Why I Love Math - Bra & Tits

If you have a son who is having trouble in math at school, you need to find a way to motivate him.

This is how.

You need to tell him about this thing called Bra. You need to tell him for the rest of his life he will be chasing for the thing in that picture below. So the sooner he learns something about it, the better. Don't concentrate on the bra, it's the things inside.

Well, that's a bikini top but I like her tits. So sue me you fucking moron.

Brassiere

From Wikipedia, the free encyclopedia

A brassiere (pronounced UK: /ˈbræzɪər/, US: /brəˈzɪər/; commonly referred to as a bra /ˈbrɑː/) is an article of clothing that covers, supports, and elevates the breasts. Since the late 19th century, it has replaced the corsetas the most widely accepted method for supporting breasts.

Female-bodied individuals wear bras for a variety of purposes: for support, to improve the shape of breasts, to reduce or to enlarge the perceived breast size, to restrain breast movement during an activity such as exercise, to enhance their cleavage or to facilitate nursing. Most bras are designed to be form-fitting and to lift the breasts off the chest wall if they sag and to restrain their movement. Bra designers strive to produce a garment that is both functional and aesthetically pleasing.

For some people, the bra has become a garment with erotic significance and a feminine icon or symbol with political and cultural significance beyond its primary function. Some feminists consider the brassiere a symbol of the repression of women's bodies.^[1] Culturally, when a young girl gets her first bra, it may be symbolic of hercoming of age.^[2]

THAT IS A BRA.

What then does math gotta do with it????


Calculating cup volume
One of the principal functions of a bra is to elevate and "support" the breasts, that is, to raise them from their normal position lying against the chest wall. This is considered the defining characteristic of the bra: supporting the weight from the back and shoulders, as opposed to lift solely from below (as corsets do).^[1] Over-reliance on the shoulder straps for support can lead to poor posture, back pain and neck pain due to pinched nerves. In a well-fitted bra, 80% of the breast weight is supported by the chest band, something which is particularly important to those with larger breasts.^[16]

The average breast weighs about 0.5 kilograms (1.1 lb).^[23] Each breast contributes to about 4-5% of the body fat and thus 1% of the total body weight of an average female-bodied person.

The major engineering weakness of the bra, particularly if poorly fitted, is that it acts as a pulley, transferring the weight of the breasts from the lower chest wall to higher structures such as the back, shoulder, neck, and head. This can result in pain and injury in those structures, especially for those with pendulous breasts.^[24]

The density of all fatty tissue is more or less constant for all women but the volume of the breasts can vary. Bra designers can calculate the volume of a brassiere cup in several ways depending on the shape of the breast. If the breast is round and essentially the shape of a half-sphere, its volume V may be estimated as ^[21]

where D is the diameter of the sphere, and r is its radius.

If the breast is shaped more like a cone, the designer might use a formula like the following:^[21]

where Db equals diameter of the cone's base and h equals the height of the cone. Other formulas can be derived as needed to design bras for differently shaped breasts.

The chest band and cups should provide support for most of the weight of the breasts, rather than the shoulder straps. Over-reliance on the straps for support can result in health problems for the wearer. In most bras the straps are adjustable by sliding fasteners, and are usually made of a stretchable material such as spandex.

Now tell him he needs to ace all his math classes or he is not allowed to touch any tits for the rest of his fucking life.
