How do we know what lies deep in the Earth's surface if we have never actually observed it?

Lots of hot metal under immense pressure. Not that much else desu

50 years after the Apollo program, NASA will have a rocket that costs twice as much per launch as a Saturn V, took twice as long to develop as the Saturn V and can carry half the payload of a Saturn V.
How the fuck did that happen?
Capitalism.
America spends only 19 billion dollars for NASA.
America spends 550 billion dollars for the army to do useless wars in the Middle East.
Quality assurance.
We've got higher standards then we did when there was a political space race between two big egos.
The stuff that's getting build now is much more advanced than we had and worth the higher R&D costs.
Sure there might be some corruptions but it's impact is limited.
Just joking... if Spacex can provide the same payload at the fraction of the costs then they can as well.
What do you guys study in your spare time for fun? Do you tend to focus on one subject, or broaden them? I am trying to learn as much as possible in all subjects. Those subjects are:
>Math (Currently majoring in this)
>Physics
>Chemistry
>Biology
>Astronomy
>Earth Science(s)
>English (language and literature)
>History (US and World)
>Economics
>Psychology
>Music
>Art
>Anatomy/Physiology/Medicine
>Engineering
>Computer Science
Am I missing anything? Post your list of subject(s) that you study
>>9028435
How the fuck do you manage to have the time to study all of those?
>>9028436
I don't that's the problem. But since I'm on summer break, I am basically only focusing on History, Art, Music, and Economics (literally just reading basic economic articles). When I am in school, I have Math, Physics, English, and CompSci courses so that's all I focus on. I was trying to find some ways to manage my time better to study others.
Do you study anything in your spare time?
That's a lot of stuff to learn.
I'm studying physics in college and learning chemistry in the summer break.
I have a professionally tested iq of 135 and I'm of German and Irish descent statistically speaking how much of an iq boost will I confer upon my sons if I impregnate an ASHKENAZI girl pursuing a PhD in neuroscience?
Jewish Ashkenazi girls always get along with me for some reason I'm thinking of biting the bullet.
Non.
She will abort and you will go to prison for rape.
I know this feel anon.
Irish. Huge Cranium. High IQ. Jewish girls all over me.
What do....
Do Ashkenazi girls like to race mix with Koreans in medical school?
What is the best way to use hydrogen as fuel to generate electricity?
Annihilation with antihydrogen

Antihydrogen doesn't exist.

there is literally no hope of ever getting corporations to do anything except what will make them the maximum money in the short term. And since the worlds governments are completely at the bidding of the same corporations literally nothing will be done.

What's the most versatile engineering field?
Material.
Electrical by far
>>9048808
Mechanical engineering. How the fuck did I end up doing AI research for chemistry? I honestly don't even know how this happened.
I read that Lee Hsien Loong was the Senior Wrangler (first place in annual exam) when he was reading mathematics in Cambridge, and his tutor believed he could become a mathematician.
tfw ywn have a math genius be your dictator

>Can scientists be good politicians?
Well Merkel has a degree in Physics and she allowed 1,000,000 muslim refugees to freely come to Europe. So yes, Scientists can be very good politicians because being a STEM major automatically means they know whats best for the country.

Singaporeans are obsessed with this technocratic shit. I won't say it's without merit, but there are other qualities people ought to value in their leaders. This tendency of theirs certainly contributes to the stifling nature of their society
>>9048041
How can a scientific background lead to stifling??
What would've happened to math if we were born with six fingers on each hand & toe instead of five?
>>9047642
Uh... nothing? I don't understand how having an extra finger per hand and toe would change the way we saw math.
>>9047645
Think about it. How humans created letters for math in the first place, they used their fingers, 1 finger, 2 fingers etc...
The letter 0 has a value (which is nothing) but also signifies an end or a start of a new sequence of numbers. for example, the 0 in 10 is a sign that a new sequence have started which will im the number 19 and than 20 will symbol a new set of numbers.
So if we created our math letters with our fingers, we wouldve had to add two new number (their value would stay the same but the way we wouldve written those two numbers would be different).
>>9047642
We'd use base 12 instead of base 10. This would actually be better, since 12 has 4 divisors while 10 only has 2.
Are chemical engineers exclusively dedicated to unitary operations and transport phenomena?
Do they even use chemistry at all?
>>9047100
>chemical engineering
why would anyone want to do that? do you hate yourself?
>>9047109
I don't hate myself THAT much, but recently i had a disscusion with a professor who claimed that all other courses's importance pale in comparison to the unitary operations.
I just happen to think reaction engineering, materials and catalysis is just as important.
>>9047100
Not really. You are an industrial engineer but with chemicals. You also get paid alot more than a chemist.

Hello /sci/,
recently, I am becoming concerned with fluoridation of water supplies, could any of you help answer the following questions for me?
>is there a safe dose of fluoride to take regularly?
>does fluoride bioaccumulate in the body, so that even low doses build up over the years?
>does fluoride actually prevent tooth decay?
>do you consider the levels of fluoride found in drinking water to be safe?
Thank you.

The average loss in IQ was reported as a standardized weighted mean difference of 0.45, which would be approximately equivalent to seven IQ points for commonly used IQ scores with a standard deviation of 15.* Some studies suggested that even slightly increased fluoride exposure could be toxic to the brain. Thus, children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas.
>>9048686
nope, it's clearly a mind-control mechanism employed by the US government, along with iodized salt, globe-earth, and chemtrails.
>is fluoride in our water safe?
yes

I can't stop watching Elon Musk talks and future Artificial intelligence. I think software and things like that will be very important to me and wondering what kind of software/programming/coding I should learn to be better at all of that.
I'm even considering switching into software engineering.
Can we talk about the future of robots and the impact tey will have on all of our lives?
don't switch, you will be happier with the money you'll soon be making than you would competing with Ranjeev and Cho
>>9048483
I want to learn coding in my spare time. This shit is amazing.
>>9048504
First step: stop calling it coding
Read your SICP and stop trying to predict the future.
So when people talk about the global flood in the bible with noah, people try to prove them wrong with fossils etc but im just thinking, isnt it impossible to have that much water on earth?
Am i right in saying theres been exacly the same amount of water on earth since its existance? give or take humans taking very very small quantities of water out on rockets etc. Or is it possibile every drop of water stored in the clouds rained evenly around the world until it was all gone, that at least most of the world would be flooded?
Also just to clarify i know this didnt happen, just wanted to look into the reasoning creationists use
>>9047660
>the reasoning creationists use
"God did it."
>>9047665
pretty much hit the nail on the head. But i mean they try to prove it with twisted facts on fossils and stuff but in my head before u even get to fossils surely there couldnt be that amount of water on earth period
SuspiciousObservers puts forth a theory in talking about our diminished magnetic field while entering a solar minimum. Strong CMEs can potentially make it through our weakened field and introduce large amounts of free hydrogen into the upper atmosphere along with copious energy necessary to synthesize water from the oxygen already present. This has the potential to cause a large flood and has very likely happened in the past. In fact this is potentially how a good amount of our current water was produced rather than by the accepted ice meteor bombardment.
Add in that many cultures have similar flood stories pointing to a very possible real world global event thousands of years ago and Noah's flood could have been very real.
