And I'm in it !!

Don't let that put you off ... the rest of it is pretty good.

What hashtags should I use?

Every polynomial with real coefficients factors into linear and quadratic terms.

How much machinery is needed to show this?

If it crosses the X-axis then it has a linear term.

If it doesn't cross the X-axis then it is of even degree, and the roots come in complex conjugate pairs.

What the minimum needed to see this?

Some time ago ... (A month!) ... there was a thread on Twitter that I think should be shared here. I've been trying to extract and post it semi-automatically, but Twitter just makes it damn near impossible.

So I'm copying it "by hand"

Here's a chart of the full conversation:

Here's the head of the conversation:

Some fun math "switcheroos":
A% of B = B% of A
log_b(a) = 1/log_a(b)
Sin(A) = Cos(B) in right triangle

Do you have any others in this style? Would love to add more to this list.

#OTD in 1897, the first International Congress of Mathematicians was held in Zürich, Switzerland. The congress even included four women!

That makes today a great time to point out that we have film-based lesson plans for math classes. — Yes, you can teach math with film!

Get our free, classroom-ready lesson plans to teach math with films like Hidden Figures (the math of space travel), Like Stars on Earth (the math determining your grade), Whale Rider (Fermi problems) and more.

Get students of all genders excited about math. Learn more: https://journeysinfilm.org/articles/teach-math-with-film-for-math-and-stats-month/

Like all our resources, our math lessons are free for everyone.

Have you ever seen a circular slide rule? https://cacm.acm.org/blogs/blog-cacm/279914-rare-circular-slide-rules/fulltext #mathematics #mathchat

Thus, for EVERY prime p > 3, either p-1 or p+1 must be divisible by 6.
How often? ALL THE TIME.

That was fun! Please share how you thought about it. And check out January Calendar of problems for more #ProblemSolving

Q) What do you get when you have a functioning #NHS in one hand & #ToryCriminalsUnfitToGovern in the other?

A) An #NHSCrisis, impoverished & smaller #NHSstaff on the brink & untold patient suffering.

Simples.

#MTBoS on Mathstodon. We should organize a chat, sort of like the original #mathchat that helped jump start the #MTBoS community in the olden days of yore on Twitter.
