#trigonometry

0 message0 participant0 message aujourd’hui

Used the laser cutter to make a holder for my class set of spirographs — for the lessons I like to do my students need to know how many teeth the gears have. They write a program that produces the same curve using turtle. (with older students we do the trig, which I just call “magic circle functions” for the grade fives)

This will make it all go much smoother!
This is 8 sets packed into one box!

Two teenagers have once again proved an ancient math rule.

From Science News: “Some people have the impression that you have to be in academia for years and years before you can actually produce some new mathematics,” says mathematician Álvaro Lozano-Robledo of the University of Connecticut in Storrs.

That is awful.

I got into legal trouble the last month of high school and happened to also be failing #trigonometry.

I found out the teacher was talking shit about me to other classes.

I confronted her about it.

She said I needed to focus on trig.

I said I didn’t need it to graduate.

I later passed trig in college and also earned a degree in #engineering.

Fuck gossipy, doubting teachers!

I’ve been working with the LEEDS 2023 Year of Culture on telling their story with data. You can look at the data microsite that I built along with the team at Open Innovations here -> data.leeds2023.co.uk.

I’ve had fun on the last proper day before Christmas making a page which lays out the striking ward motifs created during The Gift project in the same layout as our hex maps. I think it looks lovely!

3,700-year-old Babylonian stone tablet gets translated, changes history


They were doing trigonometry 1500 years before the Greeks.

Most historians have credited the Greeks with creating the study of triangles' sides and angles, but this tablet presents indisputable evidence that the Babylonians were using the technique 1,500 years before the Greeks ever were.

Mansfield and his team are, understandably, incredibly proud. What they discovered is that the tablet is actually an ancient trigonometry table.
