Lectures on quantum theory by Hans Bethe. At age 93 he did a series of lectures for his neighbors at the retirement community. For once you can hear from physics expert without having to decode (as much) to layman terms.

Here’s the link:
Personal and Historical Perspectives of Hans Bethe.

I haven’t done “f2l only” averages but my cube times are dropping and it’s because my cross / f2l times are dropping.

When I switched to cross on bottom / f2l on bottom of the Rubik’s cube it was like I had to translate every move as I solved. I used to do Cross on top / f2l on left.

Anyway… I practice f2l slow a lot. I’m getting better at using d (little D, bottom 2 layers) turns instead of cube rotations when possible.

My cross time is definitely getting faster but it was decent already.

I gave each f2l pair a name and though of some key things that it’s color reminds me of… this made it a lot easier to see them around the cube as I insert each other pair. Great look ahead trick and it’s also helping to lock in unconscious competence of the order of colors (like what’s left and right of what). I wrote about this on my cube site.

Anyway… just thought I’d drop a quick F2l Update.

OK, so as soon as I got  the 2 look permute last layer down I continued on to learning the rest of the PLL algorithms.

I took about 2 weeks to really know them all and now I’m still getting faster at recognition and execution. Here and there I mess up and have to start over on the LL… it’s becoming less and less… I’m starting to feel them.  I’ve also been gaining skill with cross on bottom and F2L on bottom.

Hey speedcubers. I’m getting pretty fast at the 4 look LL algs that I’ve been learning this month. My completion times are beginning to drop below what I was averaging before I altered my method.

Also, even though I haven’t taken any averages I can tell that my cross and f2l times are going lower… I’m getting down close to 30 seconds for cross + first two layers of the rubik’s cube. That’s not fast enough… Read the rest of this entry »
