It has been a while since I have been online but I would just like to share this very impressive interactive map detailing the spread and number of cases of #coronavirus . I found it most interesting.
Please #StaySafe and #StayHome during these times.

Bagel/doughnut modeling in @geogebra#AugmentedReality! 😋 Plus, a 360-deg tour inside a #torus! How can we change eq(s) to create a larger hole in middle? How can we make circular cross sec’s (from vertical plane slices) bigger or smaller? @AppleEDU#MTBoS#ITeachMath#ARKit
Last week, my Year 8 class @GuildfordHigh constructed these beautiful geometric patterns, following video tutorials by @dearingwang.
Emily’s colourful pentagram is particularly spectacular.

Here's a good way to visualize factorial growth: imagine a cell that divides in 2, each child cell will then divide in 3, each grandchild cell will divide in 4 and and so on.
Today’s #GoogleDoodle features the disembodied hand of philosopher Gottfried Wilhelm Leibniz (b. #OTD 1646), who published an article on binary arithmetic (Explication de l'Arithmétique Binaire) in 1703 & was an integral figure in the creation of #calculus. #histSTM#math#badpun

PAPER
"Von Neumann’s First Computer Program" by Donald Knuth
In 1945 Von Neumann wrote a sorting algorithm for the EDVAC (Electronic Discrete Variable Automatic Computer)
This sorting algorithm later became known as Merge sort

Introduced into India c.1300s, astrolabes were used to track the movements of stars across the sky, tell time and navigate. See an astrolabe on display in our free exhibition #IlluminatingIndia. Closes today! https://t.co/GDqdUhYyd0
