Guest, did you like the last podcast notification?? Well here's the second one, and for the third podcast! Yep. This Thursday 8-8-24 at 7pm Central
Go here to check out his podcast thread for info on topics and links!Go into the FoH discord and find the Happy Time Fun Hour channel and give it a listen!
I have always wondered how they can know what other stars/planets are made of. The color spectrum thing was really cool
Yeah just to expand on what I said earlier.
I never knew that electrons responded that way to light and would change orbits by disappearing and reappearing. That is the kind of stuff that gets the imagination working in over drive and should be taught in every class room. Amazing information and I've never heard it before. Kind of blew my mind a little.
I've always known about lights signature in a general sense. That they could look at the light and tell what was in the atmosphere and such but never understood the specifics of how it worked. The demonstration with hydrogen and salt was amazing. Showing the different signatures for more complex elements and the signatures of galaxies was very well done.
I'm a sucker for the history part of the show as well. I really enjoy the little tidbits of history and how they portray them. Especially given shout outs to the very important people that jump started our knowledge but are lesser known. Even the relationships and tidbits portrayed by well known people like Newton are all interesting and I've learned a ton.
Lots of great information and the more the episodes ramp up the more I'm enjoying them. This last episode really stands out for me though. Very well done.

This was definitely the episode that I learned the most from so far. I never heard such a simple explanation of how we can tell the composition of shit so far away. Also, Isaac Newton was a goddamn badass. In comparison to others of the times, he was an expert in everything.

The history was new to me (Chinese guy/Iraqi guy/Fraunhofer), but absorption lines I learned in college / quantum mechanics. Heh, my wife turned it off during the organ part ('why is this on, we already know this').
Since D3 is doing maintenance, I finished the episode off this morning, and the rest really was all recap of college level quantum mechanics. Still, the visualizations were fun and why I tune in.

Ha. I'm just saying this isn't all exciting and new info for everyone. But I completely understand that this show wasn't made for me.

Unbelievably, I actually took organic chem, calc, and trigonometric equations as electives in college. Pretty retarded of me.

The thing that I thought was weird was that he explained that electrons orbit until they change shell.
I didn't think that's how they work. I thought they exist as a field of possibility, they don't actually "orbit" shit. They go from point A to point C, but they do not pass through area B in order to do so. So even within their own shell, they're magical little things. Which is a different model. On the show it's like they're mini solar systems and you can draw some parallels to gravity. Even though he says, "This is not gravity at all", that IS the inference you draw from just looking at the model. On other, more in depth, lectures I've watched about them it's more like they're completely WTF.
But complete WTF might not have been exactly the desired level of detail. It's strange enough that they teleport around interacting with light. And I suppose that's the entire point (beyond the history) -- here there be magic shit.
p.s. I already knew everything

Neph was the literally the only person who came in here saying they knew it already. Everyone else has posted "I didn't know this" or "I never knew". Bunch arrogant bastards in here saying they learned shit. How dare they?
