Picture this, you have an array of 1,000,000 light bulbs, numbered 1 to 1,000,000, all of which are off (and all of which work). The following task involves these light bulbs and an action we'll call "flipping". Flipping simply means changing the state of a light bulb. If the bulb is off, flipping will turn it on. If the bulb is on, flipping it will turn it off. Starting with all the light bulbs off, you start at bulb #1, and flip the state of every bulb. Once you've done that, you go back and start with bulb #2, flipping the state of every second bulb. Next, you go back, start with bulb #3, and flip the state of every third bulb. This continues all the way up to 1,000,000, where you flip the state of every "millionth" bulb (obviously, just the one bulb). Here's the question: After performing this massive task, which light bulbs will be on, and which light bulbs will be off? Enjoy! Ryan Jones

The mathematical constants are, the 48 there is not Cheers, Ryan Jones

I love science as a whole but chemistry has always been me favourite I think. I love the maths, I love the experiemnts and I love watching the reults and working out how everything happened - how better to use ones time Cheers, Ryan Jones

I'm currently studdying Chemistry, Physics and Biology as well as Maths, I find them all of very high interest but some day hope to be come a chemist but I'll probably keep studdying Biology, Physics and Maths out of pure interest Cheers, Ryan Jones

Thanks for the infromation guys - very helpful One more question - what would such a strong acid be used for and what would its PH be in aqueous solution? Thanks for the information again, Ryan Jones

Maybe they are refering about a relative mass...? Cheers, Ryan Jones

Hi everyone... I have a love for chemitry and some day hope to become a chemist I have a question: what is the strongest acid known, what is its PH and formula? Are there any prospects for stronger acids to be produced in the future? Thanks for the help, Ryan Jones

Hi everyone! Here's the ongoing challenge: Using any mathematical operations you want, but only four 4s (Or less) for the numbers, create equations to equal as many numbers as possible. Here are the rules: 1. All four "4"s must be used in each equation. 2. No other numbers can be used in the equations. 3. You may use any mathematical operations and symbols (not including symbols for other numbers, like Pi, e, etc.) you wish. 4. The answers in this thread will start with trying to find an answer resulting in 1, then the next person must find a solution resulting in 2, the next person 3, and so on. 5. This is to continue as long as answers can be found. 6. The winner will be considered the person who has found the answer to the highest number. They will remain the winner until the next highest answer is found. I'll start this thread off with a solution for 1: [math](4/4) * (4/4) = 1[/math] So, how about a solution for 2? Cheers, Ryan Jones

Thanks for the advice Cheers, Ryan Jones

Quite true - never thought of it that way! But I actually meant moving the particle(s) without avtually moving them in the way you did with the coffee cup Something like moving a coffeecup accross the galazy without going there is what I was getting at. One thing, even if there were a posibility it could be done (Even if not with our current technology level) - working out a co-ordinated way of altering a probability wave is something I can't even start to think about! @Xyph - very interesting, never heared something even remotly simmilar had been done!

Hi everyone! I was recently reading a book called "The fabric of the cosmos" and it has quite a lot of things in there and one of them was thae idea that particles only have an absolute position when viewed otherwise they are thougtht to exist as a probability wave, the particle has x probability of being here and y probability of being there. If this is correct, would it be possible to manupulate the probability wave on any level? if you could then in theory you could make a sort of matter transporter my altering the probaility wave of all the constituents and thus making it certain that they exist in one poinet over another. That make any sence to anyone? I would not think you could alter the probability waves in any way shape or form but Id just like to see what you guys think Cheers, Ryan Jones

Ok, thanks both Cheers, Ryan Jones

Thanks Ricker In that case, how can these travel at light speed? Anything with mass accelerated to light speed gains infinate mass and thus cannot travel light speed - am I wrong? This has been bugging me for a while, if I have made a mistake then pleas epoint it out Cheers, Ryan Jones

Does light have mass - a question relating to this question requires this bit of information. Does it also mean that if light can be said to have mass then does all energy have some mass (How ever small)? Thanks for the help, another question to come if the outcome is as I think it is Cheers, Ryan Jones

Ok, here is the question (From an old textbook I found...) Princess Amira demands only the most luxurious of accommodations. So for her bath, she had glacial ice from Terror Mountain shipped to her palace in the Lost Desert. There, the ice was carved into a perfect sphere, exactly 2 meters in diameter. The ice sphere melted into her hexagonal bath measuring 1.5 meters on a side, and 0.8 meters deep. If the desert heat uniformly melts the surface of the ice at a rate of 1.5mm of depth per minute, how many minutes will it take for her bath to be completely full? Please round up to the nearest minute, and assume the volume does not change between solid and liquid states. Anyone have any idea as too the answer... i have been trying for a while and lets just say I'm getting annoyed with it right now as it is 1 AM here Cheers, RyanJ
