We are working on simple machine language in computer science for data manipulation. All the other problems I have gotten through but this last one. Here is the problem: "Write a short program in machine language to perform requested activity. Assume the program is placed in memory starting at address 00- -If the value stored in memory location 44 is 00, then place the value 01 in memory location 46; otherwise, put the value FF in memory location 46." Lots of questions inside DX Working with very basic Op-code and Operand setups. [more inside]
In the From Eternity to Here episode of the Science Talk podcast, Sean Carroll says that without entropy there could be no memory. Could you provide an explanation of why that is to somebody who's very much a layperson when it comes to thermodynamics? [more inside]
Looking for fiction books, tv shows, movies, etc, that have something interesting to say about memory-- e.g., why we remember some things but forget others, the quality of memories, anything like that. [more inside]
I'm trying to remember the name of a sci-fi book. I read it like 10 years ago, so my memory of it's a bit fuzzy. One of the major topics was something about the religion of science. I remember a guy who was able to trick people, a traveling salesman of sorts, who sold someone a machine that turned lead into gold. The machine actually worked, but would stop working after he got away with his money. I don't *think* I'm imagining this book, but who knows...
Scientists out there, what are the best physical constants or material properties to have memorized for back-of-the-envelope calculations? [more inside]
Is there a mathematical formula relating time and memory? [more inside]
memory-filter: Why or how does the body seem to remember learned physical action sequences before you can mentally recall what they are? [more inside]
I am looking for a quote from an article. The quote discussed how the current state of the art in technology usually became the metaphor for how we understand and describe the universe. The article is probably 5-6 years old, but was posted on the web (I probably accessed it through Arts and Letters Daily). [more inside]
fff asked a really good question about how children think. Many responders wrote that they have no memories from their childhoods. This freaks me out. I remember my childhood more vividly than my college years. I have a childhood friend who also has no memories from when she was a kid, which is really odd, because I remember all sorts of things we did together. Have there been any studies that shed light over why some people can recall their childhoods and others can't?
