While figures like Martin Luther King Jr. & Rosa Parks are well-known, there were countless local leaders who galvanized their communities. People like Fannie Lou Hamer (MS), Ella Baker (VA), and Amelia Boynton (Selma AL), who emphasized the importance of grassroots organizing, were pivotal to the success of the Civil Rights Movement in America.

Born in 1910, Dorothy Crowfoot Hodgkin perfected X-ray crystallography, a type of imaging using X-rays to determine a molecule’s three-dimensional structure.
She determined the structures of insulin, penicillin & vitamin B12, leading to tremendous advances in medicine.
Hodgkin was awarded a Nobel Prize in Chemistry in 1964. She also advocated for world peace, campaigning against both the Vietnam War & nuclear weapons. https://www.nobelprize.org/womenwhochangedscience/stories/dorothy-hodgkin #HistoryRemix #science #history
Beaches are places of intertidal liminality. Transient, impermanent and ever changing. To be the first person to walk on the sands as the tide retreats, is to find the world remade.
@SDF May you donate both to https://icm.museum ??

An example of how digging deeper can change your understanding of a whole story from the past. I had thought that the 414s, hackers busted in 1983, first met in the scouts, in fact they met on a BBS "online" & then joined the scouts together.

A family stands before a 1,341-year-old Sequoia tree known as "Mark Twain," which was cut down in 1892 in the Pacific Northwest. The tree, towering at 331 feet (100 meters) in height, was brought down by a pair of men who worked for 13 days to saw it.

U.S. forces sent to Britain in 1943 expected to export racial segregation. When white MPs insisted that a local pub segregate, the owner replied he would. When MPs returned next day, they were met with “Blacks Only” signs & British barmaids telling white soldiers to wait their turn when they assumed they would be served before black soldiers. This set the stage for the epic Battle of Bamber Bridge.

amazing that this jew with 1.300 subs gets into my recommendations, telling me exactly what youtube wants an armed, single white man to believe.
Belly laughed that his point is just “americans are suckers! they’re so generous!”, and the idea that’s supposed to make me nod along in proud patriotism

There's a nice round number: There are now 1000 documents in the Irish Left Archive!
That includes newspapers, magazines, posters, leaflets and pamphlets from hundreds of left organisations in Ireland's history.
Physicist Lise Meitner’s brilliance led to the discovery of nuclear fission. But her long time collaborator Otto Hahn, was awarded the Nobel Prize in Chemistry without her in 1944, even though she had given the first theoretical explanation.
Albert Einstein called Meitner “our Marie Curie." She also adamantly refused to work on the atomic bomb during WWII. https://whyy.org/articles/lise-meitner-the-forgotten-woman-of-nuclear-physics-who-deserved-a-nobel-prize/ #science #history
X marks the unknown in algebra – but X’s origins are a math mystery.
The Conversation explores "a few different explanations that math enthusiasts have put forward."
AWAITING DESTRUCTION--Old Pacific Electric cars are piled up at a junkyard on Terminal Island, in CA 1956. Parts Terminal Island w/in LA Port and Long Beach Port--used now for parking containers.
In the interwar years and mid-20th C. many US cities made fateful decisions for our climate in abandoning electric street railways for freeways & autos, none more than Los Angeles.

“For the horrors of the American Negro’s life,” wrote James Baldwin in 1962, “there has been almost no language.” The history is clear. America gave Black Americans nothing. What freedom we have was earned through blood, toil, grit, perseverance, & courage. After the deadliest insurrection in American history, Black-New Yorkers rebuilt their lives, shaped their destinies & contributed to the ongoing freedom struggle.

My first smartphone was the Nokia 9210i Communicator. This was also the first phone that had the Opera browser. The phone I used was a prototype of that phone, given to me by Nokia.
The phone had a full keyboard, which was actually pretty good. It had a wealth of useful Psion applications.
I kept using this phone for years. It really was that good.
Before that I had other mobile phones from #Ericsson and #Nokia.
What was your first smartphone?
Eight years ago today, I spent the afternoon going to a lot of weddings at Davidson County Courthouse in #MetroNashville, #Tennessee, and then sped downtown to celebrate #MarriageEquality with music and song. Wasn’t #NashvilleInHarmony wonderful? What a glorious day that was! Thanks to heroes #EdieWindsor (#RIP) and Jim #Obergefell. 🙏🙏🏳️🌈🎊#Nashville #LGBTQIA #history #memories #saygay #pride #pridemonth #activism #law #justice #StayVigilant #RememberRoe
