OMG! The Best Ever ALGEBRA Promo and it’s written by AI

So Mathspig asked Chat GPT to:…………..

Describe algebra in the style of Mathspig

Alrighty then, buckle up your math belts and get ready to rock the world of algebra! Algebra, my math-hungry amigos, is like the ultimate superhero of mathematics. It’s all about unleashing the power of unknowns and solving the most mind-boggling puzzles known to humanity.

In the realm of algebra, we ditch the boring old numbers and bring in the big guns: variables! These sneaky little devils represent unknown quantities that are just begging to be discovered. They’re like the Sherlock Holmes of math, always on the hunt for clues to crack the case.

Equations are the name of the game in algebra. They’re like the secret codes that hide the answers to life’s greatest mathematical mysteries. We tinker and tamper with these equations, using super cool math moves to bring order to the chaos. We combine like terms, simplify expressions, and rearrange the pieces of the puzzle until we uncover the truth.

More rules here

But wait, there’s more! Algebra isn’t just about solving equations; it’s about exploring patterns and relationships. It’s like a math treasure hunt where we unearth the underlying structure of the universe. We create graphs, plot points, and analyze the data to reveal the secrets that numbers and formulas hold.

Algebra is all about flexing your math muscles and honing your problem-solving skills. It’s a mental workout that strengthens your logical thinking and boosts your brainpower. It’s like math aerobics for your mind, keeping you sharp and ready to tackle any mathematical challenge that comes your way.

So, my math-loving amigos, embrace the power of algebra. Let your curiosity run wild, and let your mathematical genius shine. Unlock the hidden mysteries, unravel the enigmas, and conquer the world of numbers with confidence and style. Algebra is your superpower, and with it, you can conquer the mathematical universe! Mathspig, out!

7. You can safely jump from a burning skyscraper/bridge/aircraft into water.

Angels and Demons (2009) Tom Hanks character, Robert Langdon, hero of Dan Brown’s jumps from a helicopter and falls thousands of feet into Rome’s Tiber River and survives, of course.

Ahhhh! Look up. It’s raining Tom Hanks!!!!!The Hulk (2003) The Hulk hops from the Golden Gate bridge onto a jet fighter, whose pilot tries to get rid of him at high altitude. The Hulk falls off and plummets many thousands of feet into the bay. He survives.

There are 2 factors we must consider when jumping or diving from a great height:

1. Surface Impact

2.Water depth 

1. Surface Impact

According to the Free Fall website falling into water is not a good survival strategy. 

‘Someone falling without a parachute from more than 2,000 feet or so would be falling quite a bit faster than 100 miles per hour (161 kph) The folks who have survived falls into water have had streaming parachutes above them, which probably slowed their falls to the 60 mph range (97 kph). Having a streaming parachute helps in another way because it aligns the body in a position where the feet enter the water first.’

The website goes on to explain that water is an INCOMPRESSIBLE FLUID. It’s like landing on concrete. Landing in mud, on snow, on trees, on circus tents etc helps break the fall. Moreover, jumping off a bridge into turbulent sea may be safer than jumping into calm water.

On 24th Oct 1930, Vincent Kelly, 31, while working on the Sydney Harbour Bridge fell 170 ft (52 m) into Sydney Harbour and survived.

A champion diver he did several summersaults and landed feet first. He broke a couple of ribs as he did not enter the water at a perfect RIGHT ANGLE but rather a few degrees off perpendicular..

2. Water Depth

The next issue is, if you are going to dive or jump into water from a great height and, miraculously, survive the impact, how deep should the water  be?

Olympic divers often practice their dives in a bubble pools (like a spa). This reduces the impact for a bad dive but the water must be much deeper. Sports Smart Canada recommends a water depth of double the height of the drop. But is this realistic if, say, you are jumping or diving from the top of a waterfall into aerated water.

You can work out approximate depths needed if you were jumping into calm water from heights such as below:

How deep do you plunge? The answer is surprising because, in fact, you decelerate really fast in water.

See REd Bull Jump Science here

Thanks to Rod Vance  for the Fluid Engineering Calcs (done by hand … not by computer program) for calculating the depth of water when your feet stop moving. That is the minimum depth of water needed for the jump (See graph below)

NOTE: Even with this fancy maths assumptions must be made about the transition epoch-half in/half out of the water.

 Assuming you survive the impact and you breath out through your nose – to stop water going up your nostrils really fast- then you will not go any deeper than approx 4 m or 13 ft from a platform of 20 m (65 ft) or less.

If you’re diving into water from, say, a helicopter as in the Demons & Angels movie you don’t need extremely deep water. Assume Langdon was at 100m (328 ft) or the height of The Statue of Liberty(above) or a 33 story building  when he jumped, then extrapolating the graph (above), maybe, a depth of 5m (16 ft) would do.

If you want to see what looking down from a 58.8 m (193 ft) platform looks like check out thisWorld Record Jump by Laso Schaller.

8. You can survive any amount of beating in a fight.

 

 

 

 

Every action hero gets into a fistfight. James Bond, Jason Bourne, Indiana Jones. Then there are all the stars known for their fight scenes. Sylvester Stallone ( Rocky),  Arnold Schwarzenegger (True Lies), Jackie Chan (Any movie), Bruce Willis (Die Hard 1,2, 3 etc), Mel Gibson (Lethal Weapon I, II, III etc), Jean Claude Van Damm (Blood Sport, Street Fighter), Brad Pitt (Fight Club), Fast & Furious 1,2,3 and so on.

But can the human body take this punishment?

We can work it out. Measurements taken at The University of Manchester have shown that local boxing hero Ricky ‘The Hitman’ Hatton really does live up to his name. (DailyScience)

Ricky ‘The Hitman’ Hatton can pack a punch!!!!! 

Similar results were found at Uni Manchester BBC (Force of boxer’s punch measured)

So one punch is equal to being hit by a car …… if only for a split second!!!!!!!!!!! Nevertheless you can be killed by this one punch.

You’ll find some great punching physics here

10. You can out run a lava flow … METRIC

This is a rework of a previous post with full calcs.

Every volcano disaster movie from Volcano (1997) with Tommy Lee Jones to Dante’s Peak (1997) withPierce Brosnan someone somewhere tries to out run a lava flow. Is this possible?

The answer is maybe. You will find everything you want to know about lava flows here.

On January 10,1977, at Nyiragongo lava sprang from the sides of the volcano moving at speeds up to 40 miles per hour (60 km/hr). About 70 people were killed.

 Measuring the temperature of lava. Photograph by R.L. Christiansen, U.S. Geological Survey, January 9, 1973.
The fastest Lava flows recorded were in Hawaiiin 1950 when Mauna Loa erupted. The lava traveled at 10 kilometers per hour through thick forest. But once the lava flows became established and good channels developed, the lava in the channels was flowing at up to 97 kph.

Speed of average sprinter = 16 – 24 kph

 

Can you out run a lava flow?

You would be scorched after 3 minutes!!!! 

10. You can out run a lava flow … USA UNITS

Speed of average sprinter = 10 – 15 mph

Can you out run a lava flow?

 You would be scorched in 33 seconds!!!

Dangerous Math: Death by Snake, Spider, Quad bike, Kangaroo, Raccoon and Vomit

It’s almost summer in Australia. In Melbourne we’ve had floods, mosquito – mozzie- numbers surge and, last Wednesday, I nearly stood on a Tiger Snake that was escaping the floods near the Yarra River! 

This post, however, is really a PR exercise for sharks. We fear them. We’re horrified by the thought of being eaten alive!!!. We only have to hear the soundtrack from JAWS to feel the fear. Then we see news footage like the attack below and think it happens all the time. Look at that fin. It’s enormous! But sharks are not THAT dangerous. We really need to look at the statistics to understand the level of threat. See below.

Why do we fear sharks? Look at the numbers. REALLY. Show your students. What about stairs??? Quad bikes? Chairs? Bees? That’s when you should feel the fear!!! We are irrational beings. This is why we need maths. We can make rational decisions using maths. There is also a safety message here. The maths speaks for itself. We won’t hammer it.

THE MATHS:

There is lots of maths you can do with these tables.

• Bar Graphs
• Pie Charts
• Ratios (What’s the ratio of death by Snake to Quad Bike?)
• Fractions (Show death by jet ski to falling down stairs as a fraction)
• Percentages
• Powers to the base 10. How many deaths occur in each country per 100,000 or 1 x 10⁵ head of population for, say, Quad bikes or ATVs? We can use these numbers to compare death rates and find out how dangerous riding a Quad bike is in each country.

……..Population Data 2022: 

……..Aust…26 million = 26 x 10⁶

……..USA…332 million = 332 x 10⁶

……..Canada…38 million = 38 x 10⁶

……..UK…67 million = 67 x 10⁶

But we’re doing this for the SHARKS!!!

DART vs ASTEROID: Middle School Math

DART is a test

of NASA’s planetary defence plans.

AND IF YOU GOOGLE ……..

 DOUBLE ASTEROID REDIRECTION TEST

                                       Guess what?

The DART(Double Asteroid Redirection Test) mission was launched on Nov. 23, 2021, atop a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California.

It is the size of a small vending machine and it has been travelling through space for 10 months.
