As wikipedia says, "In an effort to avoid naming everything after Euler, some discoveries and theorems are attributed to the first person to have proved them after Euler."
-
Those were some of the most intuitive graphics I've seen when explaining Lagrange points. Well done, Scott!
-
Indian here. Came after our space agency ISRO launched a Sun probe this morning named Aditya-L1 which will stay at Lagrange 1 point.
-
For a non-science person like myself, these graphics were super helpful to better understand this concept! Just witnessed the launch this morning so I had to look for more information to further clarify L2. Thank you!
-
I'm a physics student and I've done the math. But those graphics were really next level. Thanks, Scott!
-
It always blows me away what math people were able to work out centuries ago. So much of where we are today and what we are able to accomplish is based on hundreds and even thousands of years of technology and mathematical understanding.
-
Finally, an explanation that is clear, concise, and visually communicative for us lay people. Thanks so much!
-
Scott, one of your best ever presentations with very intuitive graphics, your impeccable narration balanced between detailed but layman accessible, and kept ever-entertaining with your boundless enthusiasm! Perfectly timed preparing us for the arrival of JWSS!
-
La Grange means "barn" in France. Quite poetic really, to place your satellites in a nice safe barn in space. 👍😎
-
That 3d model representation was great!
-
Lagrange Points are incredibly complex concepts. Thank you Scott for helping me understand them a little bit more.
-
I'm pleased the youtube algorithm thinks I'm smart enough to appreciate this video
-
Lagrange points getting a scott explanation is pretty awesome
-
"But adding a third body just leads to chaos." I love how that statement is both technically and colloquially accurate.
-
Brilliantly and clearly explained, and very interesting to watch. Thanks for finally managing to make this, Scott! The rotating potential well graphics were a complete revelation moment for me.
-
Just watched for a second time; now I really get it thanks to Scott’s well paced authoritative narrative and great graphics. Thanks, and long live JWST!
-
Why is euler everywhere??? okay I'm convinced that euler's a time travelling math wizard
-
First heard of L-points in the '90s game "I-War" where they were used as start and end points for interstellar jumps but I never quite "got" why all of them existed. So thanks for this Mr Manly, you've dissipated a bit of twenty-odd year old incomprehension.
-
The contour plot max this instantly make sense. Thanks for the intuitive understanding Scott!
-
None of the other videos about Lagrange points make any sense … just guys retelling what they heard without understanding anything. I think you understand this stuff and explained it well. Thank you.
