Information may sound abstract to most physicists, except its confusing application to entropy in thermostatistics. Skipping the technical details, an effective information processor should contain two key functions: computation and storage. In this presentation, Professor Lin would start with the recent breakthrough in magnetic random access memory (MRAM), explaining how spin current opens up brand new opportunity for the next-generation MRAM. Then, he would switch gear to discuss how our brains, presumably effective information processors, handle massive information from everyday life. Comparing similarities and differences between computers and our brains, it provides intriguing insights for building computers fed on information training and understanding our brains as well.
