Does anyone have list of math books listed as pic related for becoming a math major ? I saw it once but forgot to save it.
Thank you

Am I a brainlet for spending most of my free time doing useless shit that won't add anything to my life? Can I be scientist and still spend most of my free time shitposting and playing vidya? How far can I go with this behaviour?
The internet is the worst thing to ever happen to the human race.
>>8548648
I think that's exaggerated
Do what you want, you get 80 years on this planet before you go senile or die, so don't let anyone tell you how to spend them. None of it matters in the end.
Is it really so outrageous to think that years ago there were ENORMOUS trees that all became petrified after a massive flood?
>>8548322
Yes.
>>8548322
>became petrified after a massive flood
How does that work
>>8548334
>The petrifaction process occurs underground, when wood becomes buried under sediment or volcanic ash and is initially preserved due to a lack of oxygen which inhibits aerobic decomposition. Mineral-laden water flowing through the covering material deposits minerals in the plant's cells; as the plant's lignin and cellulose decay, a stone mold forms in its place. The organic matter needs to become petrified before it decomposes completely.

Level: Babby tier
Concepts used: Basic Geometry
Give the area of the section of a circle of radius R created by a line of length L drawn between two points resting on the circle.
>>8548304
I probably have a shitty methodology but here goes.
It looks like the area is progressing linearly.
A(L) = a*L + b
I will assume that 0 < L < 2r
If L = 2R, we have Area(2R) = [math](\pi*r^2)/2[/math]
If L = 0, we have area(0) = 0
So b = 0
So a = [math]\frac{\pi^2}{4R}[/math]
A(l) = [math]\frac{\pi^2}{4R}*l[/math]
Don't you need the angle?
>>8548337
The angle is not a given.
Will this ever be possible? If so, When?
Any ideas to make it happen?
>>8548298
Making a good star wars continuation? Maybe in a few decades and only if M. Bay and JJ Abrahams join forces.
>stopping photons in mid air
Yeah... no.
Yes, it is possible. Its still a long time until they get something like in your pic but 3D holograms exist
>products of oil combustion are water and CO2
What's stopping us from just gathering water and CO2 and transforming those in oil in some sort of reverse chemical reaction?
>>8547685

>>8547685
You spend energy doing it.
>>8547685
It's been possible since forever but the oil companies suppress it
Why do they hate us /sci/? For what reason would they want to torment me so?
You know how you live on Earth? Did you ever consider it might be a living, sentient being that you're negatively affecting by living and reproducing on it? No.
Same thing with a virus and organisms.

Well, people in general.
Did any of you brainlets study geometric measure theory?
I came across varifolds in a text about rough paths and the topic appeared quite interesting. But before I waste my time reading 700 pages of a book, I'd like to know whether this an important subject or rather a niche topic. Is it valuable knowledge or merely some autism game?
Total autism game
I know some people doing GMT. As far as analytical subjects go it's reasonably interesting I guess, and it's certainly not a niche subject. The kind of problems the average person works on just isn't that interesting, though. It's like the subject lacks very much depth, but I guess the same goes for a lot of analytical subjects.
It's boring as fuck. Had to take a class not long ago. Couldn't get my heart into it.
How in the HELL do you even begin designing novel enzymes?
>>8546165
There's a reason people study shit like this their whole lives. This is that reason.
>>8546165
By designing, do you mean de novo creation? If not rational site directed mutagenesis and directed evolution are currently in use to make enzymes better or to give them new functions
>>8546165
The same way you design any complex modifications with a top-to-bottom approach.
You a) experiment with small changes and b) identify reusable modules and recombine them. If you're confident with recombining modules, you start creating modified modules to suit your needs.
Are you smarter than a Nip?
Fuck off

Guys I really need help with this computer science assignment. I don't understand it at all.
In this assignment, you are asked to write a program for an online carpet store to process installation orders. Each order includes the following information: (1) name of the customer, (2) number of rooms, (3) size of each room, type of carpet (premium or standard), and (5) distance for delivery. The charge information on an order is as follows:
The price of a square foot of a premium carpet is $25 and a standard carpet is $10.
A 20% off discount is applied to the total charge (before adding delivery fee) when a customer orders carpet for more than 1000 square feet.
If the distance is 0 (i.e. self-pickup), no delivery fee. Otherwise, it is $2.50 per mile.
Price of installation is $5 per square foot.
In order to reduce the complexity of the program, assume each order contains no more than 5 rooms.
Customers may order different types of carpets for different rooms.
You may use the Rectangle Class as a guide.
Requirements:
Note: All variables should be defined as local variables (i.e., global variables are not allowed to use except of global constants) in the program. Otherwise, half of the points will be taken away from the following steps.
Create and define a CarpetOrder class. The class should include:
[5 points]Attributes (member variables): (1) length of each room, (2) width of each room, (3) type of carpet.
[10 points] Activities (member functions): (1) constructor(s), (2) getters and setters for each attribute, (3) method for calculating the area of a room, (4) method for computing the carpet cost for the room based on the carpet type.
[15 points] In your main function
Prompt the user to enter name. Note: use getline(cin, identifier); statement to read string type input into 'identifier'.
Prompt the user to input number of rooms.
While the input is invalid, keep prompting the user to re-input (integer between 1 and 5). You should create a function to check the validity of the input information.
Prompt the user to enter delivery distance. The delivery distance must be between 0 and 50 miles.
Create an object for each room/space using an array of objects. For example, Room room_list[5]; creates an array of five Room objects.
Prompt the user to enter length, width, and carpet type for each room. While the input is read, use setters to define the length, width, and carpet type of each room.
Compute the total charge for the order. Include a function for computing the total charge (including the carpet cost, installation fee, discount if any, and delivery fee)
Print the order information. Information to be printed: customer name, number of rooms, size of each room, type of carpet, and cost of the carpet for each room.
Print total area, the distance for delivery, amount of discount, total charge (including delivery fee) at the end.
[2 points] For the CarpetOrder class, define a header file (.h file) for class declaration and a .cpp file for member function definitions/implementations.
[3 points] Add sufficient comments and make your program, especially the main function, as concise as possible.
Guidelines for programming assignment:
For your final program please add the following comments to the main function
/*
* Names of classes you defined:
* Date of creation:
* Date of modification:
* Author:
**/
Please comment your code to describe what you are doing. Your creativity is welcome.
Please choose meaningful variable names and avoid the variables such as h1, d1, etc.
You should debug and test your program to make sure your program has no syntax and logical errors. If you have any problem running your code, please document them by comments as well
A sample output:
This program will calculate the cost of carpet installation.
Please enter your name: Ray Smith
Enter the number of rooms: 3
Enter distance for delivery: 30
Enter the length of the first room: 20
Enter the width of the first room: 30
Enter carpet type (p for premium carpet, s for standard carpet): p
Enter the length of the next room: 20
Enter the width of the next room: 40
Enter carpet type (p for premium carpet, s for standard carpet): s
Enter the length of the next room: 10
Enter the width of the next room: 30
Enter carpet type (p for premium carpet, s for standard carpet): s
The following is your order details:
Customer name: Ray Smith
Number of rooms: 3
Delivery distance: 30 miles
Room 1 information: Size: 20x30, Carpet type: Premium, Cost of the carpet: $15000
Room 2 information: Size: 20x40, Carpet type: Standard, Cost of the carpet: $8000
Room 3 information: Size: 10x30, Carpet type: Standard, Cost of the carpet: $3000
Total area: 1700 square feet
Cost of the Carpet: $26000
Cost of installation: $8500
Discount : $5200
Delivery charge: $75
Total amount: $29375
Hey guys, I'm wondering if anyone has ever considered sending Cyborgs to Mars? In all of Elon Musk's talks and other Mars talks, I'm never heard mention of people with metal limbs.
My reasoning is that people with fewer limbs should need less food for sustenance, no? So instead of food, you need batteries?
What are the challenges associated with making a volunteer into as much of a cyborg as medically and technologically possible, and then sending that guy to Mars.
Also, how about funding this volunteer by making a reality show?
Note: I can volunteer, if needed.
>>8550317
OP, do we have cyborgs on earth?
Only cyborgs due to necessity. Not yet cyborgs due to cosmetics.

Where were you when you figured out e was it's own derivative.
mind = blown!!
>>8550101
>value at point x equals the slope in point x equals the area under the curve from -infinity to x
literally why is this allowed
>>8550101
The derivative of e is 0
