Did you know undergrads at Oxford in 1335 were solving homework problems about objects moving with constant acceleration? This blew my mind.

As I explained yesterday, medieval scientists were deeply confused about the connection between force and velocity: it took Newton to realize force is proportional to 𝑎𝑐𝑐𝑒𝑙𝑒𝑟𝑎𝑡𝑖𝑜𝑛. But in the early 1300s, a group of researchers called the Oxford Calculators made huge progress in understanding objects that move with changing velocity.

They discovered something called the Mean Speed Theorem: an object moving at constant acceleration over some period of time goes just as far as if it were moving uniformly with the velocity it had at the middle instant of its motion!

That's really cool. But it gets better. They gave homework problems called 'sophisms' to the students of Merton College at Oxford. And in 1335, one of them named William Heytesbury wrote a book called 𝑅𝑢𝑙𝑒𝑠 𝑓𝑜𝑟 𝑆𝑜𝑙𝑣𝑖𝑛𝑔 𝑆𝑜𝑝ℎ𝑖𝑠𝑚𝑠, which gives us a look at what these problems were like. Some of them required students to know the Mean Speed Theorem!

Later in the 1300s, Nicolas Oresmus in Paris gave a picture proof of the Mean Speed Theorem. For example, he pointed out that the triangle ACG below has the same area as the rectangle ACFD.

Why did it take so long for Galileo to rediscover this stuff? How did the knowledge of the Oxford Calculators get lost?

btw, the way the commodore 64 mastodon client (which is called "MOStodon", very clever...) works is you host a server on another computer using a python script and connect to the computer like you would with a BBS, which is pretty neat. it would be cool if someone made a web proxy that worked similarly

I honestly couldn’t tell if this was a joke but it did make me want to bike past doing a loud monologue

daniellecoffyn • 15h My poem won a Pushcart Prize alongside Diane Seuss and Joyce Carol Oats IF ADAM PICKED THE APPLE by DANIELLE COFFYN from SOKTH MENIDIAN REVIEW There would be a parade, a celebration, a holiday to commemorate the day he sought enlightenment. We would not speak of temptation by the devil, rather, we would laud Adam's curiosity, his desire for adventure and knowing-We would feast on apple-inspired fare: tortes, chutneys, pancakes, pies. There would be plays and songs reenacting his courage. But it was Eve who grew bored, weary of her captivity in Eden. And a woman's desire for freedom is rarely a cause for celebration.

Not one conservative in a thousand understands this.
Photo farmer standing in front of a field of corn. Text: There was a farmer who grew excellent quality corn. Every year he won the award for the best grown corn. One year a newspaper reporter interviewed him and learned something interesting about how he grew it. The reporter discovered that the farmer shared his seed corn with his neighbors. "How can you afford to share your best seed corn with your neighbors when they are entering corn in competition with yours each year?" the reporter asked. "Why sir," said the farmer, "Didn't you know? The wind picks up pollen from the ripening corn and swirls it from field to field. If my neighbors grow inferior corn, cross-pollination will steadily degrade the quality of my corn. If I am to grow good corn, I must help my neighbors grow good corn." So is with our lives... Those who want to live meaningfully and well must help enrich the lives of others, for the value of a life is measured by the lives it touches. And those who choose to be happy must help others find happiness, for the welfare of each is bound up with the welfare of all.

Very often drivers yell at me something like "go ride a bike way". It's often on a road where there is no bike way nearby and there is no legal restriction for me riding the road.
But when there is a restriction for motorized vehicles, nobody cares. Like literally every day on this road.
That's what #cycling in #Prague looks like.

The media just conceded on #CBC their relentless push to expel Justin Trudeau has failed. Can we now get back to the business of the whole foreign interference thing and how the leader of the opposition won’t get a security clearance while he has foreign agents in his cabinet*?
