Really bad puns of physics

I love puns, I am a Punisher, meaning that I make bad puns. But these are terrible. They are so contrived!

But sometimes I don’t care because:

Calculating the maximum heel size for Lady Gaga’s shoes

gaga_shoes

I get all my news from Fox News, especially important science news. Like the height of the Lady Gaga’s shoes and the news that playing Tetris is good for me. Fox News is the only network I know that will break the presidential address to announce important breaking story that like “Paris Hilton was spotted wearing sun glasses today.” Their news reporting is unparalleled.

So I spotted this story about Lady Gaga’s shoes on Fox News.

The physicist in me wondered: how high can Lady Gaga’s heels be? Turns out, there’s a formula for that. Physicists at the Institute of Physics (London, UK) have devised a formula that high-heel fans can use to work out just how high they can go. Based on your shoe size, the formula tells you the maximum height of heel you can wear without toppling over or suffering agonies.

h = Q x(12+3s /8)

h is the maximum height of the heel (in cm)
Q is a sociological factor (see below to work this out)
S is the shoe size (UK ladies sizes). This factor makes sure that the base of support is just good enough for an experienced and sober, high-heel wearer not to fall over.

‘Q’ is defined as follows:

p•(y+9)•L
Q = ———————————-
(t+1)•(A+1)•(y+10)•(L+£20)

The variables are:

p – the probability that wearing the shoes will help you ‘pull’ (in a range from 0 to 1, where 1 is sexy high and 0 is stick to carpet slippers). If the shoes are a turn-off, there’s no point wearing them.

y – the number of years experience you have in wearing high heels. As you become more adept, you can wear a higher heel. Beginners should take it easy.

L – the cost of the shoes, in pounds. Clearly, if the shoe is particularly expensive, you can put up with a higher heel.

t – the time since the shoe was the height of fashion, in months (0 = it’s the ‘in thing’ right now!). One has to suffer for one’s art, and if the shoes are terribly fashionable, you should be prepared to put up with a little pain.

A – units of alcohol consumed. If you’re planning on drinking, be careful to give yourself a little leeway for reduced coordination.

Lets see if we can apply this to lady Gaga.

P=1 – How sexy one would look. Well, these would really be sexy in a video.

y=10 – number of years in a high heels – I think she has been doing this for 10 years

L=1,000 cost of the shoes in UK pounds. (off the shelf shoes cost $250 (150 pounds), so the 1,000 pounds for custom shoes by Alexander McQueen sounds right; this is not a critical number)

t= -0.5 How long has it been since these shoes became popular. Yes, a negative number since it will come in to fashion at a future date when the music video comes out.

A=0 Amount of Alcohol. Lady GaGa drink alcohol? Never. She has a disreputation to uphold. She might do Coke but not alcohol…

So Q= 1(10+9)(1000)/(0.5)(1)(20)(1020) = 1.86

She is 5’1″, and apparently wears size 5.5 shoes. (Too many unreliable sources, but 5.5 is the consensus). We need to convert this to UK size. (chart here)

US shoe size 5.5 is sale as British size 3.

So h=Q x(12+3s /8)= 1.86x(12+3(3)/8) = 23.6 cm = 24.4/2.54 inches = 9.6 inches.

As the Fox News informed me, the size of her heels were 10 inches..

Amazing… Physics Rules…

What keeps lady Ga Ga from falling over while wearing 10 inch heels? Physics – of course.

For lady Gaga, with billion Youtube views of her videos, the Q factor can be pretty close to -1, so she can technically wear shoes with infinitely high heels.
