In nearly every Action Movie our hero possibly holding hands with his love interest will run and jump ( just in time ) out of the way of explosion. eg. Man on Fire (2004) with Denzel Washington, The Marine (2006) with John Triton, Mad MAX FURY ROAD (2015) with Charlize Theron and Predator 2 (1990) with Danny Glover .
We will use car bomb stats that come from the U.S. Bureau of Alcohol, Tobacco and Firearms. (We in Australia can only assume this bureau exists because, um , there are many exploding cigars in America.) You will find these at Car Bomb Response.
Here are just a few of the popular disaster movies: Avalanche (2001), Earthquake (1974), Armageddon (Involves meteors 1998), Deep Impact (More meteors 1998), 2012 (Tsunamis, earthquakes, the lot. 2009), Twister (tornadoes 1996), Backdraft (Fire. 1991) and Towering Inferno (They don’t make thunderous movie titles like that anymore. (1974)
But what percentage of people involved in, say, an explosion suffer from SHOCK! There are many statistics about Post Traumatic Stress Disorder (PTSD) available. In one excellent study in The National Centre for PTSD Journal involved an explosion in a paint factory in Norway (1976), the 246 employees were ranked for their exposure to shock as follows:.
A. 66 Narrow escape
B. 59 Involved but not in danger
C. 121 Not present on the day.
80% Group A suffered shock and PTSD. Both Groups A & B showed symptoms of PTSD 7 months later. If, say, a plane crashed into your school sports field and your class survived with minor injuries calculate how many students in your maths class would go into SHOCK and how many would be left to take action using the above statistics.
These stats can also be used as a fraction or decimal exercise using 0.8 or 4/5 as the fraction of students in shock.
The names Bond, James Bond. In Moonraker with Roger Moore (1979) 007 jumps out of a plane without a parachute to avoid an assassination attempt. He catches up with, Jaws, arch-baddie, in mid-air and takes his parachute. Jaws survives his fall by landing on a big top circus tent.
In Point Break with FBI agent Johnny Utah, Keanu Reeves, leaps from a skydiving plane after Patrick Swayzes’ characer, Bohdi, who has taken the last parachute. Utah catches Bohdi in mid-air, and after a tense confrontation with a gun, both survive using Bodhi’s chute. The remake was in 2015.
There are more movie and real life stories at the Free Fall Maths link.
Note: We’ll assume Bhodi and Utah have equal horizontal velocities (plane exit velocity plus wind) so the following calculations only involve the vertical or falling velocity. The terminal velocities used for Bhodi and Utah are realistic estimates.
There has been a real world Witches Vs Zombie Fight.
The witches of the Haunted House in Salem, Massachusetts, are at war with the Zombies of The Nightmare Factory nearby. A witch tripped a Zombie who was wearing a straight jacket!!!! And … read it for yourself in the Daily Mail, UK.
*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.
Tarantino, being a connoisseur of Fake Blood, used several types of Fake Blood in the film Kill Bill II ranging from good splatter to free-flowing blood. According to one fanzine, in this film, Uma Thurman killed 88 opponents with a sword. So the numbers(above)are in the right ‘blood-soaked’ ballpark. More survival math (The Hunger Games)here.
