The main concern when jumping off a building is that the airbag (cardboard boxes) cover the drop zone.
The maths calculations involved in jumping off a building are straightforward. You might like to check out How Maths Solved a real murder.
Jump Height that Kills
It doesn’t take much of a fall to cause damage. Sean Hughes, professor of surgery at Imperial College, London. Says “From a height of 3m you could fracture your spine,” he says. “At around 10m, you’re looking at very serious injuries.” (The Guardian, 20 MAY 2014)
Stunt Jump from building from standing start
As this jump – as in most base jumps – involves a standing start:

Star Stuntmen
Star Stuntmen Monte Perin (pictured) has involved many films, including “Spider-Man,” “Star Trek, “Indiana Jones and the Kingdom of the Crystal Skull” and portraying Arnold Schwarzenegger’s stunt double in “Terminator 3: Rise of the Machines.”
Perhaps his most difficult stunt was landing his Harley in an open boxcar of a moving train for Disney’s 2008 Adam Sandler movie “Bedtime Stories”. In a career of over 25 years Perin has broken “almost everything” including both his arms, legs, knees, feet, ankles, several ribs, his back and his pelvis. See Confessions of a stuntman
Veteran stuntman Evel Knievel (1938 – 2007) was the pioneer of many stunt jumps. Here he is jumping 10 cars and 3 vans in 1973.
Boredomaccounts for nearly a third of the variation in student achievement.
Half of high school dropouts citeboredomas their primary motivator for leaving.
Boredom begins for Math students at Grade 6 when students (Common Core Standards, USA) tackle more abstract concepts such as linear eqns, exponents, probability, geometry and so on.
Math curriculums in the USA, UK & Australia all demand students solve REAL LIFE problems. Too often these are of the type:
Q. Ronaldo has tethered his goat on a 12ft rein in the corner of a 20ft square field. What area can the goat graze?
THE ANS: Who cares?
Simple.
Ask students maths questions which have answers they want to know.
Students really don’t care about Ronaldo’s goat, but here are some questions which involve intriguing answers they might want to work out. And many of these questions involve funny or age-relevant activities, which also helps engagement.
The average time it takes an audience at a conference to switch off is 11 minutes. Keep in mind this audience is, at least, being paid to be bored witless.
This idea comes from Burkard and Giuseppe @ the fabulous MATHOLOGER channel. Students can make a pattern called a cardioid that pops up all over math according to Burkard.
Follow these steps. There is a pdf file below the first diagram for printing exercise sheets.
And then watch the MATHOLOGER video for a really interesting explanation.
For an inverted pendulum near the top of its arc, there is no period, but the quantity √ℎ/𝑔 does represent a characteristic time scale for this system. The tree will take a few of these characteristic times to fall.
Mathspig hates seeing an old tree felled, but it does give us the necessary time data.
There are many assumptions in these calculations.
*You’d be hit by the tree trunk, not a branch which would hit you sooner.
*There is no wind pushing the tree over.
*The tree falling is an approx to a reverse pendulum.
It must be the off season. Or the heat in the Northern Summer. Or desperation. Reader’s Digest has just published 37 Math Jokes. Mathematicians are not known for the jokes. But here are 3 goodish ones.
ANS: He’ll stop at nothing to avoid them.
ANS: A roamin’ numeral.
ANS: Probably.
Here is a classic MATHSPIG JOKE:
And while we are being crazy cool kids here is a TED Talk on Mathematicians Dancing. I would call this a Mathfail because these guys DO NOT look as though they are having fun. Or, maybe, just maybe, the success of a joke or a dance is all in the delivery.
