It’s a tough course but damn it makes me feel so stupid
BrutalMine is most likely sub 90
Yes. It requires the memorisation of complex polymers, their functional groups and their chemical reactions. And topics like IUPAC nomenclature and NMR are hard.
Brutal aren't curries smart in the West like ricemen?
I think currys are smart. They are highly paid and educated in the west but that IQ chart shows that the average IQ for currys is 85. So idk what is happening
That was how much I studied the week before, ive literally been practicing o Chem questions/ watching videos the day class started every single day since school started.
Aha. Okay then I've no idea man. I've never fully studied and not gotten 9 or 10 out of 10 in the subject.
The exam came and I felt humiliated. It’s like I froze/broke down. It took me 20 mins to complete the first question so I knew it was over

Computers utilize binary sequences to store data. Each bit represents a specific instruction to be manipulated by components of the CPU. This is accomplished by utilizing "0" and "1" to represent separate voltage states of a given segment of the hardware. "0" refers to low-voltage, and "1" refers to high-voltage. Thus, imagine a sequence such as "01010101" as merely representing the computer sequentially reversing the voltage states of various signals within hardware gates. Each gate represents the basic logical operations of AND, OR, NOT, XOR. Perhaps this will interest fellow users? |

I suppose that I was somewhat confused on the type of data you intended to represent with the bits, although I now presume that you intend to use Unicode/ASCII characters. Given the fact that bits/bytes merely represent voltage allocation on the hardware level, it seems rather inappropriate to use the term "code" for this purpose. |
I've recently been preparing for a bit of PCB design. I had little problem designing circuits in high school, though I can't verbalize at the moment so I can't perform calculations.

| ParadigmaticAnon Join Date: 2016-01-25 Post Count: 182 | #183519765Saturday, February 13, 2016 12:37 PM CST I have developed another explanation for the users on the sub-section. Suppose that we a machine containing six buttons. Each button can be successively activated/deactivated using a sequence of instructions. Each "button press" will reverse the button's current state. We can express this as a binary sequence of six bits. This will be our representation: 000111 In the above sequence for our machine, the first three buttons are deactivated. The last remaining three buttons are active. Naturally, since we are working directly with base-two, we can utilize logical operations to modify the behavior of the individual bits. Let us define a function "P", which will represent each unique button press. Imagine that function "P" accepts an input "positional value", and signals a state change to the bit of that position. This would be our notation to use the sequence(Assuming that lowercase "p" refers to the position within the address and uppercase "B" refers to the actual memory address itself): P(p) = ~B[p] The "~"(Or logical NOT) operator merely reverses the numerical value of the bit found. In non base-two context, this would reverse "true" to false, and "false" to true. Since base-two has only two valid digits, 0 and/or 1, this operator will likewise reverse 0 to 1 and 1 to 0. Since our machine has six button, the function will need to be executed exactly six times to affect every digit. Given that our original sequence was "000111", this is how it would be altered: P(1) = 1 P(2) = 1 P(3) = 1 P(4) = 0 P(5) = 0 P(6) = 0 Altogether, the new button sequence would be "111000." Notice how the values of both sets of halves of the button sequence was swapped. Consequently, the first three buttons are activated. The last remaining three buttons are not. |

I heard organic chemistry is the hardest major in existence. Don't beat yourself up over having bad grades in it.I felt like I was smart, did well in school, doing well in college then organic chemistry came my way. Holy shit I feel like my iq is 50. The exam I took destroyed me completely and I know I failed FUCK. I studied soo much for it, at least 30-40 hours and if I get an F on that it confirms I’m low iq. Im so pissed
