Science Journey (
Summary[]
While sailing in a replica of a Viking longship, Senku explains that Viking sailors reached America 500 years before Columbus. The other crewmates question how the Vikings were able to navigate when the sun was unavailable. Senku posits that the Vikings used a stone to track the sun’s position that seemed magical. Ryusui reiterates the difficulty of their current route, but Senku is confident that their GPS technology will see them through. Gen questions how GPS will work in their situation, and Senku responds that they will coordinate with Ruri in Japan.
Back in Japan, the Kingdom of Science has built a sundial and numerous hourglasses. Ruri explains to Mirai that these instruments are used to provide the time in Japan to the crew via short-wave radio, which Senku can count accurately. The less scientifically-minded crewmembers are confused about how the time in Japan helps them determine their bearings, and Ryusui tells them that the time provides longitude and the sun’s position gives them latitude. The crew marvels at their analog GPS, and Senku proclaims that as long as the weather is nice, they will always know their location.
Some time later, the Perseus is caught in the middle of a thunderstorm. Gen dryly chastises Senku for tempting fate, and notes that for all his intelligence and determination, he has no luck whatsoever. Kaseki laments that the sun won’t be seen through the clouds, forcing the crew to rely on Ryusui’s intuition. Senku is worried about the amount of time they’ll lose if the storm goes too long. Suika wishes that they had the Vikings’ sunstone, which gives Chrome an idea. He retrieves a stone from their collection, and asks Kohaku to carve it into a prism. Chrome puts the prism into a viewing device with a rocket-shaped hole and brings it to the deck. Chrome uses his device to find the sun, and Senku excitedly notes that the prism is made of calcite, a naturally transparent stone. Ryusui remembers that calcite had been discovered in the wrecks of Viking longships, and Ukyo remarks that the legend seems to be true.
The journey to America continues without issue, as the Perseus weathers more storms. The crew sees many wondrous sights, like a massive iceberg and a pod of whales. Eventually, Homura spots the shores of America, and shouts down to the crew, who are eagerly staring at the new land.
