So, I'm going to be a camp counselor this summer, and I'm basically just looking for any ideas you guys might have. Basically, any outdoors games, or games that can be played with simple materials. or, any interesting woodsy stuff... like orienteering or what have you. typical stuff... I'm sure...

I was hoping you guys would share your stories of perpetual motion schemes and wacky theories of that nature. The more our understanding of the laws of physics grow the more the human imagination wants to break them.

This is a really fun probl, I've been trying to get for a while: A 600 N man stands on a bathroom scale on elevator. After, it starts moving the scale reads 900 N. Find Acceleration (magnitude/direction) EF = ma weight - T = ma wt - T = ma (600 N)(9.8 m/sec2) - T = ma i noticed i didn't...

Aero, EE, ME?? which one is fun? My high school finally ended yesterday, and now i am so confused about my future education... and here is my story i came to USA during high school, this didnt do anything good because the confusion of GPA. It ended up very bad that every good engineering...

Giant Paper Tower :) Fun Hello, My physic's class has been kicking butt all year, so much in fact that we are done with the book early. My teacher is having a contest for us. Build the tallest paper tower we can... ONLY using paper, but as much paper as we want. Construction MUST take place...

Find the flaw in the following reasoning: -4 = -4 \frac{-4}{1} = \frac{4}{-1} \sqrt{\frac{-4}{1}} = \sqrt{\frac{4}{-1}} \frac{\sqrt{-4}}{1} = \frac{\sqrt{4}}{\sqrt{-1}} \frac{\sqrt{-1}\sqrt{4}}{1} = \frac{\sqrt{4}}{\sqrt{-1}} \frac{2i}{1} = \frac{2}{i} 2i^2 = 2 -2 = 2...

Q: A 55.3 kg person jumps from a window to a fire net 21.9 m below, which stretches the net 1.04 m. Assume that the net behaves like a simple spring, and calculate how much it would stretch if the same person were lying in it. Here's what I did: using conservation of energy to get the...

http://pacific.uta.edu/~qiming/Project2.htm Mind you this is solving NUMERICALLY(hence Euler's algorithm)not analytically *THIS FOLLOWING PART IS JUST ME EXPLAINING WHAT I DID, it's hard to put into words, if you can follow it and spotted a mistake, let me know* quick assist to get you...

Quantum Physics... And you thought this thread was going to be serious.[/size] Anyway ... finally, today quantum physics was started in my college lectures. Most people in the room hated the sound of it but I was ready to go. After the lesson my friend said 'I didn't realize quantum...

Are there any other geology/palaentology enthusiasts that like to do a spot of fossil collecting when they get a chance? Or maybe you don't like geology, but just think ammonites are cool? What were your best finds? Where are your favorite fossil hunting spots? Photos would be nice. I...

For a brayton cycle on a pressure and temperature diagram, using helium gas, is it reasonable to have the net work for the cycle and the change in Q for the cycle to come out to be equal to each other?

Yesterday I filled my tank and it cost $40. I walked back into the office grumpy about this only to find one of my co-workers had emailed these to me: http://img236.exs.cx/img236/8493/pic002485kp.th.jpg http://img236.exs.cx/img236/1736/pic006114xo.th.jpg...

As a college student I have a lot of extra soda cans around I thought it would be neat to tryto have some fun with them. What I would like to do is make some sort of solenoid or system of solenoids that would launch a soda can. What I am wondering is if an aluminum can is afected at all by the...

Hi, I am playing around with doing stuff recursively, just to practice, and I have a problem I can't work out. I want to write a recursive function that will sum the digits of a number, take the result, sum those digits, etc. until I reach a single digit number. Then I want to return that...

Is it really fun to shoot people?? Re a quote I read this week in Newsweek: Spoken by Lt Gen James Mattis Is it just me that thinks guys like this should be thrown in the stockade? I'm not an American but I would sure like to know what Americans and others think of this mentality. And...

obviously it wasnt told as a myth to me. But has anyone heard this? It's biology and physics mixed. Basically I'll paraphrase to my version messing up points that probably are meant to happen. There is a woman she becomes preggo. She's goes to get ultrasound when its time or whatever...

what is the process for combining 2 equations?

A particle moves in the xy plane with constant acceleration. At time zero, the particle is at x = 2m, y = 1.5m, and has velocity Vo =(3.3m/s)i + (-7m/s)j. The accelerationis given by a = (6m/s^2) i + (5.5 m/s^2)j. What is the x component of velocity afer 1.5s? im stuck

Looking for ways to liven up your next quantum physics party? Shine a light through a polarized lens. Align and rotate a 2nd lens until the light intensity is reduced to 50%. Align and rotate a 3rd lens until the light intensity is reduced to 25%. Next ask your guests what will happen to the...

Explain why a point on the rim of a tire has an acceleration when the tire is on a car that is moving at a constant linear velocity :cry: :smile: :mad: :rolleyes: :approve:

Some fun tidbits. A law passed in Nebraska in 1912 really set down some hard rules of the road. Drivers in the country at night were required to stop every 150 yards, send up a skyrocket, then wait eight minutes for the road to clear before proceeding cautiously, all the while blowing their...

:biggrin: Thanks 42, the feeling is http://www.baker-street.net/tiger/ . :smile::-p

Friend's birthday I have decided that the post was not appropiate before so I edited it. The short summary of what was there was about my friend's birthday party. It was the girl I went to winter formal with and it was a very interesting experience. Abour 40-50 kids met at Damon's for dinner...

Does anyone know any laser jokes? I'm doing a short presentation on laser diodes and thought it might be fun to include a refreshing page of jokes near the end. I found a few on Google, but none were very funny.

Fun game! Participate if you can! Alright I'll try to make this brief. The rules: PM with your guess of a non-negative integer (ie. 0, 1, 2, 3, 4, 5, 6, 7...) The winner(s) will be the ones who choose the least number with the least number of pickers. For example, if there are 5 people...

Here's the Question : A 5.00-kg mass is on the end of a massless rigid rod of length l=70.0cm which pivots freely about the other end. The mass is moving in a verticle circle. When the rod makes an angle of theta=55.0° with the horizontal, the speed of the mass is 1.60 m/s. a) calculate...

Three identical masses of 650 kg each are placed on the x-axis. One mass is at -13.0 cm, one is at the origin, and one is at 42.0 cm. What is the magnitude of the net gravitational force on the mass at the origin, due to the other two masses? I solved this problem in the homeowrk section of...

Mining Games! i didn't know if this was suited for the engineering forum or the general discussion, since its about engineering but its not a question, if I'm in the wrong forum please forgive me here goes, I'm so pumped i made my schools engineering mining games team, i am the the only...

My experiment is simple in essence: Its title is, “times for a trolley to roll down slopes of differing lengths and inclinations.” So basically I have a slope and I let a trolley slide down it from differing lengths and inclinations timing how long it takes to get to the bottom of the slope – I...

Halloween Fun -- Tetris Inspired Here is some halloween-costume fun. I guess Tetris has had a vast impact on their life. :rolleyes: http://blog.f00kie.com/files/tetris1.wmv http://blog.f00kie.com/pics/tetris1/tetris6_small.jpg

here is one of my favorites Ok, Imagine you are on a small island. Now, At this moment, lava is cascading down all sides of a volcano. You can not stay on this island and survive. Now, in the water surrounding this island their is a complete ring of people in boats with guns, who have to...

A child is lying on her back. The tension in the muscles of her neck is 55N as she raises her head to look past her toes and out the motel window. Ten minutes later she is screaming and sliding feet first down a water slide at a constant speed of 5.7 m/s in a horizontal curve of radius 2.40 m...

Picture two indentical circles with their radii overlapping. They form an intersection, what is the area of their intersection? I solved it the calculus route and it can be solved geometrically. Have fun.

Happy Halloween!

Many of the people here hate school, but I love school. Beneath all the hard work is fun, entertainment and an endless supply of excuses. Most of you probably don't even realized how great these things are until you've lost them. For starters, the girls are great. Where else do you get to sit...

Any help would be greatly appreciated. Thanks in advance. A stone is thrown vertically upward at a speed of 45.50 m/s at time t=0. A second stone is thrown upward with the same speed 3.810 seconds later. 1) At what time are the two stones at the same height? 2) At what height do the...

What is it with them that makes them deserve it, while I have to miss out? What am I a spastic? I guess the fun comes in proportion with how much you are above a spastic... but if I know this then how could I be unaware, un-spastic?

As some theory resuly, in p or n, there is a tini wormhole, to pass the tini hole, only by a neutrino. Naturely lower enerty is super. To freeze p or n self whirlpoor in one direction by strong enough magnetic field. and pole the neutrino by strong laser beam structure. After some neutrino to...

Hello all, I am wanting to major in physics, and plan on going to graduate school. I am only in my freshman year, and taking basic classes but the math classes are very fun. Are the graduate level classes for the maths and physics fun?

Something occurred to me tonight as I watched the latest on the Iraq situation. I am just passing this on as some wild speculation that seems to make a bit of sense. Going into the war, I was extremely concerned that we had been duped. To me, Powell's presentation to the UN had all the...

American dignity and freedom in Iraq? The great feeling of having the power? Shame on US ... bring prisoners to JUSTICE ?. What justice? Sick Justice. A photo from TV shows an Iraqi prisoner with a hood over his head, standing on a box and with wires connected to his hands. Photo: Sky News...

Fun problem: ? x / (x^2 + 6x + 10) dx Integration by parts proves 1=1! My mathematical fame is at hand! So how would you do this one?

How would the concept of having fun benefit animals? To the point in which natural selection favors animals that have fun over animals that do not have fun. I know it would benefit young animals, but how would the concept of fun benefit an older animal, especially to the point in which...

I'm thinking of throwing a party in three months or so. A fad that has been getting more popular lately is a foam party. To do this you need a foam machine. Rental for one of these units is well above $100, and sometimes around $400. That's a little pricy for my budget, but I figure that with a...

Just abit of fun! Find a 5 digit number that: · Has no two identical digits. · Has two digits that are perfect squares. · Has two digits that are prime. · Has one digit that is neither prime, or a perfect square. · That has the second digit six less than the fourth...

Here's a little puzzle that may provide some amusement. (I hope it's not too trivial!) I have attached a (rough) diagram to accompany the following description. Consider an empty tank with a circular hole in its bottom. (The tank is supported by a table that also has a hole it.) Also...

0, 1, 2, 9, 44, 265 ... Assume that the sequence has no "randomly" assigned values. That is, that (perhaps apart from the first) all the elements can be deduced from the index integer (n=1,2,3, etc) and the preceding values of the sequence. I don't claim there is a unique solution or...

I'm sure most of us have, at one time or another, thought of silly greetings to leave on our answering machine. I have recently come up with one that I wish to share. I would also like to know if anyone here is the legal expertise to tell me whether or not I can legally enforce the following...
