As humans, we have a very intuitive concept of time, and of the differences between the past, present, and future. But, as scientists Edward Feng of the University of California, Berkeley, and Gavin Crooks of the Lawrence ... | |
Ultra-Fast Quantum-Dot Information Storage March 21, 2008 | User rating: 4.7 / 5 after 95 vote(s)
| User comments: 8
The information-storage market is dominated by two main types: Flash memory, used in memory sticks and cell phones, and dynamic random access memory (DRAM), which is the main memory in a personal computer. Both types have ... | |
 'Phononic Computer' Could Process Information with Heat November 02, 2007 | User rating: 4.2 / 5 after 74 vote(s)

Most computers today use electrons to carry information, while theoretical optical computers use photons. Recently, physicists from Singapore have proposed a third type of computer: a “phononic computer,” ... | |
 Moth eyes may hold key to more efficient solar cells February 22, 2008 | User rating: 4.7 / 5 after 111 vote(s)
| User comments: 4
One of the difficulties with solar power is that solar cells are notoriously inefficient. Some of that inefficiency, says Peng Jiang, is due to the fact that silicon is reflective. Jiang, an assistant professor ... | |
