Here’s another one for the zombie apocalypse survival kit. You can now cook a pack of Ramen and charge your iPhone at the same time. You’ll be able to eat some noodles while making a call on your wood-smoke-smelling phone from the backcountry (provided cell towers still have power). The BioLite CampStove converts heat generated from your stove into electricity to charge USB gadgets. I suspect it’s not the most efficient charger in the world, but it’s the only one that will still works off a campfire.
This answer to a college chemistry exam was sent to me recently and restores my faith in the new generation of college students. The answer was purportedly in response to the bonus question on a University of Arizona chemistry midterm: “Is Hell exothermic (gives off heat) or endothermic (absorbs heat)?”
Here is the student’s answer:
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, which is unlikely. 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 reportedly received a well-deserved A+
John Doerr asked Gates how he met his wife, Melinda.
"At work," Gates reportedly said. "Back when that was okay."
