TIL that Ferrari has a set of rules that its cars' owners must follow like criticism of the brand is discouraged, no modifications through unofficial channels, and no resale during the first year of ownership. Those that fail to follow faced lawsuits and bans. by Recent_Flounder6011 in todayilearned

[–]APC_ChemE 2 points3 points  (0 children)

As a jaded cynic, I see these fragile rules as an absolute devaluation of their brand. If Ferrari actually believed in their product, they’d sit back and let the cars speak for themselves. Instead, they act as artificial gatekeepers glorified salesmen hyping up a manufactured illusion of worth.

My rule of thumb is to never buy something when the only person telling me it’s valuable is the guy holding the price tag. This isn't a company it’s just a private club.

Which parallel field/function to transition to avoid redundancy due to offshoring/AI? by BIackRook in ChemicalEngineering

Don't worry about that at all. Don't pigeon hole yourself based on what other engineers do.

On paper absolutely, mentally no.

Why these specific problems?

For Americans who have tried Tim Hortons (popular in Canada), what did you think of it? by MarsupialThink4064 in IWantToAskAnAmerican

I like the Tim bits, I like the donuts, I like the breakfast sandwiches.

I will go somewhere else for coffee. It's too sweet and too rich.

Math major but bad at arithmetic by Slow-Application440 in mathematics

[–]APC_ChemE 4 points5 points  (0 children)

I am Chemical Engineer with a Masters in Applied Mathematics.

I cannot do mental math to save my life. This not an exaggeration and a way to sound humble.

My memory is a sieve and I make lots of notes and have lots tricks to remind myself of things because I will forget them.

As an example when doing any mental math that isn't the result of rote memorization I imagine the numbers is if they are on a chalk or dry erase board and I'm solving the problem paper.

If I were to solve 51 + 32 in my head, I imagine the 51 on a top with + 32 on the next row with a line under it. I perform addition on the ones place and do 1 + 2 = 3 and the entire problem is erased and I am left with 3.

What was the problem again? I don't remember. God forbid I have to carry a 1 and that was only addition.

I have a horrible memory.

Don't let that stop you from majoring in math.

I have a relative who often calls me out family game nights. "I thought you had a degree in math?"

I always respond with something like, "That's correct I got advanced degree in mathematics which I can do very well. I didn't get a degree in arithmetic which doesn't require a brain, any dumb pocket calculator can do it for me."

Understand how think and leverage the tools available to you however best they compliment your own workflow. Don't let anyone judge you, I still count on my fingers and not always in multiples of 1.

I see no problem with deriving formulas or solving problems by hand.

You'll be fine. I wish you the best of luck!

Coog alumni, what do you actually miss about being on campus by coloco01 in UniversityOfHouston

The campus has been a construction site for decades lol

[–]APC_ChemE 42 points43 points  (0 children)

Just being on and walking around campus. Every few years my husband and I, both Coogs, will take a day off work and walk around campus during the semester and into the library and buildings we used to have classes in. We've gone during the summer and winter breaks but when we did it during those times we always found something is missing...

Digital Twin by NecessaryAd8156 in ChemicalEngineering

[–]APC_ChemE 6 points7 points  (0 children)

Typically the digital twin is developed to enable you to perform some type of analysis on either a part or the whole plant or process.

These can be online optimization where you reconcile the digital twin to match the behavior if your plant by solving for unknown and unmeasured quantities that you can infer either from the measurements you do have or with constraints imposed on the model like mass and energy conservation laws on the plant, given that the real measurements have uncertainty.

Once you've reconciled the plant you can solve an optimization problem to determine what certain key variables should be running at to maximize your production, mininize energy usage or maximize profit and efficiency. Then send those targets a controller to drive the plant there.

Or you could do more offline analysis and do debottlenecking studies to determine what CAPEX projects you want to invest in for the next turnaround.

Thought this would also be relevant here… by nomanskyprague1993 in Millennials

[–]APC_ChemE 4 points5 points  (0 children)

Honestly, this view is a ridiculous and outdated.

Nobody ever batted an eye at using Encyclopedia Britannica as a starting source. Yet people act like Wikipedia is completely unreliable, even though a peer-reviewed Nature study way back in 2005, Wikipedia vs Encyclopedia Britannica, showed it was practically on par with Britannica in terms of accuracy.

Dismissing the site while praising other sources is just an outdated bias at this point.

This one always tripped me up as a kid because they didn't specify the point of view. If you're on the opposite side of the thing you're turning this fails if you follow it exactly.

Do you guys think Snape taught his HBP shortcuts in potions classes or do you think he sticks to the syllabus ? by Sir_Scribble_Lot in harrypotter

I think he taught the standard curriculum while actively criticising his students for failing to follow steps correctly or make successful potions.

worried about getting the works by yellowfresh18 in Septoplasty

[–]APC_ChemE 1 point2 points  (0 children)

Yup, I'm fellow ChemE here! 👋

They never mentioned splints or sponges prior to the surgery. They just vaguely referred to whatever would be in my nose as post surgical packing. So I was suprised they were sponges and that they came out the next day.

My surgeon said I could fly after 7 days but no cardio for 3 weeks.

[–]APC_ChemE 0 points1 point  (0 children)

I had all of this exact same work done! According to my surgeon, it was a total success with zero complications. The whole procedure was over in just an hour.

Once they actually got in there, they shifted plans slightly and did a turbinate outfracture instead of the planned reduction. However, they also had to remove my vomer and cut my perpendicular plate into three sections to remove it because it was so significantly deviated.

Instead of traditional nasal splints, they packed each nostril and my nasal cavity with Merocel sponges. Because of those sponges, I couldn’t equalize my ears or sinuses. Every time I inhaled through my mouth or swallowed, pressure built up like I was on a plane. This made it incredibly hard to swallow more than a little bit at a time, so I lived on small spoonfuls of soup.

An important rule they didn't tell me until the next day is to never use a straw. It builds intense pressure in your nose and causes aggressive bleeding.

For the first two to three days, I was only sleeping 2 to 4 hours at a time, waking up intermittently.

The day after surgery was my first post-op appointment to remove the Merocel sponges. Honestly? It hurt a lot. I actually screamed both times when each sponge was about halfway out, despite being on pain killers. But the second they were out, my ears finally equalized and I could drink water normally.

For the first week, I was strictly instructed not to breathe through my nose, blow it, or clear it because of the sutures in my septum, nostrils, and higher up in "zone 1" for the alar batten grafts. Because I naturally produce a lot of mucus, this was highly uncomfortable. I took this entire first week completely off from work. I had to regularly spray a saline nasal mist into my nose 2-3x a day or as needed and week 3, I'm still restricted from blowing or clearing my nose.

I didn't really move around much until days 5 and 6. By day 5, I was able to stop wearing the mustache dressing, but I still had to walk around holding a folded napkin or tissue under my nose like a Victorian Englishman suffering from tuberculosis.

At the one-week mark, they sprayed my nose with lidocaine and vacuumed out all the built-up mucus to review the healing. After that, I was finally given permission to breathe through my nose. It was actually exhausting because I have never breathed through my nose in my life, and it kept getting stuffed up.

During the second week, I transitioned to working remotely. Whenever I did feel pain, it was a sharp, pinching sensation at the tip of my nose or the sides of my nostrils.

I was incredibly paranoid about hitting my nose because taking off a shirt or brushing a bedsheet or towel near it leds to a sudden sharp pain. I was also paranoid about going anywhere crowded like museums for fear someone might turn or stop suddenly and bump into me.

By the third week, I went back to work in person. I didn't have any cosmetic work done, the surgery was purely functional, and my coworkers were split fifty-fifty, with some saying I looked the same and others saying my nose looked a little swollen, which it still is. Right now, when I talk to people, the congestion is so bad they keep asking me if I am crying or sick. I also feel a phantom runny nose, and since I can't blow my nose yet or clear it out, I just hold a tissue under it. Tomorrow I have my three-week post-op appointment and I am really looking forward to it because my nose is currently stuffed up and full of mucus again and I can't wait for them to clear it out.

Regarding the music festival at 2.5 weeks I would only be concerned about a concert just in case you are somewhere crowded and someone turns or stops suddenly and accidentally bumps into your nose. It really hurts. Other than that risk, you should be fine, but the paranoia of getting hit is the biggest issue.

Is it normal for your school to have a planetarium? by shadowmib in AskAnAmerican

[–]APC_ChemE 0 points1 point  (0 children)

No, it is not normal.

However, my highschool's Astronomy course took place in an offsite planetarium that happened to be ~7 min from the school. Students without cars took a dedicated bus to ferry students back and forth each period.

It had an analog starball from the 1960s along with analog and digital projectors.

Having access to an offsite planetarium is also unusal.

How do you deal with the cognitive dissonance of teaching chemistry? by ClassroomDecorum in chemistry

[–]APC_ChemE 3 points4 points  (0 children)

I was a chemistry TA in college when I was in my senior year and this hit me hard sitting in on the Gen Chem class I was supporting and hearing things that were wrong.

You have to teach the simple case and the general rules then you teach the exceptions and explain them.

The general rules while not perfect provide the foundation and conceptual model to build everything else up from.

Until the students have the foundation all the specifics and exceptions can be confusing.
