20 Years of SLA
Tomorrow morning, Science Leadership Academy opens its doors for the 20th time. To say that it has been a heck of a run is purely an understatement. In that time, we've worked with thousands of kids, and we've done all that we can to show the world that an inquiry driven, project based, caring school really can make a difference in the lives of the students and the educators who inhabit it.

This is very much a half-baked idea right now...
A huge tension we have in public schools...
For the institution, "all" is a higher goal than "each," but for parents, "each" is more important than "all."

Joel Embiid makes $55.2 million - 35.7% of their payroll. He repesents 3% of the minutes on the floor this year. (48 * # of games * 5))
Paul George makes $51.6 million for 33.4% of the payroll. He represents 2% of their minutes.
That's 69.1% of #Sixers payroll playing 5% of the total minutes.

If you want to know why Hegseth is panicking about reminders that there is accountably for giving or carrying out illegal orders, it’s likely because he knows he has given illegal orders to murder people.

I hate to say this, but if Joel Embiid cannot play 40 games a year, the Sixers need to stretch and waive him after this season.
They cannot spend $60-$70 million a year for the next three years for a part-time player.

President Trump frequently demonstrates his disdain for journalists. He expresses his admiration for authoritarians almost as often. Tuesday showed how intertwined those two instincts really are.

Donald Trump could have just kept his mouth shut about Jamal Khashoggi.
But to smear a dead journalist, while sitting with the person accused of orchestrating his murder is just vile.
Every time this administration hits rock bottom, a trap door seems to open.
Cretin behavior.

Increase in productivity since 1979: 87%
Increase in hourly pay since 1979: 32%
Just so happens that ~25% of workers were unionized in 1979. Today? 10%.
As unions declined, the super-rich have taken a larger share of wealth generated by labor. We must build back union power.
