字幕依据：This video was made possible by Brilliant. Learn with Brilliant for 20% off by being one of the first 200 to sign up at brilliant.org/Wendover. The purpose of the Panama Canal is pretty easy to understand. It brings the US west coast closer to Europe, and it brings the US east coast closer to Asia. KgsxapE27NU@0:00
字幕依据：Now, the Panama Canal is not just one straight shot from ocean to ocean. That’s because the artificial lake they created, Gatun Lake, is 85 feet or 26 meters above sea level. So, cargo ships, which can weigh more than a billion pounds, need to get up those 85 feet or 26 meters and then back down again to transit from ocean to ocean. KgsxapE27NU@1:07
字幕依据：This class of ship is called NeoPanamax or New Panamax or Post Panamax depending on who you ask. Of course, there are certainly ships larger than the NeoPanamax size. The Panama Canal has a size limit of about 15,000 TEU or twenty-foot equivalent units. KgsxapE27NU@2:24
字幕依据：That’s why they spent $5.4 billion to build these bigger locks that could fit larger, 15,000 TEU ships. This would let more of the world’s shipping fleet through and these bigger ships, thanks to economies of scale, have lower cost per container which helps make the canal more attractive in comparison the its trains or Suez competition. KgsxapE27NU@5:55
字幕依据：In the middle of the 19th century, the California gold rush brought thousands of settlers to America’s west coast. But finding gold may have been easier than transporting it back east. The only hope for avoiding a grueling six month wagon journey was to travel the narrowest portion of the continent— the 48-kilometer Isthmus of Panama. uE_UuHRtXCY@0:06
字幕依据：Futile excavation efforts were buried under constant landslides. And since the diplomat had only visited the site briefly during Panama’s dry season, his workers were unprepared for torrential storms, venomous jungle fauna, and tropical diseases. uE_UuHRtXCY@1:19
字幕依据：Within days, they became an independent nation and signed a treaty to begin construction of the canal. Just over a decade after the French left, the Americans were ready to dig in— and they were determined to avoid their predecessor’s mistakes. uE_UuHRtXCY@2:24
字幕依据：Then, in the fall of 1913, the moment finally came. A telegraph signal from President Woodrow Wilson triggered a dike explosion, flooding the Culebra Cut and joining the Atlantic and Pacific Oceans. Today, nearly 14,000 vessels travel through the isthmus annually— each in under 12 hours. uE_UuHRtXCY@4:41
