1. Could a planet made entirely of water exist?

2. What would the core be like?

3. What would happen if two water planets collided? In both the initial collision and the result afterwards and during.

The core would be water, because the planet is made entirely of water.

If two planets made entirely of water collided it would become one planet made entirely of water

>>

For some value of "entirely," yes. Obviously some other stuff is going to accrete in there. The core will be some supercritical fluid stage... hard to say exactly what its properties will be. A lot of solid material might work its way down there, though. Again, it's too hard to say. Hell, we don't even know what our own planet's core is like, much less some hypothetical one with all sorts of complicated physics that no one's ever investigated.

>>7706776

Right but what would the collision look like? I don't think the two would just have a smooth collision forming a super water planet. I mean wouldn't the forces involved create a shit ton of energy and such? Would it just be steam everywhere at the collision point. What the mass of the new planet just be A+B or would it less a shit ton of water in the process?

Double major in theoretical physics and pure maths. Double master in theoretical physics and pure maths. Double PhD in theoretical physics and pure maths. Double post-doc in theoretical physics and pure maths.

learning physics is relatively easy if you have a phd in math

learning math is required if you have a phd in physics

physicists generally don't have the same rigor as mathematicians and have very limited if any knowledge in algebra, set theory, number theory and other less practical fields but with their excellent background in other fields of math including advanced ones like differential geometry learning math for them should be easy

>>

>>7706789

>This is what mathematicians actually believe

Any good course in physics will require you ti take hard and rigorous mathematical subjects. You are not required to learn set theory but it complements when tou have to take topos or functional analysis. Geometry is essential to many modern areas in physics and you need a complete understanding to even attempt at a GR course.

Obviously we are not going to learn it the same way but you are implying that the subjects in physics lack...

problem with science is all the left wing nut jobs

>>7706708

Science doesn't get things wrong, people do. People are what say things and create higher meaning.

Science is a set of tools and a general framework. If it is returning incorrect results, either people are using it wrong, or people have "manufactured" some aspect of it wrong and it must be tweaked. These tweaks have been very few in number for quite a long time, so science getting things "wrong" in modern times is usually just arrogant and delusional people who have terrible risk assessment and error handling. In a lot of these cases, many people knew something was wrong before we even started (asbestos, tobacco, irradiated water). In others, we just rode the waves of "it's new and we know!" and "woops, we don't really know." Because people are shortsighted and stupid.

The sooner this difference is learned, the better. Fucking something up and cleaning up the damage later is absolutely not an acceptable attitude that should be condoned. It needs to be stomped out.

And that is why I study the only true science, Mathematics! No one can manufacture a result and no one can get it wrong, publish and be believed.

Who here is excited to work with TensorFlow after finals are finished? I'm new to making sense of big data and you may be too but Google has open sourced an easy to use suite of tools to help learn. Check it out if you're any type of scientist.

I play on a vanilla WoW private serve that is emulated to original WoW with raids and eveything.

I'm wondering could I use tensorflow/neural networks to do a 40 man Molten Core/ BWL/ Naxx raid all done by a program learning it via wipes (trail and error)?

I would obviously have to teach DPS/Tanks/Healers how do do their roles

This is pretty much how I study shit I really need to know.

I either stand in front of my white board, and give a lecture to my imaginary class, but usually I've just been making flashcards and using them throughout the semester. Making my time spent cramming almost non-existent.

So they recommend studying different subjects/courses per day. Seems kind of weird to me as when you get started on a homework/project it would make sense to continue until you are done, as you have everything in your short term memory.

>>7706588

I think they want to highlight that utilizing your short-term memory can make you feel like you understand something more than you actually do.

Here you go:

Sir Francis Galton, FRS (/ˈfrɑːnsJs ˈɡɔːltən/; 16 February 1822 – 17 January 1911) was an English Victorian statistician, progressive, polymath, sociologist, psychologist,[1][2] anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist and psychometrician. He was knighted in 1909.

Galton produced over 340 papers and books. He also created the statistical concept of correlation and widely promoted regression toward the mean. He was the first to apply statistical methods to the study of human differences...

It's been a while /sci/. I don't have a clever one, but here you go:

>You've just visited the doctor and have been told that you have microscopic hematuria. As it turns out, microscopic hematuria occurs in 10% of all people, but in 100% of people with kidney cancer, which occurs in .0002% of all people. What are the chances, given what your doctor has told you, that you have kidney cancer?

It does seem like that now that I think about it because the riddle is too simple. Here's a harder one for you, faggot:
