2018-04-04: The Unruh Effect
- 09:27: The Rindler and inertial observers disagree on the source of the energy even if they agree on the final result.

2018-01-17: Horizon Radiation
- 00:46: And for two observers with very different, but constant speeds-- inertial observers, the vacuum itself should appear the same.
- 03:33: There's no conflict for constant speed inertial observers.

- 01:54: ... flat spacetime diagrams of inertia observers, the world lines of other inertial observers are straight, indicating constant spatial ...
- 02:03: This captures Newton's idea that inertial observers shouldn't accelerate relative to other inertial observers.
- 03:43: However, global inertial observers do.

2015-07-22: SPECIAL ANNOUNCEMENT + Flat Spacetime Geometry Comments
- 02:48: Inertial observers will see each other dynamically, moving with a constant three-dimensional velocity.
- 02:54: But does that mean that inertial observers are really moving with a constant three-dimensional velocity?
- 03:22: Those are the guys that, it turns out, corresponds to inertial observers in Newtonian physics.
- 04:32: ... diagrams that I drew in the last episode were from the point of view of inertial observers-- Blue Gabe, Red Gabe, the ...
- 05:01: Imagine a family of inertial observers, all of whom are moving with different speeds relative to each other.
- 05:06: That accelerating car, at any given moment, from its point of view, is always stationary instantaneously relative to one of those inertial observers.
- 04:32: ... diagrams that I drew in the last episode were from the point of view of inertial observers-- Blue Gabe, Red Gabe, the ...

2015-07-15: Can You Trust Your Eyes in Spacetime?
- 06:49: Inertial observers have geodesic world lines and noninertial ones don't.
