Hey, it's my birthday today. But please don't feel embarrassed that you didn't get me anything, all I want for my birthday is for you to enjoy today's new episode of #themathematicianspod. This time, Pingala, and a 10 minute beat poem... Please forgive me. #mathsky #mathshistory #poetry

Why, it's another episode of #themathematicianspod this time an interview episode with the fabulous @[email protected], author of #themathrmaticianslibrary. Listen in to hear his thoughts on writing a book about books about maths. As well as more history and philosophy. #talkingmaths #mathsky

I've just finished watching "Death by lightning" on Netflix. They appear to have missed the most interesting aspect of the #POTUS 's life, that President Garfield developed his own distinct proof of #Pythag, one without using any squares. Otherwise a good watch. #mathsky #somepresidentswereclever

My first attempt at a #DiscreteDynamicalSystem Take a number, n If (n-1) is prime then map n -> n^2 If (n-1) is composite then map n-> Aliquot sum of (n-1) Numbers 1-19 all end in a cycle. I am not sure about 20. eg. 6 -> 36 -> 13 -> 16 -> 9 -> 7 -> 6. #mathsky #recreationalmaths #mathsart

Just had a fun conversation about Primitive Pythagorean Triples with Carol Jacoby from: theartofmathematicspodcast.com Can you find a coordinate M:(a,b) such that |OM|=|MA|=k, with O:(0,0) & A:(20,20) and k an integer? You should be able to listen in at the end of March #talkingmaths #mathsky

New oeis.org/A393283 just dropped. Take a triangular array starting (0),(1,0) Now draw a ray from the tip down to the next term. Each new term is the sum of terms on or adjacent to this ray. 0 1,0 1,1,0 2,3,2,0 Try this in mod 2 for a #cellularautomata. #mathsky #sequences #recreationalmaths

New #mathspodcast episode just dropped of the #themathematicianspod, if you want to listen to #Baudhayana again, but with slightly updated mathematics, you will love the episode on #Apastamba A tower is built with one brick on top of another. Come meet India's second brick! #talkingmaths #mathsky

New sequence just dropped to the #oeis Start with the numbers [2,2,...] Then each new number is the product of the last two, written in mod n. The sequence stops when there is a repeating pair of consecutive numbers. a(n) is the length of the above sequence. oeis.org/A389543 #mathsky

New game just dropped: #Vector-bet Can you create a letter of the alphabet using a polynomial with vector coefficients? Have a play for yourself with my #GeoGebra widget: www.geogebra.org/m/hv99xfkj Featuring drag and drop vector tools and a squiggly pen! #sillymaths #mathsky

Follow up from my #alevelmaths student: If you use 2D vectors for a high order polynomial, the resulting plot is, once again, 2D - however it is highly disorganised: Here we see a Quintic Equation. #mathsky

A great observation from my #Alevelmaths student: If you create a polynomial with vector coefficients $r=a+bt+ct^2+dt^3...$ you can get higher dimensional equivalents of the polynomial. Here is a 3D quartic equation. #mathsky

New sequence just dropped to the #OEIS Have you ever wondered how many sides are needed on a k-gon such that an inscribed and circumscribed k-gon calculates the area of a unit circle with accuracy bounds up to n digits? I know I have! If you have a 12-gon will tell you π=3 oeis.org/A391013 #mathsky

My new #OEIS sequence just dropped. Least k > a(n-1) such that k + the sum of all previous terms = 0 (mod (k-2)), with a(1)=1 and a(2)=2. 1,2,3,4,... (1+2+3+4+n) Is a multiple of (n-2). ...5,... What comes next? oeis.org/A390783 #mathsky

If I say: Any square (4*4 or 8*8) may be rotated by 90 degrees, if the pieces are fully enclosed in the square. Is it possible to sort all the greens to the left and reds to the right? #playmaths #mathschat #mathsky
