Kitty Cannon experiments

Introduction

Object: To find the correlation between cannon angle and distance achieved.

Hypothesis: There are little correlation between angle fired and distance achieved, due to the randomness of the “obstacles”.

There is a game known as kitty cannon on the internet. The object of the game is to basically control the angle of the cannon with the up or down arrow key, then press space bar to fire. There is a red bar that goes in and out which indicates power. When the cannon are fired, the poor helpless kitty is shot out and will encounter the following obstacle:

Spike: The spike impales the kitty and ends the shot.

Venus fly trap: The fly trap eats the kitty, and ends the shot.

Trampoline: The trampoline will bounce the kitty up, however the bounce is exactly like a trampoline, which means the faster the kitty comes in, the faster it bounces out.

TNT: The crate of explosive causes the kitty to fly higher. Incoming angle or speed does not affect the amount of boost, but a kitty with a faster horizontal velocity gets a faster boost, whereas a slow kitty just gets shot up in the sky.

Bomb on a balloon: Has the exact same effect as the TNT, but the balloon hovers at random height. It does not matter if the kitty hits the bomb on the way up or down, the effects are the same (which defies the law of physics).

The premise is to get the highest horizontal distance possible (there are also challenges for the lowest horizontal distance possible). The natural question is, does the angle of the cannon affect the distance obtained in any way, and what angle would give the best chance of getting the 4000+ feet some have claimed to get?

Therefore the purpose of this experiment is to find out what is the best angle to shoot from, assuming maximum power is used.

Experiments

The experiment is conducted on an Acer 5920G laptop, with 2Gig of ram, Intel T7300 CPU, ATI HD 4950 video card with 512 GDDR3, and a 160G SATA hard drive. The game used is found on http://www.addictinggames.com/kittencannon.html .

Ten trials are used, with an interval of 5 degrees, from 10 degree (minimum) to 60 degree (maximum). To ensure constant power, the first result is discarded since there is no way to ensure that the power will be exactly the same for each trial. However the game allows a way of ensuring constant power, by pressing and holding space after each trial, the game will fire the kitty at 90% power. However there is no way to adjust the angle which is why the first result is always discarded.

No kitten or cats are harmed during this experiment.

Result

Conclusion

It would appear that there are little correlation between cannon angle and distance achieved, as it is just a matter of luck. However, the average distance achieved peaks out at around 35 degree, possibly due to the attribute of some of the obstacles. Moreover, it appears that very large distances are possible on any angle, given enough luck. Therefore there are little correlation between maximum distance achieved and angle of the cannon; however it appears that 35 degree gives the best chance of having a high average distance.

A prayer request

Hi

I have been praying and researching about a possibility of leaving Taiwan again in pursuit of opportunities to reach out to Muslims, but to experience other cultures at the same time. I have a few options however I want to commit this to prayer. I am sure that God would be delighted for me to leave Taiwan and receive opportunities to reach out to Muslims, and also to live the life that I am meant to live, and use the gift that are given to me by God for the benefit of mankind. My options now is to study for a master’s degree in either Geology or Chemistry. I hope to do this in Europe because the tuition of some countries are very low and it allows me the opportunity to get to know other students, many of whom will be Muslim, in order to fulfill the goals of reaching out to them, but also developing my God-given gifts to its fullest potential. In order for me to study in Europe, I must learn their language and take a language test (similar to TOEFL, but for German, French, Danish, etc.). My options now are to get enough money for 2 months of language study tuition, which I have, and enough for the cheapest forms of accommodation that are available for a period of time (2 months) even if it means sacrificing certain comforts. I have found a language school in Berlin which only requires around 300 euros a month for intensive language studies which is enough to get a language study visa. Some have suggested studying language in Taiwan, which I will while I am still here, if a free language class is available in German, however I will attend the Spanish class next week at the rock. I do feel however in order to be most effective in learning German, I must be in an environment where using German is mandatory, and not many people speak English in Berlin which is the perfect environment for this kind of thing. My plan is to study language for around 1 year, then take language tests and apply for a university.

Now I want to request a prayer from you guys. Please pray for God to reveal to me the proper timing for this kind of thing, because I have to make the plan at least 6 months ahead of time in order to allow for things such as visa and other administrative work, and I would prefer to go during an off season in order to save on travel costs (and alleviate any possible headache from not being able to find a flight). Also pray that if God wants me to go now (I can set things into motion now, might not be able to leave tomorrow but I should be able to in 3 months) that God will provide me financially during my time there, either through donation, goodwill, work opportunities, or even something as amazing as manna (like a YWAM base in China finding over 10,000 USD inside a loaf of bread they bought with the last money they had).

Finally I ask for your forgiveness for anything that I might have said, or done that is not within the character of Christ.

Amen.

This week I have spent a lot of time restoring the friend’s guitar. The work itself isn’t difficult with the right tool, but due to budget and space limitations I can’t use the kind of tools I hope I could use. The first portion of the week consists of obtaining the proper tools. When I say proper tool I really mean the bare minimum to get the job done, because I have a limited budget. If I had unlimited budget I’d probably get enough tools to outfit a wood shop, and a shop space to boot. I purchased a 2.5 HP compressor with a 5 gallon tank (8cfm or so), a Taiwanese clone of an Iwata W-101 spray gun (1.3mm tip) which appears to be well made, a Laminate trimmer made by a Taiwanese manufacturer (Rexon), a hand saw, hand plane, lacquers, epoxies, and many other accessories that are needed to get the job done. After that of course I have to actually get the work done. I used epoxy to glue the neck together because of a previous repair attempt, I have to make sure that the joint will not separate again. After that’s done (only to find out I mixed the epoxy incorrectly, resulting in a rubbery glue joint) I went ahead and cut 2 8mm slots into the back of the headstock in order to reinforce it with a mahogany plug. The cutting wasn’t perfect so I had to glue the wood plug in with epoxy in order to fill the gap, and fill all the tearouts at the same time. Today I simply leveled the wood plug and sanded the finish around the area off in preparation for refinishing. I plan to cover the reinforced area with black lacquer in order to hide the damage, it goes well with the guitar anyways.

Weekly journal (5/14-5/21/2010)

This week I did not do much until the middle of the week. I helped out Pastor Jeff of Oasis church in Taipei with materials and installation of curtains for a special ministry the church was doing. Later on I discussed about a friend I have who gave me a Gibson Les Paul Custom for repair. The guitar was well worn due to years of rock n roll lifestyle, and someone at some point had dropped the guitar causing the headstock to break. To make matters worse someone tried to “fix” it by drilling a wood screw to hold the break together, which obviously affects playability and sound, but detracts from its value as well. In short this guitar needs a lot of work and money to restore it to its former glory. I got into a discussion with someone else about the guitar owner’s inability to make a decision about his life, and I have decided that in order to motivate the owner of this guitar to take control of his life and do something, I am willing to sacrifice my plane ticket to Europe or DTS in order to invest in tools and equipments as well as supplies needed to bring this guitar back to its former glory. Basically what I will do is glue the break with epoxy, which is simple enough, but in order to prevent future breaks in that area I decided it needs reinforcements in the form of wooden splines that are inlaid into the joint, and since this inlay will not look pretty or original I decided I need to paint a burst around that area in order to hide it. After all this is said and done (will take a few months), this guitar will look as though it never broke in the first place, and it shouldn’t break in the future either. The equipments (which I had sold previously due to desperation) I need is an air compressor (at least 4CFM), a spray gun, a laminate trimmer with a 1/4″ bit, and some saws and possibly a plane for shaping the actual wooden “Popsicle stick” reinforcements. I have an estimated budget of about 10,000NT (around 300US) which is about how much it costs to have this guitar fixed by a luthier. Who knows, I may be able to fix guitars for a living from now on..

The meaning of prophecy

Many people, whether or not they are Christian, obsesses themselves with prophecy, especially doomsday prophecy such as the 2012 Mayan calendar thing. Movies have been made, scenarios have been planned, and even a doomsday shelter is in the works in response to these doomsday prophecies. The question is, should we even concern ourselves with these things, since the Bible says that tomorrow is never guaranteed anyways. Let’s consider what does prophets do, and why does God send them.

In the Bible we hear stories of many prophets, and Old Testament laws have sections dedicated to prophets. One law says that a false prophet should be put to death, and that if the things a prophet does not come to pass, then he should die. Of course there are many obsessions about the prophecy concerning Jesus, and the end of days in the book of Daniel, Isiah, and Jeremiah, and Revelations. The fact is, these doomsday prophecies, and even prophecies concerning the Messiah only makes up less than 1% of the prophecies in these books! I learned in a church sermon that the purpose of a prophet is to edify and strengthen the people of their time, that means prophets like Isiah and Jeremiah and Daniel wasn’t sent for future generations, but for their generation! I will not go into the specifics of their prophecy but it’s safe to say that most of the things in their books deals with things that are happening in their time. Some people have the gift of prophecy too, not just people with “qualifications”. For example I was prayed for by the pastor’s wife of a Philipino church in Taiwan. The thing she prayed it was almost as though she knows that I was called into missions, even though she doesn’t know me (I had only been there for the first time) and certainly she did not know of my blog nor did anyone tell her that I wanted to preach to Muslims. It was very edifying, unlike many prayers I have heard before.

What I am trying to say is, don’t be so concerned about doomsday prophecies, because the Bible clearly says not to worry about tomorrow for today has enough evils of its own. I would be more concerned about finding out what God wants you to do today, and how can I build the Kingdom of God rather than listen to Hollywood and its doomsday messages that are designed to put fear into the people’s heart in order to sell more movies. Someone said it best when he said that yesterday is gone, and tomorrow might never come.

New host

I had previously used a paid host, but I discovered that there are many free blog host out there, and since I am using wordpress (and it meets most of my needs) I just moved my page to wordpress and paid a 10 dollar per year payment (rather than per month) to host my domain, so the web address are unchanged.

More night views

These images are shot with a Canon EOS 400D with the kit lens (18-55 3.5-5.6, non IS) at ISO 100 (one is 400 because I forgot to change it) with exposure time ranging from 15 seconds to 25 seconds. Then I used lightzone to sharpen and brighten the image to make it look better. More tedious compared to a point and shoot (since the camera does all that) but more control, and this kind of shot simply isn’t possible with a point and shoot…

Image is shrunk to save space (on the page) and bandwidth. If you want to view a larger version look at my facebook profile (my name is Tai Fu) or email me for the raw files if I still have it…

This is done with a point and shoot, ISO 100, 15 sec exposure (maximum allowed)

This is done with a point and shoot (Canon Powershot A620), ISO 100, 15 sec exposure (maximum allowed). Image is VERY noisy, brightening makes it worse, and sharpening it makes it look like clown

This is done with a DSLR, ISO 400, 15 sec exposure, the difference is huge! These images are brightened and sharpened with Lightzone

A new camera

I just got a Canon EOS 400D and I decided to just have fun taking pictures… photography is expensive by the way because they like to charge over $300 dollars for even cheap lenses. Well you have cheap and good lenses like 50mm f/1.8 for around $100 but everything else costs way more, so some creativity is needed. I love macro and honestly I don’t think I will have money to go around buying macro lenses seeing that they START at $600! Makes the camera look cheap in comparison. I might try and turn one of my lens into a macro lens by using a pringle can… (or buy a cheap FD lens just for that purpose)

I really love night shots though, and this camera opened a lot of possibility. Night shots are difficult, even with a DSLR, and most likely impossible with a point and shoot (unless you are really good) because you need long exposure times, big aperture and very steady hands (or a tripod). With a DSLR things are a little easier since you not only have more control, but with a fast lens like the 50mm f/1.8 you can hand hold most shots if you are shooting something illuminated with a street light, anything darker and you will require a tripod, since you’d have to expose for many seconds or longer…

Sorry I have been gone

Sorry that I have been gone for a while. I spent the last few weeks resting, and deciding what to do, and all the while I was working on translations which is pretty busy in itself. I think God has been good now that I have more time to reconnect with friends, but that connection takes time to rebuild. I have managed to meet with a muslim here and there, but since there are so few it’s difficult to really find out where they meet other than going to a mosque, and even then half of the people who attend are expats. I have realized it’s not safe to go to the mosque every week because I would be sending a message that I want to become a Muslim if I keep going, and if I didn’t they would think something is wrong. I pray that God will direct me to a place to meet people from an Islamic family but not really too religious, because those people are easier to talk to.
