Why does this matter? Also, how the hell do you finish in 2.5 years? Summer courses all summer ever summer?

>>9100754
I'm assuming 2.5 years to be conservative, since these majors have the first year basically all being overlap courses, and presumably there are some potential elective overlaps in later years adding up to 0.5 years each major

IM ON A MISSION SCI

LISTEN UP:
THE FOURTH DIMENSION

IF YOU DONT ALREADY KNOW WHAT A HYPERCUBE IS GTFO

IF YOU DONT ALREADY KNOW ALL ABOUT DIFFERENT PROJECTIONS GTFO

NO BRAINLETS ALLOWED, Of course I can't enforce that so the criteria I'm specifying is just at least have basic understanding of what 4D space is and how it works. I don't want this thread clogged up with spoonfeeding about basic brainlet shit.

Now, my mission. I want to visualize in 4D. I want to get my internal imagination to actually understand what an axis perpendicular to x/y/z actually is on an intuitive level. I already can understand the basic idea of course, but I feel like a 2D creature reasoning about cubes, but only able to imagine lines.

So far I think my best bet at gaining this intuition is examining how 3D cubes rotate in 4D space. It seems this should come far easier than jumping to hypercubes right away. While we are pretty good at visualizing 3D from 2D projections..attempting to visualize 4D from 2D projections is kinda absurd. Luckily many apps for examining 4D objects allow stereoscopic views. Unfortunately I haven't found any app which has just a 3D cube in 4D space, instead they're all 4D hypercubes. Cool to look at and help understand the basic idea, not as useful for trying to actually give yourself a new perception.

Pic related, its a 3D cube rotating on XW axis in 4D space. I fucking hate how simple it is, ffs...its so obvious, when its getting 'smaller' its actually just getting farther away in 4D space, however I just can't seem to perceive what that really means. It still looks like a 3D cube turning inside out. I want to REALLY SEE what its actually doing

>>9099238
I'm just interested how it would even work. There could be very interesting race vs race vs race matchups with alphago playing itself due to the assymetric nature of the game.

The problem is the micro vs human input aspect. AI has tackled 1v1 poker already so it should be able to handle the "mindgames" portion of 6 pooling vs expanding vs standard play.

It will be much more interesting than Go in terms of watching it but I have a feeling the micro aspect is going to ruin any true human vs machine comparison. Not that it didn't have huge computational search advantages vs humans in go, but the 200ms human response time and physical input is just completely outclassed micro wise by a computer.

Kinda wish they had chosen civilization games.
>>
>>9099243
Honestly speaking, I think Alphago will beat the koreans easy.
There is already built in AI, and there were user map settings (modded maps basically) back in SC1 with upped AI difficulty.
Imagine some non brainlets with the budget try to make that on steroids.

AI will have perfect micro, so the only way a human could actually beat it is with some exploitative strategy.

Divide by the dominant coefficient to get a unitary polynomial.
[eqn]X^3 \,+\, a\,X^2 \,+\, b\,X \,+\, c[/eqn]

Substitute [math]X \,=\, Y \,-\, \frac{a}3[/math] to suppress the square term. You get something like:
[eqn]Y^3 \,+\, p\,Y \,+\, q[/eqn]

Suppose the solution is under the form [math]\sqrt[3]{u} \,+\, \sqrt[3]{v}[/math] and solve for these. You should come across the easy problem "find two numbers knowing their sum and product."

During freshman year of college, I studied 80+ hours a week and only attained a 3.73/4.0 gpa. However, things changed my sophomore year when I got bronchitis 3 times during my first semester and was given 3 rounds of antibiotics at University Health Services.

I did bad during the winter semester as well. My dog died and my engineering buddy unfortunately committed suicide. I was depressed while studying that year and only got a 2.9/4.0 my sophomore year. I could only study for maybe 42 hours a week maximum. (Note: I ,of course, know to chunk study as in 2 hour session with intermitten 15 minute breaks).

After all that, I can not seem to get back to my 80+ hour self. Please help me and give me the best advice you can.

A rigorous undergraduate program should've weeded you out already if it takes you 80 hours of studying a week to pass your classes.

That is a rather mean and an assumptive comment. Most of my classes are set to a 2.9 gpa average. For example, during the first semester of my freshman year, I got an A- in Calculus 1 by being in the 88th percentile out of 1000 University Students taking the course.

A 3.73 is good considering practically all my classes were curved to a 2.7 freshman year. I go to a top 20 engineering school too.
>>
>>9102563
I wasn't saying you get bad grades, I was saying if you need to spend 80 hours a week on undergraduate material you should probably start failing out by your junior or senior year.
Too bad universities are degree mills now so you'll get pushed through, and probably even have a decent GPA. It will be impossible to distinguish you from someone who can actually accomplish difficult work in reasonable amounts of time just by looking at "education".

Let's say the government lied, Stanley Kubrick filmed the video, all the rockets and ships were manufactured just for show, and a bunch of people were silenced to keep the truth from getting out.

Yes, because it harms NASAs scientific credibility, if i cant trust NASA in moon landing, how can I trust their data about climate change and so on?

Mirror retroreflectors on Moons surface used by independent observatories, Russian tracking of our space ships (Russia would have high motivation to expose any American lies during the cold war, especially in regards to the space race), by now the files would have been declassified if it was faked

Why do people believe that there are aliens out there? There is simply no evidence of that. People keep doing those stupid projects like SETI that give 0 result but they keep believing that aliens exist.

The same people that don't believe in God because of lack of evidence believe in aliens despite the absolute lack of evidence. They also create stupid excuses about why we never find those aliens: "muh Great Filter".

Grow up! Aliens are a fantasy!

whatever you say im going to say back
"There is simply no evidence of that."
Then if you attempt to provide evidence, i will question your methods and lack of understanding concerning the tools you use to provide the evidence.

They weren't being edgy. It's just a fact that every RTS and DotA type game had shit AI. You need to do a lot of complex tasks that are pretty much impossible to code for with traditional AI coding methods.

I think it's fair to not believe a piece of technology exists yet (AI good enough to beat a human in DotA) if it literally did not exist yet a day before

Look at you all. Life is just one big puzzle to solve. That's it. The individual who breaks out of our little puzzle world becomes God. As glamorous as that sounds, it's not. IQ tests are designed to see how well you can recognize patterns, High IQ = Higher brilliance. You yourself are a biological computer, Who cares where you came from. The Why will never be important until you figure out the What Where and Who. So use your cute little brains and help me figure out this universe. Stop labeling each other all these 'names' The mind is so brilliant. You yourselves are each magicians. If you think that you yourself are so such a person you will be come so such a person. Learn to recognize the patterns of our reality and you will excel above everyone else. Scores mean nothing, It's all just a game. Learn the rules mr. Smarty Pants. And Play It.

You arent in this life for anyone else. You are here to take what you can get.
When you realize somebody has something you dont, you justify it.
When you realize you have something somebody doesn't, you parade it.
When you aren't sure, you ask loaded questions until you are sure.

Convinced that there is a hierarchy to worth, with superior people who have it all at the top, and inferior people who have nothing at the bottom, you find yourself somewhere in the middle.
Looking up, all you see is assholes and concerned people looking down.
Looking down, all you see is shit and fearful people looking up.

Electrons are easy to manipulate, just put a potential difference in a conductor.
>>
Most quarks and leptons decay, not that quarks by themselves would be of any use.
Z and W bosons and Higgs decay.
Not sure about free gluons but I guess they interact too strongly.
Neutrinos don't interact strongly enough.
Photons are used in communications, but their logic components are not yet good enough for computation.

Basically electrons are great because they are stable and interact just the right amount, and then some stuff about electron orbitals. Simply having a rod of metal works as a medium because of free electrons. Logic is also comparatively easy to make because of semiconductors.

In communications you want less interaction, so photons are good for that. You can steer them around but they have very little attenuation. I suppose neutrinos would be even better if they didn't require massive isolated receivers.
