of this site. I used to refer to it extensively when I was in high school a decade ago. It's a great resource.
- prpl 5y agoI used it a bit before that (2004-2006) but it was a great resource and then Wikipedia started really coming along. I think that now, however, it is a better resource than wikipedia when I want to double check something because of the simplicity as wikipedia articles have expanded quite a bit even on simple things.

- aqualinux 5y agoLove the fact they haven't updated the website to more modern web technologies.
- xmprt 5y agoDo you love it purely for nostalgia? Because I loved this as much as you back in the day, but this website could definitely use some improvements to make it more accessible and palatable to students today.
- dekken_ 5y agosome centering would be nice
- NL807 5y agoI'd wager all they need to do is get some proper CSS happening and they can visually change things without intrusively changing the HTML content itself. The may need to strip away some deprecated attributes for HTML elements, and add class attributes, but that's about it.
- saeranv 5y agoI love it because it loads quickly and isn't more complicated then it needs to be.
- xmprt 5y agoI'd argue that using all those images and maps instead of svgs probably makes it load slower and is more complicated than it could be.
- II2II 5y agoIn my case, there is a definite nostalgic bias. I would have used the site near the start of my university studies in 1996. That said, I think there is a case for leaving it as-is. Many sites are designed to be accessible and palatable to students today, so there is some merit to maintaining the original style in case it addresses the needs of people who are not well served by modern sensibilities.
- danwills 5y agoI was keen to explore (even if it's a bit dated) but unfortunately the combination of mobile-browser and dark mode makes a bit of a mess of things.. (making it quite a bumpy ride) I wonder if there are any 'translations' to other formats around? "Second Law of Thermodynamics: In any cyclic process the entropy will either increase or remain the same." I need some clarity about what is meant by 'cyclic' here. Is it perhaps to refer to feedback loops/self-sustaining phenomena?
- filmor 5y agoA cyclic process is a thermodynamic process that eventually arrives back in its initial state: https://en.wikipedia.org/wiki/Thermodynamic_cycle https://en.wikipedia.org/wiki/Thermodynamic_cycle
- danwills 5y agoThanks, had a read and I think I understand approximately. I am still wondering whether biological systems should count as cyclic in this sense too? I think that they seem to, in the returning-to-the-same-state thing, at least across the generations, and even in regular metabolism in some sense - but the law doesn't (intuitively) seem to apply in the biology/evolution case.. it doesn't just diffuse, it can go on in pretty much precisely the same pattern for billions of years it seems? I guess I am probably ignoring something huge about this (like the Sun!?)

- streamofdigits 5y agono, cyclic in this context means that all macroscopic system variables (temperature etc) return to their initial conditions
- eurasiantiger 5y agoFunny, I wasn’t aware we were aware of the initial conditions of the non-onservable universe.
- streamofdigits 5y agotrying to think if there is any reason to use image maps instead of svg. maybe slightly easier to generate programmatically the page
- milkey_mouse 5y agoThis site probably predates SVG, or at least its widespread support!
- PennRobotics 5y agoIn short, image maps work(ed). The author, Rod Nave, is old, possibly retired, and probably self-taught in HTML 3.2. Image maps were the modern tech in the years after Fulton County started pushing internet to residents---1995 or so. I don't remember there being any alternatives at the time; CSS was mostly supported by many browsers, but div tags weren't in widespread use. For a non-programmer, it would be a herculean effort to learn and transition existing material to a new technology, and the benefits might not be obvious to someone focusing on teaching physics to 100 undergraduates most of the year and seeing the widespread, positive impact of the current implementation.
- quaintdev 5y agoNow I wish we had HyperChem, HyperCalculus, HyperBio, HyperEverything versions. Love it. Thanks for sharing OP.
- tmabraham 5y agoThey have some of that already: http://hyperphysics.phy-astr.gsu.edu/hbase/Chemical/chemcon.html#c1 http://hyperphysics.phy-astr.gsu.edu/hbase/Chemical/chemcon.... http://hyperphysics.phy-astr.gsu.edu/hbase/Biology/biocon.html#heacon http://hyperphysics.phy-astr.gsu.edu/hbase/Biology/biocon.ht...
- howling 5y agohttps://chemguide.co.uk https://chemguide.co.uk is great for A-level chemistry.
- mhh__ 5y agoThe Libre textbooks are pretty good
- fuadnafiz98 5y agoIs there any way to design the website. I am happy to do that :)
- 4gotunameagain 5y agoThere is no need to redesign it, it's like Lada. Perfect from the beginning.
- oytis 5y agoWhy? It's fast, responsive, easy to navigate and doesn't consume a lot of resources. Looks like a good design.
- tmabraham 5y agoThis is bringing back memories of my college physics class studying! Great website with simple bite-sized explanations of key topics in physics... Also, they have for other fields too: http://hyperphysics.phy-astr.gsu.edu/hbase/chemical/chemcon.html http://hyperphysics.phy-astr.gsu.edu/hbase/chemical/chemcon.... http://hyperphysics.phy-astr.gsu.edu/hbase/geophys/geophys.html http://hyperphysics.phy-astr.gsu.edu/hbase/geophys/geophys.h... http://hyperphysics.phy-astr.gsu.edu/hbase/biology/biocon.html http://hyperphysics.phy-astr.gsu.edu/hbase/biology/biocon.ht...
- jackhalford 5y agoFunny, I've been using the same sort of format for my own notes on physics [1]. Although in my graph there is no semantic meaning between graph nodes, maybe I should add that. 1: https://0x5.be/physics-notes/index.html https://0x5.be/physics-notes/index.html
- Telemakhos 5y agoI really like that, especially the SVG diagrams. Is this exported from some flavor of TeX?
- jackhalford 5y agoThe page source is markdown, compiled to html with pandoc using mathjax. There's some extra pandoc filtering magic to create hoverable equations. The svg graphs are autogenerated from markdown links inside of the pages sources.
- prpl 5y agoTIL about lua filters in pandoc 2+. I saw that there's a diagram/graphvix thing in pandoc too - is pandoc doing the svg graphs, or something else doing the autogeneration?
- jackhalford 5y agoThe svg graphs are just generated from extracting markdown links. Right now it's a bash script that writes dot code to a file, and then the dot is compiled to svg... I really need to switch that bash script to jinja or anything a little more serious.
- buraksarica 5y agoIs there a name for this type of presentation? A specific type of graph or etc?
- pbhjpbhj 5y agoOne second on the site and one can tell it started on HyperCard; for some reason the name didn't flag that for me. Seriously old school.
- mangecoeur 5y agoI loved this site in my student days, but i really wish they'd change the background color! Just make it #ffffff and it looks loads better!
- joelbondurant 5y agoDirect linking to alleged Science is a sin, only the USA Fact-Check Algorithm may confer links to ordained Science ministry.
- oytis 5y agoI wanted to praise this page for the absence of tracking among the other "modern" things, but then it turns out it makes some requests to nerdydata.com. A bit disappointed, but still a great resource.
- dghughes 5y agoI thought everyone knew of this site by now. The design is simple, clear, not wordy. It's a perfect site I've used it when I studied electronics and IT.
- ultra_nick 5y agoI love this style of note taking. My friends and I are trying to build a modern automatically backlinked note database. https://www.conceptionary.app/ https://www.conceptionary.app/
- rob_c 5y agoGot me through my UG studies, great resource, glad to see it's still up and running
- saeranv 5y agoThis is one of those goldmines, like engineeringtoolbox.com that I refer to all the time.
