Effects of temperature on Computers


Effects of temperature on Computers

How devastating are extreme temperatures on computers? If a computer were exposed to temperatures near zero degrees, would there be an effect on its internal parts (i.e. Motherboard, hard drive, etc.)

Computers generate lots of heat and are also very sensitive to humidity. Generally computer rooms are kept air conditioned in the low 60s.  Extremes of any temperature are not friendly to any type of circuitry. Extreme cold could make circuits brittle and prone to cracking.

Computers (and electronics equipment in general) are much more tolerant of cold than heat. They may be able to deal with zero degrees. Though as was pointed out above,  the components would be more fragile and susceptible to cracking. The main problem would be condensation. If the computer were not designed with that environment in mind you would most likely encounter some problems. Some such as computer modules in cars and military computers do quite well in the cold. I wouldn’t expose my laptop to zero degrees and turn it on.

Douglas Adams Quotes

Douglas_adams_portraitDouglas Noel Adams (11 March 1952 – 11 May 2001) was an English writer, humorist, and dramatist. He is best known as the author of The Hitchhiker’s Guide to the Galaxy, which started life in 1978 as a BBC radio comedy before developing into a “trilogy” of five books that sold more than 15 million copies in his lifetime, a television series, several stage plays, comics, a computer game, and in 2005 a feature film.

• I’m always very sympathetic when I hear people complaining that all they ever get on television or radio chat shows is authors honking on about their latest book. It does, on the other hand, get us out of the house and spare our families the trial of hearing us honking on about our latest book.

• All opinions are not equal. Some are a very great deal more robust, sophisticated and well supported in logic and argument than others.

• Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you’re thirty-five is against the natural order of things.

• We are stuck with technology when what we really want is just stuff that works.

• Anything that happens, happens. Anything that, in happening, causes something else to happen, causes something else to happen. Anything that, in happening, causes itself to happen again, happens again. It doesn’t necessarily do it in chronological order, though.

• Solutions nearly always come from the direction you least expect, which means there’s no point trying to look in that direction because it won’t be coming from there.

• I think a nerd is a person who uses the telephone to talk to other people about telephones. And a computer nerd therefore is somebody who uses a computer in order to use a computer.

• Imagine a puddle waking up one morning and thinking, “This is an interesting world I find myself in — an interesting hole I find myself in — fits me rather neatly, doesn’t it? In fact it fits me staggeringly well, must have been made to have me in it!” This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, it’s still frantically hanging on to the notion that everything’s going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for. We all know that at some point in the future the Universe will come to an end and at some other point, considerably in advance from that but still not immediately pressing, the sun will explode. We feel there’s plenty of time to worry about that, but on the other hand that’s a very dangerous thing to say.

• A learning experience is one of those things that say, “You know that thing you just did? Don’t do that.”

• We don’t have to save the world. The world is big enough to look after itself. What we have to be concerned about is whether or not the world we live in will be capable of sustaining us in it.

• If you try and take a cat apart to see how it works, the first thing you have on your hands is a nonworking cat. Life is a level of complexity that almost lies outside our vision; it is so far beyond anything we have any means of understanding that we just think of it as a different class of object, a different class of matter; ‘life’, something that had a mysterious essence about it, was God given, and that’s the only explanation we had. The bombshell comes in 1859 when Darwin publishes On the Origin of Species. It takes a long time before we really get to grips with this and begin to understand it, because not only does it seem incredible and thoroughly demeaning to us, but it’s yet another shock to our system to discover that not only are we not the center of the Universe and we’re not made by anything, but we started out as some kind of slime and got to where we are via being a monkey. It just doesn’t read well.

• Time is an illusion. Lunchtime doubly so.

• The world is a thing of utter inordinate complexity and richness and strangeness that is absolutely awesome. I mean the idea that such complexity can arise not only out of such simplicity, but probably absolutely out of nothing, is the most fabulous extraordinary idea. And once you get some kind of inkling of how that might have happened, it’s just wonderful. And … the opportunity to spend 70 or 80 years of your life in such a universe is time well spent as far as I am concerned.

• A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

• One of the major difficulties Trillian experienced in her relationship with Zaphod was learning to distinguish between him pretending to be stupid just to get people off their guard, pretending to be stupid because he couldn’t be bothered to think and wanted someone else to do it for him, pretending to be outrageously stupid to hide the fact that he actually didn’t understand what was going on, and really being genuinely stupid.

• “Sir Isaac Newton, renowned inventor of the milled-edge coin and the catflap!”
“The what?” said Richard.
“The catflap! A device of the utmost cunning, perspicuity and invention. It is a door within a door, you see, a …”
“Yes,” said Richard, “there was also the small matter of gravity.”
“Gravity,” said Dirk with a slightly dismissed shrug, “yes, there was that as well, I suppose. Though that, of course, was merely a discovery. It was there to be discovered.” …
“You see?” he said dropping his cigarette butt, “They even keep it on at weekends. Someone was bound to notice sooner or later. But the catflap … ah, there is a very different matter. Invention, pure creative invention. It is a door within a door, you see.”

• It can hardly be a coincidence that no language on earth has ever produced the expression “As pretty as an airport.” Airports are ugly. Some are very ugly. Some attain a degree of ugliness that can only be the result of a special effort. This ugliness arises because airports are full of people who are tired, cross, and have just discovered that their luggage has landed in Murmansk (Murmansk airport is the only exception of this otherwise infallible rule), and architects have on the whole tried to reflect this in their designs.

• The impossible often has a kind of integrity to it which the merely improbable lacks.

• She passed the time quietly in a world of her own in which she was surrounded as far as the eye could see with old cabin trunks full of past memories in which she rummaged with great curiosity, and sometimes bewilderment. Or, at least, about a tenth of the cabin trunks were full of vivid, and often painful or uncomfortable memories of her past life; the other nine-tenths were full of penguins, which surprised her. Insofar as she recognized at all that she was dreaming, she realized that she must be exploring her own subconscious mind. She had heard it said that humans are supposed only to use about a tenth of their brains, and that no one was very clear what the other nine-tenths were for, but she had certainly never heard it suggested that they were used for storing penguins.

• The chances of finding out what’s really going on in the universe are so remote, the only thing to do is hang the sense of it and keep yourself occupied.

• Generally, old media don’t die. They just have to grow old gracefully. Guess what, we still have stone masons. They haven’t been the primary purveyors of the written word for a while now of course, but they still have a role because you wouldn’t want a TV screen on your headstone.

• Any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still know where his towel is, is clearly a man to be reckoned with.

• The first non-absolute number is the number of people for whom the table is reserved. This will vary during the course of the first three telephone calls to the restaurant, and then bear no apparent relation to the number of people who actually turn up…
The second non-absolute number is the given time of arrival, which is now known to be one of those most bizarre of mathematical concepts, a recipriversexlusion, a number whose existence can only be defined as being anything other than itself. In other words, the given time of arrival is the one moment of time at which it is impossible that any member of the party will arrive.

• There is an art, it says, or rather, a knack to flying. The knack lies in learning how to throw yourself at the ground and miss. … Clearly, it is this second part, the missing, which presents the difficulties.

• If we think that the world is here for us we will continue to destroy it the way we have been destroying it, because we think we can do no harm.

And finally,

• Let us think the unthinkable, let us do the undo-able, let us prepare to grapple with the ineffable itself, and see if we may not eff it after all.
