雙眼明人的感嘆: 蘋果電腦沒能完整抄襲的技術, 半世紀後還是被世人們忽視

在這一則電腦界的歷史故事當中, 我們看見資本主義及智慧財產權真正幫助到的, 並不是有創意的發明家們, 更不是廣大的社會大眾, 而是狼性的資本家們。 也看到呆伯特漫畫裡的老闆如何把自家工程師的研發成果拱手送人。 時至今日, 半個世紀前就出現的、 可以幫資訊教育開拓新視野的技術, 仍舊是鮮有機會出現在 …

發現史上增長速度最快的黑洞!不到 1 萬年增加百萬倍太陽質量

澳洲天文學家發現有史以來增長速度最快的超大質量黑洞,平均每兩天就吞噬掉一個太陽質量的物質!換句話說,這個黑洞不到 1 萬年時間就可以增加 100 萬個太陽質量;此外,由於發展極快,該黑洞每天吸收大量物質引起劇烈摩擦並釋放熱量,導致其亮度比整個銀河系還要高出數千倍。<p>說一個黑洞「明亮」聽起來很奇怪,但來 …
