Most everyone is familiar with the difficulty of getting ketchup out of its bottle. Part of the trouble is that ketchup is a shear-thinning fluid, meaning that its viscosity decreases with an increasing rate of shear. Thus, a shear-thinning fluid flows better once it starts moving. This is why the ketchup moves much faster once it is initially disturbed. LiquiGlide, a new coating material demonstrated above, has gained a lot of popular attention in the press recently for solving the difficulty of the stuck condiments. It appears that the coating reduces the static coefficient of friction between the food and the bottle, meaning that the ketchup starts sliding down the wall even before an increase in shear stress starts the flow.

"When I was a student at Cambridge I remember an anthropology professor holding up a picture of a bone with 28 incisions carved in it. “This is often considered to be man’s first attempt at a calendar” she explained. She paused as we dutifully wrote this down. ‘My question to you is this – what man needs to mark 28 days? I would suggest to you that this is woman’s first attempt at a calendar.’
It was a moment that changed my life. In that second I stopped to question almost everything I had been taught about the past. How often had I overlooked women’s contributions?"

I’ve been rewatching The Office over the last couple weeks. So many feelings!
Also apparently rewatching isn’t a word.

JC Penney’s new ad for Father’s Day
The text reads:
“First Pals: What makes Dad so cool? He’s the swim coach, tent maker, best friend, bike fixer and hug giver—all rolled into one. Or two.” The text at the bottom reads: “Real-life dads, Todd Koch and Cooper Smith with their children Claire and Mason.”
I can’t.

Joan Trumpauer Mulholland, 1961.
Joan, a 19 year old Freedom Rider, was sentenced to two months in prison for her involvement in the integration of a Jackson, Mississippi bound train. She served more than the required two months because each addition day reduced her $200 fine by $3.
In the Fall of 1961, Joan transferred from Duke University to historically black Tougaloo Southern Christian College because she felt integration should be a two way street.
Today Joan is a retired teaching assistant living in Virginia and mother to five sons. After the 2008 election she brought her Obama pin to the grave of Medgar Evers.
Everything about this.
