OCR: well, on YouTube some things get taken off. Maybe a text description will do? Soon-to-be convict Ken Lay is boss of Enron before its implosion, and despite current bad news, gives a very upbeat presentation of the future of the company to a large assembly of his employees. Afterwards, he...

This is part of a much bigger issue, how does a one-to-many broadcaster such as a teacher/lecturer get feedback via the many-to-one channel. Many, many methods have been tried, and success is variable. In terms of passive students, who may actually harbour good questions, anonymity helps. This...

It sounds as if you're looking for the results of a controlled experiment on this. I don't know for sure, but I'm hoping folks in Educational Research have done something on this. Maybe advanced and exhaustive google searches will throw up a paper about it. While I agree with the replies, I...

Good question, and great replies. The cycles idea, and how understanding is rather a quantity with levels is something I'd totally go with. In some cases, it takes many many years. The point I in particular identify here is Feynman's implication that learning by rote is NOT part of...

Thanks Ygggdrasil. Will read. Cheers.

OK, I want to suppress my interpretation of the word "open" here. As you recall, I thought it may refer to the open start-end of a reading frame. From reading around, it appears that this is unlikely. Doolittle's 1986 book, "On URFs and ORFs" is probably an early enough reference and it...

Hi, I disagree with the point that redundancy in the genetic code leads to more diversity. If different codon strings map to the same amino-acid, the tendency will be towards uniformity of the amino-acid sequence, despite differences (or mutations even) in the nucleotide sequence. So if I was...

I also noticed there is a thread coming up as being associated with this one, called something like "Open Reading Frame?" It cannot be be added to any longer, but in it, is stated that start and end codons are associated with exons. That is incorrect and will lead to severe inference problems in...

I'd like to venture another possible explanation for the word "open" in the term ORF. Again, it's a bit of a guess, but it's useful because it highlights something not mentioned here. Start codons can also be methionines, so the frames are open at the start end, not the stop-codon end. There's...

Hi rolotomassi, Thanks for the replies! I had not thought of a non-homogeneous material/field, and it helps enormously, thanks! I can see more fully how the tensor components could be needed in that situation. Let me say that yes, intuition develops, so to speak, and with usage, as you say...

Hi, I'm trying to close in on a more intuitive way of understanding tensors. For some reason, they've always held an aura of mystique for me, may be also their similarity to the word "tense" has meant that I've never really warmed to the many defintions and explanations available. So, in many...

I think the original question overlooks what may be a valid distinction: some thing may be difficult and yet well-written.

OK, many thanks Mute, because that seems to clear it up. Yes. I now see my error in the first attempt, and how correcting it gives the answer I wanted. That was a lame answer I gave Bacle! I need to be more careful there. Having to use the absolute value when applying the logarithm is...

Oh great, some replies and interest. Thanks guys. Stephen Tashi, I'll reply to you first, first in explanatory words, and then using the general term. P_c(1) represents the probability of of the site having a "C" after the very first unit time step. The site started as "C" to begin with, so...

Yep, that's true, an annoyance rather than a bug. In relation to my derivation, it's drilling a little hole in my head, because it's only a small thing in the way of finshing it. I'm definitely scanning a lot of websites, but I'm getting no joy. Each time, I have to read over the same old...
