Elon Musk announced the Hyperloop system concept, a new method that would transport people from one side of the US to the other in just 45 minutes, a trip that normally takes almost six hours by plane. Musk describes the Hyperloop system as “a cross between a Concorde, a rail gun, and an air hockey table.” Hyperloop would a system of cross-country tubes that would consists of capsules capable of carrying six people and their luggage. Six-person capsules travel in the tubes and can reach a maximum speed of 6,500 km/h, and provide 50 times more transportation per kwh. A tube can travel from New York to Beijing in two hours, and make a round-the-world trip in just six hours.
Visualization of the Screens of Every iPhone Ever Sold Combined into Monolith Looming over Manhattan
Josh Orter of Stupid Calculations has worked out exactly how large the combined screens of every iPhone ever purchased would be. Extrapolating from Apple sales data that reports 352,292,000 sold iPhones since the product’s launch in 2007, Orter calculated that the “Kubrick-inspired monophone” would measure a staggering 5,059 feet tall and 2,846 feet across. To give you a sense of scale, Orter created an infographic placing the monophone in the middle of New York City — the massive monolith is wider than Central Park and far outstrips any skyscraper in the city. More detailed information on Orter’s calculations can be found at the Stupid Calculations website.
Scientists in Japan have developed a dream decoding system that can create a visualization of a person’s dream. Developed by researcher Yukiyasu Kamitani and his Kyoto-based team, the system uses a functional MRI to analyze brain activity and a learning algorithm to create visualizations from the brain data. While the researchers report that the system is not currently very accurate, the results are nonetheless promising and the visualizations are quite remarkable. For more on the study, see this post by the Smithsonian science blog, Surprising Science. The study was also recently featured on NPR.
