Step 4: Add on “Blue Whale”
And I can also recommend the thread from @SciByDegrees that started me down this road

A thread which kicks-off a debate about Desert Island Graphs and the merits (various) of the BEPN Diagram

Which in turn led to me learning about the TriLinear Chart of the #Nuclides

#Physics #Particles

And this excellent explanation of how the #HertzsprungRussell diagram originated

HT @A_Weatherall

And this on the Valley of Stability

#Physics #Particles #Nuclides

Again, HT @A_Weatherall

And this slide deck for Teaching the #HertzsprungRussell diagram

HT @BernardRand

Let’s see if we can build a lesson plan out of this thread - using the Unroll instruction on @threadreaderapp

#Physics #Cosmology #Stars #Astronomy #HertzsprungRussell #Particles #Nuclides

with thanks to @A_Weatherall @SciByDegrees @BernardRand @emc2andallthat @andrewcnorman
