Tell Me Something I Don't Know

[scifes]

A thermodynamics professor had written a home exam for his graduate students. It had only onequestion:

"Is Hell exothermic (gives off heat) or endothermic (absorbs heat)?
Support your answer with a proof."

Most of the students wrote proofs of their beliefs using Boyle's Law (gas cools off when it expandsand heats up when it is compressed) or some variant.

One student, however, wrote the following:

"First, we need to know how the mass of Hell is changing in time. So, we need to know the rate thatsouls are moving into Hell and the rate they are leaving. I think that we can safely assume that once
a soul gets to Hell, it will not leave. Therefore, no souls are leaving.
As for how many souls are entering Hell, let's look at the different religions that exist in the worldtoday. Some of these religions state that if you are not a member of their religion, you will go to Hell. Since there are more than one of these religions and since people do not belong to more thanone religion, we can project that all people and all souls go to Hell; with birth and death rates asthey are, we can expect the number of souls in Hell to increase exponentially.

Now, we look at the rate of change of the volume in Hell because Boyle's Law states that in orderfor the temperature and pressure in Hell to stay the same, the volume of Hell has to expand as soulsare added, this gives two possibilities:

1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then thetemperature and pressure in Hell will increase until all Hell breaks loose.

2. Of course, if Hell is expanding at a rate faster than the increase of souls in Hell, then thetemperature and pressure will drop until Hell freezes over.


So which is it? If we accept the postulate given to me by Ms. Therese Banyan during my freshmanyear, 'That it will be a cold night in Hell before I sleep with you,' and take into account the fact thatI still have not succeeded in having sexual relations with her, then 2 cannot betrue, and so Hell is exothermic."

This student got the only A.

lol..
got one similar..told to us by a teacher when he had a philosephy exam..he and his fellow students(back then) really hated the subject and more the teacher..they studied the books as hard as they could..and when the exam day came and he handed the papers..there was only one question....one word..

"why?"..

the students kept looking at each other searching for clues..before they all started copying each and every therom and piece of information they can remember into the paper...they all got messed up marks..except for one who got an A..

when they saw his paper..it was blank..except for one word..


"what?"

one of the explenations for de-ja-vu is that it's when an event get's registered in the subconcsience only at first..then replayed into the conscience..making us feel as we've experienced that certain event before..

 

[scifes]

the image we see of the planet and the cosmos around us are actually many million years old..depending on the distance....the interesting part is that when scientists develop telescopes with stronger magnification capabalities..it is like they are creating time machines..if by the naked eye you see the state of a star 500million years later..then with a certain telescope it'll be like you've jumped 200 million years ahead and you're seeing what's happening 300 years ago..a yet even stronger telescope might be able to jump 400 million years and make you see only 100 million years late..and so on..

it also means that whatever we see with our eyes no matter how close it is, is as old as the time it takes photons to reach our eyes from the object..so there is no such thing as "real-time" observation..

when amazon ants invade another ant colony..they enslave the conquored ants to do their bidding!


when bald eagles mate..they lock talons and start a virtical dive to the ground..if they don't finish their business quickly..they end up crashing (or splattering) on the ground..it's like a do or die thing..

the eagles mating through the cartweel display turned out fake btw..they do lock talons and do aerobatics..but the mating part is untrue..(opposite to what many people think)

The greatest number of children born to a single woman was 69 (16 sets of twins, 7 sets of triplets and 4 sets of quadruplets). The woman was the wife of Fedor Vassilet.

Light, Heat, and God

Darkness is nothing but a absence of light. You can measure intensity of the light to infinity but can you do the same for darkness? Cold is nothing but absence of heat. Heat can be measured to infinity but cold maintains a steady value at a certain degree. Absolute zero (-460 F) is the total absence of heat; and all matter becomes inert and incapable of reaction at that temperature. It was proclaimed that Albert Einstein said: "Evil does not exist, or at least it does not exist unto itself. Evil is simply the absence of God. It is just like darkness and cold, a word that man has created to describe the absence of God. God did not create evil. Evil is the result of what happens when man does not have God's love present in his heart. It's like the cold that comes when there is no heat, or the darkness that comes when there is no light." There is no proof that Einstein said this and there is no proof that he didn't. However, based on constructive thinking there is no reason to suppose that Einstein was part of this "fictive" story.

energy itself is just em (light) and since it is IMPOSSIBLE to created a perfect vacuum between 2 points of mass, then NO WHERE in existence is without light.

You can measure intensity of the light to infinity but can you do the same for darkness? Cold is nothing but absence of heat.

the 'heat' of mass is simply the em (light) upon that mass (all cases)

BEC (Bose einstein condensate) is just mass isolated with the minimal amount of 'energy upon mass' .......... the experiment is created by man

Heat can be measured to infinity but cold maintains a steady value at a certain degree. Absolute zero (-460 F) is the total absence of heat; and all matter becomes inert and incapable of reaction at that temperature.

as suggested but not true as entangled mass in rubidium shares properties the scientific community is just now beginning to observe (the potential between mass caused by the energy upon the mass)

soon people will find the energy is more important than the mass itself as no mass does anything without energy causing it; all cases

i left out the God theory stuff; wrong section on the forum

wow..very interesting..

why is it impossible to create perfect vacuum between two points of mass?
what do you mean by "two points of mass"?


-very practical piece of information..half of the body's heat exchange happens through the head.

Then either he didn't read very much, was a little bit near sighted, or was a one in a million exception to the rule. I often hear tales of these people who never needed glasses until they were seventy. But I've never examined anyone 50 years or older who didn't need bifocals.

He must be the exception then.
Are you saying you get bad eyes from reading ?

 

[Bishadi]

wow..very interesting..

now if the Big E, believed God 'is the garden' now reread the quote you posted. (most just don't see that he is not talking about a guy on a thrown, he is maintaining the politics of beliefs while keeping the truth on his tongue)

why is it impossible to create perfect vacuum between two points of mass?
what do you mean by "two points of mass"?

a perfect vacuum has no energy. And enclosed 'anything' will always have association to all other sides.

eg.... if you could go to the edge of the universe and shine a flashlight outward; would you see anything? The postulate is, no energy can exchange without 2 points of mass.

There is never ever a perfect vacuum between points A-B as neither can be divided without the other to compare/measure. (what is gravity between mass? A potential exists between associated mass. (it's a spooky FACT)

-very practical piece of information..half of the body's heat exchange happens through the head.

i thought most intake came in the mouth.

An anology could be to observe what happens after a single wavelength is imposed to the water molecule within food by a microwave oven. One wavelength causes 'heat' to be observed by the surrounding material (food).


kind of weird (to standard thinking); but heat is not a property of energy, (note the simplicity of how temperature is measured).......... the energy itself is the em! Each portion of mass affected exhibits its own motion/momentum based on the wavelength that is exposed to it.


the microwave fires just one wavelength but the mass converts it

the specimen is the em, not the heat

Hi there! I'm pretty new to these forums, so I apologize if this sort of thing isn't allowed here.

I recently launched a site whose goal is to allow people to share the knowledge they've gained through their experiences. Most posts are a couple sentences long, and they usually describe some phenomenon, misconception, fallacy, etymology, or otherwise rare but interesting piece of knowledge. We created the site in order to help people who are interested in learning new things but may not have special access to academic journals, or may not want to bother reading through them or Wikipedia articles to find the interesting stuff.

So, I invite you guys to share that sort of stuff here, and I'll post them on the site (unless you don't want me to). I post this request here because I figure a lot of you know some really cool stuff that most people (who know little about your particular field of study) aren't aware of. If you want to visit the website itself, the URL is: sharetolearn.net

So anyway... go ahead, tell me something I don't know!

Sean

all possibilities of everything now and in the future

My wife is 65 and only uses (off-the-rack) reading glasses. I don't know if her distance vision is perfect, but no one has prescribed correction for it. I, on the other hand, have had trifocals for about fifteen years.

US spends more on it militray than the next 14 largest spenders:

Here are the numbers in billions of dollars annually (based on 2007 data):
USA 607
China 84.9*
France 65.7
Great Britian 65.3
Russia 58.6*
Germany 46.8
Japan 46.3
Italy 40.6
Saudi Arabia 38.2 (but that includes the domestic police.)
India 30.0
Brazil 23.3
Canada 19.3
Spain 19.2
Australia 18.4

For example my English "research" was "Pesquisa" in Portuguese and I do not know that word in Swedish. Also I had to guess at the word order.

Also note paper only listed the top 15 spenders. Probably US spends more on its armed forces than all the rest of the world's total !!!

These Mother F....ers are costly. US maintains 12 of them, I think, but China has none.*

Do you think we need them all? In an era where the real danger is a few guys willing to die in the explosion of their bomb belts or by spreading some very deadly germs in a few resturants, and train stations etc. IMHO, one CV per ocean is enough (plus one in US port - Sailors on leave.) - The savings is what the US economy needs to be more secure.
--------------
*During the peak of the "cold war" the USSR built one tiny CV with front part of the deck turned up, like a ski jump, so planes had further to fall before hitting the sea. (Compensation for the short take-off deck.) I am not sure but think it stayed in the Black Sea with only one or two brief excursions into the Med to establish the right to go there. I think the planes had to land on land, so this is another reason why the CV stayed close to "the mother land."

The USSR was never trying to rule the world with their militray power - only defend "the mother land" from their feared US agression.
