However, it reminds us all of the parable (nice word that word ‘parable’) of the Tsar and the Peasant. The peasant challenges the […]
The following graph came with a slider to change the number of people affected by the Covid-19 virus. However, there are no x or y-axis scales, therefore giving no really helpful information for the number/ratio/percent of infected people that will enable medical systems to cope. In other words, it is a rather simplistic graph that […]
A mathematician who studies the spread of disease explains some of the figures that keep popping up in coronavirus news. Adam Kucharski studies how diseases spread, but he’s not handling viruses in the lab ortreating sick people in the hospital. He’s a mathematician at the London School of Hygiene & Tropical Medicine, and he uses […]
British researchers have published a new map predicting the global spread of the novel coronavirus over the next three months. The graphic is based on the mobile phone and flight data of 60,000 of an estimated five million Wuhan residents who fled during the critical two weeks before the outbreak city was placed under lockdown.

The coronavirus is spreading rapidly in China and is now appearing in different countries. Flights, trade and contact is being limited to the source region in Wuhan. This shocking event follows a mathematical model – one based on statistical probability. This video looks at what “going viral” means and begins with the analogy of […]
New of the fast spreading coronavirus is cause for deep concern, as well as action to contain those who have been affected. However, H3 noticed a rather erroneous graph which attempted to compare coronavirus with the SARS virus. What is wrong with this representation? (see the Post Support column for a possible answer):
