Summary edit
| Description |
English: This illustrates the classic story about a farmer hoping to capture a pole vaulter running at half lightspeed in his barn as the vaulter passes through. The farmer locks the rear barn door and opens the front, realizing that the length-contracted pole will allow him to shut the door even though the pole would otherwise barely fit. The pole vaulter, who sees the barn length-contracted, figures there is no way the farmer can shut the door with both ends of the pole in the barn. Who is right? |
