comment QM without complex numbers
Searchability is also a major plus! Sometimes rather extraordinary Feynman tidbits can be hidden away as a asides in an overall text that does not seem relevant to the topic. There are even rare cases where the audio has insights not in the text, though the online version of course does not help there.

comment QM without complex numbers
Hi Rod, wow, thanks, you are exactly right about the typo! Thanks also for that link. I love that Caltech has made a clean electronic copy with inline formulas! Feynman never, ever lost track of the fact that physics is fundamentally about finding simplicity within seeming complexity, not the other way around, and his Lectures capture that theme beautifully.

comment What is the safest distance to create a star?
It's going to depend on a lot of issues, including time span, since over enough time even distant stars can rumble by way too close. We live in a region sparse enough to make a few billion years of safety plausible.

You know, the more I looked at this, the more I realized it was more complex than I first thought. It requires setting several parameters and making some assumptions. I'd be curious to see how folks analyze it.

Sohaib, you need to be more specific, even for an opinion. The most important "recent" event for magnetism itself was Ironside's conversion of Maxwell's equations into their current form, which pretty much closed the book on how magnetism works. Given that, is your question about new magnetic materials, or new designs, or what? You might even want to consider asking over at Chemistry SE if your real question is about interesting events in magnetic materials.
