科学技术是效率的强大动力。１９世纪中叶，出现了热力学、电磁学两门学科，到了１９世纪末，造出了发电机和内燃机。进入２０世纪，兴起了以电力和内燃机为标志的技术革命。技术革命极大地提高了效率，但却不能推动公平，甚而出现了反公平的势力，导致世界更不公平，最后... Science and technology are powerful forces for efficiency. In the middle of the 19th century, there were two disciplines of thermodynamics and electromagnetism. By the end of the 19th century, generators and internal combustion engines were created. In the 20th century, a technological revolution was marked by the use of electricity and internal combustion engines. The technological revolution has greatly improved efficiency, but it has failed to promote fairness. Even the anti-fair forces have emerged, leading to a more unfair world. Finally...
