First, there was PHOTOSHOP!
Marie Claire Magazine, claiming to support real women and real body sizes, ran a survey in 2010 to see, which body size 6,8, 10, 12, 14 or 16, was preferred by the Australian public. There she is below, 59% of readers voted for Size 12.
Size 12
See the Mathspig Post: How they photoshop supermodels’ legs here.
In the same issue, the model below appeared in an ad. Her legs have been photoshopped. How does mathspig know? Do the math.
Model with 89% longer legs.
Now websites are advertising AI models.
How fake will they be? They don’t have to create freakishly long-legged AI models. Ai could generate fashion models of any size … or with 3-legs and 2 heads. Though the 3-legged model may not sell many brand-name jeans. But here are some examples Mathspig found and compared, first to our Size 12 model, then to our Size 6 model.
So AI can produce a range of AI models from realistic to ridiculous. But your eye sees the ridiculous pics as OK, leaving you with unrealistic expectations of body proportions.
Of course, some AI images can be hilarious.

With the World Fuel Crisis in play, this post from 2014 seems more relevant than ever.
Note: All ‘imaginary’ human fat will be sourced from Liposuction facilities.
Of course, in heavy traffic you are burning up the bio-fuel/fat getting nowhere.
Fuel Consumption (F) can plummet, even for the Mini, from 3.4 kg/ 100 km to 6.8 kg/100 km to 8.8 kg/100km. You may as well get out of the car and walk!!

This April Fool’s Math Test has been soooo popular, it deserves a reboot.
Tell your year 8 or 9 students that this test is designed to test their ability to concentrate and use logic while doing a challenging test under pressure.
Tell students to circle or note the ‘correct’ answer. Then wait to see how long it takes them to think you have totally lost the plot! You can make copies of the test using the PDF links below or project it onto a Smartboard, then put the answers up later.

Air resistance is a significant factor used by ski jumpers to increase their jump distance.
Ski jumpers crouch going down the ramp to reduce their X-section area and therefore their air resistence. Once they leave the ramp, ski jumpers try to increase their X-section area to increase their air resistence like Ski Divers to slow their vertical fall. But they have to land safely, so they keep their skis at a minimum angle.

Abby Hughes, USA, practicing in a wind tunnel.
Abby Hughes, USA, in the air
Here are the X-section areas for Abby Hughes:
Mathspig calculated the X-section area by the old-fashioned method of counting squares and rounding off the final count. Mathspig sized the two pics of Abby Hughes so that her head was the same size in both pictures.
Here is the formula for Air Resistance of Drag:
D = ½CApv2
Where C is the drag coefficient or constant, which depends on the shape and spin of an object. It is found by testing the object in a wind tunnel.
A is the X-section Area,
p is the density of the air and
v the velocity of the object.
More here.
As Abby Hughes has tripled her X-section area in the air, she will have tripled the vertical drag during her jump. This will slow her descent.

Chocolate contains a poison called Theobromine.
LD50 for Theobromine for cats is 200mg.
LD = Lethal Dose. LD50= Lethal Dose for 50% of the population. Cats in this case. This is how poison toxicity is measured.
According to The Royal Society of Chemistry, cats are hypersensitive to Theobromine but, as cats cannot taste sweetness, they are rarely poisoned.
