Nokia 9 PureView camera system

The Nokia 9 powered by the Qualcomm Snapdragon 845 Mobile Platform is a major achievement in computational photography. Thanks to a collaboration with HMD, Light, and Qualcomm Technologies, the Nokia 9 is the world’s first smartphone to feature a five-camera array. Every time you take a photo, the cameras collectively capture and process up to 240 megapixels of data, which is then used to create one stunning 12-megapixel photo and a corresponding 12-megapxiel depth map. This is the largest amount of photography data ever captured and processed by a Snapdragon 845 device. By combining the best parts of the data to form one image, the Nokia 9 is designed to ensure your photos feature stunning sharpness, bright colors, dynamic range(12.4 stops), and depth for realistic-looking Bokeh. The five-camera modules that make this possible are nearly the same. They contain the same Sony IMX486 image sensors, which have 1.2μm size pixels, and lenses, which have 28mm focal length with brig...

3d printing rebound resin

TripleCell platform can deliver components that are pretty close to traditional performance cushioning, thanks to the proprietary photopolymer Rebound Resin that was developed as a result of the partnership. Rebound Resin was designed in order to make resilient, springy lattice structures with, according to a Formlabs press release, “the durability, reliability, and longevity expected from an injection molded thermoplastic.” simulation The TripleCell 3D printed components deliver more lively, spring-like cushioning than you’ve ever experienced in foam, with the ability to ultimately be produced on-demand in our own facilities in Massachusetts.

Allais paradox The Allais paradox conclusively shows that when people are pressed for answers in quick time spans, they often give inconsistent answers. But that does not necessarily mean they have inconsistent preferences.  Recency bias Recency bias is the phenomenon of a person most easily remembering something that has happened recently, compared to remembering something that may have occurred a while back. Gambler's fallacy The gambler's fallacy, also known as the Monte Carlo fallacy or the fallacy of the maturity of chances, is the mistaken belief that if something happens more frequently than normal during a given period, it will happen less frequently in the future (or vice versa)

third rail issue of politics

The third rail of a nation's politics is a metaphor for any issue so controversial that it is "charged" and "untouchable" to the extent that any politician or public official who dares to broach the subject will invariably suffer politically. The metaphor comes from the high-voltage third rail in some electric railway systems. Touching a third rail can result in electrocution, so usage of the metaphor in political situations relates to the risk of "political suicide" that a person would face by associating with a certain cause, topic, or subject having a highly controversial or offensive nature. Joe Tsai said Territorial integrity and sovereignty as non-negotiable (third rail) issues wiki
