sizes show the steel beam dimension for a steel i beam where S can be selected... | {"url":"http://www.all-concrete-cement.com/steel-beam-sizing.html","timestamp":"2014-04-19T15:14:59Z","content_type":null,"content_length":"13368","record_id":"<urn:uuid:21799792-d29c-4feb-bb32-642a4e312339>","cc-path":"CC-MAIN-2014-15/segments/1397609537271.8/warc/CC-MAIN-20140416005217-00615-ip-10-147-4-33.ec2.intern... |

The single bit is used only to represent a tinny piece of information. To get effective numbers, the computer combines the bits. The first combination of bits consists of grouping four consecutive

I'm confused
I am not familiar with these equations, but I try to give some opinions for discussion.
The problem is that there will be an unexpected term, i.e. exp(i*q), if the B(m)B(m+1) are transformed in K-space.
As I learned, B(m)B(m+1) denotes the transition process between state m and state m+1.

Re: Can U solve this?
In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
