Mathspig has become obsessed with the Galton Board since watching ELEVEN dropping discs into the peg board on STRANGER THINGS 4.
Now thanks to David Butler, University of Adelaide, you can turn your middle school class into Galton Balls. You can find 100 randomly generated instruction sheets for each human Galton Ball at David’s website. (Link above)
Ideally, you would have 3,000 students to do this activity. But the class exercise ends with something approximating a Normal Distribution or Bell Curve constructed from video tap casettes. And the NOrMal Distribution is spooky.
London yesterday. Spectators give a spontaneous standing ovation to Oxford Professor Sarah Gilbert (below), who was one of the scientists involved in developing the Astra-Zeneca vaccine and one of 100 key worker special guests on opening day. (The Age, 29 JUN, 2021)
Here are the Covid-19 Vaccination stats for the UK as of yesterday:
The UK recorded 22, 868 cases yesterday, but only 3 deaths.
The last time the UK recorded close to 23,000 cases was on 16 December 2020. That day, 613 deaths were announced. (The Age, 29 JUN 2021)
In 2019, in the UK, the total death toll was 616,014 or 1688 per day. Tragically but realistically elderly patients with multiple health issues are more likely to contract Covid and die from complications exacerbated by Covid-19 but not necessarily caused by the virus.
The death toll numbers are now encouragingly low in the UK despite the high infection rates from the highly contagious Covid Delta variant.
UPDATE:
On 9 July 2021, the UK recorded 35,707 cases and 29 Deaths. According to Worldometer stats (below), the case numbers and deaths are still rising. Too soon to celebrate even though the UK Freedom Day is only 10 days away.
Mathspig has tracked the Covid 19 Stats through the Worldometertracker and calculated the AVERAGE NO. DEATHS per day at the50, 60, 70, 80,100 , 200DAY and the 1 YEARmark ..
and now at the 500 DAY mark.
Note: Approx 1/3 of deaths around the world are due to accidents, diseases other than Covid, or suicide.
There is NO CLEAR HEIGHT ADVANTAGE for serve speed.
2. Does the serve return rate increase with height?
Here is Diego Schwartzman (L) when he defeated Alexander Zverev (R ) in the 2019 US Open.
What is Schwartzman’s Super Power?
Schwartzman, the shortest player on the circuit (see graph above), tops the service returns stats. Highest 2nd serve return rate. Third highest 1st serve return rate. See data below. So agility, speed, and reaction times are also important factors in becoming a tennis star.

Mathspig has been tracking the Covid 19 Stats through the Worldometer tracker and calculating the AVERAGE NO. DEATHS per day at the 50, 60, 70, 80,, 100and now, the 200 DAY mark. The average is still rising which, as the average started low, is not good news. What can I say? Mask Up, folks.
MATHSPIG is reporting in from lockdown in MELBOURNE, Australia, where mask-wearing outdoors is now compulsory, there is an 8pm-5am curfew and travelling more than 5km from your residence is banned.
Finally, theNew York Timespublished graphs that show the severity of the Coronavirus death rate compared with average weekly death rates. Here is the graph for New York City, which shows during the peak of the Covid-19 Crisis there were 6,000 more deaths per week than expected from the average weekly death rate, which was approx. 1,000.
The death rate was 6 times the average death rate. That is a terrifying statistic and explains why we are all in lockdown or are slowly coming out of lockdown. Meanwhile, in the rest of the world death tolls are still increasing.
Many statisticians are using 3-day and 7-day averages to track the Covid-19 death and infection rates worldwide.
Mathspig is using the total average of deaths per day since stats were first published from 22 JAN 2020. When this average drops … that will be a sign for cautious optimism. But not yet!!!!
