@pejorgens This is a grand memento for a professional pause in career! Thanks for the comment but I got the idea from the math faculty at San Lorenzo High - especially Phil Tucher, Carlos Cabana, Ruth Tsu, Susa Baskin and Hannah Whitzman

@howie_hua What do you mean by WAS?

[Oakland Education Association @OaklandEA]

OUSD has failed to come to the table in good faith. Educators will be on the picket line tomorrow, on strike for our students & for Oakland schools. Join us on the picket line. We will continue to negotiate in good faith & hope the district does the same. #Unite4OaklandStudents

We can right this ship, but at this moment in time, voting Democrat is the ONLY way to do it. And, people who don't like to vote? Do it anyway. We need you.

@N_Marie_W what do you mean- USED TO?

I love math interviews but I may have lost it last night at dinner. 
Me: Hey, Google, what's 1/2 plus 1/2?
Google: 1 divided by 2 plus 1 divided by 2 is 1.
Me (probing for more): Hey, Google, what's 1/2 plus 1/3?
Google: 1 divided by 2 plus 1 divided by 3 is approximately 0.8333.

@howie_hua The plan is to first find 22-9, then add .5
22-10 =12
so 22-9 = 13
so 22-8.5 is .5 more =13.5

Judge Ketanji Brown Jackson has earned this moment in history, she is worthy, she is a truly great American.

@scmaestra For me it was teaching seventh grade. It’s divine intervention that allowed both my son and I to survive that year. LOL

Marilyn you rock!

[Marilyn Burns @mburnsmath]

Whoa! I had no idea! This has really made my day . . . and more. Thanks, @Simon_Gregg, for letting me know.

In case you missed it, Mitch McConnell said the quiet part out loud last night: “African-American voters are voting in just as high a percentage as Americans.”

Make sure everyone sees this.

Wasn’t ready for this today—today we lost a titan, an icon. She was a writer who made us feel seen all the way down to our bones. When I say rest in power, it’s with the knowledge of all the power she’s given to the rest of us. Keep empowering, empress. 💔🙏🏿

If we weren't required to get those vaccines before we were allowed in kindergarten, millions of us wouldn't be here.

[Berkeleyside @berkeleyside]

"We're not like a restaurant where we can just not let you in if you refuse to get vaccinated," Alper said. "McDonald's has no obligation to serve every resident in Berkeley, we have an obligation to educate Berkeley students."
