Cryogenics.

[Adi87]

Does anybody have any experience with this topic?

I have to write a 100 page paper on this...
I also have to prepare for a three-hour seminar which describes the process and its finer points...
I have to do this before October end.
The other two topics which I can choose are satellites and i-phone... but those two are very popular and I don't want to be repetitive.
I'm fucking scared of this, Can anyone please help?

Sorry, but I think you have to be dead to experience this.

 

[Adi87]

Sorry, but I think you have to be dead to experience this.

Maybe I will be after I fail...
I wont go through into the next year if I fail this.

Watch the sci fi channel, it's bound to crop up eventually

Erm, all cheek aside I really don't know where you'd get this info from, I'll wish you lots of luck and send you happy studying vibes, though.

I predict, if you pursue this theme/topic, that you have a delightful intellectual journey ahead of you.

Several things come to mind, one, a species of frog that, in frigid regions, goes through being frozen solid and then 'naturally' revives when the environment warms.

Understanding how this occurs in nature, without damaging cellular structure, is a matter of research, I am sure you can search and find it.

There is also the aspect of frozen sperm, a long time practice that is beneficial to man, also interesting.

There are also, 'quirks of nature', like Cicada's that emerge only every seventeen years or something, and other frogs that hibernate through drought periods in Africa, sometimes lasting years, but, add water and 'voila!' they live again.

Science fiction writers have long written about cryogenics as a means of preserving humans on a ten thousand year journey to the stars.

There are an unknown number of people, at this moment, who, for one reason or another, terminal disease, curiosity about the future, who have been frozen and maintained in laboratories all over the world.

As with most all research, something fruitful may indeed emerge from research in the field.

As I said...with an open mind, you will love what you discover.

It may even challenge your spiritual values....should man play god with science?

bon appetit'!

Ok...

First explain what class this is...

then please explain why you have two simple subject sand one blow your mind subject? I don't understand why you have 3 subject to write about so very far apart in topic o.0;;;

Cryogenics is not that huge of an issue to research unless you're dealing with the freezing of humans. Cryogenics itself is a branch of physics that studies making stuff really fucking cold.

We build cryogenic eighteen wheeler tankers where I work and they're used for the storage and transportation of things like liquid nitrogen, oxygen, and argon (all of which have to be kept at extremely low temperatures).

I can offer you what little I know but I don't actually install the piping systems for it, I just install the lights.

This is my favorite website for things I need to learn from the fundamentals up: How Stuff Works-
Cryonics

That link is for the introduction, but if you go to the main HowStuffWorks.com homepage and write 'cryogenics' into the search field, you'll find all kinds of other links with facts that may help your understanding. It's nice to have scientific facts put into terms that non-scientists can understand.

Good luck.

I'd enjoy helping you, but I can only help. Unless you are willing to pay too much for me to write it for you.

Suspended animation and human cryogenics from what I vaguely know (from sci-fi mostly) aren't necessarily the same thing. Not that anyone mentioned suss-an.

As Lee pointed out cryogenics isn't always about living things, but when it is, as far as I'm aware it's not about freezing things, that's easy, it's about keeping things alive whilst 'frozen'

The biggest problem is that most biological things are made of water with a few other ingredients thrown in and it's the water that causes the problem. When water freezes two things occur. One is that it reaches maximum density at 4 degrees (I think) which is why ice forms on top of water first because of the second thing. After it reaches maximum density it begins to expand as the temperature lowers further and therefore becomes lighter. Which is why ice cubes and icebergs tend to float. (now some physicist here is going to deny all this and give the real reasons. probably Zoot)

So when cells freeze they have a tendency to burst. So very quick freezing is called for. But the problem here is that very quick freezing (from the outside) is extremely difficult to achieve uniformly, being as how your body will let everything freeze, toes, fingers, nose, eyes before it will let the core freeze.

Now we come to the science fictional part which says that actual freezing won't work because to re-animate there needs to be a slight glimmer of activity. Which is also where suspended-animation comes in. It's not really suspended animation. When something is suspended it stops. If your brain stops there isn't (as far as I know) any way to kick-start it again. Unlike the heart which can be kick started. (performing chest compressions won't restart a stopped heart I'm told. Chest compression is performed to circulate blood until they get the equipment there).

Which all means that freezing to a standstill won't work. Freezing dead people is a pointless procedure. although freezing less than 4-minutes dead, people may have a slight value if they come up with some way of freezing within 3 minutes.

Take all of the above as either gospel or fabrication. It's all guesswork on my part.

Okay... First of all thank you guys for giving me a very good jumpstart...

EL: Thanks.

Jamison: Thank you for the Alcor site, but it didn't help me a lot. I do appreciate your effort and it gave me a good intro.

Chant: Thank you for going through the trouble.

Amicus: I know I'll discover a lot during my research, that was the main reason I chose this topic.

Galaxygoddess: I'm in my second year of Engineering in Computer science...
and I still have two more years after this.
The other two subjects might sound very simple, but that is if I have to only write theory on them. What I have to do on any of those subjects is

1. Write the theory.
2. Figure out the basic working.
3. Draw the main circuitry of the devices most commonly used including the IC's that are used.
4. Write an algorithm of the digital devices used, obviously using the 'gates'
5. Write the main programming of the whole thing.

the other two are not so simple if you think of them now...
I chose cryogenics because since it is a whole branch of physics I can afford to overlook some aspects while going into a good amount of detail into another.

The three topics are far apart because each one tests your knowledge in a different manner...
for example, for an i-phone the circuitry will be given more importance whereas in case of satellites it is the working.

Lee: Yes, and I'm very thankful for that since I have to write about cryogenics in general and not just the human cryogenics.

lucky: Thanks for the site and the luck.

Leigh: I'll be sure to pm you in case I need help.

Gauche: I was thinking of the exact same point for an argument. Thank you.

jayce: That didn't help, but thank you for the effort.

If you come across any site that offers more detail, do PM me.

And thank you again, everyone.
I'll be keeping you informed on my progress.
