hey /sci/

settle a bet for me - will drinking milk give me man boobs? or do i need to stop browsing /fit/ so much

if so, is drinking skim milk better? or same amount of estrogen

>> No.8774568


>> No.8774604

Milk of all types is healthy, but estrogen won't give man boobs, that is if you drink WAY to much whole or raw milk. That is fattening.

>> No.8774662

Picograms of estrogen in food are physiologically meaningless. Like worrying about formaldehyde in pears.

>Estradiol from dairy products is extensively inactivated in the gastrointestinal tract and only about 5% survives the first pass to the liver. Thus daily dairy product intake would supply only about 0.25% of the FAO/WHO upper acceptable daily intake of estradiol.

You'd get more from intimate contact. Skim is better due to less saturated fat though

That is probably for manufacturing.
if you actually delve into design then things become complicated.

And yes, I know the computer does a lot of it but you still need to be able to understand the results.
For example, anyone can put numbers in a CFD code, but you need substantial knowledge about PDEs and linear algebra if you want to set correct boundary conditions. Even more, if you actually need to code it yourself.

Get both degrees. I did it. It took one extra year to do. Engineer that took all tech electives in Mathematics.

>> No.8774761

those are the math classes by math department. mechanical engineering classes, especially higher level ones dealing with fluid flows, go deeper in terms of solving PDEs. also, as a phd studnet i was required to take at least 2 more graduate level math courses out of only 12 courses in total that are required.

discretization is another big thing. my university has multiple ME courses dealing with discrete math.

DiffyQ and linear algebra are as far in math as you need to go if you ever want to do anything practical or useful with your knowledge and skillset. Applying it to study of materials was fucking awesome for me.

After all the bullshit going on here about IQ. My hypothesis is that anyone >110 IQ(above average), good socio-economic background and good work ethics can make it into competitive courses like medicine, law and architecture and simply practice them in reality. However, if one decides to go into research, let's say, a Ph.D. in mathematics, one without a decent level of IQ will find it very difficult to see patterns and understand complex novel scenarios in the field.

My university entrance exam is the A levels. People breezing through school and getting A*A*A*A*, both you and I know are an exception rather than the norm, probably less than 0.9% of people get this grade, imagine how many within that get it without working much. The average IQ for medical students is 115, the average score of a medical student is AAA(Typical offer for medical school), so connect the dots, and holy fucking shit, IQ doesn't mean shit until you get to Ph.D. level. Even in MD programme, where memorizing is the game, IQ doesn't play that big of a role anyways.

Tl;dr stop blaming your fucking IQ and get your ass off the couch and start working. Work ethic and wealth is the key here.
