Introduction to lorentz transformation 🚀
- Origin: Lorentz Transformation equations were proposed by Hendrik Lorentz to explain the Michelson-Morley experiment results.
- Einstein Connection: Einstein demonstrated that these transformations could be derived from his modifications to Newton's postulates of special relativity.
- Core Idea: Measurements in one reference frame might appear differently in another moving frame. Space and time aren't absolute!
Comparing with galilean transformation
- Galilean:
Δx' = Δx(Length remains unchanged when switching frames) - Lorentz:
Δx' = γ(Δx – vΔt)(Length can change!)
- 🎈 Imagine measuring the length of a balloon in a moving car and then outside. Might seem different, right? That's the kind of weirdness we're talking about!
Space-time transformation - lorentz style!
- Position in a moving frame:
x' = γ(x – vt) - Time in a moving frame:
t' = γ(t – vx/c2)
- 🎈 If you tried measuring the time it took for a movie to play while zooming past a cinema in a spaceship, you'd get weird results!
Absolute space & time? think again!
- If two people in different moving frames measured the same distance, they'd disagree. Like arguing over pizza slice sizes at a spinning party!
- Lorentz showed time isn’t absolute either. It’s like different people watching the same movie but feeling it lasted differently!
