Halloween Math: IT Chapter 2 vs Kill Bill Vol 2 in Fake Blood
October 15, 2021
Halloween Blood can be found @ Party City
Stage blood @ Stage Makeup
Movie Blood @ Thomasfx
*Note: These were the fake blood volumes quoted 12 years ago when I was first researching fake blood data. I have noticed the numbers on various chat platforms have inflated the volumes in the last 12 years.
*Note: Rounding off the initial volume eg. 0.06 pint (0.028L) then up-scaling that volume to 36,000 pints (17,000L) introduces a significant error in the final calculations.

How the UK Aced Covid, sort of …
June 29, 2021
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.
DAY 500 COVID-19 … some curious stats
June 7, 2021
Mathspig has tracked the Covid 19 Stats through the Worldometer tracker and calculated the AVERAGE NO. DEATHS per day at the 50, 60, 70, 80, 100 , 200 DAY and the 1 YEAR mark ..
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.
Vaccine math. Results vary because …
March 26, 2021According to the AstraZeneca Media Release, 22 March 2021, “The AstraZeneca US Phase III trial of AZD1222 demonstrated statistically significant vaccine efficacy of 79% … based on 32,449 participants accruing 141 symptomatic cases of COVID-19. The trial had a 2:1 randomisation of vaccine to placebo.”
“A careful review of all available safety data of more than 17 million people vaccinated in the European Union (EU) and UK with COVID-19 Vaccine AstraZeneca has shown no evidence of an increased risk …”
Update:
The Washington Post, 25 MAR 2021
An updated company analysis of the coronavirus vaccine developed by AstraZeneca and the University of Oxford showed that the two-shot regimen was robustly effective — 76 percent at preventing symptomatic illness — according to a news release from the drugmaker late Wednesday.
Among people 65 and older, the vaccine was 85 percent effective, the company reported.
New York Times, 9 APR 2021
UK plus & 30 EU countries have administered 34 million AstraVeneca doses and report a blood clot condition in 222 patients and 18 fatalities.
Risk Factor for blood clots = 1: 153,000
Risk of death ~ 1: 2,000,000
Many countries including Australia advise the use of the AstraZeneca vaccine for the 50+ age group as the blood clot condition appears mostly in younger patients.
Death by Chocolate: Yes! Chocolate can kill. But how much would kill you?
February 24, 2021Choco Yum Yum! Mathspig lervs chocolate. But did you know chocolate can kill you?
Chocolate contains a chemical called Theobromine. This alkaloid ( other alkaloids include cocaine, nicotine, caffeine, and strychnine) can kill humans. More info Wired Magazine.
How much chocolate is too much?
Firstly, the darker the chocolate the more Theobromine it contains.
According to About Chemistry based on the highest possible toxicity:
* Vetmedicine: Cooking chocolate contains 8-10 times the Theobromine in Milk Chocolate.
According to Wired large doses of theobromine may cause “nausea and anorexia ….. sweating, trembling and severe headache.”
The Royal Society of Chemistry notes that chocolate does not contain caffeine, but theobromine induces similar symptoms.
LD50 for the lethal dose for 50% of the population for Theobromine is:
1000 mg/kg 0r 1gm/kg of body weight in humans
