Submission + - Hell explained by a chemistry student. (entensity.net) 1

Sniper223 writes: "Hell Explained By Chemistry Student.

The following is an actual question given on a University of Washington chemistry mid term.
The answer by one student was so "profound" that the professor shared it with colleagues, via the Internet, which is, of course, why we now have the pleasure of enjoying it as well:
Bonus Question: Is Hell exothermic (gives off heat) or endothermic (absorbs heat)?

Most of the students wrote proofs of their beliefs using Boyle's Law (gas cools when it expands and heats 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 at which souls are moving into Hell and the rate at which 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 world today.

Most of these religions state that if you are not a member of their religion, you will go to Hell. Since there is more than one of these religions and since people do not belong to more than one religion, we can project that all souls go to Hell. With birth and death rates as they 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 order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand proportionately as souls are added.

This gives two possibilities:
1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell breaks loose.

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

So which is it?

If we accept the postulate given to me by Teresa during my Freshman year that, "It will be a cold day in Hell before I sleep with you," and take into account the fact that I slept with her last night, then number two must be true, and thus I am sure that Hell is exothermic and has already frozen over. The corollary of this theory is that since Hell has frozen over, it follows that it is not accepting any more souls and is therefore, extinct......leaving only Heaven, thereby proving the existence of a divine being which explains why, last night, Teresa kept shouting "Oh my God."

The student got an A."

Submission + - Chernobyl Mushrooms Feeding on Radiation

cowtamer writes: According to a National Geographic Article certain fungi can use ionizing radiation to perform "radiosynthesis" using the pigment melanin (the same one in our skin that protects us from UV radiation). It is speculated that this might be useful on long space voyages where energy from the Sun is not readily available.

Submission + - Electrostatic Magnet Motor Made from Kitchen Stuff (peswiki.com)

Sterling Allan writes: "Scott F. Hall, an associate professor of art at the University of Central Florida, was tinkering around with stuff in his kitchen and came up with a continuously rotating mechanism that appears to harness electrostatic energy from the atmosphere — or something. The gizmo spins at around 80 revolutions per minute, and is constructed from a can of dog food, tooth picks, refrigerator magnets, a pencil, spring clips, and a small corner cut out of a box. Three toothpics are formed into an inverted tripod and spin atop the fourth toothpick held vertical by a spring clip that has magnets situated around the base. A graphite pencil is held over the the point of the inverted tripod via another spring clip sitting atop the can of dog food. Hall (suitable last name) posted a video at YouTube showing the gizmo running. The next day, he posted another video showing a round paperweight spinning (though not continuously) via magnets placed on its perimeter, with magnets on two adjoining dog food cans."

Amazing isn't it? :)"

Submission + - Minn. Bridge Collapse is Just the Beginning

ntmokey writes: The nation's infrastructure is aging, heavily used, and dangerous, according to Stephen Flynn, a national security expert who wrote an op-ed piece for Popular Mechanics. Flynn believes incidents like the collapse of Minnesota's I-35 bridge and the recent explosion of a steam pipe in New York City are wake-up calls to our nation's leaders that we need to invest more in the structures we rely on (sometimes without even knowing it) every day. Our ports, roadways, railroads, air traffic control and electricity systems are were all top-notch when they were installed by previous generations — but we've come to take them for granted and we're starting to feel the sting of neglect. Flynn's not just waving red flags in light of recent events either, he wrote a book about the pending crisis that was published in February.
