Camera Obscure with Abelardo Morell: He covered all his windows with black plastic in order to achieve total darkness, he then cut a small hole in the same black plastic material, an image of the outside scenery was reflected directly on the opposite wall, but it was upside-down.

If Hoyoung Lee’s concept printer becomes reality, you’ll never throw away another pencil stub and never buy another ink cartridge. The pencil printer separates the wood from pencils and uses the lead to print documents. There’s even a built-in eraser component that allows you to remove text from a page and reuse the paper, so you’ll be saving money and trees.

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.’

Will anyone take a moment to read this?

This is my brother Mikey.

He has autism, and his birthday party is tomorrow.

My parents and I love my brother so much, I just wished other people felt the same way.

His birthday parties with relatives have never spent time with him or given him a gift. As if he didn’t understand.

His best friend (who was paid) never came back to see him since the summer …

and since then, we’ve been trying to find him new friends to hang out with.

My mom starts crying because she wants the best for her boy.

Most people don’t want to be friends with someone who’s “too different”… but I want to challenge this.

I want to show my mom and my brother how much people care about him.

He’s not going to have a big party like most would at 17, I will be thanking God if three people show up.

But could you spare a post on your blog for him?

I know someone out there thinks he’s worth it.<3
