事实上，普朗克常数、万有引力常数也是类似(只是无法和某个整数关联)，稍微变动一点就会让整个宇宙不存在。
When new employees come to work at the Boeing production facility in Everett, Washington, one of their first stops is often an exhibition at the company’s Safety Experience Center. It opens on a sombre note: a memorial for famous air disasters, including the successive crashes of two 737 MAXs, in 2018 and 2019, in the Java Sea and Ethiopia. Then, gradually, the tone grows more hopeful. At Boeing, as throughout the aviation industry, disasters led to innovations. Oxygen masks and electronic anti-skid brakes were introduced in the nineteen-sixties, along with bird cannons at airports, to shoo off Canada geese and fellow-fliers. Overhead bins got latched doors that same decade, to keep luggage from toppling onto passengers’ heads. Satellite communication came along in the seventies; automated flight-management systems, capable of plotting a plane’s course, speed, and altitude, in the eighties. Radar systems got more accurate; planes grew stronger, sleeker, and more flexible. Pilots got better at skirting turbulence—or, if they couldn’t, at slowing down and “riding the bumps.”

近年来，各国大举兴建数据中心，对HBM形成饕餮需求，使芯片厂将产能转向利润高出数倍的HBM，而生产1GB HBM所消耗的晶圆产能，大约是生产1GB普通DDR5内存的3倍以上，这严重挤压了手机所用内存的供应。
