If anyone is interested, the draft for my next bloggy thing is available, and I'd appreciate any comments, criticisms, and feedback. Unalloyed praise would be nice, but I don't think it deserves that.

@ColinTheMathmo Huh, I feel a bit stupid for asking, but... where can one find it? :)

@arx It's on my blog already, but you can find the post itself here:

solipsys.co.uk/new/RoundingUpT

As I say, thoughts welcome. It is the latest in a series.

@arx Usually the people who respond are regular readers, who therefore know where to find it. But if you're new to it then it's definitely not a stupid question, and you're very welcome.

Hello!

@ColinTheMathmo Yes, and I now see that it is a series, so one should really read the prior blog posts, too. :)

I love puzzles like these -- and I also think the level of difficulty is just right, at least for me: it is not at all obvious, but it's also not impossible to figure out on your own.

Will watch the blog more often. :)

@arx They really do pretty much stand alone, so you can read any in isolation.

@ColinTheMathmo I think following the links to the others helps, though. For example I was at first a bit confused about the explicit discussion on how to compute 4^(1/3), after all there are calculators ;), but then I read in the earlier post that a goal is to present an answer that can be computed *without* restoring to a calculator, so it all made sense. Also, at first I couldn't really see why Rθ=D+3, but it made sense after looking at solipsys.co.uk/new/TheOtherRop...

@arx Perhaps I should add a side-box to remind people of the reason - would that be helpful? Comments like this are useful - they help me make each post clearer.

@ColinTheMathmo It think it would have been helpful in the sense of efficiently understanding what is going on... (Maybe something like "What is this all about?" or "What do we already know?")

But, you know, given that this is more about joyfully exploring mathematics and not about getting an answer as efficiently as possible, I didn't mind at all reading into the other posts as well. :)

@arx Cool - enjoy! Let me know of any thoughts and/or feedback.

@ColinTheMathmo Thanks! And thanks for all the work you must have put in there, it is really cool and interesting!
