The TI-34 is a fairly basic scientific #calculator. I’m a big fan because it’s easy to use and not overwhelming.

I was reading the manual and discovered it has two functions:

ipart(x)
fpart(x)

These return the integer and fraction parts of x.

ipart(2.34)=2
fpart(2.34)=.34

Great! So, uh.. What are these typically used for? Why include them on such a *basic* calculator? #calculators #ticalc #ti34 #matheducation #mathchat

To The Erudite In Mathematics Who Wish To Remove Infinity (∞)

An axiom of which we are all conscious: the acknowledgement of the unknown.

The symbol of Infinity is the mathematical constant that, through its own logic and reason, grants us the ability to formulate useful formulae. It demarcates a value that is unknown, yet undeniably present.

Someone has pointed out, quite rightly, that I really should tag @standupmaths when I mention a video that he has made.

I'm not sure appearing in a video counts as a connection for an Erdős number, much as people might hope it might.

So ... the monostable (or self-righting) tetrahedron:

A new video from Matt Parker:

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?

I've been thinking about this for ages, but never had the time to craft the words around it.

People keep saying that "Maths should be fun" ... and I push back with "It should be engaging ... 'fun' is a different thing.

So @rakhichawla has posted pretty much exactly this, but better than I ever could.

I'm copying it here with permission.

Please read this, then as it says at the end ... let's have a deeper conversation about this ...

(PS: I'd love this to get boosted to get outside my bubble ... you're all amazing, but there will be other opinions, and other thoughts that could be helpful or valuable)

Fermat conjectured that for \(n\) a non-negative integer, all numbers of the form \(2^{2^n}+1\) are prime.

Was there ever a worse conjecture in maths than that?

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:

#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 of 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.

Two lines, 𝓁 and 𝓂, both have positive slope.
The angle 𝓂 makes with the x-axis is twice the angle 𝓁 makes.
The slope of 𝓂 is nine times the slope of 𝓁.
Find the slopes of the two lines.

@samjshah Fabulous!

Once they've joined it would be useful to have a consistent hashtag. Some that have been used already include:

#MathChat #MathsChat #MTBoS #MathEducation #MathEd #education #teachers

It will be great to get the math teaching community here and get some cross-fertilisation.

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.
