all day, every day. how many pills does the patient need if they are going to take the pills four times a day for seven days and need to take one and half pills? the dose needs to increase by 200 mg and is at 400 mg... mean blood pressure is 1/3 systolic blood pressure plus 1/3 diasytolic blood pressure. the dose needs to go down by 10%. and that's just the math i did in the last two hours that i can remember...some of it's simple, some of it's really simple...

A neurologist working with patients with
epilepsy. Every day she runs EEGs on the patients, where you hook
electrodes to the heads and plot the (microscopic) voltage differences
between various parts of the brain. If there are irregularities (caused
by tumors, lesions, et cetera), there are irregularities in the
electrical signals. She needs to take sums or differences of the
voltages, and can apply various digital filters to the data to
eliminate noise, or to eliminate a known signal from the rest to see if
there are irregularities in what's left. The frequencies of the signals
are interesting, but they come in a horrible mix, so the filters
effectively do various mathematical transforms to the signals, such as
Fourier transforms and many others. It's basically digital signal
processing, but with 20 signals, all of which are related.
Radiologists use even more math in related ways, but I don't have any
direct experience, so I can't give you details, but it would be a good
lead to follow up. The only example I know of for sure in this field is
when the doctors use radiation for killing a cancerous tumor. If you
just use one beam, it'll kill everything in your body in a straight
line from the x-ray machine straight through, and that's not so good.
So multiple beams (or moving beams) are used so that a little radiation
goes through lots of paths, but it all hits the tumor, so the tumor
gets totally "fried" and the other parts get a mild "sunburn". (Of
course, I'm sure the docs don't say "fried" and "sunburn", but you get

When they bill you they are very good in calculating inflated math. Did you know a "specialist" doctor can charge you over $300 for their time of 3 minutes to say hello to you and move your foot back and forth twice on each side?

15 minutes divided by 5 appointments = 3 minutes per patient
5 appointments x $300 each = $1500.00.
Not bad for 15 minutes of work.

A lot of the math they use is applied and formulaic. Such as, dilution problems. C1V1=C2V2

They might need to use proportions so that they can prescribe the right amount of medicine.

Certainly not to keep track of their money. Nobody can count that high.
