Diffusion pumps are freakin' amazing.

she just said "this is just a calming agent, the real anaesthetic comes later". But of course, it was the real anaesthetic and she was just trying to stop me from freaking out at the last moment (which some people do, apparently).

She lied! Just kidding.

I remember well getting put out for my first open heart. It was much faster than you describe.
A pretty nurse had in her hand a small valve connecting a vial to my IV port. She said "Good Night" and gave it a quarter turn. Almost immediately my vision darkened and i went out before i could give a comeback. I still marvel at how fast it was.

Next thing i remember is gradually coming back toward consciousness aware only of searing pain and darkness. My only thought was "When i open my eyes i know there'll be nothing left below my ribcage - I've been bit in two by a shark nothing less could hurt like this .. "
Then i became aware that a machine was doing my breathing for me.
Then i opened my eyes and could see only a jumble of tubes , vision pretty well blocked by a really big one coming out of my mouth.
So i tried wiggling my toes, it felt as if they were still there . Then i remembered where i was .

It is really amazing that they can get us so far down and bring us back.

But google "Bypass Brain" . It's a real phenomenon.

Open heart? I'd be too scared to have something like that. But why did it hurt later? Isn't there a chemical to block pain? If there are chemicals to put us to sleep so fast, why not chemicals to block pain?

I say mine took 5 or 10 minutes, but maybe I was not aware of time and it happened faster. I remember the walls started wobbling, I saw rainbows, confetti, and cute colored cats... then all of a sudden... poof... I can't remember anything else. So I say 5 or 10 minutes, but I'm not so sure anymore. The person that was with me said my eyes were wide open like and the doctor told her it was taking effect while nodding and smiling.

I learn something every day from @dlgoff

I didn't know that steam jet ejectors were a variant. We used them around our condenser. . No moving parts and silent. Wonderful machines.

 

[jim hardy]

Probably . Morphine knocks it down from excruciating to bearable.
I'd rather have bearable pain than none so as to be aware when i do something too strenuous. I saved up my codeine pills for nighttime so i could sleep.

Don't fear a heart bypass if you need one. Quality of life afterward is way better.

Woke up this morning thinking about prairie grass, Big Bluestem .

Lol, I thought it might have been... "Woke up this morning..."

 

[dlgoff]

... and a bit scary that it doesn't always work properly...

Indeed. I've worked in a couple hospitals as a biomedical engineer; being present in surgical suites. I'll never forget the little 8 year old boy getting his tonsils removed that never recovered.

I feel like names at my place have weird names. That goes from streets to towns. They take names from fruits, birds, animals, and common words. For example, there is Lemon Street, Sweet Town, Hummingbird Street, Blueish Town (I think it takes the name from a rare bird with blue tail that flies through the area and probably no one knows the name from so they went with "Bluish"), Mountain Town (guess what... it's a town in a mountain ), Shore Town... and so on.

Rarely you find streets with the name of people. Streets with the names of people happen only at the cities or at the metropolis. I'd like to live in a Metropolis. I think it would be cool.

I was driving to the gym this morning at my usual time of 3:30 am and I noticed that there were far more cars on the road than I normally see. I never see more than 3 or 4 cars in one 5 mile stretch but today I saw close to 20 with lots of them coming out of subdivisions. What could it be? Why were so many people getting up so early in the morning? And then I realized that yesterday was Valentine's Day. Hmmm, I wonder what they were doing until 3 in the morning?

You know those theme parks or whatever they are called? Well, got free tickets for one and in one of these machines that was going really fast and high an unknown girl behind me yelled: "I'm scared!" to which I yelled back: "Don't worry! I'm scared tooo-aaaaaaaah!"

Never again. Those machines give the feel that you are going to be bulleted and slammed against the ground. They accelerate really fast and suddenly change directions for which the momentum gives you the chills and the feeling that you are going to be thrown away like a missile.

Would you not be scared if you got into something similar to:
https://en.wikipedia.org/wiki/File:Oktoberfest_Schaugeschaeft_2007_Richard_Bartz.jpg

I can't increase my mass, but increase my velocity and see how I go like . Sort of made me wonder... what if Earth suddenly stopped rotating? Would we be bulleted away? Just thinking.

 

[fresh_42]

Earth suddenly stopped rotating? Would we be bulleted away? Just thinking.

With known diameter and rotation period, should be easy to calculate.

Never been on one of those machines you linked to, but I've been on quite a variety of others. Yes, sudden changes can be scary.
However, I have developed quite an appreciation for a different kind of ride.
Our family got on a Mummy (1999) themed ride. I liked it because it controlled your sensory inputs in a wide variety of sensory modalities. It had a little open top trolley on rails moving along through a series of encounters (reminiscent of the movie) in an indoor controller environment.
It involved vision (there were scenery props along the side as well as movies projected at certain places along the ride), audio (sounds with and without the videos), inertial changes like you describe due to roller-coaster like movements of the trolley (side to side and sudden drop accelerations). The thing I was most impressed with was when they were showing a scene of the scarab beetles going under the guy's skin, little squirters mounted under the seats sprays some water on the back of your legs (touch sensation), really creepy. I don't remember any bad smells, but that would not have been difficult.

They have the signs " Wet Paint!" . Still, no matter how hard I try, I have no idea how to make paint any wetter.

This is independent of the Brexit. I like the Brexit, because UK had always been merely more than an obstacle. They had special payment conditions, didn't participate in the Schengen agreement and favor an Adam Smith capitalism I don't appreciate. To say it with Monty Python: "What have you lost?"

I have no idea. It's one of these things you pick up during a lifetime and which you don't have any idea about where, when and why. Yet, my list of unintended losses is longer ... You don't need a formal divorce to get ripped

Can I ask you what part of Adam Smith you don't like?

I mean, you don't accept the fact that there are still people that think that Adam Smith theory should still run the world today, or you never appreciated his theory considering that he published it at his time?

An ounce of gold has always had roughly the same value as a fine men's suit. Not so for a twenty dollar bill.

speaking of random thoughts, when I first saw this yesterday, I thought it was going to say:

"An ounce of gold is worth a pound of cure."

[Psinter]

Didn't know smoking cigars was still a thing. It is incredibly rare to see someone where I am from smoke. I thought smoking was a relic of the past. So much that places rarely put signs of No Smoke anymore. It is unnecessary when barely anyone does it. And you know how corporations are. They want to profit, not spend $1 on a plastic sign of "No Smoke" since it will be considered loses for them . I joke, I joke.

If the 3 people that do smoke light one up, people get away from them quickly. When a person told me that where he comes from a lot of people smoke, I was amazed. Because for me that is just so rare. In the last 8 years I have met only 3 people that smoked. I tell you, it is super rare.

Or maybe I'm the rare one and I don't frequent places with people who smoke? Hmmmmmm... *squints eyes*

I really loved to watch documentations of all kind on tv. I found them entertaining. Nice graphics, short comments and outlooks. Usually pleasant voices. And now? What happened to me? All the time I really listen to what the moderator says, one silent bs comment chases the next in my brain. Thanks PF. They are not fun anymore.

You'd think everyone here is depressed or dreadfully anxious over the incessant inner critic, which you enforce and I/we abide by.

Just saw an image of a highway overpass with graffiti on it, some 100+ feet above ground. There was also, at the street level, an empty liquor bottle, a ragged shirt and some underwear. I can't imagine any outing of mine ever ending up in anything like that. I feel like my life is incredibly boring and predictable. Interesting I heard of someone from India in here that chose to return there, because he believes life here is" too un-random".

Mate of mine and I always said it to each other before our exams. Usually in English, though. The sailor's blasphemy ("For what we are about to receive, may the Lord make us truly thankful") was another favourite.

I had a friend who went into his oral topology exam at a professor, who had been known for his conservative opinion. I think he even had a seat in the local city council. His party translates to the GOP in US or the Tories in UK. As he came back and we asked him about his grade, he said "only sufficient". Well, we answered, you must have known everything. As he asked why, we referred to the pin on his jacket with the symbol of the youth organisation of the socialists (aka Democrats in US, Labour in UK).

Yes, sorry, I was trying to show-off the two-three phrases I know in Latin, but "E Pluribus Unum" did not make sense, and, in Trump's days, it is not true any more, and neither is the " Give me your poor, huddled masses..." ( Statue of Lberty). More like: " We got in first, you get the hell out". Can't think of how to translate that to Latin.

My Latin class was sixty years ago..There's GoogleTranslate... but I'm not fluent enough anymore to check them

I have a nice one for you. A variation of Descartes which someone scrabbled on the toilet door. However, I think it is not kids proof.

There's this website " Topology Atlas"http://at.yorku.ca/cgi-bin/bbqa . As if it were Scrabble, I am renaming it " Topology At las(t) " .

Maybe not, but I would think it would intimidate anyone to see that Germans do graffitti in Latin when most here can barely handle English sentences.

"Quidquid latine dictum sit, altum viditur" is about the only one I can rattle off off the top of my head. Also the Ankh-Morpork City Watch motto, "Fabricati Diem, Pvnc", which means "To Protect and Serve", according to Pratchett.

Still, what is this, a Grad school dropout writing graffiti in Latin? Do they also write graffiti about, e.g., attempted solutions to Navier-Stokes?

I read that someone wrote "C'est magnifique, mais ce n'est pas la gare" on the walls of Balliol College Oxford once. "It's magnificent, but it's not the station", a rather clever pun on the French Marshal Bosquet's comment on the Charge of the Light Brigade.

It has what the French would call an " I don't know what" , doesn't it ;) ?

Hey Freshmeiter,
Can you define non-isomorphic Hilbert space structures on the same set/space, say R^n? Just a lead, to not be too "non-random".

 

[fresh_42]

Finitely defined. Whether it's of finite execution time is how fast one can check a single case, because it's competing with our astonishing birth rate. Rabbits? What a bad joke!

I don't know, how about function spaces with different measures for square integrability?

Here's a random thought on screen protectors. Are they even worth it? I don't know if I should get a screen protector for my phone. For the last few years all my experiences with screen protectors have been bad. They lose touch sensitivity. I also noticed it takes more than one year for my phones to get screen scratches without protectors. For which I'm wondering if I should maybe give it another chance.

I don't know how some folks manage to scratch their screens. I heavily use my electronics devices and that has never been a problem for me. Maybe they purposely put grains of sand on their fingers and then use their phones. I also don't understand how they let them fall and pretty much crack it the first time. My cellphones and tablet have fallen a lot, but I've never gotten a cracked screen or a cracked edges. Even when a tornado destroyed my place and my phone spent a little more than 2 days submerged in water and at least 50lb of debris, I managed to salvage it. After drying it for 3 days, it turned on fine, it worked, and there was not a single scratch on the screen. It was not waterproof by the way. It was a cheap Galaxy. It had no case protector, nor screen protector. Yet not a single scratch on the screen. Just a few white pixels, but you have to hold it at an angle to even notice the white pixels. Otherwise it is not noticeable. I am being honest when I say that I don't understand how some folks manage to destroy their phones by a single fall. Mine always seem to be quite resistant despite my heavy use and bad treatment towards them.

So I was thinking about the worthiness of screen protectors.

Wow, tell that story to one of the phone companies, seems like it would make a great commercial -- and sorry to hear that.
How about the absurdity of putting phones in one's back pocket? A small planned "accident" , a quick hand, and the phone is gone. Or phone drops and it is not so easy to tell. Doesn't seem to make sense.
