Once there were a number of bats. They lived near a neighborhood of old houses. During the late summer months they like to sneak inside one of the old houses and fly about in the middle of the night, causing the human residents a great deal of consternation. Once they do so, the large male human captures them in a plastic box and releases them back outside. About half the time they don't survive the capture procedure  , which bothers the large male human not at all. The End.

True. The large male human has a goal of at least one summer where not a single bat gets inside his house. In the last ten years, I've had at least one every summer, and some years a half dozen or so.

How are they coming inside in the first place? Perhaps you should seal of all entrances, at least to a point where bats can no longer enter. There's special screens you can place in open doors or windows that keeps bugs out (and probably bats too). Something like this screen door[^].

It's a large (2400 sq. ft.) old house, built in 1872. Our local bats are small, and can get in through an opening as small as 1 inch by ½ inch. I've sealed chimneys, replaced window screens, etc.
It's an ongoing battle to keep the critters out. We also have raccoons and squirrels that like to try and get into our attic. At one point last year we had raccoons tearing the screens out of an upstairs window to get into the room where our cats' food bowls were. I got up one morning and found the plastic food container had been dragged out onto the roof  .

They sound like cheeky and persistent little critters...
Isn't there some stuff that keeps them away? Something they can smell, but humans can't or some sort.
If all else fails you could become a critter yourself and sneak into others homes to eat and sleep. If you can't beat 'em, join 'em

Raccoons are the worst of the lot. They're destructive, fearless, and can be combative if cornered. The local population is positive for rabies about 50% of the time.Sander Rossel wrote: Isn't there some stuff that keeps them away? Something they can smell, but humans can't or some sort
Most of those sorts of things either don't work well, or they smell so bad the cure is worse than the disease.

Not to sure why they put observatories in cities. I would have thought there would be to much light from street light etc. I find it easier to just go outside and look. (advantages of not being in the country)

Cool link thanks

I did not think it was possible, but there IS something worse than math (well, it's still partly math, but not entirely).
Coming saturday I'm taking my third chance at an exam about communication technology. It's part math, part physics and completely impossible.
Stuff I should know is how a telephone works, how radio works, how a modem works, how the internet works, etc.
We have waves that travel at a certain frequency and there's noise on the channel and we can multiplex it and convert it to bytes using transducers, put it back on a wave using modulators, put a sinus function in there, magically apply cosinus, of course we need to remove redundancy, add line coding and channel coding... And of course there's all kinds of formulae to calculate stuff. AAAARGHHHH!!!
I scored a 4 twice (on a scale from 1 to 10 with 10 being the highest score). It's 40 multiple choice questions and I answered 23 questions correctly (twice, at least I'm not un-learning), but I need 27 correct questions for a 5,5 (passing grade). Which makes this even more impossible.
Is anyone here working in the field? Or knows a bit about it?
Any tips that might make me see the light?
Why did I ever want to study again?

No problem for that, everyone is able too. However, if wath you really want to know are the laws of light propagation then you have to...

There is your problem, you are defeatest...If it were impossible, then nobody else would have passed it.
Sander Rossel wrote: It's 40 multiple choice questions
At least you have something to select from. MC is a lot easier that questions where you have to 'describe' or 'explain' or 'prove' and are simply presented with a blank space to start writing.
Get a hold of practice papers and do them and keep doing them. I found the practice papers for my degree really helped to give you a feeling of what was coming your way and what was expected.
If all else fails, just keep rehearsing the magic phrase...."You want fries with that?"

There's a chance you'll get 40/40 correct with no prior knowledge about the subject. Luckily I know nothing about calculating chances so I'm just going to assume it could happen to me coming saturday

I disagree. When I get to describe something I can usually write at least something down that gives me points.
With multiple choice it's either good or wrong. And I'm more wrong than not (in this case).
DaveAuld wrote: Get a hold of practice papers and do them and keep doing them.
I passed the two practice exams. They require only 20/40 correct answers though. Imagine my disappointment when I found out I needed 27/40 for the real exam 
I already hold a degree in art... Allright, maybe I better start rehearsing that phrase

Just because you passed the practice exams with 20/40, doesn't mean you stop doing them, you keep re-doing them until you get 40/40, that way the information is sticking in.

There are a lot of websites available.
What specifically are you studying?

I'm studying IT, but this course is about communications technology.
It's mostly math and physics that come together in hardware like modems, transmission towers, (mobile) phones, etc.

After this course my inquisitive mind is a bit less inquisitive
Nah, I probably couldn't stop learning. I'll just stay away from math for awhile...

What is the school you are attending?
My degree is in electrical engineering and I took a communications course in school decades ago. The theory has not changed since then. It helped that I was into amateur radio because I knew what theory was likely to show up on tests, and what was used less often.
The communications exams I took had algebra and calculus. They were not typically multiple choice exams.
I don't know what to tell you other than to study the course material. I could give tips, but I might tell you to study things that aren't on the exam.
Do you have any specific questions?

I'm studying at the Open University, so I'm not attending anything. I do all my study at home.
Being into amateur radio would've helped me a lot. There's a lot about (radio)waves, frequencies, transmissing, AM, FM, PM (Phase Modulation), ASK (Amplitude Shift Keying), FSK, PSK and QAM (Quadrature Amplitude Modulation).
Unfortunately, I'm not technical at all. I know how to switch on a computer and that's where my hardware knowledge stops. That is also the reason I started to study. I want to know more about computers and technologies in general (like email, networks, internet, hardware, etc.).
I started programming in .NET a few years ago, but before that I had little knowledge of anything computer related. I was a gamer, so at least I knew how to install software and troubleshoot some minor problems (with the help of my good friend Google, of course).
I can be pretty into something, so I learned a lot about programming in a short time. I wrote my first article here on CP after four months and won a prize in the first year. But I still didn't know anything besides .NET (and some general programming knowledge), so I enrolled for some OU courses.
After seeing all the math I have to do I'm not so sure if I want it anymore (I can get into anything, except math). The only problem with this course is the math really.
I should write an article about math and treat it like a programming problem. If I did that I'd know more about math than my study ever required. My mind is not ready for it though...
