I never once claimed I am smart. I just claimed you were stupid.

See? This is why I said you can't into logic. If you can't even follow a simple chain of implications then CS is right for you, as you don't even have to think.

Pros of going to a top tier university:
-Courses are more interesting
-People there are more intelligent and ambitious, more interesting to talk to, better societies
-More high quality networking events, conferences, etc. making it easier to meet the right people, learn more about the latest theories and developments in various fields, learn and understand what different jobs require, get an internship/job
-You'll probably get more financial assistance
-Much easier to get a competitive job: provided you are studying something serious and not going into a specialized field of work, what employers care about academically is the reputation of the university and grades achieved

Pros of going to mid tier university:
-Lighter workload
-Maybe you enjoy Mathematics a bit more
-You can spend all your extra free time being a memelord on sci

Pros of not going to college:

1. You don't have to pay 40k per year for 4 years
2. You can learn everything the college would have taught you by just buying the text books and going through them
3. Finish all the material 1 year earlier because college wastes a shit ton of time

Can anyone in aerospace engineering explain to me the benefits of designing the rear fins on drones to point down like that instead of more traditional rear wing designs that you see on airplanes?

Aero student here

First let's go over what tails are for:
Stability derivatives of an aircraft are quantities which essentially tell us if the aircraft is statically or dynamically stable. An aircraft with one or more + stability derivatives will diverge from its equilibrium further once perturbed. When designing an aircraft, you want stability derivatives to be typically negative, except for a handful of military cases requiring extremely advanced control software which have positive stability derivatives for manuevrability.

V-tails are typically used to combine the functions of horizontal and vertical stabilizers. They inherently couple yaw and pitching. So long as stability and manuevrability characteristics are okay, there is no advantage to a regular or inverted V-tail from this perspective.

However, depending on the aircraft, inverted V-tails may have advantages such as structural ones or being less affected by the wing wake.
>>
>>8991022
Airplane design changes are limited & constrained by regulations
(Thanks to EU & to the Congress of each country)
So for traditional airplanes there is less freedom to change the design.

Drones are new technology so are less regulated,
so there is more freedom to change the Design of drones.

that doesn't explain why it's done at all, other than "because they can"

>>8992381
In the times before the advent of Modern Computers. All tests were made in Labs, Wind Tunnels with small replicas/models/prototypes. There was no simulation software back then. To Create each replica/models/prototype in real life was time/cost expensive.

Now we have modern softwares that can simulate the aerodynamics for a more variety of design shapes & situations. Thanks to Computers.

We don't need to create hundreds of replicas anymore. We can experiment more crazy design with Virtual models & test them by Computer Simulation.

We then build a replica only for the final prototype.

But all of regulations that limits design creation were created on the previous century, these regulations limits design improvements for traditional airplanes.

Because that the design of commercial airplanes is now a bit stagnating, the good side is that it's stable & safe.

Drones & Top Notch Military Aircrafts Design are more Innovative & improve at faster rates.

the funny thing is those "evidences" are not supressed (I don't even know how you'd do that.) those are observation that are commonly used in the process of recreating and understanding earth's history.

The only thing is that, when you actually use a bit more than two neurons and a half they don't point to a global flood.
>>
>>8991130
Even if there were a great flood that covered the earth (there wasn't) why would it matter? I mean geologically it would be impressive, but its not like theres any evidence that your imaginary god made it happen.
>>
>>8991992
>This suggests that a third alternative is needed, especially as neither model fits into a young-earth scenario.

that's not how it works. If you got an observation that doesn't fit into your model, you modify the model, not the observation.

I know this may sound weird but here we go.
Lately I needed to write a presentation in physics, when I started diging into wikipedia and learning about quarks and quantum mechanics, I got really intrested.
I also enjoyed watching vsauce and channels related to science.
does abybody have any recommendations regarding books/other media like videos about phsics, chemistry, astrophysics, biology, technology, medecine etc...?
I really do enjoy these topics so any help would be appreaciated.
btw sorry for my bad english im from germany.

Because engineering is for those looking for solutions from existing knowledge, while in Physics we find new and better solutions.

Physics gave us electron tubes (or valves), engineering made these smaller and reliable. And it was Physics that gave us transistors, an entirely new solution to the same problems that valves solved, just so much improved.

>>
>>8992102
It is entirely possible they were working on Coanda Effect saucers during the war because Henri Coanda was working for them during the war and after the war the Americans started trying out saucer designs (captured Nazi saucer technology?) As for the antigravity part I don't think it's true because Paperclip wouldn't have bothered kidnapping von Braun if some other Nazi had antigravity tech. Maybe the Nazis did try some esoteric anti-gravity idea at the Die Glocke site but it was bullshit and didn't work.

We all know UFO means alien spacecraft. This is a NASA paper on UFOs therefore it's a NASA paper on alien spacecraft therefore aliens are real.
