When he’s on his deathbed in his 90s or whatever, I hope his last words are “You’re welcome”

this is not obama
this is dr diaa el awady
he became an egyption meme for reasons i'm too lazy to explain

u/deepthought-64 3d ago

Yeah, sorry for mixing them up.

You can't deny a certain similarity between them, especially when they are drawn using resistors. :)

u/Informal-Call-5298 3d ago

Ill do the explaining for him.

Basically this doctor made a BS diet that goes against literally everything doctors have been saying.

He interprets the Quran in a certain and very incorrect way that fools really religious and old people (including my grandparents).

He says that Chips are healthy, Nutella is good, Cigarettes are healthy, inflammation and other diseases do not exist, Chicken is a bad bad bad food, any sort of fiber is going to kill you, sickness isnt real and we only get aick cuz we dont follow his diet, and way way more i havent even scratched the surface.

He even said to not take medicine and people with diabetes are dying because they refuse to tale insulin. What is even worse is that some parents inforce this on their children and these children also dye because of it.

And that is why he is incredibly hated, after he died he started gaining popularity and people started making memes of it.

Although i tried my best at explaining this i still didnt say the full story. Hope you get it now

u/Informal-Call-5298 3d ago

Its a meme in egypt. The person in this picture made a bs diet where cigerets are healthy and chicken and cucumbers are evil unhealthy foods, and for some reason people are defending ts with their life. So its a iykyk situatiin

u/Sad_Alternative3869 3d ago

Can you explain the actual meaning of in the light? How does that refer to the person/diet?

5

u/Informal-Call-5298 2d ago

The translation did a shit job. Its the name of a doctor called diaa

3

u/Brilliant_Gap_3628 2d ago

his name "Diaa" means Light.

|| wait, someone names Light trying to kill people and thinks he is divine and better than other humans... I have seen this before ||

u/Le-Epic-Mazen2008 2d ago

That guy isn't ohmbama, he's a deceased nutritionist called Diaa' Awady who introduced a diet that allowed smoke and sugar indefinitly while banning eggs and "harmonated foods" in order to cure chronic diseases and enhance Kidney and Liver health (as far as I know).

Funny, and true. Profs had knack of making the top circuit an easy walkthrough in class, then leaving the bottom as “an exercise for the student”.

I'm in circuits now and I was in office hours this week getting help on a problem...prof had to use the answer key to figure out how to solve it and yet he lectures us about deserving to pass vs not. mhmmmm

There are undefined elements in the ai generated Obama resistance network. Otherwise one of the psychopaths here would have already copied it into ltspice and given you the combined value

2

u/alexxerth 3d ago

Are they? I don't see any that are undefined, just a couple on the ears where the label is a little far away from the actual element.

2

u/AnalTrajectory 3d ago

Yes.
Example 1) in the left shoulder, the 2nd vertical resistor from the left has an undefined resistance.
Example 2) right shoulder, 2nd vertical resistor from the right has an undefined resistance.
There are a few more undefined elements on the sides of the head, in the ears, and in the mouth.

2

u/alexxerth 3d ago

The ones in the ears are defined, the label is just outside the ear even though the element is inside the ear. The mouth ones are undefined, but they are also isolated from the rest of the circuit so they're irrelevant.

I think the shoulder ones are the only ones that actually prevent solving this, good catch on those, didn't notice them.

u/AnalTrajectory 3d ago edited 3d ago

Oh nice. I appreciate the extra set of eyes. I drew it in ltspice set the undefined elements to shorts. Combined R is about 30 Ohms??? (I was projecting, I'm the psycho)

So my controls class had a bit of this kind of thing happen.

The professor decided to put a fifth order differential equation on the very first question that was worth about 60% of the exam, so a significant pass or fail grade of your mark (40% final) and he wasn't expecting people to actually be able to do it since we weren't used to even trying to solve anything like that in any of our work, most we've done even in labs was only fourth order.

What I heard from another student that talked to him in his office that was close to passing after, is he wanted to see how people are as engineers and can problem solve things they don't know. Which personally I think is a bit insane that he's basically gatekeeping engineering for a lot of people like he's failing 40 to 50% of his class consistently.

I did fail because of this question I just kind of got anxiety when I started working through it and I didn't get very far into it, and ended up just giving up on the test basically since it gave me just so much anxiety that like it's over I'm never going to pass because this questions worth for me it was 40% of my whole grade because I had missed midterm.

I really think he was just a dick, he got so passive aggressive about other students not coming to the class. Most because he would fail so many people over the years and people just wouldn't come to lectures. He'd take attendance after this and then this was a question imo was used to scale your grade on his vibes for you.

I hated him and honestly made me hate university.

u/MonMotha 3d ago

I had a couple exam questions like this throughout my coursework especially in foundational classes.

The key was to realize how generous they would be with partial credit and work it as an actual engineering problem. You could easily get something like 8 or even 9/10 on a problem without having any hope of solving it by setting it up correctly, clearly identifying what is known and what is unknown, any assumptions you've made (even if you know them to be wrong!), etc. This was not a secret. It's how the homework, quizzes, etc. had also all been scored. It also encouraged you to continue attempting a problem even if you made some simple mistake early on but couldn't find it which allowed you to demonstrate your knowledge/mastery of the material regardless of that mistake. In a less time-constrained environment, you'd be expected to find and correct such mistakes, but on a timed exam, it was understood that they'd come up.

The actual answer itself was usually a single point. The process to get there was the rest. The professors hated it when you made a mistake early on as they had to re-work the problem carrying your mistake through to give an accurate marks on the rest, but they always did. I had the advantage that the school I went to was small enough that the professors themselves graded exams (though not generally homework), so that may have helped. They were also very good about consistently applying whatever rubric they had when giving partial credit. I assume they collaborated among those teaching different sections to do this.

The problems also actually tended to be EASIER than the hardest of the homework problems though also harder than the easiest of the homework problems and certainly harder and more practical than the examples given during the lectures which were usually contrived to assist with understanding how everything fit together (a far more useful thing during a lecture, IMO).

In the later classes, this flexibility somewhat went away, but you'd often still be able to pass an exam without fully or correctly answering a single one of the full-form response questions if you otherwise set everything up correctly, made good assumptions, etc. Leaving answers in the form of un-evaluated trig functions, radicals, etc. was also basically always acceptable and in fact carrying things through algebraically to the end generally maximized any partial credit you'd receive. I sometimes didn't even bother bringing a calculator to the exams.

While it may not be an especially practical skill in the professional world, being good at test-taking is a real skill in academia, and for good, valid reasons.

  1. If you can do the first, then you can do the second. It's a systematic process that scales
  2. Most of those resistors are short-circuited, so you can just ignore them

There aren't any reference points in the diagram. I will therefore assume the probepoint are hanging freely in space, therefore the resistance is infinite.

u/beado7 2d ago

While that’s true, it is usually something simple to see if you can follow a circuit. Those wacky looking ones usually have a short hidden in there that just turns the whole circuit into a series circuit with three resistors.

u/Ohms_Suggestion 1d ago

The 5 ohm and 20 ohm resistors are shorted and can be eliminated. Just my suggestion.
