Grandmasters told me that learning openings which give a fraction of a pawn advantage didn’t make sense until kids could win with a queen advantage. Also, no matter their eventual playing style, kids should begin with attacks.

Solving chess positions eg from Reinfeld. When I taught chess, they began with one white wins, one black wins, from a piece of paper identifying starting position. They set them up and solved them. Or if they set up position from book, they say pawns on a4, b4, and c6 while setting them up.

It was amazing!!!

8% sounds high, even accounting for shoppers nearby and, at my local one, drivers who won’t be counted, but honked and waved like crazy. 10+% brought their own signs and sometimes the whole family.

Should drivers, bus riders, etc who wave and honk be counted?

8% is like the old “Do you watch PBS?”

Teacher here. I always say 40”/1 meter, because my goal is to communicate. Except in physics where I give one problem per semester in American units to assure that no one objects to using metric from then on.

They will pay me 14x the current price to buy their product. 100% of the price drop was used to get it to free.

Defunding trips to Trump golf courses, require Trump to stay at work?

Yes, the MAGA people are obviously very optimistic about how robust our society is, because they think it can weather all of these insults without destroying our quality of life.

California representatives are 17% R in a state that voted 34% Trump, 9 of the 52 representatives. Proportional representation means Rs would have 18ish seats.

Thanks!

Charts 27 and 28 compare roof mounted vs ground PVs. All the impacts of roof mounted are larger, except for land use (and carcinogenic effects?)

Questions:
Capacity factor US solar at 35.017,-117.333 (Mojave Generating Station) is only 18%? Europe averages 12.4%!

Global average is 52/53 (ground-/roof-mounted), so more than in EU?

Thanks!

This is European central estimate across a wide range of insolation??? German life cycle GHG emissions are double those in Spain?

Why would ground and roof PVs have the same central estimate given that PVs on the ground generate 50% more electricity?

Is this explained in their report?

Most recent WG3 (p 632) cites studies: 9-250 gCO2/kWh, 18-60 g, and central estimates of 80 g, 50 g, and 20 g.
