An arrow is formed in a 2 2 square by joining the bottom corners to the midpoint of the top edge and the centre of the square.
Find the area of the arrow.Problem 2:
Two ladders are placed on opposite diagonals in an alley such that one ladder reaches a units up one wall, the other ladder reaches b units up the opposite wall and they intersect h units above the ground.
Prove the following result.
Consider the two diagrams below.
The area of the square is 4, so the area of the large triangle is 2 (half of the square) and the area of the small triangle is 1 (quarter of the square).
Hence the area of the arrow is 2 1 = 1 square unit.Solution to 2:
Consider the following diagram:
By similar triangles:
x + y
and x + y
x + y
+ x + y
= x + y
Dividing by (x + y):
As 21000 is not a multiple of 10, it follows that,
10m 21000 10m + 1, where 10m contains m + 1 digits.
Solving 21000 = 10k, where m k m + 1
k = log 21000 = 1000 log 2 301.02999... , so m = [1000 log 2] = 301.
Hence 21000 contains 302 digits.The problems and solutions are all taken from http://www.mathschallenge.net

Unlike many, due to my excellent support from people I was very quick in first seeking help with my OCD, it is thought that most with OCD suffer in silence for many years before seeking help, not knowing they have a disorder and can be helped and only getting help when they have slipped down into a state where they are completely incapacitated by the disorder. If you are struggling with what might be OCD, do not let this happen to you, there is help out there.
I went a grand total of about a month before I seeked help for my OCD. Where I would be and what state I would be in today I do not know if I was not pushed to seek help at such an early stage by loved ones close to me. The first thing I did was went to see my doctor and vaguely explained the thoughts that were going through my mind. I was blessed with a doctor who knew about OCD, this is a lot less common than I had suspected and I have heard of many who do not know about OCD and leave patients stranded, if your doctor does not understand, go and see another one! My doctor put me on what is called an SSRI medication (or an antidepressant) called Fluoxetine, which is the generic name for a much more commonly known medication, Prozac. I have to admit I was concerned to begin with, I thought taking the medication meant I was crazy and if I wasn't crazy already then the medication would make me so.
After doing some research and with instruction from my doctor I began on the medication with instructions that the medication can take longer to help than for depression, infact it can take up to 10 weeks. I was also told that sometimes the medications does not help at all and that I may need to try several different SSRI medications before one is helpful. I was also told that the dosage required varies from person to person and that getting mine right may take time.
I however was blessed, the medication while initially making my thoughts stronger, did help me out within about four weeks. They certainly didn't stop the thoughts but they did begin to mean I could focus some of the time on other things and begin to live a more normal life again.
I was also told that seeing a psychologist to do Cognitive Behaviour Therapy (CBT) and Exposure & Response Prevention (ERP) was the next step in controlling my disorder, however, the waiting list was long and it was going to be another year or so before I was able to see a psycholgist, I will talk about these methods and my experiences in a later post.
My next post will probably be on Christianity & Medication, as a christian I have come across many well meaning christians who argue that taking medication is unbiblical, unneccessary and wrong. I disagree strongly with this position and will hope to help christians struggling with this issue in the next post.
I remember the day OCD first hit me vividly, although I did not know it was OCD at the time. I didn't really understand what was going on, only that one thought suddenly came into my mind and began revolving around causing feelings i'd never experienced before. The thought, a fairly common one, one many people experience and let pass by. The thought, I would rather not say and the content of the thought is infact irrelevant to the experience of OCD. For an obsession all is needed is for something to be important to you. I knew at the time my reaction to the thought was over the top but that didn't make it feel any less real or any less disturbing. The more I tried to fight against the thought, the stronger and stronger the thought got. The obsession was more than just a song stuck in your head type experience, there were mental and physical consequences. The thoughts were accompanied by my chest tightening, my shoulders cramping and a paralyzing state of fear. As a consequence, I struggled to sleep, never felt like eating (although I forced myself to) and my ability to concentrate on anything else slipped to almost zero.
I however was blessed, I had great support from certain people and quickly discovered what OCD was and that I was suffering with it, this was however only the beginning of my encounter with OCD that continues to this day. I will explain more of my experiences soon.
I thought I would begin discussing OCD today, however my aim is to do this in several blog entries, the aim is also not to simply repeat what can easily be found elsewhere online. However, this post in particular will contain information from elsewhere, this is simply for convenience and because these terms will be used frequently. My purpose is to describe the disease in my own terms, in terms of my own journey with the illness, both the ups and the downs.
A Few Technical Terms
The thought or event which causes the sufferer to obsess.
A Couple of Examples of Spikes:
1) A heterosexual man is making love with his wife when the name of his male best friend happens to flash through his mind.
2) A passenger is waiting on a train platform while the train is coming.He has a thought of what if he did a sudden erroneous movement and fell under the train.The above are both taken from http://www.neurointerests.com/?p=19 this site talks about a slightly different form of OCD called Pure-O which I will probably touch upon in further entries.
Some Good OCD Websites:
www.neuroticplanet.com - This is a good website for articles on OCD and some further links, it also has an active discussion group with many people struggling with OCD. Forum requires registration.
http://health.groups.yahoo.com/group/the_scrupe_group/ - An excellent forum monitored by a former Lutheran pastor for those suffering with Scrupulosity (Religious Obsessions). Forum requires registration.
http://www.ocdonline.com - A very good site with lots of articles on OCD written by an expert in the field, as with all things in my opinion some articles are stronger than others, the one most people recommend is the article on Homosexual OCD & Relationship OCD called I Think it Moved, the site is worth a visit for all suffering with OCD.
I thought that now this blog was in a reasonable state with a few entries I would give an explanation of this blog and some of the things on it, most of it is very straight forward and self explanatory but I will explain as much as I can anyway.
What you may see at the moment is that all of the entries are about software, this is not planned to always be the case. I have had a lot of time at home recently and have spent a lot of time on my computer and so have found several things to blog about, expect the diversity of things to improve as time goes on. I am hopeful of entries on Christianity, Obsessive Compulsive Disorder, Big sports events and many other things, there is also a possibility of some articles written by others on topics they are considerably more specialised on, these will be clearly labelled to give credit to the author.
The links section on the website may expand, shrink or stay as it is. Its aim is to feature things that are related to the primary goals of the blog. These goals may however change over time and thus the links may change with it. I will aim to keep these links in some sort of order, at the moment they are ordered in category, if the list gets large I may switch this to be alphabetic or another method.
If anyone would like to have an article on this blog feel free to email me with the article and your name, if I feel it is appropriate I will post it, if I feel it is inappropriate I will do my best to respond with my reasoning as to why I haven't posted it.
My aim is to keep this blog updated on a regular basis but I will try not to post just for the sake of posting, my hope is that all of my posts will either be entertaining or of use to someone.
If you have any comments about the blog, also feel free to email me.

Lyx, is a word processor and so offers similar functionality to Microsoft Word and Open Office Writer, it however works on a different principle which not only makes things look better, it also makes things easier!
Standard word processors work on a WYSIWYG (What you say is what you get) principle, that is to say that what you see on the screen in front of you is what will be printed, in theory this sounds a good idea, in practice however it means you spend a lot of your time actually formatiing your document (i.e. Bold, Italics, Font Size, Page Layout etc) and so spend less time actually focussing on what you are writing.
Lyx works on a WYSIWYM (What you see is what you mean) principle, that means using Lyx at first seems a little bit strange because it does so much for you, if your writing a paragraph, you tell Lyx thats what your doing and it sets everything for you, tell it you are writing a Title and again it sets everything for you. It also has proper setups for Theses, Articles etc.
The above is a graphical tour of Lyx and should give you an idea of what it is all about. In addition to the great simplicity and beautiful output you get from it (Put it next to a MS Word document to see what I mean!) it also does several other things extremely well:
1) After finishing your writing you can automatically create a contents page with everything done perfectly.
2) If you use bibliographies this is also greatly simplified and much improved.
3) It works using Tex, which is a type setting format, this is especially useful if you are implementing mathematical formulae as it doesn't require any knowledge of Tex inputs but gives you the brilliant output of Tex.
I must say that this is one package that really impressed me when I tried it, it is a small download and worth a try out for anyone who uses a word processor and wants nicer output than they normally get, also excellent if using bibliographies and contents pages as it saves a huge amount of effort doing these manually.
It is worth noting that due to the WYSIWYM principle it does take a small amount of time to get used to, fortunately there is an excellent tutorial located in the help menu to help you get to grips with it.
The package is available on both Linux and Windows
I have a link for this in the links section of this blog but I thought it was worth adding again with a more full explanation about it.
1) Ubuntu is an Operating System (OS), a more common example of an OS is Microsoft Windows, it is a Linux distribution.
2) Ubuntu is completely free, that is free as in it costs nothing and you are free to see how it was made, change it and do anything you want with it! That is to say the source code (how it is written) is available.
3) It ships with approximately 18,000 applications which are also all completely free!
4) You don't have to install it to try it, you can run it DIRECTLY from the CD to see what you think, they'll even send you a CD completely free, you don't even pay the postage!
The not quite so basics:
In the basics we've touched on some reasons for using Ubuntu instead of Windows, i.e. Its free and software for it is free also, there are however several other good reasons for using it:
1) Its fast, and I mean really fast, on a fast computer it absolutely flies but even better if you have an older computer that struggles to run windows XP, chances are Ubuntu will run perfectly on it.
2) Its stable, if you often get lock ups and problems with Windows, such as the dreaded blue screen of death, you rarely if ever get these in Ubuntu.
3) No viruses, no spyware, no adware! Almost all viruses are written for Windows and even if they were written for Linux, because the Source Code is available, the clever people would immediately spot viruses.
4) If you don't play the latest games there is essentially NOTHING you cannot do in Ubuntu and for free! If you do play the latest games (like me) there are ways to get some working in Ubuntu but you can install Windows and Ubuntu like I do.
5) The software available really is excellent, popular software also used on Windows would be Open Office & Firefox, my personal favourites in Ubuntu are Qalculate (A really advanced calculator), Inkscape (Excellent and easy to use for drawing), Listen (Think ITunes but nicer), Gimp (For editing photos) & Audacity (Easy editing of Audio)
6) You have four desktops instead of one and can use them all at the same time!
The fairly advanced:
These things are really good but they're not common to Microsoft Windows so they may sound a little bit strange.
1) The Terminal, this is a place where you can type things in and things happen! You can install applications, run applications, edit files, update your computer, fix your computer, turn it off and anything else you can do in an OS all from the terminal. Doesn't sound very useful but I can promise you that once your used to using it, its hard to be without it!
2) XGL & Compiz, this is a new type of desktop that looks awesome!
That is a video of this in Ubuntu, its German I think but you don't need the audio anyway!
3) www.ubuntuforums.org, if you do decide to install Ubuntu these forums are unbelievably helpful, they'll help anybody out on any question at all!
So thats my basic run down of Ubuntu, i'm completely sold on it and have it set up to do all my work in and windows for when I want to play games! It's great, try it!
I saw about this guy in the newspaper, his responses are a bit slow but he's quite interesting and very intelligent! Apparently the most intelligent robot of the lot! Give him a try and see what you think!
A new web browser for anyone to take a look at,
1) Excellent if you use blogs, makes them so easy to use!
